Abstract

This application relates to a lifting construction structure for inspection wells, which includes a subgrade surface that is flush with the upper end surface of the old inspection well and located around the old inspection well. The upper end surface of the old inspection well is fixedly connected with a new inspection well. The sinking plate, the surface of the anti-settling plate is fixedly laid with a first cement stabilized macadam base, the upper surface of the first cement stabilized macadam base is fixed with a reinforcing plate, and a number of anti-settling columns are inserted between the reinforcing plate and the anti-settling plate, The bottom end of the anti-settling column extends into the soil below the subgrade surface, and there is a fixing piece between the anti-settling column and the reinforcing plate for fixing the anti-settling column and the reinforcing plate, and there is a fixing piece between the anti-settling column and the anti-settling plate. For the anti-settling components of the anti-settling columns and anti-settling plates, the second cement-stabilized gravel base is fixedly laid on the surface of the reinforcement plate, the upper surface of the second cement-stabilized gravel base is fixedly laid with an asphalt layer, and the upper end of the new inspection well is fixed with The closed manhole cover of the present application has the effect of improving the stability of the surrounding structure of the inspection well.

Description

technical field [0001] The present application relates to the technical field of inspection wells, in particular to an inspection well lifting construction structure. 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. Generally, it is installed at the intersection of pipelines, turning places, places where pipe diameter or slope changes, and at certain distances on straight pipe sections, which is convenient for regular inspection of auxiliary structures. Inspection well heightened. [0003] Existing inspection wells are raised by bricks, and the periphery of the inspection well is wrapped with low-grade concrete, and compacted by light machinery. [0004] With regard to the related technologies mentioned above, the inventor believes that there is a def...
