Abstract
The invention relates to emergency equipment for adverse-slope tracking water drainage and silt discharging in tunnel construction. The emergency equipment is characterized in that: by the equipment, a train is formed by dismountable vehicle bodies and functional units arranged on the vehicle bodies; and a water drainage system (2), a power supply system (4), a traction system (6) and a logistic guarantee system (7) are arranged from the front side to the rear side sequentially. By the emergency equipment, a large amount of ponding water can be fast and flexibly drained, and silt deposited at the bottom of a tunnel can be diluted and made into slurry by using high pressure wind and is efficiently discharged out of holes by using a pipeline system, so that the working efficiency is greatly improved; and the emergency equipment plays an important role in rescue construction.
Description
Technical field
The present invention relates to tunnel construction equipment, is to draw water fast after a kind of construction of tunnel is flooded by sudden water burst in the process of building and pass through pipeline and discharge mud, in order to the emergency set of rescue specifically.
Background technology
Should ten thousand railway red deer mountain valley with clumps of trees and bamboo tunnels be that China and even world's railway tunnel are built the maximum tunnel of moment water yield on the history.On January 21st, 2006, especially big gushing water accident takes place in tunnel exit.The tunnel space that water burst will excavate in 15 minutes all is full of, and goes out outside the hole.140 minutes gushing water duration, total amount is about 110 * 10
4m
3This time the routed water of karst has caused great casualties, and all devices is submerged in the tunnel, and facility is destroyed by rush of water outside the part hole.The tunnel exit direction is a counter-slope, and positive hole has been constructed 2341 meters when bursting water, and flat leading constructed 3152 meters, and after the tunnel portal water burst stopped, waterline was positioned at tunnel portal, and water is about 18 * 10 in the estimation tunnel
4m
3In order to drain the ponding in the tunnel, search wrecked personnel, to recover construction and produce, unit in charge of construction organizes from the tunnel flat leading with positive hole to carry out the operation of high-intensity pump drainage water simultaneously immediately.
But the engineering properties plumbing work of counter-slope draining brings very big puzzlement, mainly contains following technical barrier:
1. the gradient in red deer mountain valley with clumps of trees and bamboo tunnel is 15.3 ‰, and the water surface whenever moves back 40m (the about 60cm of drawdown) in the hole, the pumping equipment that just must move forward, otherwise the water intake of water pumper just surfaces.Can't continue operation.Each telephone-moving comprises and cut off the electricity supply, artificial telephone-moving, connect operation such as electricity again that pump drainage water conservancy project skill is in counter-slope the tunnel in: the installation water pump → water pipe that the runs in → water pump that draws water → remove moves forward to next position of drawing water → prolongation discharge pipe line → draw water once more.Under the very skilled situation of personnel, take about 2 hours, have a strong impact on the efficient of drawing water.
2. artificial telephone-moving is owing to the reason of weight can not be used high powered water pump
3. under the environment of humidity, tear electricity repeatedly open and connect electric operation, potential safety hazard is bigger.
4. the power of pumping equipment is bigger, needs in the high-tension electricity incoming tunnel, and heavy power supply facilitiess such as transformer need along with pumping equipment constantly moves forward.
5. when drawing water, also must discharge alluvial and reach the mud about 1m, otherwise equipment just can not move forward at tunnel bottom thickness.And these mud are in stream and mould state (semi liquid state semisolid), use the equipment such as loader can't entrucking, have only artificially to use the barreled car, and in transportation, a part flow back in the tunnel again.If with the vehicle shipment, the efficient by at that time takes 2 years.
6. after the water disaster generation is burst in the tunnel,, still there is prominent water burst risk between drainage period in the hole though taked engineering measure.Adopt the in case of emergency very difficult assurance personnel of conventional pumping method, equipment to withdraw fast.
In order to address the above problem, a whole set of emergency set that collection is supplied power, drawn water, moves forward is automatically designed in the middle iron personnel of 11 innings of organizational technologies of group research of technique first.
Summary of the invention
Technical problem to be solved by this invention provides a kind of counter-slope that is used for and follows the trail of that water level draining row becomes silted up, and collection is made slurry, drawn water, power supply and power drive, stringing etc. are the emergency set of one, thereby solve the technical problem of counter-slope tunnel drainage row silt.Pumping equipment, power supply unit, dilution are made equipment such as slurry and be integrated on the train that draws water, can rapidly and efficiently follow the trail of the drawdown reach.
Be used for counter-slope in the said constructing tunnel and follow the trail of the emergency set that draining row is become silted up; It is characterized in that: this equipment constitutes train by each car body that can break and the functional unit that is mounted thereon, and said functional unit is followed successively by drainage system, electric power system, tractive power supply system, logistics support system after by forward direction.
The present invention can have following prioritization scheme: said drainage system, electric power system, lay respectively in order on the platform truck that draws water that connects, the electrical source of power car, and logistics support system is positioned on the logistics service car, and said trailer system adopts the traction power car.
Between said drainage system and electric power system, be provided with pipe distribution system, pipe distribution system is located on the stringing car.
The wheel of the said platform truck that draws water is a standard rule steel wheel, and body framing is a shaped steel, and the front end of body framing and both sides are established the water pump suspension bracket respectively.
Many foul water pumps of said water pump suspension bracket lifting, the delivery port of foul water pump adopts flexible pipe to be connected with the steel pipe front end that is distributed in the platform truck rear portion of drawing water, and the rear end of steel pipe adopts flexible pipe to extend to the stringing car.
On the said platform truck that draws water high-pressure hydraulic pump, water tank and air compressor machine are installed, the delivery outlet of said air compressor machine connects thankss for your hospitality hydraulic giant, and said water tank is connected with giant through high-pressure hydraulic pump.
The said hydraulic giant leading portion of disturbing is provided with the Steel Tube Special that is drilled with plum blossom shape aperture, and Steel Tube Special is connected with the outlet of air compressor machine through flexible pipe.
