Some sites have large waves, some sites have large swells, and some sites have large wind power. In the design process of an ore wharf, considering the economy of ocean-going ship ore transportation, the design ship type of the ore wharf is usually 200-300 thousand tons, and if the water depth condition of the port area is good, the deadweight tonnage of the design ship type will be larger, and the overall structure of the wharf will also increase the stress, and the beams, plates and surface layers of the upper structure of the wharf will also increase.

[0021] In order to further explain the technical means and effects taken by the present application to achieve the predetermined purposes, the specific embodiments, structures, features and effects according to the present application are described in detail below in combination with the drawings and preferred embodiments.

[0022] Figure 1 is a schematic view of a ship berthing member of a fabricated jacket ore wharf according to an embodiment of the present application. As shown in Figure 1 , the ship berthing member 1 is supported on the jacket pile 2. Specifically, the ship berthing member 1 comprises a horizontal annular stiffener 4, a fender support 11 and a rubber fender 10.

[0023] As shown in Figure 1 , the rubber fender 4 is fixedly connected with the horizontal annular stiffener 4 through the fender support 11; the horizontal annular stiffener 4 is arranged between the fender support 11 and the jacket pile 2.

[0024] Figure 2 is a top view of a ship berthing member of a fabricated jacket ore wharf according to an embodiment of the present application. As shown in Figure 2 , a horizontal crossbar 3 is arranged on the opposite side of the horizontal annular stiffener 4 away from the fender support 11; the vertical elevation center of the rubber fender 10 and the geometric center of the horizontal crossbar 3 are on the same horizontal line; the outer elevation of the rubber fender 10 is in horizontal contact with the straight line segment of the ore ship.

[0025] As shown in Figure 1As shown, in this embodiment of the invention, there are three horizontal annular stiffening ribs 4; three horizontal annular stiffening ribs 4 are arranged in sequence in the vertical direction between the fender support 11 and the guide frame support column 2; wherein, the two horizontal annular stiffening ribs located at the top and bottom are symmetrically arranged on both sides of the horizontal annular stiffening rib in the middle position; the center of the horizontal annular stiffening rib in the middle position is arranged on the same horizontal line as the centroid of the horizontal crossbar 3.

[0026] In this embodiment of the invention, the horizontal annular stiffening rib 4 ensures that the berthing force of the ship mooring on the rubber fender 10 is transmitted to the jacket support column 2 in a more reasonable manner, avoiding excessive local stress concentration. The arrangement of the center of the middle horizontal annular stiffening rib and the centroid of the horizontal crossbar 3 on a straight line maximizes the efficiency of the horizontal crossbar 3 in resisting the horizontal berthing force transmitted from the rubber fender 10, avoids the generation of eccentric bending moment, and thus maximizes the compressive strength but not bending strength of the member.

[0027] Figure 3 This is a side view of another assembled jacket structure ore wharf berthing component provided according to an embodiment of the present invention. Figure 3 As shown, the fender support 11 includes: a vertical rectangular stiffening rib 5, a horizontal bar 6, a vertical diagonal brace 7, a fixed end 8, and a cross-shaped stiffening rib 9.

[0028] Specifically, such as Figure 3 As shown, the vertical rectangular stiffening ribs 5 and the horizontal annular stiffening ribs 4 are perpendicularly arranged on the longitudinal and transverse symmetrical planes of the jacket support column 2.

[0029] The fender support 11 consists of three layers with multiple horizontal bars 6 arranged in the horizontal direction. The direction of the horizontal bars 6 is parallel to the horizontal bars 3. The extended axis of the horizontal bar in the middle of each layer passes through the center of the horizontal annular stiffening rib 4, and the horizontal bars 6 on both sides of each layer are tangent to the circumference of the horizontal annular stiffening rib 4. The vertical diagonal braces 7 are diagonally connected to the horizontal bars of the three layers respectively.

[0030] Preferably, such as Figure 3 As shown, the fender support 11 has nine horizontal bars 6 arranged in three layers, with each layer consisting of three bars on the left, middle, and right. The middle bar is parallel to the horizontal bar 3, and its extended axis passes through the center of the horizontal annular stiffening rib 4 fixed to the jacket support column 2, and is perpendicular to the axis of the jacket support column 2. The left and right bars are symmetrically arranged on both sides of the middle bar and are tangent to the circumference of the horizontal annular stiffening rib 4. Three pairs of vertical diagonal braces 7 connect the nine horizontal bars 6 in three vertical planes to enhance their rigidity and stability in the vertical plane.

[0031] like Figure 3As shown, the vertical diagonal braces 7 and the horizontal bars 6 are fixedly connected with the fixed end 8, and a cross-shaped stiffening rib 9 is arranged inside the fixed end 8; and the rubber fender 10 is fixed on the fixed end 8 in the horizontal direction.

[0032] Figure 4 、 Figure 5 It is a side elevation view and front elevation view of an assembled jacket ore wharf berthing member according to the embodiment of the present application. Figure 4 As shown, the center position of the cross-shaped stiffening rib 9 is on the same horizontal line as the centroid of the horizontal bar 3.

[0033] Optionally, in the embodiment of the present application, the vertical two ends of the rubber fender 10 are chamfered and curved for smooth processing.

[0034] In the embodiment of the present application, the three pairs of vertical diagonal braces 7 and the nine horizontal bars 6 are connected with the berthing member support fixed end 8, and the cross-shaped stiffening rib 9 is arranged inside the fixed end 8 to enhance the in-plane stiffness of the fixed end 8. The rubber fender 10 is fixed on the fixed end 8 in the horizontal direction, and the outer elevation of the rubber fender 10 is in horizontal contact with the straight line segment of the ore ship. In order to make the outer elevation of the rubber fender 10 more reasonable in stress, the vertical two ends of the rubber fender 10 are chamfered and curved for smooth processing to prevent stress concentration at the ends and shorten the overall service life of the rubber fender 10. The rubber fender 10 connected with the fixed end 8 can be replaced when it reaches its service life.

[0035] In the embodiment of the present application, the design height and number of the berthing member 1 are determined by the ship type, draft, and straight line segment range of the ore ship. The vertical elevation centroid of the rubber fender 10 is always on the same horizontal line as the geometric centroid of the jacket pile cap horizontal bar 3. The berthing member 1 can be symmetrically arranged on the two jacket pile cap columns 2 of the jacket pile cap to make the stress more reasonable.

[0036] Figure 6 It is a front elevation view of the installation position of an assembled jacket ore wharf berthing member according to the embodiment of the present application.

[0037] Specifically, as shown in the figure, Figure 5 The berthing member 1 is symmetrically arranged on the two jacket pile cap columns 2 of the jacket pile cap, and the horizontal bar 3 is arranged between the two berthing members.

[0038] In the embodiment of the present application, the berthing member 1 is pre-installed on the jacket pile cap on land to reduce the installation time on the sea.

[0039] From the above description, the application provides an assembled jacket wharf ore dock berthing member, the berthing member is prefabricated in a land factory in advance and installed on the jacket pile cap, the integration design level and construction efficiency of the jacket pile cap and the berthing member are improved, and the installation operation time of the berthing member on the sea is reduced; the connection mode of the horizontal annular stiffening rib combined vertical rectangular stiffening rib and the jacket pile cap column meets the functional requirement of the berthing member and optimizes the overall stress of the jacket pile cap.
