Description
Technical field
The present invention relates to a kind of shed hole structure using half shallow mining method, be particularly suited for being close to mountain
Landform.
Background technology
Shed hole structure is half Tunnel Engineering of outside open type.In the engineering such as mountain highway, railway
In planning and construction, tradition can be avoided to put the excavation in the excavation of slope for shed hole structure and protected working amount is big
Shortcoming, effectively safeguards ecological environment, is also beneficial to operation security.Shed hole structure typically uses open-cut,
Earthwork evacuation amount and interim side slope protection quantities are the biggest, and often cost is higher, is also unfavorable for water
Soil keeps and the maintenance of ecological environment.
The Chen Shuwang finding Yunnan Communicaiton Planning & Design Research Institute through patent retrieval has one
" shed hole structure of a kind of shallow mining method " (Patent publication No CN 101713294 A) patent of invention,
A kind of method mentioning boring construction shed hole structure, is characterized in that: by peg board formula side wall and batter post, batter post
Between longitudinal binder and connect bottom side wall the coupling beam with inclined column foundation and constitute, use subsurface excavation method from bottom to top
Construction.It mainly the steps include: to excavate lateral pilot tunnel in side wall foundation portion；Use and excavate side from bottom to top
Wall top pile foundation；Mortar flag stone between backfill pilot tunnel scope stake；Pour pile foundation armored concrete；Excavation batter post
Basis, and apply pile foundation top and expose breast boards；Construction batter post and longitudinal binder；Divide bench excavation hangar tunnel
The interior soil body；Remove lateral pilot tunnel supporting, complete side wall breast boards, pour bottom coupling beam；Apply road surface and
Pipe trench structure.
CN 101713294 A patent of invention excavates lateral pilot tunnel, and excavates side wall from bottom to top
Top pile foundation working space is narrow and small, operates relatively difficult, is unfavorable for mechanized construction；Repeatedly excavation disturbance
The soil body, easy unstability between stake；Operation is more complicated, needs to remove workload bigger；Implement difficulty and wind
Danger is relatively big, there is certain potential safety hazard.
Summary of the invention
The present invention provides method and the structure of a kind of half shallow mining method hangar tunnel, has both overcome open cut to execute
Work earthwork evacuation amount and the deficiency that side slope protection quantities is big, big to environmental destruction temporarily, again may be used
To reduce difficulty and the security risk of boring construction, improve mechanized construction degree.
The technical scheme is that: the structure of a kind of half shallow mining method hangar tunnel, this shed hole structure
Surrounded successively by external wall and basis thereof, top board, inner side arch wall, base plate；External wall uses and is beneficial to nature
Ventilate and the introversion of daylighting, window body of wall；Top board uses and ensures twice Guan Bi of structure and the change of overall stress
Section form, its employing oblique section, end, leads to hidden digging structure preliminary bracing, secondary liner structure respectively
Cross in boring will connect reinforcing bar insertion slope body and realize connecting；Inner side arch wall uses tunneling composite lining knot
The liner structure form of structure, i.e. preliminary bracing and secondary liner structure combination；Select respectively according to country rock situation
With grouting with small pipe or anchor pole as tunneling advance support.
Exterior sidewall structure includes using batter post and connection beam.
Top board includes using arched or slab construction.
Inner side arch wall includes using stalk, sloping core or bent wall.
The method of the half shallow mining method hangar tunnel of the present invention, first excavation external wall basis groove,
Construction external wall basis；Construction external wall；Construction top board；Construction grouting with small pipe or anchor pole 4 constructing
Ductule or anchor pole consolidation structure；Divide bench excavation inner side arch wall preliminary bracing structure of constructing；The construction end
Plate；Arch wall secondary liner structure inside construction；Apply road surface, by-wash, greening of banketing.
The medicine have the advantages that and reducing excavation and protected working amount, reducing and ecological ring is broken
While Huai, save operation ventilation, lighting expense use, build up landscape effect preferable, improve operation comfortableness,
And construction organization is simple, convenient, it is simple to mechanized construction, reduce difficulty of construction and risk.
Accompanying drawing explanation
Fig. 1 is the shed hole structure cross-sectional configuration figure of the present invention.
Fig. 2 is the working procedure block diagram of the shed hole structure of the present invention.
In figure, each portion is numbered: 1. external wall basis；2. external wall；3. top board；4. ductule
Slip casting or suspension roof support；5. ductule or anchor pole consolidation structure；6. arch wall preliminary bracing structure inside；
7. base plate；8. arch wall secondary liner structure inside；9. road surface and by-wash；10. banket greening.
Detailed description of the invention
The present invention is further described with enforcement below in conjunction with the accompanying drawings.
As it is shown in figure 1, the present invention proposes the shed hole structure of half boring construction: in external wall uses
Incline, window body of wall, it is simple to gravity-flow ventilation, daylighting, save illumination and ventilate, improve stress condition, and
There is provided ventilation, the window of daylighting for boring construction, improve construction operation environment.Inner side uses boring construction,
Combining lineament, reduce the disturbance to Rock And Soil, operation is simple, reduces the difficulty of boring construction
And risk, it also avoid discarded and projects.
Slope body suitably processes so that top board basis consolidates；Top board uses variable cross-section, and end uses bevel
Face, is connected with hidden digging structure preliminary bracing, secondary liner structure respectively, for easy to connect, by boring
Reinforcing bar will be connected insert in the body of slope.Select grouting with small pipe or anchor pole as tunneling respectively according to country rock situation
Advance support, soil layer or weak surrounding rock can use conduit grouting support, and hard rock can use suspension roof support, little
Conduit or anchor pole outer end casting concrete consolidation；Tunneling divides step construction, with excavation with supporting；In construction
Strengthen construction monitoring, carry out dynamic design and Dynamic Construction；
As in figure 2 it is shown, the present invention proposes the construction procedure of the shed hole structure of half boring construction: first
First excavation external wall basis groove, external wall basis 1 of constructing；Construction external wall 2；Construction top board 3；Execute
Make grouting with small pipe or anchor pole 4 construct ductule or anchor pole consolidation structure 5；In dividing bench excavation and constructing
Side arch wall preliminary bracing structure 6；Construction base plate 7；Arch wall secondary liner structure 8 inside construction；Apply road
Face, by-wash 9, greening 10 of banketing.
