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] refer to figure 1 , the present invention provides a jet-type continuous spinneret, comprising an injection structure 1 for high-pressure fluid injection and at least one jet 2 connected thereto, 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 which are arranged oppositely. The jet pipe body 3 includes a negative pressure section 6, a throat section 7 and a cross-sectional gradual expansion section 8 connected in sequence. The negative pressure section 6 is close to the The fluid inlet end 4 is set, the jet pipe body 3 is provided with a cross-section reducer 9 in the negative pressure section 6, and the jet pipe body 3 is provided with a filament inlet on the side wall of the negative pressure section 6. pipeline10. The filament inlet pipe 10 forms an angle of 45° with the jet pipe body 3 of the jet pipe body 3 , and the filament inlet pipe 10 is arranged obliquely toward the fluid inlet end 4 . The...

Embodiment 2

[0023] This embodiment is basically the same as Embodiment 1, the difference is that: the filament enters the pipe 10 and the jet pipe body 3 of the jet pipe body 3 forms an angle of 30°, and the filament enters the pipe 10 toward the The fluid inlet end 4 is arranged obliquely.

Embodiment 3

[0025] This embodiment is basically the same as Embodiment 1, the difference is that: the filament enters the pipe 10 and the jet pipe body 3 of the jet pipe body 3 forms an angle of 50°, and the filament enters the pipe 10 toward the The fluid inlet end 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-type continuous spinneret and a reinforcing soil planting system. Background technique [0002] In recent years, during the construction process, a large number of mountains have been excavated, quarried, and many exposed rock surfaces have been formed, which not only destroys vegetation, easily causes water and soil erosion, but also damages the ecological landscape. The traditional greening method for rocky slopes is hanging nets and soil spray broadcast. However, the vegetation layer constructed by this process on high and steep rocky slopes is not resistant to rain erosion. Once a heavy rain occurs, 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 soi...
