Description

A small-scale watershed slope ecological restoration structure Technical Field

[0001] This utility model belongs to the field of ecological environment governance technology, and in particular relates to a small watershed bank slope ecological restoration structure. Background Technology

[0002] With the continuous development of society and the continuous improvement of people's living standards, people's requirements for the environment are also getting higher and higher, especially for some small watershed areas, which are closely related to people's lives. The management of small watersheds is also very important. When managing small watersheds, the management of their banks is also a very important measure. The management of banks usually involves planting some vegetation on the banks. This can prevent the banks from collapsing and also create a certain natural landscape effect.

[0003] Existing technology includes an ecological restoration layer located on the riverbank, with a support structure between the ecological restoration layer and the river channel. The support structure comprises multiple prefabricated blocks, each with through holes containing a filter screen. The prefabricated blocks enhance the support and protection of the ecological restoration layer on the riverbank, preventing its collapse. The through holes allow river water to seep into the ecological restoration layer, while the filter screens prevent excessive leakage of materials from the ecological restoration layer into the river channel.

[0004] However, in actual use, the materials of the ecological restoration layer and impurities in the river water can easily clog the filter screen, causing it to block the through holes on the prefabricated blocks. As a result, the river water does not seep into the ecological restoration layer effectively. Since the filter screen is directly installed in the through holes on the prefabricated blocks, cleaning it can only be done by going deep into the river or by digging up the ecological restoration layer. However, this also affects the ecological restoration layer, making the cleaning of the filter screen quite troublesome. Summary of the Invention

[0005] The purpose of this invention is to provide a small-scale watershed bank ecological restoration structure that facilitates the cleaning of clogged filter screens.

[0006] The aforementioned small-scale watershed slope ecological restoration structure includes prefabricated blocks. An ecological restoration layer is provided on the rear side of the prefabricated blocks. The prefabricated blocks have vertically arranged through holes, and filter screens are installed inside the through holes. Each filter screen is fitted with an installation frame. A first sliding groove is provided on the prefabricated blocks corresponding to the installation frame in the upper through hole for the upper installation frame to slide out from the top of the prefabricated blocks. A second sliding groove is provided on the prefabricated blocks corresponding to the installation frame in the lower through hole for the lower installation frame to slide out from the top of the prefabricated blocks. A traction component is provided on the installation frame in the lower through hole to pull it out from the second sliding groove.

[0007] Furthermore, a first fixing rod is vertically fixed to the top of the mounting frame inside the upper through hole.

[0008] Furthermore, the second groove includes a first groove, a second groove, and a third groove. The first groove is used to allow the mounting frame in the lower through hole to slide upward. The first groove is connected to the lower through hole and is separated from the upper through hole. The second groove allows the mounting frame in the first groove to slide horizontally. The third groove is located at the top of the second groove and is used to allow the mounting frame in the second groove to slide upward.

[0009] Furthermore, the traction assembly includes a connecting block horizontally fixed to the top of the side wall of the mounting frame, a second fixing rod vertically fixed to the top of the connecting block, and both the connecting block and the second fixing rod are located within the second sliding groove.

[0010] Furthermore, the top of the first fixing rod and the second fixing rod have the same diameter. The top of the second fixing rod and the top of the first fixing rod are both horizontally provided with positioning holes. A bolt is independently provided in one of the positioning holes, and a nut with threaded engagement is provided on the bolt. A fixing block is horizontally provided above the bolt and is independent of it. Two parallel clamping blocks are vertically fixed at the bottom of the fixing block. The diameter of the second fixing rod and the first fixing rod is smaller than the distance between the two clamping blocks. The clamping blocks are provided with mounting holes for the bolt screw to pass through. A handle is provided on the top of the fixing block.

[0011] Furthermore, the second slide is a slide for the mounting frame inside the lower through hole to slide upwards, and the second slide connects the upper and lower through holes.

[0012] Furthermore, the traction assembly includes a vertically arranged connecting rod that fixes the upper and lower mounting frames.

[0013] Furthermore, a third sliding groove is provided on the top of the rear side of the through hole of the prefabricated block, and a baffle is independently provided in the third sliding groove. When the baffle is located in the third sliding groove, the baffle is used to separate the filter and the ecological restoration layer.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This utility model allows the mounting frame to be removed from the through hole on the prefabricated block through the second and first sliding grooves on the prefabricated block, thereby removing the filter screen inside the mounting frame from the through hole on the prefabricated block. This facilitates cleaning of the filter screen, and the cleaned filter screen can be put back into the through hole on the prefabricated block, which can reduce the impact of filter screen blockage on river water seepage into the ecological restoration layer.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0022] The small-scale watershed slope ecological restoration structure described in this embodiment, as shown in Figures 1, 2, and 3, includes a prefabricated retaining block 1. The prefabricated retaining block 1 has four through holes arranged vertically, in pairs, overlapping vertically to facilitate the creation of sliding grooves. A filter screen 3 is installed inside each through hole. Several prefabricated retaining blocks 1 are provided, with adjacent blocks abutting against each other. Both the prefabricated retaining block 1 and the through holes are existing known technologies, such as the structure of the prefabricated retaining block in patent number CN202120596237.6.

[0023] The filter screen 3 is equipped with mounting frames 2 on its edges. The filter screen 3 has a rectangular structure, and the through holes on the prefabricated block 1 have a rectangular structure. The size of the filter screen 3 is the same as the size of the through holes on the prefabricated block 1. The mounting frame 2 is a rectangular frame, and the inner frame of the mounting frame 2 is the same size as the through holes on the prefabricated block 1. Mounting grooves for embedding the mounting frame 2 are provided on both sides of the through holes. The mounting grooves are connected to the through holes. In this way, when the filter screen 3 is located in the through hole, its mounting frame 2 is located in the mounting groove, which can prevent the mounting frame 2 from sliding back and forth in the through hole, thereby confining the filter screen 3 in the through hole. The filter screen 3 is installed in the mounting frame 2. The filter screen 3 can be a metal mesh, and the mounting frame 2 is a metal mesh. The mounting frame 2 and the filter screen 3 are welded together. Alternatively, the mounting frame 2 can be two rectangular frames of the same size, and the filter screen 3 can be clamped and fixed in the two rectangular frames, or the mounting frame 2 and the filter screen 3 can be fixed with bolts.

[0024] The mounting frame 2 in the upper through hole has a first sliding groove 1.2 on the prefabricated block 1 for the upper mounting frame 2 to slide out from the top of the prefabricated block 1. The first sliding groove 1.2 is connected to the upper through hole. The mounting frame 2 in the lower through hole has a second sliding groove 1.1 on the prefabricated block 1 for the lower mounting frame 2 to slide out from the top of the prefabricated block 1.

[0025] A first fixing rod 6 is vertically fixed to the top of the mounting frame 2 inside the upper through hole. The top of the first fixing rod 6 extends beyond the top of the prefabricated stop block 1. The first fixing rod 6 facilitates the upward pulling of the mounting frame 2 inside the upper through hole, thereby removing the mounting frame 2 inside the upper through hole from the first slide groove 1.2. Of course, in some embodiments, a rope can also be provided at the top of the mounting frame 2 to pull the upper mounting frame 2. Moreover, since the mounting frame 2 is made of metal, a magnet can also be used to pull the upper mounting frame 2 out of the first slide groove 1.2.

[0026] The second slide groove 1.1 includes a first groove, a second groove, and a third groove. The first groove is used to allow the mounting frame 2 in the lower through hole to slide upward. The first groove is connected to the lower through hole and is spaced from the upper through hole. The second groove allows the mounting frame 2 in the first groove to slide horizontally. When the top of the lower mounting frame 2 contacts the top of the first groove, the lower mounting frame 2 can slide horizontally in the second groove. The third groove is located at the top of the second groove and is used to allow the mounting frame 2 in the second groove to slide upward. The left second slide groove 1.1 is located to the left of the left mounting frame 2, and the right second slide groove 1.1 is located to the right of the right mounting frame 2. The second slide groove 1.1 has a first groove to prevent the lower mounting frame 2 from moving horizontally in the lower through hole, thus blocking the through hole with the filter screen 3. This paragraph as a whole constitutes the second slide groove 1.1 used to allow the lower mounting frame 2 to slide out from the top of the prefabricated stop block 1.

[0027] A connecting block 4 is horizontally fixed to the top of the side wall of the mounting frame 2, and a second fixing rod 5 is vertically fixed to the top of the connecting block 4. Both the connecting block 4 and the second fixing rod 5 are located within the second sliding groove 1.1. The left connecting block 4 is fixed to the top of the left side wall of the lower left side of the mounting frame 2, and the right connecting block 4 is fixed to the top of the right side wall of the mounting frame 2. Both the second fixing rod 5 and the connecting block 4 can slide horizontally within the second sliding groove 1.1. The width of the third groove is not less than the width of the mounting frame 2 plus the length of the connecting block 4, allowing both the connecting block 4 and the mounting frame 2 to slide vertically within the second sliding groove 1.1. The second fixing rod 5 is fixed to the side wall of the mounting frame 2 via the connecting block 4, and the mounting frame 2 can be pulled using the second fixing rod 5. This entire section constitutes a traction assembly for pulling the mounting frame 2 out of the lower through hole from the second sliding groove 1.1.

[0028] In use, as shown in Figure 1, to pull the lower left mounting frame 2 out of the second sliding groove 1.1 on the left, pull the lower left mounting frame 2 upward using the second fixing rod 5 on the left. When the lower left mounting frame 2 contacts the top of the first groove on the left, pull the second fixing rod 5 to the left, causing the lower left mounting frame 2 to move to the left within the second groove on the left. When the lower left mounting frame 2 contacts the left side of the second groove on the left, the right side of the lower left mounting frame 2 is completely below the third groove, preventing... The prefabricated stop 1 obstructs the pulling out of the mounting frame 2, and then the second fixing rod 5 on the left is pulled upward, so that the mounting frame 2 on the lower left slides upward in the third groove on the left, so that the mounting frame 2 on the lower left is taken out from the top of the prefabricated stop 1. When the mounting frame 2 on the lower left is placed into the through hole below, the same method is used: first, the mounting frame 2 is put into the third groove, and then the mounting frame 2 slides in the second groove, enters the first groove, and is then located in the through hole below. The method of pulling out the mounting frame 2 on the lower right is the same as the method on the left.

[0029] The second slide groove 1.1 is a slide groove for the mounting frame 2 to slide upward within the lower through hole. The second slide groove 1.1 connects the upper and lower through holes, as shown in Figure 4. That is, the second slide groove 1.1 connects the upper and lower through holes, and the second slide groove 1.1 is located directly below the first slide groove 1.2. This paragraph as a whole constitutes another structure of the second slide groove 1.1 for allowing the lower mounting frame 2 to slide out from the top of the prefabricated stop block 1.

[0030] The upper and lower mounting frames 2 are fixed by vertically arranged connecting rods 12. The first fixing rod 6 is vertically fixed to the top of the upper mounting frame 2. In use, as shown in Figure 4, when the upper mounting frame 2 is pulled upward by the second fixing rod 5, the lower mounting frame 2 can be pulled by the connecting rod 12, thereby pulling both the upper and lower mounting frames 2 out together into the prefabricated stop block 1. The upper and lower mounting frames 2 are fixed by the connecting rod 12 to prevent the upper mounting frame 2 from falling downward, thus ensuring that the upper filter screen 3 is located in the upper through hole. This paragraph as a whole constitutes another structure of the traction assembly that pulls the mounting frame 2 in the lower through hole out of the second slide groove 1.1.

[0031] The top of the first fixing rod 6 has the same diameter as the second fixing rod 5. Both the top of the second fixing rod 5 and the top of the first fixing rod 6 have horizontally oriented positioning holes. A bolt 7 is independently installed in one of the positioning holes, and a nut with a threaded connection is installed on the bolt 7. A fixing block 9, independent of the bolt 7, is horizontally positioned above it. Two parallel clamping blocks 10 are vertically fixed to the bottom of the fixing block 9. The diameters of the second fixing rod 5 and the first fixing rod 6 are smaller than the distance between the two clamping blocks 10. The clamping blocks 10 have mounting holes for the bolt 7 to pass through. A handle 8 is provided on the top of the fixing block 9. The clamping blocks 10 can be connected to the second fixing rod 5 or the first fixing rod 6 using the bolt 7 and nut. A fixing rod 6 is used to connect the second fixing rod 5 and the first fixing rod 6, which is convenient. The clamping block 10, the fixing block 9 and the second fixing rod 5 or the first fixing rod 6 can be detachably connected by the bolt 7, so that it is not necessary to set them on the top of the second fixing rod 5 and the first fixing rod 6, which can save materials. Moreover, it can control the distance of the top of the second fixing rod 5 and the first fixing rod 6 from the top of the prefabricated stop block 1. After use, the fixing block 9 and the clamping block 10 can be removed to prevent the top of the second fixing rod 5 and the first fixing rod 6 from exceeding the top of the prefabricated stop block 1 too much, which can reduce the need for other personnel to operate the second fixing rod 5 and the first fixing rod 6.

[0032] A third groove 1.3 is provided at the top of the rear side of the through hole of the prefabricated block 1. A baffle 11 is independently installed in the third groove 1.3. When the baffle 11 is located in the third groove 1.3, it is used to separate the filter screen 3 and the ecological restoration layer. The ecological restoration layer is located on the rear side of the prefabricated block 1. The horizontal height of the bottom end of the third groove 1.3 is the same as the horizontal height of the bottom end of the through hole below the prefabricated block 1. When the baffle 11 is located in the third groove 1.3, it can block the upper and lower through holes. With the setting of the baffle 11, when the mounting frame 2 and the filter screen 3 are removed from the through hole on the prefabricated block 1, the baffle 11 can prevent the ecological restoration layer from being removed. The material slides down into the river channel through the through hole. Of course, there is only one baffle 11. The baffle 11 can be used repeatedly to alternately remove the mounting frame 2 and the filter screen 3 from the through hole of the prefabricated baffle 1. In order to prevent the filter screen 3 from being obstructed when it is in the through hole, when the second slide groove 1.1 is located on the side of the first slide groove 1.2, the third groove on the second slide groove 1.1 can be used for inserting the baffle 11. In this way, inserting the baffle 11 into the second slide groove 1.1 can prevent the baffle 11 from being lost. Of course, when the second slide groove 1.1 is located directly below the first slide groove 1.2, a placement groove for inserting the baffle 11 is opened on the side of the first slide groove 1.2.

[0033] Working principle:

[0034] In use, the installation method is consistent with that of the prefabricated retaining block in patent number CN202120596237.6. The prefabricated retaining block 1 is installed in the river channel, and an ecological restoration layer for slope repair is set on one side of the prefabricated retaining block 1. This ecological restoration layer includes a geotextile layer, a coarse biochar layer, a fine biochar layer, and a topsoil layer. A filter screen 3 is located in the through-holes on the prefabricated retaining block 1, allowing river water to seep into the ecological restoration layer through the through-holes. The filter screen 3 can block the materials in the ecological restoration layer. After a period of use, when the filter screen 3 becomes clogged by the materials in the ecological restoration layer or impurities in the river water, the baffle 11 is inserted into the third chute 1.3 to separate the filter screen 3 from the ecological restoration layer, preventing damage to the installation frame 2. After removal, the material in the ecological restoration layer slides down into the river channel through the through hole. Then, the upper installation frame 2 is removed from the first chute 1.2, and the lower installation frame 2 is removed from the second chute 1.1. The filter screen 3 in the installation frame 2 is then cleaned to remove the debris clogging the filter screen 3, or a new filter screen 3 is replaced. The cleaned filter screen 3 is then put back into the through hole on the prefabricated block 1, and the baffle 11 is removed from the third chute 1.3, so that the filter screen 3 blocks the ecological restoration layer again. The installation frame 2 is then removed from the top of the prefabricated block 1 through the second chute 1.1 and the first chute 1.2, thus cleaning the filter screen 3. The cleaning is relatively convenient and reduces the impact of the filter screen 3 clogging on the river water seeping into the ecological restoration layer.
