| 中文摘要: |
| 水泥粉喷桩复合地基中,水泥均匀度是影响水泥土质量的重要因素。现场试验及实际工程的施工研究表明:在施工操作中,水泥均匀度主要取决于喷粉速度,切土厚度和搅拌次数。因此.保证水泥均匀度必须注重施工工艺设计,合理确定钻杆提升(下钻)速度,并注意与钻杆转速、钻头形式和尺寸、水泥掺量、桩体尺寸、喷搅次数等参数的对应关系。 |
| 英文摘要: |
| In compounding foundation of cement powdered jet pile,the uniform degree of cement is very important norm whick influences the quality of cement clay.Studies about site testes and practical projects show that in construction operations,the uniform degree of cement depends on such factors as velocity of spraying powder,thickness of chopping clay and agitating times.Accordingly,in order to stipulate the uniform degree of cement,you must regard following points.Firstly,you must see to comstruction technics designing.Secondly,you must reasonably ascertain jackrod hoisting or down speen.Last,you must mind out homologous relations to such parameters as jackrod totating velocity, forms and sizes of broaches,quantity of cement jumbling,size of piles,and spraying and mixing times. |
