Foundation structure loading processing method and method for building subway station through hole pile method
The invention relates to a foundation structure loading processing method and a method for building a subway station through a hole pile method. The method for carrying out loading treatment on the foundation structure in the hole pile method underground engineering construction comprises the steps that a ballast device comprising a bearing steel frame and a jack is provided, and the bearing steel frame is provided with at least one cross beam which can stretch across a pilot tunnel to be erected and installed; a ballast device is arranged in the pilot tunnel, the two ends of the cross beam are connected to the side wall of the pilot tunnel through force transmission pieces correspondingly, and a jack is placed and supported between the cross beam and the top face of the vertical supporting component; and vertical loading pressure is applied to the vertical supporting component above the vertical supporting component through the jack, the settling volume of the top face of the vertical supporting component is measured, and the maximum value of the loading pressure is 1.0-2.0 times of the designed bearing pressure of the vertical supporting component. According to the method, on the basis of the technological characteristics of hole pile method construction, detection and acceptance inspection of the pile foundation or the foundation pile are integrated in the treatment technology of the construction process, and maximization of efficiency and benefits can be achieved.
本发明涉及基础结构加载处理方法和用洞桩法建造地铁车站的方法。在此，提供一种在洞桩法地下工程施工中用于对基础结构进行加载处理的方法，包括：提供包括承载钢架和千斤顶的压载装置，承载钢架具有至少一个能够横跨导洞架设安装的横梁；在导洞内安置压载装置，将横梁的两端分别通过传力件连接于导洞侧壁，并将千斤顶放置和支承于横梁与竖向支撑构件顶面之间；通过千斤顶在竖向支撑构件上方对其施加竖向的加载压力，并测量竖向支撑构件顶面的沉降量，该加载压力的最大值为竖向支撑构件的设计承载压力的1.0至2.0倍。按照本发明，基于洞桩法施工的工艺特点，在施工过程处理工艺之中整合了对桩基或基桩的检测验收，可达到效率和效益的最大化。
