Floating body of mud discharge pipe

Abstract

The invention discloses a floating body of a mud discharge pipe, and belongs to the technical field of the design and manufacturing of a mud discharge pipeline used in dredging engineering. The technical scheme is that: the floating body of the mud discharge pipe comprises two half-pipe floating bodies which consist of a metal reinforcing framework layer and an elastic material layer and have a structure of an inner wall layer, an outer wall layer and a closed cavity, and is characterized in that: the whole surface of the metal reinforcing framework layer is coated with the elastic material layer. Compared with the prior art, the invention has the obvious progress and prominent substantial characteristics that: the floating body of the mud discharge pipe keeps high technical characteristics in the prior art, has higher corrosion resistance, longer service life, lower using cost, is more convenient and quicker to install and transport, and the like.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of a mud discharge pipeline used in dredging engineering, in particular to a mud discharge pipe floating body. Background technique [0002] Mechanical dredging projects such as river courses, waterways, harbor basin dredging, harbor shoals, and wharf foundation trenches all require sludge discharge pipelines connected by sludge discharge pipelines to realize transportation. As the mud discharge pipe in the mud discharge pipeline, various self-floating metal mud discharge pipes have been used so far. Once the self-floating metal mud discharge pipe is damaged, the entire pipeline will be scrapped, and the cost is high. In order to solve this technical problem, more and more bundled metal mud discharge pipes are used, and the core of the bundled metal mud discharge pipe is the floating body of the mud pipe. With the floating body of medium density polyethylene, rubber The finished fl...

Problems solved by technology

But there are also some shortcomings, that is, the bolt connection in the metal reinforced skeleton, the cavity surface between the inner wall layer and the outer wall layer without anti-corrosion surface treatment has poor corrosion resistance, especially in seawater Under immersion and sunlight exposure, the rust is particularly prominent, which directly affects the service life of the floating body; in addition, due to the large volume of the floating body, only taking the mud discharge pipe with an inner diameter of Φ800mm as an example, the outer diameter of the floating body is Φ2000mm , the inner diameter of the floating body is Φ840mm, and the length is 2250mm. The handling process requires special equipment and accessories such as cranes and ropes, which brings a lot of inconvenience to the installation and transportation process.
