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

Embodiment 1

[0019] The mud discharge pipe floating body of embodiment 1 of the present invention (referring to figure 1 , figure 2 ), it is formed by the fastening connection of two semi-tubular floating body bodies through the bolts inserted in the bolt sockets 4. The metal reinforced skeleton layer of each floating body is a semi-tubular hollow structure formed by steel plates through cutting, pressing, welding and other processes. It includes a semi-tubular floating body outer wall layer 1 and 2 semi-circular The end 2 of the floating body, a semi-tubular floating body inner wall layer 3 and a closed cavity 5 in a hollow structure formed by processing them into a whole form an integral metal reinforcement skeleton layer of the floating body. In order to strengthen the corrosion resistance of the metal reinforced skeleton layer and improve the corrosion resistance, the entire surface of the entire metal reinforced skeleton layer is coated with a vulcanized rubber material layer as the...

Embodiment 2

[0022] The mud discharge pipe floating body of embodiment 2 of the present invention (referring to image 3 , Figure 4 ), it is formed by the fastening connection of two semi-tubular floating body bodies through the bolts inserted in the bolt sockets 4. The metal reinforced skeleton layer of each floating body is: the inner wall layer 3 of the semi-tubular floating body and the joint 9 of the floating body are integral structures, and the outer wall layer 1 of the semi-tubular floating body is a frame structure. Two bolts in the transverse section On the semi-circular arc surface of the outer wall layer 1 of the floating body body of the socket 4, an arc-shaped steel plate is set up and welded with the junction of the floating body body 9, instead of the semi-circular arc surface of the bolt socket 4, an interval is set. Curved steel plate structure. The joints of the semi-conical frustum-shaped heads 8 at the ends 2 of the two floating body bodies and the outer wall layer ...

Embodiment 3

[0026] The mud discharge pipe floating body of embodiment 3 of the present invention (referring to Figure 5 , Figure 6), it is because the working environment and conditions are more severe, and the mud discharge pipe is required to have a strong ability to resist wind and waves, anti-collision, long continuous operation time, convenient and quick maintenance in the mud discharge pipeline, especially fast replacement of the mud discharge pipe, etc. A kind of mud discharge pipe floating body designed for a specific requirement. Except that the technical solution described in this embodiment is the same as the technical solution described in Embodiment 1, the other differences mainly include the following points: one is that the metal reinforced skeleton layer of the floating body body is extended along the axis, and at the end of the shaft Part 2 adds an elliptical head 8 (it can also be a hemispherical head, or a spherical head) to further decompose and reduce the impact fo...

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...
