Problems solved by technology
[0004] The current composite foundation reinforcement equipment has the technical defect of low drilling and reaming efficiency in the process of reaming natural foundations and filling sand and gravel, especially when drilling holes on natural foundations with different densities or different moisture contents. Poorly adapted technical flaws in the process of reaming and filling sand and gravel to form a composite foundation

Embodiment 1
[0037] Please refer to Figure 1 to Figure 8 Shown is a specific implementation of a composite foundation reinforcement construction method of the present invention.
[0038] The composite foundation reinforcement method can be used in the construction of composite foundation, and is used to form pile holes on the natural foundation through specific composite foundation reinforcement equipment, and sand and stone are added to the pile holes through the composite foundation reinforcement equipment, thereby forming a composite foundation, and Build multi-storey or small high-rise buildings (buildings less than or equal to 11 floors) on composite foundations.
[0039] A kind of composite ground reinforcement construction method shown in the present invention comprises the following steps:
[0040] First, step S1 is executed to determine the pile point position.
[0041] Then perform step S2, vertically align the first vibration generating mechanism 10 at the bottom of the compo...

The invention provides a composite foundation stabilization construction method. The composite foundation stabilization construction method comprises the following steps: S1, a pile point position is determined; S2, a first vibration generation mechanism at the bottom of composite foundation stabilization equipment is aligned with the pile point position; the pile point position is rammed and drilled under the driving of a second vibration generation mechanism, so that a vertically-arranged pile hole is formed; after the first vibration generation mechanism drills to a preset depth, the first vibration generation mechanism is started for chambering; then vertical ramming and drilling operation and chambering operation are performed at the same time through the second vibration generation mechanism and the first vibration generation mechanism, so that the pile hole is formed; and S3, the pile hole is filled with gravel so as to form a composite foundation. According to the composite foundation stabilization construction method disclosed by the invention, double-direction vibration for a natural foundation in the vertical direction and the horizontal direction can be simultaneously realized; soil can be softened through water injection with a water injection head, so that chambering operation is accelerated; and construction efficiency for performing composite foundation stabilization on different natural foundations is improved.
Description
technical field [0001] The invention relates to the field of foundation reinforcement equipment, in particular to a composite foundation reinforcement construction method. Background technique [0002] Composite foundation means that part of the soil of the natural foundation is strengthened or replaced during the foundation treatment process, or reinforcement materials are set in the natural foundation, and the reinforcement area is composed of the matrix (natural foundation soil or improved natural foundation soil) An artificial foundation consisting of two parts, the reinforcement and the reinforcement. Under load, the matrix and the reinforcement share the load. According to the load transfer mechanism of the composite foundation, the composite foundation is divided into two types: the vertical reinforced composite foundation and the horizontal reinforced composite foundation, and the vertical reinforced composite foundation is divided into the composite foundation of d...
