Abstract
It closes to divide the utility model discloses a kind of speciality high risk mountain tunnel and repairs structure, including left line main tunnel (10) and right line main tunnel (8), pass through lateral service channel (9) connection between left line main tunnel (10) and right line main tunnel (8), pass through transverse passage-way (7) connection parallel heading (4) on the left of left line main tunnel (10), parallel heading (4) is lower than left line main tunnel (10), and left line main tunnel (10) is lower than right line main tunnel (8).The utility model becomes original two-wire list hole large cross-section tunnel based on the narrow-bore tunnel in single line list hole, leads advanced mode so that more light-gauge perforation is flat, effectively neutralizing construction risk.Laterally using from right line main tunnel be higher than left line main tunnel be higher than parallel heading, it is longitudinal use open roof, unimpeded, effectively neutralizing gushing water, prominent mud risk are drained in work progress.
Description
Technical field
The utility model relates to a kind of conjunction of speciality high risk band perforation parallel heading point repair flat mountain tunnel, vertical section and
Structural shape.
Background technique
With the fast development of China's economic society, the height in the raising of highway, railway infrastructure grade, especially mountain area
The construction of fast railway, highway, building for long mountain tunnel can be more and more；Mountain tunnel can pass through various complicated geologicals
Condition thus constitutes high risk long mountain tunnel.Long mountain tunnel, which generallys use, at present adds horizontal hole and inclined shaft with reality
Existing " long tunnel hand-to-hand fight in tights ", but it is greater than I grade of high risky tunnel of speciality of 14km for length, the draining of inclined shaft counter-slope will increase construction instead
Risk, large cross-section tunnel cross section are easy landslide and are unfavorable for reducing construction risk." long tunnel hand-to-hand fight in tights ", i.e., it is a plurality of oblique by being arranged
Be connected outside well, horizontal hole and Tunnel, full tunnel import and export direction+inclined shaft, cross is wide open sets multiple work surface construction main tunnels, Ci Zhongshi
Work technology has advantage, but the Shortcomings in terms of prevention and control construction risk in terms of accelerating construction progress, as dashed forward in constructing tunnel
Water, prominent mud, inclined shaft due to be counter-slope from the direction to hole, cannot effectively drain, such as soft rock large deformation and landslide, will lead to
It constructs and interrupts in a certain working face.Since main tunnel sectional form is two-wire list hole big cross section, soft rock section is still remained and is collapsed
The risks such as side.When problem above bursts I grade of high risk, live construction personnel, mechanical equipment do not have the route of retreat, exist very
Big construction safety risk.
Summary of the invention
Technical problem to be solved by the utility model is: at present when building long mountain tunnel using " long tunnel is short
Beat " there are problems that construction safety risk, it put down by light-gauge perforation and leads advanced construction, used according to face country rock situation
Wall rock geology situation in front of a variety of advance geology exploration methods and accurate forecast takes targetedly prevention to arrange in construction accordingly
It applies, arrangement and method for construction dynamic adjustment, greatly reduces the risk of tunnel construction, construction safety is controllable.
The technical solution that the utility model is taken are as follows:
A kind of speciality high risk mountain tunnel, which closes, point repairs structure, including left line main tunnel and right line main tunnel, left line main tunnel and the right side
By lateral service channel connection between line main tunnel, left line main tunnel left side passes through transverse passage-way and connects parallel heading, parallel heading
Lower than left line main tunnel, left line main tunnel is lower than right line main tunnel.
Left line main tunnel front end is that section is repaired in main tunnel conjunction in tunnel, and main tunnel conjunction in tunnel, which is repaired section and closed through tunnel, point repairs variable cross-section greatly across crossing
Become two tunnel main tunnels point behind Duan Duoci transformation tunnel section and repair section, a tunnel main tunnel point repairs section and extending to left tunnel line just
Hole, another tunnel main tunnel point repair section and extend to Tunnel Right Line main tunnel.
Intermediate herringbone high, inlet and outlet are low is longitudinally respectively adopted in parallel heading, left tunnel line main tunnel and Tunnel Right Line main tunnel
Longitudinal slope structure.
Parallel heading is lower than Tunnel Right Line main tunnel 0.3-0.6m lower than 1~2m of left tunnel line main tunnel, left tunnel line main tunnel.
It is one-tunnel two-tracks big cross section structure that section is repaired in main tunnel conjunction in tunnel, repairs variable cross-section through tunnel conjunction point and repeatedly becomes across changeover portion greatly
After changing tunnel section, section is repaired in main tunnel conjunction in tunnel becomes two slightly smaller one-tunnel one-track tunnel structures of cross section, i.e. two tunnels are just
Repair section in hole point.
Parallel heading is constructed in advance compared with main tunnel.
The beneficial effects of the utility model are as follows:
This technology uses " big tunnel is small to be beaten ", i.e., original two-wire list hole large cross-section tunnel is become with the small disconnected of single line list hole
Based on the tunnel of face, advanced mode is led so that more light-gauge perforation is flat, effectively neutralizing construction risk.Laterally to adopt convenient for draining
Open roof is used higher than parallel heading, longitudinal direction higher than left line main tunnel with right line main tunnel, unimpeded, effectively neutralizing is drained in work progress
Gushing water, prominent mud risk.Flat lead of this technology perforation accurately verifies front geological condition in advance, has taken and has been directed to for the construction of lower step main tunnel
The precautionary measures of property adjust arrangement and method for construction, effective prevention and control construction risk in time.Single port perforation in this technology tunnel is flat to be led, left line just
Hole, right line main tunnel form flowing water, parallel operations, and each surface construction equilibrium that works carries out.
This division repairs that band perforation in tunnel is flat to lead superstructure the pattern relatively previous more inclined shafts of major long tunnel band and transverse passage-way knot
Configuration formula has advance for I grade of high risky tunnel construction party face of speciality.
Detailed description of the invention
Fig. 1, which closes to divide, repairs speciality high risk mountain tunnel plan view
In figure, 1- penetrates through parallel heading import, the main tunnel import of the tunnel 2-, and section, 4- parallel heading, 5- are repaired in main tunnel conjunction in the tunnel 3-
Tunnel, which closes to divide, repairs variable cross-section greatly across changeover portion, and the tunnel 6- main tunnel, which is divided, repairs section, the transverse passage-way of 7- parallel heading and left tunnel line main tunnel,
