The method has the advantages of high operation efficiency, high progress, high quality, high safety, easy guarantee and the like.
The technical scheme adopted by the utility model is as follows: adopt a simple and easy prefabricated inspection shaft, its characterized in that: the prefabricated well chamber, the prefabricated cover plate and the prefabricated shaft are provided. The prefabricated well chamber top fixed mounting has prefabricated apron, there is the pit shaft bead in prefabricated pit shaft bottom, be equipped with on the prefabricated apron with pit shaft bead complex reserve concave pit shaft hole, prefabricated pit shaft lower extreme and prefabricated apron realize the socket joint through the cooperation of pit shaft bead and reservation concave pit shaft hole and are connected.
Preferably, waterproof materials are arranged at the joints of the prefabricated well chamber, the prefabricated cover plate and the prefabricated shaft for sealing.
Preferably, the bottom of the prefabricated well chamber is provided with a bottom foundation, the bottom foundation is provided with a flow groove, and the prefabricated well chamber, the bottom foundation and the flow groove are of an integrated structure.
Preferably, pipeline mounting holes for mounting pipelines are formed in two sides of the prefabricated well chamber, and the size of each pipeline mounting hole is larger than the outer diameter of each reserved pipeline.
Preferably, a well cover is arranged on the top of the prefabricated shaft.
Preferably, the prefabricated well chamber, the prefabricated shaft, the prefabricated cover plate and the bottom base material are all made of reinforced concrete.
Preferably, the prefabricated well chamber is a square prefabricated well chamber, and the prefabricated well shaft is a round prefabricated well shaft.
The utility model has the beneficial effects that: when the construction conditions are complex and the difficulty is high, the prefabricated inspection well can be installed in the foundation pit when the soil reaches certain strength. The prefabricated pit shaft, the prefabricated cover plate and the prefabricated well chamber which are connected in a socket joint mode greatly reduce the prefabrication difficulty of the inspection well.
