4、。做好排水系統(tǒng)應(yīng)保證排水通道暢通以利軟土排水固結(jié)。b.將質(zhì)量合格的砂運至施工現(xiàn)場,按計算用量卸料,用人工配合推土機按設(shè)計厚度鋪設(shè)砂墊層并壓實。c.繪制方格網(wǎng)圖并現(xiàn)場院放樣,用方格網(wǎng)控制,標(biāo)示插板位置,使板距誤差控制在允許范圍內(nèi)。d.選擇插板機(有輪胎式,鏈條式,軌道式),機上應(yīng)刻用明顯的井尺標(biāo)志。如選用軌道式插板機時,要事先鋪設(shè)與路基中線垂直的軌道。e.就位插板機,調(diào)好機架的平整度和套管的垂直度,使排水板的垂直度偏差控制在允許范圍內(nèi)。f.將排水板插入套管,起動振動錘,將套管和排水板壓入土中。g.排水板進尺長度要定夠,不允許使用搭接延續(xù)的排水板。
5、排水板的入土深度不得小于設(shè)計深度。h.輸送滾軸反轉(zhuǎn),松開排水板,套管上提,排隊水板留在土中滿足設(shè)計深度,套管上提時,跟帶排水板的長度不大于50cm。i.在地面以上20cm處切斷排水板,移向下一孔位施工。SelectionParagraphFormatLineSpacingLinesToPointsSelectionParagraphFormatLineSpacingLinesToPointselectionParagraaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaphFormatLineSpac
