the foundation of diesel generators
基础的承载力要求
the load capacity requirements of foundation
基础的质量应能承载基础总值的2—5倍,对于高速机组可取较小值。
Based on the quality of infrastructure should be able to load 2-5 times the quality of the foundation, high-speed generator unit value less desirable.
基础的材料
Materials of the foundation
基础应用标号不低于450号混凝土并捣筑。混凝土由水泥、砂、碎石和水拌合后凝固而成,用6mm钢筋网做钢结构。混凝土所用的砂子要坚硬、洁净,其所含的污泥粉末不能超过总质量的5%,最好的砂子为石英砂。石子也要洁净,其大小约为5—10mm。砂子的粗细、石子的大小要搭配使用。
Application labeling is not less than 450 of the concrete. Concrete from cement, sand, gravel and water mixture after solidified form, so 6mm reinforced steel. Concrete used to the hard sand, clean, the sludge contains not more than 5% of the total powder. The best sand quartz sand. Stone also is cleaning, about the size of 5-10mm. The coarse and fine sand, gravel mix used to the size.
混凝土的配合比例
Concrete matching ratio
混泥土采用的容积配合比例(水泥:砂:石子)为:1:2:4或1:3:5或1:3: 6
These projects with the volume ratio (cement : sand : stone) : 1:2:4 or 1:3:5 or1:3:6
基础的尺寸
the size of the foundation
1) 西电的柴油发电机组,均为钢制底盘并配置高性能减振器,因此,机组的混凝土基础无需预留地脚螺孔。
the diesel generators of SDMO, both steel chassis and high-performance shock absorber configuration, therefore, Unit pores of the concrete foundation without reserve feet
2) 基础的长度和宽度,依据机组的外形的长、宽尺寸各扩放300mm左
the length and width of the foundation, according to the shape of the unit length, width up to expand the size of 300mm Left
3) 基础的深度,即混凝土基础的厚度(高度),一般以柴油机汽缸直径的3—4倍进行概算,对于小型机组也常在在100—200mm之间确定。
the depth of the foundation, just as the thickness of the concrete foundation (height), generally 3-4 times the diameter of the cylinder diesel engine for budget For small units often set in 100-200mm between.
4) 基础与地坪可以做成同一高度,也可以使基础高于地坪50—100mm,基础尽可能平整光滑,并预留排放槽,以便废水污油等及时流走。
The foundation and floor can cause the same height. above the floor can also make basic 50-100mm. formed the basis smooth as possible, and set aside emissions bay for wastewater effluent oil timely outflows.
基础的浇灌
the foundation casting
1)浇灌前应根据基础的尺寸准备好模板及钢筋结构网。
2)基础的基层要夯实,基坑无积水,基础要一次捣筑完毕,在浇灌过程中间歇时间最多不超过2小时。
3)基础表面要水平、平整、养护一周后可进行安装
1) the template and the reinforced iron structure network should be ready according to the size of the foundation before casting.
2) to lay a solid foundation at the grassroots level, no water pit, a foundation to build the team finished, Intermittent time in the casting process up to more than two hours.
3) the foundation surface should be level and formation, installation is permitted a week after the conservation
机组保护接地网
机组接地网,须单独预埋,不能和其它设备共用同一接地网,接地网漏出地面扁铁端头部位须开¢10通孔
grounding protection network
units to be embedded alone, not sharing the same earth and other network equipment. End of foul ground grounding grid-iron through-hole location to be opened 10 ¢
管线预埋
1.地沟开挖尺寸为:150mmx200mm(宽x深)
2.埋入地沟套管用3.5"PVC管,1"波纹软管。
3.各种交流动力线缆、直流线、信号线缆以及须分别配穿套管。
4.铺设穿好PVC套管的管线。
5.回填地沟,要求压实且平整。
A pipeline embedded.
1)Trench excavation size : 150mmx200mm (width x depth)
2) buried in trench casing with 3.5 "PVC pipe 1 "Corrugated Hose.
3) AC power cable, DC lines, signal cables and oil tubing wear casing respectively.
4)PVC casing laying of the pipeline and fashions. 5. Backfilled trench, which formed compaction requirements下载本文
