Third, the internship content
Due to the limited internship time, I only participated in some project budgets and several small project budgets. Now make a brief summary as follows:
1. Collect and master all kinds of engineering-related information (such as a complete set of construction design drawings and related standard drawings, budget quota of construction projects or valuation table of regional units, current budget price of materials, various charging standard documents, etc.). ).}
2, familiar with the audit of construction drawings {construction drawings and related standard atlas from coarse to fine, from the whole to the details of the audit, on the one hand, make the whole picture of the project rooted in the brain; On the other hand, mistakes can be made to the relevant units, which is convenient for revision or supplement and is conducive to the smooth progress of the budget. }
3, in-depth field and relevant departments to understand the situation (such as field soil weight category, earth moving distance, construction method, semi-finished components processing position, etc.). Everyone should know clearly in order to use the quota. }
4. Calculation of quantities {After the above preparatory work is completed, the quantities of various subdivisional works can be calculated according to the description and calculation rules of budget quota.
5. Apply the budget unit price to calculate the direct cost {the budget unit price is not only the budget quota but also the base price or unit price in the unit valuation table. After the engineering quantity is calculated, the following formula is used: direct cost of each subproject = engineering quantity of subprojects ╳ * budget unit price.
Among them, subdivisional work refers to projects divided by different specifications, different materials and different construction methods. For example, foundation engineering is divided into sub-projects such as foundation pit excavation, lime-soil cushion and foundation bricklaying, and wall engineering is divided into sub-projects such as external wall, internal wall and clay solid brick wall.
The direct cost of each division = the sum of the direct costs of each subdivisional work.
Among them, the division project refers to the project divided by building parts. Budget quota is divided into earthwork, pile foundation and foundation pit supporting engineering, masonry engineering and scaffolding engineering.
Direct cost of unit project = sum of direct cost of each division project}

Understanding the internship process has broadened my horizons, and at the same time I have mastered some basic professional knowledge.
After a year's internship, I learned a lot of professional-related knowledge, and also learned a lot of basic architectural knowledge during my internship. Knowing this knowledge will be of great help to our future professional study.
Summary of civil engineering practice II 2000 words
I learned a lot from this internship in Shenyang. This internship has taught me something that is not in the textbook. The concrete examples are quite different from those in the book. In this internship, we visited Phoenix, Olympic Sports Center, Shenyang University, expressway and Hunhe Bridge.
We went to Shenyang Olympic Sports Center by bus. When we went, the site was in full swing. We saw workers wearing hats of different colors at the construction site, which made us curious. Why are they wearing hats of different colors? Later, after the introduction of the staff, I learned that the yellow is the construction personnel, the white is the management safety, the blue is the supervision, and the red is Party A. The whole Shenyang Olympic Sports Center project is a three-hall layout. A game? For the main stadium; ? Three pavilions? It is a comprehensive gymnasium, swimming pool and tennis court. The main stadium is the most important thing in the construction of the Olympic Sports Center. The main stadium of the Olympic Sports Center has a construction area of 6.5438+0.4 million square meters, accounting for more than half of the total area of the Olympic Sports Center. Upon completion, 60,000 spectators can watch the game in the stadium at the same time.
We found it online before we came back. What's the appearance? Crystal crown? +? Wings? From the appearance, the main stadium looks like a crystal crown in the hands of the goddess of victory (see the eye picture in a newspaper), while the east and west indoor venues look like a pair of wings of the goddess of victory. ? The relevant person in charge of Shenyang Planning Bureau explained the design concept of the Olympic Sports Center.
It consists of two structures, the grandstand is reinforced concrete structure, the roof is arched steel structure, and the arched roof consists of six steel structures, three in the east and three in the west. This structural layout not only reduces the construction difficulty, but also streamlines the appearance of the venue.
There are two internal supports+100 box. In the design of the main stadium, many internationally popular concepts have been applied in the main stadium of the Olympic Sports Center.
There is a gap between every two of the six arched membranes, which not only ensures the air circulation in the venue, but also effectively avoids the problem that other large venues produce echoes and the audience can't hear the broadcast clearly.
It is worth noting that the roof of the main stadium adopts transparent materials such as solar panels and glass, which makes the lawn in the stadium fully enjoy the sunshine and improves the maintenance cycle of the lawn.
In addition, the main stadium of the Olympic Sports Center will break the three-story stand mode of most venues and adopt a two-story stand structure.
The view of the stands on the third floor is very steep, so it is inhuman for the audience sitting on the third floor to watch the game. In contrast, the two-story stands are much more comfortable. In addition, a 100 VIP box was specially set up between the first and second floors to welcome domestic and foreign VIPs. Construction of Shenyang Olympic Sports Center started, and the football match of the 20xx Olympic Games started here. Two years later, when you stroll along Hunnan Avenue in the evening, you will find a crystal crown building in front of you, with warm shouts from time to time? This one? Crystal crown? It is the long-awaited Shenyang Olympic Sports Center for 7.2 million people in Shencheng, and also the football field for the 2008 Olympic Games. When we came out of the Olympic Sports Center, the staff introduced us that the Olympic Sports Center not only had a beautiful appearance, but also its most special security system. The room between the first floor and the second floor is equipped with a power room. If there is an accident, you can supplement the power room without the audience feeling it at all, so as to avoid the confusion of the venue after the stop. The truth is amazing. After watching the Olympic Sports Center, I feel it must be a pleasure to watch the ball game here.
The Phoenix Wing of Shenyang World Expo Park is located in the Expo Park in Shenhe District, Shenyang. It is also one of the four landmark buildings in the Expo site, and it is a cable-stayed bridge. Phoenix Wing is located in the main entrance square of the Expo Park, which is the gate of the park, with a building area of 4 168 square meters and a main tower height of 72 meters. Wings of Phoenix? The total length is 2 10 meter, and 10 stay cables run through it. The overall shape of the building is like a phoenix spreading its wings, symbolizing revitalization and take-off. This building was originally named? Wings of prosperity? Officially named after the suggestion of experts? Wings of Phoenix? , symbolizing that Shenyang is like a phoenix nirvana? Reborn from the fire? After taking off.
Next, we visited the Hunhe River and its beaches on both sides, which is an urban ecological belt integrating ecological greening, sports and leisure, tourism, flood control and drainage. The downtown area connects the eastern tourist attractions and runs through the west. Western industrial corridor? . Construction of beach sports area. Combined with the main entrance and exit of the beach, public service facilities such as catering, retail, toilets, docks, tourist stations and bicycle rental points will be set up around the parking lot.
In the future, the transportation modes of Hunhe Beach will include: cars, battery cars, bicycles, walking and boats. Sightseeing roads are divided into three levels: motor vehicle lanes, bicycle lanes and tourist walkways. North beach plans expressway, with a width of 7 to 9 meters; Waterfront bicycle lanes are set up on the north and south beaches, with a width of 6 meters; The planned width of the pedestrian walkway for tourists is 2 to 3 meters.
Hunhe Bridge was completed and opened to traffic on June 165438+ 10/4, 2003. The total cost of the bridge is more than 40 million yuan, the bridge is 49 and 5 meters wide, with two-way 10 lanes, in which the motor vehicle lanes are 36 and 5 meters wide, and the non-motor vehicle lanes on both sides are 6 and 5 meters respectively, which greatly improves the traffic and bearing capacity of the Hunhe Bridge. Each group of 6-8 drainage holes with a diameter of 10 cm are arranged at the edge of the roadway. He Qiao, located at the south gate of Shenyang, is the traffic artery connecting Shenyang urban area and Hunnan New District. It can prevent floods once in 300 years.
Because Hunhe River is the main river in Shenyang, it is specially designed for flood control. (www.7lizhi.com) The height of the whole bridge is about 1 m higher than that of the once-in-300-year flood. Two 22-meter-wide and 5-meter-wide bridge arches are set on both sides of the bridge body, and 14 33-meter-wide bridge arches are set in the middle, which can reduce the scouring of the bridge body by floods and strengthen the stability of the bridge body.
Old Hunhe Bridge was built in 1942? Fake Manchu? During the period, the total length is 664 meters and the width is 9 meters. The overall structure of the bridge is double cantilever type, and the pier is a three-column structure (the pier is supported by three columns side by side). There are 30 holes in the bridge, of which 28 holes in the middle span 22 meters and 65,438+05 meters on both sides. The bridge foundation is 9 meters deep and the bearing capacity is 10 ton. This bridge is the earliest bridge on Hunhe River in Shenyang. At the beginning of its construction, it played an important role in the traffic on both sides of the Hunhe River. In 2003, 1 year-old' Old Hunhe Bridge' was demolished by blasting at about 4 am on February 19, leaving only the pier between 17 and 18 as a memorial! !
We saw many bridges, and then we came to China, expressway, Shenyang and expressway, Dalian. It passes through Liaoyang, Anshan and Yingkou, with a total length of 375 kilometers. The longest expressway in China (as of May 1993, 1). Construction started in June, 1984, and the construction was promoted from the north and south ends to the middle. It was completed and opened to traffic on August 20th. 1990. All the projects were designed and built by China. The roadbed is 26 meters wide, divided into four lanes, 3 meters wide in the middle, and emergency parking areas are set on both sides. It's all asphalt concrete pavement.
All entrances and exits are controlled and interchanges are used. The design speed in mountainous area is 100 km/h, and that in other areas is120 km/h. The Pulandian Bay Bridge, with a length of1.206m, will be built along the line. Bridge 15, length 100 m; There are 384 small and medium-sized bridges and 26 interchanges. There are 13 microwave communication stations, 6 service areas, 6 parking lots and 7 management offices along the line. On Shenyang-Dalian expressway, a military airstrip with a length of 2800 meters and a width of 50 meters was built by widening the earth shoulders on both sides. Shenyang-Dalian expressway runs through Liaodong Peninsula, making this industrial corridor a whole, connecting Dalian Port, Yingkou Port and Bayuquan Port with the three northeastern provinces and the vast hinterland of eastern Inner Mongolia. Expressway and Shenyang-Dalian are important traffic arteries in Northeast China, and they are also the major channels to safeguard national defense. After 18 months of intense construction, three Fumin bridges, the first in the world, were officially completed and opened to traffic, and the construction of Fumin Street, the extension road of Fumin Bridge North Approach Bridge, was also completed. Secretary of the Municipal Party Committee, Mayor Chen, Director of the Standing Committee of the Municipal People's Congress Cui Wenxin and Chairman attended the opening ceremony. What's the name of Fumin Bridge? Prestressed concrete cable-stayed bridge with twin towers and three spans, single cable plane, broken line and inclined tower? , located in cheung tsing bridge, about two kilometers downstream of Hunhe River; The southern end is connected with the newly-built east-west Hunnan Avenue, and the northern end is connected with Cui Wen Road, with a total length of 932 meters, a main bridge of 420 meters, a south approach bridge of 242 meters and a north approach bridge of 270 meters, with a width of 32 and 5 meters and six lanes in both directions. The two leaning towers are 67 meters high, 5 meters high, and the dip angle of the lower section of 3 1 meter is 7 degrees; Each leaning tower is correspondingly arranged with 15 pairs and * * 120 stay cables, with a diameter of 15cm, which is fan-shaped and very beautiful. Fumin Bridge is novel in design, unique in structure and profound in meaning? The Twin Towers, like a pair of powerful giant hands, hold up a bright tomorrow in Shenyang.
Fumin Bridge consists of main bridge, approach bridge, approach roads on both sides and ancillary works. The whole project has created three firsts in the world: first, the main bridge adopts the inclined tower of broken-line prestressed concrete, which is the first at home and abroad; Second, the two main towers adopt different structural support systems, that is, the south tower pier adopts tower-beam-pier consolidation system, and the north tower pier adopts tower-beam binding and beam-pier separation system. This is the first time in the world that two different support systems have been applied to a bridge. 3. The North Tower Pier adopts three super-tonnage basin-type pearl steel bearings, of which one bearing capacity is 1. 3 million tons and the other two bearing capacity is 8,000 tons. First support? .
On behalf of the Municipal Party Committee and the Municipal Government, Vice Mayor Xing Kai congratulated the completion and opening of Fumin Bridge and Fumin Road. He said that the completion of Fumin Bridge and Fumin Street not only further improved the traffic conditions on both sides of Hunnan River, but also brought Hunnan New District closer to the mother city, further optimized the urban development pattern echoing the north and south, and had a positive and far-reaching impact on promoting the development and construction of Hunnan New District.
