Abstract
The utility model discloses a bottom plate water drainage pumping device which comprises a water pumping pipe extending into a bottom plate drill hole and made of a seamless stainless steel pipe, an annular drainage siphon pipe arranged at the exposed end of the water pumping pipe and connected with the water pumping pipe through a connection joint, and a valve. Multiple water pumping holes are spaced in the water pumping pipe, a one-way water separation piece is arranged in the water pumping pipe, rubber water blocking rings containing an expanding agent inside are sleeved on the outer wall of the water pumping pipe at an interval, a sealant is arranged between the outer wall of the tail end of the water pumping pipe and the inner wall of the drill hole, and the annular drainage siphon pipe connected with the water pumping pipe is externally connected with a servo pump and a water storage tank. According to the device disclosed by the utility model, water in a bottom plate gap is pumped out through the sealing fluid siphon principle so as to prevent the bottom plate water from softening the bottom plate rock stratum and enhance the stability of the bottom plate surrounding rock; meanwhile, the water yield is effectively controlled through the valve, so that the drainage siphon pipe is always filled with water for sure, and the air is prevented from entering the bottom plate drill hole to weather the rock stratum. The device disclosed by the utility model has the advantages of simple structure, low cost and easiness in construction, and is reliable and effective.
Description
Technical field
The utility model relates to a kind of Floor water drainage exhaust device, is particularly useful for the drainage pump drainage of cranny development country rock in mine, tunnel, underground construction, soft surrounding rock and infiltration country rock Floor water.
Background technology
In mine, tunnel, underground construction, often can run into cranny development country rock, weak surrounding rock and infiltration country rock, country rock contains obvious weak intercalated layer, argillization interlayer, all kinds of structural plane, and all kinds of composite construction.Wherein, have strong dilatancy and efflorescent feature containing mud stone interlayer soft surrounding rock, and when water and dynamic pressure acting in conjunction, mud stone is met after water very easily argillization, often follows country rock infiltration, and moist matter is soft, and tunnel easily produces the phenomenons such as pucking.When this class surrounding rock is taked base plate anchoring support mode, base plate anchor pole sets difficulty and is difficult to form effective anchored force, meanwhile, after generally taking supporting measure, still there will be pucking and roadway floor cracking under infiltration condition, affects tunnel and uses and keep the safety in production.For this kind of situation, need to design a kind of Floor water drainage exhaust device, Floor water guiding is discharged, thereby prevent that base plate absciss layer district ponding from softening country rock, prevention and minimizing pucking.This device is simple in structure, easily construction not only, can also reduce support cost, effectively increases surrounding rock stability.
The content of utility model
Technical problem: the purpose of this utility model is the deficiency overcoming in prior art, provide a kind of simple in structure, cost is low, easy construction, draw water Floor water drainage exhaust device effective.
Technical scheme: floor crack water suction and pumping device of the present utility model, comprise and stretch into the base plate inner drinking-water pipe of holing, servopump, on described drinking-water pipe outer wall, be interval with some card and suction eyes, drinking-water pipe pipeline section junction is set with the rubber water-resisting ring that includes expansion agent, in drinking-water pipe, be provided with unidirectional water proof sheet, exit outer wall and the drilling orifice inwall of drinking-water pipe are filled with fluid sealant, the end of drinking-water pipe outlet is connected with ring-type drainage syphon through jointing, the siphonal other end of ring-type drainage is connected with the entrance of servopump through valve, servo delivery side of pump is in flexible pipe is connected to tank, described drinking-water pipe is made by gapless stainless steel tube.
In described unidirectional water proof sheet, be provided with and can unidirectionally open and closed eccentric pin shaft; Described suction eye is perpendicular to drinking-water pipe tube wall, and each cross section of tube wall is only for punching; Described servopump is voltage stabilizing self-regulation pump.
Beneficial effect: the utility model has taken into full account the Comprehensive Characteristics of cranny development country rock in mine, tunnel, underground construction, weak surrounding rock and infiltration country rock, a kind of Floor water drainage exhaust device is provided, by law of connected vessels and fluid-encapsulated siphon principle, the water in floor crack is extracted out, stop soft rock supporting system aquation to lose efficacy, by the valve arranging, effectively control water yield simultaneously, guarantee to have reliability, safety and the permanence of soft rock supporting system under crevice water condition.It is simple in structure, with low cost, and easily construction, reliably effective.Tool has the following advantages:
1) drinking-water pipe pipeline section junction is set with the water-ring that includes expansion agent, can be according to rock seepage situation, ponding is effectively intercepted, the ponding that prevents different rock-layers flows out along hole surface, simultaneously, between drinking-water pipe exit outer wall and drilling orifice inwall, be filled with fluid sealant, play the positive role of water blockoff efflorescence prevention;
2) the siphonal other end of ring-type drainage is connected with the entrance of servopump through valve, can effectively control the water yield and prevent that outside air from entering boring, weathered rock formation;
3) in drinking-water pipe, be provided with unidirectional water proof sheet, can prevent that the water of managing internal upper part collection from flowing to bottom, in order to avoid rock stratum, bottom ponding when long expands, ftractures after soaking;
4) the external servopump of ring-type drainage syphon is voltage stabilizing self-regulation pump, can, according to drawing water inner pipe water pressure automatic regulating switch, form the energy-efficient circulation of drawing water.
