在管线制约下运用明挖改暗挖确保效益的分析

Analysis on applying opencut-underground excavation conversion for ensuring the benefit under the pipeline conditioning

针对深圳某人行地道3号4、号出入口施工过程中管线改迁制约,严重影响工期,对施工方案进行了优化,通过各方面经济比选,将明挖改为暗挖施工,避免了管线改迁对工期的影响,同时节省了改迁的费用。

In light of the pipeline alteration in the construction process of the Shenzhen pedestrian underpass No.3 and No.4 exit and entrance,the construction duration is seriously influenced.This paper optimizes the construction scheme.Through various economic comparison and selection,it changes opencut into underground excavation.As a result,it avoids the influence of pipeline alteration for the construction duration,and saves the alteration cost too.
