1、填料要求
一般情況(kuang)下,采用石灰土、砂礫土以(yi)及素填(tian)(tian)土等作為(wei)填(tian)(tian)料(liao)(liao),填(tian)(tian)料(liao)(liao)的(de)含水量(liang)達到最佳狀(zhuang)態時(shi)才能進(jin)(jin)行(xing)(xing)填(tian)(tian)筑。在(zai)對填(tian)(tian)料(liao)(liao)進(jin)(jin)行(xing)(xing)填(tian)(tian)筑時(shi),首(shou)先要(yao)進(jin)(jin)行(xing)(xing)基底處理(li),其次,在(zai)填(tian)(tian)筑填(tian)(tian)料(liao)(liao)前,應當對填(tian)(tian)料(liao)(liao)的(de)含水量(liang)進(jin)(jin)行(xing)(xing)試驗,按照試驗結果來確定最佳的(de)含水量(liang)。
2、土工格柵鋪設
土工(gong)(gong)(gong)格(ge)柵鋪設時將其(qi)搭(da)接長(chang)度(du)(du)控制在(zai)30cm左右,并且(qie)要(yao)保證每層之間的搭(da)接長(chang)度(du)(du)不能(neng)小(xiao)于10cm。一般情況下,每層鋪設土工(gong)(gong)(gong)格(ge)柵之前(qian)都需(xu)要(yao)將其(qi)鋪至設計標高。并且(qie)為(wei)了保證路(lu)基工(gong)(gong)(gong)程施(shi)(shi)工(gong)(gong)(gong)質量(liang)得到有效(xiao)提升,施(shi)(shi)工(gong)(gong)(gong)人員還需(xu)要(yao)將其(qi)搭(da)接部(bu)分設置為(wei)斜坡狀(zhuang),以便于機械(xie)施(shi)(shi)工(gong)(gong)(gong)。
3、土工格柵安裝
在安裝土工(gong)格(ge)柵前,應當將其表(biao)面(mian)清理(li)干凈并確保其表(biao)面(mian)干燥,在對土工(gong)格(ge)柵進行安裝時(shi),必須(xu)保證土工(gong)格(ge)柵具有足夠的(de)強度和剛度。因此,施工(gong)人員(yuan)需(xu)要對土工(gong)格(ge)柵縱向搭(da)接部分進行加(jia)密處理(li),同時(shi)還需(xu)要控制搭(da)接長度。
4、土工格柵路堤填(tian)筑
在對土工(gong)格柵路堤的填(tian)(tian)筑(zhu)中,應當采用(yong)分層填(tian)(tian)筑(zhu)法(fa)對填(tian)(tian)料(liao)進行填(tian)(tian)筑(zhu),并(bing)且為了保(bao)證填(tian)(tian)筑(zhu)的質量和效率,施工(gong)人員還需要保(bao)證填(tian)(tian)料(liao)的含水量處于最佳狀態。填(tian)(tian)筑(zhu)時應做(zuo)好厚度(du)控(kong)制,保(bao)證每層之間(jian)的厚度(du)小(xiao)于30cm。
5、路基排水
在(zai)設(she)(she)計路基(ji)排水(shui)系(xi)(xi)統時,施工(gong)(gong)人(ren)員還需要(yao)在(zai)路基(ji)底(di)部設(she)(she)置相應的排水(shui)系(xi)(xi)統。通常(chang)情況(kuang)下,施工(gong)(gong)人(ren)員可利用滲溝(gou)或者截水(shui)溝(gou)來進行(xing)路基(ji)排水(shui)系(xi)(xi)統的設(she)(she)計和建設(she)(she)。此外,在(zai)路基(ji)施工(gong)(gong)完成后應及時做好檢查和驗收工(gong)(gong)作,保(bao)證路基(ji)工(gong)(gong)程(cheng)項(xiang)目在(zai)投(tou)入使用后能夠有效地延長其使用壽命。
