Abstract
The utility model discloses a wind pressure drainage device for a long and large tunnel. The wind pressure drainage device comprises an air compressor gas storage tank and a tank body bracket, wherein a high pressure gas inlet pipe opening and a water inlet pipe opening are formed above a tank body of the air compressor gas storage tank 1; a water drainage pipe opening and a pollution discharging pipe opening are arranged below the tank body of the air compressor gas storage tank; and a gate valve is arranged on each pipe opening. A pressure gauge and a pressure releasing pipe are connected to the tank body of the air compressor gas storage tank. The wind pressure drainage device for the long and large tunnel, disclosed by the utility model, has the advantages as follows: a device is provided to change water drainage method of the long and large tunnel, so that the working efficiency is increased and water drainage cost in tunnel construction is reduced.
Description
Technical field:
The utility model relates to the drainage in the tunnel of growing up, and is specially the tunnel blast dewatering installation of growing up.
Background technology:
In the constructing tunnel, the existence owing to crevice water, underground water, covered conduit underground river etc. not only increases difficulty of construction, reduces efficiency of construction; Worsen construction environment,, cause the immersion of ponding country rock like untimely pump drainage; Reduce country rock intensity, tunnel structure is constituted a threat to, bring potential safety hazard.The constructing tunnel draining is a very important ring in the constructing tunnel work.
In the tunnel counter-slope construction more than 1 kilometer, owing to be counter-slope, water can't flow out from the tunnel voluntarily.Counter-slope tunnel drainage commonly used is to utilize one or more water pump series connection that water pump drainage to hole is effluxed water system discharging (meaning as shown in Figure 1) through the tunnel.Multistage draining is taked in the counter-slope draining; Every grade of draining length is about 300 meters; Be per 300 meters a catch basin is set, each catch basin is installed a foul water pump, through foul water pump from first order catch basin pump drainage to the second level catch basin;, to the third level water is expelled to outside the hole step by step by second level catch basin pump drainage.But along with deepening continuously of the constructing tunnel of growing up, draining length strengthens gradually, when length above 1 kilometer; After forming multistage draining; Common meeting is inconsistent because of draining beats at different levels, the reasons such as corrupted of water pump, causes drainage efficiency to reduce, and draining is untimely; Satisfied not the needs of draining, caused ponding in the tunnel and influence safety for tunnel engineering.And in multistage drainage procedure, the frequency that water pump damages is quite high, and when water yield was big in the tunnel, every two-stage catch basin even each catch basin just need send a workman to carry out continual drain operation, make the cost increase very big.
The utility model content:
The utility model will solve provides a kind of tunnel blast dewatering installation of growing up, and changes the operating type that multistage draining is taked in counter-slope draining now.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
The tunnel blast dewatering installation of growing up comprises air compressor air storage tank and tank body support, and air compressor air storage tank 1 tank body top is provided with the high pressure gas air inlet mouth of pipe and water inlet pipe mouth; Air compressor air storage tank tank body below is provided with the draining mouth of pipe and end-of-the-pipe, on each mouth of pipe gate valve is set.
Be connected with pressure meter on the said air compressor air storage tank tank body, and relief tube.
Use the utility model tunnel blast dewatering installation mode of growing up: a catch basin is being set from about 5 meters of tunnel tunnel face; With the ponding in the tunnel; Crevice water, underground water, the construction water ejectments such as cooling water that boring is used like excavation that comprise country rock in the hole to this catch basin, with a small pump with the water pump drainage through this device water inlet to tank body, in the tank body water completely after; Stop into water; Close the gate valve of water inlet pipe mouth, open delivery port mouth gate valve earlier after, open admission valve and utilize high-pressure blast that water punching press in the jar is discharged.High-pressure blast comes from air compressor machine outside the tunnel; Introduce in the tunnel through the high-pressure blast pipeline; Should be supplied to the air pressure gun pneumatic pick of face to use, it is to supply the equipment of tunnel excavation and supporting to use that high-pressure blast mainly acts on, and is applied to originally make the utility model draining just to utilize few part wherein.Because therefore blast, need not adopt multistage discharging much larger than the lift pressure of water pump; The single-stage draining just can be with outside the disposable discharge of water in the hole hole; And utilize the high-pressure blast punching press can water in the jar all be drained, comprise the impurity in the water, have residue hardly in jar.When if the pressure in the pressurized tank is excessive, opens the mouth of pipe that loses heart pressure is reduced; Clear up the regular gate valve of end-of-the-pipe is opened.Whole drainage procedure only needs a workman to monitor, and is easy and simple to handle, is prone to grasp.
The economic effect of the utility model: multistage dewatering installation commonly used, for the little tunnel of displacement, multistage drainage pattern commonly used, the about 5t of each hour draining, about 600 yuan of expense, the maintenance of make-up water pump etc. again, 20 yuan of water effluent costs promptly per ton.If the tunnel water yield is bigger, also need more powerful water pump, then expense is higher; Utilizing the draining of blast dewatering installation mainly is to utilize high-pressure blast; The sub-fraction wind that the used high-pressure blast that draws water just utilizes airduct to divide does not need independent consumes electric power, only needs artificial switch that carries out the gate valve of device; The high pressure pumping device that at present utilizes high pressure to draw water per hour can be discharged 120t; Expense is 360 yuan, adds upper level catch basin pump maintenance expense, about 3 yuan of water effluent cost per ton.Disposable input aspect, multistage draining and need many water pumps, power line and switchboxs, about 5000 yuan of disposable input, and blast drainage pattern, device is simple, easy making process, cost is 1000 yuan of less thaies, and is not fragile, can have enough to meet the need to recycle.Article one, grow up the tunnel according to 100,000 cubes of calculating of draining, adopt the blast draining can practice thrift 1,700,000 surplus yuan.
The good effect of the utility model is: a kind of device is provided, and the change of the tunnel drainage mode that realized growing up has improved operating efficiency, reduces constructing tunnel draining cost.
