Description

The invention relates to the construction and can be used in the construction of supporting structures in the ground using inkjet technology.

A jet monitor is known, including a housing with inlet pipes for water, compressed air and a solid solution and side and end nozzles.

The operation of the monitor of the monitor consists of lowering a drill hole in the preliminarily n1 and breaking up the soil of the cavities with water from the side nozzles of the monitor under the protection of the air jacket, and simultaneously filling the cavity of the cavity with a hardened Cl3 solution. it only works in a pre-drilled guide hole, which reduces speed and increases its cost.

The closest to the invention in terms of technical and achievable result is an inkjet monitor, including a housing with a hydraulic cavity, pipelines for compressed air and a working agent, side and torus, an ejector nozzle and a switch for the direction of action of a jet made in a spring-loaded hollow piston interacting with cilidrom and face nozzle 2

A disadvantage of the known device is its low reliability, since the valve is triggered when the amount of water pressure that can vary during operation is changed, as well as the limited range of its use, since erosion of solid soil in heavy soils should be carried out with high water pressure, which causes srabagyvanie valve and overlapping urban nozzle.

The aim of the invention is to increase the reliability of the device and expand the range of its application.

This goal is achieved in that in an inkjet monitor including a housing with a cylindrical cavity,. piping d 'compressed air and working agent ,, side and end nozzles and jet direction switching valve, made in the form of a spring-loaded hollow piston interacting with a cylinder and face nozzle, the piston is provided with an annular collar placed on the annular surface, and a groove for interacting with the collar, while the groove is a common point with a pipe for compressed air.

FIG. I shows the proposed jet monitor in the position intended for erosion of the well (jet outflow; water from the face nozzle) in FIG. 2 / - the same for erosion from the wellbore (discharge of the water jet from the side nozzles),

; The device includes a cylindrical kopnyq 1 with attached water supply pipes 2, compressed air 3, and a hardening solvent (not shown), side 4 and front 5 sockets, and a jet direction switching valve, which comes from the hollow cylinder 6, spring loaded. spring 7, and having a locking rod 8, In the hollow cylinder 6 there are holes 9 that allow pressure water to flow through the cavity of cylinder 6 into face nozzle 5. The cylinder 10 present on cylinder 6 forms an air cavity 11 in the cavity of housing 1, which is connected with channel A compressed air pipe 3 is provided in the housing 1. There is an opening 12 in the housing 1 for discharging water into the cavity of the housing 1..

The device works as follows

The iodine is supplied with an iodine with the necessary pressure of water. The valve remains in the upper position, and the water, the passage through the valve cavity and the openings in it, expire from the end nozzle. When this occurs, the erosion of the well with a gradual lowering of the monitor. The pressure of the water jet at the same time can be selected from the condition of the optimal erosion regime and for dense soils it is equal to the maximum developed by an application pump.

But when the well reaches the desired depth, the monitor is supplied with compressed air, which is required by technology to form a protective air casing around the jet. This activates the valve, which closes the face nozzle and directs the water to the side nozzles,

As the soil is washed away by water struts, a gradual
