Repair device for large-diameter drainage pipes

Abstract

The invention discloses a spliced ​​lining structure for repairing large-diameter drainage pipes, which relates to a device for repairing pipes, and aims to solve the problem of complex construction in the prior art with the aid of large-scale equipment. The main points of the technical scheme include A number of segmented ring linings, a grouting material layer is provided between the ring lining and the drainage pipe, and a grouting hole is provided on the ring lining for the injection of the grouting material; several segmental ring linings are arranged along the axial direction of the drainage pipe, and the adjacent ring linings are installed The ring lining consists of several arc-shaped plates, and the adjacent arc-shaped plates are connected by connecting pieces; the arc-shaped plates are spliced ​​through the connecting pieces to form a ring lining, and the adjacent ring linings are installed by using the mounting piece, so that the ring can be The lining is integrated to form a repair pipe and installed in the drainage pipe, and then the grouting material is injected between the drainage pipe and the ring lining from the grouting hole, and the drainage pipe and the ring lining are solidified together, thereby reducing the possibility of using large equipment and reduce the complexity of construction.

Description

technical field [0001] The invention relates to the field of pipeline repair, more particularly, to a repair device for large-diameter drainage pipelines. Background technique [0002] In the construction, maintenance and management of urban infrastructure, it is often found that underground pipelines are broken, pipeline joints are disconnected, and groundwater seeps, etc., which cause roads to sink or even collapse, thus affecting traffic and normal municipal drainage. . If the road excavation repair technology is used for repair, not only the construction period is long, but also the traffic is affected, and the construction safety and quality cannot be effectively guaranteed. In order to reduce the road excavation and minimize the impact on traffic and society, increase the load resistance of the pipeline, and restore the use function of the pipeline, the use of trenchless repair and repair technology is essential. [0003] The Chinese patent with the authorization ann...

AI Technical Summary

Problems solved by technology

[0004] When using the lined pipe in the prior art to repair the old pipeline, the lined pipe is passed through the old pipeline, and the two ends of the lined pipe are heated and flanged by heat treatment to fix the lined pipe. However, in practical applications, when the old The inner diameter of the pipeline is large. When the old pipeline is long, the weight of the lining pipe is heavy. At this time, it is necessary to use multiple large-scale equipment to assist workers in the construction together, which makes the construction more complicated and needs to be improved.
