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

[0034] Please refer to Figure 1 to Figure 5 A specific embodiment of a composite foundation reinforcement device of the present invention is shown.

[0035] The composite foundation reinforcement equipment is used to form pile holes on the natural foundation and add sand and gravel to the pile holes through the composite foundation reinforcement equipment, thereby forming a composite foundation, and building multi-storey or small high-rise buildings (less than or equal to 11-story building).

[0036] In this embodiment, the composite foundation reinforcement equipment includes: the second vibration generating mechanism 30 , the connecting sleeve 20 and the first vibration generating mechanism 10 which are vertically and sequentially rigidly connected. The second vibration generating mechanism 30 is preferably a vibrating hammer, and can be fixedly placed on the top of a tower crane or a pile mixer.

[0037] The bottom of the second vibration generating mechanism 30 is provi...

Embodiment 2

[0051] The main difference between this embodiment and Embodiment 1 is that, in this embodiment, the connecting member 202 is columnar, and connects the outer tube 201 and the inner tube 203 in a circular shape at uniform intervals on the same horizontal plane. The number of columnar connectors 202 can be 4 or 6 or more, as long as it is ensured that sand and gravel can fall down smoothly from the gap 211 .

[0052] For the same technical solutions in this embodiment as in Embodiment 1, please refer to the description in Embodiment 1, and details are not repeated here.

Embodiment 3

[0054] ginseng Figure 6 As shown, the main difference between this embodiment and Embodiment 1 and / or Embodiment 2 is that, in this embodiment, the number of plate-shaped connectors 202a is three, and they are arranged horizontally at an angle of 120 to each other. To connect the outer tube 201 and the inner tube 203. At this time, the gap 211 is composed of three arc-shaped openings 211a.

[0055] For the same technical solutions in this embodiment as in Embodiment 1 and / or Embodiment 2, please refer to the description in Embodiment 1 and / or Embodiment 2, and details are not repeated here.

Abstract

The invention provides composite foundation reinforcing equipment. The composite foundation reinforcing equipment comprises a second vibration generating mechanism, a connecting sleeve and a first vibration generating mechanism, wherein the first vibration generating mechanism comprises a vibration damper, a top connecting sleeve, a motor, a first vibrating part and a water injecting head; the connecting sleeve comprises an outer sleeve, an inner sleeve and a plurality of connectors, and the outer sleeve and the inner sleeve are arranged in a sleeved manner; the outer sleeve and the inner sleeve form a non-polygonal gap for allowing sand and gravels to circulate; the top of the inner sleeve is provided with a suspending mechanism which is rigidly connected with the second vibration generating mechanism; a hollow channel is formed inside the vibration damper; a water conveying channel which penetrates through the first vibration generating mechanism, the top connecting sleeve and the vibration damper, and communicates with an outer water source is arranged in the water injecting head; and the first vibration generating mechanism and the second vibration generating mechanism jointly implement two-way vibration. The composite foundation reinforcing equipment can realize two-way vibration of longitudinal impacting and transverse hole expanding on a natural foundation, and the natural foundation can be softened by injecting water, so that the adaptation and the construction efficiency are improved.

Description

technical field [0001] The invention relates to the field of foundation reinforcement equipment, in particular to a composite foundation reinforcement equipment. 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 composed 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 dispersed mat...
