Construction method of structure for improving bearing capacity of pile foundation of wharf
The invention discloses a construction method of a structure for improving the bearing capacity of a wharf pile foundation. According to the structure for improving the bearing capacity of the wharf pile foundation, after holes are drilled in a soil body around the wharf pile foundation, cement paste is poured into the holes, the cement paste and the soil body are mixed to form a jet grouting consolidation body, the jet grouting consolidation body and the wharf pile foundation are compactly combined, and the bearing capacity of the pile foundation is improved; the structure for improving the bearing capacity of the wharf pile foundation comprises the wharf pile foundation, an operation platform, a drilling system, a grouting system, a grouting hole, grouting slurry and a jet grouting consolidation body. The wharf pile foundation is positioned below the pile top bearing platform and the beam system; the operation platform is arranged between wharf pile foundations and located below a pile top bearing platform and a beam system. The drilling system and the grouting system are both located on the operation platform. The jet grouting consolidation body is located on the periphery of the wharf pile foundation; the effective forming radius of the jet grouting consolidation body is larger than or equal to 500 mm. The method has the advantages that the bearing capacity of the wharf pile foundation put into operation is improved, and the engineering cost is saved.
本发明公开了一种提高码头桩基承载力结构的施工方法。它采用提高码头桩基承载力结构在码头桩基周围的土体内钻孔后、灌入水泥浆，使水泥浆与土体混合形成旋喷固结体，旋喷固结体与码头桩基致密结合、提高桩基的承载力；提高码头桩基承载力结构包括码头桩基、操作平台、钻孔系统、灌浆系统、注浆孔、注浆浆液和旋喷固结体；码头桩基位于桩顶承台及梁系下方；操作平台布置在码头桩基之间，位于桩顶承台及梁系下方；钻孔系统、灌浆系统均位于操作平台上；旋喷固结体位于码头桩基外周；旋喷固结体的有效形成半径大于或等于500mm。本发明具有提高已经投入运行的码头桩基的承载力，节约工程成本的优点。
