Construction method for pile group foundation of bridge in abrupt slope terrain
The invention discloses an abrupt slope terrain bridge pile group foundation construction method. The method comprises the steps that construction preparation work is conducted; excavating a foundation pit and designing a protection scheme; anti-slide pile and retaining protection construction; the step-shaped foundation construction platform is excavated and backfilled; conveying belt auxiliary deslagging equipment is installed; pile foundation construction; and bearing platform construction. The construction method mainly aims at construction of a bridge pile group foundation in the abrupt slope terrain, anti-slide piles are adopted as pit wall supports and protectors, filling and excavation are combined to construct a step-shaped construction platform, and a conveying belt assists in deslagging, so that the excavation volume of a foundation pit is reduced, the excavation height of a side slope is reduced, the construction risk is reduced, and the foundation construction time is shortened. The method has the following characteristics that the excavation volume of the foundation pit is small, damage to the surrounding natural environment is small, and green and low-carbon effects are achieved; the height of the foundation pit slope is greatly reduced, the foundation pit excavation work amount is reduced, the slope protection work amount of the slope foundation pit is reduced, the construction period is shortened, and the construction cost is reduced; as the height of the foundation pit slope is greatly reduced, disturbance to excavation of the foundation pit slope is small, and the construction risk is reduced.
本发明公开一种陡坡地形桥梁群桩基础施工工法，包括：施工准备工作；基坑开挖及防护方案设计；抗滑桩及支挡防护施工；开挖、回填台阶形基础施工平台；安装输送带辅助出渣设备；桩基施工；承台施工。本工法主要是针对陡坡地形桥梁群桩基础施工，采用抗滑桩作为坑壁支挡及防护，填挖结合构建台阶形施工平台，输送带辅助出渣，以减少基坑开挖量，减少边坡开挖高度，降低施工风险，缩短基础施工时间的一种施工方法，有以下特点：基坑开挖量少，对周边自然环境破坏小，绿色低碳；极大降低基坑边坡高度，减少基坑开挖工程量，减少边坡基坑边坡防护工程量，缩短施工周期，降低施工成本；因极大降低基坑边坡高度，对基坑边坡开挖扰动小，降低施工风险。
