Disc type internal circulation depressurization grouting device and method
The invention provides a disc type internal circulation depressurization grouting device, and relates to the technical field of pipeline drilling construction. The grouting mechanism comprises a plurality of disc plates, a connecting rod, an external exposed pipe and a plurality of lifting hooks, the disc plates are arranged at intervals in the vertical direction and connected through the connecting rod, built-in concealed pipes are arranged in the disc plates, the disc plates are further provided with water outlet holes formed in a penetrating mode, at least one end of each built-in concealed pipe extends to the side wall of the corresponding disc plate, and the other end of each built-in concealed pipe extends to the side wall of the corresponding disc plate; the external exposed pipe penetrates through the disc plates and is sequentially connected with the internal concealed pipes of the disc plates from bottom to top, the uppermost disc plate is hung at the upper port of the tube well through the lifting hooks, and the grouting pipe is connected with the external exposed pipe; and a counterweight. The device has the beneficial effects that slurry is injected between the disc plates layer by layer from bottom to top, the pressure of the slurry below the tube well is large, underground water with the large pressure below the tube well can be just squeezed upwards, the water flow pressure is gradually reduced in the process that the underground water moves upwards through the water outlet holes, and the blocking difficulty is reduced.
本发明提供一种碟片式内循环降压注浆装置，涉及管道钻进施工技术领域，包括：盖帽机构；注浆机构，其包括多个碟片板、连接杆、外置明管和多个吊钩，各碟片板沿着竖直方向间隔设置且通过连接杆连接，碟片板的内部设有内置暗管，碟片板还设有贯穿设置的出水孔，内置暗管的至少一端延伸至碟片板的侧壁，外置明管穿过各碟片板且由下至上依次连接各碟片板的内置暗管，位于最上方的碟片板通过各吊钩吊挂于管井上端口，注浆管连接外置明管；以及配重件。本发明的有益效果：浆液由下至上逐层注入各碟片板之间，浆液在管井下方压力较大恰好可以将管井下方压力较大的地下水向上挤压，地下水在通过出水孔向上运动过程中水流压力也逐步减小，封堵难度降低。
