Description
Technical field
Tunnel is the utility model is related to, more particularly to a kind of tunnel solution cavity and Groundwater Comprehensive administer construction and construction party
Method.
Background technology
In tunnel excavation and liner structure work progress, solution cavity and ground are typically punished using close measure and ejectment measure
Lower water.Close measure objectively has that so the karst water such as disclosed is ground water discharge passage, in draining end
End, water is big, and blindly closure hidden danger is very big, and blocks difficulty, and construction risk is big；Even if temporary transient water blockoff success, then certainly will
Level of ground water is caused to rise, simultaneously as the erratic behavior of karsts developing area, original lithic drainage is destroyed in addition, new water
Grease head highness is difficult to determine, karst water is also difficult to determine to tunnel longitudinal direction coverage, and it is also difficult that anti-hydraulic pressure applies length, thickness
To determine, blindly processing may make tunnel hide under water under high pressure effect, and its abutment wall, inverted arch easily burst, and exist and jeopardize
The traffic safety even hidden danger of passenger's casualty accident.Ejectment measure is to set drain cavern ejectment karst water, and its advantage is draining road
Footpath is clear and definite, solves blindly potential safety hazard caused by closure, but because draining causes new environmental problem unexpected, and it is applied
The work cycle is long, investment is big, big to environment, duration and Investment Influence.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of tunnel solution cavity and Groundwater Comprehensive administers construction, with
Tunnel structure and working security is effectively ensured, and does not influence environment.
Technical scheme is as follows used by the utility model solves its technical problem：
A kind of tunnel solution cavity of the present utility model and Groundwater Comprehensive administer construction, it is characterized in that：Outside tunnel scope from
Earth's surface is set and is communicated in tunnel draining shaft outside the hole at water outlet, and vertical shaft in hole is set below tunnel, and sets connection hole
The draining transverse passage-way of vertical shaft in outer draining shaft, hole, tunnel bottom set the bottom girder across solution cavity, and full envelope water resistant is constructed in tunnel
Lining cutting is pressed, the full anti-hydraulic pressure that seals extends certain length before and after solution cavity.
The beneficial effects of the utility model are, arrange the comprehensive control measures combined using envelope, and it is controllable that tunnel bears hydraulic pressure, can
Implementation is relatively strong；Head height can be effectively controlled, does not change original underground water path, ensures tunnel structure and construction safety
Property, and environment is not influenceed, quick construction is convenient, and investment is smaller.
Brief description of the drawings
This specification includes the following width accompanying drawing of width two：
Fig. 1 is the schematic diagram that the utility model tunnel solution cavity and Groundwater Comprehensive administer construction；
Fig. 2 is the sectional drawing that the utility model tunnel solution cavity and Groundwater Comprehensive administer full envelope anti-hydraulic pressure in construction.
Component and corresponding mark are shown in figure：It is country rock 10, preliminary bracing structure 11, waterproof system 12, first resistant to pressure
Lining cutting 13, waterproof layer 14, secondary anti-hydraulic pressure 15, bottom girder 16, anchor pole 17, draining shaft 20 outside hole, vertical shaft 21, draining in hole
Transverse passage-way 22, fill concrete 30.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
Reference picture 1, tunnel solution cavity of the present utility model and Groundwater Comprehensive administer construction, including in the digging process of country rock 10
The disclosed solution cavity 30 being positioned above.Set outside the country rock 10 and be communicated to draining shaft 20 outside the hole on ground, in country rock
10 lower sections set vertical shaft 21 in hole, and set draining shaft 20 outside connection hole, in hole vertical shaft 21 draining transverse passage-way 22, country rock 10
Full envelope anti-hydraulic pressure is constructed in outside, and the full anti-hydraulic pressure that seals is in the front and rear extension certain length of solution cavity 30.
For the utility model using envelope row's combination technology measure, the external near exit in hole sets draining shaft, is set in hole horizontal
Passage introduces the water into draining shaft, by the full envelope anti-hydraulic pressure of section use before and after solution cavity, underground water is discharged from earth's surface, connects
Enter major groove.Head height can be effectively controlled, does not change original underground water path, structure is feasible, and environment influences small, construction quality
Height, investment are relatively small.Using envelope row to closing, tunnel bears that hydraulic pressure is controllable, and exploitativeness is relatively strong.
Reference picture 2, it is described build tunnel anti-hydraulic pressure include outwards set gradually by country rock 10 preliminary bracing structure 11,
Waterproof and water drainage system 12, first anti-hydraulic pressure 13, waterproof layer 14 and secondary anti-hydraulic pressure 15, the first bottom of anti-hydraulic pressure 13
Connected as one with bottom girder 16, the lower end of waterproof and water drainage system 12 is connected to vertical shaft 21 in hole.
(head is no more than 50m) under normal circumstances, tunnel anti-hydraulic pressure extension 40-50m before and after solution cavity 30, just
The secondary thickness of anti-hydraulic pressure 13 is 50cm, and the secondary thickness of anti-hydraulic pressure 15 is 40cm, and the waterproof layer 14 preferably uses propylene
Hydrochlorate sprays film, substitutes traditional polymer membranes waterproof layer, ensures waterproof effect after just propping up, prevents crossfire before and after underground water
The preliminary bracing structure 11 of reference picture 2 includes the shotcrete layer of covering country rock 10, is embedded in shotcrete layer
Steelframe etc..Also include carrying out grouting and reinforcing to country rock 10 using diameter 42mm slip castings steel floral tube around country rock 10, formed certain thick
The sealing country rock of degree, underground water is avoided to be ganged up along tunnel perimeter hole, karst row gap toward front and rear.
Reference picture 1, a kind of tunnel solution cavity of the utility model and Groundwater Comprehensive are administered construction and constructed as follows：
1. apply draining shaft 20 outside hole；
2. use concrete backfill tunnel top solution cavity 30；
3. apply preliminary bracing structure 11 to construct；
4. apply vertical shaft 21 and draining transverse passage-way 22 in hole；
5. apply waterproof and water drainage system 12, first anti-hydraulic pressure 13 and bottom girder 16；
6. pressing water to examine, the first effect of anti-hydraulic pressure 13 is examined, percolating water such as be present, first handled, reached nothing and ooze
After leakage, then carry out next step；
7. apply waterproof layer 14 and secondary anti-hydraulic pressure 15.
When bottom girder 16 is constructed, underground water introduces draining shaft 20 outside hole by draining transverse passage-way 22 and carries out interim pump drainage, makes
Level of ground water is reduced to bottom girder below 16.
