Bridge foundation construction method for old city reconstruction
The invention provides a bridge foundation construction method for old city reconstruction. The method comprises the following steps that S1, earthwork excavating and hoisting are carried out, specifically, a pile foundation space used for embedding a bridge foundation is excavated in the ground of an old urban area, the earthwork is hoisted out from inside to outside, the earthwork cannot be normally hoisted due to the fact that an anchor cable is embedded in the lower part of the old urban area, and when a pile foundation is excavated, a person is additionally arranged to fasten a safety belt and stands at the position of the anchor cable to hold a soil frame loaded with the earthwork to assist in hoisting out the excavated earthwork, so that the soil frame penetrates through the side ofthe anchor cable until the earthwork is smoothly hoisted; S2, a steel casing is installed, specifically, the steel casing is divided into a plurality of blocks to be manufactured and assembled in a pile hole, and the influence on the anchor cable in a pile is avoided; S3, a reinforcement cage is mounted; and S4, concrete pile foundations are poured, under the condition that houses exist around the high slope, when a highway bridge foundation is built, the technical problem that the retaining wall anchor cable and retaining wall lattice beams collide with the pile foundation can be solved, andthe construction efficiency and the construction quality of the bridge foundation are guaranteed.
本发明提供了一种用于旧城改造的桥梁基础施工方法，包括以下步骤：S1、土石方开挖、吊运，在旧城区的地面开挖用于埋设桥梁基础的桩基空间，并将土石方从里往外吊运出来，由于旧城区下方埋藏有锚索的原因导致无法正常吊起土石方，在桩基开挖期间，增加一个人系好安全带，站在锚索位置扶着装有土石方的土框，协助吊出开挖的土石方，让土框从锚索旁边穿过直到顺利吊起土石方；S2、安装钢护筒，将一个刚护筒分成多块制作，在桩孔内进行拼装，避开对桩内锚索的影响；S3、安装钢筋笼；S4、浇筑混凝土桩基，在高边坡四周已有房屋的情况下，修建公路桥梁基础时，本申请可以解决挡墙锚索和挡墙格梁与桩基础相碰撞的技术问题，保障桥梁基础的施工效率和施工质量。
