The application relates to an inspection well anti-subsidence structure and its construction method. It is applied in the field of inspection wells. It includes a well body buried in the well pit and a well cover arranged on the upper end of the well body. The outer wall of the well body is provided with a The base ring, the top seat ring is sleeved on the outer wall of the well body above the base ring, and several inner seat rings are sleeved between the top seat ring and the base ring on the outer wall of the well body. The inner side wall of the seat ring matches the outer side wall of the well body, and the space between the base ring and the adjacent inner seat ring, between two adjacent inner seat rings, and between the top seat ring and the adjacent inner seat ring is uniform. The first elastic part is provided, and the upper end of the well body is provided with a retaining ring along the peripheral side, and the top seat ring is provided with a ring groove matching the retaining ring along the peripheral edge, and the top surface of the top seat ring is flush with the upper end of the well body . The application has the effect of making the inspection well difficult to settle and protecting surrounding roads.
Description
technical field [0001] The present application relates to the field of inspection wells, in particular to an anti-subsidence structure for inspection wells and a construction method thereof. Background technique [0002] The inspection well is set up for the maintenance of urban underground infrastructure such as power supply, water supply, drainage, sewage discharge, communication, cable TV, gas pipes, and street lamp lines, and is convenient for installation. It is generally located at the intersection of pipelines, turning places, pipe diameter or slope changes, and at certain distances on straight pipe sections. It is an auxiliary structure that is convenient for regular inspection. [0003] Due to the particularity of the installation location, the inspection well is often trampled by people or rolled by vehicles. Under the action of long-term dynamic load, and its supporting structure is relatively simple, and it is always in a humid and dark environment, the bearing c...
