Problems solved by technology

Another disadvantage of using straw or cotton rope as a slurry stopper is that the cotton rope or straw rope is for one-time use, and the used straw or cotton rope cannot be directly buried (it needs special treatment before it can be landfilled), and cannot be used It is not friendly to the environment, especially cotton rope

Embodiment 1

[0037] In this example, a pipe pile joint seam stop slurry is prepared, and the specific process is as follows: 63% fly ash, 1% pregelatinized starch, 0.1% methyl hydroxypropyl cellulose ether by mass percentage (viscosity (20℃) is 100000mPa·s), 1% bentonite, 0.1% polypropylene fiber (about 9mm in length), 2.5% crushed rubber particles (mesh 40-70 mesh) and balance water Stir and mix well to prepare pipe pile joint seam stop slurry.

Embodiment 2

[0039] In this example, a pipe pile joint seam-stopping slurry is prepared. The specific process is as follows: 70% by mass of fly ash, 2% of pregelatinized starch, and 0.5% of methyl hydroxypropyl cellulose ether (viscosity (20℃) is 100000mPa·s), 2% bentonite, 0.5% polypropylene fiber (about 12mm in length), 5% crushed rubber pellets (mesh 40-70 mesh) and balance water Stir and mix well to prepare pipe pile joint seam stop slurry.

Abstract

The invention discloses a grout-stopping slurry for joint joints of pipe piles and a preparation method and application thereof, belonging to the technical field of pipe piles. The pipe pile joint seam-stopping slurry of the present invention has a little elasticity, can only fill the gap after being clamped by the mold, and will not cause the gap to be lifted up, causing the mold to deform, and has good deformation resistance; The viscosity of the slurry makes it difficult for the slurry to be thrown out of the gap during centrifugation, and achieves a good slurry stop effect. At the same time, it will not cause excessive viscosity to the mold. After the slurry is evaporated to dryness, it can form a block, so that the slurry can be released smoothly when it is demolded and cleaned, so as to overcome the dust generated when the powder slurry is removed, which affects the working environment.

Description

technical field [0001] The invention belongs to the technical field of pipe piles, and in particular relates to a pipe pile joint joint grout-stopping slurry and a preparation method and application thereof. Background technique [0002] At present, in the production of pipe piles, the defective products caused by the leakage of slurry at the joints account for more than 50% or even more of the defective products of the whole pipe piles, which is the most troublesome problem in the pipe pile industry. Although many ways have been thought of, it has always been difficult to control effectively. After research, in the production process of pipe piles, the deformation of the mold is the most difficult to avoid effectively through the process operation method. Once the mold is deformed, it is easy to produce different degrees of slurry leakage. In order to reduce slurry leakage, workers can only use more straw or cotton ropes to block the gaps. As everyone knows, this move fur...
