Abstract
The invention provides mould bag slip casting (material) dynamic water plugging method and apparatus in a kind of macrovoid, be economical, solve the new technology of moving water seal leak stopping in the macrovoid easily.It is the boring of adopting smaller aperture due, slip casting (material) pipe by the setting in holing injects certain material is delivered to macrovoid in advance by slip casting (material) pipe to slip casting (material) pipe bottom mould bag, the mould bag is expanded, occupy the certain space in the macrovoid and then play the effect of water blockoff.
Description
The present invention relates to the moving leakage stopping technology that seals of underground construction macrovoid under water.Be adapted to the sealing leak stopping of the moving water of high flow rate in the macrovoid.
Existing underground hole dynamic water plugging adopts large diameter pilot tunnel backfill sandstone material etc. or concrete, or reduces the grout sealing that the laggard scanning frequency of hole is coagulated slurries.The said method quantities is big, the cost height, and be difficult to solve the sealing leak stopping problem of the moving water of high flow rate in the macrovoid.
Task of the present invention provides a kind of method and apparatus, can solve economical, easily the moving sealing leakage stopping technology under water of macrovoid.
Invention is finished like this: adopt the boring of smaller aperture due, be drilled into the sealing leak stopping place of the moving water of macrovoid.As required with local material situation and aperture, adopt the plugging material such as cement, sand material, earth material or concrete or be made into flowable slurries, slip casting (material) pipe by the setting in holing injects the mould bag that slip casting (material) pipe bottom arranges, and this mould bag is delivered in the macrovoid by slip casting (material) pipe in advance.The mould bag can adopt woven bag or other type bag of the various materials with sufficient intensity, especially adopts the mould bag of permeable not saturating solid particle for well, is conducive to slurries discharging consolidation and set strength.The size of mould bag and shape can be determined with condition as required, send into sealing leak stopping place by boring, sack links to each other with slip casting (material) pipe, connection can be adopted the backpitch screw thread, one end colligation mould sack, one end links to each other with slip casting (material) pipe, also can adopt the alternate manner that both can be separated in slip casting (material) back, as flexible pipe.When slurries (or material) injection mould bag, progressively the mould bag expands, and occupies the certain space in the macrovoid.Since mould bag and slip casting (material) pipe link to each other with the mould bag to the deadweight of the protective effect of slurries (or material), slurries (or material) and fixed with solidify after intensity etc.; make it have the effect of the underground moving water of opposing and be not flushed away, and then play the effect of water blockoff.What mould bag and slurries (or material) had adjusts the ability of self shape with hole, helps the dead-end pore.When hole very huge, can not the complete closed hole after the single mould bag slip casting (material), then can adopt this boring or a plurality of boring, a plurality of mould bag slip casting (material) repeats leak stopping, until the sealing leak stopping is till satisfied.
Use this method can solve the moving sealing leak stopping difficult problem under water of underground macrovoid high flow rate, it has the characteristics such as technology is simple, the sealing water plugging effect is good, and is cheap, can bring obvious economic and social benefits to engineering.
Claims (3)
1, adopts the boring of smaller aperture due, slip casting (material) pipe by the setting in holing injects certain material is delivered to macrovoid in advance by slip casting (material) pipe to slip casting (material) pipe bottom mould bag, the mould bag is expanded, occupy the certain space in the macrovoid and then play the effect of water blockoff.It is characterized in that:
The boring of a, employing smaller aperture due is drilled into the sealing leak stopping place that macrovoid moves water.
B, adopt plugging material such as cement, sandstone material, earth material or concrete or be made into flowable slurries.
C, mould bag can adopt woven bag or other type bag of the various materials with sufficient intensity.
