Pile foundation ballasting device and application thereof
The invention relates to a pile foundation ballasting device and application thereof. The pile foundation ballast device comprises a bearing steel frame which is provided with a longitudinal beam extending in the longitudinal direction of a pilot tunnel above a pile group and a plurality of cross beams which can be connected to the upper edge of the longitudinal beam and stretch across the pilot tunnel to be erected; the jack is suitable for being arranged above a foundation pile to be loaded and is supported between the lower edge of the longitudinal beam and the top surface of the foundation pile; the two ends of the cross beam can be connected to the side wall of the pilot tunnel through force transmission pieces correspondingly, so that when the jacks apply acting force to the foundation piles downwards, the pressure of earthwork on the two sides of the pilot tunnel is transmitted to the force application positions of the jacks through the bearing steel frame, and the counter-acting force of the earthwork on the peripheries of the foundation piles is at least partially balanced. By means of the device, pre-pressing acting force is applied to the pile foundation after pile foundation construction is completed, and sedimentation of the pile foundation in the follow-up construction stage and in the use process of a completion station can be greatly reduced.
本发明涉及桩柱基础压载装置及其应用。在此，提供一种桩柱基础压载装置，其包括：承载钢架，具有一个在桩群上方沿着导洞纵向延伸的纵梁和多个能够连接于该纵梁的上缘并横跨导洞架设的横梁；千斤顶，适于设置在待加载的基桩的上方并且支承于纵梁的下缘与基桩的顶面之间；其中，横梁的两端分别能够通过传力件连接于导洞侧壁，使得当千斤顶向下对基桩施加作用力时，导洞两侧土方的压力经由承载钢架被传导至千斤顶施力位置，以至少部分平衡基桩外围土方的反作用力。利用本发明的装置，在桩基施工完成后对其施加预压作用力，可以大大减少桩基在后续施工阶段以及竣工车站使用当中的沉降。
