Description
Technical field
The present invention relates to Tunnel Engineering technical fields, more particularly, to a kind of vertical karst plugging device in space and envelope
Blocking method.
Background technique
China karst area is widely distributed, and solvable rock stratum distribution area accounts for about the 1/3 of territory total area.With China's economy
Rapid development, development of the West Regions construction flourish, infrastructure construction scale constantly expands, in karst area constructing underground building
Or tunnel (lane) road is excavated, extensive, paroxysmal water bursting factor disaster is easily induced in construction.With increasingly dashing forward for the above problem
Out, have become one of the hot spot of this field to the research of underground engineering water bursting factor disaster.
It in Practical Project, is influenced by geological structure and corrosion, often there are many unfavorable geologic bodies in rock mass, such as fill
The karst or tomography for filling out type, breakdown karst often occur during rich water karst developmentally belt construction causes largely
The scene of water burst, when it is limestone basis that tunnel, which is located at lithology, often limestone develops more karst, in tunnel top and ground
It needs that vertical duct is arranged between face, if vertical duct passes through karst and enters in tunnel, it is easy to leakage phenomenon occurs, it will
Water in karst is brought into tunnel.Existing processing method is all more complicated, and the plugging effect to karst water is not to manage very much
Think, most common method is to carry out grout sealing to karst periphery.
Applicants have discovered that at least there is following technical problem in the prior art:
The prior art has closure process complicated, and the time is long, indirectly increases the risk in construction, while treatment effect
