[0037] The present invention discloses a highway reconstruction excavation slope reinforcement structure, which is applied to highway slope reinforcement to shorten the construction period of slope reinforcement and improve construction efficiency. The overall structure, working principle and technical effects of the highway reconstruction excavation slope reinforcement structure provided by the present invention are described in detail below through embodiments and in conjunction with the accompanying drawings.

[0038] Please refer to Figure 1The highway reconstruction excavation slope reinforcement structure includes a prefabricated top plate 100, a prefabricated bottom plate 200 and a prefabricated frame 300. The prefabricated top plate 100 is a rectangular plate body. The prefabricated top plate 100 is arranged at the top of the slope parallel to the length direction of the highway. The prefabricated top plate 100 is fixed to the top of the slope by a fixed anchor rod 110. The prefabricated bottom plate 200 is also a rectangular plate body. The prefabricated bottom plate 200 is arranged at the bottom of the slope parallel to the length direction of the highway. The prefabricated bottom plate 200 is fixed to the bottom of the slope by a fixed anchor rod 110. The prefabricated frame 300 is a rectangular frame body. Several prefabricated frames 300 are arranged and fitted on the slope, and the prefabricated frames 300 are all located between the prefabricated top plate 100 and the prefabricated bottom plate 200. In order to fix the prefabricated frame 300 to the slope, a plurality of reinforcement anchor rods 310 are also arranged on the side of the prefabricated frame 300 facing the slope. Furthermore, in order to improve the stability of the installation of the prefabricated frame 300, a number of reinforcement rods 400 are detachably connected between the prefabricated top plate 100 and the prefabricated bottom plate 200. The reinforcement rods 400 are arranged perpendicular to the length direction of the highway, and the reinforcement rods 400 are located at the contact point of two adjacent prefabricated frames 300. The reinforcement rods 400 are connected to both adjacent prefabricated frames 300.

[0039] The prefabricated top plate 100, the prefabricated bottom plate 200 and the prefabricated frame 300 are all prefabricated in the prefabrication yard and then transported to the construction site. The prefabricated frame 300 is fixedly installed on the slope through the reinforcement anchor rod 310 by setting the reinforcement anchor rod 310 on the prefabricated frame 300, and the reinforcement rod 400 between the prefabricated top plate 100 and the prefabricated bottom plate 200 is used to reinforce the prefabricated frame 300, so that the prefabricated frame 300 is firmly installed on the slope. By installing the prefabricated frame 300 on the slope to reinforce the slope, there is no need to pour the grid concrete on the slope on site, which shortens the construction period and improves the construction efficiency.

[0040] Furthermore, when part of the prefabricated frame 300 is damaged, the reinforcing rod 400 can be disassembled, and after the damaged prefabricated frame 300 is removed, a new prefabricated frame 300 is replaced, and then fixed with the reinforcing rod 400. This makes it easy to maintain and replace the prefabricated frame 300, and improves the problem that the current grid concrete is not easy to maintain.

[0041] It is understood that in this embodiment, the prefabricated top plate 100 and the prefabricated bottom plate 200 are fixed to the slope by fixing anchor rods 110. In other embodiments, the prefabricated top plate 100 and the prefabricated bottom plate 200 can also be fixed by structures such as embedded piles. The reinforcement rod 400 can be connected to the prefabricated top plate 100 and the prefabricated bottom plate 200 by bolts, welding, etc.

[0042] Please refer to Figure 2 and Figure 3In order to improve the effect of the reinforcing rod 400 in fixing the prefabricated frame 300, step surfaces 320 are provided on both sides of the prefabricated frame 300. When several prefabricated frames 300 are arranged and installed on the slope, the step surfaces 320 of two adjacent prefabricated frames 300 jointly form a receiving groove, and the reinforcing rod 400 is located in the receiving groove. Through the cooperation between the reinforcing rod 400 and the receiving groove, the prefabricated frame 300 is positioned, and the fixing effect of the reinforcing rod 400 on the prefabricated frame 300 is improved.

[0043] During the highway reconstruction process, the newly excavated slope soil structure is loose, which leads to a large amount of erosion and loss of slope soil in rainy weather. At the same time, the weak soil water storage capacity makes it difficult for the vegetation planted on the slope to survive, resulting in poor slope protection and reinforcement effects. At the same time, in order to ensure the survival of the vegetation planted on the slope, it is necessary to water the vegetation planted on the slope through water trucks and other equipment in the early stage of planting, which increases the operation and maintenance costs.

[0044] Please refer to Figure 2 and Figure 3 In some optional embodiments, water collecting chambers 330 are provided on both sides of the prefabricated frame 300 and in the bottom frame, and filter holes 331 communicating with the water collecting chamber 330 are provided on the inner side of the prefabricated frame 300. At the same time, the reinforcement anchor rod 310 on the prefabricated frame 300 is hollow, the reinforcement anchor rod 310 is communicated with the inner cavity of the water collecting chamber 330, a plurality of water outlet holes 311 are provided on the reinforcement anchor rod 310, and the water collecting chamber 330 and the hollow reinforcement anchor rod 310 are filled with water retaining materials. The water retaining materials are materials with good water absorbing and retaining properties, such as water-absorbing sponges, highly absorbent polymers, and cotton and linen fibers.

[0045] By setting the water collection chamber 330 in the prefabricated frame 300, rainwater can enter the water collection chamber 330 through the filter hole 331 for storage in rainy weather, reducing the flow of rainwater on the slope, thereby reducing soil erosion and loss. At the same time, in dry weather, the soil is dry. At this time, under the action of the osmotic pressure inside and outside the reinforcement anchor rod 310, the water in the water-retaining material in the water collection chamber 330 is input into the soil, thereby continuously providing moisture for the vegetation on the slope to improve the survival rate of the vegetation.

[0046] Please refer to Figure 3 and Figure 4Furthermore, in order to further enhance the diversion and water collection effect of the water collection chamber 330, in some optional embodiments, a water collection tank 120 is provided on the prefabricated top plate 100, and a filter 130 is provided on the prefabricated top plate 100 and located on the opening side of the water collection tank 120 to prevent other debris from entering the water collection tank 120. A water delivery chamber 410 connected to the water collection tank 120 is provided in the reinforcement rod 400. In addition, a plurality of connectors 500 are provided on the reinforcement rod 400, and the plurality of connectors 500 correspond to the plurality of prefabricated frames 300 one by one, and the connectors 500 are used to connect the water delivery chamber 410 with the water collection chamber 330. By setting a water collection trough 120 on the prefabricated top plate 100 and setting a water transfer cavity 410 in the reinforcement rod 400, the collection and diversion effect of rainwater is further improved, thereby reducing the amount of water overflow on the slope during rainy weather to reduce soil loss; at the same time, the rainwater collected on the prefabricated top plate 100 is diverted to multiple prefabricated frames 300 for storage, thereby improving the rainwater collection efficiency.

[0047] Please refer to Figure 3 The connecting member 500 includes a threaded sleeve 510 and a driving unit. A first threaded hole 420 communicating with the water delivery chamber 410 is provided on the side of the reinforcing rod 400 facing the prefabricated frame 300. A second threaded hole 340 is provided on the side of the prefabricated frame 300 facing the reinforcing rod 400. The first threaded hole 420 is opposite to the second threaded hole 340, and the two have the same size. The threaded sleeve 510 is a pipe body with threads processed on the outer wall. The threaded sleeve 510 is threadedly connected to the reinforcing rod 400 and is located at the first threaded hole 420. The driving unit is arranged on the reinforcing rod 400 and connected to the threaded sleeve 510. The driving unit is used to drive the threaded sleeve 510 to rotate so that the threaded sleeve 510 moves between the first threaded hole 420 and the second threaded hole 340. Therefore, when the threaded sleeve 510 is threadedly matched with the first threaded hole 420 and the second threaded hole 340 at the same time, the water delivery chamber 410 is connected with the water collecting chamber 330. The driving part includes a connecting rod 520 and a gripping end 530. The diameter of the connecting rod 520 is smaller than the inner diameter of the threaded sleeve 510. The connecting rod 520 is coaxially connected to the threaded sleeve 510 through a support rod. The connecting rod 520 extends away from the prefabricated frame 300 and is threaded through the reinforcement rod 400. The gripping end 530 is provided at one end of the connecting rod 520 located outside the reinforcement rod 400. The gripping end 530 is used for the operator to hold, thereby facilitating the operator to drive the threaded sleeve 510 to rotate.

[0048] When the reinforcement rod 400 is installed in place and the first threaded hole 420 on the reinforcement rod 400 is aligned with the second threaded hole 340 on the prefabricated frame 300, the operator holds the gripping end 530 tightly and drives the threaded sleeve 510 to rotate, and rotates the threaded sleeve 510 to cooperate with the first threaded hole 420 and the second threaded hole 340 at the same time, so as to facilitate the connection between the water transfer chamber 410 and the water collection chamber 330. At the same time, it can also connect the fixing rod to the prefabricated frame 300, thereby improving the fixing effect of the reinforcement rod 400 on the prefabricated frame 300.

[0049] It is understandable that a water-retaining material is also filled in the threaded sleeve 510. When the threaded sleeve 510 is rotated to be matched with the first threaded hole 420 and the second threaded hole 340 at the same time, the water-retaining material in the threaded sleeve 510 connects the water-collecting cavity 330 with the water-retaining material in the water-transferring cavity 410. Thus, water flows in the water-retaining material in the water-collecting cavity 330 and the water-transferring cavity 410 under osmotic pressure or capillary action. If the water-retaining material is a water-absorbing sponge or fiber material, when the reinforcing rod 400 is installed on the prefabricated frame 300, the threaded sleeve 510 is first filled with the water-retaining material.

[0050] Please refer to Figure 5 Furthermore, in some optional embodiments, a water storage chamber 210 is provided in the prefabricated base plate 200, and the water storage chamber 210 is connected to the water delivery chamber 410. In addition, a water-retaining material is also provided in the water delivery chamber 410. By providing the water storage chamber 210 in the prefabricated base plate 200, the water storage capacity of the overall reinforcement structure is improved. At the same time, when the soil is dry, the water in the water storage chamber 210 is transported to the soil through the reinforcement anchor rod 310 to irrigate the vegetation through the osmotic pressure between the water delivery chamber 410 and the water-retaining material in the water collection chamber 330. Thereby, the amount of water flowing over the slope is effectively reduced in rainy weather, the scouring and loss of slope soil is reduced, and the stored water is used to irrigate the vegetation in dry weather, saving water resources and improving the survival rate of vegetation.

[0051] Please refer to Figure 1 and Figure 5 Furthermore, a plurality of joints 220 connected to the water storage chamber 210 are arranged at intervals on the prefabricated bottom plate 200. By arranging a plurality of joints 220 on the prefabricated bottom plate 200, when the rainfall is heavy, the joints 220 can be opened to discharge the water in the water storage chamber 210 directly into the ditch for discharge, thereby improving the drainage effect of the slope; and when the weather is dry, the joints 220 can also be used to connect external water supply facilities, such as municipal water supply systems, natural water sources, etc., to supply water to the water storage chamber 210, and the water in the water storage chamber 210 is then transported to the slope soil through the water transfer chamber 410 and the water-retaining materials in the water collection chamber 330 to irrigate the vegetation. There is no need to set up additional irrigation devices, nor is there any need to irrigate along the road using water trucks and other equipment, thereby reducing costs.

[0052] In summary, the implementation principle of the highway reconstruction excavation slope reinforcement structure provided by the present invention is: the prefabricated top plate 100, the prefabricated bottom plate 200 and the prefabricated frame 300 are all prefabricated in the prefabrication yard and then transported to the construction site, and the prefabricated frame 300 is fixedly installed on the slope through the reinforcement anchor rod 310 by setting the reinforcement anchor rod 310 on the prefabricated frame 300, and the reinforcement rod 400 between the prefabricated top plate 100 and the prefabricated bottom plate 200 is used to reinforce the prefabricated frames 300, so that the prefabricated frames 300 are firmly installed on the slope. By installing the prefabricated frame 300 on the slope to reinforce the slope, there is no need to pour the grid concrete on the slope on site, which shortens the construction period and improves the construction efficiency.

[0053] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
