Background
In the field of slope support, a flexible slope protective net, a prestressed anchor cable frame and an anti-slide pile are widely applied, and particularly, the prestressed anchor cable plays a very key role in foundation pit support and landslide control engineering.
The prestressed anchorage cable is through arranging the prestressed anchorage cable anchor section in secret stable ground to whole anchor rope implementation anchor, and this means traditional prestressed anchorage cable must the downward sloping just can make the prestressed anchorage cable pass unstable gliding mass as early as possible and get into stable ground and implement the anchor to the free end of prestressed anchorage cable passes the gliding mass, and the upper end anchor is in domatic engineering structure, and this just means can produce following drawback:
on one hand, when a steep dip angle sliding surface is generated on a deep foundation pit or a newly excavated slope surface, the component force of the pulling force generated by the downward inclined anchor cable to the sliding surface of the sliding body is very small, even possibly negative, so that the sliding resistance generated by the downward inclination of the slope surface is very small, even the sliding resistance is very easy to lose efficacy, and the treatment effect is very poor.
On the other hand, the free sections of the prestressed anchor cables distributed in the landslide body do not restrict the movement of the landslide body, so that the prestressed anchor cables only can act on the landslide body through the anti-skid engineering structure anchored on the ground surface, the load of the anti-skid engineering structure cannot be well reduced, the anti-skid engineering is large in size, and the manufacturing cost is high.
In order to solve the problems, a new solution is provided for a suspension cable-shaped and inclined-pull-shaped composite flexible slope anchoring structure (2021106450505, 2021212891924), and the defects of the traditional anchor cable are overcome by combining an inclined secondary anchor beam and slope engineering.
However, the above solution still has the following problems:
1. the secondary anchor beams are mainly distributed near the ground surface, and when the ground surface is poor in smoothness and large abrupt change occurs in the terrain, the anchor beams are difficult to span the abrupt change;
2. the secondary anchor beam is not provided with an anchoring section of the secondary anchor beam before being connected with the slope surface anti-skidding project of the front edge of the landslide, so that the reduction of the anti-skidding force of the slope surface anti-skidding project is limited;
3. the suspension cable-shaped and inclined pull-shaped anchor beams are not necessarily suitable for all projects, and part of deep foundation pit projects or slope projects do not have conditions.
Therefore, a new solution is needed to solve the above problems.
