Description
Technical field
The present invention relates to deep layer tunneling techniques, more particularly to a kind of interflow of boring construction is regulated and stored moldeed depth layer arched tunnel
And its construction method.
Background technology
Deep layer tunnel of regulating and storing refers to being embedded in Deep underground space（Refer generally to below ground and is more than 20m deep spaces）It is big
Type, super-huge outlet tunnel.Usually waterlogging is easily sent out, is densely populated, underground utilities are complicated, existing drainage system transformation difficulty is higher
Area, deep layer can be set and regulated and stored tunnel.It takes and source diameter flow control is aided with Large Deep tunnel of regulating and storing, be to implement " sponge
City " construction requirements are embodied because of water suiting measures to different conditions, the mitigation of adaptation to local conditions, and drainage waterlogging prevention mark is improved in external built region
Accurate usual way.
Pavement excavation is avoided using deep tunnel engineering control sewage, the destruction to traffic and environment is made to minimize；It avoids and existing
Some subsurface utilities or infrastructure generate conflict；Due to avoiding buildings pile, linear design may be used, without
It is influenced by existing road network.
Effectively to mitigate urban waterlogging and the water pollution in Chicago, the water body environments such as protection Lake Michigan, Chicago reality
It has applied and has collaborated moldeed depth layer tunnel system engineering of regulating and storing, built the tunnel of a long 176km, 2.5 ~ 10m of diameter, 45 ~ 106m of buried depth
Road.Mexico, Paris, FRA, London Times etc. also implement interflow and regulate and store moldeed depth layer tunnel system engineering in succession.
However these is used to collaborate moldeed depth layer tunnel system engineering costly or utilization rate in terms of repairing improvement of regulating and storing
It is relatively low, it is therefore desirable to exploitation convenient for safeguard and can the interflow of space efficient regulate and store moldeed depth layer tunnel.
Invention content
It is an object of the invention to solve efficiently separating for rainwater and sewage, water pollution is utmostly prevented, is ensured high
Effect, reliable, safety maintenance system and service clearance, improve space availability ratio.
To achieve the goals above, the technical solution adopted by the present invention is：
A kind of interflow of boring construction is regulated and stored moldeed depth layer arched tunnel, is that the interflow of class ellipse shield machine construction is regulated and stored type
Deep layer tunnel, by class ellipse shield machine excavate and lining cutting form, structure include deep layer tunnel bulkhead, vertical arc partition wall,
Rainwater cabin, bilge tank and maintenance cabin, ventilation and lighting system, sewage pipe, sewage pipe hanging basket, tool car, garage's access path, row
Vehicle overhauling platform and percolating water promptly store up cabin；The deep layer tunnel bulkhead cross section is class ellipse, in deep layer tunnel bulkhead
Top center is provided with sewage pipe, and is fixed to sewage pipe by sewage pipe hanging basket；The top sewage pipe of bulkhead in deep layer tunnel
Ventilation and lighting system is respectively set in both sides；Tunnel is separated into three cabins by vertical arc partition wall, and two cabins of outermost are
Rainwater cabin, intermediate cabin are bilge tank and maintenance cabin, storage and transportation nacelle of the rainwater cabin directly as rainwater；Rainwater bilge portion is arranged
The height of garage's access path, garage's access path is 300 ~ 600mm, and width is 2 meters ~ 3 meters；Under bilge tank and maintenance cabin
Travelling crane inspection platform is arranged in portion, is tool car on the upside of travelling crane inspection platform, and travelling crane inspection platform underside setting percolating water promptly stores up
Cabin；The height of travelling crane inspection platform is 1 ~ 2 meter.
Garage's access path, travelling crane inspection platform height ensure deep layer tunnel of the urgent percolating water except the two
Bulkhead bottom space forms the urgent storage space of percolating water；500 ~ 800mm is formed in rainwater cabin, bilge tank and the lower section in maintenance cabin
Clear space, ensure that the personnel of garage access path promptly quickly pass through；There is cavity in the inside of the travelling crane inspection platform, is expert at
The both sides of vehicle overhauling platform open up several paddle holes respectively, and paddle hole uses round or ellipse, along the flow side of nacelle
To being uniformly distributed.
Deep layer tunnel bulkhead uses water-proof concrete, and adds barrier coat in its ectonexine, and barrier coat is adopted
With cement mortar waterproof layer, coil waterproof layer, coating waterproof layer, drainage systems waterproof layer, bentonite waterproof material waterproofing layer
It is one or more, when using single waterproof layer as barrier coat when, using two layers or more of waterproof layer as antiseepage painting
Layer.
The sewage pipe uses waterproof material, preferentially uses impervious concrete, and apply impermeable coating in its inside and outside, prevents
It oozes coating and high molecular material is synthesized using pitch；Internal spray inner wall nontoxic type epoxy coating in rainwater cabin, bilge tank and inspection
It repaiies cabin and high molecular material is synthesized using pitch.
The regulate and store construction method of moldeed depth layer arched tunnel of the interflow of above-mentioned boring construction is：
