适用范围Scope of use

刚性防水套管适用于管道穿墙处不承受管道振动和伸缩变形的构(建}筑物,对于地震设防要求的地区,如采用刚 性防水套管,应在进入池壁或建筑物外墙的管道上就近设置柔性连接,A型适用于钢,B型适用于球墨铸铁管。

Rigid waterproof starve is suitable for structures (buildings) where pipelines do not bear vibration and axpansion deformation of pipelines through walls. For areas requiring seismic fortification, if rigid waterproof sleeve Is used, flexible connections should bs Installed near pipes entering pool walls or building exterior walls. A type is suitable for steel and B typa Is suitable for ductile iron pipes.


说明:1套管穿墙处如遇非混凝土墙壁时,应改为混凝土墙壁,其浇注范围应比翼环直径(AD43型。3)200,而且必须将套管 一次浇固于混凝土墙内匸套管内的填料应紧密捣实。

2 穿管处混凝土墙厚应不小于200,否则应使土墙壁一边或两边加厚。加厚部分的直径至少为D4+200

3 焊接结构尺寸公差与形位公差按照JB/T500.3-1998执行。焊接采用手工电孤焊,焊条型号E4303,牌号J422焊缝坡口的基本形 式与尺寸按照GB985-88执行。

Explanalloni 1. When the casing penetrates the wall, it should be replaced by concrete wall. Ils casting range should be 200 times larger than the diameter of wing ring (A-D4 or B-D3), and lhe casing must be fixed in the concrete wall once. Packing in casing should be compactly tampered.

2. The thickness of concrete wall should be no less than 200 at the piercing point, otherwise one or both sides of the earth wall should be thickened. The diameter of the thickening part is al least D4+200.

3. Dimension tolerance and shape tolerance of welded structure shall be carried out in accordance with JB/T500.3-199B. Welding adopts manual arc welding, electrode type E4303, brand J422. The basic form and size of weld groove shall be carried out in accordance with GB985-88.
