Material filling device for plugging high-pressure underground water

Abstract

The invention belongs to the technical field of waterproof engineering construction and particularly relates to a material filling device for plugging high-pressure underground water, which can realize deeply plugging high-pressure underground water in a deep excavation well, an exploration well and the like. The device mainly comprises an exhaust pipe, a material injecting steel pipe, a materialcontaining bag, fixing buckles, discharge ports, filter sponge, a pressure gauge, a pump truck, a flow meter and a material injecting inner pipe. Specific application procedures are as follows: the water pressure and the well depth are measured; the material injecting steel pipe and the discharge ports are prepared; the material containing bag and the fixing buckles are bound; the material injecting inner pipe is then placed in the injecting steel pipe to spout concrete to the material containing bag until the material containing bag is closely attached to the well wall. The main structure issimple, the design is ingenious, the use is convenient and safe, smooth plugging of the high-pressure underground water can be realized, the application environment is environmentally friendly, and the market has broad prospects.

Description

Technical field: [0001] The invention belongs to the technical field of waterproof engineering construction, and in particular relates to a filling device for sealing high-pressure groundwater, which can realize deep sealing of high-pressure groundwater including deep-dug wells and exploration wells. Background technique: [0002] At present, when constructing underground tunnels, underground chambers, subways or other underground construction works, it is usually necessary to carry out geological exploration first. During site exploration, exploration wells with a depth of 60 meters are usually drilled. The wells have extremely high-pressure groundwater at a relatively deep level, which has a great impact on subsequent underground construction. At the same time, in some places where deep-dug wells are close to the depth of exploration wells, how to deal with high-pressure groundwater in deep-dug wells to avoid Affecting the construction of the lot is also a problem. The ex...

Problems solved by technology

In order to solve the above problems, one method in the prior art is to grout the high-pressure groundwater, usually using chemical grouting, cement grouting, cement-sodium silicate double-liquid grouting, chemical grouting will pollute the environment, the grouting effect is not obvious, and the cost However, the current method of double-fluid grouting is to fill the boreholes independently, which is not only difficult to control the solidification time of the grout, especially in the high-pressure groundwater grouting treatment, the double-fluid grout that is too late to solidify is easily destroyed by high pressure. The water jet dilutes and washes away, and the expected grouting purpose cannot be achieved

One is to quickly inject quick-drying cement into the depths of the well under high pressure. However, due to the excessive water pressure and water volume, the quick-drying components in the cement are rapidly diluted, so that the cement can only condense into smaller particles and float on the water, and cannot Condensed into a complete concrete structure
