XPB-20B jet grouting rig a walking rig main purpose of this model can be used for all kinds of soft foundation reinforcement, high-rise building basement seepage treatment, remediation, rail road bridge pier reinforcement of major rivers such as inscriptions. Through a combination of different modules that can fit a given spray, put spray, jet grouting and other construction technology; Single, double, triple jet grouting and other construction requirements. 2, the main features of 2.1 rig, rig adapt better performance, supporting different modules, different drilling projects can meet different needs. Users can configure according to their actual needs to be put in the best cost performance rig construction, and can constantly update modules to solve different jet grouting process. 2.2 rig during construction, drilling and jet grouting can be completed. 2.3 rig with full hydraulic technology: drill head gear, lifting and drilling rigs from the tower, are used in the hydraulic control, flexible operation, maintenance saving time, effort. Hydrostatic facilitate special road construction site, to facilitate the construction personnel to operate. 2.4, the new rig can be used winches, hydraulic control application, greatly reducing the labor force, improve production efficiency and improved security protection of construction workers. 3, the rig main performance 3.1, into the hole parameters (according to user needs, providing a variety of drilling.)
