Road crossing sleeve penetrating leading-in vehicle for buried pipeline and using method thereof

Abstract

The invention provides a road crossing sleeve penetrating leading-in vehicle for a buried pipeline. The road crossing sleeve penetrating leading-in vehicle for the buried pipeline comprises three arc-shaped supporting plates, wherein a roller shaft is arranged at each of the front part and the rear part of each arc-shaped supporting plate; the diameter of the roller body of each roller shaft is 50mm, shaft ends are arranged on the two sides of each roller shaft, the shaft ends are arranged in ear plates, and the ear plates are fixedly connected with the outer sides of the arc surfaces of thearc-shaped supporting plates; the two sides of the arc-shaped supporting plates are fixedly connected to with shaft pipes, the side edges of the three arc-shaped supporting plates are sequentially connected with the side edges to form a large arc plate, the shaft pipes of each two adjacent arc-shaped supporting plates are arranged in a staggered mode, and pins are arranged in the shaft pipes in apenetrating mode; and the road crossing sleeve penetrating leading-in vehicle for the buried pipeline is further provided with L-shaped steel plate hooks, the lower ends of the L-shaped steel plate hooks are fixedly connected with the front end parts of the arc-shaped supporting plates, bolt holes are formed in the upper end parts of the L-shaped steel plate hooks, and nuts are arranged in the bolt holes. The invention further provides a using method of the above road crossing sleeve penetrating leading-in vehicle for the buried pipeline. The using method specifically comprises the following steps that the above leading-in vehicle is clamped and sleeved on the head end of a main pipe, and then the tail end of the main pipe is lifted, so that the main pipe is parallel with a sleeve, and themain pipe is advanced in the state that the main pipe is kept parallel with the sleeve. The scheme prevents anticorrosive coating at the surface of the main pipe from being damaged.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to an introduction vehicle for underground pipeline passing sleeves and a use method thereof. Background technique [0002] In the construction of buried pipelines, casings need to be added to protect the pipelines when passing through the road. Most buried pipelines require on-site anti-corrosion with glass cloth and asphalt paint. When the anti-corrosion pipeline passes through the casing, it is extremely easy to damage the anti-corrosion layer. However, during on-site construction, the pipeline is often hoisted by a crane to tilt the pipe, resulting in more casings The contact area with the anti-corrosion layer causes damage to the anti-corrosion layer. This construction method has a great impact on the construction quality and subsequent pipeline operation.

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that in the prior art, when the buried pipe is passed through the casing, the collision or friction between the two pipes is easy to cause the damage of the anti-corrosion layer on the surface of the buried pipe.
