Well bore for fire-fighting detection of water supply and drainage

Abstract

The invention relates to a water supply and drainage fire-fighting inspection pitshaft which belongs to environmental protection equipment and is public road equipment, in particular to a water supply and drainage fire-fighting inspection pitshaft for an urban road, which is manufactured by urban construction waste. The water supply and drainage fire-fighting inspection pitshaft consists of an upper pitshaft (1), a shaft bottom plate (2), a semi-closed preformed opening (3), an upper pitshaft mounting sleeve opening (4), a stubble-type tennon opening (5), an intermediate adjusting sleeve (6) and a lower pitshaft (7). The invention adopts the construction waste to manufacture the water supply and drainage fire-fighting inspection pitshaft, not only reduces waste dumpage but also manufactures the high-strength water supply and drainage fire-fighting inspection pitshaft, attains two objectives by a single move, lightens environmental pollution, and meets the demand of the water supply and drainage fire-fighting inspection pitshaft of an urban construction road.

Description

Technical field: [0001] The utility model relates to a water supply and drainage fire inspection shaft, which is a road public facility, and belongs to environmental protection equipment products, and particularly relates to the manufacture of urban road water supply and drainage fire inspection shafts by using urban construction waste. Background technique: [0002] At present, the city is expanding rapidly, and there is no place for construction waste to be dumped, occupying land and polluting the environment; the finished concrete water supply and drainage fire inspection well is not only made of a large amount of sandstone cement, but also surrounded by blue bricks, which is labor intensive and consumes a lot of building materials. The strength and quality are not satisfactory, which often affects the quality of the project. Invention content: [0003] The purpose of the invention is to use construction waste to manufacture fire-fighting inspection shafts for water sup...
