我处转战××线后,接受了35座大、中桥的施工任务,大多受水库水位控制,工期紧、任务重。广大职工,民兵遵照伟大领袖毛主席关于“精心设计,精心施工”的敎导,利用山坡旱桥的有利条件,将64个墩台明挖基础改为挖孔桩基础施工,共筑挖孔桩219根,总长1381.15米。减少了挖基土石方59018m~3,为原设计的44％,节省圬工4119m~3,为原设计的8.3％,增加钢材用量149.6吨,节约投资43万元,大大加快了工程的进展。一、应用情况 1. 挖孔桩基础首先是为了减少挖基土石方、方便施工而提出来的,在深埋基础中采用,收效十分显著。如××1#大桥南台,原设
I fought in XX line, accepted the 35 large and medium-bridge construction tasks, mostly by the reservoir water level control, tight schedule, heavy task. The broad masses of workers and militiamen follow the guidance of Chairman Mao, the great leader, on “well-designed and meticulously constructed” and make good use of the favorable conditions of the dry slopes of the slopes to change the basis of 64 piers and ceilings in digging into piles and construction of dug piles 219, the total length of 1381.15 meters. It reduces the excavation of 59018m ~ 3 of earthwork, 44% of the original design, saving labor 4119m ~ 3, 8.3% of the original design, increasing the amount of steel 149.6 tons, saving 430,000 yuan investment, greatly accelerating the progress of the project. First, the application of the situation 1. Digging pile foundation First, in order to reduce the foundation digging stone, to facilitate the construction and put forward in the deep foundation, the effect is very significant. Such as × × 1 # Bridge Nantai, the original design
