normal drilling 中文意思是什麼
normal drilling
解釋
正常鉆井-
This drilling adopts crank connecting link and walking beam percussion mechanism, which make the drilling possess two percussive functions, normal drilling takes connecting link impact as main mode, when encountering special situation and the connecting link impact can not drill, it can transform into hoisting impact, the stroke length can be modulated, it realizes automatic percussive drilling due to continuous operating of connecting link percussive mechanism, these can enhance drilling efficiency and relieve labor intensity ; it adopts pumping reverse circulation to drain slag, which not only resolves the drilling difficulty in special stratum such as pebble and gravel stratum and hard stratum, but also resolves the problem that the percussive drill ' s efficiency is low ; it adopts spur gear differential mechanism as double cylinders lazy tongs of main hoist, which not only ensures the balance state of drilling tool, but also reduces the mechanical design, and reduces the cost ; the bottom plate traveling motion of this drilling machine adopts walking type ; the drilling tower adopts hydraulic pressure uprising, and reduces the assistant operating time
該鉆機採用曲柄連桿、游梁式沖擊機構，使鉆機具有兩種沖擊功能;正常鉆進以連桿沖擊為主，遇到特殊情況，用連桿沖擊不能鉆進時，可轉為卷揚沖擊，沖程可調，因連桿沖擊機構連續工作，所以實現了自動沖擊鉆進，可提高鉆進效率，減輕勞動強度;採用泵吸反循環的方式排渣，既能有效解決卵礫石地層、堅硬地層等特殊地層鉆進的困難，又很好地解決了沖擊鉆機效率低下的問題;採用直齒圓柱齒輪差速機構作為主卷揚的雙筒同步機構，既保證了鉆具處于平衡狀態，又大大簡化了該機構設計，降低了成本;該鉆機底盤行走移位採用步履式;鉆塔採用液壓起立，減少了輔助作業時間。 -
Model lb fishing cup is a practical and effective tool. during drilling operation, it can be used to recover the heavier drilling cuttings or metal chips which are difficult to be lifted out of the borehole by normal drillig fluid circulation
它是用來撈取鉆井過程中正常的泥漿循環無法帶出井眼的較重鉆屑或金屬碎屑的一種實用有效的隨鉆工具。 -
In order to ensure the safety of engineering, it should be careful to use the test result of normal drilling sampling, the pitting sampling, shaft sampling, or double - tubles and thin - wall soil collecting methods should be used
為保證工程安全，對常規鉆孔取樣試驗成果的使用應當慎重，對重要工程宜採用探坑、豎井取樣，或採用雙筒薄壁取土技術。 -
According to the actual conditions that normal standard of selecting guiding drilling ' s rig at present lack and still depend on experience in many situations, adopt the modern artificial intelligence technology - case - based reasoning to solve this problem
根據目前導向鉆進施工設備選擇缺乏成熟的、規范的標準，在許多情況下仍然依靠經驗的實際情況，採用現代的人工智慧技術? ?基於範例推理的方法來解決這一問題。
