Abstract
The invention provides a tunnel drainage system. A railway is constructed usually under the line influence and has to pass through lots of tunnels. After completion of construction of concrete liningsof the tunnels, surrounding fissure water is sealed outside the concrete linings. When defects exist to waterproof layers or lining concrete, underground water can locally seep. According to the tunnel drainage system provided by the invention, a hole is drilled in the position needing draining in a surrounding rock of one tunnel, a drain pipe is placed in the drilled hole, a water inlet of the drain pipe is located at the bottom of the drilled hole, a water outlet of the drain pipe is connected with a starting device, the starting device is placed in a side ditch of the tunnel, and the starting device is fixed to the bottom of the side ditch. The tunnel drainage system can play a role along with rainfall, the water level of the side ditch synchronously goes up, and the tunnel drainage system can stop operating along with the side ditch water level flooding the starting device.
Description
technical field [0001] The invention belongs to the field of geotechnical engineering, in particular to a tunnel drainage system and method. Background technique [0002] Railway construction is often affected by the line, and many tunnels have to be passed through. After the concrete lining of the tunnel is completed, the surrounding fissure water is sealed outside the concrete lining. When the waterproof layer or lining concrete is defective, local groundwater seepage will occur. Seepage from the tunnel wall into the tunnel will have adverse effects on the safe operation of the tunnel: water seepage flows to the road surface causing water accumulation and icing, which will cause vehicles to slip during driving; water seepage erodes the inner surface of the lining, reducing the brightness and visibility of lighting in the tunnel; water seepage damages The tunnel is lined with concrete and the internal structure of the surrounding rock, which shortens the service life of the...
