鋼波紋管涵洞有哪些施工要求?

在(zai)公(gong)路(lu)涵(han)(han)洞中對(dui)其(qi)破(po)壞(huai)更(geng)大(da)的(de)(de)因素就是(shi)沉降不平(ping)均(jun),公(gong)路(lu)涵(han)(han)洞施工(gong)(gong)中,其(qi)使(shi)用材料(liao)與(yu)(yu)工(gong)(gong)程結構(gou)具(ju)(ju)有一定(ding)的(de)(de)關(guan)系。通常情況下,施工(gong)(gong)職員都會使(shi)用柔性、高強度的(de)(de)鋼(gang)(gang)波紋(wen)管(guan)涵(han)(han)洞,這種材料(liao)不僅具(ju)(ju)有一定(ding)的(de)(de)適應(ying)地基與(yu)(yu)基礎(chu)變形的(de)(de)能力,而(er)且對(dui)于(yu)解(jie)決因地基基礎(chu)不平(ping)均(jun)沉降導(dao)致的(de)(de)涵(han)(han)洞破(po)壞(huai)題目也(ye)具(ju)(ju)有重要(yao)作(zuo)用,鋼(gang)(gang)波紋(wen)管(guan)涵(han)(han)洞因其(qi)軸向(xiang)波紋(wen)的(de)(de)存在(zai)使(shi)之(zhi)具(ju)(ju)有良(liang)好的(de)(de)受力能力。鋼(gang)(gang)波紋(wen)管(guan)涵(han)(han)洞的(de)(de)軸向(xiang)和(he)徑向(xiang)同(tong)時分布(bu)可以在(zai)一定(ding)程度上(shang)(shang)將荷載(zai)的(de)(de)應(ying)力進(jin)行有效(xiao)分散(san),從(cong)而(er)更(geng)好地施展鋼(gang)(gang)結構(gou)的(de)(de)上(shang)(shang)風(feng)。利用鋼(gang)(gang)波紋(wen)管(guan)結構(gou)可以有效(xiao)修筑不良(liang)工(gong)(gong)程巖(yan)(yan)土(tu)地區的(de)(de)涵(han)(han)洞,如:多年(nian)凍土(tu)、軟(ruan)土(tu)、膨脹土(tu)、濕陷性黃土(tu)等(deng)不良(liang)工(gong)(gong)程巖(yan)(yan)土(tu)地區。鋼(gang)(gang)波紋(wen)管(guan)因其(qi)明顯的(de)(de)上(shang)(shang)風(feng)也(ye)使(shi)其(qi)具(ju)(ju)有更(geng)廣闊的(de)(de)應(ying)用遠(yuan)景。 

 鋼(gang)波紋(wen)管(guan)作(zuo)為一(yi)種新型技(ji)術在(zai)公(gong)路涵洞(dong)工程施工中的(de)具(ju)有(you)很大的(de)上風(feng),鋼(gang)波紋(wen)管(guan)涵洞(dong)技(ji)術不僅具(ju)有(you)施工周期短、適(shi)應能力(li)強(qiang)、地基承(cheng)載力(li)要求(qiu)低的(de)特(te)(te)點(dian),而且(qie)具(ju)有(you)較強(qiang)的(de)耐性,可以(yi)(yi)大大減(jian)少施工的(de)時(shi)間,因而這種技(ji)術被運用。本文(wen)主要探討了鋼(gang)波紋(wen)管(guan)涵洞(dong)的(de)技(ji)術特(te)(te)點(dian)以(yi)(yi)及(ji)上風(feng)。

機能(neng)分析其主要(yao)機能(neng)上風表現(xian)在抗拉機能(neng)、抗沖擊韌(ren)性、耐(nai)疲憊性以及冷(leng)彎(wan)機能(neng)等(deng)幾個方面,沖擊韌(ren)性主要(yao)是指鋼材(cai)抵(di)擋沖擊荷載作(zuo)用的(de)(de)能(neng)力;耐(nai)疲憊性主要(yao)是指其在反復的(de)(de)交(jiao)變(bian)荷載作(zuo)用下為產生疲憊破(po)壞的(de)(de)更大應力;冷(leng)彎(wan)機能(neng)主要(yao)是指其在常溫狀態下承受彎(wan)曲變(bian)形的(de)(de)能(neng)力。
