Abstract

The invention relates to construction and can be used for trenchless laying of pipelines. The goal is to increase productivity when working in soils with different properties. For this, the device is made with an additional working chamber 6 with a guide tube 7, which is coaxially mounted on the guide tube 5 of the main chamber 1, and with an additional sleeve 8, one end of which is fixed to the tube 5, and the other end is turned out and fixed on the guide sleeve 7. The device has a working body with a movable pusher 10, made with a bevel 11 on the front end and placed in the internal cavity of the working body. The latter is made with through grooves 12 on its side walls, in the grooves of which retractable wedges are placed, with one end hinged to the body 9 of the working body. The pusher 10 communicates with the front end with the sliding wedges 14, and the other end with the main sleeve 4. The sleeve 8 interacts with the housing 9. The camera 6 communicates with the source 15 of the working agent supply. The working body is inserted into the ground, which is weakened by the impact of the wedges 14. When the working body moves forward, the wedge 14 under the action of the soil goes through the grooves inside the housing 9. The pusher 10 moves under the action of the wedges 14 towards the chamber 1. 1 Il.

Description

The image of the grid relates to the construction and can be used for trenchless laying of pipelines under existing communications. The purpose of the invention is to increase productivity when working in soils with different properties 1-1i.

The drawing shows the proposed; device.

The pipeline laying device comprises a working chamber 1, in which a shaft 3, connected to an engine (not shown), has a drum 3 with a sleeve 4 wound around it, the free end of which is turned inside out and fixed to a guide pipe 5. On a guide pipe 5 coaxial to it, an additional chamber 6 is installed with a directing nozzle 7 and an additional sleeve 8, one end of which is fixed to the guide tube 5 and the other end of sleeve B is fixed to the nozzle 7. In front of the sleeves 4 and 8 there is a working body, in the hollow case 9 of which a pusher 10 is mounted, which has a bevel 11 at the front end. Pa through the side walls of the housing 9 are through grooves 12 in which retractable wedges 14 are mounted on the axles 13. The sleeve 4 has the ability to move in the internal cavity of the housing 9, and the arm 8 is installed with the possibility of interaction with the end of the housing 9. The internal cavities of the main chamber 1 and the additional chamber 6 communicate with the source 15 of the working agent supply. The device for laying the pipeline works as follows.

The main 1 and additional 6 chambers are connected to a source of 15 working agent feeds, with the sleeves 4 and 8 affecting the body 9 of the working body, which is inserted into the ground. When the resistance of the soil to the introduction of the working body increases, increase the pressure of 8 in the chamber 1. The sleeve 4 acts on the pusher 10, moving it forward. The bevels 11 at the front end of the pusher 10 interact with the wedges 14 and rotate them relative to the axes 13. In the process, the wedges 14 extend from the grooves 12 of the body 9 and penetrate the ground, pushing it apart. Then, by rotating the drum 3, the sleeve 4 is wound on it and the pressure in the additional chamber 6 is increased.

In the ground, which is weakened by the impact of the wedges 14, and when the working body moves forward, the wedge 14 under the action of the soil through the grooves 12 leaves inside the housing 9. The pusher 10 under the action of the wedges 14 moves towards the chamber 1. After this, the cycle is repeated.

With a sharp release of the drum 3, the sleeve 4 can transmit to the pusher 10, and consequently, to the 1llin 14, the dynamic loads that occur when the sleeve 4 is accelerated to the pusher 10.
