Corrugated steel plate arc arch bridge H-shaped steel truss arch reinforcing method
The invention discloses a corrugated steel plate arc arch bridge H-shaped steel truss arch reinforcing method, which relates to the technical field of traffic engineering construction, and comprises the following steps of: cold-bending and lengthening a plurality of sections of H-shaped steel to form a semi-arc H-shaped steel truss arch; an H-shaped steel truss arch is lined in a trough in the middle of each annular plate width of the corrugated steel plate arc arch, and two edges of an upper flange of the H-shaped steel truss arch are in complete contact with two edges of the trough on the inner side of the corrugated steel plate arc arch; a hard rubber pad is adhered to a gap formed by the contact between the upper flange of each H-shaped steel truss arch and the wave trough on the inner side of the corrugated steel plate arc arch bridge; a liner steel plate is arranged on an arch seat of the corrugated steel plate arc arch at an arch foot of the H-shaped steel truss arch, and the arch foot of the H-shaped steel truss arch is supported on the liner steel plate; steel bar connecting bands are arranged on the cross sections of the arch top, the arch shoulders and the arch feet of the H-shaped steel truss arch in the transverse corrugation direction respectively, and the multiple H-shaped steel truss arches under the arch of the corrugated steel plate arc arch bridge are connected into a whole. The H-shaped steel is lined in the corrugated steel plate arc arch bridge to form the steel truss arch, the corrugated steel arc arch bridge is reinforced, the corrugated steel arc arch bridge is not prone to deformation when being extruded in the radial direction, the load bearing capacity is maintained or improved, the service life of the corrugated steel plate arch bridge is prolonged, and the effect is good.
本发明公开了一种波纹钢板圆弧拱桥H型钢桁架拱加固方法，涉及交通工程施工技术领域，包括以下步骤：将多段H型钢冷弯并接长形成半圆弧形H型钢桁架拱；在所述波纹钢板圆弧拱的每个环向板宽的中间的波谷内安衬一道H型钢桁架拱，H型钢桁架拱的上翼缘的两个边缘与波纹钢板圆弧拱内侧波谷两边完全接触；在每一道H型钢桁架拱的上翼缘与波纹钢板圆弧拱桥内侧的波谷接触形成的空隙间粘贴硬质橡胶垫；在所述H型钢桁架拱的拱脚处的波纹钢板圆弧拱拱座上设置衬垫钢板，将所述H型钢桁架拱的拱脚支撑到衬垫钢板上；在所述H型钢桁架拱的拱顶、拱肩、拱脚的横断面处，分别沿横波纹向设置一根钢条连接带，将波纹钢板圆弧拱桥的拱下多道H型钢桁架拱连成一体。本发明通过H型钢内衬于波纹钢板圆弧拱桥内形成钢桁架拱，对波纹钢圆弧拱桥进行加固，使其在受到径向挤压时不容易产生形变，并维持或提高荷载承受能力，延长波纹钢板拱桥使用寿命，效果良好。
