球墨铸铁井盖中井圈检测的方式有哪些?

来源:http://www.jnwszy.com添加时间:2022-02-10 19:05:00

井盖外型要求:无显著的焊接缺陷。用常用工具检验井圈直徑,操纵范畴直徑在井盖规格,深层40mm,地脚螺栓孔要用专用型工装夹具逐检。配合及喷涂检验型胶圈与井圈配合,胶圈放到T型槽要平,不较长或稍短,粘合坚固,配合空隙不超毫米。井盖与井框配合拼装要平,不摇晃、无响声,盖与框高矮配合不超过毫米。型胶圈先粘坚固,再喷涂,井盖(圈)喷涂匀称,无锈迹。

Appearance requirements of well cover: no significant welding defects. Check the diameter of the well ring with common tools. The diameter of the operation scope is within the specification of the well cover, with a depth of 40mm. The anchor bolt holes shall be checked one by one with special tooling fixtures. Fit and spray the inspection rubber ring with the well ring. The rubber ring shall be flat in the T-groove, not longer or shorter, firmly bonded, and the fit gap shall not exceed mm. The well cover and well frame shall be assembled flat without shaking and noise, and the height of the cover and frame shall not exceed mm. The O-ring shall be firmly adhered before spraying. The well cover (ring) shall be sprayed evenly without rust.

针对球墨铸铁井盖表层的颜色,应与路面颜色维持统一,且井盖的表层要有突起的地面防滑纹路,突起的高宽比操纵在3-8mm中间。那样不但能够避免摔倒,另外有利于排水管道,降低井盖面积水流量。针对球墨铸铁井盖与井座的表面中间应运用相对的机械加工制造方式开展解决。要确保他们中间触碰的稳定性及可信性,在车子历经时,应不会有跳跃状况。如果是金属材料类的井座支撑点面,其与井盖间,应设计方案有消声避震的原材料,且这种原材料应与井盖中间有靠谱联接。

The color of the surface layer of the nodular cast iron manhole cover shall be consistent with the road color, and the surface layer of the manhole cover shall have raised ground anti-skid lines, and the height width ratio of the protrusion shall be controlled in the middle of 3-8mm. In addition, it can not only reduce the drainage area of the well cover, but also reduce the drainage area. Relative machining and manufacturing methods should be used to solve the problem between the surface of nodular cast iron well cover and well seat. They should have stability when they jump, and they should not touch in the middle. If the well seat support point surface is made of metal materials, the raw materials for noise elimination and shock absorption shall be designed between it and the well cover, and such raw materials shall be reliably connected with the middle of the well cover.

T型胶圈与井圈配合,胶圈放到T型槽要平,不较长或稍短,粘合坚固,配合空隙不超毫米。

The T-shaped rubber ring shall be matched with the well ring. The rubber ring shall be flat in the T-shaped groove, not longer or shorter, firmly bonded, and the matching gap shall not exceed mm.

井盖与井框配合拼装要平,不摇晃、无响声,盖与框高矮配合不超过毫米。

The well cover and well frame shall be assembled flat without shaking and noise, and the height of the cover and frame shall not exceed mm.

T型胶圈先粘坚固,再喷涂,井盖(圈)喷涂匀称,无锈迹。

The T-shaped rubber ring shall be firmly adhered before spraying. The well cover (ring) shall be sprayed evenly without rust.

球墨铸铁井盖的品质不合格,因为各种原因导致一些伪劣井盖采用工程项目上,给安全性留有安全隐患。现阶段,除传统式的生铁井盖外,球墨铸铁、新式混泥土、高分子材料井盖也广泛运用。

The quality of nodular cast iron manhole covers is unqualified. Due to various reasons, some fake and inferior manhole covers are used in engineering projects, leaving potential safety hazards for safety. At this stage, in addition to the traditional pig iron manhole covers, nodular cast iron, new concrete and polymer manhole covers are also widely used.
