Multi-function multi-function rig drilling rig for a variety of formations (soil, clay, sand layers, rock layers, aquifers) directly or circulation drilling. Rig loaded hydraulic impact hammer or DTH impact can be broken rock into the hole operations, meet the liquid discharge, underground micro pile, bolt and cable, geological exploration, geothermal into the hole, foundation reinforcement, slope and other supporting infrastructure construction requirements. After spraying device can be realized with Jet construction method of construction, the tunnel can also explore the pre-construction lead Forepoling and geology. Currently, multi-rig construction projects in our citizens excavation, slope, and other mine tunnel anchor bolt supporting the most widely used. Churning Pile first part of the processing. When a spin near the top of the pile when the nozzle lifting, anchoring jet grouting rig, the following should be top of the pile 1.0m start, Chaoyang jet grouting rig, slow upgrade Jet, Jet for a few seconds, and then slowly lift up 0.5m, until the pile stops pulp surface.
