Nodular cast iron pipeline support device for tunnel

Abstract

The invention discloses a nodular cast iron pipeline support device for a tunnel. The device comprises a fixed base, a supporting seat, at least two arc-shaped pipe clamps and at least two fixed plates. The arc-shaped pipe clamps are arranged in a matched mode, and the edges of the arc-shaped pipe clamps are connected through a first bolt piece. The bottom of one arc-shaped pipe clamp is welded tothe upper surface of the supporting seat. The fixed plates are matched with each other and are fixed to the upper surface of the fixed base. A first strip-shaped fixing hole is formed in each fixed plate. Second strip-shaped fixing holes matched with the first strip-shaped fixing holes are formed in the fixed base in a penetrating mode. The bottom of the supporting seat is in a T shape and is fixed to the fixed base through second bolt pieces. The bottom of the fixed base is provided with arc-shaped elastic cushions. According to the device, the problems that in the prior art, angle iron welding parts are adopted to support a pipeline, the overall stability is poor, and safe operation of the pipeline is affected during long-term use; the position of the pipeline after being fixed is inconvenient to adjust; and the fixed base cannot make effective contact with the tunnel, and therefore the stability further gets worse are solved.

Description

technical field [0001] The invention relates to the field of water supply and drainage and gas pipelines of municipal, industrial and civil construction tunnels, in particular to a ductile cast iron pipeline support device for tunnels. Background technique [0002] In the water supply and drainage pipeline project in the tunnel, the side wall installation method is adopted for the pipeline with a small diameter. At present, the more commonly used installation method is to use the angle steel weldment to support the pipeline, use U-shaped bolts for fixing, and the whole is fixed to the tunnel with anchor bolts side wall. However, the overall stability of the angle steel weldment is poor, which will affect the safe operation of the pipeline during long-term use; and the fixed position of the pipeline is not easy to adjust; the fixed base and the tunnel cannot be effectively contacted, resulting in further deterioration of stability. [0003] Therefore, it is necessary to prov...

Problems solved by technology

[0004] In view of the above technical problems, the purpose of the present invention is to overcome the use of angle steel weldments to support the pipeline in the prior art, which has poor overall stability and affects the safe operation of the pipeline during long-term use; and the position of the pipeline after fixing is not easy to adjust; There is no effective contact between the base and the tunnel, resulting in further deterioration of the stability, so as to provide a pipe with a small diameter that can be effectively fixed during use, and has high stability, and is suitable for tunnels A ductile iron pipe support device for tunnels that can fine-tune the position of the fixed pipes on the sides of different radians
