Description

Technical Field

[0001] The invention belongs to the technical field of bridge construction, and in particular relates to a cofferdam device and method for transporting an extra-large and extra-wide anti-collision casing by a 10,000-ton transport ship. Background Art

[0002] With the rapid development of my country's infrastructure, the construction of large bridges such as those across rivers and across the sea has increased significantly. In order to realize the construction of deep-water foundations and reduce the cost of bridges, Yonglin has been widely used in combination with anti-collision box cofferdams. However, the anti-collision box cofferdam cannot be assembled at the construction site. It needs to be processed and assembled in the factory and then transported to the bridge construction site for overall lowering. For extra-large and extra-wide anti-collision box cofferdams, the width of the transport ship may be smaller than the width of the cofferdam, and it is easy to shift during transportation. This displacement may bring the following hazards:

[0003] (1) Structural damage: Displacement may cause uneven forces to be applied to the cofferdam structure, thus causing deformation. This deformation may cause uneven stress distribution inside the material, exceeding the yield limit of the material, and thus causing cracks. Once cracks appear, they may further expand during subsequent use, reducing the overall strength and waterproof performance of the cofferdam;

[0004] (2) Sealing failure: Cofferdams usually require good sealing performance to prevent water or other liquids from entering the construction area. Displacement may cause damage to sealing materials (such as rubber strips), thereby affecting the sealing effect.

[0005] (3) Delay in construction progress: If the cofferdam cannot be installed correctly due to displacement, additional time and resources may be required for repair and adjustment, which will delay the progress of the entire project.

[0006] (4) Economic losses: Damage and repair work caused by cofferdam displacement will increase project costs. In addition, if the project is delayed due to cofferdam problems, additional economic compensation and fines may be incurred.

[0007] In summary, in order to ensure the safe transportation and installation of the super-large and super-wide anti-collision box cofferdam, appropriate measures should be taken to prevent displacement. This includes using suitable transportation equipment, strengthening the structural design of the cofferdam, and formulating detailed transportation and installation plans. At the same time, the status of the cofferdam should be closely monitored during transportation and installation to promptly detect and deal with any potential problems. In order to prevent the cofferdam from being displaced during transportation, a device and method for transporting super-large and super-wide anti-collision box cofferdams by a 10,000-ton transport ship is designed. Summary of the invention

[0008] In view of this, the present invention aims to overcome the defects in the prior art and proposes a cofferdam device and method for transporting super-large and super-wide anti-collision boxes on a 10,000-ton transport ship.

[0011] In some embodiments of the present invention, the general limit stop frame tooling and the inner limit stop frame tooling have the same structure, both including a first base plate and a first vertical plate arranged on the first base plate, an inclined support plate is connected between the first vertical plate and the first base plate, and a first triangular connecting plate connecting the first vertical plate and the first base plate is vertically arranged on the outer side of the first vertical plate and the first base plate.

[0012] In some embodiments of the present invention, the reinforced limit stop frame tooling includes a second bottom plate and a column arranged at the end of the second bottom plate, and a plurality of second triangular connecting plates are vertically arranged on the outer side of the column.

[0013] In some embodiments of the present invention, the number of the reinforced limit stop frame tooling is 4, which are respectively arranged at the four corners of the steel casing cofferdam to limit the lateral displacement of the steel casing.

[0014] In some embodiments of the present invention, steel plates are used to level the bottom transport vessels of the general limit stop frame tooling, the reinforced limit stop frame tooling and the inner limit stop frame tooling.

[0015] In some embodiments of the present invention, the inner limit stop frame tooling is arranged on both sides of the interior of the anti-collision casing to limit the left and right displacement of the steel casing.

[0016] In some embodiments of the present invention, sleepers are used to pave the space between the general limit stop frame tooling, the reinforced limit stop frame tooling and the inner limit stop frame tooling and the beam section and are tightened with wedges to prevent the steel casing from shifting.

[0017] The present invention also provides a method for transporting an extra-large and extra-wide anti-collision box cofferdam by a 10,000-ton transport ship, the method comprising: after the center of gravity of the anti-collision box is located at the center of the transport ship, a general limit stop frame tooling, a reinforced limit stop frame tooling and an inner limit stop frame tooling are installed between the anti-collision box cofferdam and the plywood, and then sleepers are used to pave the space between the general limit stop frame tooling, the reinforced limit stop frame tooling and the inner limit stop frame and the beam section, and the tools are tightened with wedges to complete the installation for transportation.
