Soft soil deep foundation pit hydraulic impact excavation type earth excavation method
The invention provides a soft soil deep foundation pit hydraulic impact excavation type earth excavation method which comprises the following steps: (1) constructing an enclosure structure for enclosing a foundation pit at an excavation position of the foundation pit, and arranging a mast crane foundation on the side of the excavation position of the foundation pit; (2) a mud flushing assembly is arranged at the excavation position of the foundation pit, a mud settling pond is arranged on the side of the excavation position of the foundation pit, a mud conveying assembly is arranged between the mud flushing assembly and the mud settling pond, a soil body located at the excavation position of the foundation pit is flushed through the mud flushing assembly, so that the soil body forms mud, and the mud is pumped into the mud settling pond through the mud conveying assembly; the foundation pit excavation position is excavated to the preset depth through hydraulic scouring, and a foundation pit is formed; and (3) a mast crane is arranged on the mast crane foundation, and the side slope on the side edge of the foundation pit is excavated through a grab bucket of the mast crane. The method has the advantages of being convenient to construct, short in construction period, large in construction depth and area, low in construction cost, simple in process and high in construction safety.
本发明提供了一种软土深基坑水力冲挖式土方开挖方法，包括以下步骤：(1)在基坑开挖位置施工用于对基坑进行围护的围护结构，在基坑开挖位置的侧方设置桅杆起重机基础；(2)在基坑开挖位置上设置冲泥组件，在基坑开挖位置的侧方设置泥浆沉淀池，在冲泥组件与泥浆沉淀池之间设置输泥组件，通过冲泥组件冲刷位于基坑开挖位置的土体，使得土体形成泥浆，通过输泥组件将泥浆抽送至泥浆沉淀池内，从而在基坑开挖位置上水力冲刷开挖至预设深度并形成基坑；(3)在桅杆起重机基础上设置桅杆起重机，通过桅杆起重机的抓斗对基坑侧边的边坡进行挖除。本发明具有施工方便、工期短、施工深度和面积大、施工成本低、工艺简单和施工安全性高的特点。
