Round diaphragm wall foundation pit excavation and pouring method
According to the excavation and pouring method for the circular diaphragm wall foundation pit, full coverage of the working face of the foundation pit is achieved through a rotatable gantry truss, and a hoisting appliance is arranged on the gantry truss, so that the hoisting appliance is matched with the gantry truss to walk to any position in the foundation to hoist earthwork, and then the earthwork is hoisted and operated to the roof of an earthwork vehicle outside the foundation to unload the earthwork; according to the method provided by the invention, the unearthing operation at any point in the foundation pit range can be realized, compared with a traditional deslagging mode, the whole unearthing process is safe, efficient and economical, in addition, after the foundation pit excavation is completed, a concrete conveying pipe can be arranged on the gantry truss, the concrete conveying pipe can be arranged on the gantry truss, and the operation is convenient. The device is used for distributing and pouring the super-large-size core filling concrete of the foundation pit, the investment is further saved, and the pouring construction difficulty of the super-large-size core filling concrete is further reduced.
本发明为一种圆形地连墙基坑开挖、浇筑方法，利用可旋转的龙门桁架实现基坑作业面全覆盖，在龙门桁架上布置吊装器具，这样吊装器具配合龙门桁架就可以行走至地基内的任意位置吊装土方，然后起吊、运行至地基外土方车车顶上卸土，卸土完成后，吊装器具又运行至地基内再次吊装土方，本发明提供的方法可实现基坑范围内任一点位的出土作业，相较于传统的出渣方式，整个出土过程安全、高效、经济，此外，在基坑开挖完成后，还可以在龙门桁架上设置混凝土输送管，用于对基坑超大体积填芯砼布料和浇筑，进一步节约投入和降低超大体积填心砼的浇筑施工难度。
