Abstract

The invention discloses a preparation process of a self-caulking anti-seepage curtain-type prefabricated concrete pile, belonging to the technical field of concrete prefabricated piles. The invention can realize the method of pre-embedding a curtain-type steel cage, which not only improves the strength of the prefabricated pile body, but also improves the strength of the prefabricated pile body. The specially set water diversion and caulking rods are used to form a tight mesh structure through targeted diffusion and distribution. The anti-seepage detection is carried out on the outer surface of the prefabricated pile body. When the existence of cracks and water seepage are detected, the water diversion and caulking rods will penetrate The water is brought in to trigger the caulking procedure, using the characteristics of the gas push ball to react with water to release gas, to promote it to migrate to the crack, and then use the gas to force the self-releasing plugging rod to disintegrate to release the raw material used for caulking. When it comes into contact with permeated water, it reacts with the raw material close to the precast pile body and the adhesive to seal the cracks, and the reaction releases a lot of heat, which is conducive to evaporating the permeated water in the nearby area, and significantly improves the impermeability of the concrete precast pile. .

Description

technical field

[0001] The invention relates to the technical field of concrete prefabricated piles, in particular to a preparation process of a self-caulking anti-seepage curtain type concrete prefabricated pile. Background technique

[0002] Concrete piles are piles made of concrete (including ordinary reinforced concrete and prestressed concrete). and other ground treatment. As the prefabricated piles to hide the foundation, prefabricated concrete piles with a side length of 150-300mm, prestressed concrete pipe piles with a diameter of 300mm, steel pipe piles with a cross-sectional size of 100-300mm, and profiled steel can be used.

[0003] Concrete is a porous body with different pore sizes (10-500μm). When there is a pressure difference in the surrounding medium (or concentration difference, temperature difference, potential difference), there will be media migration that obeys fluid mechanics, that is, infiltration. The impermeability of concrete is the basic perform...
