Drainage method and device for calcium deposits in underground powerhouses

Abstract

The invention relates to a mountain calcium precipitate drainage method and a device thereof for an underground powerhouse. The method comprises the following steps: plastic funnels are arranged below water percolating points of a mountain at the top of the underground powerhouse to receive mountain percolating water; a plurality of splayed region drainage pipes are arranged in upper space of the underground powerhouse, and slotted holes are formed in the region drainage pipes; hoses connected with the funnels are communicated to the slotted holes of the region drainage pipes; a drainage main pipe with a notch in the upper part is distributed above original discharge ditches on the left and right sides of the underground powerhouse, and a blockage indicator is mounted on the drainage main pipe at the same time. The device comprises receiving devices arranged below the water percolating points of the mountain; water outlets of the receiving devices are communicated to the inclined region percolating water drainage pipes positioned below the receiving device through connecting pipes; the drainage main pipe used for collecting percolating water is arranged below water outlets of the drainage pipes; a blockage indication device is arranged on the drainage main pipe. The method and the device have the advantages that the probability that blockage occurs in the pipes can be reduced advantageously, the lengths of the drainage pipes are reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to a method and a device for drainage of calcium precipitates in underground powerhouses. Background technique [0002] At present, the drainage method for water seepage (including acidic water and precipitates) above the main building and other arches of the underground powerhouse of the street power station is that each leaking water point is directly led to the drainage ditch on both sides by a drainage pipe, and the leakage of the mountain The water point interface is basically seamlessly connected with the mountain with professional anti-seepage material (similar to hummingbird’s nest). This engineering measure of drainage and drainage has the following problems: (1) Since each drainage pipe and the mountain seepage The water point interface is seamlessly connected. Once the drainage pipe is blocked, it needs to be handled by a professional team, which will cause inconvenience to daily maintenance; (2) The drainage pipe is fi...

[0002] At present, the drainage method for water seepage (including acidic water and precipitates) above the main building and other arches of the underground powerhouse of the street power station is that each leaking water point is directly led to the drainage ditch on both sides by a drainage pipe, and the leakage of the mountain The water point interface is basically seamlessly connected with the mountain with professional anti-seepage material (similar to hummingbird’s nest). This engineering measure of drainage and drainage has the following problems: (1) Since each drainage pipe and the mountain seepage The water point interface is seamlessly connected. Once the drainage pipe is blocked, it needs to be handled by a professional team, which will cause inconvenience to daily maintenance; (2) The drainage pipe is fixed against the mountain and led to the ground drainage ditch. Due to the irregularity of the mountain surface , the drainage pipe is long (more than ten meters in length), and the mountain precipitates brought out by the leakage water point are easy to accumulate in the depression or turning of the drainage hose to cause blockage, which makes the drainage pipe useless; (3) due to the seepage of the mountain There are too many water leakage points (note: there are more than 2,000 drainage pipes in the underground factory building on the street, of which there are nearly 800 drainage pipes on the roof of the main factory building), which has caused great inconvenience to daily inspection, maintenance and dredging; ( 4) Due to the instability of water seepage in the mountain body, many original seepage water points are blocked by the precipitates inside the mountain body, and the seepage water points are transferred, resulting in new seepage water points, and the drainage pipe loses its original function, resulting in waste
