Description

I

The invention relates to the construction and can be used in the construction of closed, drainage, sewer systems and water conduits, as well as in cases when it is necessary to manufacture a rigid and metal pipeline directly in the ground.

A working tool for the trenchless installation of underground pipelines is installed on the base machine, including an axle with a drainer attached to its lower part and a pipeline system with mixture supply nozzles used to form the wall of the pipeline, as well as an inflatable formwork that is fed into the mole directly behind drenerom but the extent of its movement.

The purpose of the invention is to provide the possibility of laying a pipeline of various lengths with the formation of internal formwork from the developed soil.

For this, the draener is made in the form of an нол-cylinder, the rear end surface of which is made with a bevel, there are nozzles on it and a reflector above it, and a cutting edge is formed on the front end surface of the drainer, and an annular chamber is located in the edge of the drind end surface lubricant supply to the internal and disruptive surfaces of the drainage machine.

The drawing shows the proposed working body.

The tool for trenchless laying of the pipeline, mounted on the base machine, includes a knife / with a draining machine 2 attached to its lower part and a piping system 3 with nozzles 4 for feeding the mixture used to form the wall of the pipeline 5. The draining machine is made in the shape of a new cylinder, its rear face the surface is made with a bevel 6 (the crown 4 and the reflector 7 are installed evenly on the surface), and an edge S is formed on the front end surface, and at the edge in front of the end surface of the draining unit put the annular chamber 9, for its lubrication nntani nodaets but line 10.

When the working tool is in operation, the knife / is buried in the ground along the road, which was previously prospected by probes and from which all large non-ground inclusions were extracted beforehand.

Simultaneously with the beginning of the movement of the base machine, the mixture is fed to the pipelines 3n lubricant to the pipeline 10. As a result of the knife moving with the draining machine 2, a mole // and a cylindrical solid core 12 inside are formed that make up the outer and inner formwork, respectively, for forming the pipeline mix 5. At the same time, the formation of a core is facilitated by the execution of a draener, in the form of a hollow cylinder, and by preventing the drawdown and destruction of the core upon exiting the draine, until the mixture “sets,” view of the rear end surface of the Draener in the form of a bevel 6 back and down. Refractor 7 prevents the extrusion of the mix up through the slot 13 formed by the primer with the knife I, since fast-hardening materials, such as concretes, polymers, dry mixes, etc., are used as a mixture for shaping the pipeline, the core is removed by scouring with a small time gap. The subject matter of the invention 1. A working tool for trenchless laying of a pipeline, mounted on a base machine, including a knife with a draenero attached to its lower part and a piping system with nozzles for feeding the mixture used to form the wall of the pipeline, characterized in laying a pipeline of various lengths with the formation of internal formwork from the soil being developed, the draining unit is made in the form of a hollow cylinder, the rear face of which is made with a bevel, on it ovleny nozzle and drink over - the reflector, and on the front end noverhnosti dreiera formed cutting edge. 2. The tool according to claim 1, characterized in that, in order to supply lubricant to the inner and outer surfaces of the draining unit and reduce its thrust resistance, an annular chamber is located in front of the end surface of the draining unit in the cutting edge.
