Low-altitude, under-bridge, under-railroad, under-road bridge, and under-power-line casing conveyance type down-the-hole hammer method!
We would like to introduce our "Low-Headroom Casing Continuous Down-the-Hole Hammer Method LH-CDH Method." By using a special bit and continuously installing protective steel pipes for the borehole walls, we can reliably excavate to the designed height even in collapsed layers with high groundwater levels. After excavation, the steel pipes are left in place, allowing for the extraction of the hammer bit, which ensures that core material installation and solidification with mortar can be carried out effectively. Please feel free to consult us when you need our services. 【Construction Examples (Partial)】 ■ LH-CDH Method - Height restriction: 4.55m (under highway bridge) - Steel material: H300 L=11.5m continuous pile construction - Construction machinery: RX2300 low-headroom construction machine HGS60 *For more details, please download the PDF or feel free to contact us.
