Pile lagging foundation and construction method thereof
The invention discloses a pile lagging foundation and a construction method thereof, and belongs to the technical field of building foundation construction. Comprising a bearing platform, a pile body and a pile force-removing device, the bearing platform is arranged above the pile body, the bearing platform and the pile body are connected through the pile force-removing device, the pile force-removing device is of a hollow structure, and the top of the pile body is covered with a mattress layer. The top of the pile body and the mattress layer extend into the pile force-removing device from the lower end of the pile force-removing device and can move up and down relatively. Compared with the prior art, the method has the advantages that the pile force-removing device is arranged between the pile top and the bearing platform, foundation soil is pre-pressed by structural construction loads, the bearing capacity of the soil is effectively utilized, when foundation settlement deformation reaches a set allowable value, variable stiffness is adopted to reduce foundation settlement, post-construction settlement is effectively reduced, and the construction efficiency is improved. Therefore, a traditional bearing capacity control design method is changed, and the foundation design target of geotechnical engineering with deformation control as a main part and bearing capacity control as an auxiliary part is achieved.
本发明公开了一种桩滞后地基及其施工方法，属于建筑地基施工技术领域。包括有承台、桩体、桩脱力器，所述承台设置在桩体的上方，且承台与桩体之间通过桩脱力器连接，所述桩脱力器为内部中空的结构，桩体的顶部覆盖有一层褥垫层，所述桩体的顶部及褥垫层均伸入到从桩脱力器的下端伸入到桩脱力器内并能够相对上下活动。本发明的优势在于，相比于现有技术：本发明通过在桩顶与承台之间设置桩脱力器，实现结构施工荷载对地基土进行预压，有效利用土的承载力，当地基沉降变形达到设定的允许值时，采用变刚度减少地基沉降，有效减少工后沉降，从而改变了传统的承载力控制设计方法，实现了岩土工程的以变形控制为主、承载力控制为辅的地基设计目标。
