Construction method of high-fill ultra-long fragmented assembled steel corrugated pipe culvert
The invention discloses a construction method of a high-fill ultra-long fragmented assembled steel corrugated pipe culvert. The construction method comprises the following steps: surveying and setting out; excavating a foundation pit; bearing capacity detection; construction of a culvert foundation gravel layer; carrying out secondary bearing capacity detection; carrying out secondary surveying and lofting; mounting the steel corrugated pipe; sealing and anti-corrosion treatment; backfilling a culvert back; converting a working surface; culvert entrance and exit construction. By means of framing construction and installation of the steel corrugated pipe pieces from the middle to the two sides, the overall construction efficiency is improved; the bearing capacity of the foundation pit is ensured to meet the design requirement through multiple times of bearing capacity detection and staking-out survey procedures, and accurate positions and sizes are provided for framing construction of the pipe culvert; by arranging the positioning steel bar piles and the cement bolsters, the corrugated pipes are prevented from shifting in the construction process, and the bearing capacity and stability of the culvert are improved; by means of the reasonable steel corrugated pipe piece splicing process, flat foaming sealing strips are additionally arranged at the joints between the steel corrugated pipe pieces, and bolts and connecting seams are sealed through hot melting asphalt, so that corrosion and water seepage are avoided.
本发明公开了一种高填方超长分片拼装钢波纹管涵洞施工方法，包括：测量放线；基坑开挖；承载力检测；涵基砂砾层施工；二次承载力检测；二次测量放样；钢波纹管安装；密封防腐处理；涵背回填；转换工作面；涵洞进出口施工。通过分幅施工和从中间向两边安装钢波纹管片的方式，提高整体施工效率；通过多次承载力检测和测量放样工序，确保基坑的承载能力符合设计要求，并为管涵分幅施工提供准确的位置和尺寸；通过设置定位钢筋桩和水泥垫枕，防止波纹管在施工过程中发生移位，提高涵洞的承载能力和稳定性；通过合理的钢波纹管片拼装工艺，在钢波纹管片之间接口处增加平板发泡密封条，并采用热熔沥青对螺栓和连接缝进行密封处理，避免锈蚀和渗水。
