Description
Technical field
The utility model is related to shield tunnel technical field, more particularly to the multiple tube loop of a kind of shield tunnel.
Background technology
With the increasing of the expansion and construction density in city, hardened ground rate is more and more high, original reservoir, massif, lake
Pool, fish pond are gradually occupied, and creek section is more and more narrow, and water storage, draining and the natural purifying ability in city weaken significantly, city
Water logging and waterlogging take place frequently.In addition, the high density of population and urban construction density makes city surface source pollution load increase rapidly,
The pollution load of overflow getting worse in rainy season combined system area.Many cities（Especially old town）Because of building dense and upper subway and
The exploitation of synthesis to improve standard of drainage by building shallow underground drainage pipeline and improve a section dirty system to become abnormal
Difficulty, and it is costly.And deep layer outlet tunnel（Finger is embedded in the large-scale outlet tunnel that below ground is more than 30 meters of depth, directly
Diameter is generally 3~10 meters, referred to as deep tunnel）Due to can avoid a large amount of expropriations of land and removing, and it can suitably utilize 30~60m's of city
Deep underground space, thus as the important means of improvement municipal drainage ability at present, and as the inevitable choice of urban development.
In city deep layer outlet tunnel water storage, drainage procedure, chlorine, sulphion in rain, sewage etc. are in different kind organism, chemistry
Corrosive acidic materials can be generated under effect, and deep layer outlet tunnel is gradually deposited and attached to the mud in rain, sewage
Inside（Or inner wall）.Under the effect of such acidic materials long-term corrosion, the damage of outlet tunnel interior wall construction may be caused, opened
It splits and even destroys, seriously affect the normal operation of deep layer outlet tunnel, and then influence the construction of urban flood defence blowdown pipe network.
Due to superiority and the technology maturation of shield method, deep layer outlet tunnel in city is mainly applied using shield method at present
