Method for integrally and transversely moving high and large formwork through high and large trolley

Abstract

The invention relates to the technical field of tunnel construction, and provides a method for integrally and transversely moving a high and large formwork through a high and large trolley. The method comprises the following steps: the formwork is connected through a partial loading beam and a fixing clamp on the trolley; the formwork is controlled to be upwards or downwards adjusted through a longitudinal adjustment pull rod on the trolley; the distance between the formwork and the wall surface of a wall body is adjusted through a horizontal adjustment rod on the trolley; the trolley is moved through a sliding rail after pouring is completed; the trolley drives the formwork to integrally move to a second section. According to the method, after one pouring operation is completed, all needed is to loosen the formwork and move the trolley to a next pouring section to perform formwork mounting, and the problem that quantity of work is high because the formwork is required to be dismounted and is assembled again in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of tunnel building construction, in particular to a construction method of a tunnel wall, and more particularly to a method for using a tall trolley to move a tall formwork laterally as a whole during the construction of the tunnel wall. Background technique [0002] In the concrete pouring process of the tunnel wall, it is often necessary to use tall formwork. For example, the open section of the west artificial island of the island tunnel project of the Hong Kong-Zhuhai-Macao Bridge has a tunnel wall height of more than 10m and a length of more than 15m. The formwork used is tall formwork, and It has the characteristics of many template units, that is, there are many small templates, and the large template needs to be assembled by small templates. [0003] In the prior art, the general construction method of the tunnel wall formwork is as follows: after the steel bars are bound, the formwork is assembled b...

Problems solved by technology

[0003] In the prior art, the general construction method of the tunnel wall formwork is as follows: after the steel bars are bound, the formwork is assembled by lifting equipment such as a crane. formwork, and then hoist the formwork with a crane to the next section of the work surface that needs to be poured for reassembly and installation. This is more practical for small projects or small components, but it will increase a lot of demolition, formwork removal, and assembly of large components. The workload of the mold not only makes the construction work extremely cumbersome, but also increases the construction time, reduces work efficiency, and consumes too much manpower and material resources.
