Fabricated precast concrete pipe gallery for urban underground freight and manufacturing method of fabricated precast concrete pipe gallery

Abstract

The invention discloses a fabricated precast concrete pipe gallery for urban underground freight and a manufacturing method of the fabricated precast concrete pipe gallery. The fabricated precast concrete freight pipe gallery integrating a gallery body, a bearing platform and sleepers is designed, the appearance is round and tubular, a bottom bearing platform foundation table top is convenient to produce and construct, a prestressed centrifugal process is adopted for production, manufacturing is simple, concrete is compact, the anti-seepage performance is good, concrete rabbets are designed at the joints, sealing rubber strips surround the rabbets, and the joints have good sealing performance. Transportation and hoisting are convenient, industrialized production is achieved, the concrete strength is high, the quality is controllable, and the comprehensive cost is low. A steel reinforcement cage is cured through hot water or steam, a full-automatic seam welder is adopted, industrialized production is achieved, the controllability of the production process is high, the quality is stable, the field operation area is small, few industrial waste is generated, flexible bell and spigot sealing is adopted, the anti-leakage effect is good, the connecting performance is good, the shock resistance is high, and the waterproof performance is good.

Description

technical field [0001] The invention relates to the technical field of road transportation, in particular to an assembled prefabricated concrete pipe gallery for urban underground freight and a manufacturing method thereof. Background technique [0002] At present, the number of cars in various cities is getting higher and higher, urban traffic jams are becoming more and more serious, and air emission indicators are becoming more and more stringent. Daily necessities, daily necessities, agricultural products, etc. are transported from outside the city and dispersed to major cities. Shopping malls, supermarkets, farmers' markets, and industrial and mining enterprises are basically transported by trucks. The daily domestic garbage in the city is also continuously transported out of the city by sanitation vehicles to centralized treatment points, and the return journey of sanitation vehicles is empty, which increases the energy consumption of sanitation vehicles, causes carbon ...

AI Technical Summary

Problems solved by technology

The daily domestic garbage in the city is also continuously transported out of the city by sanitation vehicles to centralized treatment points, and the return journey of sanitation vehicles is empty, which increases the energy consumption of sanitation vehicles, causes carbon emissions, and exacerbates air pollution

[0003] Urban underground freight can solve the problem of traffic congestion very well, but in the existing technology, the transportation and hoisting of the pipe gallery are very difficult, and the on-site operation area is large and there is a lot of industrial waste, which is not conducive to environmental protection
