Abstract

The utility model relates to a self-floating type mud discharging pipe used for the over-water construction of dredgers. The self-floating type mud discharging pipe is characterized in that the pipe wall of the pipeline of the self-floating type mud discharging pipe has a multilayer structure which comprises an inner rubber layer arranged on the innermost side, a cord reinforced layer wrapped and rounded on the inner rubber layer, a middle rubber layer stuck on the cord reinforced layer, a bulked layer stuck on the middle rubber layer, a hoop layer stuck on the bulked layer, and an outer rubber layer stuck on the outermost side, which are arranged orderly from inside to outside, wherein, the inner rubber layer, the middle rubber layer and the outer rubber layer are all made of rubbery material; the expanding body layer is made of bulked materials of low-density. The utility model has the advantages of no need of the support of a floating canister when used, simple structure, convenient and reliable use, and long service life.

Description

The self-floating mud pipe
The utility model relates to a kind of self-floating mud pipe that is used for the dredge boat over-water construction.
Existing and the matching used mud pipe of dredge boat rely on the steel floating drum and support and exceed the water surface during work, center of gravity is higher, easily overturning and influence construction in the high sea.Steel floating drum not only volume is big, heaviness, and transportation and assembling are extremely inconvenient, and easy-to-rust, and application life is short, need often keep in repair, change.
The purpose of this utility model provides a kind of floating drum that do not need and supports, and is simple in structure, easy to use, reliable, the self-floating mud pipe of long service life.
The technical solution of the utility model is, this self-floating mud pipe comprises a segment pipe and is fixed on the mounting flange of pipe ends, it is characterized in that, the tube wall of described pipeline is a sandwich construction, they are followed successively by the most inboard inner glue layer from inside to outside, surround curtain cloth reinforced layer on the inner glue layer, be attached to mesoglea on the curtain cloth reinforced layer, be attached to varicosity layer on the mesoglea, be attached to the hoop layer on the varicosity layer and be attached to outermost outer glue-line, described inner glue layer, mesoglea and outer glue-line all are elastomeric material, and the varicosity layer is made by low-density varicosity material (as the EVA material).
The utility model has the advantages that, owing to do not need the support of steel floating drum when using, not only good stability, and transportation, easy to assembly, corrosion-resistant, the life-span is long.In addition, the utility model has increased varicosity layer and hoop layer than common spoil disposal sebific duct, has not only had and self-buoyancy, and has improved its withstand voltage properties, uses more reliable.
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, the pipe ends of this self-floating mud pipe is fixed with the flange 1 of steel, the tube wall of pipeline is a sandwich construction, they are followed successively by the most inboard inner glue layer 2 from inside to outside, surround curtain cloth reinforced layer 3 on the inner glue layer, be attached to mesoglea 4 on the curtain cloth reinforced layer, be attached to varicosity layer 5 on the mesoglea, be attached to the hoop layer 6 on the varicosity layer and be attached to outermost outer glue-line 7, described inner glue layer 2, mesoglea 4 and outer glue-line 7 all are elastomeric material, and the varicosity layer is made by low-density varicosity material (as the EVA material).

Claims (2)
