Water pressure type expansion hole sealing pipe for high-pressure grouting of root pile
The invention relates to the technical field of high-pressure grouting, and discloses a root pile high-pressure grouting hydraulic pressure type expansion hole sealing pipe which comprises a steel pipe, a grouting pipe and an expansion pipe. A water injection opening is formed in the expansion pipe and connected with the hydraulic pump through a water injection pipe, and the water injection pipe communicates with a drainage pipe; when the drainage valve is closed, water is injected into the deformation space, the peripheral annular wall expands outwards and deforms until the peripheral annular wall fixedly abuts against the inner side wall of the steel pipe, and the steel pipe is closed; when the water pressure pump is closed, the water is discharged through the drainage pipe, the peripheral ring wall shrinks and recovers deformation, the peripheral ring wall breaks away from abutting against the inner side wall of the steel pipe, and the steel pipe is opened; the hole packer can resist high-pressure acting force of grout to be fixed in the steel pipe, after grouting is completed, the drainage valve drains water in the deformation space through the drainage pipe, the peripheral annular wall elastically retracts and breaks away from abutting on the inner side wall of the steel pipe, the hole packer is convenient to install and construct, and the high-pressure grouting hole sealing effect is good.
本发明涉及高压注浆的技术领域，公开了树根桩高压注浆水压式膨胀封孔管，包括钢管、注浆管以及膨胀管，膨胀管具有外周环壁；膨胀管上设有注水口，注水口通过注水管与水压泵连接，注水管连通有排水管；当关闭排水阀，水体注入变形空间内，外周环壁朝外膨胀变形，直至外周环壁固定抵压在钢管的内侧壁上，将钢管封闭；当关闭水压泵，水体通过排水管排出，外周环壁收缩恢复变形，外周环壁脱离对钢管的内侧壁的抵压，钢管打开；封孔器可以抵抗浆液高压发作用力固定在钢管内，注浆完毕，排水阀将变形空间内的水体通过排水管排出，外周环壁弹性回缩，脱离对钢管的内侧壁的抵压，封孔器安装施工方便，高压注浆封孔效果好。
