Abstract
A wall rock drainage water guide device comprises a water guide pipe, a tray, a gasket, a nut and a gate valve, wherein the water guide pipe extends into a drill hole and is formed by connecting a plurality of seamless steel pipes through steel sleeves; the water guide pipe is drilled with a plurality of inclined water guide holes arranged in a cross shape at intervals, the outer wall of the water guide pipe is provided with water blocking rings containing expanding agents at intervals, a hole sealing agent is arranged between the outer wall of the tail end of the water guide pipe and the inner wall of the drilled hole, the exposed end of the water guide pipe is connected with a drainage pipe fixed on a top plate or a roadway side through a gate valve, a U-shaped pipe is arranged at the connection section of the drainage pipe and the gate valve, and the outlet end of the drainage pipe. The utility model discloses a water in communicating vessel principle and the sealed fluid suction with the roof crack is derived, prevents soft rock supporting system hydration inefficacy, controls the water yield effectively and prevents that the outside air from getting into drilling through the gate valve and the U-shaped pipe that set up simultaneously, and the reliability, security and the permanence of soft rock supporting system are ensured to the morals and manners rock stratum under having the crack water condition. The structure is simple, the cost is low, the construction is easy, and the method is reliable and effective.
Description
Technical field
The utility model relates to a kind of country rock water guider, particularly a kind of drainage water guider that is applicable to cranny development country rock in mine, tunnel, underground construction, soft surrounding rock and infiltration country rock.
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, there is strong dilatancy and efflorescent feature containing mud stone interlayer soft surrounding rock, and when water and dynamic pressure affects, argillization very easily after mud stone chance water, often follow country rock infiltration, moist matter is soft, causes anchor cable to set, drilling rod is glued in pneumatic punching, and wet method punching anchoring strength is poor, constructs very difficult.Meanwhile, after this class surrounding rock is taked general supporting, still there will be absciss layer unstability under infiltration condition, collapse and emit each class surrounding rock security incident such as hurt sb.'s feelings, impact is produced.For this kind of situation, need to design a kind of water guide drainage system and method, water in country rock is derived, thereby prevent that absciss layer district ponding from softening country rock, can prevent and reduce roof fall accident, meanwhile, ponding can be puted forth effort basis reliably for anchor pole, cable bolting provide after drawing, and for realizing, the complex condition surrounding rock supportings such as loose crushing country rock, dead-soft rock stratum and infiltration country rock is provided safeguard.This device is simple in structure, easily construction not only, can also reduce support cost, effectively increases surrounding rock stability.
Summary of the invention
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, water guide are effective, country rock drainage water guider that infiltration is dredged.
Technical scheme: country rock drainage water guider of the present utility model, comprise and stretch into boring inner aqueduct, the pallet that is located at successively aqueduct exposed junction, packing ring, nut, gate valve, described aqueduct is formed by connecting through steel bushing sleeve by a plurality of seamless steel pipes, on aqueduct, interval is drilled with some water-guiding holes that cross is arranged that are, on the outer wall of aqueduct, be interval with water-ring, aqueduct exposed junction is connected with and is fixed on the drainage tube that help in top board or lane by gate valve, drainage tube and gate valve linkage section are provided with U-shaped pipe, and the port of export of drainage tube is connected with storage tank.
Described being on the water-guiding hole that cross arranges has downward-sloping interior chamfering; On the outer wall of described water-ring, have a plurality of apertures.
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 top board crevice water let-off gear(stand) is provided, by law of connected vessels and fluid-encapsulated suction, the water in top board crack is derived, stop soft rock supporting system aquation to lose efficacy, by the gate valve and the U-shaped pipe that arrange, effectively control water yield and prevent that outside air from entering boring weathered rock formation, guarantees to have reliability, safety and the permanence of soft rock supporting system under crevice water condition simultaneously.It is simple in structure, with low cost, and easily construction, reliably effective.Tool has the following advantages:
1) stretching into the inner aqueduct being connected through steel bushing sleeve by a plurality of seamless steel pipes of boring can be according to the length of the position adjustments aqueduct at the degree of depth of boring and infiltration water source;
2) on aqueduct, interval is drilled with some inclination water-guiding holes that cross is arranged that are, and water-guiding hole has downward interior chamfering, is conducive to current and flows out;
3) on aqueduct outer wall, be interval with the water-ring that includes expansion agent, can, according to rock seepage situation, ponding be effectively intercepted; Meanwhile, between the outer wall of aqueduct tail end and the inwall of boring, be provided with hole sealing agent, prevent that the ponding of different rock-layers from flowing out along hole wall;
4) between drainage tube and gate valve, establish U-shaped pipe and be fixed on top board or lane is helped, play the positive role of water blockoff efflorescence prevention, drainage effect is remarkable, simple to operate, is easy to construction;
5) gate valve connects aqueduct and drainage tube, can effectively control the water yield and prevent that outside air from entering boring weathered rock formation;
6) each parts such as aqueduct, pallet, nut, gate valve are made by resistant material, effectively prevent corrosion, increase water guide effect and service life.
