Description
Technical Field
The invention belongs to the field of tunnel water prevention and drainage, and relates to a tunnel construction joint water prevention and drainage structure and a water leakage treatment method.
Background
The leakage water is the most common disease in tunnel engineering, and the industry has a saying of 'ten tunnels and nine leaks', and the normal use and driving safety of the tunnel function are seriously influenced by the leakage water in the tunnel.
The existing construction process causes that the water prevention and drainage quality is difficult to ensure, and causes that the problem of water leakage of the tunnel is prominent. The most common treatment at the tunnel lining joints is to place an expanded rubber or water stop at the construction joints. Water stops are placed at the deformation joints, usually in the middle of the lining thickness. However, most of the joints of the tunnel lining are vertical, the water stop belts and the expansion rubber are difficult to install and fix, the defects are common during installation, the expansion rubber is poor in capability of filling small gaps in cast-in-place concrete, and interface gaps are easily formed between the expansion rubber and the concrete, so that the waterproof effect is affected, and particularly when the underground water pressure is increased, underground water can always seep out through the defects. The waterstop and the expanded rubber are arranged in the middle of the thickness of the lining, and if water leakage occurs, subsequent treatment measures are relatively complex. In view of the above, a new method for treating water leakage is needed, which can prevent and treat water leakage at the seam of the tunnel during construction, and replace and repair the waterproof device at the water leakage position during operation.
Once water leakage occurs in the tunnel, the tunnel is generally treated by adopting a blocking and draining combined mode, but in the treatment process, the water is drained at certain places, and the water is blocked at certain places without a uniform engineering practice. The underground water is still in a disordered discharge state after a plurality of tunnels are treated, and a plurality of times of disease repair can be carried out in the later period, so that the repair difficulty is high.
