Problems solved by technology

When the subsea foundation soil is soft and the water depth is slightly larger, the riprap roadbed has a heavy weight, and the soft soil foundation has a lower bearing capacity, so a large number of subgrade stones will sink into the soft seabed soil or squeeze it away , making the cross-section of the subgrade larger, and the project cost will be greatly increased

Embodiment Construction

[0014] An example of an embodiment of the present invention is as follows: a kind of horizontal cylinder offshore subgrade structure as shown in Fig. 1 and Fig. The stone material 4 and the pavement layer 5 are composed. The bottom reinforced concrete cylinder with a diameter of 7.5m, a wall thickness of 0.3m, and a length of 12m is perpendicular to the road axis and lies on the seabed foundation. The upper side of the cylindrical body is 8m long, and a 0.3m thick right-angled concrete wing wall 6 is provided on the outer side of the lower semicircle at the two ends of the cylindrical body. A small reinforced concrete cylinder with a diameter of 1.8m, a wall thickness of 0.15m and a length of 7m is placed on the upper part between two adjacent bottom cylinders. Set side walls on both sides of the bottom cylinder and the upper part of the small cylinder. The thickness of the side walls is 0.4m. The height from the upper top of the bottom cylinder to the top of the side walls i...

Abstract

The invention discloses a roadbed structure at-sea. It is the reinforced concrete cylinder body arranging layer laying on the roadbed in submarine and the axes plumbing to the axes of road at-sea. Small diameter reinforced concrete cylinder body group is filling and leveling up on the cylinder body arranging layer. Side wall is set on the two ends of the cylinder body arranging layer and the small cylinder body group, and samdstone is filled between the two side walls, and the road surface on the sandstone. The cylinder body arranging layer is isosceles trapezoid that the bottom length is longer than that of the top. The two ends of the bottom reinforced concrete cylinder body are set wing walls. The roadbed structure has lower deadweight and has high adaptability to the wave and tide.

Description

technical field [0001] The invention relates to an offshore roadbed structure with a horizontal cylinder. It belongs to the architectural structure in the field of offshore and port engineering. Background technique [0002] At present, in offshore and port engineering, building roads on the sea includes three types of structures, one is a viaduct form, the other is a tunnel form, and the other is a form of laying and filling roadbeds from seabed foundations. In a specific project, it is necessary to determine the specific structural form according to the use requirements, geological conditions, surrounding environmental conditions, and project cost factors. If adopting the form of laying and filling roadbed from the seabed foundation to build the sea road, it is usually to fill a solid roadbed foundation with sand and gravel from the seabed foundation, and then build the road on it. In the marine environment, in order to ensure the stability of th...
