Abstract

The invention relates to the technical field of road inspection well construction, in particular to a road inspection well and a manufacturing process and a construction method thereof. The concrete is prepared from the following raw materials: Portland cement, medium sand, super absorbent resin, pebbles, a fiber mixture, fly ash, an expanding agent, a polycarboxylate superplasticizer, gravel-typegranules, montmorillonite powder, attapulgite, a retarder, an early strength agent and water. The fiber mixture is used as a raw material for preparing the road inspection well, wherein the fiber mixture is formed by mixing polypropylene fibers and steel fibers according to a certain proportion, as a result, the polypropylene fibers and the steel fibers are matched with each other to effectivelyreduce the volume shrinkage phenomenon of the road inspection well in the early stage, and the anti-cracking performance of the road inspection well is improved; and moreover, proper vibration compaction treatment is carried out on the concrete during pouring, so that the compactness and the uniformity of the concrete are improved and guaranteed, the crack resistance and the bearing capacity of the road inspection well are remarkably improved, and the service life of the road inspection well is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of road inspection well construction, and more specifically relates to a road inspection well and its manufacturing process and construction method. Background technique [0002] The road inspection well is set up for the maintenance and installation of urban underground infrastructure such as power supply, water supply, drainage, sewage discharge, communication, cable TV, gas pipes, and street lamp lines. It is generally installed at the intersection of pipelines, turning places, pipe diameter or slope changes, and at certain distances on straight pipe sections, which is convenient for regular inspection of ancillary structures. Although the road inspection well prepared by the existing technology can facilitate regular price difference ancillary structures, its own crack resistance is poor, and its service life is relatively short. Contents of the invention [0003] The first object of the present inven...
