Barrel type foundation with drag reduction system and hinge suction type penetration installation method
The invention discloses a barrel type foundation with a drag reduction system and a reaming and sucking type penetration installation method. The barrel type foundation with the drag reduction system comprises a barrel type foundation body, the drag reduction system and a negative pressure penetration system with a reaming and sucking device. The drag reduction system comprises a drag reduction barrel sleeve provided with a thixotropic slurry channel and a thixotropic slurry outlet, a thixotropic slurry pipe and a thixotropic slurry system; and resistance reduction is realized by pressing thixotropic slurry into a gap between the resistance reduction barrel sleeve and a soil body. The negative-pressure penetration system with the cutter suction device comprises the cutter suction device, a negative-pressure penetration barrel cover and a negative-pressure system, wherein the cutter suction device comprises a reamer head, a cement paste jet orifice and a high-pressure water jet orifice; the device is used for achieving negative pressure penetration, soil and stone cutter suction and soil body reinforcement. The resistance reduction system and the cutter suction device can effectively reduce the penetration resistance of the barrel type foundation, improve the penetration construction speed and are suitable for more construction terrains; the seepage stability of the bucket foundation is improved through soil reinforcement operation, and deformation and differential settlement in long-term construction are effectively controlled.
本发明公开了一种带减阻系统的桶型基础及铰吸式沉贯安装方法，带减阻系统的桶型基础包括桶型基础、减阻系统、带绞吸装置的负压沉贯系统。减阻系统包括开设有触变泥浆通道和触变泥浆出口的减阻桶套、触变泥浆管和触变泥浆系统；通过将触变泥浆压入减阻桶套与土体的缝隙中实现减阻。带绞吸装置的负压沉贯系统包括绞吸装置、负压沉贯桶盖和负压系统，且绞吸装置中含有铰刀头、水泥浆喷射口和高压水喷射口；用于实现负压沉贯、土石绞吸和土体加固。本发明的减阻系统和绞吸装置能够有效地降低桶型基础的沉贯阻力，提升沉贯施工速度且适用更多施工地形；土体加固操作提高桶型基础的渗流稳定性，有效控制了长期施工中的变形和不均匀沉降。
