Hollow slab bridge reinforcing and transforming method
The invention discloses a hollow slab bridge reinforcing and transforming method and relates to the field of bridge construction. The hollow slab bridge reinforcing and transforming method comprises the following steps that multiple pieces of first profile steel are connected to the bottom of a hollow slab bridge; a plurality of corrugated pipes are arranged between every two adjacent hollow slabs forming the hollow slab bridge; pouring above the hollow slab bridge and among the hollow slabs to obtain UHPC concrete layers, so that the UHPC concrete layers wrap the corrugated pipes and are connected with the hollow slab bridge into a whole; and a prestressed steel bar penetrates through the corrugated pipes and then penetrates through the first profile steel, a prestressed fixing end anchorage device and a prestressed tensioning end anchorage device are installed at the two ends of the prestressed steel bar correspondingly for tensioning, and the prestressed tensioning end anchorage device is fixed. According to the hollow slab bridge reinforcing and transforming method, the UHPC concrete layer, the hollow slab bridge and the first profile steel are tensioned through the prestressed steel bars to form a stable and reliable overall structure, and the residual bearing capacity of the hollow slab is utilized to the maximum extent while the performance of the reinforcing structure is fully utilized.
一种空心板桥梁加固改造方法，涉及桥梁施工领域。空心板桥梁加固改造方法包括以下步骤：在空心板桥梁的底部连接多个第一型钢；在组成空心板桥梁的每两个相邻空心板之间设置多个波纹管；在空心板桥梁上方和各个空心板之间浇筑得到UHPC混凝土层，使UHPC混凝土层包裹波纹管并与空心板桥梁连接成一个整体；分别将预应力钢筋穿过各个波纹管后贯穿第一型钢，在预应力钢筋的两端分别安装预应力固定端锚具和预应力张拉端锚具进行张拉，固定预应力张拉端锚具。空心板桥梁加固改造方法使用预应力钢筋将UHPC混凝土层、空心板桥梁和第一型钢拉紧形成稳定可靠的整体结构，在充分利用加固结构的性能的同时最大化利用空心板剩余的承载能力。
