解决隧道渗漏水问题的关键在于设法保证排水通畅 ,消除隧道衬砌外围水压力 ,改善结构的受力状态 ,防止水对结构的浸蚀破坏 ,“无压防排水法”是通过在衬砌支护内部分层分批暗埋永久“无压排水半管”来实现上述效果的新方法。该方法简便易行 ,能保证隧道永久不渗漏水
The key to solve the problem of seepage water in tunnels is to try to ensure smooth drainage, to eliminate water pressure around the lining of the tunnel to improve the structure of the force state, to prevent erosion of water damage to the structure, “no pressure drainage” is through lining support Internal sub-layer buried in batches of permanent “pressure-free drainage half pipe” to achieve the effect of a new method. The method is simple and easy, can ensure that the tunnel will not leaking water permanently
