Description

Temporary landslide prevention structure of collapsing of highway bank protection

Technical Field

The utility model belongs to the technical field of highway construction, and particularly relates to a temporary anti-landslide collapse structure for highway revetment.

Background

Road slope protection forms are various, and rubble bank protection is usually grouted in mountain road sections, and for road sections with large slopes and unsatisfactory geological conditions, an active protective net or a passive protective net is arranged above the road sections in a matched mode to prevent collapse and landslide of mountain rock soil beside roads in rainy seasons.

However, as time goes on, in rainy seasons, particularly in continuous rainy days, when the rainwater infiltration amount is large, the upper protective net can protect the falling rocks, but the lower grout rubble protection slope has the condition that blocks are washed to the couch, the small collapse cannot be managed in time, the larger the grout rubble around the protection net is, the more the grout rubble around the protection net is washed, the further the grout rubble around the protection net is, the continuous collapse can be rapidly expanded in a region with a loose geological structure, and even a landslide is formed.

In prior art, almost blank to the improvement of similar hazardous area, consider that administers personnel's safety, generally construct when waiting weather condition and geological conditions all suitable again, nevertheless to the comparatively gentle mountain area highway section of slope, similar grout rubble bank protection occasional small-size collapses, be through artifical striking plate or compaction protection cloth and do the processing temporarily, under guaranteeing that the highway section is unobstructed, driving safety prerequisite wait weather and geological conditions under and administer the construction again after normal.

However, this operation method has the following inconveniences:

1. both the manual guard plate beating and the compaction guard cloth need to be nailed to penetrate through the surface layer of the mortar rubble, but when the rain falls continuously, the soil on the inner layer is loose, the stress is almost completely on the surface layer of the mortar rubble after nailing, nails cannot be eaten after the nailing of the slope protection for a long time, and the nailing area is cracked, even the mortar rubble collapse area becomes larger;

2. the labor intensity of operators is high, about 100cm of collapse area needs to be enlarged by at least 50cm towards the periphery, multiple nailing positions are needed in the area, the operators need to construct on slope protection slopes in the rain, and the operation difficulty and the operation intensity are high.

Based on the above technical problems, the skilled person in the art proposes a temporary anti-landslide collapse structure for road slope protection.
