The scale of application of steel corrugated Guanhan (1) The metal corrugated pipe culvert is a flexible layout. In the layout, the corrugated pipe has an outstanding and extraordinary property of lateral repayment displacement. It can fully display the common local area with strong tensile and variable resistance functions. Has a large anti-deformation and anti-sedimentation experience, especially suitable for soft soil, bulging soil, wet LOESS and other foundation bearing capacity of the basin area and earthquake-pron模板厚度1cm,圆弧半径根据每个涵洞直径调整,弦高30cm三块,一块安装中间,另两块边板据外侧距离5cm,用来灌注砂浆,用方木定制成圆弧型,在用方木加固,在进行安装。 2、下半圆水泥砂浆施工,先施工下半圆底部部分,后施工两侧,待底部砂浆强度满足要求后再施工两侧,两侧施工时使用圆弧模板要对称施工,为保证砂浆厚度及施工质量模板与钢波纹管中间放置直径8mm螺旋筋,每平方不少于4个,施工分段进行6米设置一道伸缩缝,缝宽1cm,缝内填满沥青麻絮,施工下一段时注意处理接缝处松散砂浆,安装模板前涂抹相同标号水泥浆。 3、上半圆施工,分三次施工,先施工两侧后施工**部,沿两侧水平螺栓向上呈30度布置一根直径16钢筋增加钢丝网的钢度及复合型砂浆整体性,圆弧共布置5根。与螺栓位置相同部位在螺栓用铁丝固定,在两螺栓中间
