Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of slope protection, especially to the geotechnical engineering slope protection net connecting structure. BACKGROUND

[0002] The geotechnical engineering slope refers to the slope surface with certain inclination angle formed in the rock-soil body due to the change of topography and geomorphology, which is the product of natural or artificial reformation of terrain, such as natural mountain slope in mountainous area, artificial slope formed by road construction, etc. The slope is mainly composed of rock-soil body, and its stability is influenced by many factors, such as rock-soil property (such as rock type, soil particle size, etc.), underground water condition, slope structure (such as whether there is fault, fissure, etc.), and external load (such as earthquake force, vehicle load, etc.). The geotechnical engineering slope is an important object of geotechnical engineering research, and the stability analysis, protection design and treatment of the slope are the key links to ensure the safety of engineering and prevent geological disasters such as landslide. The protection net is a facility specially used for the protection of geotechnical engineering slope, which is usually woven by high-strength metal wire or synthetic fiber, etc. It has certain flexibility and strength, can adapt to irregular terrain of the slope, intercept and block the falling soil and rock, etc. on the slope, effectively reduce the force borne by a single point by dispersing the impact force to a larger area, so as to protect the buildings, roads, personnel, etc. under the slope from the damage of collapse, rockfall, etc. The protection net can be divided into active protection net and passive protection net. The active protection net can actively cover and reinforce the slope surface, and inhibit the weathering and peeling, collapse, etc. of the rock-soil body on the slope surface. The passive protection net is mainly set at a specific position under the slope to block the rolling objects.

[0003] The geotechnical engineering slope protection net connecting structure is a structure for tightly connecting the components of the protection net (such as support rope, anchor rod, pressure relief ring, steel column, etc.), mainly including rope clamp, bolt, stitched rope, etc. connecting elements, which ensures that the protection net forms a stable whole, and transmits the rockfall impact or rock-soil body pressure received by the protection net to the anchor rod and stable slope rock-soil body through the connecting structure. For example, when the rockfall hits the protection net, the impact force is conducted through the connected support rope, so that the anchor rod bears the tension and disperses the force to the surrounding rock-soil body. At the same time, the connecting structure can also work with the components of the protection net, such as the pressure relief ring connected to the support rope through the connecting structure, which deforms to absorb energy when subjected to large impact force, so as to ensure the effective protection of the slope safety by the protection net under complex working conditions.

[0033] The outside middle part of rolling ball 6 is equipped with rubber elastic ring 7, which plays a role of buffering and damping, when the connecting structure is impacted by external force, rubber elastic ring 7 can absorb part of energy through elastic deformation; on the other hand, rubber elastic ring 7 increases the friction force when rolling ball 6 contacts with the outside, which helps to limit the excessive rolling of rolling ball 6 to some extent, so that the connecting structure is more stable, and the outside of another support rope 3, i.e. the left side of buffer net 1 is equipped with multiple connecting blocks two 8, and connecting block two 8 is also used for the connection of support rope 3, the inside of connecting block two 8 is equipped with sleeve mouth two 9, so that support rope 3 can be inserted smoothly therein;

[0036] With reference to Figures 2 to 4 The inner wall of the sleeve setting opening one 5 and the right side of the buffer net 1, that is, the outer part of the supporting rope 3, are in contact, when the supporting rope 3 is inserted into the sleeve setting opening one 5 from the right side of the buffer net 1, the close contact enables the pulling force of the supporting rope 3 to be effectively transmitted to the connecting block one 4, the inner wall of the sleeve setting opening two 9 and the left side of the buffer net 1, that is, the outer part of the other supporting rope 3, are in contact, after the supporting rope 3 is inserted into the sleeve setting opening two 9, the constraint on the supporting rope 3 is further enhanced, preventing it from loosening due to factors such as vibration and stretching during long-term use, and the outer part of the rolling ball 6 is slidingly connected in the inside of the connecting groove 13, ensuring that the rolling ball 6 freely rolls therein, and also limiting its movement within a certain range to prevent it from coming off the connecting groove 13.

[0037] The outer left side of the rubber elastic ring 7 and the left side of the inner wall of the connecting groove 13 are in contact, displacement or angle change of the supporting rope 3 caused by rockfall impact enables the rolling ball 6 to flexibly roll in the connecting groove 13, effectively relieving stress concentration caused by deformation of the supporting rope 3, and at the same time, elastic deformation of the rubber elastic ring 7 also cooperates to absorb part of the energy, protecting the connecting structure from damage, the two rotating grooves 15 are formed in the inside of the anchor rod 14, ensuring that the reinforcing assembly can be reinforced in opposite directions, the proximal sides of the two springs 19 are fixedly connected to the inner walls of the two rotating grooves 15, when the land extrudes the extrusion plate 17, the extrusion plate 17 drives the rotating column 16 to rotate, and when the reinforcing block 18 expands outward against the elastic force of the spring 19, the spring 19 stores elastic potential energy, and once the pulling force decreases or disappears, the spring 19 releases the elastic potential energy to pull the reinforcing block 18 back to the initial position, ensuring that the whole reinforcing assembly can be restored to the original state in time.

[0038] The inner wall of the fixing hole 12 is threadedly connected with a screw 20. During installation, the screw 20 is screwed into the fixing hole 12, and the sliding block 11 is firmly fixed at a specific position in the sliding groove 10 of the connecting block two 8 through the biting effect of the thread. The outer top of the plurality of support ropes 3 is sleeved with a pressure relief ring 21, which is an important energy absorption device in the protective net connecting structure. The outer part of the extrusion plate 17, i.e. the top of the rotating column 16, is rotationally connected in the inner part of the rotating groove 15, so that the extrusion plate 17 can be extruded in the vertical direction by the soil, thereby driving the rotating column 16 to rotate in the rotating groove 15. The outer part of the reinforcing block 18, i.e. the bottom of the rotating column 16, is rotationally connected in the inner part of the rotating groove 15, which ensures that the reinforcing block 18 can rotate in the anchor rod 14 along with the rotation of the rotating column 16, thereby inserting into the soil and reinforcing the protective net. The support rope 3 supports the buffer net 1 when the buffer net 1 is placed on the slope, and the support rope 3 supports the entire buffer net 1 like a skeleton. The sliding block 11 connects a plurality of buffer nets 1 after the screw 20 is fixed in the fixing hole 12, and after the screw 20 is tightened in the fixing hole 12, it tightly connects adjacent buffer nets 1.

[0039] Working principle: when using, the protective net needs to be assembled, the sliding block 11 is pushed to slide in the connecting block two 8, the rolling ball 6 is placed in the connecting groove 13, and after placement, the screw 20 is fixed in the connecting block two 8 through the fixing hole 12 to limit the rolling ball 6, thereby connecting the connecting block one 4 and the connecting block two 8, and connecting adjacent buffer nets 1. When there is a rockfall impact, the impact force is transmitted to the support rope 3 through the buffer net 1, the support rope 3 slides in the connecting groove 13 through the rolling ball 6, while the rubber elastic ring 7 buffers and dampens the rolling ball 6 and limits the rolling, and the pressure relief ring 21 at the top of the support rope 3 absorbs energy by deforming itself, thereby protecting the entire protective net connecting structure and the slope.

[0040] When the protective net needs to be reinforced, the anchor rod 14 is first inserted into the soil, the soil exerts an extrusion force on the extrusion plate 17, driving the rotating column 16 to rotate in the rotating groove 15, thereby causing the reinforcing block 18 to overcome the spring 19 elastic force and expand outward and insert into the soil for anchoring. When the anchor rod 14 leaves the soil, the spring 19 automatically resets the reinforcing block 18 by its elastic action.

[0041] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
