High Pressure Jet Grouting Construction Technology Control 1, high pressure spraying pile in front of the official construction process test should be carried out into the pile. 2, the construction of the drilling rig placed smooth, drill pipe held vertically, the inclination of not more than 1.5%, the location and design of the rig position deviation of not more than 50mm. Grouting pipe segment elevated lap length not less than 100mm. 3, appears in the grouting process pressure suddenly rise or fall. When a large number of risk pulp unusual circumstances, should be stopped in time to upgrade and grouting to prevent broken pile. 4, strict quality inspection bodies including the consolidation of an effective diameter of the integrity and uniformity of solidification body inspection bodies consolidation, vertical consolidation of the body, the strength properties of solidification body comprises an axial pressure, the horizontal pressure , frost resistance and impermeability, consolidated body of corrosion and durability. 5, pay attention to the device when the start sequence jet grouting. With triple tube, for example, should be no-load starting air compressor, to be operating normally, and then load starting high pressure plasma jet grouting pile foundation reinforcement, then the hole while air and water, so that the air flow and pump pressure gradually rise up to a predetermined value. After the feng shui flow, rotary grouting pipe and start injection pump primer hole rotary jet pile manufacturers, 先向 delivery of water wells can be injection pump until the pump output pressure is normal pump suction pipe to move slurry storage barrels start grouting. To be estimated before the grout has been out of the nozzle after the peak, before beginning upgrade Jet grouting pipe pile, bottom jet grouting. About rig weight issues to how to properly solve the user performance of the rig, using the results are very satisfactory, but some users think that if the rig on an improvement in the weight better. Rig weight for this problem, and how to solve it? Some rig weight is relatively heavy, which gives the machine handling and movement has brought a lot of inconvenience, so the urgent need to improve and make the appropriate adjustments. And currently on the market's anchor rig, jet grouting rig in this area have been brought under control, to meet the user demand for light rig. In fact, the reason why the weight of the rig design is relatively high, mainly in the construction require that, in order to ensure stability, security of the construction process. There is a way to ease the movement of heavy rig that will be installed in the site above the track 准基安 bolt Churning Pile manufacturers, so that you can solve problems corresponding movement of work to reduce the difficulty of handling, it is generally against split rig.
