Temporary steel bridge system capable of keeping unobstructed
The temporary steel bridge system comprises a bridgehead guide slope, a supporting beam and a spanning beam, the supporting beam is installed on a bridge deck at the position of an old bridge abutment, and protruding limiting stop blocks are arranged at the two ends of the supporting beam; the supporting beam is provided with at least two reinforcing parts in the length direction of the supporting beam, and U-shaped bent bolts are embedded in the positions, below the reinforcing parts, of the supporting beam. The two ends of the bent bolt penetrate through the supporting beam; the bridgehead guide slopes are laid on the road surfaces at the two ends of the bridgehead, the lower ends of the inner side ends of the bridgehead guide slopes are provided with pressing grooves with the same appearance as the supporting beams, and the outer side ends of the supporting beams are embedded in the pressing grooves. The two ends of the spanning beam are erected on the supporting beams at the two bridge abutments and are connected with the inner side ends of the bridge head guide slopes in an attached mode. According to the method, the temporary partial load beam is laid on the original bridge, the old bridge is temporarily reinforced, the safety of overweight vehicle bridge crossing is guaranteed by applying the load reduction technology, the supporting parts are placed at the positions of the pier and the abutment of the old bridge, the main beam of the bridge bears all vehicle live loads, and the main beam of the old bridge is not affected by the vehicle live load effect.
本发明公开了一种保通钢便桥体系，包括桥头引坡、支撑梁和跨越梁，所述支撑梁安装在旧桥桥台处的桥面上，两端设有凸出的限位挡块；所述支撑梁沿其长度方向至少设有两处加强部，所述支撑梁在加强部下方预埋有U型弯螺栓；所述弯螺栓两端上穿支撑梁；所述桥头引坡铺设在桥头两端路面上，其内侧端下端设有与支撑梁外形相同的压槽，所述支撑梁的外侧端嵌设在压槽内；所述跨越梁两端架设在两桥台处的支撑梁上，并与桥头引坡的内侧端贴接。本发明通过在原桥上铺设临时性分载梁，对旧桥进行临时性加固，应用减载技术保障超重车辆过桥的安全，支撑部位放置在旧桥桥墩及桥台位置，便桥主梁承担全部汽车活载，旧桥主梁不受汽车活载效应。
