Description
Technical field
The present invention relates to tunnel lining structure, the karst area grown particularly to a kind of subsoil water can
Control the lining structure of substrate vertical deformation.
Background technology
Enter 21st century, railway construction in China high speed development, the above high standard of speed per hour 200km
Quasi-double track railway is built more and more, especially in Southwest Mountainous Areas, and karsts developing area, and circuit show line is by song
The restriction of the many factors such as line radius is big, topographic and geologic complicated condition, Karst Tunnel scale increases sharply.
Grow due to karst and karst water and there is the features such as complexity, multiformity and irregularities, karst of growing up
Tunneling risk particularly operations risks is more and more higher.
In recent years, there occurs some nothings during suitable ten thousand, Shanghai elder brother, the expensive Railway Tunnel operation such as extensively
The water damage event such as the deformation of tiny fragments of stone, coal, etc. railway roadbed, inverted arch protuberance, lining cutting percolating water, cause Railway Design, construction,
Build and the great attention of operation each side.
Tradition double track tunnel lining cutting typically uses the liner structure form of bent wall band inverted arch, such as Fig. 5 institute
Show.Using Concrete Filled as railway roadbed basis on inverted arch, in construction, inverted arch is filled with inverted arch and is separately watered
Build.Arranging Central drain+bilateral ditch in tunnel, Central drain is placed in the obturator on inverted arch.
Underground water discharge path is: country rock → preliminary bracing → draining blind pipe → lateral sulcus → transverse drain → in
Edema with the heart involved ditch, the i.e. water of tunnel structure periphery enter tunnel by preliminary bracing infiltration via draining blind pipe ejectment
Central drain within road structural body, outside final discharge hole.The defect of conventional drainage systems maximum exists
In: within Central drain is located at tunnel structure, main ejectment main ejectment arch wall scope circumferentially under
Water, the hydrops below tunnel inverted arch cannot effectively ejectment.Especially in the close region of ground hydraulic connection,
Under continuous rainfall or rainstorm weather, because of groundwater run off abruptly increase, traditional drainage system often cannot and
Time ejectment in the gutter in tunnel structure body, thus cause level of ground water drastically to raise.At Gao Shui
Under pressure effect, cause inverted arch at the bottom of tunnel or inverted arch to fill protuberance, thus destroy ballast bed structure.
Therefore, optimize liner structure and drainage system, it is ensured that at the bottom of tunnel, draining is unobstructed, reduce tunnel bottom water pressure,
Strengthen tunnel bottom structure ability resistant to pressure, become reduction tunnel, karst area water damage risk, it is ensured that operation peace
Complete in the urgent need to.
Summary of the invention
The technical problem to be solved is to provide a kind of base plate anchoring restricted type tunnel-liner structure
Make, to effectively reduce substrate vertical deformation, increase that liner structure is resistant to pressure and anti-floating ability.
The technical solution adopted for the present invention to solve the technical problems is as follows:
The present invention base plate anchoring restricted type tunnel lining structure, including arch wall preliminary bracing structure, two
Secondary liner structure, waterproof and water drainage system and central row tank, waterproof and water drainage system is arranged at arch wall preliminary bracing
Between structure, secondary liner structure, it is characterized in that: described secondary liner structure includes that arch wall secondary serves as a contrast
Building and base plate, base plate is positioned on substrate screed-coat, and its two ends consolidate with arch wall secondary lining two ends；
Lateral separation and arrange vertical along circuit bearing of trend interval in fundamental rock soil layer below described base plate
Confining part, the lower end of each vertical confining part extends in stable rock-soil layer, and upper end is looked for through substrate
Flat bed is fixing with base plate to be connected.
The invention has the beneficial effects as follows, use vertical confining part to add base plate form and replace tradition inverted arch shape
Formula, can increase base plate bearing capacity, also can increase that tunnel bottom structure is resistant to pressure and anti-floating ability；At the bottom of tunnel
Use base arrangement, it is not required to apply Concrete Filled body, effectively prevent the bent wall band inverted arch of tradition
Lining cutting is filled out owing to subsoil water enters extruding destruction between inverted arch and inverted arch blind by inverted arch construction joint
Fill body, cause track structure to destroy；Using plate structure at the bottom of tunnel, excavation operation is more convenient, overcomes biography
The wayward problem such as lead of system lining types inverted arch foundation excavation curvature；Realize liner structure " external row
Water ", arch wall secondary lining subsoil water behind is not passed through abutment wall and introduces tunnel lateral sulcus, and is introduced directly into the end
The central row tank B arranged under plate, is prevented effectively from rain flood subsoil water in season excessive lateral sulcus drainability not
Pour in railway roadbed enough；Owing to central row tank is positioned under base plate, can guarantee that the smooth and easy of subsoil water all the time
Drain and avoid high hydraulic pressure to cause bottom slab crack to swell.
