Description
Technical field
The present invention relates to field, tunnel, be specifically related to a kind of waterproof for tunnel in cold area, insulation and the system of pressure regulation and
Apply method.
Background technology
China's district's area distributions of trembling with fear is extensive, and trip demand is vigorous, and Tunnel Engineering is as the effective means crossed over mountain after mountain
It is widely adopted.In the winter time, freezing damage in tunnel happens occasionally, on the one hand show as ice slip, icicle, the ice formation issues such as ice berg, another
Aspect shows as tunnel structure and is caused breakage by frost-heave force problem, fall block and even cave in problem.Tunnel in cold area is caused to occur freezing
Evil problem, the groundwater treatment and the Insulation that are primarily due to tunnel are not in place.If effectively solving subsoil water and tunnel being protected
Temperature problem, becomes the key of tunnel in cold area freezing prevention.
For the process of subsoil water, tunnel in cold area in addition to emphasizing concrete self-waterproof, commonly used splash guard+hoop
Blind pipe, longitudinal french drain and the guarded drainage countermeasure of insulation gutter (buried Central drain).Although this measure has highlighted that water-proof sheet material
Tensile property, but due to preliminary bracing surface irregularity, make splash guard be difficult to the most closely connected with preliminary bracing surface, cause filling
There is the problem such as local elongation and behind leakiness during note secondary lining concrete, add inevitable joint treatment and ask
Topic, causes the water resistance of splash guard to be greatly lowered.In order to solve this problem of groundwater treatment, need to improve the paving of splash guard
If technology and technique.For the insulation problem of tunnel in cold area, at present universal the most in the early stage between supporting and secondary lining or secondary lining
The inner surface built is laid warming plate and is reached the purpose of insulation.By construction technology, insulation material compressive property and thickness etc. because of
The impact of element, heat insulation effect is restricted.For the problem in terms of current tunnel in cold area guarded drainage and insulation, integrating tunnel is tied
The mechanical property of structure, need to try every possible means from tunnel artificial structure, to obtain essence breakthrough.

The rubber pneumatic bag unit of gas；
Step 2: inflate to rubber pneumatic bag unit, and adjust rubber pneumatic bag cell configuration and adapt it in preliminary bracing
Size, it is ensured that the pressure match of each rubber pneumatic bag unit；
Step 3: with the rubber pneumatic bag unit after inflation as external mold, is interior mould with two lining chassis, carries out secondary lining coagulation
The perfusion of soil, completes Tunnel Second Lining；
Step 4: by monitoring the pressure of rubber pneumatic bag unit, in conjunction with the bearing capacity of secondary lining, it is achieved rubber pneumatic bag
The pressure regulation of unit.
The invention have the benefit that and pressure regulating course is set between supporting and secondary lining in the early stage, can effectively pass
Pass pressure from surrounding rock, the frost-heave force that winter is increased or other unexpected power, by self-deformation and pressure regulation, it can be entered
Row is offset, it is to avoid secondary lining damages.
This pressure regulating course is slapped together by rubber pneumatic bag unit, and be filled with in rubber pneumatic bag unit have compressibility and
The gas of high thermal resistance, and rubber pneumatic bag unit and the immobilising air being filled with are all hot non-conductors, this rubber bag tank can
The effective transmission stoping heat, forms thermal insulation layer in the early stage between supporting and secondary lining.
Using lenticular sealing structure between rubber pneumatic bag unit, this lenticular sealing structure has the spy of water-swellable
Levy, then be aided with the blowing pressure regulation, it is ensured that the closing contact between each rubber pneumatic bag unit, it is possible to waterproof, when having water from the initial stage
Supporting penetrates, above the water swelling of lenticular sealing structure, it is possible to when ensureing there are current, the very first time blocks current and oozes
Thoroughly.
The self-closing valve switch being provided with at this rubber pneumatic bag unit and pressure transducer, can pass through pressure transducer pair
Actual pressure suffered by rubber pneumatic bag unit carries out accurate measurements.By the self-closing valve switch of rubber pneumatic bag unit, can
To complete pressure regulation work, when monitoring pressure and being low, rubber pneumatic bag unit is inflated supercharging；And during hypertonia, enter
The a certain degree of venting of row allows pressure.Rubber pneumatic bag unit after inflation is possible not only to carry out the most levelling to preliminary bracing, and
The external mold of concrete can be molded into, to ensure to be molded into the quality of coagulation as secondary lining.
