Description

Technical Field

[0001] This utility model relates to a river ecological structure and a riverbank protection structure. It is applicable to the field of river ecological construction technology. Background Technology

[0002] With urbanization, river channels need to be modified. To ensure that the modified channels meet the requirements for flood resistance and ecological sustainability, ecological restoration of the riverbanks is necessary. Currently, a common method is to pave the riverbanks with ecological blocks. Ecological blocks are easy to install, provide stable root systems for plant growth, and offer good greening effects. Small holes or grooves are pre-set in the ecological blocks to facilitate the movement of aquatic plants and animals. However, paving ecological blocks requires first installing fixed blocks on the riverbanks. Large-area paving of both fixed and ecological blocks is costly, and the connection strength between the ecological blocks and the riverbanks is relatively weak. Utility Model Content

[0003] The technical problem to be solved by this utility model is: to solve the above-mentioned technical problem, this utility model provides a river ecological structure and a riverbank protection structure.

[0004] The technical solution adopted in this utility model is: a river ecological structure, characterized by: an ecological pipe body, with a first cover plate and a second cover plate installed at both ends of the ecological pipe body to seal it; the first cover plate has a through fish passage hole, and the second cover plate is equipped with an anchor that can be inserted into the riverbed soil. In this way, the anchor facilitates the anchoring of the ecological pipe body into the riverbed soil, allowing water flow in the river to enter the ecological pipe body through the fish passage hole. The water flow inside the ecological pipe body is relatively slow, allowing aquatic organisms to enter through the fish passage hole to carry out their living activities, thus exhibiting good ecological benefits.

[0005] The anchor has a threaded rod mounted on the second cover plate, and a fixing member is installed on the threaded rod along its length. Thus, when the ecological pipe is laid on the riverbank, the threaded rod mounted on the second cover plate inserts into the riverbank soil, and the fixing member enhances the connection strength between the threaded rod and the riverbank soil.

[0006] The first and second cover plates have a first mounting hole and a second mounting hole respectively at positions corresponding to the threaded rod. The threaded rod passes through the first mounting hole on the first cover plate and the second mounting hole on the second cover plate. Nuts are installed at both ends of the threaded rod, and the two nuts engage with the first and second cover plates respectively. Thus, by passing the threaded rod through the first and second cover plates at both ends of the ecological pipe, installing the nuts at the ends of the threaded rod, and moving the two nuts to their engaging positions with the first and second cover plates, the first and second cover plates are clamped onto the ecological pipe by the action of the threaded rod and the two nuts.

[0007] Both the first and second cover plates have locking blocks on their sidewalls that contact the ecological pipe body, and both ends of the ecological pipe body have locking grooves that can mate with the locking blocks. In this way, by having the locking blocks on the first and second cover plates mate with the locking grooves on the ecological pipe body, it is easy to fasten the first and second cover plates to the ends of the ecological pipe body.

[0008] The ecological pipe is made of concrete, which gives it strong structural strength.

[0009] A riverbank protection structure includes the aforementioned river ecological structure, comprising a foundation block positioned at the bottom of the river channel, upon which the river ecological structure is stacked, with anchors for the river ecological structure inserted into the riverbank soil. Thus, by placing the foundation block on the riverbed and then stacking the river ecological structure on top, with its anchors embedded in the riverbank soil, the structural strength of the river ecological structure on the foundation block is enhanced, and the river ecological structure provides support for the riverbank.

[0010] The cross-section of the ecological tube is circular, and a groove is formed on the base block to fit the ecological tube. In this way, the ecological tube can be stably arranged on the base block by fitting with the groove on the base block, and it is also convenient to place the ecological tube of the upper layer between two ecological tubes of the lower layer, so that the ecological tubes on the base block have better structural stability.

[0011] Fastening holes are made on both side walls of the foundation block, and adjacent foundation blocks can be connected by fastening pins installed in the two fastening holes on the two foundation blocks. In this way, it is convenient to splice multiple foundation blocks together by fastening pins when the river channel is long.

[0012] The river ecological structure on the basic block is arranged in a stepped pattern. This results in the river's cross-section forming a trapezoid after the ecological structure is placed on the riverbank, giving the ecological structure on the riverbank better structural strength.

[0013] The beneficial effects of this utility model are as follows: By installing a first cover plate and a second cover plate at both ends of the ecological pipe, and forming fish passage holes on the first cover plate, aquatic organisms can easily enter the ecological pipe through the fish passage holes to live and engage in activities after the ecological pipe is placed in the river channel. By installing a threaded rod on the second cover plate and a fixing component on the threaded rod, the threaded rod can be anchored into the riverbank soil after the ecological pipe is placed on the riverbank, and the fixing component enhances the connection strength between the ecological pipe and the riverbank. By forming a first mounting hole and a second mounting hole on the first and second cover plates, the threaded rod can pass through both holes simultaneously, and a nut can be installed on the threaded rod. Thus, the two nuts and the threaded rod work together to clamp the first and second cover plates onto the ecological pipe. The utility model also features a first cover plate... The second cover plate has locking blocks on the side wall in contact with the ecological pipe body, and the ecological pipe body has locking grooves, which facilitates the locking of the first cover plate and the second cover plate onto the ecological pipe body through the cooperation of the locking blocks and the locking grooves; this utility model arranges foundation blocks at the bottom of the river, stacks the ecological pipe body on the foundation blocks, and inserts the threaded rods of the ecological pipe body into the riverbank soil, which facilitates the stable installation of the river ecological structure on the riverbank and provides good support for the riverbank; this utility model makes the cross-section of the ecological pipe body circular, and makes cylindrical ecological pipe bodies on the foundation blocks, which facilitates the arrangement of the ecological pipe bodies on the foundation blocks, and when arranging the upper layer of ecological pipe bodies on the lower layer of ecological pipe bodies, it is easy to place the upper layer of ecological pipe bodies between the two lower layer of ecological pipe bodies, and the lower layer of ecological pipe bodies limit the upper layer of ecological pipe bodies, resulting in better overall structural strength.

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0019] Example 1 illustrates a river ecological structure comprising an ecological pipe 410 with a circular cross-section. The ecological pipe 410 is open at both ends, with a first cover plate 430 and a second cover plate 420 installed at each end. Both the first cover plate 430 and the second cover plate 420 have locking blocks on their sidewalls in contact with the ecological pipe 410. Both ends of the ecological pipe 410 have locking grooves 411 that engage with the locking blocks. Specifically, the locking block on the first cover plate 430 is a first locking block 433, and the locking block on the second cover plate 420 is a second locking block 422. Thus, the engagement of the locking blocks and the locking grooves 411 facilitates the fastening of the first cover plate 430 and the second cover plate 420 to the ends of the ecological pipe 410.

[0020] In this embodiment, one or more fish passage holes 431 are formed on the first cover plate 430, so that after the ecological pipe body 410 is arranged in the river channel 100, aquatic organisms can easily enter the ecological pipe body 410 through the fish passage holes 431 to live and carry out activities.

[0021] In this embodiment, an anchor is installed on the second cover plate 420. When the ecological pipe body 410 is arranged on the riverbank 200 of the river channel 100, the anchor can be anchored into the soil of the riverbank 200, thereby playing a good role in fixing the ecological pipe body 410.

[0022] In this embodiment, the anchor has a threaded rod 421 mounted on the second cover plate 420, and at least one fixing member 423 is mounted on the threaded rod 421 along its length. The fixing member 423 is disc-shaped. Thus, after the threaded rod 421 is inserted into the soil of the riverbank 200, the fixing member 423 enhances the connection strength between the threaded rod 421 and the soil of the riverbank 200.

[0023] In this embodiment, a first mounting hole and a second mounting hole are respectively formed on the first cover plate 430 and the second cover plate 420 at positions corresponding to the threaded rod 421. The threaded rod 421 passes through the first mounting hole on the first cover plate 430 and the second mounting hole on the second cover plate 420. Nuts 432 are installed at both ends of the threaded rod 421, and the two nuts 432 cooperate with the first cover plate 430 and the second cover plate 420 respectively. In this way, after the first cover plate 430 and the second cover plate 420 are snapped onto the ecological tube body 410, tightening the nuts 432 at both ends of the threaded rod 421 clamps the ecological tube body 410, the first cover plate 430 and the second cover plate 420 together, which can prevent the first cover plate 430 and the second cover plate 420 from falling off the ecological tube body 410.

[0024] In this embodiment, the ecological pipe 410 is a concrete pipe, which provides high structural strength.

[0025] Example 2 is a riverbank protection structure. It has a foundation block 300 arranged at the bottom of the river channel 100. The foundation block 300 is buried in the riverbed to a depth not less than 1.5 times the theoretically calculated maximum scour depth. A river ecological structure 400 is stacked on the foundation block 300. The threaded rod 421 and fixing component 423 of the river ecological structure 400 are anchored into the soil of the riverbank 200 of the river channel 100.

[0026] In this embodiment, fastening holes 320 are formed on both side walls of the base block 300. Two adjacent base blocks 300 can be connected by fastening pins 330 installed in the two fastening holes 320 on the two base blocks 300. In this way, when applied to a longer river channel 100, multiple base blocks 300 can be spliced ​​together by fastening pins 330, making it suitable for river channels 100 of different lengths.

[0027] In this embodiment, a groove 310 is formed on the base block 300 to fit with the side wall of the cylindrical ecological tube 410. Thus, when the ecological tube 410 is placed on the base block 300, the ecological tube 410 fits with the groove 310 on the base block 300, making it easy to install the ecological tube 410 on the base block 300.

[0028] In this embodiment, ecological pipes 410 are stacked on the base block 300, with the upper layer of ecological pipes 410 staggered with the lower layer of ecological pipes 410, with the upper layer of ecological pipes 410 positioned between two lower layer ecological pipes 410. Thus, when the upper layer of ecological pipes 410 is placed on top of the lower layer of ecological pipes 410, the two adjacent lower layer ecological pipes 410 act as a limiting force on the upper layer ecological pipes 410, facilitating installation, while also providing better overall structural strength for the ecological pipe system 410.

[0029] In this embodiment, the river ecological structure 400 on the base block 300 is arranged in a stepped manner. This results in the river 100 having a trapezoidal cross-section after the river ecological structure 400 is placed on the riverbank 200 of the river 100, and the river ecological structure 400 on the riverbank 200 of the river 100 has better structural strength.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
