鋼波紋管卻不再收(shou)縮到(dao)原來(lai)長度，這種變(bian)(bian)型(xing)收(shou)叫(jiao)做范性(xing)變(bian)(bian)型(xing)。由彈性(xing)變(bian)(bian)型(xing)點(dian)轉變(bian)(bian)為范性(xing)變(bian)(bian)型(xing)的時間(jian)，叫(jiao)做屈撓(nao)點(dian)，其代(dai)表符(fu)號是σb，單(dan)位(wei)是MPa或N平方(fang)毫米。對于鋼(gang)絞(jiao)線的保(bao)護方(fang)法：進(jin)到(dao)現場(chang)的鋼(gang)絞(jiao)線要嚴(yan)峻(jun)掩(yan)蓋(gai)，避免雨(yu)淋，地上要墊方(fang)木以與地上隔(ge)脫離(li)，鋼(gang)絞(jiao)線要先參與先用(yong)(yong)，后參與后用(yong)(yong)，不行保(bao)存時間(jian)太長。

抗張強度假如涵(han)(han)洞(dong)規劃得(de)太小(xiao)和太挨(ai)近于地表特別是(shi)在(zai)暴露(lu)的(de)當地，并且水流速度緩慢，則在(zai)北部(bu)地區的(de)冬天容(rong)易(yi)凍結(jie)，后還要堵塞。這可以得(de)到彌補，方法(fa)所(suo)以添加涵(han)(han)洞(dong)的(de)斜度，選用(yong)無底(di)的(de)木制涵(han)(han)洞(dong)或在(zai)寒冷時(shi)節挨(ai)近時(shi)，把涵(han)(han)洞(dong)進口(kou)端(duan)用(yong)軟(ruan)樹技鋪(pu)蓋。

Tensile strength if the culvert is planned to be too small and too close to the surface, especially in the exposed area, and the water flow speed is slow, it is easy to freeze in winter in the northern area and block later. This can be made up by adding the slope of the culvert, selecting the bottomless wooden culvert or covering the inlet end of the culvert with soft tree technology when approaching in cold season.

鋼波紋管

拆模時留心保護端頭處外漏的鋼波紋管。為了給圓形管拱或拱起金屬鋼波紋管而預備好一個滑潤床，要鋪上一層厚度10厘米左右的粗砂層或礫石層，該層的資料要求松懈些以便金屬鋼波紋管可以埋沒于該層中。該滑潤床應具有3-5%接連斜度，支承金屬鋼波紋管管道全長。回填土應按6英寸一層給予壓實以加固對涵洞的側向支持力。//hanihanbj.com/
