Abstract

Improvements in advance devices by shield to open ditches in open shoring and to lay sections of pipe in it, of the type of devices that is composed of a forward shield and a pipeline attached to it and draggable in the forward direction, to which the tubes can be lowered to join the section of pipe already laid, and that on its opposite side to that of the shield it has one with a passage opening for the tubes, characterized in that each shield is constituted of a shield box that is integrates with the pipe laying box forming a closed, pressurized construction unit forward, where to press forward the shield box and the pipeline box is disposed in the latter a forward pressing device that rests against the section of laid pipe.
