Slope lattice expansion joint reinforcement structure

Abstract

The invention discloses a reinforcing structure for an expansion joint in a side slope lattice, which comprises cuboid reinforcing bodies and an anchor rod passing through the expansion joint in parallel, both sidewalls of the expansion joint are concave along the longitudinal direction of lattice beams, so that grooves for fastening the reinforcing bodies are formed, and the reinforcing bodies are fixedly connected with the anchor rod. Because the reinforcing bodies are fixed by the anchor rod and expansion gaps are arranged, when the lattice beams deform in different directions under the action of a variety of factors (temperature change, creep deformation, earthquake and the like), external force is transferred onto the anchored anchor rod by the reinforcing bodies, and then acts on steadier rock in in a slope body, consequently, while the function of the expansion joint is ensured, the mechanical property of the lattice beams in different directions is improved, the bending moment resistance and other capability of the lattice beams are enhanced, the structural strength in side slope reinforcement is ensured, the overall strength of the lattice beams is enhanced, and the occurrence of major accidents is prevented.

Description

technical field [0001] The invention relates to the field of slope reinforcement, in particular to a reinforcement structure of a slope lattice expansion joint. Background technique [0002] Slope generally refers to a rock mass with an inclined slope surface. Due to the inclination of the slope surface, the entire slope body has a tendency to slide from high to low under the action of the slope's own gravity and other external forces. Generally, it can be reinforced by lattice Reinforce the slope surface; the lattice reinforcement technology is a slope reinforcement technology that uses mortar block stones, cast-in-place reinforced concrete or prefabricated prestressed concrete to protect the slope surface, and fixes it with anchor rods or anchor cables. , the main function of the lattice is to distribute the remaining sliding force or earth pressure and rock pressure of the slope to the anchor rods or anchor cables at the lattice joints, and then transmit them to the stabl...

[0002] Slope generally refers to a rock mass with an inclined slope surface. Due to the inclination of the slope surface, the entire slope body has a tendency to slide from high to low under the action of the slope's own gravity and other external forces. Generally, it can be reinforced by lattice Reinforce the slope surface; the lattice reinforcement technology is a slope reinforcement technology that uses mortar block stones, cast-in-place reinforced concrete or prefabricated prestressed concrete to protect the slope surface, and fixes it with anchor rods or anchor cables. , the main function of the lattice is to distribute the remaining sliding force or earth pressure and rock pressure of the slope to the anchor rods or anchor cables at the lattice joints, and then transmit them to the stable stratum through the anchor cables, so that the slope The body is in a stable state under the action of the anchoring force provided by the anchor rod or anchor cable, and in the prior art, every 10-25 meters of lattice width needs to be provided with expansion joints, which are used to adapt to the lattice beam under various factors ( Temperature change, creep deformation, load action, uneven foundation settlement and earthquake) produce deformation, and fill the expansion joint with asphalt hemp tendon or asphalt plank; and such a structure makes the bending resistance of the lattice beam at the expansion joint The moment capacity is not good and the strength is not high, which is not conducive to the lattice structure as a whole to improve the firmness of the slope surface
