High pressure jet grouting pile
Characteristics and application scope of high-pressure rotary jet grouting pile
The high-pressure rotary jet grouting method has the following characteristics: improving the shear strength of the foundation, improving the deformation properties of the soil, and preventing damage and significant settlement under the load of the upper structure; Able to use small diameter drilling and rotary spraying to form a large diameter consolidated body 8-10 times larger than the hole; Various shapes of piles can be formed by adjusting the rotational spraying speed, lifting speed, spraying pressure, and spraying amount of the nozzle; It can be made into vertical piles, inclined piles, or continuous walls and achieve the required strength.
Widely applicable: can be used for foundation reinforcement of existing and new buildings, soil reinforcement or waterproofing of deep foundation pits, subways and other engineering projects; Suitable for various soil layers: suitable for foundation reinforcement of silt, muddy soil, cohesive soil, silt, sandy soil, collapsible loess, artificial fill, and gravel soil; Easy and flexible construction. The equipment is relatively simple, lightweight, with a high degree of mechanization. The entire set of equipment is compact, small in size, strong in maneuverability, occupies less land, and can be constructed in narrow areas; Easy to operate, easy to manage, fast, efficient, versatile, and cost-effective; Can control the shape and reinforcement range of the added solid; Good durability, can be used in permanent engineering; Good environmental protection effect, used for reinforcement of existing building foundations without disturbing nearby soil, low construction noise, and low vibration.
