Problems solved by technology
[0002] When the groundwater level is relatively high, the anti-floating anchor grouting is usually performed by grouting first and then inserting the rod body or the grouting pipe can also be bound on the anchor rod body, and enter the hole with the rod body for grouting, but when the groundwater is abundant Or due to site conditions, when there is a large water head difference at the anchor bolt, the mortar will often be discharged together with the groundwater, which will cause the above grouting method to fail, and the quality of the anchor bolt grouting cannot be guaranteed.

Abstract
The invention discloses an anti-floating anchor rod pressure grouting device, which comprises a thick steel pipe, wherein the lower part of the thick steel pipe is provided with a hole; the top of the thick steel pipe is sealed by a steel plate; the steel plate is provided with a grouting pipe and a slurry discharging pipe; the grouting pipe and the slurry discharging pipe are respectively provided with a valve. According to the anti-floating anchor rod pressure grouting device disclosed by the invention, the problem of anti-floating anchor rod grouting when underground water is abundant or the anchor rod position has a big water head difference because of the limitation of the site condition is solved, the construction quality and the construction progress are guaranteed, and the cost is reduced.
Description
technical field [0001] The invention relates to the field of anti-floating bolt construction, in particular to a pressure grouting device for anti-floating bolts. Background technique [0002] When the groundwater level is relatively high, grouting for anti-floating anchors is usually performed by grouting first and then inserting the rod body or the grouting pipe can also be bound on the anchor rod body, and enter the hole with the rod body for grouting, but when the groundwater is abundant Or due to site conditions, when there is a large water head difference at the anchor bolt, the mortar will often be discharged together with the groundwater, which will cause the above grouting method to fail, and the quality of the anchor bolt grouting cannot be guaranteed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an anti-floating bolt pressure grouting device. [0004] The present invention adopts following technica...
