  3. 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。
  4. Abstract : by means of metallographical examination and sem, the microstructure characteristics, macro - and microfractographs of the brittle broken wheel hull bolt of bj212 automobile have been studied. the results show that the thin - headed screw, with excessively deep carbonitriding layer and hardening layer, has less resistance to brittle fracture in the thin area of its head. at the root of the head connecting the stem, a tensile stress may emerge owing to the non - even quenching stress. those are the two reasons for low torque fracture of bolt

    文摘:藉助金相、掃描電鏡等手段對低扭矩脆斷的bj212汽車輪殼螺栓的金相組織特徵，宏觀和微觀斷口形貌等進行了研究，結果表明：這種頭部薄的螺栓，滲層和淬透層過深，使頭部薄區脆斷抗力降低，在頭部與桿的根部，由於淬火應力不均勻導致根部產生拉應力，均是導致螺栓低扭矩斷裂的原因。
