Description

Technical Field

[0001] The utility model relates to the technical field of bare soil covering and protection, in particular to a bare soil protection device capable of fitting and covering. Background Art

[0002] During the construction of civil engineering projects, bare soil needs to be covered to reduce the amount of particles blown into the air by the wind. This not only protects the soil from being blown away by the wind, but also protects the air from pollution.

[0003] In the bare soil on slopes or flat land, slopes or depressions where water often flows, slope protection is also needed to cover the bare soil to prevent the soil from being eroded for a long time to form potholes and holes, and to prevent landslides and loss caused by long-term erosion of the soil.

[0004] The concave bank of the river is eroded by the water flow year by year, which will cause the river bank to collapse continuously. In order to protect the safety of bridges and embankments, protective buildings must be built on the concave bank. In addition, when the river flow direction changes due to the construction of bridges, the river bank is eroded and endangers farmland and villages, protective buildings must also be built on the river bank. Generally, it is a prefabricated concrete cell, and then the grass is planted or gravel is filled inside to cover the bare soil. Then the exposed bare soil in the cell is covered and protected, so as to protect the slope surface that has been exposed to rain or water flow for a long time. Riprap, dry-laid stone, mortar-laid stone, gabions and top bundles are also used to protect the slope surface. Indirect protection is suitable for river sections with wide riverbeds or long protection lengths. Groynes, spur dams and grid dams can be built to divert the water away from the river bank.

[0005] Slope protection nets are also used on slopes or ground that are less affected by water flow. The current protection nets use relatively dense mesh to cover the slopes for protection, generally using plastic mesh or nylon mesh for full coverage protection.

[0006] This commonly used mesh for covering slopes or bare soil has dense mesh holes. With the rain or water, the mesh will be embedded in the soil layer, and the moist soil will be washed away by the rain. Some meshes will be cut off and lifted by the water, and the covering effect cannot be achieved. The holes of wire mesh are too large and the covering effect is not good. The strong metal mesh is not suitable for most environments, mainly because the mesh has poor flexibility and cannot be deformed, which results in the mesh being able to protect only very flat surfaces. It cannot be used on any slightly raised stones or uneven slopes, and can only be covered with mesh of lower strength.

[0007] Based on this, the utility model designs a bare soil protection device that can fit and cover to solve the above problems. Utility Model Content

[0008] The purpose of the utility model is to provide a bare soil protection device that can fit and cover, which can cooperate with each other through two different structures, namely a protection sheet and a positioning net. The positioning net can achieve the effect of fitting and covering various terrains, and the protection sheet can have a stronger protection effect. The higher strength positioning net can also withstand greater impact without being damaged, thus having a more comprehensive and better protection effect.

[0009] The utility model is implemented as follows: a bare soil protection device capable of fitting and covering, comprising:

[0010] Protective sheet, positioning net, ground spikes and locking rod;

[0011] The protective sheet is a fan-shaped sheet structure, and a locking hole is provided at each of the three sharp corners of the protective sheet, and each of the locking holes penetrates the front and back sides of the protective sheet;

[0012] The positioning net is a flexible mesh structure, and a plurality of ground nails are evenly installed on the positioning net. The lower end of the ground nail is a nail head, and the upper end of the ground nail is provided with an inner locking hole, and the inner locking hole is opened at the top of the ground nail;

[0013] The locking rod is a straight rod, and the locking rod can be detachably locked inside the inner locking hole;

[0014] The plurality of protective sheets are locked with the ground nails of the positioning net through locking rods.

[0015] Furthermore, the locking rod is a screw rod, the inner locking hole is a screw hole, and the locking rod is locked with the inner locking hole through a thread.

[0016] Furthermore, the positions of the locking holes on the protective sheet correspond one to one with the positions of the ground nails on the positioning net;

[0017] The hole diameter of the locking hole is larger than the diameter of the screw end of the locking rod, and the locking hole is smaller than the diameter of the nail head of the locking rod.

[0018] Furthermore, the positioning net is a planar mesh structure made of PVC or steel wire, and a ground nail is installed on the staggered nodes of each mesh on the positioning net;

[0019] A plurality of barbs are evenly arranged on the outside of the ground nail.

[0020] Furthermore, the protective sheet is a complete sheet structure made of stainless steel or PVC.

[0021] The beneficial effects of the utility model are as follows: 1. The utility model has a two-part structure of a protective sheet and a positioning net. The positioning net is responsible for positioning on the bare soil surface for fitting and covering, and generates a good anchoring force with the ground through ground nails. In addition, at the intersection of each grid, there are ground nails anchored into the ground, so that the positioning net has a better anchoring effect with the bare soil on the ground, making the positioning net fit and position more stably with the ground, and the positioning net has higher toughness, and can fit various different terrains, the covering surface fits better, and the protection effect is better;

[0022] 2. Install protective sheets on the positioning net, and the protective sheets are smaller, fan-shaped, complete sheet structures, which can cover the mesh holes on the positioning net and form a scale-like structure that covers the entire protective net in sequence, so that the protective net forms a fish-scale protective structure, which can not only effectively cover the bare soil, but also overlap the front and back, inside and outside in sequence with the erosion of the water flow, so that the protective sheets can guide the water flow from front to back, effectively reduce the impact of the water flow, reduce resistance, make the device withstand less impact force, and effectively cover the soil layer. Once a muddy soil layer is formed between the protective sheet and the soil, the protective sheet is a complete sheet, and will have a stronger adhesion to the soil layer through the muddy soil. When the water flow recedes and dries, the soil will dry up and bond the protective sheet to the soil layer more firmly. Moreover, the protective sheets are overlapped in sequence, without exposed mesh holes, and can cover the soil. The more complete package effectively reduces the erosion and loss of the soil layer.

[0030] See also Figures 1 to 4As shown, the utility model provides a bare soil protection device that can be fitted and covered. In order to better understand the above technical solution, the above technical solution will be described in detail below in combination with the drawings in the specification and specific implementation methods.

[0031] In a specific embodiment of the technical solution of the utility model:

[0032] It includes a protective sheet 1, a positioning net 2, a ground nail 21 and a locking rod 3;

[0033] The protective sheet 1 is a fan-shaped sheet structure. The protective sheet 1 is a complete sheet structure made of stainless steel or PVC. The protective sheet 1 is required to have relatively small toughness. Therefore, when the protective sheet 1 is made of stainless steel, the thickness shall not exceed 0.5mm. It is required to have toughness. PVC itself has toughness, and generally 2mm thickness is sufficient for support and protection.

[0034] A locking hole 11 is provided at each of the three sharp corners of the protective sheet 1, and each locking hole 11 penetrates both the front and back sides of the protective sheet 1; the aperture of the locking hole 11 is larger than the diameter of the screw end of the locking rod 3, so that the locking rod can pass through the locking hole 11 to install the protective sheet 1 on the positioning net 2.

[0035] The locking hole 11 is smaller than the diameter of the nail head of the locking rod 3, so as to prevent the protective sheet 1 from falling outwards, and the protective sheet 1 can be locked outside the inner locking hole 22, which is convenient to use and install.

[0036] The positioning net 2 is a flexible mesh structure. The positioning net 2 is a flat mesh structure made of PVC or steel wire. The mesh size of the positioning net 2 is related to the bare soil area and its uneven surface. Multiple different models can be designed. When the bare soil surface has small uneven points, a positioning net 2 with a smaller mesh is required. The deformation range is flexible, and even small protrusions can be deformed and fit. When the slope surface has a small uneven range and a high flatness, a positioning net 2 with a larger mesh can be selected. Generally, the mesh is rhombus-shaped, and the side length selection range is between 10cm-50cm. Different mesh sizes are selected according to different construction environments.

[0037] A ground nail 21 is installed on the staggered nodes of each mesh on the positioning net 2; the staggered nodes of the positioning net 2 have a ring-shaped through hole, which is an integral structure formed by the interweaving of the positioning net 2. This through hole is used to insert the ground nail 21. When the product leaves the factory, the ground nail 21 can be pre-installed on the through hole of the positioning net 2, or it can be removed for later installation. The tip of the ground nail 21 is inserted into the ground for anchoring, and the positioning net 2 and the ground nail 21 are locked by a locking rod 3.

[0038] The ground spikes 21 are evenly arranged with multiple barbs on the outside. The ground spikes 21 on the positioning net 2 are evenly distributed, which facilitates the locking of the protective sheet 1 on the positioning net 2. Because the protective sheet 1 has a fixed shape, a protective sheet 1 of one size can be installed and used with a positioning net 2 of a suitable size.

[0039] The lower end of the ground nail 21 is a nail head, and the upper end of the ground nail 21 is provided with an inner locking hole 22, and the inner locking hole 22 is open at the top of the ground nail 21;

[0040] The positions of the locking holes 11 on the protective sheet 1 correspond to the positions of the ground pins 21 on the positioning net 2;

[0041] The locking rod 3 is a straight rod, and the locking rod 3 can be detachably locked inside the inner locking hole 22; the locking rod 3 is a screw rod, and the inner locking hole 22 is a screw hole, and the locking rod 3 is locked with the inner locking hole 22 through a thread.

[0042] Each protective sheet 1 is locked with the ground nail 21 of the positioning net 2 through the locking rod 3, and the protective sheet 1 is installed on the positioning net 2 to form a fish scale structure.

[0043] It should be noted that:

[0044] 1. The utility model uses ground nails to anchor into the ground, so that the positioning net and the bare soil on the ground have a better anchoring effect. The commonly used covering mesh only uses external ground nails around or at specific points, which is easy to slip. Even sharp ground nails are one of the reasons for tearing the mesh. In order to fit tightly, the mesh is generally thin and flexible, and there is no design of anchor points. During on-site construction, ground nails are inserted according to the soil position for protection, and the anchoring effect is not good. The combination of the ground nails and the mesh is not strong enough. The ground nails 21 and the positioning net 2 of the present device are installed and locked as an integral structure. In order to facilitate on-site construction, they can be pre-installed as a whole when manufactured at the factory. The actual structure is that each staggered node on the positioning net 2 has a through hole, and a ground nail 21 is inserted in the through hole. The ground nail 21 itself has barbs. After the ground nail 21 is anchored in the ground, a locking rod 3 is installed on the top to clamp the positioning net 2 on the ground. It is suitable for multiple positioning nets 2 to cover each other up and down and overlap each other, and the structure has stronger integrity and is more solid.

[0045] 2. The grid holes of the positioning net 2 of the device are relatively large, and the larger the holes of the grid lines, the larger the deformation range that can be produced, so that the deformation ability of the entire positioning net 2 is stronger, so that the positioning net 2 of the device can be deformed more conveniently and flexibly, so that the positioning net 2 can be easily deformed to fit various different terrains, the covering surface is more fitted, and the protection effect is better;

[0046] 3. The device installs a protective sheet 1 on the positioning net 3, and the protective sheet 1 is a small fan-shaped complete sheet structure. The protective sheet 1 can just cover the mesh of the positioning net 3, such as Figure 3 As shown, when multiple pieces are stacked in sequence, the entire bare soil range can be covered into a scaly structure, and can be covered according to needs, that is, the positioning net 3 of the device can be cut at will according to needs, and the protective sheet 1 can be installed at will for protection according to needs, and can be suitable for bare soils of different shapes;

[0047] 4. This device needs to be installed in a stacked manner according to the direction of the water flow, that is, the protective sheet 1 in the upstream direction of the water flow needs to be on the outermost layer, and the protective sheet 1 in the downstream direction needs to be installed on the positioning net 3 and installed in the innermost layer. Figure 2 As shown, the leftmost protective sheet 1 is at the outermost layer, so the leftmost protective sheet 1 needs to face the water flow direction, and the left protective sheet 1 needs to be at the upstream, so that the water flow will only impact the first outermost protective sheet 1, and the downstream protective sheet 1 will guide the water flow and will basically not be impacted, and the first protective sheet 1 can be directly anchored and locked on the fixed concrete structure by bolts or expansion bolts, which is more secure;

[0048] On the slope, the water flow is mainly rainwater, which flows downward from the top of the slope. Therefore, the outermost protective sheet 1 needs to be set at the top of the slope, and the top protective sheet 1 can also be directly fixed on the concrete or fixed structure with the positioning net 2. When the protective sheets 1 cover the lower part of the slope in sequence, the lower protective sheets 1 need to be overlapped on the inner side of the upper protective sheet 1 to divert the water flow, effectively reduce the impact force, and reduce the chance of soil being washed away. However, in the commonly used mesh cloth nowadays, each grid will be impacted by the water flow, that is, after the upstream grid is impacted, the downstream grid will be impacted by the same force, and the soil in the mesh of the grid will be washed away with the larger water flow, that is, this kind of grid can only prevent the floating soil from being blown up or the stone from being intercepted, and it is difficult to protect against the impact of water flow.

[0049] 5. As the device is used continuously, the protective sheet 1 is a whole fan-shaped sheet. After the device is installed, when the soil layer is subjected to water flow and becomes moist, the water flow cannot directly impact the soil layer, but can only impact the protective sheet 1. The water flow will soak the soil layer along the gaps between the protective sheets 1, and the moist soil will form mud. The muddy soil will fit tightly with the protective sheet 1, thus naturally forming an overall adhesion structure. When the muddy soil is dry, the device has no grid, and the water flow will not impact and wash the soil away from the grid cloth, while the cavity formed by the bottom of the protective sheet 1 and the grid will contain mud. After the soil dries up, the protective sheet 1 will be more firmly bonded to the soil layer, forming a solid shell adhered to the surface of the bare soil.

[0050] When the utility model is in use, the upstream and downstream relationship is determined according to the difference in water flow and wind direction, and then the bare soil area to be covered is measured, and the positioning net 2 is laid. The positioning net 2 can be cut and spliced ​​according to needs. When paving the positioning net 2, it is necessary to ensure that the position of the ground nails 21 thereon can just install a protective sheet 1, and adaptive adjustment can be made according to the actual situation of the bare soil.

[0051] Moreover, the positioning net 2 of the device can also be overlapped up and down and inserted through the ground nails 21, and inserted tightly on the ground for positioning, so that the positioning net 2 can be formed relatively regular. Some surface environments are relatively irregular and need temporary cutting and supplementing or splicing.

[0052] The multiple layers of positioning nets 2 are overlapped with each other, and then the protective sheet 1 can be installed normally thereon. The ground nails 21 can also be nailed into the positioning nets 2 later. The intersection nodes between the mesh holes of the positioning nets 2 are through holes for fixing the ground nails 21. One ground nail 21 can pass through the positioning nets 2 overlapped with each other, and then the locking rod 3 is locked into the outermost part to lock and position all the positioning nets 2 and the protective sheet 1.

[0053] Ensure that the ground nail 21 is inserted under the ground. The depth of the ground nail 21 can be selected between 5-20 cm, which is determined according to the soil conditions of the bare soil. The outer wall of the ground nail 21 is provided with anti-detachment barbs, and the anchoring effect is good.

[0054] Then install the protective sheet 1 on the positioning net 2, and ensure that the protective sheet 1 of the upstream positioning net 2 is at the top, and the front end of the protective sheet 1 in the downstream direction covers the inner side of the front protective sheet 1, so as to facilitate the diversion of the water flow. According to the different shapes of the slope, the device can be laid into an uneven structure to form a scaly coating structure that fits the soil layer completely. Because the positioning net 2 can be deformed, and the protective sheet 1 can also be slightly deformed, and the protective sheet 1 is a small piece, when there is a large area of ​​uneven surface, the protective sheet 1 of the device can form a small area of ​​flat surface to follow and fit.

[0055] In general, the protective sheet 1 does not need to be deformed, and the bare soil itself can be flattened. However, this device can be directly deformed and fitted only when there are many undulating concave and convex surfaces. It is easy to install, fits tightly, has good protection effect, and has strong covering ability.

[0056] The front and back of this device refer to the front and back directions of upstream and downstream, the inside refers to the side that is in contact with the soil layer, and the outside refers to the outside of the covering soil layer; the orientation or position relationship indicated by this device is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0057] Although the specific implementation methods of the present invention are described above, those skilled in the art should understand that the specific embodiments described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
