Description

Inner lining repairing mechanism for rain sewage pipeline

Technical Field

The utility model relates to a drainage pipe's repair technology, concretely relates to rain sewage pipeline inside lining repair body.

Background

The collapse damage of rain and sewage pipelines can be caused by ① aging of used pipes of the original pipelines due to overlong use time and collapse in the pipelines due to reduction of ring stiffness, ② collapse of constructed pipelines due to settlement and extrusion of road surfaces, ③ cross construction finished products can cause collapse of the interior of the pipelines due to incomplete protection of the finished products.

SUMMERY OF THE UTILITY MODEL

The utility model provides a rain sewage pipeline inside lining repair body to solve because some pipeline position are more dark, pipeline distribution is complicated and can't directly excavate the construction and can excavate the construction but the problem that efficiency of construction is low, economic cost is high.

The utility model provides a rain sewage pipeline lining repairing mechanism, which comprises a drill bit, wherein the tail end of the drill bit is clamped with a connecting rod through a sleeve connecting piece, and the other end of the connecting rod is connected with a drilling machine; the drill bit is characterized by further comprising a grouting pipe, a steel pipe and a lining pipe, wherein the steel pipe is connected with the lining pipe and the drill bit, and grouting is conducted between the original pipeline and the lining pipe through the grouting pipe.

Preferably, the sleeve connecting piece is a round rod, grooves are formed in the end faces of the two ends of the round rod respectively, and protruding portions matched and clamped with the grooves are arranged at the tail end of the drill bit and one end of the connecting rod respectively.

Preferably, the groove is quadrangular or hexagonal.

Preferably, the length of the sleeve connecting piece is 1-2 cm.

Preferably, the liner tube diameter is smaller than the outer diameter of the drill bit.

The utility model has the advantages that: the utility model relates to a simple and reasonable under the prerequisite that does not excavate, does not influence other pipeline overall arrangement to less time and lower cost have effectually solved that some pipeline positions are darker, the underground pipeline distributes complicatedly and can't directly excavate the construction and can excavate the problem that the construction efficiency is low, economic cost is high.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in detail with reference to specific embodiments.

According to fig. 1 to 3, the utility model provides a rainwater and sewage pipeline lining repair mechanism, which comprises a drill bit 1, wherein the tail end of the drill bit 1 is connected with a connecting rod 3 in a clamping way through a sleeve connecting piece 2, and the other end of the connecting rod 3 is connected with a drilling machine 4; the drilling device is characterized by further comprising a grouting pipe 5, a steel pipe 6 and a lining pipe 7, wherein the steel pipe 6 is connected with the lining pipe 7 and the drill bit 1, and grouting is conducted between the original pipeline 8 and the lining pipe 7 through the grouting pipe 5.

Preferably, the sleeve connecting piece 2 is a round rod, grooves are respectively formed in the end faces of the two ends of the round rod, and the tail end of the drill bit 1 and one end 3 of the connecting rod are provided with protruding portions which are matched and clamped with the grooves. The groove is quadrilateral or hexagonal. The length of the sleeve connecting piece 2 is 1-2 cm. The diameter of the lining pipe 7 is smaller than the outer diameter of the drill bit 1.

The utility model discloses a working procedure is: 1) determining the depth of a blocked pipeline and the size of a working well, measuring the elevation and the blocking position of the pipeline, and arranging a drilling machine 4 according to the actual situation on site;

2) clamping the tail end of a drill bit 1 with one end of a connecting rod 3 through a sleeve connecting piece 2, connecting the other end of the connecting rod 3 with a drilling machine 4, and placing the drill bit 1 in an original pipeline 8;

3) starting the drilling machine 4, cleaning the blockage in the original pipeline 8, and then drawing back the drill bit 1;

4) the lining pipe 7 and the steel pipe 6 are welded and then connected with the connecting rod 3, the steel pipe 6 is connected with the drill bit 1, the motor 4 is started, and the drill bit 1 pulls the lining pipe 6 into the original pipeline 8 and passes through the original pipeline 8;

5) after the lining pipe 7 passes through the original pipeline 8, cutting off the lining pipe 7 along the original pipeline 8, and plugging a pipeline opening by using expanded concrete;

6) after the expansive concrete is hardened, holes are drilled on the road surface, and cement slurry is injected between the original pipeline 8 and the lining pipe 7 by using the grouting pipe 5.

The utility model discloses can with shortest time and minimum investment, under the condition that does not excavate, does not influence other pipeline overall arrangements, reach due effect, can stop the raise dust that the excavation caused moreover, environmental protection more.
