桩基承台在沿河县城防护工程中的应用

Application of Pile Cap in Yanhe County Urben Protective Engineering

针对沿河县城防护工程高边坡及复杂的地质情况,为确保工程施工安全,加快施工进度,确定采用桩基承台施工方案,即采用人工挖孔桩,浇筑钢筋混凝土护壁,待孔深达到设计要求后,清孔,放置钢筋笼,浇筑桩身钢筋混凝土,再在桩上部浇筑钢筋混凝土梁板,利用该承台承受荷载,在承台上部修建浆砌石挡墙,从而达到保持边坡稳定的目的。文章主要阐述了沿河县城防护工程中桩基承台的运用。

In terms of high slope and complicated geological conditions of Yanhe County urban protective engineering,in order to guarantee construction safety and speed up the construction,pile cap construction method is determined,namely adopting the artificial dig hole pile,concrete wall,after meeting the design hole depth,conducting the hole cleaning,placing the reinforcement cage,pouring the pile of reinforced concrete,then pouring reinforced concrete beam and slab on the pile top. Using the cap to load bearing,masonry retaining wall is constructed on the upper part of the cap to keep the slope stability. This paper mainly describes the use of pile cap protection project in Yanhe County.
