Problems solved by technology
[0004] In order to overcome the deficiencies in the prior art, the present invention proposes an intelligent early warning anchor cable device for side (slip) slopes, which solves the problem that most of the existing anchor cable and slope anchor cable devices do not have the function of intelligent early warning when in use, and cannot accurately warn the anchor cable. Real-time detection of the tensile force that the cable can bear, the protection and safety performance is low, and during the installation process of the anchor chain, most of the sliding connection with the anchor cable device, the pre-tightening process is time-consuming and laborious, and the installation is more inconvenient.

Embodiment Construction
[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0026] like Figure 1-Figure 5 As shown, a side (slip) slope intelligent early warning anchor cable device includes a prefabricated concrete layer 1, a pre-buried head 2, a pressure sensor 4, an anchor chain fixing column 1 7, a bearing 9, an anchor chain fixing column 2 2, etc., and the precast concrete A pre-buried head 2 is pre-embedded inside layer 1, and a detection flange 3 is arranged above the pre-buried head 2. The detection flange 3 is connected with the pre-buried head 2 with a ball joint, and the detection flange 3 is fixedly connected to the anchor chain fixing column-7, and the anchor...

The invention discloses a side slope (landslide) intelligent early warning anchor cable device and method. An embedded head is embedded in a precast concrete layer, a detection flange is arranged above the embedded head, and the detection flange is in spherical hinge connection with the embedded head; a pressure sensor is arranged between the detection flange and the precast concrete layer, the detection flange is fixedly connected with anchor chain fixing columns, and a plurality of limiting flanges are arranged at the lower parts of the anchor chain fixing columns; and bearings are installedbetween the limiting flanges, and through holes for penetrating the anchor chain are formed in the upper parts of the anchor chain fixing columns. According to the invention, by arranging the pressure sensor and the intelligent early warning device, the tension borne by the anchor cable device can be detected in real time; by arranging the bearings between the limiting flanges, the original sliding friction force can be converted into rolling friction force when the anchor chain is bound, so that the anchor chain can be tensioned and fixed conveniently and quickly, and the operation is convenient.
Description
technical field [0001] The invention relates to the technical field of anchor cable devices, in particular to an intelligent early warning anchor cable device for side (slip) slopes. Background technique [0002] Prestressed anchor cable protection is to use a certain strength of cement mortar to form an anchor body with a certain strength at the bottom of the anchor hole at an effective depth and the surrounding rocks, and then under the prestressing effect of the anchor cable, the unstable mountain part is firmly connected to the surrounding rock. Stabilize the mountain as a whole, ensure the stability of the slope, and prevent the further development of structural cracks, so as to achieve the purpose of protection. On the one hand, the prestressed anchor cable can directly generate anti-sliding resistance on the sliding surface; The normal stress of the slope is used to increase the anti-sliding frictional resistance, thereby improving the integrity and stability of the s...
