Embodiment Construction

[0026] Such as Figure 1 to Figure 7 As shown, the sand bag stacking construction device for the treatment of submarine suspended pipelines includes: floating body 12, lifting lug 1, container bag 2, lifting ring 3, top pin hole 4, top pin 5, sand bag bin 6, sand bag 7, concave Groove 8, bearing bin 9, bearing bin pin hole 10, bearing bin pin 11.

[0027] The main body of the floating body 12 is a cuboid made of solid buoyant material with strong pressure resistance; the solid buoyant material can be buoyant materials such as chemical foam composite material, microsphere foam composite material or light synthetic composite material.

[0028] Four lifting lugs 1 are arranged on the top of the floating body 12; the four lifting lugs 1 are respectively located on the four corners of the top surface, and are symmetrical to the two center lines of the rectangle on the top surface. The lifting lug 1 is used to connect the hook of the land crane, thereby hoisting the sandbag stackin...

Abstract

The invention belongs to the field of ocean engineering, and in particular, relates to a sand bag stacking construction device and a construction method for seabed suspended pipeline treatment, whichis used for treating the submarine suspended pipeline. The sand bag stacking construction device for treating the seabed suspended pipeline comprises a floating body, a lifting lug, a container bag, hanging ring, a top pin hole, a top pin, a sand bag bin, a sand bag, a groove, a weight bearing bin, a weight bearing bin pin hole and a weight bearing bin pin; the floating body main body is a cuboidand is made of a solid buoyancy material; four corners of the top of the floating body is provided with up-lifting lugs, and the center of the bottom of the floating body is provided with an arch-shaped groove; the center of the top of the floating body is provided with a semi-cylindrical weight bearing bin, and the center of the bottom of the floating body is provided with a weight bearing bin pin hole; the two sides of the weight bearing bin are provided with two sand bag bins for placing container bags; four corners of the sand bag bin are provided with top pin holes for fixedly connectingthe top pins of the lifting ring; by using the device, the underwater landing place of the sand bag can be accurately located, the sand bag can be neatly stacked, and the problem of the submarine pipeline suspension can be accurately and efficiently addressed.

Description

technical field [0001] The invention belongs to the field of marine engineering, and in particular relates to a construction device for stacking sandbags for the treatment of suspended submarine pipelines, which is used for the treatment of suspended submarine pipelines. Background technique [0002] Submarine pipelines are located in a complex marine environment, and they need to withstand loads such as internal pressure, gravity, and temperature during service. Therefore, the suspended position of submarine pipelines is very prone to suspension. How to control the suspension of submarine pipelines has attracted more and more attention. At present, the sandbag method is commonly used in engineering to control the suspension of submarine pipelines, which has the advantages of simple operation, economical and effective; however, the construction method of the sandbag method is very backward, and the sand is usually packed into bags manually on land, and then through constructi...
