我局十处在桥梁基坑开挖中采用喷混凝土护壁获得成功,这在我局桥基施工中是一项首创的新方法,它既已用于深基坑,则在挖孔桩、锚固桩、隧道竖井等类似工程中均可考虑采用,对于加快施工速度,节约劳力和材料均有一定作用。以下提出几点粗浅的看法,供研究这个施工方法时参考。 一、十处的总结指出:根据地质及渗水情况,护壁厚度采用5~8厘米,少数采用3厘
I Bureau of the ten in the bridge foundation pit excavation using spray concrete retaining wall success, which in our bureau bridge construction is a pioneering new method, it has been used in deep foundation pit, digging in the pile, anchoring Piles, tunnels and other similar projects can be considered, for speeding up construction, labor-saving and materials have a certain role. Here are some superficial views for the study of this construction method for reference. First, the conclusion of ten pointed out: According to the geological and seepage conditions, the thickness of the protective wall 5 to 8 cm, a small number of 3%
