Composite pile structure capable of weakening negative friction influence and construction method
The invention discloses a composite pile structure capable of weakening the influence of negative friction resistance and a construction method, solves the problem that a composite pile structure in the prior art suffers from negative friction resistance, and has the beneficial effect of effectively transferring the negative friction resistance suffered by a pile body, and the specific scheme is as follows: the composite pile structure capable of weakening the influence of the negative friction resistance comprises a cast-in-place pile, the top of the cast-in-place pile is connected with a precast pile, the precast pile is sleeved with an annular first component in the annular direction, at least one first concave part is arranged on the outer surface of the precast pile, each first concave part is provided with a first tooth-shaped track, the first tooth-shaped tracks are arranged in the height direction of the precast pile, and second concave parts are arranged on the inner surface of the first component. A first tooth-shaped track is arranged in the first concave part, a second tooth-shaped track is arranged in the second concave part, the first tooth-shaped track and the second tooth-shaped track are oppositely arranged, a plurality of tooth-shaped components are supported between the first tooth-shaped track and the second tooth-shaped track in a matched mode, and the precast pile movably supports the tooth-shaped components.
本发明公开了一种能够减弱负摩阻力影响的复合桩结构及施工方法，解决了现有技术中复合桩结构受负摩阻力的问题，具有有效转移桩身所受负摩阻力的有益效果，具体方案如下：一种能够减弱负摩阻力影响的复合桩结构，包括灌注桩，灌注桩的顶部连接有预制桩，预制桩的环向套有环形的第一构件，预制桩外表面设置至少一处第一凹部，每一第一凹部均设置第一齿状轨道，第一齿状轨道沿着预制桩的高度方向设置，第一构件内表面设置第二凹部，第二凹部内设置第二齿状轨道，第一齿状轨道与第二齿状轨道相对设置，第一齿状轨道与第二齿状轨道之间契合支撑若干齿状部件，预制桩活动支撑齿状部件。
