Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy engineering auxiliary equipment, in particular to a water conservancy slope protection net. Background Art

[0002] Water conservancy slope protection usually includes planting plants on the slope, building protective buildings, etc., to reduce the scouring effect on the slope and improve the safety of the shore. At present, there are direct protection and indirect protection for slope protection. Among them, direct protection is more commonly used. Direct protection mainly involves laying stone slabs and protective nets directly on the shore to resist the scouring and scouring of water.

[0003] The protective net is the most commonly used due to its easy operation. The current slope protection net is mainly fixed on the slope. When the water flows, it can prevent the water from directly scouring the soil, and it can intercept the soil on the slope to reduce soil loss. The structure of the slope protection net varies, mainly single-layer or multi-layer nets. When used, the slope protection net fits the convex surface more closely, so the water will still directly act on the soil through the mesh when scouring, resulting in soil loss, which is not conducive to long-term protection of the soil. Summary of the invention

[0004] In view of this, the utility model provides a hydraulic slope protection net, specifically a hydraulic slope protection net provided with a support, a first net layer group and a second net layer group. The slope protection net has the advantages of reasonable design, strong practicality and convenient use. The slope protection net can effectively reduce soil loss and achieve long-term protection of the slope soil layer.

[0005] On the basis of the prior art, the utility model provides a water conservancy slope protection net, comprising a first net layer group and a second net layer group; a plurality of support members are installed between the first net layer group and the second net layer group, and the support members are arc-shaped;

[0006] When the slope protection net is installed on the slope, the supports are distributed from the high point to the low point of the slope;

[0007] The first mesh layer group is connected to the bottom end of the support member; the second mesh layer group is connected to the top, the middle of the side and the bottom of the side of the support member;

[0008] After connection, the first mesh layer group is close to the soil surface of the slope, and the second mesh layer group is above the first mesh layer group and partially arc-shaped under the action of the support member; when water flows toward the slope, part of the water flows downward along the bottom end of the arc-shaped support member, and part of the water flows through the support member and the second mesh layer group into the interior of the support member, and flows from high to low along the area of ​​the support member. Since the water flow entering the interior of the support member is blocked by the second mesh layer group and the support member, its flow speed is reduced. Therefore, the impact force of this part of the water flow on the slope soil layer is significantly reduced, thereby reducing the loss of soil layer caused by water flow scouring, thereby facilitating the long-term protection of the slope.

[0009] Preferably, the first mesh layer group includes at least one layer of interception net A, and the second mesh layer group includes at least one layer of interception net A; the setting of multiple layers of interception net A can slow down the scouring of water flow, thereby avoiding the problem of slope damage caused by excessive soil layers carried by high-speed water flow.

[0010] Preferably, in order to ensure that the support member can stably support the second mesh layer group, one end of the support member is fixed on the connecting rod A, and the other end is fixed on the connecting rod B, and the connecting rod A and the connecting rod B are connected by the connecting rod C; the inner top of the support member is fixed on the connecting rod D; this arrangement enables the support member to maintain a stable shape, which is conducive to resisting the scouring force of water flow and improving the reliability and stability of the slope protection net when in use.

[0011] Preferably, the support member is formed by bending a rod or a plate.

[0012] Preferably, when the support member is a plate-bending structure, a through hole is provided on the support member to further reduce the speed at which water flows into the interior of the support member and reduce scouring of the slope soil layer.

[0013] Preferably, an interception net B is installed on the support member, and the interception net B covers the arc-shaped area of ​​the support member; this arrangement can further slow down the water flow, intercept the soil layer, and minimize soil loss.

[0014] Compared with the prior art, the beneficial effect of the utility model is that, by setting the first mesh layer group and the second mesh layer group, the scouring force of the water flow can be reduced under the interception of the second mesh layer group, thereby reducing the loss of soil layers as much as possible and achieving the purpose of protecting the slope; by setting the support member, the second mesh layer group can be supported, so that the second mesh layer group presents a flat convex circulation structure, and when the water flow impacts, the water flow can be diverted, that is, on the one hand, the water flow can be redirected under the cooperation of the support member and the second mesh layer group so that the water flow flows downward near the contact position between the second mesh layer group and the bottom of the support member, and on the other hand, it can enter the interior of the support member at a lower speed to reduce the scouring force, thereby achieving the purpose of protecting the slope soil surface. The above-mentioned settings make the slope protection net have the advantages of reasonable design, strong practicality and easy use. The use of the slope protection net can effectively reduce the loss of soil layers and achieve long-term protection of the slope soil layer. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The support member 2 is a rod bending forming structure;

[0027] When the slope protection net is installed on the slope, the support members 2 are distributed from the high point to the low point of the slope;

[0028] In order to ensure that the support member 2 can stably support the second mesh layer group, one end of the support member 2 is fixed on the connecting rod A3, and the other end is fixed on the connecting rod B4. The connecting rod A3 and the connecting rod B4 are connected by the connecting rod C5. In this embodiment, the connecting rod C5 corresponds to the two ends of the support member 2; the inner top of the support member 2 is fixed on the connecting rod D6; this setting enables the support member 2 to maintain a stable shape, which is conducive to resisting the scouring force of water flow and improving the reliability and stability of the slope protection net when it is used;

[0029] The first mesh layer group is connected to the bottom end of the support member 2;

[0030] The second mesh layer group is connected to the top, the middle and the bottom of the side of the support member 2;

[0031] When the first mesh layer group and the second mesh layer group are connected to the support member 2, they can be connected by using a binding belt 9 or the like, which is convenient for connection and is convenient for replacement after the first mesh layer group and / or the second mesh layer group is damaged;

[0032] In addition to the connection between the first mesh layer group and the second mesh layer group and the support member 2, the first mesh layer group and the second mesh layer group are also directly connected by a binding band 9;

[0033] In addition, according to the requirements of the slope size, more support members 2 can be connected and used to improve the flexibility of the slope protection net, and improve the practicality and applicability of the slope protection net;

[0034] An interception net B7 is installed on the support 2, and the interception net B7 covers the arc-shaped area of ​​the support 2; this setting can further reduce the speed of the water flow, intercept the soil layer, and minimize the loss of the soil layer;
