Construction method for concrete pouring of support-changing type formwork trolley and underground channel

Abstract

The embodiment of the invention discloses a construction method for concrete pouring of a support-changing type formwork trolley and an underground channel. The support-changing type formwork trolley adjusts a top formwork and a side formwork in place through a vertical lifting device and a lateral stretching device respectively, the formwork releasing process and the formwork supporting process are mainly implemented by mechanical equipment such as a hydraulic oil cylinder, the manual work quantity is greatly reduced, the support-changing type formwork trolley can bypass a foundation pit inner supporting system below a structure top plate of the underground channel when moving through a walking support-changing device installed on a supporting base assembly, a structure side wall and the structure top plate are poured at a time under the condition that the supporting system below the structure top plate of the underground channel is not detached, the structure top plate and the structure side wall of the underground channel are integrally formed, the construction technological processes are reduced, the construction period is shortened, the labor cost and the construction cost are saved, and the construction efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of concrete pouring, and in particular to a construction method of a support-changing formwork trolley and an underground passage concrete pouring. Background technique [0002] With the development of economy and the progress of society, large-scale cities are developing rapidly, and the utilization space of surface roads is becoming smaller and smaller. The development of underground passages is one of the effective ways to solve surface traffic congestion. Therefore, more and more underground passages need to be constructed. [0003] The construction process of the underground passage includes the excavation of the foundation pit and the pouring of the concrete structure. When the foundation pit is excavated, the enclosure structure and the internal support system are generally combined to ensure the stability of the foundation pit and prevent accidents such as collapse. After the excavation of the foundation ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a construction method for supporting formwork trolley and underground passage concrete, so as to solve the problem that the existing concrete pouring construction operation uses dense steel pipes to support the formwork, and there is a large occupation of the temporary construction site and safety. High risk, long construction period and high cost
