Description

Technical Field

[0001] The invention relates to the technical field of slope protection, and in particular to a slope safety protection device for reservoir construction. Background Art

[0002] In the construction of reservoirs, slope safety protection is an important part of ensuring the safety of construction workers and the smooth progress of the project. Due to the complex and changeable geological conditions, natural erosion and the impact of construction activities, the slope structure of the reservoir is often unstable, and there is a risk of loose gravel rolling down, which not only threatens the lives of on-site workers, but also may cause damage to mechanical equipment and affect the progress of the entire project.

[0003] At present, in order to stabilize the slope and protect the personnel and equipment in the construction area, the commonly used methods include pouring concrete slope protection structures and installing slope protection nets. The former strengthens the slope by building a solid concrete structure to prevent it from sliding or collapsing; however, this method is expensive and is not suitable for terrain with extremely steep slopes. In contrast, the latter, which covers the slope with flexible slope protection nets, is more cost-effective and more suitable for slope protection at various angles. These slope protection nets can effectively intercept small gravel that may slide down and reduce direct danger.

[0004] Nevertheless, as the construction period continues, some small gravels may gradually fall through the gaps in the slope protection net and accumulate on the net. If these accumulations are not dealt with in time, they will also cause new safety hazards and lead to greater accident risks. It is necessary to regularly clean up the gravel or lay a secondary protection net again, either way, it is time-consuming and labor-intensive. Summary of the invention

[0005] The purpose of the present invention is to provide a slope safety protection device for reservoir construction, which adopts a protection net to intercept gravel falling from the slope, and also has an adaptive cleaning function to prevent large-scale accumulation of gravel and reduce the cost of later maintenance.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a slope safety protection device for reservoir construction, wherein the protection device is arranged in multiple levels along the slope from top to bottom, each protection device includes a slope protection net, and multiple fixed plug shafts are arranged side by side at the bottom of the slope protection net, and one end of each fixed plug shaft is connected to an upward inclined support rod, except that the two inclined support rods at the end are fixedly connected to the corresponding fixed plug shaft, and each inclined support rod is horizontally rotatably connected to the corresponding fixed plug shaft, two support nets are connected between every two inclined support rods, one side of every two support nets is connected to the corresponding inclined support rod, and the free edges of the two support nets between every two inclined support rods overlap with each other and are not connected, and a support steel rope is connected between the two ends of each adjacent two inclined support rods, and the corresponding two ends of each support net are connected to the corresponding support steel rope.

[0007] By adopting the above technical solution, when gravel falls through the slope protection net, it will be intercepted by the support net below and gradually accumulated on the support net. When the gravel on the support net gradually accumulates, the weight generated pulls the support steel rope to produce elastic deformation, and the surrounding support steel ropes gradually deform to cause the inclined support rods to rotate inward. After reaching a certain degree, the opening between the two support nets opens, allowing the gravel on it to fall down to the next level of support net. If the next level of support net cannot bear it, it will automatically open the opening to drop the gravel to the next level, and release the gravel step by step until the gravel slowly falls to the ground at the bottom. After the gravel is released, the support net is reset under the elastic recovery of itself and the support steel rope, thereby restoring the gravel interception capability.

[0008] The present invention is further configured as follows: the free end of each fixed plug shaft is provided with a U-shaped connecting seat with openings on the left and right sides, the lower end of each inclined support rod is vertically provided with a connecting head corresponding to the corresponding U-shaped connecting seat, each U-shaped connecting seat is penetrated from top to bottom with a mounting hole, and each connecting head is penetrated from top to bottom with a rotating hole matching the mounting hole, each U-shaped connecting seat and the corresponding connecting head are connected by a rotating shaft penetrating the corresponding mounting hole and the corresponding rotating hole, both ends of each rotating shaft extend out of the corresponding mounting holes and are provided with threaded sections, each threaded section is threadedly connected with a connecting nut, the cross-section of the connecting heads on the two inclined support rods at the end is a rectangle matching the corresponding U-shaped connecting seat, and the cross-section of the connecting heads on the remaining inclined support rods is a U-shape rotatably connected to the corresponding U-shaped connecting seat.

[0009] The present invention is further configured as follows: a plurality of J-shaped hooks are arranged on the left and right sides of each inclined support rod and are distributed along the length direction thereof and are detachably connected to the corresponding support net.

[0010] The present invention is further configured as follows: both sides of each supporting net are connected to corresponding supporting steel ropes via connecting steel wires.

[0011] The present invention is further configured as follows: the aperture of the support net is smaller than the aperture of the slope protection net.

[0012] In summary, the present invention has the following beneficial effects: the safety protection of the present invention is used for slope gravel protection, with simple construction and low cost. During long-term use, the gravel falls onto the supporting net and accumulates. After reaching a certain level, the gap between the two supporting nets opens, and the gravel is buffered and released step by step downward. After multi-stage buffering and release from top to bottom, the impact force of the falling gravel is effectively eliminated, so that it will not threaten the safety of surrounding construction workers. At the same time, after the gravel is self-cleaned, the gravel interception function can be restored, and no manual cleaning or reinforcement is required, which can effectively reduce subsequent maintenance costs.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] Example, see Figure 1-4 A slope safety protection device for reservoir construction, the protection device is arranged in multiple levels from top to bottom along the slope, and a gravel collection ditch for accumulating gravel is excavated along the slope below the lowest level. Each protection device includes multiple slope protection nets 1, each slope protection net 1 is mainly used to stabilize larger stones so that they cannot fall. Multiple fixed plug shafts 2 are arranged side by side under the slope protection net 1. When installing, holes are drilled on the slope, the fixed plug shafts 2 are inserted, and then filled with concrete. One end of each fixed plug shaft 2 is connected to an upwardly inclined inclined support rod 3, and the free end of each fixed plug shaft 2 is provided with a U-shaped connecting seat 21 with openings on both sides. The lower end of each inclined support rod 3 is vertically provided with a connecting head 31 corresponding to the corresponding U-shaped connecting seat 21, and each U-shaped connecting seat 21 is penetrated from top to bottom to open a mounting hole 22, and each connecting head 31 is penetrated from top to bottom to open a rotating hole 32 that matches the mounting hole 22, and each U-shaped connecting seat 21 and the corresponding connecting head 31 are connected by a rotating shaft that penetrates the corresponding mounting hole 22 and the corresponding rotating hole 32. 4 connection, both ends of each rotating shaft 4 extend out of the corresponding mounting hole 22 to be provided with a threaded section 41, each threaded section 41 is threadedly connected with a connecting nut 42, the cross-section of the connecting heads 31 located on the two inclined support rods 3 at the end is a rectangle matched with the corresponding U-shaped connecting seat 21, so that the inclined support rods 3 at both ends cannot rotate relative to the fixed plug-in shaft 2, and the cross-section of the connecting heads 31 on the remaining inclined support rods 3 is a U-shape rotatably connected with the corresponding U-shaped connecting seat 21, so that the inclined support rods 3 at both ends cannot rotate relative to the fixed plug-in shaft 2, while the middle inclined support rod 3 can rotate left and right relative to the fixed plug-in shaft 2.

[0023] Two supporting nets 5 are connected between every two inclined support rods 3, and the aperture of the supporting nets 5 is smaller than the aperture of the slope protection net 1. One side of every two supporting nets 5 is connected to the corresponding inclined support rods 3. The left and right sides of each inclined support rod 3 are provided with a plurality of J-shaped hooks 33 distributed along its length direction and detachably connected to the corresponding supporting nets 5, which are convenient for connecting the supporting nets 5 with the inclined support rods 3. The free edges of the two supporting nets 5 between every two inclined support rods 3 overlap with each other and are not connected, so that the two supporting nets 5 can be opened downward. A supporting steel rope 6 is connected between the two ends of every two adjacent inclined support rods 3, and the corresponding two ends of each supporting net 5 are connected to the corresponding supporting steel rope 6. The two sides of each supporting net 5 are connected to the corresponding supporting steel rope 6 through connecting steel wires 7, and the connecting steel wires 7 are passed through the mesh of the supporting net 5 and then connected to the supporting steel rope 6.

[0024] Working principle: when gravel falls through the slope protection net 1, it will be intercepted by the support net 5 below and gradually accumulate on the support net 5. When the gravel on the support net 5 gradually accumulates, the weight generated pulls the support steel rope 6 to produce elastic deformation, and the surrounding support steel rope 6 gradually deforms to make the inclined support rod 3 rotate inward. After reaching a certain degree, the opening between the two support nets 5 opens, allowing the gravel on it to fall down to the next level of support net 5. If the next level of support net 5 cannot bear it, it will automatically open the opening to drop the gravel to the next level, and release the gravel step by step until the gravel slowly falls to the ground at the bottom. After the gravel is released, the support net 5 is reset under the elastic recovery of itself and the support steel rope 6, and the gravel interception ability is restored.
