Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] Such as figure 1 As shown, the present invention provides a device for repairing underground pipelines, which includes a conical reamer and a push rod. The mouth extends vertically to the axis of the conical reamer to form a section, on which a first annular stopper protrusion is arranged along the horizontal direction of the reamer axis, and the center of the first annular protrusion is on the reamer axis , the push rod sleeve is set in the tapered re...

Abstract

The invention discloses an underground pipeline repairing device and a repairing method thereof. The underground pipeline repairing device comprises a cone-shaped expanding hole opener and a propelling pull rod. The interior of the cone-shaped expanding hole opener is funnel-shaped. A leakage opening at one side is vertically extended to an axis of the cone-shaped expanding hole opener so as to form a cross section. The cross section, along a horizontal direction of the axis of the expanding hole opener, is provided with a first annular limiting bulge. A circle center of the first annular limiting bulge is positioned in the axis of the expanding hole opener. The propelling pull rod is sheathed in the cone-shaped expanding hole opener. One side of the propelling pull rod is provided with alocking button device. The propelling pull rod drives the cone-shaped expanding hole opener to be moved in a pipe. While the cone-shaped expanding hole opener passes through a collapsed position, thecone-shaped expanding hole opener is capable of extruding a collapsed soil body into the surrounding soil body by using geometrical characteristics thereof and a mechanical principle, and achieving apurpose of repairing a collapsed pipeline.

Description

technical field [0001] The patent of the present invention relates to the field of underground pipeline repair, in particular to an underground pipeline collapse repair device. Background technique [0002] Underground rainwater and sewage pipe network due to the new construction, expansion or reconstruction of the city, the ground topography changes, and the soil accumulation height increases, exceeding the soil pressure that the pipe itself can bear, resulting in deformation of the pipe, and serious collapse of the pipe, affecting the drainage of the pipe. should function. At present, it is known that the repair method for radically eliminating the deformation and collapse of the pipeline is to find out the collapsed position of the existing pipeline through excavation for repair, and then backfill after the repair is completed to restore the original landform. The method of excavation and restoration is not only time-consuming and laborious, but also expensive. How to e...
