Distributed traction type culvert or tunnel reinforcing structure and construction method thereof
The invention relates to a distributed traction type culvert or tunnel reinforcing structure and a construction method thereof. The distributed traction type culvert or tunnel reinforcing structure comprises a plurality of corrugated steel reinforcing units, a guide rail and a traction device, wherein the guide rail is laid on an excavation bottom face in an existing culvert or tunnel, and the traction device is arranged at a tunnel exit and comprises a winch and a plurality of traction steel wire ropes; an end of the traction steel wire rope is provided with a drag hook which can be hooked with the corrugated steel reinforcing unit; the corrugated steel reinforcing unit is formed by sequentially connecting a plurality of corrugated steel plates, grouting holes are formed in the corrugated steel reinforcing unit, and flange plates are arranged at two ends of the corrugated steel reinforcing unit. The reinforcing structure is advantaged in that the modular O-shaped or n-shaped corrugated steel reinforcing units are adopted, so distributed reinforcement of culverts or tunnels with different reinforcement requirements can be completed; construction inconvenience caused by insufficient construction space of the culvert or the tunnel is greatly reduced, errors and defects of on-site assembly construction of the corrugated steel are reduced, the quality and efficiency of on-site construction are improved, and the strength of the repairing and reinforcing structure of the culvert or the tunnel is improved.
本发明涉及一种分布牵引式涵洞或隧道加固结构及其施工方法，包括若干波纹钢加固单元、导轨和牵引装置，所述导轨铺设于既有涵洞或隧道内部的开挖底面，所述牵引装置设置于隧道出口，包括卷扬机和多根牵引钢丝绳，牵引钢丝绳的端头设置拉钩可与波纹钢加固单元钩连；所述波纹钢加固单元由多片波纹钢板依次连接构成，波纹钢加固单元上设置有注浆孔，其两端设置有法兰盘；本发明采用模块化的“O”形或“Π”形的波纹钢加固单元可以完成对不同加固要求的涵洞或隧道的分布式加固；大大降低了因涵洞或隧道施工空间不足造成的施工不便，减少了波纹钢现场拼装施工的误差和缺陷，提高现场施工的质量和效率，提高了涵洞或隧道修复加固结构的强度。
