Embodiment 1

[0024] refer to Figure 1-3 , is a gravel tank of a prefabricated offshore fixed platform, used to store gravel 14 under the bottom plate 2 of the platform main body 1, which is surrounded by the bottom plate 2 and two arched decks 3, wherein the bottom plate 2 is respectively The arched deck supports 4 are set, and the ends of the arched decks 3 are respectively connected to the arched deck supports 4, and each arched deck 3 is in an upward arch shape, and is composed of block stones 5 and keystones 6 It is constructed by laying bricks and stones, and a keystone pulling and pressing device 7 is provided between the keystone 6 and the bottom plate 2 . A plurality of gravel replenishment holes 11 are provided on the bottom plate 2, and gravel can be replenished into the gravel chamber 15, and gravel can also be replenished to the filling surface after release. Prestressed tension beams 8 are arranged between two adjacent arched deck supports 4 , thereby forming a frame structu...

Embodiment 2

[0028] refer to Figure 4-5 , is another prefabricated gravel tank of a fixed offshore platform, which is used to store gravel 14 under the bottom plate 2 of the platform main body 1, which is surrounded by the bottom plate 2 and three arched decks 3, wherein the bottom plate 2 Arched deck supports 4 are provided, and the ends of the arched decks 3 are respectively connected to two adjacent arched deck supports 4. 5 and the keystone 6 are built together, and the keystone tension and compression device 7 is provided between the keystone 6 and the bottom plate 2. A plurality of gravel replenishment holes 11 are provided on the bottom plate 2, and gravel can be replenished into the gravel chamber 15, and gravel can also be replenished to the filling surface after release. The keystone 6 is tensioned upwards by the keystone pulling and pressing device 7 , so that both ends of the arched deck 3 press the arched deck support 4 . In addition, related restraint devices can be set be...

Embodiment 3

[0031] refer to Image 6 , is another prefabricated gravel tank of a fixed offshore platform, which is used to store gravel 14 under the bottom plate 2 of the platform main body 1, which is surrounded by the bottom plate 2 and a double-arched arched deck 3, wherein the bottom plate 2 is provided with an arched deck support 4 and a movable beam 12, and a beam tensioning and compressing device 13 is provided between the movable beam 12 and the bottom plate 2, and the movable beam 12 can be suspended below the bottom 2, and the arched deck 3 The ends are respectively connected to the arched deck support 4 and the movable beam 12, and the double arch is formed by the movable beam 12 and the two arched decks 3, and the tensile force is applied to the movable beam 12 through the beam tension and compression device 13 to ensure that the arch The structure of the arched deck is stable, and the bearing capacity is improved. At the same time, moving the movable beam 12 can also cause th...

Abstract

The invention discloses a gravel bin of a prefabricated fixed offshore platform. The gravel bin is defined by a base plate and at least one arched deck, wherein arched deck supporting parts connected with the ends of the arched decks are arranged below the base plate, each arched deck is formed by laying dimension stone and capstone, and a capstone tensioning and compressing device is arranged between the capstone and the base plate. The gravel bin has the advantages that gravel in the bin can be released fast, the releasing range is wide and uniform, and the filling effect is better.

Description

technical field [0001] The invention relates to a prefabricated offshore fixed platform, in particular to a gravel release technology when the fixed platform sits on the bottom. Background technique [0002] With the continuous development and utilization of the ocean, operators and equipment need to stay in the open sea or near islands and reefs for a long time, so it is necessary to build a fixed operating platform or supply platform. The earliest platform construction method is to directly transport various building materials required for platform construction to the site by ship, directly excavate and treat the foundation on site, and then perform concrete pouring or steel structure setting on the foundation. This construction method will cause irreversible damage to the marine environment of the construction site, and the construction operation is greatly affected by the weather conditions, the operation is difficult, and the supply is difficult and the cost is high. T...
