Connecting structure for collapsible loess slope support
The invention discloses a connecting structure for collapsible loess slope support. The connecting structure comprises a plurality of concrete lattice drainage channels arranged in a rhombus shape on the slope surface of a collapsible loess slope, wherein a hole is drilled in the vertex position of each rhombus, and a prestressed anchor rod and a collapse-resistant anchor rod are sequentially anchored in a layered staggered mode; each collapse-resistant anchor rod comprises a steel wire mesh circular pipe, concrete poured into the steel wire mesh circular pipe and pseudo-lime soil used for absorbing water in the collapsible loess slope; the length of the concrete poured into the steel wire mesh circular pipe is 1/3 of the total length of the steel wire mesh circular pipe; and the distance between the pseudo-lime soil poured into the steel wire mesh circular pipe and the slope surface of the collapsible loess slope is 10-15cm. According to the connecting structure, water in a soil body can be absorbed, the collapse amount of the soil body can be reduced, the concrete lattice drainage channels can be tied, the drainage channels are prevented from being separated from the slope body, secondary disasters are avoided, the structure is simple and firm, the strength is good, the slope body can be well prevented from sliding, and the collapsibility of the soil body can be reduced.
本发明公开了一种用于湿陷性黄土边坡支护的联结结构，包括在湿陷性黄土边坡的坡面上以多个菱形布置的混凝土格构排水渠；在每个菱形的顶点位置进行钻孔，按照分层交错的方式依次锚入的预应力锚杆和抗湿陷锚杆；所述抗湿陷锚杆包括钢丝网圆管、灌注在所述钢丝网圆管内的混凝土和用以吸收湿陷性黄土边坡中的水的三七灰土；所述钢丝网圆管内灌注的混凝土长度为钢丝网圆管总长度的1/3；所述钢丝网圆管内注入的三七灰土距离湿陷性黄土边坡的坡面10cm～15cm。本发明既能吸收土体中的水，减少土体的湿陷量，又可对混凝土格构排水渠形成拉结，避免排水渠与坡体脱离，发生二次灾害，结构简单且牢固，强度好，能够很好的阻挡坡体滑动，并能降低土体的湿陷性。
