Embodiment 1

[0037] A large-tonnage anchor cable in a combination of tension and compression load-bearing mode and a method for making and installing it. The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0038] Such as figure 1 and figure 2 As shown, a large-tonnage anchor cable in a combined tension-compression bearing mode includes a tension anchor section 18, a pressure anchor section 17 and a free section 16 from bottom to top, and the tension anchor section 18 is used as a pressure bearing body for the pressure anchor section 17. , the steel strands of the tension anchoring section 18 are stripped of plastic outsourcing and grease, and the tension anchoring section 18 includes a shear pin 3, a pressure bearing plate 6 and a cone-shaped guide head 4 from top to bottom, and the shear pin 3 is set On each bundle of steel strands, the shear pins 3 are hollow cylindrical, and the steel strands pass t...

Abstract

The invention relates to a pulling and pressing combined bearing manner large-tonnage anchor cable and a manufacturing and installing method. The anchor cable is composed of a tension anchoring segment, a pressure anchoring segment and a free segment. The tension anchoring segment comprises a shearing force pin and a bearing plate from top to bottom. The shearing force pin is arranged on a steel strand, and the bearing plate is provided with a plurality of steel strand holes and injected holes in the axis direction. Soft steel fixing keys are inserted and fixed to the upper ends and the lower ends of the steel strand holes. The soft steel fixing keys are provided with soft steel fixing key holes, and the tail end of the steel strand penetrates the soft steel fixing key holes and is in tight fit with the soft steel fixing key holes. By means of the shearing force pin and the bearing plate, the connection strength of the anchor cable and cement mortar is enhanced, sufficient anchoring between the anchor cable and mortar is guaranteed, the length of the anchoring segment is effectively reduced, and 15%-20% discount, caused by the fixing manner of 180-degree turning of the anchor strand in a traditional pressure type anchor cable, of the anchor cable strength is avoided. The large-tonnage anchor cable is large in bearing force and can be widely applied to foundation trenches, side slopes and other rock anchor engineering fields.

Description

technical field [0001] The invention belongs to the field of rock-soil anchoring engineering, and in particular relates to a large-tonnage anchor cable in a combined tension-compression bearing mode and a method for making and securing it. Background technique [0002] In rock and soil anchoring projects such as foundation pits and slopes, anchor cables are widely used. The existing anchor cables mainly include pressure type anchor cables and tension type anchor cables according to the stress characteristics, each with its own characteristics. According to the characteristics of different geological conditions, different types of anchor cables are selected. Existing anchor cables are drilled after the excavation face is excavated, steel strands are placed in the drilled holes, and then cement mortar is poured into the drilled holes through the grouting pipe for anchoring. The tension type and pressure type anchor cables pass the anchoring force to the cement mortar of the ...
