Foundation pit earth excavation method
The invention relates to a foundation pit earthwork excavation method which comprises the following steps: after paying-off measurement of a deep foundation pit is completed, N layers of horizontal supporting steel plates are designed in the deep foundation pit from top to bottom according to the engineering condition of the deep foundation pit, and foundation pit earthwork is excavated layer by layer by adopting an island type excavation method, N is greater than or equal to 1 and less than or equal to 20; outer side steel sheet piles are driven downwards along the wall of the deep foundation pit; earthwork above the first-layer horizontal supporting steel plate is excavated, one end of the first-layer horizontal supporting steel plate is welded to the outer-side steel plate pile, and the inner-side steel plate pile is downwards driven into the other end of the first-layer horizontal supporting steel plate; and in the same way, the Nth layer of horizontal supporting steel plate is constructed, a ramp is built, earthwork below the Nth layer of horizontal supporting steel plate is excavated, and deep foundation pit earthwork excavation is completed. The construction method is simple and easy to implement, trestles are not needed, the construction period is effectively shortened, the deep foundation pit earth excavation cost is reduced, and the deep foundation pit earth excavation method is safe and reliable.
本发明涉及一种基坑土方开挖方法，包括深基坑放线测量完毕后，根据深基坑工程情况在深基坑内由上到下设计N层水平支撑钢板并采用岛式开挖法逐层开挖基坑土方，1≤N≤20；沿深基坑壁向下打入外侧钢板桩；开挖第一层水平支撑钢板以上的土方，将第一层水平支撑钢板一端与外侧钢板桩焊接，在第一层水平支撑钢板的另一端向下打入内侧钢板桩；以此类推施工第N层水平支撑钢板，修建坡道并开挖第N层水平支撑钢板以下的土方，深基坑土方开挖完毕。本发明施工方法简单易行，无需栈桥、有效加快施工工期，降低了深基坑土方开挖成本，是一种安全可靠的深基坑土方开挖方法。
