/> </p> <p style="text-align:center;"> <img src="https://tyunfile.71360.com/UploadFile/gzhezongda/637456992868698217/7319028.png" alt="" /> </p> <p style="text-align:center;"> <br /> </p> <p style="text-align:left;"> 施工中應(yīng)注意的問題 </p> <p> (1)在鉆進(jìn)過程中,由于鉆具受重力作用不斷下偏,致使鉆機(jī)上翹,鉆孔越長,此種現(xiàn)象越明顯,因此,鉆機(jī)就位的傾角應(yīng)比設(shè)計(jì)傾角少。 </p> <p> (2)偏心跟管鉆具在施工前應(yīng)逐一檢查沖擊器、偏心錘頭、導(dǎo)正器、套管靴和風(fēng)動(dòng)潛孔錘等,使之工作正常。偏心錘頭應(yīng)能靈活轉(zhuǎn)動(dòng),連接銷及鎖緊機(jī)構(gòu)應(yīng)牢固,鉆桿與潛孔錘和潛孔錘與偏心鉆具的連接應(yīng)可靠,套管和套管靴無裂紋。 </p> <p> (3)跟管鉆進(jìn)時(shí),在確認(rèn)鉆頭接觸到碎石土層后,先回轉(zhuǎn),待正常后,再開風(fēng)沖動(dòng)鉆進(jìn)。 </p> <p> (4)每鉆進(jìn)0.3M～0.5m應(yīng)強(qiáng)風(fēng)吹孔排粉一次,以保持孔內(nèi)清潔。吹孔時(shí),中心鉆具上提距離應(yīng)嚴(yán)加控制;禁止在鉆進(jìn)過程中向上起拔中心鉆具或來回倒桿。 </p> <p> (5)當(dāng)偏心頭回轉(zhuǎn)部分被巖渣卡住而不能收攏偏心頭時(shí),應(yīng)開動(dòng)空壓機(jī)重新對鉆孔進(jìn)行清洗,并使?jié)摽族N作短時(shí)間工作,然后再進(jìn)行試提,如此反復(fù),直至提出中心鉆具。 </p> <p> (6)跟管長度可根據(jù)地質(zhì)實(shí)際情況而定。當(dāng)不需跟管到位,跟管深度達(dá)到需要深度后可換用常規(guī)鉆頭進(jìn)行裸眼成孔。 </p> <p> (7)下索成功后,即可把套管拔出。在起拔套管時(shí),先將拔管機(jī)底座安裝在起拔基面上,再將油缸分左右或上下對稱安裝在底座上并固定,然后安上項(xiàng)盤及套管卡瓦,安好后啟動(dòng)油泵油缸充油,利用液壓傳力原理起拔套管。安裝油缸時(shí)油缸伸長方向要與套管軸線方向保持一致,以避免受力不同心而將套管折斷。 </p> <p> <br /> </p> <p
