公路工程道路素混凝土桩施工质量控制

Quality Control of Plain Concrete Pile Construction in Highway Engineering

采用素混凝土桩进行地基处理可有效提升地基的荷载能力,且在与桩周土体共同形变作用下,可以避免地基出现沉降的情况,应用效果十分显著。先对素混凝土桩施工特点及工艺作简要介绍,进而重点从试桩、混凝土质量、成桩、断桩及挤土效应等方面出发,提出公路工程道路素混凝土桩的施工质量控制要点,可为类似工程提供参考。

Using plain concrete pile for foundation treatment can effectively improve the load capacity of the foundation, and under the joint deformation with the soil around the pile, the settlement of the foundation can be avoided, which shows very significant application effect. This paper briefly introduces the construction characteristics and technology of plain concrete pile, and then puts forward the construction quality control points of plain concrete pile in highway engineering from the aspects of pile test, concrete quality, pile-forming, pile-breaking and soil-squeezing effect, which can provide reference for similar projects.
