Description

Technical Field

[0001] The utility model relates to the technical field of water supply pipeline lining repair, in particular to a trenchless lining integral repair structure for a water supply pipeline. Background Art

[0002] As urban infrastructure ages, urban water supply pipeline systems, like other old structures, are increasingly vulnerable to damage. Pipelines are buried deep underground and are invisible, so it is difficult to understand the specific current status of underground pipelines. Sometimes these facilities are damaged without any warning. The result of damage is that the operating water supply pipelines are broken and leaked, which not only causes huge economic losses to the pipeline owners, but also brings environmental problems.

[0003] When repairing the existing water supply pipe, it is necessary to dig up the ground of the water supply pipe to expose the water supply pipe. However, the ground environment of the original concrete water supply pipe is complex and the on-site working environment is small, which causes great difficulties for the construction and is inconvenient for the staff to use. For this reason, we propose a non-excavation lining integral repair structure for the water supply pipe. Utility Model Content

[0006] A trenchless lining integral repair structure for a water supply pipeline comprises a base, two operating pits are excavated on the top of the base, a water supply pipeline body is arranged inside the base, a traction assembly is arranged on the top of the base, a pipeline pressure pump is arranged on the top of the base, a reducer is installed on the top of the base, a HDPE pipe is arranged on the working end of the reducer to penetrate the water supply pipeline body, and a traction pipe is fixedly connected to the other end of the HDPE pipe.

[0007] Preferably, the traction assembly comprises a shell installed on the top of the base, a motor is provided on one side of the shell, a transmission assembly is provided outside the motor, and two first rollers distributed correspondingly are rotatably connected to both sides of the inner wall of the shell.

[0008] Preferably, the two first rollers are movably sleeved with the same lower traction belt on their exteriors, one of the first rollers extends to the exterior of the shell and is fixedly sleeved with a driving wheel, and the bottom of the traction tube can be pulled by the lower traction belt.

[0009] Preferably, two correspondingly distributed second rollers are rotatably connected to both sides of the inner wall of the shell, and the external movable sleeves of the two second rollers are connected to the same upper traction belt. One of the second rollers extends to the outside of the shell and is fixedly connected to a driven wheel. The top of the traction tube can be pulled by the upper traction belt.

[0010] Preferably, one end of the driving wheel is fixedly connected to the output end of the motor, and a same belt is movably sleeved between the driving wheel and the driven wheel, so that the driving wheel and the driven wheel rotate simultaneously through the belt between the driving wheel and the driven wheel.

[0011] Preferably, a support plate is fixedly connected to one side of the shell, and the motor is fixedly mounted on the support plate. The support plate is provided so that the motor will not idle when working.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: when the main body of the water supply pipeline needs to be repaired, the HDPE pipe is first placed in the reducing machine, the reduced HDPE pipe is inserted into the main body of the water supply pipeline, the traction pipe is connected to the HDPE pipe, the motor is started, the driving wheel is driven to rotate, the belt moves, the driven wheel rotates, and the first roller and the second roller rotate at the same time. By rotating the first roller and the second roller at the same time, the upper traction belt and the lower traction belt can be driven to move at the same time, and the traction pipe can be driven to move. By moving the traction pipe, the HDPE pipe can be passed through the water supply pipeline. The inside of the water pipe body is then pressurized using a pipe charging pump to restore the memory of the U-shaped HDPE pipe and make the outer wall of the HDPE pipe close to the inner wall of the water pipe body to form a pipe in a pipe. The above structure is convenient for the staff to repair the water pipe body. There is no need to dig up the ground on the top of the water pipe body to expose the water pipe body, and the water pipe body can be repaired. This avoids the complex ground environment of the original concrete water pipe and the narrow on-site working environment, which cause great difficulties to the construction, and greatly facilitates the use of the staff.
