来源:http://www.kpp647.com添加时间:2016-12-12 18:01:20

制作检查井盖等产品所使用的原材料应为QT500-7球墨铸铁,球化率大于90,球化级别达三级以上,含磷量<0.08,含硫量<0.05。
The raw materials used to make products such as manhole cover should be QT500-7 ductile iron, spheroidization rate is greater than 90, the nodularity is more than three, P < 0.08, the sulfur content of less than 0.05.
2、井盖与井座表面应铸造平整光洁,花纹、标记及字标清晰无缺损,无多余部分、无毛刺、无锋利边缘、无曲翘变形、无龟裂,不得有裂纹或影响检查井使用性能的冷隔、鼓包、砂眼、缩松等等缺陷,不得补焊。
2, the well cover and the well seat surface should be smooth, casting, pattern marking and word mark clear without defect, no excess, no burr, no sharp edges, no warping deformation, no cracking, no cold shut, bulge, trachoma, shrinkage and other defects such as cracks or affect the use of inspection wells performance no, welding.

3, should cover the use of socket type structure, the lower part of the inner wall and the well to well frame is tightly matched with the three points should be used; the spring arm locking device to prevent accidental opening, stability and safety, prevent beating, displacement, reduce the vibration by impact significantly, greatly reducing the road surface covers the surrounding fragmentation may prevent noise. Should be used to prevent accidental closure of the safety hinge, required for stainless steel hinge shaft and diameter of not less than 14mm, so that the connection is more solid, the overall hidden in the flange type below the surface to enhance the security performance.
4、井盖与井座间的缝宽应符合如下要求:检查井盖净宽JKmm ≥600、缝宽a=a1+ a2 ㎜允许偏差范围8+2-4;检查井盖净宽JKmm <600、缝宽a=a1+ a2 mm 允许偏差范围6±2。
4, the well cover and the well seat width shall comply with the following requirements: manhole cover width JKmm = 600 a=a1+ A2 mm, width allowable deviation range of 8+2-4 is JKmm, <600; manhole cover width of a=a1+ A2 mm 6 + 2 allowable deviation.
5、井座支承面的宽度应符合如下要求:
5, the width of the bearing surface of the well should meet the following requirements:
5.1检查井盖净宽JKmm≥600、井座支承面宽度6mm ≥20;检查井盖净宽JKmm<600、支座支承面宽度6mm≥15;
The 5.1 is JKmm more than 600 manhole cover and base bearing width 6mm = 20; the manhole cover is JKmm<600, bearing surface width 6mm = 15;
5.2井盖的嵌入深度,重型检查井应不小于40mm,防滑花纹:凸高3mm;
The embedded depth of 5.2 wells, heavy inspection wells should be not less than 40mm, non skid tread: convex high 3mm;
