Description
Technical field
Big constructing structure and method across cavern is laterally extended based on narrow and small underpass the present invention relates to a kind of, belongs to ground
Lower building structure field.
Background technology
Two side-wall pilot tunnel is that Large span cavern excavates a kind of construction method mainly used, but common double -side approach
There is problems with method：One-way construction, construction speed is slower；Traffic organization is limited in hole, particularly logical in existing narrow and small underground
When road laterally extends big across cavern, Large Construction, transporting equipment can not be entered by existing passage, need to depend on small-sized excavating equipment people
Work is excavated and hand haulage's dregs, and traffic organization problem is more notable in construction speed and hole, and construction excavation progress is faster, right
The patency of dregs transportation requires higher.Such as bomb shelter catwalk laterally excavates the antiaircraft cavern of large span, and double -side approach is adopted
Laterally excavated with benching tunnelling method from catwalk after entrance, the excavation of the step top soil body enters blocking channel near feeder connection
Mouthful.
The content of the invention
Slow to solve the construction speed when narrow and small underpass laterally extends Large span cavern, traffic and transport organization is limited
The problem of, big constructing structure and method across cavern is laterally extended based on narrow and small underpass the invention provides a kind of.
The technical scheme is that：It is a kind of that based on narrow and small underpass, laterally enlarging, greatly across the constructing structure of cavern, is wrapped
Include advanced tubule 1, anchor pole 2, supporting steelframe 3, changeover portion 4, the triangle soil body 5, horizontal communication passage 6, the remaining soil body 7；
The front end of advanced tubule 1 is provided with extravasating hole, injection cement mortar before excavating（Reinforcing is played to ravelly ground to make
With the cavern top soil body collapses when preventing from excavating）, excavation cavern's vault is distributed in, direction is consistent with cavern excavation direction；Anchor pole
2 are inserted radially into surrounding rock body along cavern, and supporting steelframe 3 is built in base tunnel both sides when excavating bilateral base tunnel and prevents from collapsing, changeover portion 4
For the bench excavation soil body in the base tunnel of both sides；The triangle soil body 5 is located above the bench excavation construction soil body, at interconnection position
The wide top soil body with horizontal communication passage 6；Horizontal communication passage 6 is located between the base tunnel of both sides；The remaining soil body 7 is located at base tunnel
Above section porch.
The advanced tubule 1 is steel pipe, and the anchor pole 2 is reinforcing bar.
A kind of based on narrow and small underpass, laterally enlarging is greatly across the construction method of cavern, and the construction procedure is as follows：
Step1, the both sides punched in existing passage lay shaped steel temporary support, and set advanced tubule 1；Wherein surpass
The preceding grouting of ductule 1 should be closely knit；
Step2, excavate left and right base tunnel in precalculated position and carry out supporting, preliminary bracing steelframe, the model of gib steelframe 3
Selected according to concrete engineering situation；
Step3, base tunnel start to dig step upwards after being formed, and by step, are excavated to tunnel main tunnel arch position and are formed
Changeover portion 4, and continue to excavate the bigger working face of formation forward；
The remaining triangle soil body 5 in Step4, the top of back cutting changeover portion 4, performs supporting in time；
The vault soil body, the middle part soil body in the range of Step5, excavation changeover portion 4, form horizontal communication passage 6, in cavern con struction
Arch system anchor bolt 2 should be applied in time after middle " three-back-shaped " traffic route for forming many UNICOMs, excavation, in time by arch and abutment wall
Steelframe is connected；
Step6, double -side approach continue to construct forward, at the same time take on the left of bidirectional construction, back cutting around base tunnel section
The remaining soil body 7 to cavern's contour line, in mining process the soil body can blocking channel entrance, using horizontal flexible group of communication passage 6
Traffic is knitted, left side base tunnel dregs is delivered into right side base tunnel entrance by interconnection transports passage, and cavern is uprightly excavated termination
Face is protected using Bolt net and jet；
Step7, double -side approach continue to construct forward, still take bidirectional construction, using interconnection back cutting away from existing logical
The Core Soil vault soil body, the middle part soil body in the range of road abutment wall 6m, if mining process produces dregs, influence traffic can be by step 6 method
Traffic route is designed, protection is performed in time, arch and abutment wall steelframe are connected, the upright excavation face in cavern termination uses anchor net
Spray protection；
Step8, treat to excavate the inverted arch soil body after the completion of related work, form the two side-wall pilot tunnel section of standard.
The beneficial effects of the invention are as follows：
1st, process is conducive to while carrying out and reasonable link, it is to avoid the interference between each operation；
2nd, two-way opened digging is carried out after double side wall UNICOM, is conducive to accelerating construction progress, shortens the duration；
3rd, horizontal communication passage connection double side wall, forms many places interface channel in hole and, there is provided a variety of traffic routes, is conducive to
The flexibility of traffic organization is improved, even if the soil body is excavated during two-way excavation blocks catwalk entrance, can also ensure in-cavity construction
Period traffic is unobstructed.
4th, under catwalk execution conditions, the passage proximate Core Soil soil body presses traditional two side-wall pilot tunnel digging operation face
It is small, construction inconvenience, using the horizontal communication passage back cutting core soil body.
