SU549550A1 - Device for the formation of horizontal wells in the ground - Google Patents

Description

The invention relates to construction and can be used to form horizontal wells in a rod. For trenchless laying of pipelines.

A device for forming horizontal wells in the ground is known, which includes a housing with an actuator driven by it, the shaft of which has a propeller knife and a blade section with a ripper, and a device for removing soil.

During the production of works by a known device in plastic soils, there is a significant decrease in the productivity of the device due to the incomplete loosening of the accumulated in the bottomhole and compacted soil. The reason for this is the diametrically opposite arrangement of the compartments of the blades on the hub of the working body in the same plane.

In addition, in plastic soils, due to the short length of the bay, their lolaisses, the soil collected by the shovel is not completely cut off from the whole mass of soil, however (partially forgotten, and maintains a connection with it), and when shoveling off, the shovel remains in bottomhole, which leads iK insufficient filling of the scrim.

The goal of the acquisition is to increase the productivity of the device by improving soil loosening and removing it from the bottom.

In order to achieve this goal, the cut-off blades are installed displaced one relative to another in the vertical area, with the rippers facing the inside of the space formed by the blades.

The drawing shows the proposed device.

The device for the formation of horizontal wells in the soil has an “opus 1 with a visor- .2, drive 3, a scoop 4 for removing soil from the bottom, a hub 5 with two hinged pro-proleros-like blades b and two interlocking lonastes 7,

located at an angle of 180 ° and offset one from another in a vertical plane, with rippers 8, facing inside the space formed by the blades, and locking elements 9. The cutting blades 7 are hinged.

The device works as follows. The propeller-shaped knives 6 and the cutting blades 7 are fixed by means of the elements 9, in a position perpendicular to

Prod axle hub 5. After turning on

drive 3 and feed device (.MexamiSiMbi

the supply is conventionally not shown) together with the pipe being laid, the rotating knives 6 make the development of soil into the well. Rotating simultaneously with shut-off blades 6 nozhalsh 7 and 8 is produced rippers m beopreryvnoe loosening accumulated .grunta generated in the bottom in the zone between rasholozhennoy blades 7. The primer "Alila to visor 2, and then the resulting them sickle Nole compacted soil, continuously cuts off the cutting blade 7 closest to the end surface of the laid pipeline (device body 1), which makes it impossible to increase the compacted mass in the direction of the bottom length.

The soil accumulated in the bottomhole is periodically removed from it by means of a scoop 4. During the period of soil collection, the cutting loops / mouths completely cut off the soil that entered the scoop from the rest of its mass in the bottomhole, thus preventing its return from the scoop to the bottomhole.

If it is necessary to supply the device inside the laid pipe and then withdraw it from it, the cutting blades 7, as well as the propeller-shaped knives 6, are fixed in an inclined position by means of the fixing element 9.
