Buried pipeline leak repair drainage positioning device and its application method

Abstract

The invention discloses a draining positioning device for buried pipeline leakage point emergency maintenance. The draining positioning device comprises a slideway, a bearing plate and a bearing trolley. The bearing plate is arranged at the tail end of the slideway, the slideway comprises two parallel sliding rails, and each sliding rail is provided with a sliding groove; the bearing trolley comprises a water pump containing cover and two wheel sets which are welded to the bottom of the water pump containing cover, and each wheel set is installed in the corresponding sliding groove. The invention further discloses a use method of the draining positioning device for buried pipeline leakage point emergency maintenance. By means of the draining positioning device, positioning draining of a draining pump during emergency maintenance is facilitated, the draining efficiency is improved, the labor intensity is reduced simultaneously, and the probability that the water pump is clogged by debris and damaged due to the fact that the water pump is directly put into an operating pit is reduced.

Description

technical field [0001] The invention relates to a maintenance technology for pipeline leaks, in particular to a drainage positioning device for emergency repair of buried pipeline leaks and a method for using the same. Background technique [0002] When repairing and dealing with buried pipeline leaks outdoors, it is necessary to excavate the operation pit for the leak point, and use the water pump to remove the accumulated water in the operation pit. If there are too many, the operation pit is also prone to landslides. The excavation size of the operation pit is related to the diameter of the pipeline and the site conditions. When the water pump is used for drainage of a large operation pit, if there is no mechanical suspension of the pump, the water pump can only be placed on the side of the pit, which is easily affected by debris, gravel, Burial pressure and blockage of sludge and operation pit collapse. [0003] If the water pump is suspended by machinery for drainage,...

Problems solved by technology

[0002] When repairing and dealing with buried pipeline leaks outdoors, it is necessary to excavate the operation pit for the leak point, and use the water pump to remove the accumulated water in the operation pit. There are many, and the operation pit is also prone to landslides

The excavation size of the operation pit is related to the diameter of the pipeline and the site conditions. When the water pump is used for drainage of a large operation pit, if there is no mechanical suspension of the pump, the water pump can only be placed on the side of the pit, which is easily affected by debris, gravel, Burial pressure and blockage of sludge and operation pit collapse

[0003] If the water pump is suspended by machinery for drainage, it is not easy to block the pump body; however, the excavator is usually used to hang the water pump on site, which reduces the efficiency of the excavator, which is a waste of manpower and time.

If the cast iron pipeline is repaired for leaks, it is necessary to drill the leaks. In the case of ash openings, when checking the water level in the pipeline maintenance stage after ash openings, it is necessary to ensure smooth drainage of the drainage pump. Blockage occurs at the bottom of the pump. Cleaning up the clogged drainage pump is a waste of manpower, reduces drainage efficiency, and makes the ash mouth soaked in water.
