Double-slurry reinforcing device for shield construction
The invention discloses a shield construction double slurry reinforcing device which comprises a supporting platform, a lifting hydraulic rod fixedly connected with the supporting platform, a grouting box fixedly connected with the lower end of the lifting hydraulic rod, two partition plates fixedly connected with the middle of the grouting box, grouting drill pipes arranged at the bottom of the grouting box at intervals, and sliding holes formed in the partition plates. A round pipe with one closed end is slidably connected into the sliding hole, a supporting spring is fixedly connected between the upper end of the round pipe and the inner wall of the grouting box body, the grouting drill pipe is provided with a side hole, and the round pipe is provided with a grouting hole which can be located on the upper side or the lower side of the partition plate. The grouting drill pipes on the two sides communicate with the lower cavity all the time and are filled with the first grout in cooperation with the depth changes of the grouting drill pipes, the first grout is firstly filled into the grouting drill pipe in the middle, then the second grout is filled into the grouting drill pipe in the middle, and finally the first grout is filled into the grouting drill pipe in the middle, so that high-strength reinforcing grouting is conducted on the periphery of a soil body reinforced by the second grout low in strength; and therefore, the subsequent shield tunneling is more convenient.
本发明公开了一种盾构施工双浆液加固装置，包括支撑平台，支撑平台固定连接升降液压杆，升降液压杆下端固定连接灌浆盒体，所述灌浆盒体中部固定连接两个的隔板，所述灌浆盒体底部间隔设置灌浆钻管，所述隔板设置滑孔，所述滑孔内滑动连接一端封闭的圆管，圆管上端与灌浆盒体的内壁之间固定连接支撑弹簧，灌浆钻管设置侧孔，所述圆管设置灌入孔，灌入孔能够位于隔板上侧或下侧。本发明通过配合灌浆钻管深度变化，两边的灌浆钻管始终与下腔室连通并灌入第一浆液，中部的灌浆钻管先灌入第一浆液，随后灌入第二浆液，最终灌入第一浆液，从而使得在强度不高的第二浆液加固土体外围进行高强度的加固注浆，从而使得后续盾构掘进更加便利。
