Description

Technical Field

[0001] This application relates to the field of new energy solar power generation engineering technology, and in particular to a PHC pipe pile structure suitable for flexible support solar-fishery complementary systems. Background Technology

[0002] In the flexible support system for fish farming and solar power integration, PHC pipe piles, as the core foundation component, must not only cope with the silty soft soil foundation commonly found in fishpond areas to ensure the depth and stability of the pipe piles in the soil; but also bear the composite load transmitted by the large-span support; and withstand the strong horizontal thrust brought by a category 12 typhoon to avoid risks such as tilting or uplift of the pipe piles. These three aspects together constitute the core performance adaptation target of PHC pipe piles.

[0003] Because pile driving is inefficient and the required depth is difficult to achieve on soft soil foundations. The surface of fishponds is mostly silty soft soil. Traditional PHC pipe piles rely on static pressure or hammer driving. Static pressure driving is prone to causing the pipe pile to tilt due to high soil resistance, while hammer driving is prone to causing cracks in the pipe pile concrete. Floating piles are also prone to occur during the sinking process. Utility Model Content

[0004] This application provides a PHC pipe pile structure suitable for flexible support solar-fishery integration, in order to solve the problem that traditional static pressure pile driving is prone to tilting and concrete cracking due to high soil resistance, thereby improving the pull-out resistance and overall stability of PHC pipe piles.

[0005] To achieve the above and other related objectives, this utility model provides a PHC pipe pile structure suitable for flexible support solar-aquaculture integration, comprising:

[0006] PHC pipe piles have end caps fixedly connected to their tops. The PHC pipe piles are located at both ends of the PHC pipe pile structure. The surface of the PHC pipe piles is provided with stabilizing mechanisms, and the interior of the PHC pipe piles is provided with auxiliary mechanisms.

[0007] The middle section has an end section fixedly connected to its top, and the middle section is located between the two PHC pipe piles at both ends;

[0008] Steel strands and steel wire ropes are sleeved on the surface of the end frames and connected between adjacent end frames. The outer two end frames are fixedly connected to diagonal tie rods at the ends away from the middle frame.

[0009] In one embodiment of this utility model, it further includes:

[0010] Trusses are fixedly connected between adjacent end frames, and adjacent trusses are flexibly connected by steel strands and wire ropes.

[0011] In one embodiment of this utility model, the auxiliary mechanism includes:

[0012] A chute is formed around the inner wall of the PHC pipe pile;

[0013] A truncated cone, which is fixedly connected to the inner ring of the PHC pipe pile;

[0014] An electric actuator is fixedly connected to the bottom of the frustum;

[0015] A cross-shaped component is fixedly connected to the bottom of the electric actuator.

[0016] The motor is fixedly connected to the bottom of the cross;

[0017] The rotating rod is fixedly connected to the bottom of the motor;

[0018] A cross plate is fixedly connected to the bottom of the rotating rod, and sliding blocks are fixedly connected to the four sides of the cross plate.

[0019] In one embodiment of this utility model, there are four slide blocks and four slide grooves, and the four surfaces of the slide blocks and the interior of the slide grooves are slidably connected.

[0020] In one embodiment of this utility model, the cross plate is disposed at the bottom of the PHC pipe pile, and the outer circle of the cross plate is larger than the inner circle of the PHC pipe pile.

[0021] In one embodiment of this utility model, the stabilizing mechanism includes:

[0022] A fixing plate is fixedly connected to the left and right surfaces of the PHC pipe pile, and a hinge plate is hinged to the bottom of the fixing plate near the PHC pipe pile.

[0023] The hinge plate has a retaining ring hinged to its bottom.

[0024] The insertion rod is fixedly connected to the inner ring of the fixing ring;

[0025] The drill bit is fixedly connected to the bottom of the insertion rod;

[0026] A connecting plate is fixedly connected to the top of the insertion rod, and screws are threadedly connected to the connecting plate and the fixing plate.

[0027] In one embodiment of this utility model, a through-hole groove is provided inside the fixing plate, and the surface of the insertion rod is inserted through the through-hole groove provided inside the fixing plate.

[0028] In one embodiment of this utility model, the connecting plate is disposed on the top of the fixing plate, and the fixing ring is disposed between the fixing plate and the drill bit.

[0029] In one embodiment of this utility model, the truss includes triangular struts and X-shaped struts.

[0030] In one embodiment of this utility model, the PHC pipe pile is a precast concrete pipe pile.

[0031] As described above, the PHC pipe pile structure of this utility model, suitable for flexible support and solar-fishery complementary systems, has the following beneficial effects:

[0032] (1) The present invention provides a PHC pipe pile structure suitable for flexible support and solar-fishery complementarity. Through an auxiliary mechanism, the electric push rod piston rod extends downward and pushes the cross to slide along the groove on the inner wall of the PHC pipe pile to ensure that the cross moves smoothly up and down. The cross drives the motor, rotating rod and cross plate to descend synchronously. While the cross plate rotates, it applies a downward drilling force to assist the PHC pipe pile to sink quickly to the target depth of soil under its own weight and external force.

[0033] (2) The present invention provides a PHC pipe pile structure suitable for flexible support fishery-solar complementary use. Through the stabilizing mechanism, after the PHC pipe pile is inserted into the soil, the connecting plate is pressed down, so that the insertion rod drives the drill bit to drill into the soil around the PHC pipe pile under pressure. At the same time, with the assistance of the hinge plate, the shaking of the insertion rod can be limited, ensuring that the drill bit drills vertically into the soil and avoiding bending of the insertion rod.

[0034] (3) The present invention provides a PHC pipe pile structure suitable for flexible support and solar-fishery complementarity. The inclined tie rod at one end of the outer end frame is connected to the end frame of the adjacent pipe pile, which can balance the unidirectional tension of the steel strand on the pipe pile, avoid the pipe pile tilting due to excessive unilateral tension, and further improve the overall stability of the pipe pile.

[0043] Please see Figure 1 , Figure 1 This is a three-dimensional view of the overall structure of a PHC pipe pile structure suitable for flexible support solar-fishery integration according to this utility model. The utility model provides a PHC pipe pile structure suitable for flexible support solar-fishery integration, comprising: a PHC pipe pile 1 with an end frame 3 fixedly connected to its top; the PHC pipe pile 1 is disposed at both ends of the PHC pipe pile structure; a stabilizing mechanism 2 is disposed on the surface of the PHC pipe pile 1; an auxiliary mechanism 4 is disposed inside the PHC pipe pile 1; a middle frame 5 with an end frame 3 fixedly connected to its top; the middle frame 5 is disposed between the two PHC pipe piles 1 at both ends; steel strands 7 and steel wire ropes 8 are sleeved on the surface of the end frame 3 and connected between adjacent end frames 3; and diagonal tie rods 6 are fixedly connected to the ends of the two outer end frames 3 away from the middle frame 5.

[0044] A PHC pipe pile structure suitable for flexible support solar-fishery integration further includes: trusses 9 are fixedly connected between adjacent end frames 3, and adjacent trusses 9 are flexibly connected by steel strands 7 and steel wire ropes 8.

[0045] Please see Figure 2 , Figure 3 , Figure 2This is a schematic diagram of the PHC pipe pile and auxiliary mechanism composition structure of a flexible support-based solar-fishery complementary PHC pipe pile structure according to the present invention. Figure 3 This utility model relates to a PHC pipe pile structure suitable for flexible support solar-aquaculture integration. Figure 2 Enlarged structural diagram at point A; the auxiliary mechanism 4 includes: a sliding groove 41 formed around the inner wall of the PHC pipe pile 1; a frustum 48 fixedly connected to the inner ring of the PHC pipe pile 1; an electric push rod 47 fixedly connected to the bottom of the frustum 48; a cross 46 fixedly connected to the bottom of the electric push rod 47; a motor 45 fixedly connected to the bottom of the cross 46; a rotating rod 44 fixedly connected to the bottom of the motor 45; a cross plate 43 fixedly connected to the bottom of the rotating rod 44; and sliding seats 42 fixedly connected around the cross 46.

[0046] Specifically, there are four slide blocks 42 and four slide grooves 41, and the surfaces of the four slide blocks 42 and the interior of the slide grooves 41 are slidably connected.

[0047] Specifically, the cross plate 43 is disposed at the bottom of the PHC pipe pile 1, and the outer circle of the cross plate 43 is larger than the inner circle of the PHC pipe pile 1.

[0048] In one embodiment of this utility model, the electric pusher piston rod extends downward and pushes the cross 46 to slide along the groove 41 on the inner wall of the PHC pipe pile 1, ensuring that the cross moves smoothly up and down. The cross drives the motor, rotating rod and cross plate to descend synchronously. While the cross plate rotates, it applies a downward drilling force to assist the PHC pipe pile 1 to sink quickly to the target depth under its own weight and external force.

[0049] Please see Figure 4 , Figure 4 This is a schematic diagram of a stabilizing mechanism for a PHC pipe pile structure suitable for flexible support solar-aquaculture integration according to this utility model. The stabilizing mechanism 2 includes: a fixing plate 26 fixedly connected to the left and right surfaces of the PHC pipe pile 1, and a hinge plate 25 hinged to the bottom of the fixing plate 26 near the PHC pipe pile 1; a fixing ring 23 hinged to the bottom of the hinge plate 25; an insertion rod 22 fixedly connected to the inner ring of the fixing ring 23; a drill bit 24 fixedly connected to the bottom of the insertion rod 22; and a connecting plate 21 fixedly connected to the top of the insertion rod 22. Screws 27 are threadedly connected to the connecting plate 21 and the fixing plate 26.

[0050] Specifically, the fixing plate 26 has a through-hole groove inside, and the insertion rod 22 is inserted through the through-hole groove inside the fixing plate 26.

[0051] Specifically, the connecting plate 21 is disposed on the top of the fixing plate 26, and the fixing ring 23 is disposed between the fixing plate 26 and the drill bit 24.

[0052] In one embodiment of this utility model, after the PHC pipe pile 1 is inserted into the soil, the connecting plate 21 is pressed down, so that the insertion rod drives the drill bit 24 to drill into the soil around the PHC pipe pile 1 under pressure. At the same time, with the assistance of the hinge plate 25, the shaking of the insertion rod can be limited, ensuring that the drill bit drills vertically into the soil and preventing the insertion rod from bending.

[0053] In one embodiment of this utility model, during actual operation, when a PHC pipe pile structure suitable for flexible support fishery-solar complementary use is used, during the driving process of PHC pipe pile 1, the motor 45 is started, the motor 45 drives the rotating rod 44 to rotate, and the rotating rod 44 synchronously drives the cross plate 43 to rotate. When the cross plate 43 rotates, its end can break the soft soil or silt on the surface of the fishpond, reducing the soil resistance when the pipe pile sinks.

[0054] In one embodiment of this utility model, the electric push rod 47 is activated, and the piston rod of the electric push rod extends downward, pushing the cross 46 to slide along the groove 41 on the inner wall of the PHC pipe pile 1, ensuring that the cross 46 moves smoothly downward. The cross 46 drives the motor 45, the rotating rod 44, and the cross plate 43 to descend synchronously. While rotating, the cross plate 43 applies a downward drilling force, assisting the PHC pipe pile 1 to quickly sink to the target depth under its own weight and external force. After the PHC pipe pile 1 reaches the preset depth, the electric push rod 47 is activated in reverse, driving the cross 46, the motor 45, and the cross plate 43 to rise into the interior of the PHC pipe pile 1 to avoid affecting the subsequent operation of the stabilizing mechanism. The motor stops rotating, and the auxiliary mechanism completes the task of assisting in the sinking.

[0055] In one embodiment of this utility model, after the PHC pipe pile 1 is inserted into the soil, the connecting plate 21 is pressed down, so that the insertion rod drives the drill bit 24 to drill into the soil around the PHC pipe pile 1. At the same time, with the assistance of the hinge plate 25, the shaking of the insertion rod can be limited, ensuring that the drill bit drills vertically into the soil and preventing the insertion rod from bending.

[0056] In one embodiment of this utility model, after the PHC pipe pile 1 is driven into the ground, the system load is evenly transferred to the pipe pile through the flexible support connected by the end frame. At the same time, it works with the truss to ensure the long-term stability of the pipe pile. The top of the PHC pipe pile 1 is fixedly connected to the end frame 3 at the top of the middle frame 5. The steel strand 7 (1860 grade) and the steel wire rope 8 are sleeved on the surface of the end frame. The tension of the upper cable load steel strand of the flexible support is transferred to the pipe pile through the end frame. The distributed connection design of the end frame can avoid the load from being concentrated at a certain point on the top of the pipe pile and prevent the concrete at the top of the pipe pile from cracking.

[0057] In one embodiment of this utility model, the end frame 3 is fixedly connected to the truss 9. The truss 9 consists of triangular struts and X-shaped struts. The support foundation uses prestressed high-strength precast concrete pipe piles of types such as PHC-300-AB-70, PHC-500-AB-100, PHC-500-B-100, and PHC-600-AB-110, with pile lengths of approximately 7.0m-13.5m, a soil penetration depth >5.7m, and an exposed length <7.3m (0.87m for anchor piles). When a Category 12 typhoon generates horizontal thrust, the thrust is transmitted to the end frame through the flexible support. The end frame disperses the horizontal force to the truss, which then transmits the force to the end frames of adjacent pipe piles, forming a multi-pipe pile collaborative wind-resistant network. At the same time, the end frame can restrict the horizontal displacement of the pipe piles. Combined with the insertion rods of the stabilizing mechanism, this ensures that the pipe piles can displace under horizontal wind loads, meeting the system's wind resistance requirements.

[0058] In one embodiment of this utility model, the inclined tie rod 6 at one end of the outer end frame 3 is connected to the end frame of the adjacent pipe pile, which can balance the unidirectional tension of the steel strand 7 on the pipe pile, prevent the pipe pile from tilting due to excessive unilateral tension, and further improve the overall stability of the pipe pile.

[0059] In summary, this utility model provides a PHC pipe pile structure suitable for flexible support solar-aquaculture integration. Through an auxiliary mechanism, the electric pusher piston rod extends downward, pushing the crossbar to slide and guide along the groove on the inner wall of the PHC pipe pile, ensuring that the crossbar moves smoothly up and down. The crossbar drives the motor, rotating rod, and cross plate to descend synchronously. While rotating, the cross plate applies a downward drilling force, assisting the PHC pipe pile to quickly sink to the target depth under its own weight and external force.
