Building community (residential area, public **** building area, factory, etc.), urban and rural municipalities, industrial parks, old city renovation, etc. within the scope of buried drainage pipe outer diameter is not greater than 1200mm, buried depth is not greater than 8m plastic drainage check well project design, construction and maintenance. General soil, soft soil soil.

Seasonal permafrost soil and wet loess soil conditions of plastic drainage check well construction; seismic defenses cracking degree of 9 degrees and 9 degrees below the region. The ground load of the general driveway is designed according to the total weight of the car 15t (rear wheel pressure 5t); the ground load of the fire lane is designed according to the total weight of the car 30t (rear wheel pressure 6t). Groundwater level is designed at no higher than 1.0m below the ground.

Inside the buried plastic drainage pipe outside diameter is not greater than 800mm, buried depth is not greater than 6m, generally located in the drainage pipe intersection, turn, pipe diameter or slope change, water fall, etc., in order to facilitate regular inspection, cleaning and unblocking or down the well to operate the inspection of plastic injection molded into a plastic one or brick well-like structures.

Expanded Information:

Plastic one-piece injection molded inspection wells are mainly used in one-time injection molding. Molding, well socket with 360 degrees ring bearing platform, well body and well base bottom with mesh reinforcement, each socket with ring reinforcement design. Depending on the number and angle of the receiver, there are starting wellheads, straight wellheads, 45-degree elbow wellheads, tee wellheads, four-way wellheads and so on.

In order to adapt to a variety of drainage conditions, plastic inspection wells at the same time supporting a reducer joints, confluence joints, wellheads and other matching plastic injection molding accessories. In order to guarantee the smoothness and sealing of the whole drainage system.
