Problems solved by technology

In the early stage of leakage, most of them occur inside the tunnel engineering, and it is difficult to detect and repair in time. When the leakage can be observed, the leakage often has lasted for a long time, and the leakage of groundwater has already caused serious damage to the tunnel engineering. A considerable degree of erosion, erosion damage, and even a large head, resulting in the loss of economic and social benefits, and more difficult to repair

Abstract

The invention discloses a tunnel waterproof system. The tunnel waterproof system comprises waterproof plates, wherein each waterproof plate comprises a plate body and a connecting part; a water passing channel is formed in each waterproof plate or adjacent waterproof plates can be combined to form the water passing channel; the water passing channel is used for collecting leaked underground water;the water passing channel is provided with a water passing early warning device; and the water passing early warning device can be used for transmitting water passing information to the outside. Thetunnel waterproof system provided by the invention can be used for carrying out early warning at the early stage of leakage, so that maintenance can be carried out in time, and serious loss caused byscouring, erosion and damage of underground water leakage to tunnel engineering is prevented.

Description

technical field [0001] The invention relates to a tunnel waterproof system. Background technique [0002] In hydraulic tunnel engineering, seepage is one of the most common major hazards. Leakage has serious harm to tunnel engineering, mainly reflected in: the leaked groundwater will dissolve, erode, and scour the concrete project, leading to the destruction of the concrete project, further causing other hazards, and even causing serious losses. The leaked groundwater It will lead to the corrosion of steel bars in reinforced concrete structures, accelerate the aging of concrete structures, and seepage will also cause water loss in water transfer tunnels. [0003] The types of tunnel leakage can usually be divided into three categories: point leakage, such as hole leakage; line leakage, such as deformation joints, construction joints, etc., and surface leakage. There are many reasons for tunnel leakage, such as deformation of surrounding rock, poor design and construction q...
