Problems solved by technology

Due to the complexity and concealment of underground seepage channels, it is often impossible to determine the location and depth of the pouring holes during construction, resulting in many disadvantages of these measures, such as high construction costs, difficult maintenance, etc., and the cement slurry particles are too large to penetrate into small pores, resulting in The anti-seepage effect is concentrated in a limited range around the perfusion hole

Embodiment Construction

[0008] Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various aspects of the present invention Modifications in equivalent forms all fall within the scope defined by the appended claims of this application.

[0009] Flocculants can be generally divided into two types according to their chemical composition: inorganic flocculants and organic flocculants. Flocculants are mainly groups with positive (negative) charges and some difficult-to-separate groups with negative (positive) charges in water. Particles or particles approach each other, reduce their potential, make them in an unstable state, and use their polymerization properties to concentrate these particles and separate t...

Abstract

The invention discloses an automatic flocculent precipitate tracking and seepage preventing technology for soil body seepage prevention and a usage method thereof. The technology adopts flocculating agents and a seepage prevention method, wherein the flocculating agents include an inorganic flocculating agent, an organic flocculating agent and the like. The automatic flocculent precipitate tracking and seepage preventing technology is wide in application range, simple, quick and convenient to construct, capable of saving a large amount of project investment and free of underground water layer damage.

Description

technical field [0001] The invention belongs to water conservancy construction technology, in particular to the seepage prevention technology of embankments. Background technique [0002] Soil seepage is a link that needs to be dealt with in river channels, embankments, reservoir dams and other projects, and plays a decisive role in ensuring the safety of the project. At present, the anti-seepage method in the project is mainly high-pressure injection of cement slurry. Due to the complexity and concealment of underground seepage channels, it is often impossible to determine the location and depth of the pouring holes during construction, resulting in many disadvantages of these measures, such as high construction costs, difficult maintenance, etc., and the cement slurry particles are too large to penetrate into small pores, resulting in The anti-seepage effect is concentrated in a limited range around the perfusion hole. Contents of the invention [0003] Purpose of the ...
