Description

Technical Field

[0001] The invention relates to the technical field of inspection wells, in particular to a prefabricated assembled inspection well with a bracket structure. Background Art

[0002] Inspection wells are set up to facilitate the maintenance and installation of urban underground infrastructure such as power supply, water supply, drainage, sewage, communications, cable TV, gas pipes and street light lines. They are generally located at pipeline intersections, bends, changes in pipe diameter, changes in slope, and at certain intervals on straight pipe sections to facilitate regular inspection of ancillary structures. In order to improve construction efficiency, existing inspection wells generally use prefabricated parts for on-site assembly. For example, the patent with announcement number CN219952037U discloses a prefabricated assembled inspection well with a corbel structure, including a bottom plate, a lower well chamber without an upper cover and a lower bottom, and an upper well chamber without a lower bottom. The four side walls of the lower well chamber are integrally formed, and the four side walls and the top of the upper well chamber are integrally formed. A step groove is provided around the outer edge of the bottom plate, and the outer edge is lower than the inner part. The bottom of the lower well chamber is seated on the step groove of the bottom plate, and a corbel structure is provided on the inner side of the upper edge of the lower well chamber, and the wall thickness width at the connection of the upper edge of the lower well chamber is greater than the bottom wall thickness of the upper well chamber; high-strength concrete is poured in the gap at the joint of the lower well chamber and the bottom plate and in the gap between the corbel structures of the upper well chamber and the lower well chamber, so as to reduce the number of components and the amount of cast-in-place of the inspection well, thereby reducing the construction difficulty and speeding up the construction speed.

[0003] The existing technology still has the following problems:

[0004] (1) As prefabricated parts are generally heavy, they are usually placed by hoisting. However, during the placement process, the hoisting rope may shake, resulting in an inappropriate placement position, which requires repeated adjustments and reduces construction efficiency.

[0005] (2) A corbel structure is provided on the inner side of the upper edge of the lower well chamber, which only improves the supporting strength of the upper and lower chambers. However, when the pipes are actually connected, the pipes are subjected to greater force on the inside of the lower well chamber due to the force on the pipes, which affects the life of the inspection well.
