Generally speaking, enterprises have higher requirements for civil engineers. In addition to supervising and coordinating construction site problems, they should also have high professional quality, be able to supplement and improve construction design and be fully responsible for technology. Therefore, there are often a lot of professional problems to be considered in the interview of civil engineers. The following is a summary of some common questions in the interview of civil engineers:
1. What do you think are the responsibilities of civil engineers?
Answer: The interviewer needs to answer this question from the following aspects. 1, contract; 2. Engineering materials; 3. Project quality, schedule, safety and cost; 4. Engineering data; 5. On-site acceptance. The answer to this question should be because the answer is relatively fixed and there is not much room for free play, so the interviewer should try to prepare the answer to this question before the interview.
2. If you are given a batch of steel bars, how do you accept them?
Answer: 1, know the product certificate, ex-factory inspection report, labels, etc. Steel bar; 2, steel varieties, models, specifications, quantity, location, etc. ; 3, steel bar connection mode, joint position, joint number, lap length, joint area percentage; 4. Varieties, specifications, quantity and spacing of stirrups and transverse reinforcement; 5. Specification, quantity and location of embedded parts.
3, mass concrete construction method? What are the main measures to prevent cracks in concrete due to temperature difference?
Answer: 1, slag cement with low calorific value and long initial setting time should be selected in construction; 2, according to the specific situation of the construction, try to choose 5-40mm stones, increase the orthopedic particle size, can reduce the dosage of cement, reduce the hydration heat; 3. Choose suitable retarder (such as necessary calcium sulfonate) and admixture (fly ash) to reduce the cement consumption and hydration heat; 4. When pouring concrete, the working face should be enlarged as much as possible to slow down the pouring speed and thickness. After concrete pouring, it should be vibrated for the second time before initial setting to prevent cracks from appearing when concrete sinks. 5, mass concrete pouring mass concrete in summer, can use water conservation method, pouring mass concrete in winter, in order to prevent the surface temperature heat dissipation too fast, covering heat preservation materials or short-term heating method should be adopted. (PS: This question is highly professional, and the examinee examines the interviewer's technical problems in construction. If you can't understand it well, I suggest you memorize this question before the interview. )
4. What are the protection works for civilized construction on site? Simply put.
A: There are six civilized construction guarantee projects. 1. Fences shall be set around the construction site, requiring 2.5m in the urban area and1.8m in other areas; 2, with the gate and the guard closed management, has nothing to do with the construction personnel are not allowed to enter; 3, hardening treatment on the construction site; 4. List each other's materials according to the general plan; 6, homework and living quarters should be separated; 7, the scene set fire control measures.
Please describe the principle and preventive measures of floor "three cracks"?
Answer: The reasons for "sanding, peeling and shelling" are: insufficient cement grade or use of expired cement, too thin mortar, insufficient plastering times, poor maintenance and so on. The causes of cracking are: the sand is too fine, the floor base is not cleaned cleanly, the plain cement surface is uneven, the plastering is not dense, the frame joints are not well done, the mortar layer is too thick or the base is not wet enough. Preventive measures: strictly control the cement grade, use coarse sand, with the silt content not more than 5%, clean the base course and cut the hair, sprinkle water one day in advance for wetting, brush a 1: 0.40-0.45 plain cement slurry before pouring, set grid bars at the door and perforated plate, plaster the surface in three times, strictly control the plastering time, and maintain it in time after 24 hours.
6. Why do you want to check the groove after the foundation groove is excavated in place? What are the key points of slot position inspection?
Answer: After the foundation trench is excavated in place, the purpose of trench inspection is to check whether the basement bearing layer meets the design requirements and is consistent with the engineering geological survey report. Key points of slot inspection: 1. Check the axis position, plane size and elevation of the trench bottom; 2. Check the soil quality and groundwater of the base tank; 3. Whether there are underground buried objects such as potholes, ancient tombs, ancient wells and air-raid shelters.
7, please describe the unit engineering quality acceptance conditions?
Answer: 1, the quality of sub-projects included in the unit project should be qualified; 2, quality control data should be complete; 3, the unit project included in the division of the project related to safety and functional inspection information should be complete; 4, the main function of the project inspection results should comply with the relevant professional quality acceptance specifications; 5, visual quality acceptance should meet the requirements.
8. What are the treatment methods for honeycomb and holes in concrete?
Answer: 1, for a few small honeycomb and exposed concrete surfaces, 1: 2 cement mortar plastering can be used to correct them; 2. When the area and depth of honeycomb and holes are large, the method of injecting cement slurry at high pressure can be adopted; 3, honeycomb, hole is bigger and deeper, but not through, can be local chisel in addition to the concrete, funnel template, with a higher level of concrete or UEA micro expansive agent is poured and compacted, chisel in addition to the excess when reaching strength; 4, honeycomb, serious holes, should chisel in addition to the whole component, shuttering is poured concrete and then clean up, and handle the adjacent surface.
