The waveform guardrail down the hole drilling rig is currently a specialized drilling equipment for national, provincial, and rural road security engineering. It is mainly used in construction scenarios such as waveform guardrail column pile holes, anti-collision protection pile holes, and slope protection drilling holes.
Traditional spiral pile drivers are prone to getting stuck, unable to penetrate hard rocks, and have severely worn drill bits. However, this equipment can directly and efficiently drill holes without the need for blasting or large-scale road breaking, maximizing the preservation of the original roadbed integrity and adapting to complex road conditions in various regions of the country for construction.
The equipment body is stable, the hydraulic control system is sensitive, the drilling verticality is good, the hole diameter is uniform, and the hole depth is controllable. It can accurately drill standard pile holes for conventional guardrail columns such as φ 114 and φ 140. The hole positions are regular and the hole walls are firm. After the pile is planted and poured, the verticality of the column meets the standard and the anti-collision stability is stable, fully meeting the acceptance standards of transportation and highway engineering, and eliminating later problems such as guardrail tilting, loosening, and settlement.
