Static pressure immersed tube compaction pile side pile construction method

Abstract

The invention discloses a static pressure immersed tube compaction pile side pile construction method. The static pressure immersed tube compaction pile side pile construction method specifically comprises the following steps that 1, deepening design is conducted, and comprises mechanical selection, drill rod design and soil pressing plate design; 2, processing improvement is conducted; 3, field training is conducted; 4, positioning paying-off and hole forming and hole measuring are conducted, wherein hole forming and hole measuring specifically comprises the following steps that (1) a pile driver is in place; (2) spinning to form a hole is conducted; and (3) drill lifting is conducted; and 5, cement soil backfilling and tamping treatment is conducted, specifically, filler selecting and blending and mechanical tamping are included. The static pressure immersed tube compaction pile side pile construction method has the technical effects that an existing pile driver is improved, side pile construction is conducted through a spinning method, the construction period is shortened, and the cost is controlled; the quality is ensured; and operation is simple and convenient, and the environment-friendly effect is achieved.

Description

technical field [0001] The invention relates to the technical field of side pile construction methods, in particular to a construction method for side piles with static pressure sinking tube compaction piles. Background technique [0002] In recent years, with the continuous improvement of environmental protection requirements in the construction industry, traditional pile foundation hole-forming methods such as hammering and vibration have been gradually replaced. The operating radius of the pile driver is relatively large, and the operating radius is limited during the construction of side piles, resulting in an increase in the excavation volume of the slope, which is unfavorable to the project cost and construction period. In view of this problem, the side pile construction method of sinking tube compaction pile of the present application improves the existing pile machine, adopts the spinning method to carry out side pile construction, successfully solves this problem, a...
