Description
Technical field
The present invention relates to the Antiseep method of a kind of underground building structure, particularly the method that the disease of tunnel percolating water is punished belongs to the building structure construction technical field.
Background technology
Tunnel percolating water is one of common disease in domestic and international tunnel, and tunnel percolating water shows as mainly that the arch leaks, abutment wall drops down water, constuction joint, deformation joint and distress in concrete percolating water, rises soil at the bottom of the tunnel etc.
The tradition of highway tunnel percolating water is administered, and is to determine resolution and select material according to the water source, type, position and the water leakage that leak.Generally reperfusion serosity polyurethane or the filling of ordinary Portland cement list liquid slurry are adopted in arch and abutment wall lining cutting cavity behind, lining cutting surface EXIT POINT adopts the slip casting shutoff, constuction joint percolating water is adopted ejectment or slip casting shutoff, the method that the wet stain on lining cutting surface adopts slip casting and smears water-repellent paint is carried out shutoff, to methods such as concrete weak part employing grouting reinforcings.Follow during punishment and go up afterwards earlier, arch back wall adopts cement grout shutoff big flood earlier, the principle that adopts chemical grout shutoff percolating water again and drip earlier.The common high pressure chemistry slip casting method for repairing and mending that adopts, be temporary transient or provisional leak stopping, recurrence frequency height, the anti-seepage effect instability can not forever solve leakage problem, simultaneously up hill and dale, because repeatedly slip-casting is repaired (structurally punching too much), cause the intensity of concrete structure to reduce, have side effects, thereby influence application life of structure.
1807, German Reuss professor found the sign of liquid flow in containing the pore structure at first in Russia's experiment.Nineteen thirty, Switzerland Ernst brother finds in containing the structure of pore, after applying electric charge between the both positive and negative polarity, and the principle that the water in the structure can be removed.According to these discoveries, produced multiple-pulse electricity antiseepage (MPS) technology subsequently.
Electricity antiseepage (MPS) system is a multiple-pulse electro osmosis waterproof technique most advanced and perfect in the world today, its principle is that the control device of MPS system produces a series of action of low-voltage pulse electric charge, electromagnetic field by the positive and negative electrode formation, affact on the hydrone in interior pore of structure and the slit, its ionization; The hydrone that is ionized moves towards the negative electrode direction that is installed in the structure outside, thereby the moisture of inside configuration is drained and exsiccation gradually.This technology has been used decades, mainly be used in waterproof, antiseepage, leak stopping and the dehumidify field of (as concrete, masonry structure) in the structure of underground building, and obtained success, demonstrated the remarkable ability of its impervious leakage-stopping, the anti-seepage effect of this technology has obtained sufficient proof in the famous engineering in Norway, Britain and Hong Kong.But this technology only is only applicable to the seepage prevention of pore in the structure, and for the serious seepage that the tunnel that has built up causes owing to complicated factor, regulation effect is unsatisfactory.
Because Yunnan geological structure complexity, more than any single seepage control technique all can not obtain effect preferably, and multiple-pulse electro osmosis waterproof technique application example in the tunnel antiseepage is less, therefore need grope rational job practices, just can reach best anti-seepage effect.
Summary of the invention
Technical problem to be solved by this invention provides a kind of tunnel and comprehensively punishes the seepage method, and long-term comprehensive cost of this method and running cost are low, and installing engineering is flexible, decline to a great extent in the splash guard function, have a large amount of cracks, under the infiltration serious situation, the waterproof, seepage control effect is obvious.
Solving the scheme that technical problem of the present invention adopts is: at first build at tunnel double-lining and carry out chemical liquids slip casting shutoff around leaking, produce the joint seal colloid at the place, crack of building structure; Build the surface at tunnel double-lining then and leave snakelike reciprocal groove, titanium metal wire is installed as anode line in the groove, link to each other position installation copper rod as cathode line at the tunnel double-lining back side with the soil body, the cloudy the two poles of the earth of sun line is aggregated into electric antiseepage control cabinet and is connected with central control cabinet, energising produces the action of low-voltage pulse electric charge, and the water that is ionized is moved towards the cathode direction outside the tunnel.
Concrete technical scheme of the present invention is: the water of polyurethane and pH6～7 is mixed into chemical grout, fills with the high-pressure slip-casting machine crack of will seeping water under the pressure of 20MP～30MP, and grouting at the end should continue pressure more than 20 minutes; Tunnel double-lining is built on the surperficial concrete and to be dug dark 2cm～2cm, and the stria of wide 0.5cm～1cm cleans up with clear water after ending groove; Install the slit of the groove of titanium metal wire with graphite and cement mixing slurry shutoff titanium metal wire and groove; It is that 1m at the bottom of the distance tunnel～2m place boring penetrates abutment wall and stretches into the soil body that the negative electrode copper rod is installed, and copper rod is tied with electrical insulating film at the position of tunnel double-lining.
When carrying out chemical liquids slip casting of the present invention, injected hole should be to tilt 30 °～45 ° with tunnel infiltration face, the both sides that are chosen in the crack of the perfusion point of injected hole, and the crack should be passed in the hole.
The present invention at first carries out the change filling of routine techniques, chemical grout polyurethane with can be during very short time (10 seconds) after water mixes rapid expansion, the generation colloid, colloid plays the joint sealing effect along crack movement.Electro osmosis antiseepage line system is installed in the tunnel is then carried out the tunnel antiseepage, after connecting the power supply transformation, central authorities' control cabinet is sent to electric antiseepage (MPS) control cabinet with 36 volts of low currents, electric current produces electron ion with the moisture content ionization in the concrete, electron ion flows to the negative electrode direction under the continuous promotion of electric current be the structure outside, do not flow backwards, make structure become dry state.The energy that the hydrone that is ionized moves can bear the water under high pressure effect greater than the energy of the siphonage power of pore in gravity and structure of water.As long as apply the positive negative pulse stuffing electric charge continuously, the water in the structure will move towards negative electrode one side (the structure outside) always, can form seal antiseepage barrier one, and punishment water or moisture infiltrate in the structure.The underground structure that has free flow water to ooze out is changed the interim sealing of filling earlier, carry out the installation of electric seepage control system again.Normal dry run needs 1-3 month, and in particular cases maximum 3 months, (seawater is faster than fresh water rate of drying).Method of the present invention can be punished for a long time and be produced new crack generation, and its punishment time of penetration can be for 50 years.
The invention has the beneficial effects as follows: by chemical liquids slip casting method and the combination of multiple-pulse electro osmosis waterproof technique, the long-term comprehensive cost and the running cost of tunnel antiseepage are reduced greatly, installing engineering is flexible; Decline to a great extent in the splash guard function, have a large amount of cracks, under the infiltration serious situation, the waterproof, seepage control effect is obvious.
