Reinforced concrete jacking pipe and processing technology thereof

Abstract

The invention discloses a reinforced concrete jacking pipe and a processing technology thereof, and belongs to the technical field of pipe processing. The reinforced concrete jacking pipe comprises areinforced concrete jacking pipe main body, and a reinforced anchor rod, an outer reinforced ring and an inner expansion reinforced ring are respectively arranged in the reinforced concrete main body.According to the reinforced concrete jacking pipe and the processing technology thereof, due to the designed structures such as a connecting insertion pipe, an insertion type mounting groove, an elastic connecting piece, a first bridge type sealing fin and a second bridge type sealing fin, under the mutual cooperation of the second bridge type sealing fin, the first bridge type sealing fin, the elastic connecting piece and the like, when two adjacent reinforced concrete jacking pipe main bodies are butted, As the outer diameter size of the side edge of the second bridge type sealing fin is far smaller than the inner diameter size of the insertion type mounting groove, the butting work is made smoother, the construction difficulty is reduced, the construction efficiency of workers is effectively improved, and the sealing performance between the two adjacent reinforced concrete jacking pipe main bodies can be improved. And the stability between the two adjacent reinforced concrete jacking pipe main bodies can also be improved.

Description

technical field [0001] The invention belongs to the technical field of pipe processing, and in particular relates to a reinforced concrete pipe jacking and a processing technology thereof. Background technique [0002] Pipe jacking technology is a non-excavation pipe laying construction technology used in municipal construction. Its advantages are that it does not affect the surrounding environment or has little impact, the construction site is small, the noise is low, and it can work deep underground. Pipe jacking technology has incomparable advantages, but the pipe jacking technology also has disadvantages, such as long construction time and high project cost. [0003] Reinforced concrete pipe jacking is a kind of sewage pipe that is made of cement, steel bars, sand, stones, etc. as raw materials and mixed with a centrifuge. It is mainly used for drainage tasks such as urban rainwater, sewage, or farmland irrigation and drainage. It is a municipal construction project. Th...

Problems solved by technology

[0005] The purpose of the present invention is: in order to solve the currently used reinforced concrete pipe jacking process, there are still some deficiencies in the construction process, because the side end surface of the reinforced concrete pipe jacking is usually designed as a plane structure, resulting in The resistance encountered is relatively large, and when the reinforced concrete jacking pipe is docked with the installed reinforced concrete jacking pipe, because the diameters of the two are the same, and because the deviation of the lower range is prone to occur during the insertion process, the butt joint Due to the problem of difficult work, a kind of reinforced concrete pipe jacking and its processing technology are proposed
