          球墨鑄鐵井蓋如何送檢?大家對球墨鑄鐵井蓋的井圈開展查驗的情況下,能夠以內圈的口槽的部位置放一個T型的密封膠條,產生一個橡膠圈,可以非常好的避免井蓋的跑、跳,還會繼續提升井蓋與內城圈口的面積,增加符合及其觸碰的總面積。球墨鑄鐵井蓋的表層選用的是十字花棱三角形的紋路,能夠具有非常好的的實際效果。

          How to send nodular cast iron manhole cover for inspection? When the well ring of the nodular cast iron well cover is inspected, a T-shaped sealant strip can be placed at the mouth groove of the inner ring to produce a rubber ring, which can well avoid the running and jumping of the well cover, continue to improve the area between the well cover and the inner city ring, and increase the total area in line with and touched. The surface of nodular cast iron manhole cover adopts the pattern of cross flower edge triangle, which can have a very good practical effect.

          球墨鑄鐵井蓋怎樣復檢?

          How to recheck nodular cast iron manhole cover?

          1、外型:無顯著的焊接缺陷。

          1. Appearance: no significant welding defects.

          2、用常用工具檢驗井圈直徑,操縱范疇直徑在井蓋規格,深層40mm,地腳螺栓孔要用專用型工裝夾具逐檢。

          2. 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.

          球墨鑄鐵井蓋配合及噴涂檢驗

          Fitting and spraying inspection of nodular cast iron manhole cover

          1、T型膠圈與井圈配合,膠圈放到T型槽要平,不較長或稍短,粘合堅固,配合空隙不超毫米。

          1. 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.

          2、井蓋與井框配合拼裝要平,不搖晃、無響聲,蓋與框高矮配合不超過毫米。

          2. 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.

          3、T型膠圈先粘堅固,再噴涂,井蓋(圈)噴涂勻稱,無銹跡。

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

          鑄鐵井蓋的品質不合格,因為各種原因導致一些偽劣井蓋采用工程項目上,給安全性留有安全隱患?,F階段,除傳統式的鑄鐵井蓋外,球墨鑄鐵、新式混泥土、高分子材料井蓋也廣泛運用。

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

          以下是球墨鑄鐵井蓋標準規范:

          The following are standard specifications for ductile iron manhole covers:

          a、井蓋原材料選用球墨鑄鐵井圈直徑密封性范疇為正負極2mm,井蓋與井圈高矮配合精密度為正負極1毫米,配合空隙為3mm。

          a. The raw material of the well cover is nodular cast iron, the diameter of the well ring is 2mm, the height matching precision of the well cover and the well ring is 1mm, and the matching gap is 3mm.

          b、井圈井蓋抗壓強度超過500N/立方毫米,硬度測試方法為HB190-230。井蓋耐壓達到住建部CJ/T3012-93《鑄鐵檢查井蓋》的國家標準要求,超重型井蓋耐壓360KN,輕形井蓋210KN。

          b. The compressive strength of well ring and well cover exceeds 500N / cubic mm, and the hardness test method is hb190-230. The pressure resistance of well cover meets the national standard requirements of CJ / t3012-93 cast iron inspection well cover of the Ministry of housing and urban rural development. The pressure resistance of super heavy well cover is 360kn and that of light well cover is 210kN.

          c、T型橡膠圈選用三元乙丙膠,性能參數超重型GB-7529-87國家行業標準。

          c. The T-shaped rubber ring is made of EPDM, and the performance parameters are super heavy gb-7529-87 national industry standard.

          d、防盜作用是根據井座固定不動軸與井蓋聯接,另一側用銷具固定不動此方式來進行,具備堅固的防盜和抗汽蝕、切溝。

          d. The anti-theft function is carried out according to the way that the fixed shaft of the well base is connected with the well cover, and the other side is fixed with pins. It has solid anti-theft, anti cavitation and ditch cutting.
