Composite pile sinking and construction method thereof
The invention provides composite pile sinking. The composite pile sinking comprises a steel pipe pile and a high-pressure jet grouting pile arranged on the lower portion of the steel pipe pile, wherein the high-pressure jet grouting pile comprises a high-pressure jet grouting pile bonding section and a high-pressure jet grouting pile expanding section. The invention further provides a construction method of the composite pile sinking. According to the composite pile sinking and the construction method thereof, a part of the steel pipe pile is replaced with an expanding cement soil pile, the vertical bearing capacity of a composite pile foundation is effectively improved, the length and the inserting and beating difficulty of the steel pipe pile are greatly reduced, later-period rapid pulling-out and transferring can be achieved, and the beneficial effects of being clear in stress, convenient and fast to construct, safe and stable are achieved.
本发明提供一种复合沉桩,包括：钢管桩；高压旋喷桩，设于所述钢管桩的下部；所述高压旋喷桩包括高压旋喷桩粘结段和高压旋喷桩扩伸段。本发明还提供一种复合沉桩的施工方法。本发明采用扩径的水泥土桩代替部分钢管桩，有效提高了复合桩基的竖向承载力，大大减少了钢管桩的长度及插打难度，可实现后期快速拔除和周转，具有受力明确，施工便捷，安全稳定的特点。
