Description

Technical Field

[0001] This invention belongs to the field of offshore foundation engineering, specifically designing a detachable buckling-resistant support device and its installation method. Background Technology

[0002] Currently, with the development of construction technology, especially the improvement of the installation capabilities of large ship machinery, steel cylinder cofferdam structures are being used more and more in nearshore foundation engineering fields such as nearshore cofferdam projects, in order to shorten the construction period under complex sea conditions and improve construction quality and safety.

[0003] Steel cylinder cofferdams, as a new type of nearshore engineering cofferdam technology, are gradually emerging. They are not only highly efficient in construction, but also meet the engineering requirements such as structural stability in various complex environments. In steel cylinder cofferdams, after the steel cylinders are constructed, the space between the steel cylinders is connected by inner and outer steel connecting plates to form an integral force-bearing system. However, in order to accommodate the deviation of the main structure, the steel connecting plates usually need to have a certain degree of flexibility. Generally, it is required that coarse-particle filler be backfilled in the space between the inner and outer steel connecting plates as soon as possible after construction to ensure the formation of filling rigidity.

[0004] Due to constraints in construction organization and space, backfilling is often delayed. At this time, the flexible steel plate is under extreme stress under the action of waves and is easily deformed. If the wave exceeds the predicted wave height, fatigue damage or even tearing of the steel plate may occur, causing losses to the project, affecting the construction period, and on-site repair is also extremely difficult. Summary of the Invention

[0005] In order to overcome the problems of weak wave resistance, easy buckling deformation and damage of steel connecting plates after installation in the prior art, as well as the problems of large concentrated force at the end of the steel connecting plate and low safety and reliability of conventional locking and end plates, this invention designs a detachable anti-buckling support device and installation method.

[0067] Example 2

[0068] This embodiment is based on Embodiment 1 and mainly introduces the specific parameters and connection method of a detachable buckling-resistance support device, such as... Figures 3-5 As shown;

[0069] The support device 1 includes a support plate 101, a support reinforcing rib web 102, a support reinforcing rib arc-shaped wing plate 103, a pad 104, a bolt 105, a spring 106, and an anchor plate 107. The pad 104 has a round hole in the middle to ensure the installation clearance of the bolt 105. The function of the support device 1 is to prevent the steel connecting plate 2 from buckling and deforming. The support plate 101 has a wall thickness of 16mm, a height of 1m, and its length and radius match the position and dimensional parameters of the main structure of the steel cylinder 4 and the steel connecting plate 2. The support reinforcing rib web 102 has a cross-section of 14×150mm steel plate, and the support reinforcing rib arc-shaped wing plate 103 has a 14×120mm arc-shaped steel plate. The pad 104 has a 12×60×60mm steel plate with a round hole in the middle with a diameter of 26mm. The anchor plate 107 has a 16×150×900mm steel plate. The bolt 105 is an M22 bolt.

[0070] The steel connecting plate 2 includes a steel connecting plate surface 201, a steel connecting plate reinforcing rib web 202, a steel connecting plate reinforcing rib arc-shaped wing 203, an end reinforcing plate 204, and a vertical end plate 205. The steel connecting plate surface 201 is made of flat steel plate bent into an arc shape. The radius of the arc is determined according to the position of the lock opening and is radially tangent to the main structure. The radius is generally less than 6 mm, and the wall thickness is 16 mm. The cross-sectional dimensions of the steel connecting plate reinforcing rib web 202 are 14×150 mm, and the cross-sectional dimensions of the steel connecting plate reinforcing rib arc-shaped wing 203 are 14×120 mm arc-shaped cross-sections. The cross-sectional dimensions of the end reinforcing plate 204 are 14×150 mm. The cross-sectional dimensions of the vertical end plate 205 are 18×110 mm.

[0071] The supporting reinforcing rib web 102 and the supporting reinforcing rib arc-shaped wing plate 103 are welded together to form an integral T-shaped reinforcing structure. The outward convexity of the supporting reinforcing rib arc-shaped wing plate 103 is the same as the arc of the steel connecting plate. Since only the web is welded, in order to improve construction accuracy and reduce welding difficulty, welding can generally be carried out when the supporting plate surface 101 is in a flat state, and then the supporting plate surface 101 is bent into a set shape.

[0072] The steel connecting plate reinforcing rib web 202 and the steel connecting plate reinforcing rib arc-shaped wing plate 203 are welded together to form an integral T-shaped reinforcing structure. The concave arc of the steel connecting plate reinforcing rib arc-shaped wing plate 203 is the same as the arc of the support plate surface 101. Since only the web is welded, in order to improve construction accuracy and reduce welding difficulty, welding can generally be done when the steel connecting plate is in a flat state, and then the steel connecting plate is bent into the set shape.

[0073] The double T-shaped locking port 3 is composed of two sets of T-shaped steel web plates 301, T-shaped steel wing plates 302, and locking port reinforcing ribs 303. The locking port reinforcing ribs 303 are set on both sides along the height with a spacing of 300mm, and are welded to the T-shaped steel web plates 301, T-shaped steel wing plates 302, and the main steel cylinder structure 4. The T-shaped steel web plates 301 are made of 20×165mm steel plates, the T-shaped steel wing plates 302 are made of 25×155mm steel plates, and the locking port reinforcing ribs 303 are made of 20×155×70 / 90mm steel plates.

[0074] The support device 1 is installed by insertion from top to bottom and is assembled and connected to the steel connecting plate 2 by bolts 105, which can be easily disassembled. Before the support device 1 is installed, the construction party needs to customize a special hanger to ensure that the support device 1 is subjected to uniform force during the hoisting process and to avoid deformation.

[0075] The supporting reinforcing rib arc-shaped wing plate 103 can contact the steel connecting plate 2, and the steel connecting plate reinforcing rib arc-shaped wing plate 203 can contact the supporting plate surface 101, both forming contact pressure and producing an overall effect; during the processing of the steel connecting plate, it is necessary to ensure the consistency of the deviation of the components, or to reserve a certain positive deviation to ensure that contact can be formed.

[0076] The anchor plate 107 is arc-shaped. After the bolts 105 are tightened and installed, the anchor plate 107 can be tightly attached to the arc-shaped wing plate 203 of the steel connecting plate reinforcing rib. Before installation, due to the spring 106 and the pad 104, there is a certain gap between the anchor plate 107 and the support plate surface 101, which facilitates installation. Before installation, the spring 106 and the gap status need to be checked to ensure that the anchor plate 107 is in a vertical state. The support device 1 should be placed vertically during storage to avoid deformation. A special storage rack can be set up.

[0077] The end of the steel connecting plate adopts a double-layer structure, and an end reinforcing plate 204 is added, which is welded to the steel connecting plate 2 and the vertical end plate 205. The welding adopts bevel welding and fillet welding respectively, and all the welds of the reinforcing plate need to be inspected.

[0078] This invention provides a detachable anti-buckling support device. The steel connecting plate adopts a double-layer structure and is connected to the support device, which makes the steel connecting plate strong in wave resistance and buckling deformation resistance after installation. At the same time, it improves the ability of the steel connecting plate end to withstand concentrated force, thereby increasing the safety and reliability of conventional locking and end plates.

[0079] Example 3

[0080] This embodiment is based on Embodiment 1 and mainly introduces the installation steps of a detachable buckling-resistance support device, specifically including the following steps:

[0081] Step S1: Prefabricate the main steel cylinder structure 4;

[0082] Step S2: Fix and weld double T-shaped locking seams 3 on both sides of the main steel cylinder structure 4 according to the set positions;

[0083] Step S3: After the main steel cylinder structure 4 is installed in place at the construction site, the steel connecting plate 2 is installed downwards on both sides through the double T-shaped locking holes 3 and is integrally connected with the main steel cylinder structure 4.

[0084] Step S4: The support device 1 is inserted into the upper part of the steel connecting plate 2 from top to bottom and is assembled and connected by bolts 105.

[0085] This invention discloses a detachable anti-buckling support device and installation method. During installation, it can be quickly installed in case the backfill supply is not timely or the wind and waves exceed expectations, providing temporary reinforcement and support for the steel plate, preventing buckling deformation, fatigue damage, or even tearing of the steel plate. When environmental conditions improve, the support device can be removed to ensure the safety and reliability of the steel plate.

[0086] The above description is merely a preferred embodiment of the present invention and does not limit the scope of protection of the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any changes, modifications, substitutions, integrations, and parameter alterations to these embodiments within the spirit and principles of the present invention, achieved through conventional substitutions or by achieving the same function without departing from the principles and spirit of the present invention, fall within the scope of protection of the present invention.
