Tianjin-strong high-pressure pump plant in soft foundation treatment, factory-made and develop a high level of domestic series of high-pressure pump, high-pressure mud pump and in cooperation with Water Machinery Plant Laizhou high jet overhead trolley. What is the high pressure jet grouting pile triple tube technology: by improving ordinary single pipe high pressure rotary jet nozzle design soft-processing equipment construction image grouting method to achieve the implementation of the two media can not afford to drill in the case were different nozzle aperture alternating injection, to achieve the desired jet homestead soft foundation treatment of various media, to expand the pile diameter, improve efficiency purposes. Introduced its nozzle design and operating principle, on-site construction process and results. Above drill rig equipped. According to market needs, we have developed a large number of jet grouting drilling cofferdam seal Curtain soft foundation treatment, to meet the various needs of users, such as Single, double, triple, fixed spray, spray swing tool. A combination of convenience. Users can select different combinations according to their development, so as to obtain better cost performance of equipment.
