Freezing construction method for high-permeability confined water sand layer of metro connecting channel
The invention relates to the technical field of freezing methods, and discloses a subway connection channel high-permeability confined water sand layer freezing construction method which comprises an outer pipe and an inner pipe and further comprises a stirring device, an auxiliary freezing device and a discharging device. The stirring device comprises an outer spiral blade, a shaft sleeve, a stirring plate, a water outlet hole and a water pump, the shaft sleeve is rotationally connected to the surface of the inner pipe, the outer spiral blade is fixedly connected to the surface of the shaft sleeve, the stirring plate is fixedly connected to the surface of the outer spiral blade, the water outlet hole is formed in the surface of the inner pipe, and the water pump is installed on the inner wall of the inner pipe. Through cooperative operation of the outer pipe, the inner pipe, the water outlet hole, the shaft sleeve, the outer spiral blade, the stirring plate and the water pump, the temperature of saline water at all positions is the same, it is ensured that a high-permeability sand layer on the outer surface of the outer pipe can be evenly cooled, and it is prevented that high-permeability sand layers with different freezing effects affect subsequent engineering.
本发明涉及冻结法技术领域，且公开了地铁联络通道高渗透性承压水砂层冻结施工方法，包括外管和内管，还包括搅拌装置、辅助冷冻装置和排料装置；所述搅拌装置包括有外螺旋叶片、轴套、搅拌板、出水孔和水泵，所述轴套转动连接在内管的表面，所述外螺旋叶片固定连接在轴套的表面，所述搅拌板固定连接在外螺旋叶片的表面，所述出水孔开设在内管的表面，所述水泵安装在内管的内壁，本发明通过外管、内管、出水孔、轴套、外螺旋叶片、搅拌板、水泵之间的配合运作，从而使得各处盐水的温度相同，确保外管外表面的高渗透性砂层会进行均匀的降温，防止出现冻结效果不同的高渗透性砂层，进而影响后续的工程。
