Rapid continuous construction method of single-compartment large-section cast-in-place frame-structure pipe gallery

Abstract

The invention discloses a rapid continuous construction method of a single-compartment large-section cast-in-place frame-structure pipe gallery. The rapid continuous construction method comprises thefollowing steps: inner die plates on inner die trolleys and outer die plates on outer die trolleys are slightly adjusted through corresponding hydraulic rods, the die assembly and the adjustment are performed, the structural size and line style are determined, and then top plate reinforcing steel bars are bound; the pouring of concrete is performed, the inner die plates on the inner die trolleys are lowered and retracted through the corresponding hydraulic rods, the outer die trolleys are expanded and raised, and the corresponding die plates are dismounted; the outer die trolleys and a curingshed are moved forward, the outer die trolleys are moved to another inner mold trolley, the jumping-type construction is performed, and the above concrete section for pipe gallery forming is subjectedto spray curing; and after the concrete strength requirement is met, the inner die trolleys are moved forward. The rapid continuous construction method has the beneficial effects that the concrete staggering phenomenon caused by the splicing of small die plates can be avoided; pull ribs and holes generated due to the conventional die plate reinforcing process can be eliminated; the construction repair cost can be effectively reduced; and through the automatic retraction, rise and fall of the hydraulic rods, the automatic mounting and dismounting operation can be performed, and the conventional construction labor and construction time can be reduced.

Description

technical field [0001] The invention relates to the field of pipe gallery construction, in particular to a rapid and continuous construction method for a single-cabin large-section cast-in-place frame pipe gallery. Background technique [0002] With the rapid development of society and the increasing use of underground space, there are more and more constructions of underground structures such as subways and frame bridges. In the construction of underground pipe corridors, the structural construction mostly uses square wood, formwork and steel pipe support system for construction, while ordinary formwork support has many construction procedures, long installation and dismantling time, high rental cost of support, and the construction quality of wooden formwork after many turnovers. It is difficult to guarantee, and the construction period is long, which greatly restricts the rapid construction of urban pipe corridors. Ordinary formwork support has many construction procedur...

In the construction of underground pipe corridors, the structural construction mostly uses square wood, formwork and steel pipe support system for construction, while ordinary formwork supports have many construction procedures, long installation and dismantling time, high rental costs of supports, and the construction quality of wooden formwork after many turnovers. It is difficult to guarantee, and the construction period is long, which greatly restricts the rapid construction of urban pipe corridors

There are many construction procedures for ordinary formwork supports, long installation and dismantling time, large labor demand, and concrete misalignment caused by loose splicing of small formwork; the cost of support rental is high, and the steel pipe reinforcement method has great safety hazards; the wooden formwork will be constructed after many turnovers The quality is difficult to guarantee, and the construction period is long, which greatly restricts the rapid construction of urban pipe corridors; the traditional formwork reinforcement uses water-stop tie rods to cause holes in the concrete; the quality of concrete maintenance in traditional construction is difficult to control, and the strength of concrete rises slowly. With the use of tie bars, it is difficult to guarantee the waterproof quality of the gallery, and it is a waste of manpower and material resources to repair the tie holes
