Description

A complete set of automatic piling equipment for bottom discharge at sea using vibratory compaction Technical Field

[0001] This utility model belongs to the technical field of marine engineering construction equipment, specifically relating to a complete set of automatic piling equipment with bottom discharge of marine vibratory compaction. Background Technology

[0002] With the increasing development and utilization of marine resources, offshore engineering projects are on the rise, and offshore pile foundation construction has become an important part of infrastructure construction. Offshore vibro-compaction piling, a commonly used construction method, uses the high-frequency vibration of a vibro-compactor to loosen the soil structure, allowing the pile to be successfully implanted into the underwater soil layer. It is widely used in port construction, offshore wind power foundation construction, and other fields.

[0003] Existing offshore vibro-compactor piling equipment typically uses a vessel to carry the vibro-compactor, which is then raised and lowered using a traction system. During operation, the vibro-compactor directly contacts the underwater soil to achieve the piling function. However, the existing technology has the following problems:

[0004] First, because the vibratory compactor is in direct and frequent contact with the underwater soil, the surface of the vibratory head is prone to significant wear during the piling process, which affects the service life and operational stability of the vibratory compactor. Moreover, repairing or replacing the vibratory head often requires a lot of manpower and time, increasing construction costs.

[0005] Secondly, under the complex geological conditions of the seabed, the vibratory compactor is prone to displacement during the sinking process, which leads to deviations in the construction position of the pile, thereby affecting the quality and structural stability of the entire project, and it is difficult to effectively correct the displacement after it occurs.

[0006] Secondly, when carrying out bottom discharge filling operations, existing equipment usually discharges the filling material directly into the pile hole through the pipeline. However, in actual operation, due to the lack of effective guiding measures, the filling material is prone to flow deviation or accumulation, resulting in uneven filling and affecting the compactness of the pile and the overall bearing capacity. Summary of the Invention

[0007] To address the problems existing in the prior art, the purpose of this utility model is to provide a complete set of automatic piling equipment for bottom discharge of vibratory compaction at sea. This equipment can effectively reduce wear on the vibratory head, prevent the vibratory compactor from deviating during piling, and smoothly realize bottom discharge filling operations, thereby solving the above-mentioned problems in the prior art and improving the efficiency and quality of offshore vibratory compaction piling construction.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A complete set of automatic piling equipment for bottom discharge at sea includes a hull, on which a winch and a mast are installed. A traction rope on the winch passes over the top of the mast, and the tail end of the traction rope is connected to a vibratory compactor and a discharge pipe. The bottom end of the vibratory compactor is connected to a vibratory head cap.

[0010] The vibrator head cap includes a conical head connected to the bottom of the vibrator head, the conical head being used to provide protection for the vibrator head;

[0011] Furthermore, a positioning plate is connected to the bottom of the conical head. The positioning plate is triangular in shape and is used to position the conical head during the piling process.

[0012] A guide component is connected to one side of the conical head. The guide component is connected to the bottom of the feed tube. A wing plate is fixedly connected to one end of the guide component. The wing plate is used to position the guide component.

[0013] Furthermore, the conical head is configured as a frustum shape, and a receiving cavity is provided at the top of the conical head;

[0014] When the conical head is connected to the vibrating head, the bottom end of the vibrating head is inserted into the receiving cavity.

[0015] Furthermore, a connecting hole is provided through the upper end face of the conical head, and the connecting holes are evenly distributed around the central axis of the conical head;

[0016] The connection hole is used to install screws that connect to the vibrator head.

[0017] Furthermore, the top of the positioning plate is provided with a locking groove, the positioning plate is fixedly connected to the conical head, and the conical head is embedded in the locking groove;

[0018] On the center line of both sides of the positioning plate, there are reinforcing strips fixedly connected along its length. The reinforcing strips are used to strengthen the structural strength of the positioning plate.

[0019] Furthermore, the cross-section of the guide component is U-shaped, and a guide plate is inclinedly provided on the inner side of the lower end of the guide component;

[0020] The stones discharged from the discharge pipe are discharged into the pile hole through the guide plate.

[0021] Furthermore, a diagonal brace is fixedly connected to one side of the bottom of the wing plate, and the diagonal brace is located at the bottom of the guide plate.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] In existing offshore vibro-compactor piling operations, the vibratory head is prone to severe wear due to direct contact with the underwater soil, leading to a shortened service life of the vibratory compactor. Frequent replacement of the vibratory head also increases construction costs and the risk of work interruption. To address this issue, this invention incorporates a conical head at the bottom of the vibratory compactor. This conical head, made of highly wear-resistant material and tightly connected to the vibratory head, effectively isolates the vibratory head from direct contact with the soil during piling, significantly reducing wear, extending the overall service life of the vibratory compactor, and lowering maintenance frequency and costs.

[0024] In existing offshore vibratory compaction piling construction, the vibratory compactor is prone to displacement when vibrating and inserting into the underwater soil, causing the pile to deviate and affecting construction accuracy and pile foundation bearing capacity. To address this problem, this utility model sets a positioning plate at the bottom of the conical head and adds reinforcing strips on both sides of the positioning plate. By utilizing the insertion stabilizing effect of the positioning plate and the structural reinforcement effect of the reinforcing strips, the position of the vibratory compactor can be effectively controlled during the piling process, preventing the vibratory compactor from deviating, thereby ensuring the verticality of the pile hole formation and the construction quality.

[0025] In existing bottom-discharge filling processes, stones are directly discharged from the discharge pipe without effective guidance and control, which easily leads to stone dispersion or displacement, resulting in insufficient compaction of the fill material in the pile hole and affecting the bearing capacity of the pile foundation. To address this problem, this utility model introduces a guide component at the bottom of the discharge pipe, with an inclined guide plate inside the guide component. The guide plate smoothly guides the stones to the center area of ​​the pile hole, avoiding uneven stone accumulation, improving the filling quality of the pile body, and thus enhancing the overall bearing capacity of the pile foundation structure.

[0026] In existing operations, due to the complex marine environment, equipment is prone to uneven stress during underwater operations, leading to displacement or swaying, which affects the stability of piling and filling operations. To address this issue, this invention adds a wing plate to one end of the material guide and an additional diagonal brace plate below the wing plate, forming a triangular stable support structure. This structure effectively supports the material guide and related structures, enhances the overall resistance to lateral forces, and thus improves the operational stability and reliability of the equipment in complex marine operating environments.

[0038] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0039] Referring to Figures 1-6, a complete set of automatic piling equipment for bottom discharge at sea using vibratory compaction includes a hull, on which a winch and a mast are installed. The winch is mounted on the deck of the hull and is used to drive the traction rope for winding and unwinding operations via a power output device. The mast is vertically mounted on the hull, and a pulley system is installed at its top to guide the movement path of the traction rope. The traction rope on the winch passes over the top of the mast. The traction rope is made of high-strength, corrosion-resistant material to ensure its service life in harsh marine environments. The tail end of the traction rope is connected to a vibratory compactor and a discharge pipe. The vibratory compactor is used to drive the soil into the seabed to form a pile hole through high-frequency vibration, and the discharge pipe is used to transport stones into the pile hole. The bottom end of the vibratory compactor is connected to a vibratory head cap, which is used to protect the vibratory head during vibratory compaction operations, reduce wear, and extend its service life. The protective cap includes a conical head 1 connected to the bottom of the vibratory head. The conical head 1 is made entirely of metal, which has good wear resistance and impact resistance. The conical head 1 is used to protect the vibratory head and prevent it from being damaged by direct contact with hard soil. A positioning plate 2 is connected to the bottom of the conical head 1. The positioning plate 2 is triangular in shape and is used to position the conical head 1 during piling, thereby preventing the vibratory compactor from shifting during piling. A guide component 3 is connected to one side of the conical head 1. The guide component 3 is connected to the bottom of the feed pipe and is used to guide the stones conveyed by the feed pipe into the pile hole in an orderly manner. A wing plate 4 is fixedly connected to one end of the guide component 3. The wing plate 4 is used to position the guide component 3 and is fixed by inserting it into the soil to prevent the guide component 3 from shaking during operation.

[0040] Referring to Figures 1-3, the conical head 1 is shaped like a frustum and is made of wear-resistant steel with an anti-corrosion treatment to adapt to the high humidity and high salt spray working environment at sea. The top of the conical head 1 has a receiving cavity 11, which is a cylindrical space with reinforcing ribs on the inner wall to improve the stability and pull-out resistance during insertion. When the conical head 1 is connected to the vibrator, the bottom end of the vibrator is inserted into the receiving cavity 11, and the two are fixed by the mating connection, so that the vibrator is subjected to uniform force during operation and the risk of damage is reduced.

[0041] Referring to Figure 3, a connecting hole 12 is provided through the upper end face of the conical head 1. The connecting holes 12 are evenly distributed around the central axis of the conical head 1. Each connecting hole 12 adopts a standard threaded hole design to ensure good mechanical engagement force when installing screws. The connecting holes 12 are used to install screws that connect to the vibratory head. By screwing the screws into the connecting holes 12, the conical head 1 is firmly fixed to the bottom of the vibratory head, ensuring a reliable connection during vibratory compaction operations, preventing loosening, and improving the safety and stability of construction.

[0042] Referring to Figure 4, the top of the positioning plate 2 is provided with a locking groove 22. The locking groove 22 is designed as a groove structure that matches the bottom shape of the conical head 1, ensuring that the conical head 1 can be stably embedded in the locking groove 22 to form a stable connection interface. The positioning plate 2 and the conical head 1 are fixedly connected by welding or high-strength fasteners to ensure the strength and stability of the connection between the two. The conical head 1 is embedded in the locking groove 22, which further enhances the overall anti-displacement capability. On the center line of both sides of the positioning plate 2, a reinforcing strip 21 is fixedly connected along its length. The reinforcing strip 21 is made of corrosion-resistant alloy material and has a rectangular cross-section. The reinforcing strip 21 is used to reinforce the structural strength of the positioning plate 2, improve the bending and shear resistance of the positioning plate 2 in high-frequency vibration environment, and ensure the reliability of the piling operation.

[0043] Referring to Figure 5, the cross-section of the guide component 3 is U-shaped. The U-shaped structure facilitates the concentrated guidance of stones inside the guide component 3 and prevents stones from leaking out during transportation. The guide component 3 is made of high-strength metal material and coated with a wear-resistant coating to extend its service life. A guide plate 31 is inclinedly arranged on the inner side of the lower end of the guide component 3. The guide plate 31 is designed with a smooth curved surface structure, and the inclination angle is optimized according to the flow characteristics of the stones to improve the stone introduction efficiency. The stones discharged by the discharge pipe are discharged into the pile hole through the guide plate 31. The presence of the guide plate 31 effectively guides the stones to the central area of ​​the pile hole, avoids the accumulation of stones at the edge of the pile hole, improves the filling density, and thus improves the bearing capacity of the pile foundation.

[0044] Referring to Figure 6, a diagonal brace 41 is fixedly connected to one side of the bottom of the wing plate 4. The diagonal brace 41 is made of high-strength material and has a reinforcing rib structure to improve its load-bearing capacity, ensuring sufficient support strength when inserted into the soil. The diagonal brace 41 is set at the bottom of the guide plate 31. The diagonal brace 41, the wing plate 4, and the guide plate 3 form a stable triangular support structure, further enhancing the deformation resistance of the entire equipment during the piling and filling process, thereby ensuring the overall stability of the equipment in the complex marine operating environment.
