Methods: Transurethral electric resection, electric coagulation and mitomycin C pouring after operation were all used in 24 cases. 方法:24例均采用尿道电切、电灼术,术后用丝裂霉素灌注。
Technology of Superfluid concrete pouring pile is a new construction technique, which, on the basis of continuous modifying spiral jumper, has utilized modern drill to provide fine machinery performance, developing only from dry operation completed by original jumper to wet one completed by modern drill. 超流态混凝土灌注桩工艺是在我国长螺旋钻机不断改型换代的基础上,利用现代钻机所能提供的良好机械性能,将一般长螺旋钻机只能进行干作业拓展到进行湿作业的施工新技术。
This paper, through the comparison of A scheme and B scheme, mainly studies the effect of different pouring temperature on temperature field and temperature stress field of Baise roller compacted concrete ( RCC) gravity dam during construction and operation. 本论文主要目的是通过对A、B两种施工方案,研究不同浇筑温度对百色碾压混凝土重力坝施工期及运行期温度场和温度应力场的影响。
The working range of the concrete pouring equipments on the dragon beach hydroelectric project dam is heavy, overlaps each other, it is high to build the intensity, operation is fast in speed; And often there are fogs in this area. 龙滩水电工程大坝的主要混凝土浇筑设备的工作范围很大,彼此重叠,浇筑强度高,运行速度快,并且该地区多雾。
