Description
Technical field
The utility model relates to the Tunnel Engineering such as highway, railway, rail traffic in civil engineering, in particular in tunnel
Multi-functional lobby water system.
Background technique
Currently, tunnel groundwater treatment principle is generally according to tunnel local environment and underground water sensitivity, formation lithology etc.
Condition takes different disposal strategy.To dredge and preventing lining cutting behind ponding, leak in hole is avoided, hydrostatic pressure is reduced, is reduced
Tunnel bottom level of ground water, the suitable ejectment of the underground water of tunnel-liner behind reduce the seepage pressure and water percolating capacity of lining cutting；To general depth
It buries, medium hydraulic pressure section, uses the principle " based on stifled, limited drainage "；For buried, high hydraulic pressure section, be arranged drainage system into
Row pressure release；Underground water is both needed to introduce in tunnel and is discharged outside hole by the pumping equipment in hole.
Tunnel Engineering water environment can be divided into hole Nei Shui and hole Wai Shui according to the source of water.Hole Wai Shui refers generally to underground water, is
Natural water source other than tunnel is commonly considered as clean after formation subsidence, filtering, unpolluted.Hole Nei Shui
For the various water sources in tunnel, the percolating water, maintenance operation wastewater, cleaning for entering tunnel by crack can be
With water, the snowmelt runoff for fire demand water, by hole flowing backward rainwater (flood) to hole, bringing tunnel by vehicle and other
Water source in all holes；Complex environment in water contact hole in hole, it is considered that be sewage that is dirty, cannot directly utilizing.
Circumferential blind pipe (ditch), longitudinal direction are blind behind by lateral sulcus, central trench, lining cutting for existing double -coil output inner water drainage system
Manage the composition such as (ditch), transverse drain, drain hole.Lateral sulcus and central trench use concrete structure, above cover reinforced concrete cover plate；
Each blind pipe (ditch), drainpipe mostly use punching bellows.
For uniform each ditch water, existing double -coil output hole inner water drainage system is arranged lateral ties and mixes draining, lateral sulcus
Pass through lateral blind pipe intercommunication with central trench, underground water can be discharged into central trench by vertical, horizontal blind pipe outside hole, be emitted into after mixing
Outside hole.
There is the following aspects in above-mentioned existing tunnel drainage system:
1. having a single function, only converge, drain function；
2. polluting environment, underground water and sewage dual disposal in hole outside clean hole；
3. easy silting, lateral sulcus is easy to cause tunnel internal water accumulation cross flow once blocking occurs, and influences to run；It is difficult in maintenance,
Traditional lateral sulcus uses cover board ditch, and cover board longitudinally draws logical setting, and quantity is more, quality weight, and groove dredging is difficult, and maintenance activity needs a large amount of
It opens, resetting cover board；
4. extremely frigid zones are easy to happen frost failure, conventional vacuum ditch need to deepen groove, be arranged double-layer cover plate, between cover board
Thermal insulation material is set, and there are the problems such as at high cost, difficult in maintenance；
5. the lateral sulcus individually set up consumes more building materials.
6. lateral sulcus arrangement occupies more space.
The above problem is not solved effectively for a long time in the art.

Multi-functional lobby water system in a kind of tunnel of the utility model, including it is set to preliminary bracing structure and secondary lining
Longitudinal blind pipe, circumferential blind pipe and splash guard between structure, and the discharge-channel being set in inverted arch Concrete Filled layer, are indulged
It is longitudinally disposed along tunnel to blind pipe, and position is lower than longitudinal construction joint of secondary liner structure, it is characterized in that: the discharge-channel
For the separate type discharge-channel being made of the buried longitudinal hidden pipe of low level, groove type plate ditch and concave well；The concave well is along tunnel
Line longitudinal gap setting, for discharging the groove type plate ditch longitudinal crossing of sewage in hole and being embedded in the middle part of concave well, in concave well
Portion forms U-shaped inner cavity；The buried longitudinal hidden pipe of the low level is located at groove type plate ditch both lateral sides, with the end on concave well longitudinal side wall
Mouth docking, U-shaped inner cavity are connected with the buried longitudinal hidden pipe of two sides low level, and longitudinal blind pipe passes through abrupt slope transverse direction hidden pipe and U-shaped inner cavity
It is connected, underground water converges at U-shaped interior intracavitary outside hole, discharges outward through buried longitudinal hidden pipe.
The utility model has the beneficial effects that realizing that cleaning water source and polluted source separate type discharge, purifies water, reduce
Line clogging probability, energy dissipating draining avoid washing away, and overcome the technical problem not solved effectively for a long time；Construction technology letter
It is single, have a wide range of application, construction risk is small, saves construction material, and protection environment reduces construction, maintenance cost simultaneously.
