The invention discloses a high-efficiency vertical seepage drainage device for a tailings pond, which comprises a seepage drainage pipe (1) and a connecting pipe (2). The seepage drainage pipe (1) is vertically arranged in the tailings pond and passes through the connecting pipe (2) Connected with the hidden drainage pipe and the drainage chute of the tailings pond or directly lead out of the pond, the seepage drainage pipe (1) consists of a pipe body (3) with a plurality of through holes (31) in the center, and a covering pipe The filter cloth (4) and the fixed net (5) on the outer circumference of the body (3) constitute. The present invention vertically arranges seepage drainage pipes with through-holes on the inner wall and outer covering filter cloths in the tailings dam, so that the tailings are funnel-shaped to discharge seepage at about 45° along the drainage pipes, and the seepage drainage area increases with the accumulation of tailings. Gradually increase, the closer to the seepage pipe, the better the effect, so as to effectively reduce the infiltration line in the vertical direction and ensure the safety of the tailings pond. Compared with the traditional horizontal seepage discharge pipe, the seepage discharge pipe of the present invention is more resistant to pressure and less prone to bending, and can also be used as a horizontal seepage discharge pipe, and can also be used in combination with the horizontal seepage discharge pipe.

The invention discloses a flow-adaptive drainage ditch and belongs to the field of drainage. The flow-adaptive drainage ditch is composed of a water collection tank on the upper layer, a drainage tankon the lower layer and a drain pipe connected with the water outlet end of the drainage tank; the water collection tank and the drainage tank communicate through a series of multiple water guiding holes with the different cross section areas; and the multiple water guiding holes are formed in the bottom of the water collection tank and distributed at intervals in the tank length direction of thewater collection tank, and the cross section areas of the multiple water guiding holes are sequentially decreased step by step in the flow guiding direction of the drainage tank. According to the flow-adaptive drainage ditch, even if the ditch is in the horizontal direction, rainwater in the water collection tank can be taken away rapidly in the large rainfall period while drainage of the small-rainfall or large-gradient ditch is not affected, the situation that water is accumulated because the water collection tank is flat is avoided, and the flow-adaptive drainage ditch has the advantages ofbeing rapid in flood drainage, simple in structure, easy to manufacture, low in cost, convenient to construct, adaptive in displacement and adjustable in mounting; and in addition, a rainwater pipe culvert and a sewage pipe culvert can be vertically laid in the same position, and thus the advantages of occupying the small space and saving investment are achieved.

The capsulation structure includes a base plate with an up surface, a wafer of composite crystal jointed to the up surface, and a radiator setup on back face of the wafer. The radiator includes a shell body for heat elimination and refrigerant. The shell body for heat elimination possesses a bottom heat exchanger, top heat exchanger and a part for collecting refrigerant. Including multiple heat radiating convex poles, the bottom heat exchanger is in use for increasing area of dissipation. The part for collecting refrigerant is connected to the bottom heat exchanger and the top heat exchanger. When carrying out thermolysis circulation inside the shell body, refrigerant can flow to heat radiating convex poles to be vaporized. The shell body for heat elimination and the refrigerant are in use for promoting efficiency of heat conduction of the capsulation structure in order to maintain normal temperature.

The invention provides a sinking type foundation pit dewatering and draining system. The sinking type foundation pit dewatering and draining system mainly comprises water collecting wells, dewateringwells, blind ditches and open ditches. The water collecting wells are arranged at every corner of the foundation pit. The open ditches are formed in the periphery of the bottom of the foundation pit.Adjacent two water collecting wells are connected by one open ditch. The dewatering wells are uniformly formed in the foundation pit according to on-site requirements. The well openings of the dewatering wells are lower than the bottom plate of the foundation pit. The blind ditches extend in a cross shape with the dewatering wells as the centers. The blind ditches extending from adjacent dewatering wells are connected. The blind ditches extending to the periphery of the foundation pit are connected with the open ditches. In this way, a network of crisscrossing ditches is formed. The dewateringand draining system can well solve the problems that draining of the foundation pit is slow and draining is difficult. The draining efficiency is high. The sinking type dewatering and draining systemdoes not influence running of construction machines in the foundation pit. Construction efficiency and continuity can be guaranteed. The invention further provides a construction method and an application method of the dewatering and draining system.
