Water-rich soil hole type spillway excavation method
The invention discloses a water-rich soil hole type spillway excavation method, which is characterized in that the whole spillway excavation section is divided into a plurality of short-distance construction units along the depth direction, so that the depth span of an actual construction end is reduced, and then each construction unit is divided into an upper layer, a middle layer and a lower layer which are sequentially supported and excavated. On the premise that the construction efficiency is guaranteed, loosening and collapsing of the upper soil body in the excavation process are further avoided; a left middle area, a right middle area, a left lower area and a right lower area are divided in the diameter-depth direction of the hole type spillway, then side-by-side supporting excavation is conducted in sequence in the diameter-depth direction, a drainage pipe is constructed in time, and soil layer loosening is further avoided; the inclined step face is constructed on the top of each construction unit, the inclined step faces of the upper layers of the adjacent construction units are sequentially connected to form the overall inclined slope face, then discharged slag in the excavation process can be rapidly discharged out of the hole type spillway along the overall inclined slope face, and timely slag discharging is achieved.
本发明公开了一种富水土壤洞式溢洪道开挖方法，通过沿着纵深方向将整个溢洪道开挖段分为若干短距离的施工单元，进而减小了实际施工端的纵深跨度，然后针对每一个施工单元分为上层、中层、下层依次支护依次开挖的方式，在保证施工效率的前提下，更进一步避免了开挖过程中上部土体的松动垮塌；通过沿着洞式溢洪道的径深方向划分左中区、右中区、左下区、右下区，然后按照径深方向依次分侧支护开挖，并及时施作排水管，进一步避免了土层松动；通过在每个施工单元的顶部施作倾斜阶梯面，并使得相邻的施工单元上层的倾斜阶梯面依次连接构成整体倾斜坡面，进而使得开挖过程中的出渣能够沿着整体倾斜坡面快速排出至洞式溢洪道的外部，实现及时排渣。
