In inner-city civil engineering work in the middle of existing pipes, their route and laying depth is often unclear. This is another reason why utilities from all media sectors prescribe manual work for work in the immediate vicinity of supply lines. This cannot be carried out in a cost-covering manner. Every day, contractors have to decide between taking a risk by using hydraulic excavators excessively – or safety through manual work at a high price. The safest and most economical alternative to manual excavation is the use of a suction excavator.
One example of working with suction excavators is the fast and economical construction of house connections for all media. The use of suction technology enables the excavation pit to be excavated at specific points and thus minimized, which leads to a considerable reduction in subsequent costs. Traffic obstructions are significantly minimized due to the smaller area required and the considerably shorter construction times.
The suction excavator can also be used very well for trenchless pipe laying, whether for creating start and finish pits, extracting bentonite or as an important component in the modern keyhole method.
