[0043] Example 1
[0044] In order to solve the problem that the existing technology does not fully consider that the old river channel has been affected by long-term water scouring, erosion and geological conditions, resulting in loose soil structure and reduced stability, which makes it easy for the two sides of the river channel to collapse during or after the transformation process or the problem of poor anti-seepage effect. Figure 1-5 As shown, a river channel anti-seepage structure is provided, including a reinforcement structure 1 for reinforcing both sides of the river channel, a geomembrane 2, an anti-seepage concrete layer 3 and a stone layer 4 arranged on the reinforcement structure 1 in sequence; the reinforcement structure 1 includes reinforcement columns 5 drilled into both sides of the river channel, a steel mesh 6 hung on the reinforcement column 5 and a primary concrete layer 7 sprayed on the steel mesh 6. Each component selects corresponding materials according to requirements.
[0045] In practice, the silt in the old river channel is first cleaned, and then excavation is carried out. Then, the reinforcing columns 5 in the reinforcement structure are drilled into both sides of the river channel, and the steel mesh 6 is hung in turn, and the initial layer of concrete 7 is sprayed for reinforcement. After reinforcement, the geomembrane 2 is laid on the reinforcement structure, the anti-seepage concrete layer 3 and the dry-hanging or wet-hanging stone layer 7 are poured. When renovating old river channels, this embodiment drills the reinforcing columns in the reinforcement structure into both sides of the river channel, and hangs a steel mesh and sprays an initial layer of concrete thereon to improve the overall structural strength of the river channel and achieve a preliminary anti-seepage effect. It can effectively resist the scouring and erosion of water flow and reduce damage to river embankments, thereby improving the flood control capacity of the river channel. That is, it fully considers that the old river channel has been affected by long-term scouring, erosion and geological conditions of water flow, resulting in loose soil structure and reduced stability. The reinforcement structure is used for reinforcement to avoid the problem of river channel collapse or poor anti-seepage effect that is easy to find during or after the renovation process. At the same time, the use of this river channel anti-seepage structure does not require much space, which is conducive to the renovation of old river channels with limited space.
[0046] Example 2
[0047] On the basis of Example 1, the reinforcing column 5 includes a conical column 8, and an elastic hanging piece 9 obliquely arranged on the conical column 8, the inclination angle of the elastic hanging piece 9 is set according to practical needs, such as 10°-20°, and a fixing part 10 that cooperates with the conical column 8 to fix the steel mesh 6; the elastic hanging piece 9 is located at the cone tip end of the conical column as the lower end.
[0048] In practice, the conical column 8 is drilled into the designated position on both sides of the river channel, and the elastic hanging piece 9 is squeezed into the soil. After drilling, due to the reset effect of the elastic hanging piece 9, it is tightly in contact with the soil to avoid the problem of loose fixation of the conical column 8 after drilling. After the conical column 8 is drilled into the soil, a steel mesh is hung on the opposite side of its cone tip and fixed by a fixing piece. Therefore, in this embodiment, the reinforcement column is easily drilled into the soil through the conical column and is tightly combined with the soil, thereby enhancing the stability and bearing capacity of the entire reinforcement structure. The purpose of setting the elastic hanging piece is to facilitate the conical column to be drilled into the soil, and to use its own reset effect to stabilize the conical column, so that the steel mesh can be effectively hung later.
[0049] Example 3
[0050] On the basis of Example 2, a slot 11 is provided on the conical column 8 on the opposite side of the cone tip of the conical column 8, and a plurality of limit blocks A12 are provided on the inner wall of the slot 11 at equal intervals along the circumference direction of the inner wall of the slot 11; the fixing member 10 includes an insertion column 13 matched with the slot 11, and the insertion column 13 is provided with a limit block B14 matched with the limit block A12 to fix the fixing member 10 on the conical column 8, and a fixing structure 15 provided on one end of the insertion column 13 to fix the steel mesh 6.
[0051] In practice, after the steel mesh is hung on the conical column 8, the limit block B14 on the plug column 13 is matched with the limit block A12, so that the limit block A12 limits the fixing member from being separated from the conical column 8. After being fixed, the steel mesh 6 can be fixed on the river channel through the fixing structure 15 on the plug column 13. In this embodiment, a slot is provided on the opposite side of the cone tip of the conical column, and a plurality of limit blocks A are provided at equal intervals on the inner wall of the slot along the circumference direction of the conical column, so that the limit block B can be quickly matched with the limit block A for fixing after the fixing member is inserted into the slot, and the fixing structure on the fixing member can be used to quickly fix the steel mesh on the river channel.
[0052] Example 4
[0053] On the basis of Embodiment 3, a plurality of limit blocks A12 are provided on the inner wall of the slot 11 along the depth direction of the slot 11. Figure 4 , 5 As shown, each group of limit blocks A set along the conical column 8 is two, and of course it can also be set to three, etc., and each group of limit blocks A set along the depth direction of the slot 11 is two, and of course it can also be set to three, etc. It is convenient to make the limit blocks A on the fixing member match with different limit blocks A in the length direction of the slot according to the thickness of different steel meshes or river channel structures, so as to facilitate the steel mesh to be tightly fixed on the river channel. If the exposed part of the conical column 8 is too long after being inserted into the soil, if you want to fix the steel mesh, you need to make the limit block B14 match with the limit block A located on one side of the bottom of the slot 11.
[0054] Example 5
[0055] On the basis of Example 4, Figure 4 As shown, the limit block A12 is provided with a clamping groove 16 with one side open and matched with the limit block B14; or as Figure 5 As shown, along the depth direction of the slot 11, a clamping cavity 17 for accommodating the limit block B14 is formed between each limit block A12 and between the limit block A12 and the bottom of the slot 11; the limit block B14 is slidably matched with the channel formed between two adjacent limit blocks A12 along the circumference direction of the slot 11. When the limit block B14 and the clamping groove 16 or the clamping cavity 17 are located in the same horizontal plane, the fixing member 10 can rotate along the circumference direction of the slot 11.
[0056] In practice, the limit block A12 corresponds to the channel and slides along the channel to the position of the clamping groove 16 or the clamping cavity 17, and when the limit block B14 and the clamping groove 16 or the clamping cavity 17 are located in the same horizontal plane, the fixed part can be rotated to transfer the limit block B14 into the clamping groove 16 and / or the clamping cavity 17. Since one side of the clamping groove 16 is open, the limit block B is transferred into the open side, and the other side plays a role of rotation limitation to achieve positioning rotation, which can effectively avoid the problem of transferring to the clamping groove 16. Therefore, in this embodiment, the limit block B is fixed by setting a clamping groove with an open side on the limit block A, which is convenient for limited rotation and is conducive to the fixation of the fixed part; the limit block B is fixed by forming a clamping cavity for accommodating the limit block B between the two limit blocks A and between the limit block A and the bottom of the slot, which has a simple structure and can also be quickly fixed. Of course, in practice, it is not ruled out that the limit block A can also be fixed by other structures. When the initial concrete layer is poured, the concrete will be poured onto the tapered columns and fixings, and after solidification, the purpose of forming an overall effect is achieved.
[0057] Example 6
[0058] On the basis of Example 5, the fixing structure 15 includes a fixing plate 18 and a fixing rod 19 arranged on the fixing plate 18, so as to facilitate fixing the steel bars thereunder by combining the fixing plate and the fixing rod. The fixing plate 18 is a circular structure or a square structure, and of course, it can also be other structures. The fixing rod 19 is a telescopic rod, the purpose of which is to facilitate rotating the fixing structure after the fixing rod is retracted to avoid it being affected by the uneven river surface, and the extension is to increase the pressing area for pressing the steel mesh onto the river.
