如何加强渠道防渗工程的质量管理以HDPE土工膜为例

在(zai)现代社(she)会(hui)中，我国水(shui)利工(gong)(gong)(gong)程(cheng)(cheng)的(de)数量逐渐增加。在(zai)这种(zhong)新形势下(xia)，渠道防(fang)(fang)渗工(gong)(gong)(gong)程(cheng)(cheng)在(zai)我国南水(shui)北调(diao)(diao)中线工(gong)(gong)(gong)程(cheng)(cheng)实际(ji)建(jian)设(she)中占有非(fei)常重要(yao)的(de)地位。在(zai)此基础上，在(zai)渠道防(fang)(fang)渗工(gong)(gong)(gong)程(cheng)(cheng)正常施工(gong)(gong)(gong)时，需要(yao)加强(qiang)质(zhi)量管(guan)理，有效提高其整体质(zhi)量和实际(ji)效果(guo)(guo)。通过这种(zhong)方(fang)法，为(wei)相关企(qi)业创造更(geng)多的(de)社(she)会(hui)价值(zhi)和经济效益，节约成本(ben)和支(zhi)出，确保工(gong)(gong)(gong)程(cheng)(cheng)项目的(de)整体施工(gong)(gong)(gong)效果(guo)(guo)。因(yin)此，加强(qiang)南水(shui)北调(diao)(diao)中线工(gong)(gong)(gong)程(cheng)(cheng)渠道防(fang)(fang)渗工(gong)(gong)(gong)程(cheng)(cheng)质(zhi)量管(guan)理研(yan)究具有现实意义。

HDPE土工(gong)膜(mo)主要用于垃圾填埋(mai)场、景观湖泊和池(chi)塘(tang)；铺(pu)设(she)基(ji)层(ceng)平坦。一般来说，膜(mo)上(shang)设(she)计有保(bao)护层(ceng)，泄漏风险(xian)不高(gao)(gao)。然(ran)而(er)，钢筋混凝土池(chi)壁的铺(pu)设(she)仍然(ran)是(shi)第一次施工(gong)。施工(gong)过(guo)程(cheng)中(zhong)存(cun)在两个主要问题：一是(shi)在7m高(gao)(gao)池(chi)壁上(shang)铺(pu)设(she)防渗(shen)膜(mo)。防渗(shen)膜(mo)直(zhi)接(jie)承受(shou)重力(li)(li)和污(wu)水冲击，需要消除局部应力(li)(li)、应力(li)(li)变形等(deng)缺陷；二是(shi)本工(gong)程(cheng)的防渗(shen)等(deng)级(ji)要求为一级(ji)，设(she)计用途为全(quan)厂污(wu)水和高(gao)(gao)盐水处理(li)。隐蔽后，一旦有漏点(dian)，就会(hui)漏水，造成水污(wu)染，社会(hui)影(ying)响大，维护成本高(gao)(gao)。因此(ci)，防渗(shen)膜(mo)铺(pu)设(she)时的质(zhi)量控(kong)制应列为重点(dian)工(gong)作(zuo)。
