Abstract
The invention discloses a method for draining water gushing from a wall during mine shaft construction, belonging to the mine shaft wall construction technology. The method is characterized in that a cutoff trench is installed on a shaft wall having a vertical depth of 380m; a water tank is installed on the shaft wall below the cutoff trench; a submersible pump is installed in the water tank and is communicated with the cutoff trench via a pipeline; gushing water captured by the cutoff trench is introduced to the water tank by the submersible pump; the water tank is communicated with a 157mm water supply pipeline of the shaft wall; the 157mm water supply pipeline of the shaft wall is utilized to drain water; and the purpose of one-time opening long-time drainage can be realized by adjusting an outlet gate valve of the 157mm water supply pipeline of the shaft wall. The method has the following beneficial effects: the defects of the technology of introducing water to a hanging scaffold water tank in the traditional method are overcome; the construction speed of shaft sinking is improved; and the method is simple, practicable, safe, reliable and practical, is low in cost, and has obvious economic benefits.
Description
Technical field
The present invention relates to mine borehole wall construction technology, specifically is the water discharge method of borehole wall trickle during a kind of mine vertical shaft is built.
Background technology
In the mine vertical shaft was built, along with the constantly pick down of pit shaft, a top table soil section one-tenth well section borehole wall water yield increased gradually, borehole wall trickle and meet a stubble seam water burst, the about 55m of water yield
3/ h.Because of water yield is bigger, brought a lot of difficulties to construction, cause construction speed slow, the borehole wall becomes the well impression quality relatively poor, and constructor's operating environment is abominable.Traditional water discharge method is to adopt the wire rope suspensioning drainage pump, and water is caused the water discharge method of hanging scaffold water tank, and the drawback of this kind method is that the loss of drainage plant accessory is very big, has had a strong impact on borehole wall construction quality.
Summary of the invention
For solving the deficiency of above-mentioned prior art, the invention provides a kind of borehole wall and install the method that submersible pump is stopped borehole wall trickle, submersible pump and water tank are installed on the borehole wall, realized the safe, reliable of draining.
The present invention adopts following technical scheme to realize: the water discharge method of borehole wall trickle during a kind of mine vertical shaft is built, cutoff trench is installed on the borehole wall, water tank is installed on the borehole wall below the cutoff trench, submersible pump is installed in the water tank, submersible pump is communicated with cutoff trench with pipeline; Utilize submersible pump that water burst that cutoff trench cuts is imported water tank, water tank is communicated with borehole wall supply channel; Utilize the draining of borehole wall supply channel,, realize once opening long-term draining by regulating the Water gate valve that of borehole wall supply channel.
The invention has the beneficial effects as follows: said method has solved the deficiency of traditional hanging scaffold water tank technology that water is caused, and has improved the speed of application that pit shaft is dug block downwards, and simple and easy to do, cost is low, safe and reliable practicality, remarkable in economical benefits.
Description of drawings
Accompanying drawing is a schematic diagram of the present invention.
Among the figure: 1, the borehole wall, 2, cutoff trench, 3, anchor pole, 4, suspension rope, 5, submersible pump, 6, water tank.
The specific embodiment
As shown in drawings, cutoff trench 2 is installed on the borehole wall 1 of vertical depth 380 m, installation is used to hang the anchor pole 3 of submersible pump 5 usefulness on the borehole wall below the cutoff trench, and submersible pump 5 usefulness suspension ropes 4 are suspended on the anchor pole 3.Water tank 6 is installed on the borehole wall below the cutoff trench, and water tank 6 usefulness anchor poles are fixed on the borehole wall.Submersible pump 6 places water tank 6, and submersible pump 5 usefulness pipelines are communicated with cutoff trench 2; Utilize submersible pump 5 that cutoff trench 2 water burst that cuts is imported water tank 6, water tank 6 is communicated with the borehole wall 157 mm supply channels; Utilize the borehole wall 157 mm supply channel drainings,, realize once opening long-term draining by regulating the Water gate valve that of the borehole wall 157 mm supply channels.
Be scattering into the water yield of meeting head on less than 1 m3/h through facts have proved with this kind method, for the pit shaft pick build safety, fast, good quality project created condition, guaranteed block wall quality and programming.Make construction speed advance to 36 hours one moulds by 72 hours one original moulds.Stop because top becomes well section borehole wall trickle to be blocked, reduced borehole wall trickle, improved the borehole wall and become the well quality, stopped the phenomenon of honeycomb, pitted skin building the influence of concrete construction.Improve operating environment, met the principle of " dry-well " construction.
