Description

Technical Field

[0001] This utility model relates to the field of ecological restoration technology, specifically to a plate anchor pile and a device including the plate anchor pile. Background Technology

[0002] Wave-damping devices are engineering structures used to reduce or eliminate water waves. They typically consist of floating structures (such as pontoons and floating rafts), rigid barriers (such as wave-damping walls and breakwaters) or flexible materials (such as vegetation buffers), and anchor piles to secure the floating structures. Their core purpose is to reduce the impact of waves on shorelines, ecosystems, or man-made structures through physical obstruction or energy dissipation. Traditional wave-damping devices focus more on the construction of the floating structures, with little specific design and optimization for the anchor piles. However, anchor piles play a crucial role in wave-damping devices, especially in large lakes with strong winds and waves. Insufficient anchoring can easily lead to the floating structures being displaced by wind and waves, thus losing their wave-damping function. Furthermore, barriers are facilities placed in water bodies to separate water areas and purify water quality. The upper part of the barrier is usually fixed using a buoyancy structure, while the lower part requires counterweights or anchor piles for anchoring. When wind and waves are strong, these counterweights or anchors are also prone to failure.

[0003] Chinese patent application CN106351172B discloses a flexible breakwater system where the anchor pile is a block weight without any special design. Its anchoring effect depends on the weight of this block weight. Therefore, in areas with extremely high winds and waves, large-volume weights must be used, but these large weights can easily damage the growth of submerged vegetation in the area. Furthermore, CN222044176U discloses an expansion mechanical anchor pile, which is fixedly buried in hard soil. It mainly includes a middle plate, side plates, T-shaped ends, and jacks. Its working principle is that the jacks apply pressure to the side plates, causing them to expand outwards, thereby compressing the surrounding soil and achieving an anchoring effect. This anchor pile structure is overly complex; each anchor pile must be equipped with a jack to apply pressure for installation. It is also easily affected by soil structure; if the hard soil layer is too deep, the length of the anchor pile must be increased, resulting in poor applicability. Utility Model Content

The plate anchor pile has a simple structure, can be installed in hard soil layers with minimal damage to submerged vegetation at the bottom of the water, can adapt to hard soil layers of any depth, and is easy to install. After installation, the angle between the main structure of the plate anchor pile and the vertical plane can be adjusted by the pulling direction of the anchor rope, thereby increasing the resistance of the soil acting on the anchor pile. It can provide a stable anchoring effect for wave-damping devices or barriers to resist the working environment of strong winds and waves. It solves the technical problems of existing anchor piles being too simple in structure, occupying a large area at the bottom of the water, or having an overly complex structure and being difficult to install.

The lower end of the sleeve (2) is close to the lower end of the flat plate (1), and its upper end is close to the upper end of the flat plate (1).

[0009] An anchor rope connecting ring (3) is provided on the first side (11) or the second side (12), and the anchor rope connecting ring (3) is located near the middle of the flat plate (1); the anchor rope connecting ring (3) includes at least two rings; when the two rings are located on the first side (11), the two rings are located on both sides of the sleeve (2); when the two rings are located on the second side (12), the two rings are located on both sides of the projection position of the sleeve (2) on the second side (12); the lower end of the flat plate (1) is a pile head (13), and the pile head (13) is set in a pointed shape.

[0010] According to a preferred embodiment of the present invention, the distance from the anchor rope connecting ring (3) to the lower end of the flat plate (1) is 1 / 3 to 2 / 3 of the total length of the flat plate (1).

[0011] According to a preferred embodiment of the present invention, the pile head (13) of the flat plate (1) is further provided with pile head reinforcing ribs (14).

[0012] According to a preferred embodiment of the present invention, the pile head reinforcing bar (14) is a sloping convex ridge that gradually thickens from the tip of the pile head (13) toward the middle of the flat plate (1).

[0013] According to a preferred embodiment of the present invention, the beveled ridge is integrally connected to the lower end of the sleeve (2).

[0014] According to a preferred embodiment of the present invention, the flat plate (1) is a hexagonal plate with a thickness of 1 / 5 to 1 / 10 of the length of one side of the hexagonal plate.

[0018] Secondly, this utility model also relates to a wave-dissipating device or barrier for plate anchor piles comprising any of the above embodiments.

[0019] (III) Beneficial Effects

[0020] During the installation of the plate anchor pile of this utility model, the anchor rope needs to be passed through the anchor rope connecting ring first, and the pile driving rod is inserted into the casing. The pile head of the anchor pile is facing down, and the plate body is perpendicular to the mud surface of the lake bottom or river bottom. The pile driving rod is struck with a pile driver or hammer to completely embed the anchor pile into the solid soil (hard soil layer). Then the pile driving rod is pulled out from the casing, leaving the anchor pile in the hard soil layer. The outer end of the anchor rope is pulled in a direction that forms a certain angle (greater than 0 degrees) with the vertical direction, or the outer end of the anchor rope is connected to the object to be fixed (such as a buoyant structure). Because the anchor rope forms a certain angle with the vertical direction, the flat plate of the anchor pile tilts and is no longer vertical. This increases the resistance (anchoring force) of the surrounding soil on the anchor pile in the opposite direction of the anchor rope's pulling direction, allowing the anchor pile to be stably fixed in the hard soil layer. This can provide a stable anchoring effect for the floating structure of the wave-damping device to resist the working environment of strong winds and waves. It solves the technical problems of existing anchor piles being too simple, occupying a large area on the bottom of the water, or being too complex and difficult to install.

[0021] During the process of driving anchor piles into hard soil layers, the pile head reinforcement can increase the strength of the pile head and protect it from damage when it encounters hard objects. Attached Figure Description

[0027] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] like Figure 1 As shown, this utility model provides a plate anchor pile, which includes a plate body 1. The plate body 1 has a first side 11 and a second side 12. A sleeve 2 for a piling rod to be fitted is installed on the first side 11. The lower end of the sleeve 2 is close to the lower end of the plate body 1, and the upper end is close to the upper end of the plate body 1. The length of the sleeve 2 preferably accounts for about 1 / 2 to 2 / 3 of the total length of the plate body 1. This design facilitates a stable fit between the piling rod and the plate body 1, enabling efficient piling operations.

[0030] An anchor rope connecting ring 3 is provided on either the first side 11 or the second side 12 of the flat plate 1, with the anchor rope connecting ring 3 located near the middle of the flat plate 1. The anchor rope connecting ring 3 comprises at least two rings. When these two rings are located on the first side 11, they are respectively located on both sides of the sleeve 2; if located on the second side 12, they are respectively located on both sides of the projection position of the sleeve 2 on the second side 12. This symmetrical distribution design allows for a more uniform force distribution after the anchor rope is connected, improving the stability of the anchor pile. Preferably, the distance from the anchor rope connecting ring 3 to the lower end of the flat plate 1 is 1 / 3 to 2 / 3 of the total length of the flat plate 1. This range helps to ensure the balance of the anchor pile under stress. Preferably, the anchor rope connecting ring 3 is located on the side with the sleeve 2.

[0031] The lower end of the flat plate 1 is the pile head 13, which is designed with a pointed shape to facilitate easier insertion into the soil or other media during pile driving. To enhance the strength of the pile head 13, a pile head reinforcing rib 14 is also provided. The pile head reinforcing rib 14 is a sloping ridge that gradually thickens from the tip of the pile head 13 towards the middle of the flat plate 1, and this sloping ridge is integrally connected to the lower end of the casing 2. This design not only increases the impact resistance and strength of the pile head 13, but also makes the connection between the casing 2 and the flat plate 1 more stable. The pile head reinforcing rib 14, like a sharp wedge edge, starts from the tip of the pile head 13, extends smoothly and with a certain inclination towards the middle of the flat plate 1, and connects to the lower end of the casing 2.

[0032] The flat plate 1 is a hexagonal plate with a thickness of 1 / 5 to 1 / 10 of the length of one side of the hexagonal plate. This shape and size design ensures that the flat plate 1 has sufficient strength and stability, while also reducing the overall weight of the anchor pile to a certain extent, making it easier to transport and install.

[0033] The plate anchor pile's plate body 1, sleeve 2, and pile head reinforcing rib 14 are manufactured using a one-piece cast iron molding process, which ensures the connection strength and integrity between the parts. The anchor rope connecting ring 3 is fixed by integral molding with the plate body 1, welding, or bolting. Both connection methods have high reliability and can meet different usage requirements.

[0034] like Figure 2 As shown, during the installation of the plate anchor pile of this utility model, the anchor rope 4 needs to be passed through the anchor rope connecting ring 3 first, and the pile driving rod 5 is inserted into the sleeve 2. The pile head 13 of the anchor pile faces downward, and the flat plate 1 is kept perpendicular to the mud surface of the lake or river bottom. The pile driving rod 5 is struck with a pile driver or hammer to fully embed the anchor pile into the hard soil layer. Then, the pile driving rod is pulled out from the sleeve 2, leaving the anchor pile in the hard soil layer. During the process of driving the anchor pile into the hard soil layer, the pile head reinforcing rib 14 can improve the strength of the pile head, protect the pile head from damage when it encounters hard objects, and also shift the geometric center of gravity of the plate anchor pile to the position of the pile head 13. This makes it easier to keep the anchor pile vertical during pile driving. Since the geometric center of gravity of the plate anchor pile is at the position of the pile head 13, the flat plate 1 of the anchor pile is more likely to flip and tilt when the anchor rope 4 is pulled, which helps to generate a larger frictional resistance between the soil and the anchor pile in the opposite direction to the pulling direction of the anchor rope 4.

[0035] like Figure 3As shown, after the anchor pile is placed at a predetermined position in the hard soil layer, the anchor rope 4 is pulled along a direction forming a certain angle (greater than 0 degrees) with the vertical direction, or the outer end of the anchor rope is fixedly connected to the object to be fixed (such as a buoyancy structure) along a direction forming a certain angle with the vertical direction, and the anchor rope forms a certain angle with the vertical direction (the angle is greater than 0 degrees and less than 90 degrees). Because the anchor rope 4 forms a certain angle with the vertical direction, when an external force pulls the anchor rope 4 or the object to be fixed tries to move under the action of wind and waves, the pulling action of the anchor rope 4 causes the flat plate 1 of the anchor pile to tilt and no longer be vertical, so that the surrounding soil generates resistance to the anchor pile in the opposite direction of the anchor rope pulling direction, and the magnitude of this resistance is positively correlated with the angle of the anchor rope 4 relative to the vertical direction, so that the anchor pile can be stably fixed in the hard soil layer, which can provide a stable anchoring effect for the floating structure of the wave-dissipating device to resist the working environment of strong winds and waves.

[0036] The plate anchor pile of this embodiment has a simple structure, is installed in hard soil layers, and causes minimal damage to submerged vegetation during installation (vertical driving with the pile head facing downwards). It can adapt to hard soil layers of any depth, is easy to install, and after installation, the angle between the main structure of the plate anchor pile and the vertical plane can be adjusted by the pulling direction of the anchor rope, thereby increasing the resistance of the soil acting on the anchor pile. It can provide stable anchoring for the floating structure of wave-damping devices to resist the working environment of strong winds and waves. It solves the technical problems of existing anchor piles, such as overly simple structures, large underwater area occupation, or overly complex structures that are difficult to install. When it is necessary to remove the plate anchor pile from the soil, it can be removed and retrieved simply by pulling it vertically upwards. The plate anchor pile of this utility model has a wide range of applications. It can be used to provide anchoring force for buoyancy structures on water, and can also provide anchoring force for agricultural greenhouses, tents, and other buildings. The anchor pile has a simple structure and high economic production cost.

[0037] Application examples

[0038] The lateral area of ​​the flat plate 1 of the sheet anchor pile is set to 0.05㎡. It is integrally cast from cast iron to form the flat plate 1, pile head reinforcing rib 14, anchor rope connecting ring 13, and sleeve 2. The anchor rope 4 is made of 8mm diameter stainless steel wire rope. Field surveys show a water depth of 1.3m, a 30cm thick floating mud layer, a 20cm thick silt layer, and a hard soil layer 50cm below the mud layer. The normal tidal range is 20cm, and the flood season water level rises by 1 meter. The angle between the anchor rope 4 and the mud surface (horizontal plane) is 45°, therefore the anchor rope length is 4.3 meters. After connecting the anchor rope 4 to the sheet anchor pile, a steel pipe is inserted into the sleeve 2. The steel pipe is then driven into the hard soil using a pile driver. The embedment depth of the sheet anchor pile is determined by the change in the length of the wire rope. Once the hard soil layer is reached, the steel pipe is pulled out. After connecting the anchor rope 4 to the tension gauge, a crane was used to apply tension to the anchor rope 4. The measured tension reached 18000N before the plate anchor pile was pulled out. This shows that the anchoring effect of the plate anchor pile is excellent.
