Construction method of split-through concrete pouring with full-hydraulic self-propelled formwork trolley

Abstract

The invention discloses a split crossing type concrete casting construction method of a full-hydraulic self-walking formwork trolley. According to the inner profile size of a middle plate and a top plate of the section of a required building structure and the distribution of middle columns, a formwork trolley group section of two or more single-body full-hydraulic self-walking formwork trolleys is arranged; according to the segmented form of the length structure of the building structure and the construction cycle time of concrete meeting demolding strength, two or more formwork trolley group sections are arranged, and crossing alternating concrete construction is conducted. The method is used in urban underground metro section and station lining concrete construction, the problem that concrete does not meet the requirement of demolding strength and demolding can not be conducted is solved, construction speed is not influenced, higher smoothness is achieved, the steel-structure formwork trolley meets the requirement of variable section and variable width, construction is more convenient, controllability is higher, and the efficiency of work, material and machine is improved.

Description

technical field [0001] The invention belongs to the technical field of underground engineering construction, and in particular relates to a split-through concrete pouring construction method performed by a fully hydraulic self-propelled formwork trolley. Background technique [0002] At present, in the concrete construction of subway sections and station linings underground in cities, the middle and roof spans are large and variable, there are columns in the middle, and upturned beams are placed on the bottom plate, so the formwork construction requirements are more adaptable. The concrete construction of the middle plate and roof lining usually adopts steel pipe scaffolding or buckle scaffolding as the supporting system, and the formwork is laid. However, it takes a long time to build, the process is cumbersome, there are many operators, and there is a lot of mutual interference, which is labor-intensive and time-consuming. During manual construction, there are many uncont...

Problems solved by technology

However, it takes a long time to build, the process is cumbersome, there are many operators, and there is a lot of mutual interference, which is labor-intensive and time-consuming.

During manual construction, there are many uncontrollable safety factors, high safety risks, and difficult management

The conventional integral hydraulic formwork trolley is used for construction. When walking, the upright column and the lower turning beam cannot be avoided. Moreover, because the concrete thickness of the middle plate and the roof plate is thick, it takes a long time for the concrete to solidify to reach the demoulding strength, and the formwork trolley enters the next step. The cycle takes too long, seriously affecting the construction period
