Rock hole expander

The rock reamer is specially developed for hard stratum operations. It is made of high-strength alloy steel combined with tungsten carbide alloy teeth, capable of withstanding high drilling pressure and suitable for rock strata such as shale and sandstone. With a variety of specifications, the stepped cutter head enhances the rock-breaking efficiency, the hydraulic structure ensures the circulation of mud, and the split design facilitates maintenance. It is applicable to rock directional crossing, roadway expansion and other projects, and is a reliable tool for hard rock hole expansion construction.

Detailed Description

Product features

The rock reamer is specially designed for construction in hard strata. It features a high-strength alloy steel body and a high-hardness tungsten carbide alloy tooth inlay structure, capable of withstanding high drilling pressure and suitable for reaming operations in high-strength rock layers such as shale, sandstone, and limestone. The product specifications are complete, meeting the pipe diameter requirements of different projects. The unique stepped cutter head design optimizes the cutting path and enhances the rock-breaking efficiency. Equipped with wear-resistant diameter retaining strips to ensure the roundness error of the hole diameter after reaming and reduce the resistance of subsequent pipeline laying.

Core advantage

The innovative hydraulic structure design enables efficient mud circulation and reduces the risk of cuttings accumulation. It adopts a split connection method, which is convenient for transportation and on-site assembly. During maintenance, worn parts can be quickly replaced. Optimize the mechanical structure through finite element analysis to ensure construction stability. Laboratory simulation and on-site testing have verified that the cost of hard rock reaming operations has been significantly reduced.

Application scenarios

It is widely applied in horizontal directional drilling crossing projects (such as rock layer river crossing, mountain crossing), mine tunnel expansion, non-excavation construction of rock sections of municipal pipelines and other fields. It is especially suitable for complex projects that require expanding the hole diameter in high-strength rock strata, providing reliable solutions for construction in hard strata.
