In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0039] In order to solve the above technical problems, Figure 1-5 As shown, the present invention designs a low-cost, easy-to-construct fence-type bank and slope protection structure, including an arrow pile unit module. Specifically, the arrow pile unit module includes a tube 1, an arrow insertion portion 2, and a connector 3. The tube 1 is preferably made of plastic material. The plastic structure has a low manufacturing cost and is easy to form. Compared with metal materials, it has better corrosion resistance and a certain impact resistance and tensile strength while being lighter. The height of the tube 1 can be about 2-6 meters, and the wall thickness is about 2 mm, which can be determined according to the actual situation of the river bank soil layer. The higher the height, the deeper the depth of the soil layer can be driven into, making the structure more stable.

[0040] The diameter of the arrow insertion portion 2 gradually decreases from top to bottom and gradually converges into a tip, and its structure is approximately a cone, so that its tip is perpendicular to the soil layer and can be penetrated by applying pressure from top to bottom. Considering that the prefabricated arrow pile structure needs to be pressed into the soil layer before filling the cement mortar mixture, and the tip of the arrow insertion portion 2 receives a large pressure during the pressing process, it is easy to break or wear. Preferably, a solid tip 21 is provided at the bottom of the arrow insertion portion 2, and the overall height of the arrow insertion portion 2 is about 20-30 cm, while the height of the solid structure is about 5 cm. The solid structure can enhance the strength and rigidity of this part, improve its stability in use, and avoid breakage.

[0041] The connector 3 in this embodiment includes an outer sleeve 31, the height of the outer sleeve 31 is about 12 cm, and the outer sleeve 31 is provided with a limit block 32 protruding inwardly. The outer diameter of the tube 1 is the same as the outer diameter of the top of the arrow insertion part 2. The tube 1 and the arrow insertion part 2 are clamped on the upper and lower sides of the outer sleeve 31 respectively. The bottom end of the tube 1 contacts the upper surface of the limit block 32, and the top of the arrow insertion part 2 contacts the lower surface of the limit block 32. The connector 3 can quickly connect the tube 1 with the arrow insertion part 2. Since the prefabricated arrow pile composed of the tube 1 and the arrow insertion part 2 is only subjected to pressure from top to bottom during construction and installation, the expansion and pressing effect of each component can be better and the connection is stable.

[0042] The inner hole of the tube 1 communicates with the inner cavity of the arrow insertion part 2 to form a structural cavity for injecting the filler 5. The inner hole of the tube 1 is provided with a support framework 4. The support framework 4 is in a cylindrical structure. In this embodiment, the support framework 4 can be made of materials such as steel pipes, steel bars, and bamboo. Its specific selection depends on the actual situation of the riverbank. Materials such as steel bars and steel pipes have better and more stable support effects as skeletons but relatively higher costs, and are suitable for large river basins. When the slope protection in some small rivers is not under much pressure, materials such as bamboo can be selected as supports, with lower costs. The filler 5 is a mortar mixture, which is mainly a mixture prepared by mixing sand with other additives such as cement and lime in a certain proportion. After cement is mixed with water, a hydration reaction occurs, generating hardening substances. These hardening substances can fill the voids between the aggregates, thereby improving the structural strength and stability of the entire arrow pile unit module.

[0043] Furthermore, the arrow pile unit module further includes a cap 6. The cross-section of the cap 6 is in a U-shaped structure. The cap 6 covers the top of the tube 1 to seal the top opening of the tube 1. The upper surface of the cap 6 is in a planar structure. The setting of the cap 6 can, on the one hand, prevent the inner hole of the tube 1 from being exposed, and on the other hand, can also improve the overall aesthetics and coordination. In a possible implementation scheme, the cap 6 can be fixed by means of threaded connection, and the installation connection is more stable and not easy to separate.

[0044] During specific implementation, a plurality of the arrow pile unit modules are arranged at equal intervals along the length direction of the riverbank, and a mudguard 7 is provided between every two adjacent arrow pile unit modules. The mudguard 7 is preferably fixedly connected to the outer wall of the tube 1 of the arrow pile unit module through bolt members, which is convenient for disassembly and assembly. The arrow pile unit module can reduce the cross-section of the base soil and increase the firmness of the arrow pile under the base soil. The mudguard 7 can be made of external building formwork, or stone plastic board and integrated plastic wallboard used for interior decoration. The setting of the mudguard 7 can prevent soil erosion, play a role in slope protection, and prevent the riverbank slope from being washed. The arrow pile unit module can support the mudguard 7, and several drainage holes are left on the plate surface to ensure the discharge of groundwater.

[0045] In another possible implementation scheme, as Figure 4 shown, a cross-shaped strengthening support body 41 is formed inside the support framework 4. The strengthening support body 41 divides the inner hole of the support framework 4 into four small chambers. Therefore, a number of filling layer distribution areas can be formed both between the tube 1 and the support framework 4 and inside the support framework 4, and cooperate with each other to squeeze to further improve the strength and hardness of the final structure.

[0046] In another possible implementation scheme, as Figure 5As shown, in this embodiment, the connector 3 includes an inner tube 33, the upper and lower parts of which are provided with external threads, and the middle part is provided with a protruding block 34, the outer diameter of the block 34 is matched with the outer diameter of the tube 1 and the top of the arrow insertion part 2, and the bottom of the tube 1 and the top of the arrow insertion part 2 are provided with internal threaded holes connected to the connector 3. The threaded connection method is more stable and convenient for disassembly and assembly, and this connection method makes the outer side of the prefabricated arrow pile structure no longer have a protruding structure, the overall structure is more coordinated and easy to install and insert into the soil layer.

[0047] In another possible implementation, considering that simply lengthening the length of the tube 1 of the arrow pile unit module will increase the difficulty of construction and make transportation inconvenient, when the depth of pile foundation needs to be lengthened to improve stability in areas with severe erosion and strong hydraulic power, it is only necessary to connect several sections of the tube 1 up and down through pipe connectors to increase the overall height of the arrow pile unit module, and the specific number of connections can be determined according to actual conditions.

[0048] The present invention relates to a construction method of a low-cost and easy-to-construct fence-type bank and slope protection structure, comprising the following steps:

[0049] S1. Determine the scope of construction and delineate the construction area. Determine the spacing between adjacent arrow pile unit modules based on the actual stress conditions of the river bank and then delineate the marking area. In large river basins with fierce water flow, the spacing between adjacent arrow piles can be reduced and the distribution can be more dense to improve strength.

[0050] S2, the tube 1 is fixedly connected to the arrow insertion part 2 through the connector 3 to form a prefabricated arrow pile structure;

[0051] S3, pre-pressing and fixing a plurality of prefabricated arrow pile structures in each of the designated marked areas;

[0052] S4, after connecting the pile driving equipment with the pressure head, sinking and pressing each prefabricated arrow pile until it reaches a predetermined depth and then stops. The pressure head mold adopts an inner plug type pressure head, that is, a T-type pressure head;

[0053] S5, placing a support frame 4 into the inner hole of the tube 1 of each prefabricated arrow stake;

[0054] S6, using the injection pump in the cement mixer to fill the cement mortar mixture into the structural cavity of the prefabricated arrow pile and make the upper layer flush with the upper surface of the tube 1;

[0055] S7, after the cement mortar filler 5 is hardened, the cap 6 is put on to form the final arrow pile unit module;

[0056] S8, installing a fender 7 between two adjacent arrow pile unit modules, and fixing the fender 7 to the outer wall of the tube 1 of the arrow pile unit module by bolts;

[0057] S9, perform earth filling operation to cover the fender 7 stably.

[0058] The advantage of this bank and slope protection structure is that it is flexible in construction and can be designed according to the terrain of the river channel and river slope without being restricted by the terrain. It greatly simplifies the construction difficulty and reduces the construction cost while improving the protection effect. It is sturdy, durable and has a long service life. It occupies a small area and makes full use of the space. It has good flood control and flood discharge performance. The size and height of the overall structure of the bank and slope protection can be adjusted according to the actual situation of the slope. It is not easy to grow covering plants, which makes the water flow in the river faster. The damaged positions can be repaired and replaced separately, which is convenient and quick. The appearance color can change with the slope and is more beautiful. This bank and slope protection structure has a wide range of applications, and can be used for water, fields, and mountains.

[0059] It is worth noting that the technical features such as pile driving equipment, mixer, cement mortar mixture, etc. involved in the patent application of this invention should be regarded as prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected by conventional methods in the field, and should not be regarded as the inventive point of this patent. This patent will not be further elaborated.

[0060] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made by technicians in the relevant technical field based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
