土工织物：水利、铁路、建筑，无所不能

土工(gong)织(zhi)(zhi)(zhi)物(wu)(wu)按(an)照织(zhi)(zhi)(zhi)造(zao)方(fang)法不同，分为有纺土工(gong)织(zhi)(zhi)(zhi)物(wu)(wu)和(he)非织(zhi)(zhi)(zhi)造(zao)土工(gong)织(zhi)(zhi)(zhi)物(wu)(wu)。有纺土工(gong)织(zhi)(zhi)(zhi)物(wu)(wu)是(shi)由长丝(扁丝)按(an)一定(ding)方(fang)向(xiang)排(pai)列机织(zhi)(zhi)(zhi)(编(bian)织(zhi)(zhi)(zhi))而成(cheng)；而非织(zhi)(zhi)(zhi)造(zao)土工(gong)织(zhi)(zhi)(zhi)物(wu)(wu)是(shi)由短(duan)纤维或(huo)长丝按(an)随机或(huo)定(ding)向(xiang)排(pai)列，制(zhi)成(cheng)薄网(纤网)，再(zai)经机械(xie)(针(zhen)刺、水刺)固结、热黏(nian)合或(huo)化学黏(nian)合制(zhi)备(bei)而成(cheng)。

土工(gong)织(zhi)物(wu)由于其在隔离、排水(shui)、加筋(jin)、反滤(lv)性(xing)(xing)(xing)(xing)能上的(de)(de)优秀表(biao)现，被广泛应用(yong)于水(shui)利、水(shui)电(dian)、铁路、公路、海(hai)港(gang)、建筑、采矿、军工(gong)等领域。土工(gong)织(zhi)物(wu)在生(sheng)产、施(shi)工(gong)过程中(zhong)需要对(dui)其力(li)学、水(shui)力(li)学、耐久性(xing)(xing)(xing)(xing)等性(xing)(xing)(xing)(xing)能进行(xing)质量检测，其性(xing)(xing)(xing)(xing)能的(de)(de)好坏直(zhi)接影响工(gong)程建设的(de)(de)质量，而检测的(de)(de)首(shou)要步(bu)骤是将土工(gong)织(zhi)物(wu)制(zhi)成相应规格的(de)(de)试(shi)样，再进行(xing)相应的(de)(de)试(shi)验。随着土工(gong)织(zhi)物(wu)检测体系的(de)(de)逐(zhu)步(bu)完(wan)善，测试(shi)结果(guo)的(de)(de)准(zhun)确性(xing)(xing)(xing)(xing)也逐(zhu)步(bu)提高，试(shi)样裁剪尺寸精(jing)度成为决定检测准(zhun)确性(xing)(xing)(xing)(xing)的(de)(de)重(zhong)要因素之一。

目前(qian)国内检测机构主要采(cai)用(yong)先在样(yang)(yang)品上(shang)绘制(zhi)(zhi)(zhi)试(shi)样(yang)(yang)轮廓(kuo)，然后人工(gong)裁剪试(shi)样(yang)(yang)的(de)方法，整个过程耗时耗力，不(bu)仅效率低下，而且(qie)制(zhi)(zhi)(zhi)出的(de)样(yang)(yang)品精度(du)差(cha)，直接导致检测结果偏离真实值(zhi)。本文将介绍自主研发的(de)土(tu)(tu)工(gong)织物自动(dong)化制(zhi)(zhi)(zhi)样(yang)(yang)设备(bei)，主要用(yong)于(yu)高(gao)效制(zhi)(zhi)(zhi)作各种土(tu)(tu)工(gong)织物试(shi)验用(yong)样(yang)(yang)品，大(da)幅提(ti)高(gao)制(zhi)(zhi)(zhi)样(yang)(yang)的(de)效率和准确性。
