Foundation pit earth excavation method
The invention relates to a foundation pit earth excavation method, and belongs to the field of building construction. The method comprises the steps that the area of a construction site is measured, and a foundation pit excavation area is divided according to a drawing; a continuous support wall is driven along the periphery of the foundation pit; a first layer of earthwork is excavated in the middle; after a first excavator working face is excavated on the first layer of earthwork, and an excavator enters the first excavator working face and excavates the first layer of earthwork from the first excavator working face to the periphery; a second layer of earthwork is excavated downwards in the middle of the first excavator working face, a second working face is excavated, and the excavator enters the second excavator working face and excavates the second layer of earthwork towards the periphery; a plank road is arranged for the excavator and an earthwork vehicle to enter and exit the foundation pit; and after the earthwork of the foundation pit is excavated and all vehicles drive out of the foundation pit, the plank road is dismantled from the supporting wall. The plank road is arranged on the supporting wall, namely the periphery of the foundation pit, and compared with a ramp built by soil, the plank road does not interfere with horizontal support and normal earth cutting work of the excavator.
本申请涉及一种基坑土方开挖方法，属于建筑施工的领域。其包括测量施工地面积，并根据图纸划分出基坑开挖区域；沿基坑四周打入连续的支护墙；并在中间开挖第一层土方；在第一层土方挖出第一挖机工作面后，挖机进入第一挖机工作面，在第一挖机工作面向四周开挖第一层土方；在第一挖机工作面的中间向下开挖第二层土方，并挖出第二工作面，挖机进入第二挖机工作面并向四周开挖第二层土方；设置栈道供挖机和土方车进出基坑；当基坑的土方均开挖完后，等所有的车辆均开出基坑后，将栈道从支护墙上拆除。栈道设在支护墙上，也即是基坑的四周，与土堆砌的坡道相比，不会妨碍水平支护，也不会干扰挖机的正常挖土工作。
