產品詳細介紹
玻纖(xian)土工格柵的工程(cheng)應用:
1.瀝(li)青(qing)混(hun)(hun)凝(ning)土(tu)路(lu)(lu)面(mian)(mian)的(de)(de)(de)(de)高(gao)溫(wen)抗車(che)轍(che)(che)能(neng)(neng)力(li)(li)。在諸多因(yin)素的(de)(de)(de)(de)影(ying)響(xiang)下,容易(yi)造成(cheng)瀝(li)青(qing)混(hun)(hun)合料(liao)(liao)(liao)的(de)(de)(de)(de)高(gao)溫(wen)穩(wen)定性(xing)(xing)(xing)降(jiang)低,從而出現車(che)轍(che)(che)—這將影(ying)響(xiang)行車(che)的(de)(de)(de)(de)舒適性(xing)(xing)(xing),嚴重時甚至(zhi)存在交(jiao)通(tong)隱患。土(tu)工(gong)格(ge)柵(zha)(zha)在瀝(li)青(qing)混(hun)(hun)凝(ning)土(tu)路(lu)(lu)面(mian)(mian)中的(de)(de)(de)(de)應用,能(neng)(neng)夠瀝(li)青(qing)混(hun)(hun)凝(ning)土(tu)路(lu)(lu)面(mian)(mian)的(de)(de)(de)(de)支撐能(neng)(neng)力(li)(li),從而為交(jiao)通(tong)增加(jia)(jia)一層保障。此外,在瀝(li)青(qing)混(hun)(hun)合料(liao)(liao)(liao)中加(jia)(jia)人土(tu)工(gong)格(ge)柵(zha)(zha),可以加(jia)(jia)強(qiang)瀝(li)青(qing)混(hun)(hun)凝(ning)土(tu)路(lu)(lu)面(mian)(mian)的(de)(de)(de)(de)承載能(neng)(neng)力(li)(li),而且土(tu)工(gong)格(ge)柵(zha)(zha)作為獨(du)立的(de)(de)(de)(de)錨(mao)固(gu)點,對集料(liao)(liao)(liao)的(de)(de)(de)(de)位移加(jia)(jia)以限制(zhi),使(shi)得瀝(li)青(qing)混(hun)(hun)合料(liao)(liao)(liao)與格(ge)柵(zha)(zha)相互作用,對礦料(liao)(liao)(liao)骨架的(de)(de)(de)(de)穩(wen)定性(xing)(xing)(xing)具有重要意義。
2.延(yan)緩瀝(li)青混(hun)凝土(tu)路(lu)面出現裂縫。土(tu)工(gong)格(ge)(ge)柵中的(de)(de)塑料和網i的(de)(de)抗拉(la)強度(du)較大(da),將這(zhe)些混(hun)合料加人瀝(li)青混(hun)凝土(tu)結構層(ceng)中,能(neng)夠改善路(lu)面材(cai)料強度(du),并其的(de)(de)性能(neng)。當鋪設土(tu)工(gong)格(ge)(ge)柵后,能(neng)夠增(zeng)大(da)裂縫的(de)(de)擴展(zhan)角(jiao),起(qi)到延(yan)遲裂縫出現的(de)(de)作用。
3.降低瀝青(qing)(qing)層的(de)厚度(du)。當瀝青(qing)(qing)混凝(ning)土(tu)(tu)路(lu)面(mian)鋪設土(tu)(tu)工格(ge)柵(zha)(zha)后(hou),改變了(le)路(lu)面(mian)結構的(de)應(ying)(ying)力(li)分布(bu),能(neng)夠在(zai)土(tu)(tu)工格(ge)柵(zha)(zha)的(de)影(ying)響(xiang)下,降低瀝青(qing)(qing)混凝(ning)土(tu)(tu)混合料的(de)拉應(ying)(ying)力(li),從而加強(qiang)了(le)瀝青(qing)(qing)路(lu)面(mian)的(de)抗疲勞性能(neng),并延緩(huan)瀝青(qing)(qing)混凝(ning)土(tu)(tu)路(lu)面(mian)的(de)裂縫(feng)情況出現。在(zai)瀝青(qing)(qing)混凝(ning)土(tu)(tu)路(lu)面(mian)施工中采用土(tu)(tu)工格(ge)柵(zha)(zha),能(neng)夠降低瀝青(qing)(qing)厚度(du)可達5cm至10cm,對減少瀝青(qing)(qing)混合料的(de)用量具(ju)有重要(yao)作用。

玻纖土工(gong)格(ge)柵特(te)點(dian):
抗疲勞開裂
在(zai)(zai)舊(jiu)水泥(ni)混(hun)(hun)(hun)凝(ning)(ning)土(tu)(tu)路(lu)(lu)(lu)(lu)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)上(shang)的(de)(de)(de)瀝(li)青加(jia)(jia)(jia)鋪層(ceng),其主(zhu)要(yao)作(zuo)用(yong)是提(ti)高路(lu)(lu)(lu)(lu)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)的(de)(de)(de)使(shi)用(yong)功能,對承(cheng)(cheng)載(zai)(zai)作(zuo)用(yong)則(ze)貢獻不(bu)大,加(jia)(jia)(jia)鋪層(ceng)下(xia)的(de)(de)(de)剛性(xing)(xing)混(hun)(hun)(hun)凝(ning)(ning)土(tu)(tu)路(lu)(lu)(lu)(lu)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)仍(reng)起關(guan)鍵的(de)(de)(de)承(cheng)(cheng)載(zai)(zai)作(zuo)用(yong)。而(er)在(zai)(zai)舊(jiu)瀝(li)青混(hun)(hun)(hun)凝(ning)(ning)土(tu)(tu)路(lu)(lu)(lu)(lu)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)上(shang)進行(xing)瀝(li)青罩面(mian)(mian)(mian)(mian)(mian)(mian)(mian)則(ze)不(bu)同,瀝(li)青加(jia)(jia)(jia)鋪層(ceng)將(jiang)與舊(jiu)瀝(li)青混(hun)(hun)(hun)凝(ning)(ning)土(tu)(tu)路(lu)(lu)(lu)(lu)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)一起承(cheng)(cheng)載(zai)(zai)。因(yin)此(ci),在(zai)(zai)瀝(li)青混(hun)(hun)(hun)凝(ning)(ning)土(tu)(tu)路(lu)(lu)(lu)(lu)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)上(shang)進行(xing)瀝(li)青罩面(mian)(mian)(mian)(mian)(mian)(mian)(mian),除了會出現反射裂(lie)縫,同時還會因(yin)為荷(he)載(zai)(zai)的(de)(de)(de)長(chang)(chang)期作(zuo)用(yong)而(er)出現疲勞開裂(lie)。我們對舊(jiu)瀝(li)青混(hun)(hun)(hun)凝(ning)(ning)土(tu)(tu)路(lu)(lu)(lu)(lu)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)上(shang)的(de)(de)(de)瀝(li)青加(jia)(jia)(jia)鋪層(ceng)受(shou)荷(he)情(qing)況(kuang)做(zuo)受(shou)力(li)(li)(li)分析:由于瀝(li)青罩面(mian)(mian)(mian)(mian)(mian)(mian)(mian)層(ceng)下(xia)為與瀝(li)青罩面(mian)(mian)(mian)(mian)(mian)(mian)(mian)層(ceng)同一性(xing)(xing)質的(de)(de)(de)柔(rou)性(xing)(xing)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)層(ceng),當受(shou)到(dao)(dao)荷(he)載(zai)(zai)作(zuo)用(yong)時,路(lu)(lu)(lu)(lu)表將(jiang)發生彎沉(chen)。在(zai)(zai)直接(jie)與車輪接(jie)觸(chu)的(de)(de)(de)瀝(li)青罩面(mian)(mian)(mian)(mian)(mian)(mian)(mian)層(ceng)受(shou)到(dao)(dao)壓力(li)(li)(li),在(zai)(zai)輪載(zai)(zai)邊緣以外的(de)(de)(de)區域(yu),面(mian)(mian)(mian)(mian)(mian)(mian)(mian)層(ceng)受(shou)到(dao)(dao)拉力(li)(li)(li)作(zuo)用(yong),由于兩處(chu)受(shou)力(li)(li)(li)區域(yu)所受(shou)力(li)(li)(li)性(xing)(xing)質不(bu)同,而(er)又彼此(ci)緊靠,因(yin)此(ci)在(zai)(zai)兩塊受(shou)力(li)(li)(li)區域(yu)的(de)(de)(de)交界處(chu)即力(li)(li)(li)的(de)(de)(de)突變處(chu)容易(yi)發生破壞(huai)。在(zai)(zai)長(chang)(chang)期荷(he)載(zai)(zai)的(de)(de)(de)作(zuo)用(yong)下(xia),發生疲勞開裂(lie)。
玻纖(xian)格柵(zha)(zha)在(zai)瀝青罩(zhao)面層(ceng)中,能夠將上(shang)述(shu)的壓應(ying)(ying)力(li)(li)與拉應(ying)(ying)力(li)(li)分散,在(zai)兩塊受力(li)(li)區域之(zhi)間形成緩沖帶,在(zai)這里應(ying)(ying)力(li)(li)逐步(bu)變(bian)(bian)化(hua)而不(bu)是突(tu)變(bian)(bian),減少了(le)應(ying)(ying)力(li)(li)突(tu)變(bian)(bian)對瀝青罩(zhao)面層(ceng)的破壞。同(tong)時玻纖(xian)格柵(zha)(zha)的低延伸率(lv)減小了(le)路面的彎沉量,保(bao)證了(le)路面不(bu)會發生過渡變(bian)(bian)形。
