Assembly type pipe jacking construction guide rail device

Abstract

The invention discloses an assembly type pipe jacking construction guide rail device which comprises U-shaped steel plates, steel pipe first half rings and measuring rods, the steel pipes are fixedly connected to the U-shaped steel plates, the number of the steel pipes is two, the two steel pipes are symmetrically arranged, the number of the U-shaped steel plates is three, and the three U-shaped steel plates are sequentially arranged at equal intervals; and twenty symmetrically-arranged screw holes are formed in the U-shaped steel plates, U-shaped holes are formed in the two sides of the U-shaped steel plates, and the measuring rods are connected into the U-shaped holes in a sliding mode. The steel pipes of two length sizes are designed, and the lengths of the steel pipes are 2 m and 3 m respectively; the steel pipes can be fixed in an adjustable mode, the distance adjusting range comprises three sizes which are 700 mm, 900 mm and 1100 mm, the steel pipes are detachably connected, repeated use is convenient, and materials are saved; the longitudinal steel pipes are assembled through connecting plates; and during installation, the U-shaped steel plates are positioned by using the measuring rods in an assisted mode, so that the positioning time is saved, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of municipal engineering, in particular to a prefabricated pipe jacking construction guide rail device. Background technique [0002] Pipe jacking construction is a trenchless construction method, which is a pipeline burial construction technique with no or less excavation. The pipe jacking method is to use the jacking force generated by the jacking equipment in the work pit to overcome the friction force between the pipeline and the surrounding soil, push the pipeline into the soil according to the designed slope, and transport the earth away. After a section of the pipe has been pushed into the soil layer, the second section of the pipe will continue to be pushed in. The principle is to push the tool pipe or the roadheader from the working pit through the soil layer to the receiving pit with the help of the thrust between the main top oil cylinder and the pipeline and the relay room. The pipeline is buri...

Problems solved by technology

[0003] Due to the different outer diameters of pipe jacking pipes in different pipe jacking projects, the length and size of working wells are different, which limits the reuse of guide rails. There is a phenomenon that one pair of guide rails is processed for one pipe jacking project, which causes a lot of waste of materials, large length and size, and transport vehicles. long, and the site will be large after the construction is completed. Therefore, a prefabricated pipe jacking construction guide rail device is proposed.
