Excavation method for slide-resistant piles adjacent to existing road
The invention discloses a method for excavating slide-resistant piles adjacent to an existing highway, an existing side slope is arranged on one side of the existing highway, a plurality of to-be-excavated areas which are sequentially arranged are arranged on the existing side slope, and a first to-be-excavated section and a second to-be-excavated section are continuously arranged in each to-be-excavated area in the vertical direction; the method comprises the steps that excavation is conducted in a current to-be-excavated area, and a current pile hole is formed; and excavating in a target to-be-excavated area which is spaced from the current to-be-excavated area by at least two to-be-excavated areas to form a target pile hole. According to the method, excavation is carried out in the current to-be-excavated area and the target to-be-excavated area which is spaced from the current to-be-excavated area by at least two to-be-excavated areas, disturbance to a slope soil body is reduced, the slope soil body is prevented from sliding to an adjacent existing highway, the traffic influence of slide-resistant pile construction on the existing highway is reduced, and in addition, the construction efficiency is improved. Construction of the second to-be-excavated section is guided through the first to-be-excavated section, and the hole forming quality of the slide-resistant pile is improved.
本发明公开了一种邻近既有公路的抗滑桩开挖方法，所述既有公路的一侧设置有既有边坡，所述既有边坡上设置有多个依次设置的待开挖区域，各所述待开挖区域内均在竖直方向连续设置有所述第一待挖段和所述第二待挖段；所述方法包括：在当前待开挖区域内进行开挖，形成当前桩孔；在与所述当前待开挖区域间隔至少两个所述待开挖区域的目标待开挖区域进行开挖，形成目标桩孔。本发明通过在当前待开挖区域和与当前待开挖区域间隔至少两个待开挖区域的目标待开挖区域进行开挖，降低了对边坡土体的扰动，防止边坡土体滑落至邻近的既有公路，降低抗滑桩施工对既有公路的交通影响，并且，利用第一待挖段对第二待挖段的施工进行导向，提高了抗滑桩的成孔质量。
