Soil nail grouting head device and construction method thereof
The invention relates to the technical field of soil nail grouting heads, and discloses a soil nail grouting head device which comprises a hard pipe, a hose, a soil nail hole and a soil nail reinforcing steel bar, the top end of the hard pipe is fixedly connected with the hose, the surface of the hard pipe is sleeved with a metal pipe, and the center of the surface of the metal pipe is fixedly sleeved with a limiting ring; and a movable ring is movably arranged on the surface of the metal pipe and located below the limiting ring in a sleeving mode, and an annular groove is formed in the surface of the movable ring. Through cooperation of structures such as the metal pipe, the movable ring, the top block, a movable plate and a triangular block, when the grouting head is plugged into a soil nail hole for grouting, slurry extrudes the movable ring to enable the movable ring to move upwards, and at the moment, the movable ring can open the top block through the movable plate and the triangular block; and the end part of the top block can extrude the inner wall of the soil nail hole so as to increase the upward moving resistance of the grouting head, so that slurry can permeate into the soil nail hole during grouting so as to increase the strength of the soil nail.
本发明涉及土钉注浆头技术领域，且公开了一种土钉注浆头装置，包括硬质管、软管、土钉孔和土钉钢筋，所述硬质管顶端与软管固定连接，所述硬质管的表面套设有金属管，所述金属管的表面中心处固定套设有限位环，所述金属管的表面且位于限位环的下方活动套设有活动环，所述活动环的表面开设有环槽。本发明通过设置金属管、活动环、顶块、活动板和三角块等结构的配合，从而在将该注浆头塞入土钉孔内部并进行注浆时，泥浆会挤压活动环使其向上移动，此时活动环就会通过活动板和三角块来将顶块撑开，顶块的端部就可以挤压土钉孔内壁，以增加注浆头向上移动的阻力，这样注浆时泥浆就可以向土钉孔内部渗透以增加该土钉的强度。
