A device for referencing negative rings of steel structures with super-large cross-section rectangular pipe jacking construction

Abstract

The invention relates to a device for referencing the negative ring of a super-large cross-section rectangular pipe jacking construction steel structure, which effectively solves the problem of the high cost of concrete prefabricated pipe joints used as the negative ring in the process of jacking the pipe jacking machine out of the hole in the prior art and the production cycle. long, difficult post-processing, high risk of hoisting, and low turnover; the technical solution is to include multiple sets of single-ring steel structures that are detachably connected to each other, and each set of single-ring steel structures is slidingly connected Fixedly connected in the two slide rails on the ground, each group of single-ring steel structures includes vertical supports that are slidably connected in the two slide rails, and the lower ends of the two vertical supports can be detachably connected with arc-shaped bottom supports. The supports are connected by connecting beams, and the two vertical supports can be detachably connected with steel supports; the invention has a simple structure, is easy to operate, and can effectively realize the turnover and recycling of the negative ring of pipe jacking, thereby greatly reducing the negative ring. The cost of construction and use is low, the later turnover is easy to lift, and the practicability is strong.

Description

technical field [0001] The invention relates to the technical field of pipe jacking equipment, in particular to a device for referencing the negative ring of a super-large-section rectangular pipe jacking construction steel structure. Background technique [0002] In recent years, with the improvement of the degree of urbanization, the urban population is increasing day by day. In order to alleviate the traffic congestion, many cities need to build elevated roads or tunnels as fast passages. In order to avoid damaging the environment and affecting the current traffic, tunnels planned and designed on urban arterial roads are not suitable for open-cut construction, but can only be constructed by underground excavation. Rectangular pipe-jacking tunnel construction has a high utilization rate of underground space, and can realize shallow-covered soil jacking construction. At present, most of the super-large-section pipe jacking machines are rectangular-shaped pipe jacking machi...
