Construction method of concrete pouring pile by hydraulic vibration hammer sinking tube

Abstract

The invention discloses a concrete pouring pile construction method by hydraulic vibration hammer sinking pipe. The construction method comprises the following steps: 1) measuring and setting out; 2) casing sinking; 3) drilling with a rotary drilling device; 4) installing a reinforcement cage; Concrete is poured into the hole of the cast-in-place pile of the cage to the hole, the upper part of the pouring conduit is removed, and the lower part of the pouring conduit is kept in the concrete of the pile body, and the length of the lower part of the pouring conduit is controlled at 4m~ 8m, and fix the perfusion catheter on the casing, turn on the hydraulic vibrating hammer to vibrate and pull out the casing upwards, when the difference between the elevation of the top of the casing and the elevation of the ground is 3m to 5m , stop pulling out and vibrating, and fix the sleeve, and complete the first concrete pour; 6) pour concrete for the second time; 7) pull out the sleeve. The construction method has good construction stability, high construction efficiency and low construction cost.

Description

technical field [0001] The invention relates to the technical field of construction engineering pile foundation construction, and more specifically, the invention relates to a construction method of concrete pouring piles by hydraulic vibration hammer sinking tubes. Background technique [0002] Immersed tube cast-in-situ pile is one of many types of pile foundations in civil engineering. It adopts a steel pipe (that is, a casing) that is compatible with the design size of the pile. Hang the reinforced skeleton in the casing, then vibrate or hammer the tube while pouring the concrete, and use the vibration during the tube pulling to compact the concrete to form the required cast-in-place pile. This construction method is often used in environments where groundwater, quicksand, and silt exist. [0003] The traditional construction methods of sinking concrete prefabricated piles include hammering pile sinking method and static pressure pile sinking method. However, the hamme...

AI Technical Summary

Problems solved by technology

However, the hammering pile sinking method has high noise, large vibration, more oily smoke and oil splashes during the pile sinking process, and the construction of residential groups and public buildings in the urban area is greatly restricted; while the static pressure pile sinking method adopts pressure The pile equipment and counterweight are heavy, the thickness of the sediment at the bottom of the pile is difficult to control, the construction stability is poor, the construction efficiency is low, and the cost is high
