A kind of construction method of immersed pipe grouting pile

Abstract

The invention discloses a construction method of a sinking tube grouting pile, and aims to provide a construction method of a sinking tube grouting pile which can effectively solve the problem of deflection due to the interference of stones during the pile tube sinking process. It includes the following steps: first, the pile point and the pile pipe are in place, and the pile pipe includes the inner pile pipe, the outer pile pipe sleeved outside the inner pile pipe and the outer lamination pile sleeved outside the inner pile pipe. pipe; second, the pipe sinking process, the pipe sinking process includes the following steps in turn, 1), using the pile sinking equipment to press the pile pipe and the pile point into the soil together until the pile point is pressed into the soil layer with a set depth of H1 meters ; 2), remove the outer laminating tube; 3), use the pile sinking equipment to press down the inner pile tube and the pile tip together; 4), put the outer laminating tube on the inner pile tube, and then, Use pile sinking equipment to press down the outer pressure tube and the outer pile tube together; 5) Return to step 2) and repeat like this until the pile tube and the pile tip are pressed into the soil to a set depth.

Description

technical field [0001] The invention relates to the construction field of cast-in-place piles, in particular to a construction method for immersed-pipe cast-in-place piles. Background technique [0002] Immersed tube pile is one of many types of pile foundations in civil engineering. The system adopts the pile tube that is suitable for the design size of the pile, puts the pile tip on the end and presses it into the soil, then hangs the steel skeleton in the pile tube and pours concrete, and then pulls out the tube, pulls out the pile tube, and uses Vibration and tamping of concrete during pipe extraction form the required cast-in-place piles. During the construction of the current sinking tube pile, if the pile tube encounters stones when sinking the tube, the pile tube is prone to deflection due to the interference of the stone, and the deflection of the pile tube will seriously affect the normal operation of the sinking tube grouting pile. construction.
