公路鋼(gang)波紋管(guan)用(yong)鋼(gang)(gang)筋混凝(ning)土(tu)代替涵(han)洞施(shi)工(gong),有助(zhu)于(yu)處理北方寒冷(leng)區(qu)域(yu)冬天管(guan)涵(han)混凝(ning)土(tu)結構破壞問題,適(shi)用(yong)于(yu)高原區(qu)域(yu)。楔形(xing)回(hui)填(tian)土(tu)不致(zhi)密(mi),導(dao)致(zhi)金屬(shu)鋼(gang)(gang)波紋管(guan)底部變(bian)(bian)平。公路鋼(gang)(gang)波紋管(guan)介紹,造成回(hui)填(tian)土(tu)變(bian)(bian)形(xing)的情況有幾種,即:鋼(gang)(gang)波紋管(guan)兩邊(bian)回(hui)填(tian)土(tu)不對稱(cheng)導(dao)致(zhi)鴨蛋(dan)變(bian)(bian)圓,嚴峻導(dao)致(zhi)塌陷。

環壓(ya)(ya)理論以為:在深埋的(de)地(di)下圓弧結(jie)構(gou)中,結(jie)構(gou)周圍土(tu)(tu)(tu)壓(ya)(ya)力(li)散(san)布的(de)不均勻性對(dui)管壁推力(li)的(de)大(da)小和散(san)布的(de)影響很小。關于柔性的(de)波紋鋼埋置式(shi)結(jie)構(gou),豎向荷載(zai)(恒(heng)載(zai)+活載(zai))使管壁產生變(bian)形(xing),擠壓(ya)(ya)兩邊土(tu)(tu)(tu)體,回填土(tu)(tu)(tu)體遭到擠壓(ya)(ya)后形(xing)成被動土(tu)(tu)(tu)壓(ya)(ya)力(li)。
跟著變形加(jia)大(da),土(tu)體與管(guan)壁承擔的荷載重新散布,使管(guan)壁周圍的土(tu)壓力趨于均(jun)勻環(huan)壓狀況。 擁(yong)有十分(fen)(fen)好(hao)的經(jing)濟特性,它(ta)的連(lian)接方法(fa)是(shi)十分(fen)(fen)便利的,可以很大(da)程(cheng)度上(shang)減(jian)縮工期,并且(qie)它(ta)的重量十分(fen)(fen)的輕,所以運輸(shu)也(ye)愈(yu)加(jia)的快捷(jie),再加(jia)上(shang)根底施(shi)工量十分(fen)(fen)的小,排水(shui)管(guan)道工程(cheng)的造價也(ye)會相對的減(jian)低。
With the increase of deformation, the load borne by the soil and the pipe wall is redistributed, so that the earth pressure around the pipe wall tends to be uniform. With very good economic characteristics, its connection method is very convenient, which can greatly reduce the construction period, and its weight is very light, so the transportation is faster and faster. In addition, the basic construction quantity is very small, and the cost of drainage pipeline project will be relatively reduced.

舉例(li)來(lai)說和直徑(jing)為600毫(hao)米(mi)的(de)波(bo)(bo)紋管(guan)以及水泥管(guan)的(de)建造(zao)本(ben)錢(qian)比較,自給式金(jin)屬鋼波(bo)(bo)紋管(guan)鍍鋅波(bo)(bo)紋鋼管(guan)的(de),建造(zao)本(ben)錢(qian)只需(xu)要水泥管(guan)建造(zao)本(ben)錢(qian)的(de)百分(fen)之九十左右,如果在一(yi)些交通不是很便利的(de)地(di)方進(jin)行施工的(de)時(shi)分(fen),也可以進(jin)行手動完結(jie),這樣就節省了叉車起重機和其他一(yi)些設備(bei)的(de)運作本(ben)錢(qian)。
50cm金屬鋼波紋管管體兩邊回填資料不符合要求,它應該用沙質資料填充。但是,當建筑中填充有黃土、脹大土等資料時,與水觸摸會變軟,沒有承載力,導致管體橫向變形過大。因為規劃出產標準化,規劃簡略,出產不受環境影響,工廠會集出產,出產周期短,適用于質量要求高,工期緊的工程項目。//hanihanbj.com/
