Multi-isolation type anti-drag precast pile and construction method thereof
The invention discloses a multi-isolation type anti-drag precast pile and a construction method thereof, and belongs to the technical field of pile foundation construction. The multi-isolation type anti-drag precast pile comprises a precast pile body, an isolation anti-drag composite film, a fixing piece and an anti-drag coating; a drag reduction coating is arranged on the outer surface of the precast pile, the isolation drag reduction composite film is of a two-layer structure, a cavity between an inner film and an outer film is filled with a liquid drag reducer, and a non-return pressure relief hole is formed in the outer film. The isolation anti-drag composite film is fixed to the lower end of the precast pile through the fixing piece, and the overlong part of the isolation anti-drag composite film on the surface of the lower precast pile is in free lap joint with the isolation anti-drag composite film on the surface of the upper precast pile. The construction method comprises the following steps: cleaning the precast pile; preparing an isolation and resistance reduction composite film; performing hole forming operation; precast pile construction; and finishing the construction. The surface of the precast pile is covered with the isolation and resistance reduction composite film, so that the influence of settlement on the pile foundation in the construction process of a soft soil area or a soil filling area and after construction is eliminated.
本发明公开了一种多重隔离式减阻预制桩及其施工方法，属于桩基施工技术领域，包括预制桩、隔离减阻复合膜、固定件、减阻涂层；预制桩外表面设置有减阻涂层，隔离减阻复合膜为两层结构，内层膜和外层膜之间的空腔填充液态减阻剂，外层膜上设置有逆止泄压孔；固定件将隔离减阻复合膜固定在预制桩下端，下部预制桩表面的隔离减阻复合膜超长部分与上部预制桩表面的隔离减阻复合膜自由搭接。施工时按照如下方法操作：预制桩清理；隔离减阻复合膜准备；成孔作业；预制桩施工；施工完成。本发明通过在预制桩表面覆盖隔离减阻复合膜进而达到消除软土地区或者填土地区施工过程中及工后沉降对桩基础影响的问题。
