Description

Technical Field

[0001] The utility model belongs to the field of slope anchor cable support, and particularly relates to an anti-corrosion device for anchor cables at the junction of slope lattice beams and slope surfaces. Background Technique

[0002] In slope engineering, anchor cables and lattice beams are often used for support. After the lattice beams are built, there will be gaps at the interface between the lattice beams and the slope. During long-term use, water vapor in the air will enter the anchor cable drilling holes along the gaps between the interfaces. Over time, the water vapor will gradually corrode the anchor cables, reducing the service life of the anchor cables and posing certain potential safety hazards. Therefore, how to further optimize the anti-corrosion measures for anchor cables to solve the problem that anchor cables are easily corroded during long-term use has become an urgent task at the current stage. Content of the Utility Model

[0003] The purpose of the utility model is to provide an anti-corrosion device for anchor cables at the junction of slope lattice beams and slope surfaces to solve the problem that the anchor cables at the interface between the slope lattice beams and the slope are easily corroded.

[0004] The technical solution of the utility model is: an anti-corrosion device for anchor cables at the junction of slope lattice beams and slope surfaces. The anchor cables are connected in the drilling holes of the slope lattice beams and the slope surfaces. Anchor cable clamp plates are respectively arranged in the drilling holes of the slope lattice beams and the slope surfaces. Anchor cable holes are formed on the anchor cable clamp plates. A hot melt port is arranged on one side of the anchor cable hole. The opposite surfaces of the two anchor cable clamp plates are provided with hot melt ports, and the hot melt ports are located at the anchor cable holes. The anchor cables penetrate through the anchor cable holes and the hot melt ports and are fixed on the anchor cable clamp plates. A heat shrinkable tube is arranged on the periphery of the anchor cables, and both ends of the heat shrinkable tube are connected to the hot melt ports of the two anchor cable clamp plates.

[0005] As a further improvement of the utility model, at least two clamping claws are arranged at the anchor cable holes, and a pre-tightening head is connected to the outside of the two clamping claws by threads; the anchor cables penetrate through the pre-tightening heads.

[0006] As a further improvement of the utility model, a plurality of anchor cable holes are arranged on the anchor cable clamp plates.

[0007] As a further improvement of the utility model, the anchor cable clamp plate in the drilling hole is located at a distance of 0.5 - 1.0 m from the slope surface.

[0008] As a further improvement of the utility model, the anchor cable clamp plate at the slope lattice beam is located at the middle position of the width of the slope lattice beam.

[0009] The beneficial effects of the present utility model are as follows: The present utility model adopts a structure combining an anchor cable clamp plate and a heat shrinkable tube, effectively isolating the contact between the anchor cable at the interface of the slope and the lattice beam from water vapor, and solving the engineering problem that the anchor cable at this place is prone to corrosion. Compared with the existing epoxy resin anti-corrosion measures, the heat shrinkable tube is not easily aged during long-term use, and the two ends of the heat shrinkable tube are connected to the hot melt joints of the anchor cable clamp plate, completely blocking water vapor. Such a design has better anti-corrosion durability for the anchor cable and is more suitable for long-term anti-corrosion protection. The structure of the present utility model is simple and easy to implement, and has good practicability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] As Figures 1-6As shown in the figure, an anti-corrosion device for the anchor cable at the junction of the slope lattice beam and the slope surface. The anchor cable 101 is connected in the borehole 100 of the slope lattice beam 102 and the slope surface. Anchor cable fixture plates 201 are respectively arranged in the borehole 100 of the slope lattice beam 102 and the slope surface. An anchor cable hole 205 is formed on the anchor cable fixture plate 201. A hot melt port 204 is arranged on one side of the anchor cable hole 205. The opposite surfaces of the two anchor cable fixture plates 201 are provided with hot melt ports 204. The hot melt port 204 is located at the anchor cable hole 205. The anchor cable 101 passes through the anchor cable hole 205 and the hot melt port 204 and is fixed on the anchor cable fixture plate 201. A heat shrinkable tube 203 is arranged on the periphery of the anchor cable 101. The two ends of the heat shrinkable tube 203 are connected to the hot melt ports 204 of the two anchor cable fixture plates 201.

[0019] At least two clamping jaws 206 are arranged at the anchor cable hole 205. The clamping jaws 206 and the hot melt port 204 are respectively located on both sides of the anchor cable fixture plate 201. The outer side surface of the clamping jaws 206 at the anchor cable hole 205 is conical after being enclosed. A pre-tightening head 202 is connected to the outside of the two clamping jaws 206 by threads. The inner side surface of the pre-tightening head 202 is also conical; the anchor cable 101 passes through the pre-tightening head 202. After the pre-tightening head 202 is tightened, the clamping jaws 206 are tightened inward to clamp the anchor cable 101.

[0020] Multiple anchor cable holes 205 are arranged on the anchor cable fixture plate 201.

[0021] The anchor cable fixture plate 201 in the borehole 100 is located 0.5 - 1.0 m away from the slope surface.

[0022] The anchor cable fixture plate 201 at the slope lattice beam 102 is located at the middle position of the width of the slope lattice beam 102.

[0023] The construction process is as follows:

[0024] A. Insert the anchor cable 101 into the anchor cable holes 205 of the two anchor cable fixture plates 201. After the anchor cable 101 is driven into the slope, place one anchor cable fixture plate 201 into the borehole 100 at a depth of 0.5 - 1.0 m, and tighten the pre-tightening head 202 on the clamping jaws 206 of this anchor cable fixture plate 201 so that this anchor cable fixture plate 201 is fixed on the anchor cable 101;

[0025] B. After the anchor cable fixture plate 201 in the borehole 100 is fixed, put one end of the heat shrinkable tube 203 on the heat shrinkable head 204 of the anchor cable fixture plate 201;

[0026] C. Place the other anchor cable fixture plate 201 into the slope lattice beam 102 so that it is located at the middle position of the width of the slope lattice beam 102, and tighten the pre-tightening head 202 on the clamping jaws 206 of this anchor cable fixture plate 201 so that this anchor cable fixture plate 201 is fixed on the anchor cable 101;

[0027] D. Slip the other end of the heat-shrinkable tube 203 onto the heat-shrink head 204 of the cable anchor fixture plate 201 at the slope lattice beam 102.

[0028] E. Heat the heat-shrinkable tube 203 with a hot air blower so that the heat-shrinkable tube 203 tightly adheres to the cable anchor 101 and the heat-shrink heads 204 at both ends for fixation.

[0029] F. Place a steel plate 104 outside the slope lattice beam 102 and pre-tension the cable anchor 101.

[0030] G. Fix the cable anchor 101 through the anchor head 105 and pour concrete 106 at the position of the anchor head 105 for sealing the anchor.

[0031] The heat-shrinkable tube 203 cooperates with the cable anchor fixture plate 201 to isolate the cable anchor 101 from the outside world, preventing the cable anchor 101 at the interface between the slope lattice beam 102 and the slope from being corroded by water vapor, extending the service life of the cable anchor, and eliminating potential safety hazards.
