Abstract
The article provides an analytical review of scientific developments to improve the process of cable laying in general and specifically the working body of the cable layer in the trenchless laying of cables in different geological conditions.
 Using the patent documentation, the search and analysis of materials for the improvement of the working body of the cable layer and the main advantages of trenchless cable laying were carried out.
 The task of trenchless laying is: laying of water supply networks, sewerage, gas pipeline; laying of power supply cables, telephone and fibre-optic cable communication and alarm lines; laying on the bottom of rivers and reservoirs; laying in mountainous areas; replacement of worn-out communications with new ones.
 The article analyzes the improvement of the design of cable-laying with active earth-moving working bodies (ZRO), the principle of operation of which is based on the trenchless method, which has limited working speed and relative working speed, design complexity and low operational reliability.
