class="page-proshow02"><p class="title">詳細(xì)說(shuō)明</p><div id="v33pgx7" class="box"><p><p> 經(jīng)常從事固體礦產(chǎn)地質(zhì)勘探行業(yè)的人應(yīng)該是十分了解巖心鉆探的。而跟管鉆進(jìn)作為地質(zhì)巖心鉆探的一種特殊方法，相關(guān)工作者應(yīng)該也不會(huì)對(duì)它感到陌生。 </p> <p> 什么是跟管呢？跟管就是由國(guó)金金屬制作而成的一種金屬管，它就是用來(lái)做跟管鉆進(jìn)施工的。跟管鉆進(jìn)技術(shù)雖然能輕松解決勘測(cè)或施工時(shí)遇到的難題，但它對(duì)跟管的要求非常高，而且所采用的設(shè)備需要配置多種鉆具。并且鉆具的配置要盡量好一些，因?yàn)殂@孔效率很大程度上受它的影響。 </p> <p style="text-align:center;"> <img src="https://tyunfile.71360.com/UploadFile/gzhezongda/637466620544212042/2081991.jpg" alt="" /> </p> <p> 在進(jìn)行跟管鉆進(jìn)時(shí)，要一邊進(jìn)行鉆進(jìn)一邊壓入套管，或者將套管超前壓入，然后鉆具再跟著鉆進(jìn)。這種鉆進(jìn)方法能夠避免在在鉆進(jìn)過(guò)程中的孔壁坍塌和流砂等充塞鉆孔，因此這種方法適用于松散地層和流砂層的鉆進(jìn)。在大直徑工程鉆進(jìn)中，由于下套管需要大的扭矩和功率，因此經(jīng)常配備被稱為搓管機(jī)的機(jī)械來(lái)進(jìn)行邊鉆進(jìn)邊下套管的作業(yè)。除此此外，它也是對(duì)付覆蓋層鉆進(jìn)的有效方法之一。 </p> <p> 跟管鉆進(jìn)分為偏心跟管鉆進(jìn)以及同心跟管鉆進(jìn)兩種方式。偏心跟管鉆進(jìn)適用于孔深在40米以內(nèi)并且無(wú)較多較大的石頭的地層。而同心式跟管鉆進(jìn)則與之相反，在孔深超過(guò)40米切地層中有較多較大的石頭是采用。 </p> <p> 當(dāng)施工時(shí)遇上破碎層松軟的地質(zhì)，或者是很難成孔的地層，在這種情況下，普通的鉆進(jìn)方式很難進(jìn)行施工，此時(shí)就可以采用跟管鉆進(jìn)，不但解決了難題，也提高了工作效率。 </p> <p>
