鉆渣 的英文怎麼說
中文拼音 [zhēnzhā]
鉆渣
英文
boring mud-
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。This paper described the basic principle and construction type of the linear accelerometers, and calculated system response to various forces. it deduced essential parameters which affect measurement accuracy of accelerometers, and it also explained the measurement and selection methods of parameters about accelerometers
通過敘述鑿巖排渣不順利所引起的後果，分析了影響排渣的各種因素，說明了在不同鉆鑿巖孔的條件下的排渣能力，對鑿巖機械的使用者和設計製造者來說，很有參考價值In recent years we have been getting the feeling that bourgeois ideology and the dregs of society invariably try to worm their way to the surface
我們這幾年假如說有經驗，有這樣一條，就是資產階級思想的影響，社會渣滓的影響，總要鉆出來。Simulative experiment of pneumatic slagoff for boreholes in coal seams
煤層鉆孔風力排渣模擬實驗研究Impact of bottom settlings and mud cake on vertical supporting capacity of large - diameter predrilled cast - in - place pile
樁底沉渣與樁周泥皮對大直徑鉆孔灌注樁豎向承載力的影響分析The drilling hole pour pile technique has been wide - ranging used in the high buildings " foundation and base of the wide span construction and base of bearing weighty load construction, but the geology conditions that surrounding the pile are differ in thousands of ways, extraordinary, the soil there is small opening and it can be compressed and the bottom of the pile ' s hole there is much more dregs, so many confuse reasons ca n ' t be computed weaken the pile ' s ability of bear load
鉆孔灌注樁施工技術在高層建築、大跨度、大承載力的基礎工程中得到了廣泛的應用，但是，地層土壤存在孔隙、土壤具有可壓縮性、孔底存在沉渣等許多不可明確計算的因素，使樁的承載力存在不同程度的削弱，實際承載力與設計值有較大出入。The results of the engineering practice showed that, in the geological conditions suitable for boring with traditional percussion drills, boring with percussion drills in conjunction with post grouting technique can effectively solve the problem of the large amount of dreg deposited at the bottom of the bore, thus reducing the settlement and improving the bearing capacity of the foundation piles
工程結果表明，在適宜選用傳統沖擊鉆機成孔的地質條件下，採用后壓漿技術與沖擊鉆機成孔相結合的施工方法能有效地解決孔底沉渣量過大的難題，減少沉降量，提高基樁承載力。分享友人
