Description

Tunnel drainage casing pipe for removing crystals and silts and use method thereof
Technical Field
The invention relates to the technical field of tunnel water drainage prevention, in particular to a tunnel water drainage sleeve for removing crystals and silted up substances and a using method thereof.
Background
At present, in a tunnel structure adopting a composite lining in the field of tunnel engineering, a drain pipe is usually laid between a primary support and a secondary lining, and comprises a circumferential drain pipe, a longitudinal drain pipe, a transverse drain pipe, a central ditch and the like, and is used for draining seepage water behind the secondary lining and a waterproof board so as to eliminate water pressure. However, during the operation of the tunnel, the lower part of the drain pipe is usually blocked due to silt and deposition brought by water seepage, as shown in the published literature, "problem of blocking the drain pipe in railway tunnel construction" (technical and market, 2015, vol 22, No. 4, page 80, and 2015, 4 months), which indicates that the tunnel drainage system is susceptible to the influence of silt and calcium crystals to form blockage, and the consequences of water pressure accumulation or water seepage due to cracking of the lining are pointed out. In tunnels constructed in karst development areas, underground water is usually rich in magnesium ions and calcium ions, and crystals are gradually formed at the bottom of water flow to block tunnel drainage pipes.
Because the tunnel finishes being built, the drain pipe is sealed behind the secondary lining usually, can't open lining structure with inspection and clearance drain pipe, so effectual desilting measure is less at present. A conventional countermeasure is to provide an inspection well and a grit chamber in the central gutter, but this can only clean the central gutter portion of the clogging. The local drain pipes on two sides of the lining are cleaned in a high-pressure water and high-pressure air mode, but the range of the drain pipes capable of being cleaned is limited. The measures can not effectively clear the blockage of the tunnel drainage system and restore the drainage capacity.
Aiming at the problem that the tunnel drain pipe is easy to block, some experts propose some methods: for example, published by Zhou et Ozhuo (university of Changan, Master's academic paper, pages 57-60, 6 months 2015), the patent paper "research and treatment suggestion for blocking tunnel drainage pipe by groundwater seepage crystallization in karst region" (university of Changan, Master's academic paper), proposes the measures of adopting chemical irrigation water-proof and chemical irrigation-electric anti-seepage technology, changing drainage gradient, putting carbonic anhydrase bacteria into tunnel drainage pipe, removing blockage by pressurization, and adding scale remover into tunnel. Zhao Zhan et al published patents in the field of clearing crystalline blockages of tunnel drains, such as patent 1 (publication No. CN104196563A, published Japanese 2014.12.10), patent 2 (publication No. CN104196564A, published Japanese 2014.12.10), and patent 3 (publication No. CN104196565A, published Japanese 2014.12.10), which disclose a structure for clearing crystalline blockages by arranging overflow pipes to observe the blockage of the drains, changing the water flow speed to prevent the generation of crystals, arranging spiral shafts in the drains, and the like. The above measures, or the problems of complex structure and incomplete clearing, or short-term effective effect, or the need of changing the structure of the tunnel, or high cost, generally cannot completely solve the problem of blockage of the drainage pipe of the tunnel at present.
