Pile repairing reinforcing and pre-pressing jacking structure and construction technology
The invention discloses a pile repairing reinforcing and pre-pressing jacking structure and a construction technology, and relates to the technical field of building engineering foundation reinforcing construction, the structure comprises original cast-in-place piles, an original bearing platform and a building superstructure, a new reinforcing bearing platform is formed on the periphery of the original bearing platform due to the fact that the cross section of the original bearing platform is increased for reinforcing, and two new cast-in-place piles are arranged below the new reinforcing bearing platform; first jacks are installed between the two new cast-in-place piles and the new reinforcing bearing platform respectively, a cut-out section is arranged in the middle of the original cast-in-place pile, and a second jack is installed in the cut-out section after pile cutting; according to the construction technology, a space is reserved between the top of the newly-added reinforcing cast-in-place pile and the newly-added reinforcing bearing platform, a jack is installed and pre-pressed, in this way, it can be guaranteed that the newly-added reinforcing cast-in-place pile and an original pile foundation work cooperatively, the load of the original pile foundation is reduced, and uneven settlement of an existing building is effectively stopped.
本发明公开了一种补桩加固与预压顶升的结构及施工工艺，涉及建筑工程基础加固施工技术领域，结构包括原灌注桩、原承台和建筑上部结构，原承台因增大截面加固而在周边形成新加固承台，新加固承台的下方设置有两个新灌注桩，两个新灌注桩与新加固承台之间分别安装有第一千斤顶，原灌注桩的中部设置有截取段，截桩后，在截取段的内部安装有第二千斤顶；施工工艺通过在新增加固灌注桩顶与新加固承台之间先预留空间，安装千斤顶并对其进行预压处理，这样才能保证后新加固灌注桩与原有桩基协同工作，降低原有桩基荷载，有效制止既有建筑不均匀沉降。
