Pressure-dispersing type anchor rope

Abstract

The invention discloses a pressure-dispersing type anchor rope. The pressure-dispersing type anchor rope comprises an anchor head, at least two bearing plates arranged in anchor holes and at least two anchor rope rib sets correspondingly and fixedly connected with the bearing plates. The cross sectional areas of the anchor rope rib sets connected to the bearing plates sequentially arranged in the direction from the anchor head to the bottoms of the anchor holes are sequentially increased. According to the pressure-dispersing type anchor rope, the stress nature and the deformation nature of the materials of anchor rope ribs are used without depending on other control devices, the cross sectional areas of the anchor rope rib sets can adapt to the pressure borne by the corresponding bearing plates only by adjusting the cross sectional areas of the anchor rope rib sets connected to the bearing plates at different positions, and the effect that the pressure is evenly dispersed is achieved; the pressure-dispersing type anchor rope is simple in structure, the use cost is reduced, the total bearing capacity is effectively improved, the large and evenly-dispersed anchoring force can be provided in the geotechnical engineering supporting field, and the reliability of anchorage engineering can be improved.

Description

technical field [0001] The invention relates to a geotechnical engineering supporting device, in particular to a pressure dispersion type anchor cable. Background technique [0002] The use of pressure dispersive anchor cable support is an effective measure to control the deformation of rock and soil mass and ensure the stability of rock and soil slope. Compared with other support measures, the pressure dispersive anchor cable support has high bearing capacity, corrosion resistance and seismic performance. It has good advantages and has a good application prospect in the field of geotechnical engineering support. However, there is a shortcoming of the pressure dispersing anchor cable often used in geotechnical engineering at present, that is, after the installation of the pressure dispersing anchor cable is completed, after a certain displacement of the rock and soil mass, the pressure borne by each bearing plate is different, and the anchoring force is between The uneven d...

Problems solved by technology

Although the above two pressure-dispersing anchor cables can adjust the pressure of the bearing plates at all levels to a certain extent, so that the pressure is evenly distributed on the bearing plates at all levels, the stiffness-adjusting deformation box and the yielding anchor make the structure of the pressure-dispersing anchor cable It becomes complicated, not easy to construct, increases the cost of use, and is not conducive to popularization and application
