Open caisson sinking assisting structure and using process thereof
The invention relates to the technical field of open caissons, in particular to an open caisson sinking assisting structure and a using process thereof. The open caisson sinking assisting structure comprises a steel blade foot and a water jetting device; the steel blade foot comprises a steel blade foot outer barrel, a steel blade foot pedal surface and a steel blade foot reinforcing ribs; the upper portion of the steel blade foot outer barrel is connected with an open caisson wall; the middle of the steel blade foot outer barrel is connected with the steel blade foot pedal surface; the lower portion of the steel blade foot outer barrel is connected with the steel blade foot reinforcing ribs; the top surface of the steel blade foot pedal surface is connected with the open caisson wall; the bottom surface of the steel blade foot pedal surface is connected with the steel blade foot reinforcing ribs; the bottom of each steel blade foot reinforcing rib has taper; the water jetting device comprises a plurality of high-pressure water conveying pipes and high-pressure water spray heads; the high-pressure water conveying pipes are connected with the high-pressure water spray heads; the high-pressure water conveying pipes are arranged along the inner wall of the well wall; the high-pressure water spray heads are arranged between the two steel blade foot reinforcing ribs; the steel blade foot works in the sinking process of the open caisson in two aspects; firstly, effective soil cutting is performed, and soil inside and outside the open caisson is separated in time; and secondly, when the soil body below the open caisson blade foot is hollowed out, the soil body outside the open caisson is not easy to enter the open caisson along the end face of the blade foot.
本发明涉及沉井技术领域，具体来说是一种沉井助沉结构及其使用工艺，所述钢刃脚包括钢刃脚外筒、钢刃脚踏面和钢刃脚加强肋，所述钢刃脚外筒上部连接沉井井壁，钢刃脚外筒中部连接钢刃脚踏面，钢刃脚外筒下部连接钢刃脚加强肋，所述钢刃脚踏面顶面连接沉井井壁，钢刃脚踏面底面连接钢刃脚加强肋，所述钢刃脚加强肋底部设有锥度；射水装置，所述的射水装置包括若干高压输水管和高压水喷头，高压输水管与高压水碰头连接，所述的高压输水管沿井壁内壁布置，高压水喷头设置于两个钢刃脚加强肋之间，钢刃脚在沉井下沉过程起二方面作业，一是可以有效切土，及时分离沉井内外土体；二是当沉井刃脚下土体掏空时，沉井外土体不易沿刃脚端面进入沉井内。
