Description
Technical field
The invention belongs to Tunnel Engineering fields, draining more particularly to a kind of inflation starting formula tunnel suitable for massif tunnel
Road drainage system.
Background technique
It is influenced by complicated geological environment and hydrogeologic condition, the construction in tunnel and operation process still face much at present
Engineering disease problem.Wherein, the water leakage defect in tunnel is exactly the problem of the operation of puzzlement tunnel and maintenance.It seeps for a long time in tunnel
Leak can generate erosion damage to tunnel-liner, and percolating water can also generate emollescence to tunnel surrounding, reduce the strong of country rock
Degree, causes wall rock destabilization to destroy.Tunnel Water Leakage, which drops onto road surface, will cause surface gathered water or icing, influence traffic circulation.Mesh
Preceding drainage measure destroys lining cutting globality larger, and draining range is smaller, and long-term is ineffective, for maintenance cost compared with
It is high.In recent years it is proposed that tunnel siphon drainage technology, arranges that convenient, water-collecting capacity is strong with drainage hole, cuts drainage effect
Well, the advantages that engineering construction speed is fast, however in the engineering using tunnel siphon drainage method, it needs to keep at the top of siphon pipe
Certain vacuum degree, but due to the gas being dissolved in water can be precipitated under negative pressure, outside air penetrates into siphon pipe etc.,
Part siphon pipe usually causes vacuum degree to decline because air is accumulated in pipe, and part siphon pipe can temporarily be in and stop working
State will lead to that siphon drainage is difficult in maintenance or even entire siphon drainge system if siphon pipe is in for a long time and arrheas state
It interrupts, siphon starting becomes abnormal difficult.In addition, tunnel siphon drainage technology generally uses diameter 4mm siphon pipe below, rainbow
