Description
Technical field
The utility model relates to tunnel lining structure, in particular to one kind applies to underground water development location or karst area
Tunnel-liner and drainage system.
Background technique
Come into 21st century, railway construction in China high speed development, the above high standard double track railway of speed per hour 200km is built
More and more, especially in Southwest Mountainous Areas, karsts developing area, and route show line, by sweep, big, topographic and geologic complicated condition etc. is more
The restriction of kind factor, Karst Tunnel scale increase sharply.Since karst and karst water development have complexity, diversity and random
The features such as rule property, it is higher and higher that Karst Tunnel of growing up builds risk especially operations risks.
Through investigating, both wired water damage was broadly divided into two classes:
(1) inverted arch filling, which is floated, deforms.Its construction in layer bring construction joint for showing predominantly tunnel bottom structure is in hydraulic pressure
Deformation, expansion under effect.
1. code requirement inverted arch should be separated with inverted arch filling and be poured.This engineering method forms construction joint between inverted arch and filling,
But underground water penetrates into inverted arch by inverted arch circular construction joint and fills bottom, and about 3~4m head can lead to filling and float.
2. in practice of construction, to prevent railway roadbed construction surface from being destroyed by Construction traffic, inverted arch filling often uses placement layer by layer
Mode, railway roadbed construct before placing inverted arch fill surface layer (or regulating course) thickness about 0.2~0.4m, it is only necessary to 0.5~1m
High head can lead to filling surface layer and float, and then railway roadbed is caused to deform.
3. ballastless track bed is to road bed board and inverted arch fill surface using the connectionless way of contact, there are construction interfaces, right
It is more significant in the sensibility of tunnel bottom infiltration, often also there is " off-seam " lifting phenomenon and wear phenomenon, under the action of water, disease
Evil feature is particularly evident.It is very poor to foundation deformation with the huge stiffness difference of tunnel structure, deformation and track structure
Adaptability be further exacerbated by tunnel bottom water evil to the adverse effect and difficulty of governance of operation security.
(2) liner structure especially inverted arch strain cracking.
1. limited by vertical, the circumferential blind pipe and abutment wall drain hole drainability that are arranged in tunnel, after work drainage system by
Physical (silt, fine grained deposition are silted up), chemical type blocking (soluble matter is precipitated, concrete and slurry reaction residue condense)
Etc. reasons will all cause impeded drainage, hydraulic pressure change dramatically leads to liner structure cracking failure.
2. the structures such as abutment wall longitudinal direction construction joint, circular construction joint, inverted arch bottom and waterproof weak link recurring structure deformation,
Cracking and waterproof failure；Spraying water, gushing silt etc. occur in local location.
3. level of ground water seasonal fluctuations, causing lining cutting to bear " dynamic load " influences.In continuous rainfall or Severe rainstorm weather
Under the conditions of, level of ground water increases suddenly, and lining cutting bears higher hydraulic pressure.
The tunnel designed at present is largely to have inverted arch lining cutting.By taking one-tunnel two-tracks tunnel as an example, drainage system is with " tunnel
Draining in vivo " is Main Patterns, underground water discharge path are as follows: country rock → preliminary bracing → draining blind pipe → lateral sulcus → transverse drainage
Pipe → Central drain, the i.e. water on tunnel structure periphery are permeated by preliminary bracing enters tunnel structure sheet via draining blind pipe ejectment
Central drain within body, it is final to be discharged outside hole.
Drainage system in tunnel body main drawback is that:
1. thering is the pressure release point of pressure underground water to be respectively positioned on to be arranged inside lining cutting main structure, lining cutting main structure is caused to bear
Hydrostatic pressing or hydrodynamic range are larger.
2. Central drain (or lateral sulcus) is set within tunnel structure, the periphery underground water of main ejectment arch wall range, tunnel
Inverted arch ponding below can not effective ejectment, once under continuous rainfall or rainstorm weather, under Local topography inverted arch crevice water or
Pipeline water because can not in time ejectment cause hydraulic pressure sharply to increase.Under the effect of high hydraulic pressure, cause tunnel bottom inverted arch cracking failure.
3. tunnel is in underground water seasonal fluctuation zone etc. and the close region of extraneous hydraulic connection, in continuous rainfall or heavy rain
It under weather, because of groundwater run off abruptly increase, is limited by abutment wall sluicing pore size and spacing, it is difficult in time by its ejectment to tunnel structure body
In interior gutter, sharply increased so as to cause level of ground water.Under the effect of high hydraulic pressure, Lining cracks is caused to destroy.
4. being needed by ballast bed structure, hole auxiliary structures and tunnel cross-section engineering economy being restricted, consider that construction is difficult
The cross-section of river freedom degree of easy degree, hole medial sulcus or Central drain is little, and discharge capacity is limited, often causes water damage in hole.
5. excavating that control is more difficult, and it is big that tunnel bottom void slag cleans out difficulty completely, during operation since tunnel bottom is arc-shaped
Due to tunnel bottom underground water can not ejectment, Train induced load repeated action in addition easily causes tunnel bottom the disasters such as to rise soil.
Therefore, optimize liner structure and drainage system, guarantee that draining is unobstructed, reduce or even eliminate tunnel bottom water pressure, become drop
Low karst area tunnel water damage risk, guarantee operation security there is an urgent need to.
