Definitions
- the invention relates to a nozzle jet device for producing a nozzle jet element in the ground, with a linkage which has a central suspension pipe and an air supply.
- Such nozzle jet devices are used, for example, in the so-called HDI ner process (high-pressure injection process).
- a rod actuation device is used, which is connected to a drill rod
- a disadvantage of these known north directions or ner driving is the energy loss when delivering the suspension due to the fluidically unfavorable course of the pipes carrying the suspension.
- the object of the present invention is to create a device of the type mentioned at the outset by which the suspension jet is optimized in terms of flow technology in a simple manner when producing a jet nozzle element in the ground.
- a nozzle carrier is arranged in an end section of the linkage, in which nozzle regions of the suspension tube and the air supply lie at an angle to the linkage.
- a continuous curve is created between the vertical suspension pipe or the air supply and the angular, preferably horizontally arranged, mouth areas of the nozzle carrier, thereby ensuring that the suspension jet delivers an optimal flow.
- a valve opening towards the mouth area can be arranged between the suspension pipe and a part of the suspension pipe ending in the mouth area of the nozzle carrier, which valve can be designed, for example, as a spring-loaded, adjustable ball seat valve.
- the nozzle holder can be designed, for example, as a pear-shaped or double-conical housing in outline.
- replaceable nozzles can be used in the mouth areas for the suspension according to the soil to be worked, which nozzles can have different sections of constant slope, for example.
- the rod is designed as a drill rod, wherein this drill rod can have an end-face reamer with a drill bit.
- FIG. 1 shows a schematic section through a nozzle holder when used in a hole in a soil
- Fig. 2 is an enlarged view of another nozzle in the area of section A of FIG. 1, in the middle section.
- FIG. 1 shows a nozzle jet device 1 for producing a nozzle jet element 2 in the soil 8.
- An end-side reamer 3 with a drill bit 4 and an adjoining, vertical drill pipe 5 can be used.
- This vertical drill pipe 5 has a central suspension tube 10 and an air supply 12, which surrounds the suspension tube 10.
- a separate water channel can be used.
- a nozzle carrier 20 is arranged between an end section 14 of the vertical drill pipe 5 and the reamer 3.
- this nozzle carrier 20 are z. B. horizontally to the drill pipe 5 mouth areas 22 and 24 of the suspension tube 10 and the air supply 12.
- a valve 30 which opens towards the mouth is arranged between the vertical suspension pipe 10 and a horizontal part 26 of the suspension pipe 10 which ends in the mouth region 22 of the nozzle carrier 20.
- This valve 30 is designed, for example, as a ball seat valve, with a ball 34 as well as a spring 32 and an adjusting element 36.
- the pressing force of the spring 32 against the ball 34 can be regulated by this ner adjusting element 36, which is supported, for example, in a threaded opening.
- the nozzle carrier 20 is designed as a pear-shaped housing, and has a part 10 'of the vertical central suspension tube 10, the air supply 12' surrounding this tube 10 'and the horizontal part 26 of the suspension tube 10, the corresponding air supply and the mouth areas 22 and 24 for the suspension or for the air.
- the nozzle holder 20 can e.g. B. also have a double-conical shape. It can be seen from detail A that replaceable nozzles 40 (or according to FIG. 2) 40 'can be inserted into the mouth region 22 for the suspension. These nozzles are designed in accordance with the soil 8 to be worked, can be exchanged in a simple manner in the nozzle carrier 20 and have different sections with a preferably constant slope.
