Embodiment Construction

[0030] refer to figure 1 with figure 2 As shown, a large-scale steel cylinder cofferdam structure of the present invention includes a cylinder body 1 of steel structure, and the thickness of the cylinder body 1 is 16-25mm; on the inner wall of the cylinder body 1, there are several vertical reinforcing ribs distributed along the circumferential interval 2. The vertical reinforcing ribs 2 can satisfy the vertical force transmission of the entire cylinder body 1 during the vibration sinking and uplifting period; on the inner wall of the exposed part of the cylinder body 1, a number of transverse reinforcement structures 3 are arranged at intervals along the axial direction; The inner diameter of the body 1 is 15-30 meters. The top elevation of the cylinder body 1 shall be determined according to the sea level and waves in the open sea, and the bottom elevation shall be determined according to the stability of the structure under the corresponding soil layer and the water-stop r...

Abstract

The invention discloses a large-scale steel cylinder cofferdam structure, belonging to the technical field of cofferdam structures. The large-scale steel cylinder cofferdam structure is characterized by comprising a steel-structure cylinder body, wherein a plurality of vertical reinforcing ribs are distributed along the circumferential direction of the inner wall of the cylinder body at intervals; a plurality of transverse reinforcing structures are arranged on the inner wall of the exposed part of the cylinder body along the axial direction at intervals; the inner diameter of the cylinder is 15-30 meters. The large-scale steel cylinder cofferdam structure is reasonable in structure and high in construction efficiency, can be circularly used and is used for constructing offshore engineering structures such as bridge bearing platforms.

Description

[0001] technical field [0002] The invention relates to a cofferdam structure, and more specifically relates to a large steel cylindrical cofferdam structure used for the construction of marine engineering structures such as bridge caps. Background technique [0003] In order to create a small-scale dry construction environment in the open sea, construction cofferdams supported by steel sheet piles (or steel pipe piles) or double-walled steel cofferdams composed of multiple steel plate units are often used. For the construction cofferdam supported by steel sheet piles (or steel pipe piles), multiple steel sheet piles need to be installed and the support structure should be installed step by step according to the excavation depth of the foundation pit, and the stability and water-stop requirements can be met by embedding and supporting; double-wall The steel cofferdam needs to splice steel plate units one by one, and then pour concrete for the back cover to meet the stab...
