Title:
GROUTING APPARATUS FOR HIGHLY COAGULATIVE GROUTING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2022/007694
Kind Code:
A1
Abstract:
The present invention relates to the field of grouting, and in particular to a grouting apparatus for a highly coagulative grouting material. The grouting apparatus comprises a grouting pipe, a connector and a self-sealing pipe head. One end of the connector is connected to a grouting pump through the grouting pipe. The other end of the connector is connected to the self-sealing pipe head through the grouting pipe. The grouting pipe has fixed, sealed connections with the connector and the self-sealing pipe head. The grouting apparatus is easy to install. The grouting pipe is reliably connected to the connector and the self-sealing pipe head, and is reusable. The inner diameter of the connector matches the inner diameter of the grouting pipe, and the slurry outlet on an end cap of the self-sealing pipe head is circular, thereby effectively reducing pressure loss during a grouting process and having good grouting effects.
