Net cover structure of engineering air bag

Abstract

The invention discloses a net cover structure of an engineering air bag. The movable net cover structure is formed by longitudinal hanging bands 2 and transverse hanging bands 5. The transverse hanging bands 5 penetrate through inner holes of rubber pipes 4 and fixing holes in the longitudinal hanging bands 2 to realize even distribution and limiting, on the circumference of a bag body, of the longitudinal hanging bands 2 in the circumferential direction. The two ends, located on the air bag 1, of each longitudinal hanging band 2 are provided with hanging lugs, the other end of each longitudinal hanging band 2 is located in the middle of the bag body and longitudinal tensioning of the longitudinal hanging bands 2 is realized by winding rope 5 in a crossed mode. The net cover structure can be fixedly bonded on an air bag with any diameter, and multi-point bearing binding of lateral floating force when the air bag is placed horizontally and single-point bearing binding of axial floating force when the air bag is placed longitudinally are realized. The net cover structure can be installed, disassembled and transported on the air bag easily, and the problem that floating-assisting binding cannot be conducted on large-diameter air bags is solved. The net cover structure is reasonable in stress, improves the construction safety, is high in reutilization rate, reduces construction investment and has wide application prospects in the fields such as ocean engineering construction and boat fishing.

Description

technical field [0001] The invention relates to the technical field of high-strength inflatable rubber airbags for engineering, in particular to the field of engineering airbags that have higher requirements on bearing capacity and pressure. Background technique [0002] In engineering fields such as marine engineering construction and ship salvage, it is very important to use the volume of displaced water to obtain buoyancy. In order to obtain greater buoyancy, inflatable rubber airbags are gradually being used. Compared with steel buoys, the advantages are: It can obtain great buoyancy with low economic investment, and can complete underwater installation of steel components, ship salvage and other work. [0003] At present, inflatable rubber airbags are mostly used in smaller engineering cases, such as the laying of submarine pipelines in shallow water areas. Usually, airbags with smaller diameters (such as 800mm) are inserted into the pipelines, and air with sufficient ...
