Precise directional grouting device
The invention discloses a precise directional grouting device, and belongs to the technical field of underground grouting. The precise directional grouting device comprises a grouting machine and a grouting head, the grouting machine and the grouting head are connected through a pipeline, the grouting head is of a hollow structure and comprises an inner cavity, a sliding groove is formed in the bottom end of the outer wall of the grouting head, a grouting guide pipe is arranged in the sliding groove, and the grouting guide pipe is rotationally connected with the side wall of the sliding groove through a torsion rotating shaft; a guide plate is arranged in the inner cavity, a spring is arranged below the guide plate, a plurality of limiting blocks are arranged on the inner side of the bottom wall of the inner cavity, the inner cavity communicates with the sliding groove through a through hole, and a connecting piece is arranged between the torsion rotating shaft and the guide plate and used for controlling the torsion rotating shaft to rotate. The grouting pressure and the grouting effect are improved through the grouting guide pipe, grouting can be accurately carried out on a pretreatment part, the grouting head is prevented from being clamped due to instability of surrounding soil in the grouting process while hole descending difficulty of the grouting head is avoided, and the precise directional grouting device is simple in structure, novel in conception, convenient to use and high in practicability.
本发明公开了一种精准定向注浆装置，包括注浆机及注浆头，注浆机和注浆头之间通过管道连接，注浆头采用中空结构，包括内腔，注浆头外壁底端开设有滑槽，滑槽内设置有注浆导管，注浆导管与滑槽侧壁之间通过扭力转轴转动连接；内腔内设置有导向板，导向板下方设置有弹簧，内腔底壁内侧设置有若干限位块，内腔与滑槽之间通过通孔相连通，扭力转轴与导向板之间设置有连接件，用于控制扭力转轴转动，本发明适用于地下注浆技术领域，通过注浆导管增加注浆压力和注浆效果，能准确的达到预处理部位进行注浆，避免注浆头下孔困难同时防止注浆过程中因周边土体不稳定卡住注浆头，此结构简单，构思新颖，使用方便，实用性强。
