季冻区浅埋地基钢波纹管涵洞施工关键技术

Key Technology for Construction of Corrugated Steel Culvert with Shallow Foundation in Seasonally Frozen Regions

通过对大孔径钢波纹管涵洞在东北季节性冻土区进行适用性分析,结合鹤大高速吉林段季节性冻土区新修钢波纹管涵洞的施工经验,对施工中地基处理、钢波纹管拼装、防腐处理、回填材料的选择及压实进行分析,并对钢波纹管进行质量控制,形成施工质量控制指标,从而更好地指导季冻区大孔径钢波纹管的涵洞施工。

The applicability of large-diametered corrugated steel culvert in seasonally frozen regions in northeastern China was studied. Combined with the experience in corrugated steel culvert construction of Jilin section of Hegang Dalian expressway, foundation treatment, corrugated steel pipes assembling, corrosion resistance treatment, backfill materials selection and compaction were analyzed. Quality control of the corrugated steel pipes was conducted, and related indicators were acquired, which provides reference for the construction of large-diametered corrugated steel culvert in seasonally frozen regions.
