Betoncső Sajtolás technológia:
Typically, this pipe-pressing method is used to install protective and utility pipes for public utility lines laid under roads and railways.
Pressing requires a slanted sidewall work shaft, which must be completed with enhanced work safety measures.
The condition of pressing is max. ARC. Class A dry, moist soil with obstacles in the drill gauge not exceeding 65 mm.
The groundwater level should be at least 20 cm below the pipe bottom, otherwise the pipe guidance and the stability of the head will not be guaranteed.
If the pressing is carried out in a groundwater environment, water collected in the trenches must be removed. This can be done in the simplest case by open water retention, or in the case of a deep pit, by vacuum sinking of the groundwater table.
