Construction method of vibration concrete pouring thick-wall tubular pile
The invention relates to the technical field of engineering construction, and in particular to a construction method of a vibration concrete pouring thick-wall tubular pile. A resonance-free vibratory hammer, a clamp, an inner pipe, an outer pipe, a middle jacket pipe and a hoist or pile frame are included. The construction method comprises the specific steps that the inner pipe, the outer pipe and the middle jacket pipe are sleeved, and the middle jacket pipe is arranged between the inner pipe and the outer pipe; the three sleeved pipes are fixed by the clamp; the vibratory hammer is started to vibrate and sink the three sleeved pipes, and soil enters the inner pipe and the middle jacket pipe; after vibration and sinking are finished, vibration is stopped, and a pile clamping manner is changed; the hoist is started to statically pull the middle jacket pipe; and the middle jacket pipe is transferred, the vibratory hammer is started, and soil in the middle jacket pipe is discharged out in a vibration manner. The construction method has the beneficial effects that open pipe sinking is adopted, end resistance is small, and the method can be suitable for multiple kinds of soil properties; no virtual soil exists, no hole cleaning is needed, and the construction process is simple and convenient; the inner pipe and the outer pipe have the full wall protection function; little soil is discharged, the soil transport cost is low, and materials are saved; in the whole process, no slurry pollution or resonance exists, and vibration noise is low; and the requirements for environmental protection and safety are met, and high efficiency and economical efficiency are achieved.
