A kind of prestressed anchor cable structure and prestressed anchor cable construction method

Abstract

The application relates to a prestressed anchor cable structure and a prestressed anchor cable construction method, including an anchor cable and a grouting pipe. An anchor cable hole is opened in the soil layer, and both the anchor cable and the grouting pipe are partially located in the anchor cable hole. The end of the anchor cable is fixedly connected with a fixed block, and an inner cavity is opened in the fixed block, and a plurality of strip-shaped holes are opened on the inner wall of the inner cavity, and a fixed assembly is arranged in the inner cavity, and the fixed assembly includes a moving plate, a first spring and a plurality of oblique rods, the movable plate is slidably connected to the inner side wall of the inner cavity, and the plurality of oblique rods are set in correspondence with the plurality of strip holes, one end of the oblique rod is hinged on the movable plate, and the other end of the oblique rod can pass through the The strip-shaped hole abuts against the inner wall of the anchor cable hole, one end of the first spring is fixedly connected to the bottom wall of the inner cavity, and the other end of the first spring is fixedly connected to the moving plate; The first push assembly corresponds to each slant rod, and a second push assembly for changing the inclination angle of the slant rod is arranged in the inner cavity.

Description

technical field [0001] The present application relates to the technical field of civil engineering, and in particular, to a prestressed anchor cable structure and a prestressed anchor cable construction method. Background technique [0002] In general areas with complex geological conditions, high slopes are often supported by the method of "prestressed anchor cables + lattice beams" to ensure the stability of high subgrade slopes. After the prestressed anchor cable is installed, it needs to be grouted through the pre-buried grouting pipe. The grouting adopts cement mortar. After the comparison and selection of the test, the construction mix ratio is determined. Refill the grout until it is full. [0003] For related technologies, refer to the Chinese invention patent with the authorized announcement number CN110453695A, which discloses a prestressed anchor cable structure and a one-step grouting construction method for the prestressed anchor cable, including anchor cable h...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: the grouting pipe needs to be gradually extracted during the grouting process, but in the process of extracting the grouting pipe, the anchor cable may be dragged to move at the same time, thereby affecting the grouting process. The stability of the middle anchor
