The prefabricated assembly type inspection well is good in integrity and few in-site concrete operation, but the conventional assembly type inspection well is generally formed by assembling a bottom plate, an upper well chamber, a lower well chamber, a contraction opening, a shaft, a well cover and the like, except the well cover, the rest parts of the assembly type inspection well are installed by adopting mechanical hoisting, and certain difficulty is brought to later-stage maintenance. The modular inspection well adopts masonry construction, the process is convenient and flexible, the modular inspection well has the advantages of good pressure bearing, shearing resistance, low manufacturing cost and corrosion resistance of a concrete structure, but the modules need to be cut on site at the pipeline joint of a well chamber, and the overall masonry speed is reduced.
In recent years, with the rapid increase of traffic flow, the settlement phenomenon of the inspection well of the urban road is very common, so that the flatness of the road surface is reduced, and the driving comfort and the safety are influenced. Compared with the traditional brick inspection well, the reinforced concrete inspection well has great promotion in the aspect of settlement resistance, but along with the increase of the service life of the inspection well, the settlement and the subsequent maintenance problems are inevitable. At present, for the pavement damage caused by the settlement of the inspection well, a mode of adjusting a well ring is generally adopted, namely the well ring is firstly removed when the settlement occurs, fast hardening mortar and concrete are used for bedding and leveling, and then the well ring is installed again. The method needs concrete wet operation and maintenance, and brings certain influence on timely recovery of road traffic.
The publication number CN2546500Y is named as prefabricated concrete inspection well, the well chamber and the shaft are assembled by prefabricated reinforced concrete adjusting splicing blocks, the vertical direction between the adjusting splicing blocks is a tongue-and-groove joint, and the adjusting splicing blocks are sealed by polyurethane, rubber rings or cement mortar. Compared with a brick inspection well, the structure has the advantages of high construction speed, high quality and high compressive strength, is favorable for solving the problems of road well ring collapse and the like, and is produced industrially at present. However, each assembly block must be matched with hoisting equipment for construction, and the construction efficiency is influenced to a certain extent.
The publication number CN108331026A is named as a prefabricated reinforced concrete inspection well and a construction method thereof, and a well chamber and a shaft of the prefabricated reinforced concrete inspection well are connected by adopting prefabricated plate-shaped components through corner posts with grooves and tongues, so that rapid assembly can be realized. But each prefabricated plate block of the structure has a great self weight and is matched with hoisting equipment during assembly. In addition, after all prefabricated components of well room and pit shaft are assembled in place, still need make the structure become whole through tightening up the turn buckle, in case the inside disease that appears of structure, overhaul and change are more difficult.
