Pile sinking device for assisting prefabricated hollow pile in frozen soil area
The invention discloses a pile sinking device for assisting a precast hollow pile in a permafrost region, which comprises a pile body, an auxiliary cylinder is movably mounted in the pile body, an electric heating block capable of penetrating through the bottom of the pile body is fixedly connected to the bottom of the auxiliary cylinder through a connecting rod, the pile sinking device further comprises a medium pipe extending out of the auxiliary cylinder from the inside of the auxiliary cylinder, and the two ends of the medium pipe extend out of the pile body. And a fixing device is also arranged on the auxiliary cylinder. The auxiliary cylinder and the electric heating block are mounted in the pile body, so that the electric heating block extends to the bottom of the pile body, and during pile sinking operation, the electric heating block is electrified and generates heat to melt frozen soil at the bottom of the pile body and reduce the hardness of the frozen soil, so that the pile sinking operation is easier to perform, and the pile sinking efficiency is improved; and meanwhile, a cooling medium is introduced into the medium pipe, and in the descending process of the pile body, the cooling medium can freeze slurry on the side face of the pile body, so that the fixing effect on the pile body is improved, and the problem that the pile body shakes due to frozen soil melting is solved.
本发明公开了辅助冻土区预制空心桩的沉桩装置，包括有桩体，桩体内部活动安装有辅助筒，辅助筒底部通过连杆固接有可贯穿桩体底部的电热块，还包括有由辅助筒内部伸出至其外部的介质管，介质管的两端均延伸至桩体外，辅助筒上还设置有固定装置。本发明通过在桩体内部安装辅助筒和电热块，使得电热块延伸至桩体底部，在进行沉桩作业时，电热块通电并产生热量，将桩体底部的冻土融化，降低冻土硬度，使得沉桩作业更容易进行，从而提高沉桩效率；同时向介质管内部通入冷却介质，桩体在下降的过程中，冷却介质能够将桩体侧面的泥浆冷冻，从而提高对桩体的固定效果，减小冻土融化导致桩体晃动的问题。
