Problems solved by technology

However, the vegetation layer constructed by this process on high and steep rocky slopes is not resistant to rain erosion. Once it encounters heavy rain, the vegetation layer is often eroded and collapsed, leaving only barbed wire, resulting in failure of slope protection
There is a kind of fiber silk reinforcing soil planting method, which is a further improvement method of the traditional hanging net guest soil spraying technology. The soil substrate is continuously sprayed by the wet spraying machine, and the spinning machine sprays fiber filaments, but because the fiber filaments are thin and light, they are easily broken with the fluctuation of pressure and the flow of air, and these broken filaments are easily blocked in the spray nozzle. In the filament tube, it is difficult for the current spinneret to eject fiber filaments, it is easy to block, and it is difficult to keep the filament filaments continuously. There are also obvious restrictions on the material of the filament filaments. Generally, only polyester filaments can be sprayed, and the high-pressure fluid is limited to high-pressure air. Due to the limitation of the spinneret, the continuous spinneret planting method has not been effectively promoted and applied

Embodiment 1

[0019] Reference figure 1 , The present invention provides a jet type continuous spinneret, comprising an injection structure 1 for injection of high-pressure fluid and at least one jet 2 connected to it. The jet 2 includes a jet tube body 3, and the jet The pipe body 3 includes a fluid inlet end 4 and an ejection end 5 that are arranged oppositely. The jet pipe body 3 includes a negative pressure section 6, a throat section 7 and a cross-sectional divergent section 8, which are connected in sequence. The negative pressure section 6 is close to the The fluid inlet 4 is provided, the jet tube body 3 is provided with a cross-sectional reducer 9 in the negative pressure section 6, and the jet tube body 3 is provided with filament inlets on the side wall of the negative pressure section 6. Pipeline 10. The filament inlet pipe 10 and the jet pipe body 3 of the jet pipe body 3 form an angle of 45°, and the filament inlet pipe 10 is inclined to the fluid inlet end 4. The filament en...

Embodiment 2

[0023] This embodiment is basically the same as embodiment 1, except that: the filament inlet pipe 10 and the jet tube body 3 of the jet tube body 3 form an angle of 30°, and the filament enters the pipe 10 towards the The fluid inlet 4 is arranged obliquely.

Embodiment 3

[0025] This embodiment is basically the same as Embodiment 1, except that: the filament inlet pipe 10 and the jet tube body 3 of the jet tube body 3 form an angle of 50°, and the filament enters the pipe 10 toward the The fluid inlet 4 is arranged obliquely.

Abstract

The invention discloses a jet type continuous spinning machine and a reinforcing soil plant growing system. The spinning machine comprises a jet structure for high-pressure fluid to be jetted into and jet devices connected with the jet device, wherein each jet device comprises a jet pipe body; each jet pipe body comprises a fluid inlet end and a fluid spraying end; each jet pipe body comprises a negative pressure section, a throat section and a section diverging section which are sequentially connected; each negative pressure section is arranged by being close to the corresponding fluid inlet end; each jet pipe body is provided with a section gradual-reducing pipe on the corresponding negative pressure section, and is provided with a filament inlet pipeline on the side wall of the corresponding negative pressure section. The high-pressure fluid enters the jet devices through the high-pressure fluid inlet ends, and sequentially passes through the negative pressure sections, the throat sections and the section diverging sections; flow cross section of the fluid in each section gradual-reducing pipe is reduced, the flow speed of the fluid is increased, and a negative pressure can be generated nearby; under the action of the negative pressure, filaments enter the jet pipe bodies through the corresponding filament inlet pipelines, and then are jetted together with the high-pressure fluid. By adopting the jet type continuous spinning machine, breaking and blocking of the filaments are avoided, and fiber filaments can be continuously spun.

Description

Technical field [0001] The invention relates to a spinneret, in particular to a jet continuous spinneret and a reinforcing soil planting system. Background technique [0002] In recent years, a large number of mountains, quarries, and many exposed rock fractures have been formed during the construction process, which not only destroys vegetation, easily causes soil erosion, but also damages the ecological landscape. The traditional greening method of rock slopes is to hang nets and spray soil. broadcast. However, the vegetation layer constructed by this technique on high and steep rock slopes is not resistant to rain erosion. Once it encounters heavy rain, the vegetation layer is often eroded and collapsed, leaving only the wire mesh, causing the slope protection to fail. The existing planting method of fiber reinforced soil is a further improvement method of the traditional spraying technology of hanging net and guest soil. It is formed by using wet spraying machine and spinnin...
