Construction method of stretching type anchor plate uplift pile
The invention discloses a construction method of a stretching type anchor plate uplift pile. The construction method comprises the following steps that S1, an anchor plate is made according to the bearing pressure F of a construction soil layer; s2, an anchor plate assembly is assembled according to the anchor plates made in the step S1, and the anchor plate assembly is driven into a designed soil layer through a driving part; s3, the anchor plate is unfolded through the driving part; and S4, concrete is poured into the frame. The anchor plate is made, pressed into the deep dense soil layer and then stretched into the tensile anchor plate, after prestress is applied to the pile body, the anchor plate bears most of upward pulling force, the pile body stress is pressure stress and the pulling force, the stress of soil around the pile close to the raft plate is small, the stress is larger towards the lower soil layer, the deep dense soil layer of the anchor plate section bears most of pressure, and the pile body stress is larger. The more the soil layer is pressed, the harder the soil layer is, the compression resistance of the deep soil layer is fully exerted, the deeper the anchor plate is embedded into the soil layer, the larger the section of the end anchored into the hard soil layer is, the larger the provided uplift bearing capacity is, and the durability and the deformation resistance are high.
本发明公开了一种伸展式锚板抗拔桩的施工方法，包括以下步骤：S1、根据施工土层的承压力F下制定锚板；S2、根据步骤S1中制定好的锚板组装锚板组件，并通过驱动件将锚板组件打入设计土层；S3、通过驱动件将锚板展开；S4、将框架内浇灌混凝土。本发明通过制定锚板，压入深层密实土层后伸展开为抗拉锚板，桩身施加预应力后，锚板承受大部分上拔力，桩身应力为压应力，拉拔力作用下，桩周土体应力近筏板处较小，越向下部土层应力越大，锚板段深部密实土层承担大部分压力，土层越压越硬，充分发挥了深层土层的抗压性能，锚板埋入土层越深，锚入坚硬土层端部截面越大，提供的抗拔承载力越大，并且耐久性好，抗变形能力强。
