Rotary jet mixing stiffening pile is a kind of oblique cement cement stiffening anchor solid formed by combining rotary jet grouting and mixing cement soil technology, and combining prestress and soil reinforcement technology. The strength of the slope soil is greatly improved, and the bearing capacity and stability of the slope soil are improved. At the same time, the anchor cable can obtain a high anchorage force to provide support for the foundation pit and slope stability.
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 patent82 Item, Appearance design7To 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 principle:
Rotary jet mixing stiffening pile is a kind of oblique cement cement stiffening anchor solid formed by combining rotary jet grouting and mixing cement soil technology, and combining prestress and soil reinforcement technology. In the process of pile formation, the soil around the pile is cut, stirred, penetrated, extruded and displaced, so that the strength of slope soil is greatly improved. Under THE ACTION OF PRESTRESSED ANCHOR BARS, THE STRESS STATE OF SLOPE SOIL IS CHANGED, AND THE BEARING CAPACITY AND stability OF slope soil ARE IMPROVED. At the same time, the anchor cable has a higher anchorage force, which provides support for foundation pit and slope stability.

Advantages of process:
Stiffened PILE IS SUITABLE FOR THE SUPPORT OF DEEP FOUNDATION PIT IN ALL KINDS OF SOIL LAYERS, AND IT is superior TO THE TRADITIONAL pile ANCHOR, gravity DAM and soil nAILING wall support technology in terms of safety, economy and construction convenience.
(1) The space required for the construction of rotary jet mixing stiffened pile is not large, which is suitable for all kinds of terrain and site;
(2) by spinning spray stirringInstead of inner support, the stiffened pile can reduce the cost of the enclosure structure35%Above, improve the excavation of soil and underground structure construction conditions, shorten the construction period40%Or so;
(3) The anchoring force of rotary jet mixing stiffened pile can be determined by on-site tension detection, and the tension detection of each pile can easily test the construction quality of rotary jet mixing stiffened pile, so as to ensure the safety of foundation pit engineering;
(4) The lateral displacement of support structure can be effectively controlled by applying pre-tension;
(5By controlling the bond force between anchor reinforcement and soil-cement pile, the anchor reinforcement can be recovered.
