Movable subway station side wall supporting steel formwork supporting device and supporting method

Abstract

The invention provides a movable subway station side wall supporting steel formwork supporting device, and belongs to the field of geotechnical engineering. The movable subway station side wall supporting steel formwork supporting device comprises a formwork supporting assembly, a walking assembly, a steel formwork assembly and a ground anchor assembly, wherein the walking assembly is connected with the formwork supporting assembly; the formwork supporting assembly is detachably connected with the formwork supporting assembly; and the formwork supporting assembly is connected with the ground anchor assembly so as to be kept fixed. The invention further provides a supporting method. The supporting method comprises the following steps that S1, the ground anchor assembly is pre-buried; S2, the steel formwork assembly is installed; S3, two supporting frames are connected with connecting cross beam together; S4, each supporting screw rod is adjusted; and S5, the multiple steel formwork assemblies are assembled. The movable subway station side wall supporting steel formwork supporting device and the supporting method have the beneficial effects that the steel formwork supporting device can integrally move, the side wall construction efficiency is improved, and the standardized construction level is improved; and the supporting method is convenient to construct and operate, high in efficiency, high in turnover speed, capable of saving cost, high in safety and reliability and capable of guaranteeing the construction quality of the side wall.

Description

[0002] With the rapid construction of rail transit projects in major cities, in the field of geotechnical engineering, during the construction process of the main structure side wall of underground engineering, the requirements for construction quality and progress are getting higher and higher, and there are many cross operations in subway deep foundation pit engineering. The construction period is tight. According to the construction experience of subway stations, the side walls of the main station were initially constructed with wooden formwork, bamboo plywood combined with a scaffolding support system. There were problems such as large input materials, long construction period, uneven structural appearance quality, and serious water leakage. The problem, after improvement, the fixed assembled steel formwork was used for construction, the work efficiency has been improved to a certain extent, and the structural construction quality is better, but the steel formwork is limited by the steel support space of the foundation pit when it is recycled, so it needs to be disassembled and hoisted by a crane It is transferred to the next construction unit on the ground, reassembled and reinforced, the process is relatively cumbersome, and the workload of personnel and equipment is relatively large, so there is a certain room for improvement
