Movable type staged vertical shaft drainage device and drainage method

Abstract

The invention provides a movable type staged vertical shaft drainage device and a drainage method. The movable type staged vertical shaft drainage device comprises an original vertical shaft drainage pipe, a deep well water lifting device and a movable pipeline, wherein at least two gates are arranged on the original vertical shaft drainage pipe in the vertical direction at intervals; a horizontal three-way valve is arranged on one side wall of the original vertical shaft drainage pipe and arranged between every two adjacent gates; the three-way valve is arranged above the water level of accumulated water of a vertical shaft; the deep well water lifting device is suspended in the accumulated water of the vertical shaft through a suspension device; and the lower end of the movable pipeline is connected with the deep well water lifting device, and the upper end of the movable pipeline is connected with the water inlet end of the three-way valve. By means of the movable type staged vertical shaft drainage device and the drainage method, the problems that in the prior art, when the situation that the underground water amount of a shaft is too large, consequently, an underground water pump cannot drain water, and the shaft is flooded happens, an underground drainage system needs to be installed again, and equipment and time cost is increased can be solved.

Description

technical field [0001] The invention belongs to the technical field of well equipment, and more specifically relates to a mobile staged vertical well drainage device and a drainage method. Background technique [0002] During the construction of mine shafts, sometimes there is a situation where the water in the shaft is too large and the water pump in the shaft cannot be discharged, which leads to the flooding of the shaft. And the pipeline is mostly submerged and unusable. [0003] The current practice is to remove the accumulated water in the shaft by reinstalling the underground drainage system; not only does it need to re-purchase the drainage system, but it also takes a lot of time and manpower for installation and construction, increasing equipment and time costs. An effective solution to this problem is currently lacking.

Problems solved by technology

[0004] In view of the above problems, the purpose of the present invention is to provide a mobile staged vertical well drainage device and drainage method to solve the current problem in the prior art that the wellbore is blocked due to the large amount of water in the wellbore that cannot be removed by the downhole water pump. In the case of flooding, it is necessary to reinstall the underground drainage system to increase equipment and time costs, etc.
