Building jacking underpinning device and method
The invention aims to provide a building jacking underpinning device and method. The building jacking underpinning device comprises a supporting plate beam and a plurality of jacking underpinning structures, wherein the supporting plate beam surrounds the periphery of the bottom of a building foundation wall and is used for supporting the protective building; each jacking underpinning structure comprises an anchor rod static pressure pile, a jacking counter-force beam, a jacking steel beam, a jacking steel stand column and a jack, the jacking steel stand column and the jacking steel beam forma jacking frame, the jacking counter-force beam and the anchor rod static pressure pile form a counter-force supporting system. In the jacking stage, the jack pulls the jacking steel stand column through the jacking steel beam, meanwhile, the supporting plate beam is pulled for synchronous jacking, the jacking counter-force beam provides counter-force support for the jack, and force is transmittedto the anchor rod static pressure pile; in the stage of replacing a cushion block at the lower part of the jack, a hydraulic jack and a following jack replace the lower cushion block in turn; and theoperations are repeated until the building reaches the designed jacking height. According to the device, jacking underpinning of the building can be completed at +/- 0.000 or above, the outer vertical face of the building is not damaged, and safety and stability are achieved.
本申请的目的是提供一种建筑顶升托换装置及方法，包括托盘梁和多个顶升托换结构，所述托盘梁围绕在建筑基础墙体底部的四周，用于托住保护性建筑；每个顶升托换结构包括锚杆静压桩、顶升反力梁、顶升钢梁、顶升钢立柱及千斤顶，顶升钢立柱和顶升钢梁构成顶升框架，顶升反力梁和锚杆静压桩构成反力支撑体系，在顶升阶段，千斤顶通过顶升钢梁去拉动顶升钢立柱，同时拉动托盘梁同步顶升，而顶升反力梁提供千斤顶的反力支撑，将力传递给锚杆静压桩；在更换千斤顶下部垫块阶段，液压千斤顶和跟随千斤顶轮流更换下部垫块；重复以上操作，直至建筑达到设计顶升高度。本装置可以实现建筑在±0.000以上完成顶升托换，不破换建筑的外立面，安全稳定。
