Connecting structure for collapsible loess slope support

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of side slope support, and in particular relates to a connection structure for collapsible loess side slope support. Background technique [0002] In recent years, with the development of the economy and the improvement of people's requirements for the living environment, my country's construction and municipal projects have developed rapidly. Many cities build residential projects, and there is no shortage of project sites near slopes. Slopes with ordinary geology can be treated with anchor-spray support, gravity retaining wall, and slope ratio method, but in collapsible loess areas, conventional treatment methods are somewhat lacking. [0003] The main feature of collapsible loess is its water subsidence. Loess mostly exists in dry areas with little rain. The water in the loess evaporates, and solidification cohesion occurs in the soil, which prevents the compaction of the upper soil to the lower soil, fo...

Problems solved by technology

However, for collapsible loess, once the loess is submerged in water, it will form negative frictional resistance to the support systems such as anchor rods and reduce its anchorage. grid detachment, making the grid protection structure become a new dangerous body
