Strong foundation has obtained dozens of innovative technologies in pile foundation engineering, foundation pit engineering, water foundation treatment, land foundation treatment, and has been authorized invention patents54Item, Utility model patent82Item, Appearance design7 To promote industrial technological progress as the way of enterprise survival, more than 20 years, in each different period, with continuous innovation results to support the development of enterprises.
Process characteristics
The technology of six-axis cement-soil mixing pile inherits the advantages of good pile formation effect of uniaxial mixing pile, less soil displacement amount of biaxial (uniaxial) mixing pile, small water-cement ratio, high pile strength, good soil reinforcement effect and low cost. It overcomes the defects of low work efficiency, poor stability, low degree of automation and high labor intensity of biaxial (uniaxial) mixing pile. The defects of high cost, large amount of displaced soil and low strength of soil-cement were eliminated.
The CONSTRUCTION safety is greatly IMPROVED AND THE labor INTENSITY OF workers IS GREATLY REDUCED BY ADOPTING THE walking or crawler type automatic walking pile frame instead of the drum type pile frame of double-axis (single-axis) pile. Six pipe grouting method, three pipe grouting method construction instead of biaxial (uniaxial) mixing pile, four pipe grouting two pipe air injection method construction instead of three-axis mixing pile, six pipe grouting method is particularly suitable for the use of silt soil with high water content.
Energy conservation and environmental protection
Compared with the biaxial (uniaxial) mixing pile, the drilling rig of the six-axis cement soil mixing pile is driven by the single shaft instead of the coupling shaft, and the power efficiency and soil cutting ability are greatly improved. Mixing using spiral blades and a large number of cross blade combination, the construction efficiency is biaxial mixing pile12 Times, is the three axis mixing pile2.5Times; It saves electricity compared with biaxial mixing pile70%, save electricity than three axis stirring pile40% Above, the cost is reduced20% The left and right sides.
Equipped with environmental protection cement automatic mixing grouting system to prevent dust pollution.
Application field
The technology OF SIX-axis SOIL-cement MIXING pile is APPLIED TO soft soil foundation soil reinforcement, soil reinforcement in soft soil foundation pit, gravity retaining wall structure of soft soil foundation pit support, steel soIL-cement retaining wall structure and foundation pit water stop curtain.
The technology of six-axis cement-soil mixing pile has been successfully applied in many foundation pit supporting and foundation strengthening projects and achieved the expected research results.
