Tianjin-strong high-pressure pump Co., Ltd. Our company can provide the following requirements for the customers: 1, factory direct products to the lowest price to buy the most affordable things, sale and quality can be guaranteed; 2, to provide construction site guidance, a reasonable choice right construction technology, to complete the construction; 3, to provide drilling rigs operating crew; 4, has a strong and perfect after-sales department independent, accurate and construction issues quick fix anchor site Jet rig, improve construction efficiency, and ensure the construction schedule; 5, both for the construction side of our company, but also drilling rig manufacturing, but also provide free engineering outsourcing! 6, I engaged in geotechnical construction industry for more than ten years old anchor Churning Pile rig, comprising: a railway bridge reinforcement, slope reinforcement, highway pile construction, consolidation grouting curtain dam, tunnel advance support, landslides and other emergency works, excavation Cable-stayed upright and construction, our company has an independent construction team. High pressure jet grouting method was founded in Japan, which is based on the chemical grouting method, using high-pressure water jet cutting technology and developed. Is the use of high-pressure jet grouting drilling rig, the grouting with a nozzle tube inserted into the soil at a predetermined position, high pressure equipment above the slurry becomes 20Mpa high-pressure jet, ejected from the nozzle to impact damage soil. Part of the fine soil material with the slurry out of the water, soil particles remaining in the impact of the jets, centrifugal force and gravity jet grouting rig picture anchor role, and slurry mixing, according to a certain proportion of the slurry soil regularly again arrangement. After the slurry is solidified, they form a consolidated body between the soil and the pile in the soil together constitute the foundation, thus improve the bearing capacity and reduce the deformation of foundation, foundation reinforcement to achieve the purpose. GZB-40C-pressure injection pump injection pump piston stroke parameters: 100mm Ratio: 1 = 7.2545 piston strokes per: 169 times the suction pipe diameter: 50mm diameter discharge pipe: 16 ~ 25mm piston diameter: 45, 50, 55mm output flow: 96,99,110L / Min rated pressure: 42,40,35Mpa (with 90kw motor) 35,30,28Mpa (with 75kw motor) 25,22,20Mpa (with 55kw motor) Motor type: YCT335-4C maximum motor speed: 1340r / Min Dimensions: 3050 * 1800 * 1150mm Machine weight: 3000kg crank 133mm diameter rotary jet sets anchor rig, is not easy to wear, damage; W type transmission, not damaged, does not affect the field of engineering process; Forged head to ensure the service life. What is the gravel pile it? Simply put, is the foundation drilling tube (inner tube into the hole filling gravel) into the hole with a pile driver into the hole with enough depth to gravel poured into the hole, then squeeze the pile formation called gravel piles.
