鋼波紋管卻不(bu)再收縮到原(yuan)來長度，這(zhe)種變(bian)型收叫做范性變(bian)型。由(you)彈性變(bian)型點轉(zhuan)變(bian)為范性變(bian)型的(de)時間，叫做屈撓點，其代表(biao)符(fu)號(hao)是σb，單位是MPa或N平方(fang)毫(hao)米。對于鋼(gang)絞(jiao)(jiao)線(xian)(xian)的(de)保護方(fang)法：進到現場的(de)鋼(gang)絞(jiao)(jiao)線(xian)(xian)要嚴(yan)峻掩蓋，避免雨淋，地上要墊方(fang)木以與地上隔(ge)脫(tuo)離，鋼(gang)絞(jiao)(jiao)線(xian)(xian)要先(xian)參(can)與先(xian)用，后參(can)與后用，不(bu)行保存時間太長。

抗張強度(du)假如涵洞規劃得太(tai)(tai)小和(he)太(tai)(tai)挨近于地表(biao)特別是(shi)在暴露的(de)(de)當地，并且水流速度(du)緩慢，則在北部(bu)地區的(de)(de)冬天容易(yi)凍(dong)結，后還(huan)要堵(du)塞。這可以得到彌補(bu)，方法所以添(tian)加涵洞的(de)(de)斜度(du)，選用無底的(de)(de)木制涵洞或在寒冷(leng)時節挨近時，把(ba)涵洞進(jin)口端用軟樹技鋪蓋。

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/
