山岭重丘区高速公路路基高效施工技术研究

Study on Efficient Construction Technology of Expressway Roadbed in Mountainous and Heavy Hill Areas

以广西某高速公路路基工程的施工为例,对影响路基施工的边坡施工平台技术和临时挡墙施工技术进行了深入探讨。本工程研究采用了一种新型的整体式可移动边坡施工平台和一种高效的阵列式斜拉桩挡墙,从研究目的、施工装置结构组成、施工工艺和功效对比分析等方面进行了专业的阐述。这两种施工技术的采用,明显加快了工程进度,节约了工期,提高了工程效率。此类施工技术在国内工程实例较少,具有一定的借鉴意义。

Taking the construction of a certain highway roadbed project in Guangxi as an example,this paper deeply explored the slope construction platform technology and temporary retaining wall construction technology that affect roadbed construction.This project research adopt a new type of integral movable slope construction platform and an efficient array type cable-stayed pile retaining wall.Then a detailed explanation was provided from the following aspects,including the research purpose,construction device structure composition,construction technology and efficacy comparison analysis.The adoption of these two construction techniques had significantly accelerated the progress of the project,saved the construction period,and improved the efficiency of the project.This type of construction technology has few engineering examples in China,which certains reference significance.
