一种加固粉细砂的钢花管注浆结构
摘要：
本实用新型公开了一种加固粉细砂的钢花管注浆结构，包括钢管、四棱锥脚、护罩和把杆，钢管正面、背面以及左右两侧分别开设有注料孔，注料孔的外部设有护罩，护罩和钢管固定连接，护罩一侧设有护罩开口；所述钢管下端和四棱锥脚的顶部固定连接，钢管上端设有按压机构，钢管上端正面、背面以及左右两侧分别固定连有把杆。本实用新型的优点：通过设置半球状的护罩，增强护罩抗压能力，并且同方向设置若干护罩开口，配合把杆转动钢管，由护罩侧面的护罩开口出浆，极大的降低了其出浆压力，进而提高了注浆效果，有效的解决了注浆孔在粉细砂压力下会堵塞的问题。
摘要（英）：

The steel floral tube grouting structure for reinforcing silty-fine sand comprises a steel tube, rectangular pyramid feet, a protective cover and a handle rod, material injection holes are formed in the front face, the back face, the left side and the right side of the steel tube respectively, the protective cover is arranged outside the material injection holes, the protective cover is fixedly connected with the steel tube, and a protective cover opening is formed in one side of the protective cover. The lower end of the steel pipe is fixedly connected with the top of the rectangular pyramidfoot, and the upper end of the steel pipe is provided with a pressing mechanism. The device has the advantages that the device is simple in structure; by arranging the hemispherical protective cover,the pressure resistance of the protective cover is enhanced, the protective cover openings are formed in the same direction, the steel pipe is rotated in cooperation with the handle rod, slurry is discharged from the protective cover openings in the side face of the protective cover, the slurry discharging pressure of the protective cover is greatly reduced, the grouting effect is improved, and the problem that a grouting hole is blocked under the pressure of silty-fine sand is effectively solved.
