Abstract
The utility model discloses the structure that a kind of quick solution tunnel collapses, including tunnel（1）, in tunnel（1）It is close to former tunnel inner wall inside the place of collapsing equipped with a section concrete pipe bridge（3）, concrete pipe bridge（3）For reinforced concrete structure, it is internally provided with reinforcing bar（4）；In concrete pipe bridge（3）Top is equipped with one group of grout pipe（2）.The utility model is simple in structure, easy for construction, can fast and effeciently solve the problems, such as collapsing for tunnel, and improve structure overall stiffness.
Description
Technical field
The utility model is related to the structures that a kind of quick solution tunnel collapses, and belong to hydraulic and hydroelectric engineering technical field.
Background technology
According to domestic hydroelectric project development situation, majority engineering distributions, should in the southwests such as river, expensive, Yunnan at present
Regional typical case's geography is characterized as that karst landform is widely distributed, underground karst development, in tunnel operational process, easily forms karst
It collapses, often results in reservoir leakage, large effect is formed to underground structure.For hydroelectric project, karst area subterranean tunnel
Problems to be solved it is more prominent.The processing for karst area subterranean tunnel domestic at present, mostly to relocate or excavation and filling is handled
Based on.But there are following defects for Yi Shang measure:1. processing cost is too big, engineering construction investment is caused to greatly improve；2. construction is difficult
Degree is big, handles quantities and effect has uncertainty.3. the project treatment period is long, project progress is seriously affected.
Utility model content
The purpose of the utility model is to provide the structures that a kind of quick solution tunnel collapses, and are collapsed with quickly solving tunnel
It falls into, improves the strcture safety of underground structure, so as to overcome the deficiencies in the prior art.
What the technical solution of the utility model was realized in：
The structure that a kind of quick solution tunnel of the utility model collapses is that the structure includes tunnel, and tunnel is collapsed in place
Former tunnel inner wall is close to equipped with a section concrete pipe bridge by portion, and concrete pipe bridge is reinforced concrete structure, is internally provided with reinforcing bar；
One group of grout pipe is equipped at the top of concrete pipe bridge.
By adopting the above-described technical solution, the utility model is compared with prior art, the utility model is simple in structure, applies
Work is convenient, and after solution cavity section bottom and part lining concrete are cut and cleared up, C25 pipe of concretes are poured along lining cutting inner wall
Bridge structure, and grouting treatment is carried out to pipe bridge outer wall contact surface, structure overall stiffness is improved, fast and effeciently solves tunnel
It collapses.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the schematic cross section of Fig. 1.
In figure：1- originals tunnel, 2- grout pipes, 3- concrete pipe bridge, 4- reinforcing bars.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples, but not as new to this practicality
Any restrictions of type.
The utility model is constructed by the method collapsed according to a kind of following quick solution tunnels, such as Fig. 1 and Fig. 2 institutes
Show：This method is to be close to former tunnel inner wall inside former 1 place of collapsing of tunnel newly to pour a section concrete pipe bridge 3, pipe of concrete
Bridge 3 is reinforced concrete structure, is internally provided with reinforcing bar 4；In casting concrete pipe bridge 3, at 3 top preset one of concrete pipe bridge
Group grout pipe 2 treats that concrete pipe bridge 3 carries out former 1 place of collapsing of tunnel with concrete pipe bridge 3 by grout pipe 2 after constructing
Consolidation by grouting is handled.The label of concrete used in concrete pipe bridge 3 is higher than the label of concrete used in former tunnel 1；Former 1 institute of tunnel
With concrete marked as C20, concrete marked as C25 used in concrete pipe bridge 3.Grout pipe 2 uses PE plastic tubes, grouting
The caliber of pipe 2 is φ 25mm.Reinforcing bar 4 uses the reinforcing bar of diameter phi 25mm models HRB400.
The structure that a kind of quick solution tunnel of the utility model constructed according to the above method collapses, including original tunnel
Former tunnel inner wall is close to equipped with a section concrete pipe bridge 3 in hole 1 inside 1 place of collapsing of tunnel, and concrete pipe bridge 3 is mixed for reinforcing bar
Xtah Crude Clay structure is internally provided with reinforcing bar 4；At 3 top of concrete pipe bridge equipped with one group of grout pipe 2.
Embodiment
When it is implemented, first then former 1 bottom of tunnel and part lining concrete are cut and cleaned out, along former tunnel
1 inner wall pours C25 concrete pipe bridge 3, and by being preset at the grout pipe 2 at 3 top of concrete pipe bridge to 3 outer wall of concrete pipe bridge
Grouting treatment is carried out with former 1 inner wall contact surface of tunnel, structure overall stiffness is improved, fast and effeciently solves collapsing for tunnel.
Claims (1)
1. a kind of structure that quick solution tunnel collapses, including tunnel（1）, it is characterised in that：In tunnel（1）It is internal tight to collapse place
Former tunnel inner wall is against equipped with a section concrete pipe bridge（3）, concrete pipe bridge（3）For reinforced concrete structure, it is internally provided with steel
Muscle（4）；In concrete pipe bridge（3）Top is equipped with one group of grout pipe（2）.
