Bridge support crossing navigation inland river, using method of bridge support and bridge dismantling and building method
The invention discloses a navigation-crossing inland river bridge support, a using method thereof and a bridge demolition and construction method, the bridge support is located under an old bridge, the bridge support comprises a lower-layer support, the bottom end of the lower-layer support is located in a riverbed, and the top end of the lower-layer support extends out of an inland river water line; the lower-layer support is suitable for being installed below the old bridge when the old bridge is dismantled so as to be matched with the upper-layer support to support the old bridge, and the lower-layer support is suitable for building a new bridge on the upper portion of the lower-layer support after the old bridge is dismantled; the upper-layer bracket is detachably arranged above the lower-layer bracket; the upper-layer support is suitable for being installed above the lower-layer support when the old bridge is dismantled, and the upper-layer support is suitable for being dismantled after the old bridge is dismantled. The method can be used for dismantling an old bridge and building a new bridge, the lower-layer support meets the navigation requirement, the upper-layer support is erected on the basis of the lower-layer support for dismantling the old bridge, the upper-layer support is dismantled after the old bridge is dismantled, the disc buckle support is directly erected on the lower-layer support, the bridge is newly built, the support dismantling and rebuilding cost is saved, and the construction period is shortened.
本发明公开了一种跨通航内河桥梁支架及其使用方法、桥梁拆除搭建方法，桥梁支架位于旧桥正下方，桥梁支架包括：下层支架，底端定位于河床内，顶端从内河水位线伸出；下层支架适于在旧桥进行拆除时安装至旧桥下方，以与上层支架配合来对旧桥进行支撑，且下层支架适于在旧桥拆除后在其上部搭建新桥；上层支架，可拆卸设置于下层支架的上方；上层支架适于在旧桥进行拆除时安装至下层支架的上方，且上层支架适于在旧桥拆除后进行拆除。本发明可用于旧桥拆除和新桥搭建，下层支架满足通航需求，在下层支架的基础上搭设上层支架进行旧桥拆除，旧桥拆除后将上层支架拆除，在下层支架上直接搭设盘扣支架并新建桥梁，节约了支架拆除和重新搭建成本和工期。
