鉆桿振動 的英文怎麼說
中文拼音 [zhēngǎnzhèndòng]
鉆桿振動
英文
rod vibration-
Field operation shows that, by using the hydrodynamic propulsor, not only the penetration rate is increased, the vibration of the bit and drill stem is reduced as well, thereby the service life of the bit is extended
1995 - 1998年井下液力推進器在大港油田等地區不同區塊20餘口井上施工的實踐證明，使用這種推進器不但可以提高機械鉆速，而且減輕了鉆頭和鉆桿的振動，進而延長了鉆頭壽命。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。
