(1)舊聲測(cè)管在打設(shè)前需進(jìn)行整修矯正。矯正要在平臺(tái)上進(jìn)行，對(duì)彎曲變形的聲測(cè)管可用油壓千斤頂頂壓或火烘等方法矯正。 </p> <p> (2)作好圍擦支架，以保證聲測(cè)管垂直打入和打入后的聲測(cè)管墻面平直。 </p> <p> (3)防止聲測(cè)管鎖口中心線位移，可在打樁進(jìn)行方向的聲測(cè)管鎖口處設(shè)卡板，阻止板樁位移。 </p> <p> (4)為保證聲測(cè)管垂直用2臺(tái)經(jīng)緯儀從兩個(gè)方向控制錘擊人土。 </p> <p> (5)由于聲測(cè)管打入時(shí)傾斜，且鎖口接合部有空隙，封閉合攏比較困難。解決的辦法一是用異形板樁(此法較困難);二是采用軸線封閉法，此法較為方便。 </p><p> 聲測(cè)管的運(yùn)輸方式一般都是采用汽運(yùn)方式，考慮多種因素的問題選擇汽運(yùn)配貨(配貨)和整車汽運(yùn)(包車)兩種方式。下面聲測(cè)管廠家就來說說運(yùn)輸方式的選擇。 </p> <p> 整車運(yùn)輸聲測(cè)管的情況： </p> <p> 1、工地特別偏或是離工廠特別近，沒法進(jìn)行配貨，這種情況下不得不包車。 </p> <p> 2、體積達(dá)到或接近車輛能夠容納的體積(一般為鉗壓式聲測(cè)管)，這樣車輛同樣不能夠配其他貨物，繼承配貨造成運(yùn)輸本錢更高或是超載。 </p> <p> 3、噸位達(dá)到或接近車輛載重量(一般是螺旋式聲測(cè)管)。假如再裝別得貨就超載，這種情況下只能包車采用整車運(yùn)輸。或者是只能夠配特別少的貨，這種情況下司機(jī)多地卸貨本錢太高，也必需包車。 </p> <p> 4、工地特別著急使用，要求運(yùn)輸時(shí)間短，必需包車才能夠按要求運(yùn)抵工地。 </p> <p> 反之，則采用配貨運(yùn)輸聲測(cè)管。主要知足以下前提，配貨比較利便，聲測(cè)管裝完之后車輛的噸位和體積遠(yuǎn)低于載重，工地施工聲測(cè)管不是很著急。液壓聲測(cè)管哪個(gè)廠家好，云南貿(mào)軒商貿(mào)有限公司。</p><div style="width:100%;text-align: center;"><img style="max-width:
