Description

Guide type high-pressure cleaning structure of recrystalization area highway tunnel drainage system Technical Field The invention relates to a tunnel drainage system, in particular to a guide type high-pressure cleaning structure of a recrystallization region highway tunnel drainage system. Background Tunnel engineering plays an important role in modern traffic infrastructure, and as tunnel length and complexity increase, drainage system design and management becomes particularly critical. The reliability of the drainage system directly determines the operational safety of the tunnel engineering. Generally, the tunnel drainage system mainly comprises a circumferential drainage pipe, a longitudinal drainage pipe, a transverse drainage pipe, a road side drainage blind drain and a central drainage drain on the back of the two liners. The accumulated water behind the second lining is led to the central drainage ditch through the annular drainage pipe, the longitudinal drainage pipe and the transverse drainage pipe, so that the water pressure behind the second lining is reduced, and the durability of the lining structure is improved. The blockage of the tunnel drainage system is mainly caused by sediment and chemical crystal. Underground water behind karst area tunnel secondary liningAndThe content is higher, and the tunnel primary support shotcrete contains a large amount ofIons, after passing through the primary support, form a large amount of carbonate crystals, thereby causing the crystallization blockage of the tunnel drainage system. The blocking of the drainage system crystals is one of the most common diseases in tunnels located in karst areas. The crystallization blockage of the tunnel drainage system often causes the defects of cracking of a tunnel lining structure, water leakage, uplift of a pavement structure, cracking, flashing and the like, and seriously affects the driving safety of the tunnel. And because the tunnel drainage systems are buried, especially the annular drainage pipe, the longitudinal drainage pipe and the transverse drainage pipe behind the two liners, the daily cleaning and maintenance difficulties are extremely high. If the tunnel drain pipe in the recrystallized region is cleaned without adopting corresponding measures, the normal service life is extremely short, the tunnel is usually operated for 3-5 years, and the drainage system behind the second lining is basically invalid. In order to solve the problem of blockage of a tunnel drainage system in a recrystallization area, a great deal of study is carried out by each expert, and the main proposal at present is that firstly, a special material drainage pipe is adopted, secondly, special solution and high-pressure cleaning equipment are adopted for flushing, and thirdly, additive in an initial support is adjusted to be reducedAnd fourthly, a method for generating acidic substances by utilizing the metabolic activity of microorganisms to dissolve or accelerate the dissolution of the crystal plugs. The method has advantages and disadvantages, but the field practical application mainly comprises the second method of flushing the special solution and the high-pressure cleaning equipment. When high-pressure cleaning equipment washes, because the drain pipe is buried secretly, very difficult when wasing, generally need block traffic, dig lining structure, road surface structure and dredge and wash even, the cost is very huge.
