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。Compared with the mud on wall form hole technology, clash stake technology or vibration sink pipe technology used in complex foundation stake forming, it has advantages of no vibration, no pollution, and no noise. in addition, since the concrete pressed into the drill stem sent vibration free concrete to the pump, so it is eas y to ensure the quality of the stake body. compared with the mud on wall and dry work form hole technology, the side obstruction and end obstruction of screw drill press concrete stake have all been accordingly improved, the weight bearing is better, and the transmutation of the complex foundation is less
其中，螺旋鉆孔壓灌混凝土成樁技術自研製以來，已在多項復合地基工程中進行了應用，較好地解決了軟弱地層成孔困難的問題，適應地質條件范圍廣，成樁速度較快，工期短、工效高；與復合地基成樁時的泥漿護壁成孔工藝、振沖樁工藝或振動沉管工藝施工比較，具有無振動、無污染、無噪音的優點；另外，壓入鉆桿內的混凝土為泵送免振混凝土，因此樁體質量易於保證；與泥漿護壁和干作業成孔工藝相比，螺旋鉆孔壓灌混凝土成樁的側阻和端阻都有相應的提高，樁的承載性能較好，復合地基的變形較小。Based on the review of petroleum exploration in the south margin of junggar basin in the past half century, the difficulties of piedmont exploration in different phases are summarized as follows : complex structures : large variability in reservoir quality and difficulty in predicating its scale ; inaccurate image of seismic data ' s migration processing in complete trough structural belts ; requirement for high technology of drilling, etc
