Description

Prestressed anchor cable device Technical Field The utility model relates to the technical field of anchor cable devices, in particular to a prestressed anchor cable device. Background The anchor cable is used for reinforcing rock mass in geotechnical engineering, and is characterized by that one end of the anchor cable is fixed on the reinforced rock mass, and another end of the anchor cable is anchored on the stable rock mass, and a pulling force is applied to produce compressive stress between the reinforced rock mass and the stable rock mass so as to increase anti-skid force or produce upward component force so as to reduce downward sliding force so as to attain the goal of reinforcing rock mass. However, the anchor cable is usually underground or exposed to natural environment, and is easily affected by corrosive media, such as groundwater, acid-base substances in soil, etc., so that the service life of the prestressed anchor cable is greatly reduced, and therefore, a prestressed anchor cable device is provided by those skilled in the art to solve the problems set forth in the background art. Disclosure of utility model The utility model aims to provide a pre-stressed anchor cable device which is used for solving the problems in the background technology. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a prestressed anchorage cable device, includes the anchor gasket, the surface intercommunication of anchor gasket has the spacing pipe, the surface mounting of spacing pipe has sealed the pad, the inside of spacing pipe is equipped with a plurality of steel bundles, a plurality of the surface sliding connection of steel bundles has the sealing washer jointly, the inside cover of spacing pipe is equipped with the bellows. As a still further scheme of the utility model, each steel bundle is formed by twisting a plurality of steel wires, and a grouting pipe is arranged in the corrugated pipe. As a still further proposal of the utility model, the outer surface of the anchor gasket is provided with two groups of mounting holes, and the inside of each mounting hole is provided with a mounting screw. As a still further scheme of the utility model, a plurality of anchor plates are sleeved outside the steel bundles together, and clamping pieces are clamped inside the anchor plates. As a still further proposal of the utility model, the inner wall of each clamping piece is contacted with the steel beam, and the outer surface of the anchor plate is provided with limiting holes which are annularly arranged. As a still further proposal of the utility model, a plurality of steel bundles are sleeved with pressure plates, and the outer surfaces of the pressure plates are provided with limit posts which are annularly arranged. As a still further proposal of the utility model, each limit column is matched with a limit hole, and circular holes which are annularly arranged are arranged on the outer surface of the pressure plate. As a still further scheme of the utility model, the outside of the corrugated pipe is sleeved with spiral ribs, and the sealing ring and the sealing gasket are made of rubber materials. Compared with the prior art, the utility model has the beneficial effects that: This prestressed anchorage cable device through bellows, sealing washer, sealed pad, spacing post and spacing hole's cooperation, not only can protect the steel bundle to increased the life of steel bundle by a wide margin, increased the stability of anchor plate by a wide margin moreover, thereby made the result of use of equipment better, the setting of spacing pipe, pressure plate and anchor plate can disperse the pulling force that the steel bundle received, thereby prevents that the steel bundle atress is too big and appear cracked condition.
