晉城鋼波紋涵管的開槽回填方法介紹
在山(shan)區修建高(gao)速公路(lu),為(wei)達到(dao)終的(de)設計要求,深挖高(gao)填(tian)這種情(qing)況經(jing)常能(neng)遇到(dao),因此產生的(de)高(gao)填(tian)方路(lu)堤下的(de)涵(han)(han)洞工程越來越多。以前,高(gao)填(tian)方涵(han)(han)洞一般為(wei)鋼筋混凝土拱涵(han)(han)或蓋板涵(han)(han),而地基的(de)不均勻沉(chen)降導致涵(han)(han)洞的(de)開(kai)裂或拱圈的(de)開(kai)裂與塌陷,進(jin)一步引起(qi)路(lu)面的(de)沉(chen)降破壞,從而影......更(geng)多
