Problems solved by technology

This construction method cannot determine whether the fusion of the pipes is sufficient after electrification. According to experience, sufficient welding often leads to the failure of pipe welding quality. Subsequent closed water tests lead to many leaks, requiring rework and repair welding, which affects construction efficiency.

Abstract

The invention provides a Krah tube electric hot melting connecting device and method. The Krah tube electric hot melting connecting device comprises an adjusting arm, clamping pieces and a driving mechanism, wherein the two ends of the clamping pieces are respectively provided with two clamping pieces, connecting plates of the clamping pieces are connected with a left arm and a right arm of the adjusting arm respectively, a rack and a gear of the driving mechanism are connected with the left arm and the right arm of the adjusting arm respectively, the two ends, close to each other, of two Krah tubes are clamped through circular clamping rings formed by two semicircular arc plates of the clamping pieces, the driving mechanism drives the left arm and the right arm to drive the two clamping pieces to be close to or away from each other, in the welding process, Krah tube end materials can be fully fused, the welding quality is improved, later repair welding caused by leakage points is avoided, the construction efficiency is improved, and operations are simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of marine foundation protection, and relates to an electric hot-melt connection device and method for carat tubes. Background technique [0002] Carat tube is a high-density polyethylene structural wall tube formed by thermal winding. It uses high-density polyethylene resin as the main raw material, adopts thermal winding poplar technology, and is made of polypropylene (PP) single-wall corrugated pipe as the supporting structure. Special structural wall tubing with high resistance to external pressure. The pipe has excellent installation performance, good flexibility, and can withstand a certain amount of axial line displacement and relative angular displacement. It is an environmentally friendly and safe product with the advantages of light weight, strong pressure bearing capacity, high interface quality, long life, corrosion resistance, high ring stiffness, and convenient construction. It is widely used i...
