鋼波紋涵管也叫波紋管涵，是指鋪埋在公路、鐵路路下的涵洞用的螺紋波紋管，它是由波形鋼板卷制成或用波形鋼片組拼成的圓形鋼結構管。金屬波紋管涵的波紋結構可使涵洞路面受力合理，荷載分布均勻，并具有一定的抗變形能力，能解決北方寒冷地區（霜凍）對橋梁和管涵砼結構的破壞問題；使路表面沒有伸縮縫，提高行車舒適性；有利于改善軟土地基結構與路堤交界處的“錯臺”現象，提高行車安全性。波紋管涵的工后營運、養護成本低，工程實際造價也低于同類跨徑的橋梁、涵洞。鋼波紋涵管進出口也可按照邊坡比例做成斜口，加工波紋管管徑范圍0．5～8 m，管壁厚度為3 mm～7 mm，能夠滿足填土0．5 ～40 m厚的需要。

Steel corrugated culvert pipe, also known as corrugated pipe culvert, refers to the threaded corrugated pipe used for culverts buried under highways and railways. It is a circular steel structural pipe made of corrugated steel plates or assembled with corrugated steel sheets. The corrugated structure of metal corrugated pipe culverts can make the road surface of the culvert stress reasonable, load distribution uniform, and have a certain degree of deformation resistance, which can solve the problem of damage to the concrete structure of bridges and pipe culverts in cold northern regions (frost); Make the road surface without expansion joints to improve driving comfort; Beneficial for improving the "staggered platform" phenomenon at the junction of soft soil foundation structure and embankment, and enhancing driving safety. The post construction operation and maintenance costs of corrugated pipe culverts are low, and the actual engineering cost is also lower than that of bridges and culverts with similar spans. The inlet and outlet of steel corrugated culvert pipes can also be made into inclined openings according to the slope ratio. The diameter range of processed corrugated pipes is 0.5-8m, and the wall thickness is 3-7mm, which can meet the needs of filling soil with a thickness of 0.5-40m.

在凍土環境下，鋼波紋管的施工需要特別注意確保管道的安全與穩定性。以下是一些建議的施工步驟和注意事項： 

基礎準備：首先，需要對施工區域進行詳細的地質勘察，了解凍土的分布、厚度和特性。根據勘察結果，制定合適的施工方案。在施工前，清理施工區域的雜物，確保施工場地平整。 

土壤處理：對于凍土區域，可以采取加熱、保溫等措施，降低凍土的影響。在必要時，可以對土壤進行改良，提高其承載力和穩定性。 

管道安裝：鋼波紋管的安裝應嚴格按照設計要求進行。在凍土環境下，應特別注意管道的保溫措施，防止管道因溫度變化而變形或破裂。同時，管道的連接應牢固可靠，防止漏水或滲漏。 

回填與壓實：管道安裝完成后，應及時進行回填。回填材料應選用符合要求的土壤或砂石，并逐層壓實，確保回填的密實度。在凍土環境下，應特別注意回填材料的保溫性能，防止凍脹對管道造成損害。 

排水措施：為防止凍土融化導致的積水問題，應在施工區域設置有效的排水系統，確保施工期間和后續使用過程中排水暢通。 

監測與維護：施工完成后，應定期對鋼波紋管進行檢查和維護，確保其正常運行。同時，應建立監測系統，對管道的變形、位移等情況進行實時監測，以便及時發現并處理潛在問題。 

總的來說，在凍土環境下進行鋼波紋管施工需要綜合考慮地質條件、保溫措施、排水系統等多個方面，確保施工質量和管道的安全穩定。
