Spiral winding pipeline repairing device

Abstract

The invention discloses a spiral winding pipeline repairing device. The device comprises a winding machine assembly, and further comprises a grouting assembly and a connecting assembly, wherein the connecting assembly comprises an operation table, a rotating disc, a total backing plate and a supporting assembly, an installation groove is formed in the operation table, the installation groove is internally provided with the rotating disc, the top of the rotating disc is fixedly connected with the total backing plate, and the total backing plate is arranged on the supporting assembly. Accordingto the spiral winding pipeline repairing device, a grouting function is additionally arranged on the basis of an existing spiral winding machine, so that grouting can be carried out between two new and old pipelines after pipe manufacturing is finished through a method of fixing pipe diameter; and in addition, positions of the winding machine assembly and the grouting assembly can be shifted through rotation, so that grouting can be immediately carried out after pipe winding is finished without assembling equipment in a construction site, in this way, timely construction is truly achieved, andconstruction efficiency and repairing speed are both accelerated.

Description

Technical field [0001] The invention relates to the field of trenchless pipeline engineering, in particular to a spiral wound pipeline repair device. Background technique [0002] The construction and renovation of the existing urban pipe network is an unavoidable problem in the process of urban development. After many years of operation of various pipelines, due to corrosion, poor operation and management, etc., various damages and leakages will inevitably occur, which will bring serious economic losses. However, the replacement of new pipelines on the whole line will not only require a huge amount of engineering, but also expensive, The construction period is long. How to restore the safe operation of pipelines economically, efficiently and quickly has attracted great attention at home and abroad, so the research on pipeline repair technology is of great significance.

Problems solved by technology

[0003] Spiral winding pipe lining technology is a complete non-excavation technology dedicated to the repair and renewal of sewage pipelines. It is mainly divided into two processes: pipe expansion method and fixed diameter method. The fixed diameter method is suitable for pipes from DN450mm to DN2500mm. In some pipelines, the strip-shaped PVC profile is wound in a spiral rotation to a new pipe with a fixed diameter, and grouting is made in the gap between the new pipe and the old pipe. The strip-shaped profile used is also passed through during the winding process. The interlocking of the male and female locks forms a tight and seamless new pipe, but because the winding and grouting work are separated, the winding equipment and the grouting equipment cannot be moved and deployed uniformly, which reduces the fixed diameter spiral winding to a certain extent.
