Method for treating landslide of accumulation layer
The invention discloses a method for treating landslide of an accumulation layer. A micro pile structure comprises a plurality of micro piles, wherein the bottom of each micro pile is used for being inserted into a sliding bed; the micro piles are arranged in a manner that a plurality of rows are parallel and staggered; each micro pile comprises a pile body, a grouting steel sleeve, a plurality of prestress anchor rods, a piece of I-shaped steel and a crown beam; the pile body is a concrete filled steel tube pile; the grouting steel sleeve coaxially sleeves the outer side of the lower part of the pile body; a plurality of through holes are uniformly distributed in the circumferential surface of the grouting steel sleeve; the through holes communicate with the inside of the pile bodies; each prestressed anchor rod obliquely penetrates through the top of the pile body close to the slope surface of a slip mass, and is inserted into the sliding bed; the I-shaped steel is used for connecting the prestressed anchor rods on the micro piles in the same row; and the crown beam is connected with the top of each micro pile in a pouring manner. The problem that in the prior art, a miniature pile group can be damaged due to too large shearing force generated by landslide is solved.
本发明公开了一种用于堆积层滑坡治理的方法，微型桩结构，包括：多根微型桩，各个微型桩的底部用于插入滑床中，各个微型桩的布局方式为平行设置多行、各行错位排列；每个微型桩包括：一桩体，其为钢管混凝土桩；一注浆钢套，同轴套设在桩体下部外侧，注浆钢套的圆周面上均匀布设多个通孔，通孔与桩体内部贯通；多根预应力锚杆，每根预应力锚杆分别从靠近滑体坡面的桩体顶部斜插穿过，并插至滑床中；一根工字钢，将位于同一行的各个微型桩上的预应力锚杆连接；一冠梁，浇筑连接各个微型桩的顶部。解决了现有技术中微型桩桩群可能会因为滑坡产生的过大剪力导致桩群破坏的问题。
