Large-depth full-section type high polymer anti-seepage curtain grouting device and method
The invention belongs to the technical field of water conservancy facility anti-seepage repairing, and relates to a large-depth full-section type high polymer anti-seepage curtain grouting device and method. The grouting device comprises two grouting pipes and a mixing chamber connected with the lower ends of the grouting pipes through first one-way valves, each grouting pipe is of a sectional structure connected through a quick connector, a hole packer is arranged outside the mixing chamber, a net-shaped partition plate is arranged inside the mixing chamber, the lower portion of the mixing chamber is connected with a grout outlet pipe through a quick connector, a plurality of grout outlet holes are formed in the circumferential face of the grout outlet pipe, and a plurality of blades are arranged on the outer side face of the grout outlet pipe. According to the grouting device, the grouting pipes are of a sectional structure connected through the quick connectors, lifting and dismounting operation is easy, sectional grouting operation is convenient, and therefore full-section grouting plugging of the whole grouting hole is achieved.
本发明属于水利设施防渗修复技术领域，涉及一种大深度全段式高聚物防渗帷幕注浆装置及方法，该注浆装置包括两根注浆管和与注浆管下端通过第一单向阀连接的混合室，每根所述注浆管均为通过快速接头连接的分段式结构；所述混合室外部设置封孔器，所述混合室内部设置有网状隔板，混合室下部通过快速接头连接出浆管，所述出浆管圆周面上开设多个出浆孔，所述出浆管外侧面设置多个叶片。本发明注浆装置注浆管采用通过快速接头连接的分段式结构，提升拆卸操作简单，方便进行分段注浆操作，以实现整个注浆孔的全段式注浆封堵。
