SP-30B horizontal rotary spray rig Horizontal Jet Grouting in horizontal drilling in a high pressure water jet grouting way to mud, the outer contour of the excavation of the tunnel lining arching pre-order protection ahead of the tunnel face and surface subsidence Support Construction Methods. Practice has proved that the level of jet grouting pile is effective and fast at home and abroad ahead of the economic tunnel support technology, has broad prospects for application. Company on the basis of a large number of studies on the use of theoretical analysis of jet grouting pile driver has been further improved, and the use of a number of technical innovations, according to the needs of the construction, production and utility models of small horizontal jet grouting pile. A small rig Scope: jet grouting pile, foundation bolt holes, pneumatic DTH drilling and other construction process for the city foundation reinforcement, mine broken hole, railway, highway tunnel roof holes, bolt holes, Construction of drainage holes. Second, the main features: 1, horizontal rotary spray rig to adapt to performance, all-hydraulic drilling rig technology, less wearing parts used in construction, convenient and flexible user operation, maintenance saving time, effort, greatly improve the efficiency of construction. 2, the rig during construction, drilling and jet grouting can be completed. 3, the wide scope of the rig, supporting different modules, different drilling projects can meet different needs, a multi-purpose machine. 4 small rig models, site unrestricted. 5, the rig light as easy to move.
