   近些年来(lai)(lai),土(tu)工(gong)(gong)(gong)格(ge)栅(zha)(zha)在公路、铁(tie)路路基(ji)(ji)方面的应用(yong)越(yue)(yue)来(lai)(lai)越(yue)(yue)多,格(ge)栅(zha)(zha)用(yong)作(zuo)加(jia)(jia)固地基(ji)(ji),提高承(cheng)载力,减小垫层(ceng)厚(hou)度(du)(du)等(deng)(deng)方面的作(zuo)用(yong)很(hen)明显。很(hen)多室内试验也探(tan)讨了加(jia)(jia)筋(jin)(jin)层(ceng)数(shu)、垫层(ceng)厚(hou)度(du)(du)、地基(ji)(ji)土(tu)强(qiang)度(du)(du)等(deng)(deng)因(yin)素(su)对加(jia)(jia)筋(jin)(jin)效(xiao)果(guo)的影(ying)响。在我国各种现行的设计规范中,对地基(ji)(ji)加(jia)(jia)固用(yong)土(tu)工(gong)(gong)(gong)格(ge)栅(zha)(zha)的选取(qu),还是以抗拉(la)(la)强(qiang)度(du)(du)作(zuo)为唯(wei)一(yi)指标,而未考(kao)虑不(bu)(bu)同生产工(gong)(gong)(gong)艺、不(bu)(bu)同原材(cai)料(liao)、不(bu)(bu)同物理、力学性质的土(tu)工(gong)(gong)(gong)格(ge)栅(zha)(zha)的不(bu)(bu)同加(jia)(jia)筋(jin)(jin)效(xiao)果(guo),结(jie)果(guo)造(zao)成(cheng)地基(ji)(ji)加(jia)(jia)固用(yong)的土(tu)工(gong)(gong)(gong)格(ge)栅(zha)(zha)的抗拉(la)(la)强(qiang)度(du)(du)越(yue)(yue)来(lai)(lai)越(yue)(yue)高。实际上,国外早(zao)已开始(shi)研(yan)究(jiu)影(ying)响加(jia)(jia)筋(jin)(jin)效(xiao)果(guo)的因(yin)素(su),美(mei)国工(gong)(gong)(gong)程兵(bing)团⑴⑵在二(er)十世纪(ji)九十年代对轻型飞机下柔性路面基(ji)(ji)层(ceng)中的格(ge)栅(zha)(zha)做了大量研(yan)究(jiu),得出影(ying)响加(jia)(jia)筋(jin)(jin)效(xiao)果(guo)的一(yi)些主(zhu)要因(yin)素(su),格(ge)栅(zha)(zha)的强(qiang)度(du)(du)没有位(wei)列其中。*
   土(tu)工格(ge)栅市(shi)场(chang)的蓬勃(bo)发(fa)展出(chu)乎J9九游会AG 很多人的意料,这种90年代(dai)从国(guo)外引进(jin)的新型建筑材料,今(jin)天被(bei)广(guang)泛使用在各种路基路面以(yi)及高(gao)强度(du)要求的土(tu)木工程中。随着市(shi)场(chang)需求的不断扩(kuo)大,生产企(qi)业也如雨(yu)后春(chun)笋般出(chu)现(xian)(xian),竞争的激烈导致各种质量水平和价格(ge)的出(chu)现(xian)(xian),作(zuo)为采购者应(ying)该如何选择?
    本公司坚持(chi)用(yong)(yong)质(zhi)量去开创市(shi)场,不与同行搞(gao)价格(ge)战,因为价格(ge)战最终的结局是连败俱(ju)伤,而且(qie)客户最终也成为受害(hai)者。价格(ge)战必然会(hui)影响(xiang)产(chan)品(pin)质(zhi)量,为了减少成本,会(hui)用(yong)(yong)降(jiang)低原材料标准的方(fang)式节(jie)约材料成本,直接导致产(chan)品(pin)外观(guan)、强度各方(fang)面的下降(jiang).*
土(tu)工(gong)(gong)格(ge)(ge)栅(zha)的(de)价格(ge)(ge),根据不(bu)同材质(zhi)与强(qiang)度(du)大(da)小进行区(qu)分,强(qiang)度(du)越(yue)高价格(ge)(ge)越(yue)贵,没有经过出厂强(qiang)力(li)实(shi)验的(de)产品,负责人的(de)厂家是不(bu)会出厂或者进行型号降(jiang)低后出厂。土(tu)工(gong)(gong)格(ge)(ge)栅(zha)的(de)质(zhi)量决定着工(gong)(gong)程(cheng)质(zhi)量,土(tu)工(gong)(gong)格(ge)(ge)栅(zha)质(zhi)量只是一个方面,像施工(gong)(gong)中使用填料的(de)质(zhi)量也会影响土(tu)工(gong)(gong)格(ge)(ge)栅(zha)作用的(de)发(fa)挥。
    土(tu)(tu)工格(ge)(ge)栅(zha)按产(chan)品的受力形式(shi)分为双向土(tu)(tu)工格(ge)(ge)栅(zha)和单向土(tu)(tu)工格(ge)(ge)栅(zha)、按产(chan)品的物质构(gou)成分为玻璃纤维土(tu)(tu)工格(ge)(ge)栅(zha),合(he)成纤维土(tu)(tu)工格(ge)(ge)栅(zha),聚丙乙烯土(tu)(tu)工格(ge)(ge)栅(zha)、钢塑复(fu)合(he)土(tu)(tu)工格(ge)(ge)栅(zha)。
聚(ju)乙烯(xi)单(dan)向(xiang)土工(gong)格栅(zha)近几年聚(ju)丙乙烯(xi)单(dan)向(xiang)土工(gong)格栅(zha)在旧路路基施工(gong)中应用较为普遍,它能够有(you)效防治路基的不均(jun)匀沉(chen)降、纵(zong)向(xiang)裂(lie)(lie)缝和旧路面的裂(lie)(lie)缝的反射。
    PE/PP土工格栅(zha)是由高(gao)分子聚合物(wu)经(jing)挤(ji)出、双向拉伸(shen)而成,拉伸(shen)强(qiang)度大(da),适用(yong)于(yu)(yu)各(ge)种土壤(rang),其(qi)各(ge)项性能(neng)指标都优于(yu)(yu)未经(jing)拉伸(shen)的(de)(de)土工网,是目前最(zui)理(li)想的(de)(de)加(jia)(jia)筋(jin)(jin)加(jia)(jia)固材料之(zhi)一(yi)(yi)。该(gai)格栅(zha)可广泛应(ying)用(yong)于(yu)(yu)高(gao)速公(gong)路(lu)、市政道(dao)路(lu)、铁(tie)路(lu)、飞机(ji)跑道(dao)等路(lu)基(ji)增强(qiang),公(gong)路(lu)、铁(tie)路(lu)以及江河海(hai)岸边的(de)(de)加(jia)(jia)筋(jin)(jin)土挡墙的(de)(de)加(jia)(jia)筋(jin)(jin)工程(cheng);江河海(hai)坝的(de)(de)堤坝增强(qiang);矿井加(jia)(jia)固以及果(guo)园、菜地(di)、牲畜、工地(di)围栏(lan)等众多领(ling)域(yu),随(sui)着通佳机(ji)械与全(quan)球第(di)一(yi)(yi)煤炭生(sheng)产(chan)企(qi)业神华集团的(de)(de)成功合作,此(ci)种产(chan)品在矿井加(jia)(jia)固领(ling)域(yu)的(de)(de)应(ying)用(yong)得到了大(da)力的(de)(de)推广。*
土(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)格(ge)(ge)(ge)栅(zha)(zha)(zha)应用(yong)越(yue)来越(yue)广泛。土(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)格(ge)(ge)(ge)栅(zha)(zha)(zha)由(you)(you)20世纪(ji)80年代引入中国,几年前在工(gong)(gong)(gong)(gong)(gong)程(cheng)基地(di)上(shang)找(zhao)个人(ren)问:"知(zhi)道(dao)什么是土(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)格(ge)(ge)(ge)栅(zha)(zha)(zha)吗?"?"很多人(ren)都摇头。随着土(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)格(ge)(ge)(ge)栅(zha)(zha)(zha)生产规模(mo)的(de)(de)(de)(de)壮大(da),土(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)格(ge)(ge)(ge)栅(zha)(zha)(zha)生产技术的(de)(de)(de)(de)提高(gao)创(chuang)新(xin),土(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)格(ge)(ge)(ge)栅(zha)(zha)(zha)被(bei)大(da)量(liang)的(de)(de)(de)(de)应用(yong)的(de)(de)(de)(de)公路、铁路的(de)(de)(de)(de)修建(jian)当中,一些(xie)湿地(di)、沼泽以及港(gang)口(kou)等(deng)土(tu)(tu)(tu)木(mu)工(gong)(gong)(gong)(gong)(gong)程(cheng)的(de)(de)(de)(de)处理更(geng)加热衷(zhong)于使用(yong)土(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)格(ge)(ge)(ge)栅(zha)(zha)(zha)。由(you)(you)于土(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)格(ge)(ge)(ge)栅(zha)(zha)(zha)的(de)(de)(de)(de)作(zuo)用(yong)和特性,可以大(da)大(da)的(de)(de)(de)(de)减少土(tu)(tu)(tu)木(mu)工(gong)(gong)(gong)(gong)(gong)程(cheng)的(de)(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)作(zuo)量(liang),提高(gao)土(tu)(tu)(tu)木(mu)工(gong)(gong)(gong)(gong)(gong)程(cheng)的(de)(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)作(zuo)效率和质(zhi)量(liang),土(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)格(ge)(ge)(ge)栅(zha)(zha)(zha)系(xi)列(lie)产品越(yue)来越(yue)受欢迎。*
