SP-30A jet grouting rig horizontal 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. First, the scope: jet grouting pile foundation bolt holes, pneumatic DTH drilling and other construction process for the urban underground garage, top floor hall and other highly restricted group indoor indoor soft soil reinforcement, as well as for reinforced sealing highly restricted within a small tunnel. 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. Third, the main technical parameters: 1, drilling depth 30 -50m 3, drill diameter φ50, φ60 4, drilling tilt angle -10 ° ~ 90 ° 5, the maximum output power head torque 2300 Nm 5, the output speed of a power head -18,45-200rpm (stepless) 6, power head maximum pull force 25 kN
