Description

Technical Field

[0001] This utility model belongs to the field of marine engineering technology, specifically relating to a high-strength corrosion-resistant steel pile for marine engineering. Background Technology

[0002] Steel piles, as supporting components in marine infrastructure, are made of steel. During use, the high salt concentration of seawater makes them highly conductive, which makes them prone to corrosion. In addition, waves, tides, and currents generate low-frequency reciprocating stress and impacts on the metal components, further damaging the steel piles and causing them to corrode and break down quickly, thus increasing the cost of use.

[0003] Currently, traditional steel piles mainly use electrochemical protection in the seawater immersion zone and coating protection in the atmospheric zone. However, in the splash zone between the seawater immersion zone and the atmospheric zone, the coating is prone to blistering and peeling due to the frequent impact of seawater. Furthermore, since this area is not covered by seawater, an effective current loop cannot be formed, rendering the electrochemical protection method ineffective.

[0004] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0005] The purpose of this invention is to overcome the problems of weak corrosion resistance and short service life of traditional steel piles in the splash zone, and to provide a high-strength corrosion-resistant steel pile for marine engineering.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-strength corrosion-resistant steel pile for marine engineering includes: a pair of rigid clamping plates, a pair of flexible clamping plates, and a hoop. The pair of rigid clamping plates encircle the splash zone of the pile body side by side. The outer edges of the rigid clamping plates have radially protruding composite columns, and adjacent composite columns are horizontally opposite each other. The inner side of the rigid clamping plates is covered with a rubber pad, and the edge of the rubber pad extends radially with an ear pad, which is located between adjacent composite columns. The pair of flexible clamping plates overlap each other to encircle the outside of the two rigid clamping plates. The overlapping part of the two flexible clamping plates is connected as one unit by a set screw. The head of the set screw passes through the overlapping part of the two flexible clamping plates and the middle of the rigid clamping plate in sequence, and then presses against the rubber pad. The hoop is interference-fitted onto the outside of the two adjacent composite columns to tighten the two adjacent composite columns and press the flexible clamping plates and the rigid clamping plates together through the hoop.

[0008] In the high-strength corrosion-resistant steel piles for marine engineering described above, preferably, the flexible retaining plate has a positioning hole in the middle of its surface, allowing two adjacent composite columns to pass through simultaneously.

[0009] Preferably, the tail of the set screw is upset to press the overlapping part of the two flexible clamping plates together.

[0010] Preferably, the upper and lower ends of the rigid clamping plate both extend radially with limiting plates;

[0011] The flexible retaining plate is positioned exactly between the two limiting plates.

[0012] Preferably, the surface of the rigid plate is provided with through holes.

[0013] Preferably, the inner side of the flexible plate is provided with a protrusion corresponding to the through hole.

[0014] Preferably, the protrusion presses against the rubber pad after passing through the through hole.

[0015] Preferably, the set screw is threadedly connected to the rigid retaining plate.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0030] This embodiment aims to provide a high-strength corrosion-resistant steel pile for marine engineering. Its main function is to significantly enhance the corrosion resistance of the steel pile in the splash zone, resulting in strong corrosion resistance and a long service life.

[0031] Reference Figure 1-3 and Figure 6-8It includes: a pair of rigid clamping plates 2, a pair of flexible clamping plates 6, and a hoop 8. The two rigid clamping plates 2 are wrapped around the splash zone of the pile body 1 side by side, and their upper and lower ends are flush. Multiple combined columns 3 are radially protruding from the outer side of the rigid clamping plate 2, and the two adjacent combined columns 3 are horizontally opposite each other. A rubber pad 4 is fixedly adhered to the inner side of the rigid clamping plate 2 to provide a certain shrinkage space between the two rigid clamping plates 2. The rubber pad 4 completely covers the inner side of the rigid clamping plate 2. The pad edge of the rubber pad 4 extends radially with an ear pad 5. The ear pad 5 is located between the two adjacent combined columns 3, and the upper and lower edges of the ear pad 5 are flush with the upper and lower parts of the combined column 3 so that the hoop 8 can be interference fitted on the outside of the two adjacent combined columns 3.

[0032] Reference Figure 1-5 The upper and lower ends of the rigid clamping plate 2 are both radially extended with limiting plates 10. The opposite sides of the two flexible clamping plates 6 overlap each other to encircle the outside of the two rigid clamping plates 2. The flexible clamping plate 6 is exactly between the two limiting plates 10. That is, the vertical length of the flexible clamping plate 6 matches the distance between the two limiting plates 10. The overlapping part of the two flexible clamping plates 6 is connected as one unit by a set screw 7. The head of the set screw 7 passes through the overlapping part of the two flexible clamping plates 6 and the middle of the rigid clamping plate 2 in sequence and then presses against the rubber pad 4. Multiple set screws 7 can be evenly arranged in the vertical direction to ensure the stability of the overall structure. The set screw 7 is threaded to the rigid clamping plate 2. By rotating the set screw 7, the pressure generated by its head on the rubber pad 4 can be increased. Correspondingly, the tail of the set screw 7 is upset. As the pressure of the head of the set screw 7 on the rubber pad 4 increases, the friction between the rubber pad 4 and the steel pile increases and becomes more stable. At the same time, the pressing force of the tail of the set screw 7 on the overlapping part of the two flexible clamping plates 6 is stronger, which can also increase the firmness of the connection between the two flexible clamping plates 6.

[0033] Reference Figure 3-8 The flexible retaining plate 6 has a positioning hole 9 in the middle of its surface, which allows two adjacent composite columns 3 to pass through simultaneously, so as to ensure that the flexible retaining plate 6 and the outer wall of the rigid retaining plate 2 are completely fitted together. The hoop 8 is interference-fitted onto the outside of the two adjacent composite columns 3, which is to tighten the two adjacent composite columns 3. During this process, the two adjacent and horizontally opposite composite columns 3 will gradually squeeze the ear pads 5 between them, while the hoop 8 will gradually press the flexible retaining plate 6 and the rigid retaining plate 2 together. This not only tightens the two rigid retaining plates 2 with the steel pile, but also enhances the firmness of the assembly of the flexible retaining plate 6 and the rigid retaining plate 2.

[0034] In this embodiment, the surface of the rigid retaining plate 2 is provided with through holes 11, and the inner side of the flexible retaining plate 6 is provided with protrusions 12 corresponding to the through holes 11. When the flexible retaining plate 6 is covered on the outside of the rigid retaining plate 2, the protrusions 12 will pass through the corresponding through holes 11 and press against the rubber pad 4. The protrusions 12 can further enhance the firmness between the flexible retaining plate 6 and the rigid retaining plate 2, and at the same time, further enhance the friction between the rubber pad 4 and the steel pile wall, greatly enhancing its anti-slip ability on the steel pile, so as to prevent the entire corrosion-resistant layer from shifting after long-term use and failing to effectively resist corrosion in the splash zone of the steel pile.

[0035] During actual installation, first, two rigid clamping plates 2 are wrapped around the splashing area of ​​the steel pile. Then, two flexible clamping plates 6 are placed on opposite sides, overlapping and wrapping around the outside of the two rigid clamping plates 2, with the overlapping part of the two flexible clamping plates 6 corresponding to the middle of the rigid clamping plate 2. Ensure that all the protrusions 12 on the inner side of the flexible clamping plate 6 are inserted into the through holes 11 on the rigid clamping plate 2. Then, the overlapping part of the flexible clamping plate 6 is fixed to the middle of the rigid clamping plate 2 using the set screw 7. During the fixing process, the two flexible clamping plates 6 can be pre-fixed with a work strap to facilitate the installation of the set screw 7.

[0036] This embodiment can effectively protect the splash zone of steel piles, greatly enhance the corrosion resistance of steel piles, significantly extend their service life, reduce maintenance frequency, and provide great convenience for marine engineering.

[0037] It is understood that the above description is merely exemplary and the embodiments of this application do not limit the scope of the application.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
