Abstract
The utility model relates to a be used for handling stable structure that solution cavity caves in in karst tunnel fills out step, concrete spray layer, concrete arch and forms by supporting I -shaped steelframe, steel pipe grid rack, piling, support I -shaped steelframe and steel pipe grid rack component and strut the bow member, it has the concrete to execute among the steel pipe grid rack to do, the last work buffering of executing of concrete arch is blown sand, concrete arch thickness 30 40cm, it is 20cm to cushion the thickness of blowing sand, dissolve the intracavity delimitation and dissolve chamber profile, dissolve chamber profile and cover one deck concrete spray layer, steel pipe grid rack arranges according to its atress structure in supporting the I -shaped steelframe, and the vault is close with the distribution of hunch foot, and other positions are dredged, this kind of structure can be fine a processing solution cavity difficult problem of collapsing, guarantee the tunnel and be under construction smoothly along excavation face, avoid because the incident that the solution cavity collapses and brings to stable in structure, the construction is simple and convenient.
Description
Technical field
This utility model is related to solution cavity and caves in process structure, especially relate to geological conditions especially complex in the case of one
Plant in Karst Tunnel for processing the rock-steady structure that solution cavity caves in.
Background technology
Karst Tunnel is built, and due to being located in complex geologic conditions, therefore various disasters occur at any time, particularly karst distribution
Location, is likely to during excavation to run into solution cavity and caves in, and then affects the construction of engineering, if process improper it is more likely that
Cause secondary cave in, directly result in overall the stablizing in tunnel.
The presence harm of solution cavity is big, but because the position of solution cavity has difference, solution cavity is of different sizes, and the harm causing is also
Difference, typically encounters solution cavity and caves in, tradition solve method be exactly that direct slip casting is tamped, but the drawbacks of this method precisely due to
Directly tamped with concrete, concrete well and rock mass forms unified surrounding rock structure also can not cannot have self-bearing ability,
It is susceptible to the secondary possibility caved in, the loss that causes is bigger.
Content of the invention
In order to solve Karst Tunnel build in, traditional solution cavity cave in presence structural instability, be susceptible to secondary collapsing
The problem collapsed, devises and is used for processing the rock-steady structure that solution cavity caves in a kind of Karst Tunnel, and this structure construction is easy, structure
Stable, can be very good to solve the difficult problem that solution cavity caves in Karst Tunnel.
This utility model is to be used in a kind of Karst Tunnel processing the rock-steady structure that solution cavity caves in, and is by support i-beam frame
(1), steel pipe gratings (2), landfill step (3), concrete spray coating (61), concrete arch (7) composition；Supporting bow member (10) is by supporting
I-beam frame (1) and steel pipe gratings (2) composition；I-beam frame (1) is supported to be close to country rock (4)；Landfill step (3) applies in support
Under i-beam frame (1)；Supporting bow member (10) is upper to arrange concrete arch (7).
As improvement, in steel pipe gratings, apply concrete；Buffering is applied on concrete arch blow sand；Concrete arch thickness
30-40cm, buffering blows sand thickness for 20cm.
As improvement, molten intracavity delimit molten chamber profile, and molten chamber profile covers a layer concrete spray-up.
As improvement, steel pipe gratings arranges according to its force structure in supporting i-beam frame, and vault and arch springing distribution are close,
Other positions are dredged.
The beneficial effects of the utility model:
1. using the supporting bow member supporting i-beam frame and steel pipe gratings composition, define very strong bearing capacity, have very
Stable structure.
2. speed of application can be increased by landfill step, reduce and apply space, be easy to construct.Mixed in the injection of solution cavity profile
Solidifying soil spray-up, prevents the solution cavity rubble exposing from producing and drops.
3. concrete arch is set on supporting bow member, this is to form a kind of natural arcuation state, can be in order to be formed with rock mass
Overall structure, produces self-bearing ability；On concrete arch, setting buffering is blown sand and can be reduced the solution cavity stone dropping to concrete arch
Destruction.

Specific embodiment
With reference to the accompanying drawings: this utility model be in a kind of Karst Tunnel be used for process the rock-steady structure that solution cavity caves in, be by
Support i-beam frame (1), steel pipe gratings (2), landfill step (3), concrete spray coating (61), concrete arch (7) composition；Supporting bow member
(10) it is made up of support i-beam frame (1) and steel pipe gratings (2)；I-beam frame (1) is supported to be close to country rock (4)；Landfill step (3)
Apply under support i-beam frame (1)；Supporting bow member (10) is upper to arrange concrete arch (7).
As improvement, in steel pipe gratings (2), apply concrete (21)；Buffering is applied on concrete arch (7) and blows sand (8)；
Concrete arch (7) thickness 30-40cm, buffering blows sand (8) thickness for 20cm.
As improvement, in molten chamber (5), delimit molten chamber profile (6), molten chamber profile (6) covers a layer concrete spray-up (61).
As improvement, steel pipe gratings (2) is in supporting i-beam frame (1) according to the arrangement of its force structure, vault and arch springing
Distribution is close, and other positions are dredged.
During Specific construction, first passing through landfill step (3) can increase speed of application, reduce and apply space, be easy to construct.
Then in solution cavity profile (6) gunite concrete spray-up (61), prevent the solution cavity exposing from producing and drop.Using support i-beam frame
(1) and the supporting bow member (10) that forms of steel pipe gratings (2), define very strong bearing capacity, there is very stable structure.In supporting
Setting concrete arch (7) on bow member, this is to form a kind of natural arcuation state, can produce in order to form overall structure with rock mass
Self-bearing ability；Concrete arch (7) is upper arrange buffering blow sand (8) the solution cavity stone dropping can be reduced concrete arch (7) is broken
Bad.
