在锤击法打钢筋混凝土方桩施工中,常因地质条件变化、桩制作及打桩操作等因素造成桩顶碎裂,钢筋变曲变形以致无法继续锤击沉桩。此时,如桩尚未进入持力层或不满足贯入度要求,往往需要在附近补打一根桩,损失很大。我们试用硫磺胶泥加钢套箍修补碎桩顶,成功率为80%,收到了较好的效果。 In the construction of reinforced concrete square piles by hammering method, the top of the pile is often fragmented due to changes in geological conditions, pile making and piling operations, and the steel bar deforms so that it cannot continue to hammer the pile. At this time, if the pile has not entered the bearing layer or does not meet the penetration requirement, it is often necessary to make up a nearby pile and the loss will be large. We tested the top of the pile with sulphur cement and steel cuffs, and the success rate was 80%. We received good results.
