本文是从实践中总結出来的在营业綫上不間断行車修建小桥涵及大中桥墩桥台的施工方法,很有参考价值。但对T形桥台后牆部分,如加設一个排架,不仅有木桩穿过,間有横撑斜撑交叉,势必将后牆分为两段,对桥台整体性不利。对改建木桥,利用原有桩木穿越基础,当桩木拔除后,新旧混凝土粘結較差,同时,基础部分桩孔四周土壤坍落,增加基底应力。这种方法,在使用中还应进一步研究改进,使其更为完善。 This article is summarized from the practice of continuous business in the construction of small bridges and culvert bridges and bridge construction methods, is of great reference value. However, the T-shaped bridge abutment wall part, such as the addition of a rack, not only through the stakes, between the cross brace cross, is bound to the back wall is divided into two sections, the integrity of the abutment adverse. On the reconstructed wood bridge, the original pile wood is used to cross the foundation. When the pile wood is removed, the old and new concrete are poorly bonded together. At the same time, the soil around the pile hole of the foundation part collapses to increase the base stress. This method, in use, should be further studied and improved to make it more perfect.
