Method for processing concrete cast-in-place pile bottom sediment

Abstract

The invention relates to a method for processing concrete cast-in-place pile bottom sediment. The method comprises the following steps of drilling the top of a concrete cast-in-place pile (2), installing a grouting hole sealing device (3) at the top of a pile core drilled hole (4), injecting high-pressure cement slurry into the concrete cast-in-place pile (2) from a grouting opening (1), and curing the pile bottom sediment. According to the method, the concrete cast-in-place pile is drilled so that the concrete cast-in-place pile can be repaired without damaging an original concrete cast-in-place pile, the original concrete cast-in-place pile fully plays a role, and compared with other pile bottom sediment processing methods, the method is more convenient to operate, shorter in construction time and lower in cost.

Description

technical field [0001] The invention belongs to the technical field of concrete pouring pile construction in geotechnical engineering, and in particular relates to a method for processing sediment at the bottom of concrete pouring piles. Background technique [0002] Concrete pouring pile is the most common method in pile foundation construction in my country. Due to the limitation of stratum conditions and construction methods, sediment at the bottom of the pile will inevitably be generated during the construction of concrete pouring pile in many cases. Some pile bottom sediments can be found and treated before pouring, but there are still some pile bottom sediments that are only discovered when the piles are inspected. This kind of pile bottom sediments after pile formation is not easy to handle. The thick sediment at the bottom of the pile will directly affect the quality of the pile foundation, reduce the bearing capacity of the single pile, and increase the settlement d...

AI Technical Summary

Problems solved by technology

Some pile bottom sediments can be found and treated before pouring, but there are still some pile bottom sediments that are not discovered until the pile is inspected. This kind of pile bottom sediment is not easy to deal with

Thick sediment at the bottom of the pile will directly affect the quality of the pile foundation, reduce the bearing capacity of the single pile, and increase the settlement displacement of the pile body

[0003] Conventional treatment methods are pile filling and adding piles. These methods generally need to destroy the original concrete pouring piles after detecting the sediment at the bottom of the pile in order to treat the sediment at the bottom of the pile well, which will cause huge losses in cost and waste construction time.
