The invention discloses a subway tunnel construction segment supporting device which comprises a storage barrel, a plurality of supporting assemblies are placed in the storage barrel, one side of the storage barrel is rotatably connected with a rotating rod, a threaded groove is formed in the inner wall of the storage barrel, each supporting assembly comprises a circular block, the circular blocks are slidably connected with the rotating rods, and a plurality of arc-shaped mounting grooves are formed in the outer circle of each circular block. Arc-shaped supporting rods are rotationally connected into all the arc-shaped mounting grooves, torsional springs are arranged at the rotating joints of the arc-shaped supporting rods and the circular blocks, placing grooves are formed in the side walls of all the arc-shaped mounting grooves, fixing assemblies are arranged in all the placing grooves, the outer circles of the circular blocks are fixedly connected with sliding blocks, and the sliding blocks are located in the threaded grooves and are in sliding connection with the storage barrel. By detecting water seepage and supporting in time, grouting reinforcement can be conveniently conducted on the water seepage position in the follow-up process.
Description
technical field [0001] The invention belongs to the technical field of segment support, and in particular relates to a segment support device for subway tunnel construction. Background technique [0002] With the development of urban underground engineering construction, especially the rapid development of urban subways in my country, the scale of tunnel engineering construction is getting larger and larger, and the requirements for construction technology level are getting higher and higher. In recent years, shield tunneling method has been widely used in tunnel engineering construction and has achieved considerable development. Shield tunneling method is a fully mechanized construction method in underground excavation construction. This method has the advantages of fast excavation speed, relatively It has the advantages of safety, high degree of mechanization, no blocking of ground traffic, and little impact on climate and environment. The existing supporting structure ca...
