Description
Technical field
It is used to pass through large-scale vertical solution cavity group method for tunnel construction the present invention relates to one kind, belongs to a kind of large-scale vertical solution cavity
The Karst Tunnel technical field of group's processing.
Background technology
For the large-scale vertical solution cavity group of Tunnel Passing, scale is big, solution cavity of the Growth Depth more than 30m, and general use is filled
Scheme, is passed through using roadbed form.Hole slag is completely filled out using conventional or using karst cavity around M7.5 mortar flag stones backfill tunnel,
Material usage is huge and can not be transported to working face, and mechanical usage amount is big, and the construction period can not be, it is expected that construction cost and safety wind
Danger is greatly, it is impossible to ensures the completion time of project, considerably increases the difficulty of in-situ processing.
The content of the invention
The technical problem to be solved in the present invention is：There is provided a kind of for passing through large-scale vertical solution cavity group method for tunnel construction,
In large-scale vertical solution cavity group constructing tunnel is punished, using small-sized machine, the equipment such as concrete pump can just be carried out to solution cavity
Processing, the manpower and materials consumption for overcoming prior art to exist is big, and the treatment procedure time is long, and difficulty of construction is big, construction risk
High deficiency, improves Karst Tunnel construction efficiency, reduces cost, reduces security risk.
The technical scheme that the present invention takes is：One kind is used to pass through large-scale vertical solution cavity group method for tunnel construction, and its is specific
Implementation steps are as follows：
Step 1: the rockfall locally lain in solution cavity palisades is removed, and using injection C20 concrete protections.Perpendicular
Section is digged as operation path to solution cavity mouth, and the later stage is used as inspection cavern.
Step 2: large-scale vertical solution cavity mine massively to backfill based on treatment measures, at the vertical molten chamber of face about 48m
More than platform backfilled using C20 concretings, reserve water passage, before concreting periphery palisades are applied with anchor pole insertion
Rock mass, the globality of increase fill concrete and solution cavity wall.
Step 3: being digged in solution cavity face to V grades of surrounding rock supporting type sections and setting up I20a bow members, apply φ 89 and manage
Canopy adds per-fore pouring liquid with small pipe advance support.
Step 4: after 25 meters of excavation supporting construction of getting out of a predicament or an embarrassing situation, returning and doing reinforced concrete to be excavated to tunnel bottom application in solution cavity section
Native plate-girder.
Step 5: arch wall lining cutting is applied, to using C20 concrete backfills in the range of 3m outside lining cutting contour line and rearward blowing
Sand plus waste rubber tire do cushion, backfill height to vault above 2m.
It is preferred that, it is above-mentioned to vertical solution cavity group's circumferential crack and arch solution cavity pre-buried municipal ripple before fill concrete
Pipe, and ejectment is to water passage.
The present invention reserves the technical measures of water passage using fill concrete, by solution cavity section strengthening supporting, molten
Hole section tunnel bottom is crossed over using reinforced concrete beam and plate, reaches quick, the safe purpose to Karst Tunnel processing.
Beneficial effects of the present invention：Compared with prior art, effect of the invention is as follows：
1）Only need small-sized machine, the equipment such as concrete pump can just handle solution cavity, later stage constructing tunnel is improved
Efficiency.
2）Hole slag is completely filled out relative to conventional, water passage is reserved using fill concrete, short construction period saves material,
Improve operating efficiency and foundation bearing capacity requirement can be reached.
3）Using plate-girder Oil pipeline, the security of karst cave treatment is improved.To the pre-buried municipal ripple of the molten chamber of circumferential crack and arch
Line pipe draws bat to water passage, eliminates the hidden danger of the high pressure karst water caused by long-time ponding, makes construction period and put into the future
Operation uses and obtains effective safety assurance.
4）Blown sand behind in vault fill concrete plus waste rubber tire does cushion, can greatly reduced at the top of solution cavity
Destruction of the falling rocks to two lining structures.

Embodiment
The present invention is described further with reference to specific embodiment.
One kind is used to pass through large-scale vertical solution cavity group method for tunnel construction, and its specific implementation step is as follows：
Step 1: the rockfall locally lain in solution cavity palisades is removed, and using injection C20 surface protections concrete 1
Protected, dig section as operation path in vertical solution cavity mouth, the later stage is used as inspection cavern.
Step 2: large-scale vertical solution cavity mine massively to backfill based on treatment measures, at the vertical molten chamber of face about 48m
More than platform backfill is poured using the progress of C20 fill concretes 3, reserve water passage 9, fill concrete 3 pours preceding to periphery
Palisades apply the insertion rock mass of anchor pole 2, the globality of increase fill concrete 3 and solution cavity wall.
Step 3: being digged in solution cavity face to V grades of surrounding rock supporting type sections and setting up I20a steel arch-shelfs, φ 89 is applied
