Open shield

The choice of use of this type of drilling is largely influenced by the type of ground to be drilled.

The absence of water tables is essential and the ground to be drilled must be cohesive. Its use is not advisable in very loose and cohesionless soils, very resistant or in the presence of water.

The execution of open shield pile driving is carried out by means of a shield that incorporates a drilling element, which varies according to the terrain to be excavated, bucket, miner, pickaxe, etc.

The extraction is carried out by means of trolleys, the shield is guided by orienting the moving part of the machine by means of the orientation cylinders and aided by the laser that hits a target and the levels that indicate the trend.
