鋼波紋管由于其(qi)(qi)軸向(xiang)波紋(wen)的存在(zai),使(shi)得徑(jing)向(xiang)承載力大(da)大(da)提高，同時由于其(qi)(qi)軸向(xiang)波紋(wen)的存在(zai)，使(shi)其(qi)(qi)具(ju)有較好的橫向(xiang)變形補償特(te)性,因而具(ju)有較好的不均勻沉(chen)降(jiang)變形的適應能(neng)力。

關于鋼波紋管施工保障如何能做到更好

軟土地基(ji)的(de)(de)處(chu)理方案處(chu)理原則(ze)當(dang)涵管處(chu)于軟土地基(ji)上時，需對軟土路(lu)基(ji)進(jin)行處(chu)理，涵洞地基(ji)處(chu)理方法同該路(lu)段的(de)(de)路(lu)基(ji)處(chu)理方法，然后在其(qi)上填一層(ceng)大于80cm厚的(de)(de)優(you)質砂礫墊層(ceng)。

處(chu)理(li)(li)(li)措施根據軟基(ji)厚度及填(tian)土高(gao)度，確定(ding)處(chu)理(li)(li)(li)措施，當(dang)淤(yu)(yu)(yu)(yu)泥小于4米(mi)(mi)深時(shi)，采(cai)(cai)用清(qing)(qing)淤(yu)(yu)(yu)(yu)拋(pao)石(shi)處(chu)理(li)(li)(li)方法，一般(ban)(ban)清(qing)(qing)淤(yu)(yu)(yu)(yu)深度為(wei)(wei)1.5-2.5米(mi)(mi)，拋(pao)石(shi)厚度一般(ban)(ban)為(wei)(wei)1.5-2.5m,讓其(qi)(qi)(qi)穩定(ding)后，采(cai)(cai)用壓實(shi)機械(xie)壓實(shi)，在(zai)(zai)其(qi)(qi)(qi)鋪(pu)設(she)(she)不(bu)小于80厘(li)米(mi)(mi)的(de)碎石(shi)墊(dian)(dian)(dian)層。如果當(dang)淤(yu)(yu)(yu)(yu)泥4-6米(mi)(mi)深，填(tian)土超過10米(mi)(mi)，采(cai)(cai)用清(qing)(qing)淤(yu)(yu)(yu)(yu)拋(pao)石(shi)處(chu)理(li)(li)(li)方法，一般(ban)(ban)清(qing)(qing)淤(yu)(yu)(yu)(yu)深度為(wei)(wei)2-4米(mi)(mi)，拋(pao)石(shi)厚度一般(ban)(ban)為(wei)(wei)2-3m,讓其(qi)(qi)(qi)穩定(ding)后，采(cai)(cai)用壓實(shi)機械(xie)壓實(shi)，為(wei)(wei)保證基(ji)礎(chu)整體(ti)性，建議還要(yao)在(zai)(zai)80厘(li)米(mi)(mi)墊(dian)(dian)(dian)層中鋪(pu)設(she)(she)兩道土工(gong)格柵。當(dang)淤(yu)(yu)(yu)(yu)泥大于6米(mi)(mi)深時(shi)，采(cai)(cai)用 CFG基(ji)樁加固，然(ran)后在(zai)(zai)其(qi)(qi)(qi)上填(tian)一層大于80cm厚的(de)優質(zhi)砂(sha)礫墊(dian)(dian)(dian)層，并夯實(shi)緊密。

工(gong)(gong)(gong)程(cheng)開(kai)工(gong)(gong)(gong)前(qian)，對(dui)總體工(gong)(gong)(gong)程(cheng)進行(xing)質量(liang)(liang)策劃及質量(liang)(liang)計劃，對(dui)關鍵(jian)工(gong)(gong)(gong)序、重點及難點進行(xing)預控。做好技術交底工(gong)(gong)(gong)作，使操作人員(yuan)明確(que)施工(gong)(gong)(gong)方法、操作要點和質量(liang)(liang)標準(zhun)要求。

你知道鋼波紋管是如何進行施工保障的嗎？人員培訓。對特殊工種人員，堅持持證上崗;對未取證的人員進行培訓，經培訓后進行跟蹤考核。波形鋼(gang)管涵原(yuan)材料(liao)(liao)采購。在施(shi)(shi)工(gong)(gong)前對供(gong)方進(jin)行評價控(kong) 制(zhi)(zhi)，選擇合格(ge)有信(xin)譽的(de)供(gong)方。對施(shi)(shi)工(gong)(gong)使用的(de)原(yuan)材料(liao)(liao)， 按規定的(de)頻率(lv)進(jin)行抽(chou)撿，不合格(ge)的(de)材料(liao)(liao)堅決不用于 工(gong)(gong)程施(shi)(shi)工(gong)(gong)。嚴格(ge)控(kong)制(zhi)(zhi)施(shi)(shi)工(gong)(gong)質量。
