Description

Technical Field

[0001] The utility model relates to the technical field of shaft and tunnel construction, in particular to a multi-stage drainage and silt sedimentation prevention device for shaft and tunnel construction. Background Art

[0002] With the rapid development of the mining industry, mine shaft and tunnel engineering has become an indispensable part of production. Especially with the rapid development of mineral resources in my country in recent years, mineral resources have gradually penetrated deeper underground. Therefore, vertical shaft development engineering has become an irreplaceable development method adopted by mines.

[0003] In the construction process of more and more medium-deep vertical shafts, transfer water tanks are used to realize multi-level drainage system auxiliary construction, which has obvious work efficiency. However, each transfer water tank in the drainage system needs to be set up with multi-level sedimentation, which has high construction cost and long construction period. During the operation, a large number of people, materials and machines need to be invested from time to time for dredging and cleaning, which has high maintenance cost and high risk during operation. In addition, if the pump is stopped for cleaning for a long time during the construction process, there will be the risk of flooding the well, which is not worth the loss.

[0004] Because the construction process of the vertical shaft is simple and relatively fixed, adding such a device not only solves the difficulty of cleaning the water tank and avoids safety risks, but also avoids affecting the construction progress and saves costs to the greatest extent.

[0005] Therefore, it is hoped to provide a multi-stage drainage and anti-silt sedimentation device for shaft and tunnel construction to ensure construction safety and progress and achieve the goal of reducing costs and increasing efficiency.

[0006] Therefore, it is necessary to invent a multi-stage drainage and anti-silt sedimentation device for well and tunnel construction to solve the above problems. Utility Model Content

[0010] Furthermore, a cabinet door is rotatably connected to the middle of the front side of the battery cabinet via a hinge, a storage battery is fixedly connected to the interior of the battery cabinet, and the high-pressure fan is electrically connected to the storage battery via a wire.
