Emergency equipment for adverse-slope tracking water drainage and silt discharging in tunnel construction

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 [0001] The invention relates to tunnel engineering construction equipment, in particular to an emergency equipment for quickly pumping water and discharging mud through pipelines after the tunnel engineering is submerged by sudden water gushing during the construction process, and is used for emergency rescue. Background technique [0002] Maluqing Tunnel on Yiwan Railway is the tunnel with the largest instantaneous water inflow in the history of railway tunnel construction in my country and even in the world. On January 21, 2006, a serious water inrush accident occurred at the exit of the tunnel. The gushing water filled the excavated tunnel space within 15 minutes and rushed out of the hole. The duration of the water inrush is 140 minutes, and the total amount is about 110×10 4 m 3 . The karst flood caused heavy casualties, all equipment in the tunnel was submerged, and some facilities outside the tunnel were washed away. The direction of the exit of t...

AI Technical Summary

Problems solved by technology

It takes about 2 hours if the personnel are very skilled, which seriously affects the pumping efficiency

[0005] 2. Due to the weight of the manual moving machine, the high-power water pump cannot be used

[0006] 3. Repeatedly dismantling and connecting electricity in a humid environment, there is a great potential safety hazard

[0007] 4. The power of the pumping equipment is relatively large, and high-voltage electricity needs to be connected to the tunnel, and the power supply facilities such as heavy transformers need to move forward with the pumping equipment

[0009] 6. After the tunnel flood disaster, although engineering measures have been taken, there is still a risk of water inrush in the tunnel during the drainage period

It is difficult to ensure the rapid evacuation of personnel and equipment in emergency situations using conventional water pumping methods
