Underground comprehensive pipe gallery pouring formwork system

Abstract

The invention discloses an underground comprehensive pipe gallery pouring formwork system. The underground comprehensive pipe gallery pouring formwork system comprises a bin inner formwork and a bin outer formwork which are used for pipe gallery concrete pouring lining; the bin outer formwork is hoisted and moved through a crane and is matched with the bin inner formwork after being fixed to achieve concrete pouring; and the bin inner formwork comprises at least two sets of formwork combinations, and the two sets of formwork combinations can be loaded and moved through a trolley to penetrate through each other to achieve alternate and continuous concrete pouring and equal-strength construction. According to the system, a variable formwork combination structure is adopted, the formwork combinations are carried and moved through the trolley, pouring and demolding are supported, the formwork combinations penetrate through the formwork combinations to be poured after demolding is achieved through a folding or telescopic structure, and alternate and continuous concrete pouring lining construction is achieved. By means of the system, the concrete lining quality can be improved, and the size, precision, appearance and quality of a concrete pouring body are higher; meanwhile, the problems that the labor intensity of workers is large, the labor cost is high, and mechanical equipment such as a large-tonnage crane needs to be arranged at any time are solved; and the overall construction efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of construction machinery design, in particular to the design technology of building construction formwork systems, in particular to a formwork system for pouring underground comprehensive pipe galleries. Background technique [0002] The urban underground comprehensive pipe gallery is an urban underground infrastructure, which plays an irreplaceable and important role in the basic functions of the city. Build a tunnel space underground in the city, integrate various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., and set up special inspection ports, hoisting ports and monitoring systems, and implement unified planning, unified design, and unified Construction and management are the important infrastructure and "lifeline" to ensure the operation of the city. [0003] The concrete lining construction of the pipe gallery, because of its square flat roof struc...

AI Technical Summary

Problems solved by technology

Wooden formwork / simple steel formwork+scaffold support lining method, the main problem is poor accuracy and quality of concrete lining, high labor intensity, high labor cost, low efficiency, and large-tonnage cranes are required on site at any time

[0005] The lining scheme of two lining trolleys is adopted, the lining period is long, the construction efficiency is low, and the equipment investment cost is high, which cannot meet the needs
