YHZJ Series Crawler Grouting Drilling Rig (Engineering Drilling Rig)   مقدمة المنتج For deep well conditions (over 50 meters), the chip removal capacity of the YHZJ series grouting drilling rig is superior to that of rigs using pump suction or jet reverse circulation. It is therefore suitable for deep well operations, water-scarce arid areas, and frozen soil layers in frigid zones. The main applications of this grouting drilling rig include grouting reinforcement, reinforcement drilling and grouting, settlement grouting reinforcement of highway subgrade, railway subgrade reinforcement, general subgrade reinforcement, and building grouting. Scope of Application Suitable for grouting holes, threading holes, foundation pile acoustic testing holes, and core drilling holes for projects including subways, airports, expressways, high-speed railways, building reinforcement, and ground survey.
