Abstract

The invention relates to a negative-pressure extraction water absorption type reinforcement drainage machine, which comprises a travelling car, a scissor-fork type hydraulic lifting platform mounted on the travelling car, a negative-pressure extraction water absorption device, a water reservoir, a drainage floral tube cleaning device, a rail clamp, two dovetail grooves which are formed in the top of the scissor-fork type hydraulic lifting platform in parallel, a plurality of drainage floral tube devices, a drainage hose, a water collecting device and a T-shaped reversing valve. The drainage floral tube devices are arranged at two ends of the dovetail grooves; one end of the drainage hose is connected with water outlets of the drainage floral tube devices; the other end of the drainage hose is connected with the water inlet of the water collecting device; the water outlet of the water collecting device is connected with a first water outlet of the T-shaped reversing valve through a pipeline; the water outlet of the T-shaped reversing valve is connected with a water inlet of the negative-pressure extraction water absorption device through a pipeline; a water outlet of the negative-pressure extraction water absorption device is connected with a water inlet of the water tank through a pipeline; the water outlet of the water tank is connected with a water inlet of a high-pressure water pump in the drainage floral tube cleaning device through a pipeline; and the water outlet of the high-pressure water pump is connected with a second water inlet of the T-shaped reversing valve through a pipeline.

Description

technical field [0001] The invention relates to a water-repelling device, in particular to a device for strengthening the water-repelling of the top plate in the excavation of sedimentary rocks in mines. Background technique [0002] In the sedimentary rock layer of the mine, if the excavation roof is argillaceous cemented fine-grained sandstone, this kind of sandstone is relatively hard in the anhydrous section, and the mining support roof is not easy to collapse; The wet and soft sandstone on the roof collapsed, causing a safety accident. When the water content of the sandstone reaches a certain level, the sandstone will become tofu-like. If the water reaches a critical state in the sandstone, it will form quicksand, which cannot be supported at all. [0003] The still water in the roof can be divided into two types, namely bound water and free water. At present, at home and abroad, the drainage of free water in the still water of the roof generally adopts the methods of...
