公路翻浆病害铺设土工布效果明显
无纺(fang)土工(gong)(gong)(gong)布(bu)的特(te)点。用以道(dao)路工(gong)(gong)(gong)程的无纺(fang)土工(gong)(gong)(gong)布(bu)是这(zhei)种(zhong)聚脂涤纶无纺(fang)土工(gong)(gong)(gong)纤维材料，关键有(you)(you)下列特(te)性(xing):①耐热。沥青混凝土路面施(shi)工(gong)(gong)(gong)时溫(wen)度达(da)到(dao)150℃上下，故规定隔层原材料再此溫(wen)度下不可(ke)以收拢或熔融、打卷形(xing)变(bian)。该土工(gong)(gong)(gong)布(bu)以聚脂为原材料，溶点达(da)到(dao)230℃，在路面施(shi)工(gong)(gong)(gong)时特(te)性(xing)平稳，不容易(yi)产(chan)生(sheng)一切(qie)转(zhuan)变(bian)、②经伟向均具备较高的抗(kang)抗(kang)压强度、③吸附力好、其表层匀称，亲水性(xing)好、④具备优良的有(you)(you)机(ji)化学平稳和抗(kang)微生(sheng)物特(te)性(xing)。
无纺土工布的(de)(de)功效。①运(yun)用土工布纺织物的(de)(de)撕(si)破抗压强度和(he)必(bi)须的(de)(de)延展性，使农村基(ji)层混凝土裂(lie)缝(feng)造成(cheng)的(de)(de)地应力拓展至更宽范(fan)畴(chou)，减轻裂(lie)缝(feng)处的(de)(de)应力，具有消化(hua)吸收一部分拉申动能(neng)的(de)(de)功效。②土工织物浸(jin)湿沥(li)青(qing)后产(chan)生(sheng)密封(feng)性地面防水，避免地下水渗透到(dao)农村基(ji)层，使农村基(ji)层原材(cai)料不至深化(hua)恶变。
无(wu)纺土工布(bu)设(she)置方法(fa)。①针对翻浆病(bing)(bing)虫害(hai)建在(zai)农(nong)(nong)村(cun)(cun)基(ji)层(ceng)(ceng)(ceng)墙顶(ding)(ding)，若农(nong)(nong)村(cun)(cun)基(ji)层(ceng)(ceng)(ceng)出現病(bing)(bing)虫害(hai)，挖除农(nong)(nong)村(cun)(cun)基(ji)层(ceng)(ceng)(ceng)后(hou)在(zai)其(qi)底边铺装(zhuang)无(wu)纺土工布(bu),②针对开裂和孔(kong)洞病(bing)(bing)虫害(hai)在(zai)农(nong)(nong)村(cun)(cun)基(ji)层(ceng)(ceng)(ceng)墙顶(ding)(ding)设(she)定。③铺装(zhuang)土工布(bu)前均在(zai)农(nong)(nong)村(cun)(cun)基(ji)层(ceng)(ceng)(ceng)墙顶(ding)(ding)喷撒透层(ceng)(ceng)(ceng)油。
