Water stop needle head capable of quickly grouting
The invention belongs to the technical field of grouting water-stopping needles, and provides a water-stopping needle capable of quickly grouting, which comprises a grouting pipe, a slurry input device comprises a grouting head and an acceleration grouting device with a circulation cavity, the grouting head is detachably connected to a top opening of the grouting pipe, and the acceleration grouting device is connected with the circulation cavity. The grouting head comprises an inverted slurry head and a slurry head connecting part extending downwards from the bottom plane of the inverted slurry head, the inverted slurry head is provided with a first longitudinal flow channel, the slurry head connecting part is detachably connected to the top opening of the grouting pipe, and the slurry head connecting part is provided with a second longitudinal flow channel communicated with the first longitudinal flow channel; the radial diameter of the first longitudinal flow channel is smaller than that of the second longitudinal flow channel; and the upper part of the side wall of the accelerating grouting device is embedded into the second longitudinal runner, and the lower part of the accelerating grouting device is screwed on the inner cavity wall of the grouting pipe. Compared with the prior art, the accelerating grouting device is arranged, the flow collecting effect is achieved, the rapid grouting effect can be achieved, and the technical advantages of being high in grouting efficiency, high in speed and short in consumed time are achieved; and the slurry backflow prevention effect is achieved.
本发明属于注浆止水针头技术领域，现提供一种可以快速注浆的止水针头，它包括注浆管，浆液输入装置包括注浆头和具有流通腔的加速注浆器，注浆头可拆卸地连接于注浆管顶开口，注浆头包括倒筒浆头、由倒筒浆头底平面朝向下延伸的浆头连接部，倒筒浆头开设有第一纵向流道，浆头连接部可拆卸地连接至注浆管顶开口，浆头连接部开设有与第一纵向流道连通的第二纵向流道，第一纵向流道的径向直径小于第二纵向流道的径向直径；加速注浆器侧壁的上部分嵌入第二纵向流道内，其的下部分螺固于注浆管内腔壁上。与现有技术相比，设置加速注浆器，形成集流作用，可以实现快速注浆效果，具有注浆效率高、速度快、用时短的技术优点；且具有防浆液回流效果。
