存放鋼波紋管涵的場所應(ying)該平坦、遠離熱源,堆(dui)(dui)積(ji)(ji)時(shi),兩側用木(mu)楔和(he)(he)木(mu)板擋住(zhu),避免滑動;管(guan)材(cai)堆(dui)(dui)積(ji)(ji)高(gao)度要(yao)嚴厲依照CJ/T270-2007的要(yao)求(qiu)履行,不得超越3米(mi);不同直徑(jing)與不同環(huan)剛度等級的管(guan)材(cai)宜分類堆(dui)(dui)積(ji)(ji);假如長期堆(dui)(dui)積(ji)(ji)的話,為防(fang)止陽光直射和(he)(he)暴曬應(ying)遮(zhe)蓋好;橡膠(jiao)套、螺栓、不銹鋼(gang)套等宜放在倉庫存貯;在管(guan)道安裝(zhuang)現場,管(guan)材(cai)堆(dui)(dui)積(ji)(ji)應(ying)防(fang)止阻礙交(jiao)通。
鋼(gang)(gang)波(bo)紋(wen)管(guan)(guan)(guan)涵裝卸(xie)時(shi),嚴(yan)防管(guan)(guan)(guan)材(cai)(cai)拋落、相(xiang)互撞擊;小口徑(jing)、較輕管(guan)(guan)(guan)材(cai)(cai)可人(ren)工(gong)裝卸(xie),大口徑(jing)、重管(guan)(guan)(guan)材(cai)(cai)應(ying)(ying)選用(yong)機械吊(diao)裝;裝卸(xie)時(shi)要(yao)選用(yong)柔性軟(ruan)質(zhi)的(de)、較寬(kuan)的(de)尼(ni)龍吊(diao)帶(dai)或繩作為(wei)吊(diao)索,不得用(yong)鋼(gang)(gang)絲繩或鐵鏈直(zhi)接接觸吊(diao)裝管(guan)(guan)(guan)材(cai)(cai);管(guan)(guan)(guan)材(cai)(cai)的(de)起吊(diao)宜選用(yong)兩個吊(diao)點起吊(diao),禁止穿心吊(diao),吊(diao)點距離應(ying)(ying)符合的(de)要(yao)求。
When loading and unloading steel corrugated pipe culvert, it is strictly prevented from dropping and colliding with each other; Small diameter and light pipe can be loaded and unloaded manually, and large diameter and heavy pipe shall be hoisted mechanically; Flexible soft and wide nylon sling or rope shall be used as sling during loading and unloading, and steel wire rope or iron chain shall not be used to directly contact the hoisting pipe; Two lifting points shall be selected for pipe lifting, and it is forbidden to cross the center lifting. The distance of lifting points shall meet the requirements.
即管(guan)(guan)材(cai)(cai)上(shang)兩吊點應在(zai)距離管(guan)(guan)兩端約1/4管(guan)(guan)長處;移動(dong)(dong)或(huo)裝卸管(guan)(guan)材(cai)(cai)時(shi)不得形(xing)成其(qi)它管(guan)(guan)材(cai)(cai)移位或(huo)滾動(dong)(dong)。由于鋼波紋管(guan)(guan)涵結構中空,在(zai)堅持(chi)剛度(du)的前提下,節省(sheng)質料(liao)。相同直徑(jing)下,單位長度(du)重(zhong)量是水泥(ni)管(guan)(guan)重(zhong)量的1/8,施(shi)工(gong)便(bian)利,不需(xu)要大型(xing)安裝設備,減輕了(le)(le)勞動(dong)(dong)強度(du),縮(suo)短了(le)(le)施(shi)工(gong)工(gong)期。
不被污水、廢水及化學藥品(pin)腐(fu)蝕,不被土壤中(zhong)腐(fu)爛(lan)的物質腐(fu)蝕。管(guan)材質料價格低(di),施(shi)工、管(guan)理(li)、維護費用(yong)低(di)。管(guan)壁為“工”字結構,耐沖擊(ji),高剛性(xing);中(zhong)空(kong)壁纏繞管(guan)屬柔性(xing)管(guan),延伸性(xing)好,地(di)基下沉管(guan)材也不會決(jue)裂。
鋼波紋管(guan)(guan)涵(han)由所以柔性管(guan)(guan)道(dao)(dao),與(yu)傳統(tong)的(de)(de)管(guan)(guan)道(dao)(dao)施工(gong)方法(fa)和要(yao)求有所不(bu)同,在工(gong)程中(zhong)選(xuan)(xuan)用了管(guan)(guan)土(tu)共同作用的(de)(de)原(yuan)理,管(guan)(guan)道(dao)(dao)施工(gong)時開槽(cao)、敷設、回填等應嚴厲依照工(gong)程規范(fan)履行,應加強施工(gong)規范(fan)性的(de)(de)監管(guan)(guan),避免施工(gong)隨(sui)意,對工(gong)程質(zhi)量形成(cheng)影響(xiang)。在選(xuan)(xuan)購時,不(bu)要(yao)一味地(di)要(yao)求成(cheng)本低、價格低,在挑選(xuan)(xuan)鋼波紋管(guan)(guan)涵(han)時,應該多比(bi)較幾個,挑選(xuan)(xuan)諾言好(hao)的(de)(de),避免對工(gong)程工(gong)期形成(cheng)影響(xiang)。
