Efficient construction method for fabricated pier
The invention relates to an efficient construction method for a fabricated pier. The method mainly comprises the following steps that S1, pile foundation pouring, pier prefabrication and bent cap prefabrication, wherein a pile foundation is cast in place, and a pier and a bent cap are both prefabricated and formed in a prefabrication factory; S2, the transportation of the bridge pier and the bentcap; S3, the installation of the pier and the pile foundation, wherein firstly, positioning marks are made on the pier top and the pier bottom of the prefabricated pier, then an adjusting device is installed, the adjusting device is used for finely adjusting the position of the pier; a pier stud is hoisted, the pier is inserted into a second corrugated square tube of the pile foundation, and a gapis grouted between the pier and a bearing platform; and S4, the installation of the bridge pier and the bent cap, wherein a mortar cushion layer is laid on the top of the bridge pier, a cover plate is hoisted on the bridge pier, the cover plate descends after an assembly corrugated pipe embedded in the bent cap is aligned with pier stud embedded steel bars, and then cement grouting materials arepoured into the assembly corrugated pipe. The method has the effect of shortening the pier construction period.
本申请涉及一种装配式桥墩的高效施工方法，其主要包括以下步骤：步骤S1：桩基浇筑、桥墩预制和盖梁预制，其中桩基为现浇，桥墩和盖梁均在预制厂内预制成型；步骤S2：桥墩以及盖梁的运输；步骤S3：桥墩与桩基的安装，首先在预制桥墩的墩顶和墩底做好定位标记；接着安装调节装置，调节装置用于对桥墩的位置进行微调；然后吊装墩柱，将桥墩插接于桩基的第二波纹方管内，然后向桥墩与承台间缝隙灌浆；步骤S4：桥墩和盖梁的安装，在桥墩顶部铺设砂浆垫层，然后将盖板吊装于桥墩上，盖梁预埋的装配波纹管对准墩柱预埋钢筋后使盖板下放，然后向装配波纹管内灌注水泥灌浆料；本申请具有缩短桥墩施工周期的效果。
