Description

Technical Field

[0001] The invention relates to the field of slope protection, in particular to a high-fill and deep-dig type substation engineering slope ecological protection device. Background Art

[0002] In recent years, the infrastructure construction of substation projects in mountainous areas has been rapidly developed. In order to achieve the connectivity of circuits in mountainous areas, it is inevitable to penetrate narrow valley areas during site selection, planning and design. As a result, there are many projects combining excavation and filling with steep roadbed slopes. At the same time, in order to protect the original ecological system, the requirements for slope design for excavation or backfilling slopes are constantly increasing, almost harsh, thus forming a large number of slopes. If these slopes are not protected, landslides are likely to cause road ruptures.

[0003] In order to prevent soil erosion and scouring erosion, drainage measures and slope protection measures are generally adopted. Traditional slope protection structures generally adopt concrete pouring and vegetation planting. The use of concrete pouring is not only very expensive, but also not environmentally friendly. In remote areas, the transportation of large amounts of concrete is also very inconvenient. Simple vegetation maintenance is seriously affected by vegetation growth. Slope protection systems with poor vegetation growth will suffer from severe soil erosion, which can easily cause slope sliding and dislocation, thus affecting the normal use of the road.

[0004] Based on the above reasons, research on new slope protection systems has received increasing attention. For example, patent document CN202220618196.0 discloses a highway engineering slope protection lattice structure and a highway engineering slope protection structure. However, some parts of the structure still require cement mortar for connection, and still face the problems of inconvenient construction and inconvenient material transportation. Summary of the invention

[0005] The purpose of the present invention is to provide a high-fill deep-dig type substation engineering slope ecological protection device to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned invention object, the present invention adopts the following technical scheme:

[0007] A slope ecological protection device for a high-fill and deep-excavation substation project comprises a positioning frame and a protective mesh panel group, wherein the protective mesh panel group comprises a protective mesh panel monomer, the positioning frame comprises a transverse positioning rod, the protective mesh panel monomer is inserted into the positioning rod, the left and right adjacent protective mesh panel monomers are snap-connected, and the upper and lower adjacent protective mesh panel monomers are abutted against each other.

[0008] Furthermore, matching card slots and card strips are respectively provided on both sides of the protective mesh plate monomer, and the protective mesh plate monomers adjacent to the side are detachably connected by inserting the card strips into the card slots.

[0009] Preferably, the clamping groove is a dovetail groove, and the clamping strip is a dovetail strip. The dovetail groove extends longitudinally along the protective mesh plate monomer, and adjacent protective mesh plate monomers are transversely locked by plugging the dovetail groove and the dovetail strip.

[0010] Furthermore, the positioning frame includes two parallel fixing bars, the positioning rod is detachably arranged between the two fixing bars, and a transverse mounting hole is provided on the protective mesh plate unit, and the protective mesh plate unit is inserted into the positioning rod through the mounting hole.

[0011] As a preference, the upper end face of the protective mesh plate monomer is parallel to its own lower end face, and both end faces are gradually inclined upward from front to back, and in two upper and lower adjacent protective mesh plate monomers, the lower end face of the upper protective mesh plate monomer overlaps the upper end face of the lower protective mesh plate monomer.

[0012] Furthermore, the mounting hole is located at the upper end of the protective mesh plate unit, and the protective mesh plate unit can be flipped around the positioning rod.

[0013] As another preferred embodiment, the upper end face of the protective mesh plate monomer is parallel to its own lower end face, and both end faces are gradually inclined downward from front to back. Among the two adjacent protective mesh plate monomers above and below, the upper end face of the protective mesh plate monomer located below is in contact with the lower end face of the protective mesh plate monomer located above, thereby locking the downward movement tendency of the protective mesh plate monomer located above.

[0014] Furthermore, the protective mesh plate monomer is provided with a through hole which is inclined upward from the front to the back.

[0015] Furthermore, a reflective layer is provided on the inner wall of the through hole of the protective mesh plate unit, and the reflective layer is used to guide light into the deep of the through hole.

[0016] Furthermore, the positioning frame also includes an anchor rod, and the fixing bar is provided with an anchor hole. The anchor rod passes through the anchor hole to fix the positioning frame on the slope.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The main structure of the present invention only includes a positioning frame and a protective mesh plate group, and has a simple structure. It is not only easy to produce, but also has a low production cost and can be produced in large quantities.

[0019] 2. The protective mesh panel monomer only needs to be inserted into the positioning rod, and the adjacent protective mesh panel monomers on the left and right can be connected by snap-fitting to quickly assemble into a large protective mesh panel group. A large number of protective monomers can be assembled through this simple splicing, which greatly reduces the difficulty of construction, is easy to implement and saves construction time.

[0020] 3. The protective mesh has a simple monomer structure and can be made of metal, polymer or composite materials. According to different soil types, climates, environments, etc., suitable materials can be selected to enhance service life, save costs, or reduce construction intensity.

[0021] 4. The protective mesh panel group is composed of protective mesh panel monomers that can be detachably spliced, and through holes are set on the protective mesh panel monomers, which have the advantages of small size and light weight. When the entire device is transported, the largest number of protective mesh panel monomers are protective mesh panel monomers, and the protective mesh panel monomers are mesh panel structures, which are not only light in weight, but also do not take up space and are easy to transport. For remote areas and areas with poor road conditions, this lightweight and compact structure greatly reduces the difficulty of transportation and construction intensity.

[0030] See also Figure 1-7 This embodiment discloses a slope ecological protection device for a high-fill deep-dig type substation engineering project, the structure of which includes a positioning frame 100 and a protection mesh plate group 200 assembled on the positioning frame 100 and parallel to the slope.

[0031] The positioning frame 100 includes two parallel fixing bars 110, the fixing bars 110 are arranged vertically, and a positioning rod 140 is detachably arranged between the two fixing bars 110, and the positioning rod 140 is arranged horizontally. The protective mesh panel group 200 is formed by detachably splicing the protective mesh panel monomers 210, and the protective mesh panel monomers 210 are provided with horizontal mounting holes 240, and the protective mesh panel monomers 210 are inserted on the positioning rods 140 through the mounting holes 240. The distance between two adjacent positioning rods 140 is the length of the protective mesh panel monomers 210. The positioning frame 100 also includes anchor rods 130, and the upper and lower ends of the fixing bars 110 are provided with anchor holes 120 that penetrate the fixing bars 110, and the anchor rods 130 pass through the anchor holes 120 and extend into the slope, thereby fixing the positioning frame 100 on the slope.

[0032] The protective mesh plate monomer 210 is evenly provided with through holes 250, which make the protective mesh plate monomer 210 a mesh plate structure, light in weight, thereby reducing the construction strength. Preferably, the through holes 250 are arranged upwardly from front to back. When used, when rainwater hits the protective mesh plate monomer 210, since the through holes 250 are arranged upwardly, the rainwater cannot directly hit the slope, and the through holes 250 will slow down the impact of the rainwater and guide the rainwater downward to the bottom of the slope, avoiding the rainwater directly hitting the slope and causing water and soil loss on the slope, thereby avoiding causing the slope to slide and move.

[0033] In a specific structure, matching card slots 220 and card strips 230 are respectively provided on both sides of the protection mesh plate monomer 210, and the protection mesh plate monomers 210 adjacent to the side are detachably connected by inserting the card strips 230 into the card slots 220. Figure 4 and Figure 6 Two types of card slot 220 structures are shown respectively and will not be described in detail.

[0034] Preferably, the slot 220 is a dovetail slot, the strip 230 is a dovetail strip, the dovetail slot extends longitudinally along the protective mesh plate monomer 210, and adjacent protective mesh plate monomers 210 are transversely locked by plugging the dovetail slot and the dovetail strip. In this way, after the slot 220 and the strip 230 are combined, the adjacent protective mesh plate monomers 210 are locked in transverse movement, and when the protective mesh plate monomers 210 are inserted on the positioning rod 140, they are longitudinally locked, and the assembly is convenient and firm without the need for other tools or adhesive materials.

[0035] The protective mesh plate monomer 210 can be made of metal materials, polymer materials or composite materials, etc., and the range of materials is wide. In addition, the use of such a prefabricated structure is convenient for speeding up construction on site and shortening the construction period.

[0036] During installation, after the construction personnel splice the protective mesh plate monomers 210, align the installation holes 240 on the protective mesh plate monomers 210 with the positioning rods 140, and sequentially pass the protective mesh plate monomers 210 on the positioning rods 140, and at the same time make the clamping strips 230 of the adjacent protective mesh plate monomers 210 clamped into the clamping grooves 220, and repeat the above operations in sequence until the positioning rods 140 are fully covered with the protective mesh plate monomers 210, and then fix the positioning rods 140 to a pair of fixing strips 110. A clamping groove or clamping hole structure can be set on the fixing strips 110, and the two ends of the positioning rod 140 are clamped on the two fixing strips 110 respectively, or the positioning rod 140 and the fixing strip 110 are fixed by threaded connection.

[0037] Repeat the above operation until the space between the pair of fixing bars 110 is filled with the protective mesh plate monomers 210, and finally fix the fixing bars 110 by the anchor rods 130 to complete the installation, thereby effectively improving the construction efficiency and reducing the labor intensity.

[0038] On the basis of the above structure, based on different construction environments and whether it is necessary to plant vegetation on the slope, the present invention also provides two improved structures of the protective mesh plate monomer 210. As follows:

[0039] Embodiment 1

[0040] For slopes suitable for planting plants, such as Figure 3 and Figure 6 As shown, in this embodiment, there is a gap between the protection mesh panel set 200 and the slope, and a vegetation layer is planted at the position of the slope corresponding to the protection mesh panel set 200.

[0041] The two sides of the protective mesh plate unit 210 along the slope direction are parallel to each other and form an obtuse angle with the downward slope of the slope, that is, the upper end surface of the protective mesh plate unit 210 is parallel to its own lower end surface, and both end surfaces gradually tilt upward from front to back.

[0042] After the assembly is completed, the lower end surface of the upper protective mesh panel monomer 210 of the two adjacent protective mesh panel monomers 210 is overlapped on the upper end surface of the lower protective mesh panel monomer 210, so that the protective mesh panel group 200 is erected on the vegetation layer. In this way, the entire protective device only contacts the slope surface at the fixing strip 110, which increases the planting area compared to some existing protective devices that can only plant vegetation in the frame, and is more conducive to preventing and controlling soil erosion.

[0043] The mounting hole 240 is located at the upper end of the protective mesh panel unit 210, and the protective mesh panel unit 210 can be turned around the positioning rod 140. Each layer of the protective mesh panel unit 210 can be opened, and when a part of the vegetation dies, the vegetation can be planted and replaced. Since the through hole 250 is set on the protective mesh panel unit 210, the through hole 250 allows sunlight to pass through, so that the vegetation layer can perform normal photosynthesis. When it rains, it can prevent rainwater from directly impacting the vegetation layer, preventing the vegetation layer from being directly impacted by rainwater, resulting in soil erosion on the slope, and then causing the roots of the vegetation layer to be exposed to the outside world and causing the death of the vegetation.

[0044] In order to make the vegetation more conducive to growth, further, a reflective layer is provided on the inner wall of the through hole 250 of the protective mesh plate monomer 210, and the reflective layer is used to introduce light into the depth of the through hole 250. The inner wall is provided with a reflective layer, which can reflect sunlight onto the vegetation, further enabling the vegetation layer to perform normal photosynthesis.

[0045] Embodiment 2

[0046] Targeting certain slopes that are not suitable for growing plants or where vegetation grows poorly, such as rocky slopes and slopes in arid areas.

[0047] like Figure 4 and Figure 7 As shown, in the present embodiment, the two sides of the protective mesh plate monomer 210 along the slope direction are parallel to each other and the angle between them and the downward direction of the slope is an acute angle, that is, the upper end face of the protective mesh plate monomer 210 is parallel to its own lower end face, and both end faces are gradually inclined downward from front to back. Among the two adjacent protective mesh plate monomers 210 above and below, the upper end face of the protective mesh plate monomer 210 located below is in contact with the lower end face of the protective mesh plate monomer 210 located above, thereby locking the downward movement trend of the protective mesh plate monomer 210 located above.

[0048] In this way, after the assembly is completed, the top edge of the protective mesh plate monomer 210 along the slope direction can lock the bottom edge of the protective mesh plate monomer 210 above it, that is, the protective mesh plate monomer 210 is clamped by the slope and the upper end of the protective mesh plate monomer 210 below it, so that the protective mesh plate monomer 210 is always close to the slope, which can prevent the slope from being displaced and causing landslides.
