Reinforcing device and reinforcing construction method for prestressed hollow slab bridge
The invention relates to the technical field of bridge construction, and provides a prestressed hollow slab bridge reinforcing device which comprises a first steel structure plate and a second steel structure plate which are fixed to the belly portions of the two sides of a hollow slab, a plurality of first abutting pieces are arranged on the side face of the first steel structure plate, and the outer side faces of the first abutting pieces are arranged in an arc shape. A second abutting piece is arranged on the side face of the second steel structure plate, and the outer side face of the second abutting piece is in an arc shape. In the fixed state, the first abutting pieces and the second abutting pieces are alternately arranged in the vertical direction to jointly form a reinforcing structure, and the arc faces of the first abutting pieces on the hollow slabs and the arc faces of the second abutting pieces on the adjacent hollow slabs abut against each other for limiting. The reinforcing device further comprises steel strands penetrating through the hollow slabs, and the two ends of each steel strand are fixedly arranged and are in a tightened state all the time. On the basis, the structural strength of the hinge joint concrete between the two hollow slabs can be improved, and the possibility that the hinge joint concrete forms cracks and the bottom of a bridge cracks is reduced.
本申请涉及桥梁施工技术领域，提供了一种预应力空心板桥的加固装置，包括固定于空心板两侧腹部的第一钢构板和第二钢构板，第一钢构板的侧面设有多个第一抵接件，且第一抵接件的外侧面呈弧形设置，第二钢构板的侧面设有第二抵接件，且第二抵接件的外侧面呈弧形设置；在固定状态下，各个第一抵接件与各个第二抵接件沿竖向交替设置、共同形成加固结构，且空心板上第一抵接件的弧面与相邻空心板上第二抵接件的弧面相互抵接限位；加固装置还包括穿设于各个空心板的钢绞线，钢绞线的两端固定设置，且始终处于紧绷状态。基于此，能够提高两个空心板之间铰缝混凝土的结构强度，降低铰缝混凝土形成裂缝以及桥梁底部出现开裂的可能。
