鋼波紋管由于(yu)其(qi)軸向波紋的(de)(de)存在,使得徑(jing)向承載力大大提(ti)高,同時由于(yu)其(qi)軸向波紋的(de)(de)存在,使其(qi)具(ju)有較好的(de)(de)橫向變(bian)(bian)形補償特性,因而具(ju)有較好的(de)(de)不均勻沉(chen)降(jiang)變(bian)(bian)形的(de)(de)適應能力。
關于鋼波紋管施工保障如何能做到更好
軟(ruan)土地(di)基(ji)的處(chu)(chu)理(li)方案處(chu)(chu)理(li)原則(ze)當涵管處(chu)(chu)于軟(ruan)土地(di)基(ji)上(shang)時,需對軟(ruan)土路基(ji)進行處(chu)(chu)理(li),涵洞地(di)基(ji)處(chu)(chu)理(li)方法同該路段的路基(ji)處(chu)(chu)理(li)方法,然后在(zai)其(qi)上(shang)填(tian)一層大于80cm厚的優質砂礫墊(dian)層。
處(chu)理(li)措施(shi)根據軟基(ji)厚度(du)及填(tian)土(tu)高度(du),確定處(chu)理(li)措施(shi),當淤(yu)泥小于4米(mi)(mi)深時,采(cai)用(yong)(yong)(yong)清淤(yu)拋石(shi)處(chu)理(li)方法(fa),一(yi)般(ban)(ban)(ban)清淤(yu)深度(du)為(wei)1.5-2.5米(mi)(mi),拋石(shi)厚度(du)一(yi)般(ban)(ban)(ban)為(wei)1.5-2.5m,讓(rang)其(qi)穩定后,采(cai)用(yong)(yong)(yong)壓實機械壓實,在其(qi)鋪(pu)設不小于80厘米(mi)(mi)的碎石(shi)墊(dian)層。如果當淤(yu)泥4-6米(mi)(mi)深,填(tian)土(tu)超過10米(mi)(mi),采(cai)用(yong)(yong)(yong)清淤(yu)拋石(shi)處(chu)理(li)方法(fa),一(yi)般(ban)(ban)(ban)清淤(yu)深度(du)為(wei)2-4米(mi)(mi),拋石(shi)厚度(du)一(yi)般(ban)(ban)(ban)為(wei)2-3m,讓(rang)其(qi)穩定后,采(cai)用(yong)(yong)(yong)壓實機械壓實,為(wei)保證(zheng)基(ji)礎整體性,建(jian)議還要在80厘米(mi)(mi)墊(dian)層中鋪(pu)設兩道(dao)土(tu)工格柵。當淤(yu)泥大于6米(mi)(mi)深時,采(cai)用(yong)(yong)(yong) CFG基(ji)樁加固,然(ran)后在其(qi)上填(tian)一(yi)層大于80cm厚的優質(zhi)砂礫墊(dian)層,并夯(hang)實緊密。
工(gong)程(cheng)開工(gong)前,對總(zong)體(ti)工(gong)程(cheng)進行質量策劃及質量計劃,對關鍵(jian)工(gong)序、重點(dian)及難點(dian)進行預控。做好技術交底工(gong)作,使操(cao)作人員明確(que)施工(gong)方法、操(cao)作要(yao)點(dian)和質量標(biao)準要(yao)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(bo)形鋼管涵原材料采購(gou)。在施(shi)工(gong)(gong)前(qian)對(dui)供方進行評價控(kong) 制,選擇合格有(you)信譽的供方。對(dui)施(shi)工(gong)(gong)使用的原材料, 按規定的頻(pin)率進行抽(chou)撿,不合格的材料堅決不用于(yu) 工(gong)(gong)程施(shi)工(gong)(gong)。嚴格控(kong)制施(shi)工(gong)(gong)質量。
