Trapezoid drainage slide-resistant pile with pile with additional toe and construction method thereof
The invention discloses a trapezoid drainage slide-resistant pile with a pile with an additional toe and construction method thereof. The trapezoid drainage slide-resistant pile with the pile with theadditional toe is characterized in that the overall cross section of a pile body is trapezoid, the short side surface of the pile body is a soil backing surface, the long side surface of the pile body is a soil facing surface, the pile body is divided into a bottom solid pile body with the additional toe, a lower solid pile body and an upper hollow pile body, the sectional area of the upper hollow pile body is not constant, the sectional area of the upper hollow pile body is gradually reduced from bottom to top, three water collecting spaces are formed in the hollow pile body, the water collecting spaces are connected with a soil facing surface sliding body through water collecting holes, the sectional area of the solid pile body is constant, a drainage cushion layer is arranged at the junction between the solid pile body and the hollow pile body, water diversion holes and drainage holes are formed in the drainage cushion layer, water is drained into a soil facing surface sliding bedthrough the drainage holes, the water collecting spaces, the water diversion holes and the drainage holes are filled with permeable aggregate, and the bottom solid pile body with the additional toe expands all around and has a certain thickness. According to the trapezoid drainage slide-resistant pile with the pile with the additional toe, the soil arching effect can be triggered through the trapezoid cross section shape, the anti-overturning capacity can be improved through the pile with the additional toe, the water content of a sliding body is reduced through self water collection and drainage, and compared with a traditional slide-resistant pile, the material consumption is less.
本发明为一种梯形加趾排水抗滑桩及其施工方法，桩体整体横截面为梯形，短边面为背土面，长边面为迎土面，桩体分为底部实心加趾，下部实心桩体，上部空心桩体，上部空心桩体截面积不恒定，自下向上截面积逐渐缩小，空心桩体内设有3个集水空间，集水空间与背土面滑体通过集水孔连接，实心桩体截面积恒定，其与空心桩体交界处设有排水垫层，排水垫层内设有引水孔和排水孔，通过排水孔将水排向迎土面滑床中，集水空间、引水孔、排水孔中均填充透水骨料，底部实心加趾向四周扩大，且具有一定厚度。本发明可通过梯形截面形状触发土拱效应，通过加趾提高抗倾覆能力，通过自集水排水降低了滑体含水量，并且较传统抗滑桩用料更少。
