    二次防墜落裝置(網蓋)解決城市井蓋吞人的安全問題

        近年來,由于井蓋缺失引起的致人傷亡事件在國內屢有發生,究其原因,就是因為檢查井沒有安裝防墜落裝置所致,依據住建部第311號公告要求,結合省內情況,從即日起要求我省新建項目檢查井必須安裝帶有雙層防墜落裝置的檢查井蓋,同時對老舊檢查井改造安裝防墜落裝置。

    二層防墜落裝置(網蓋)的安裝說明

    每個網格有六個掛件組成,先在井座內沿定六個等位點,在等位點上鉆孔,鉆孔方法相鄰的兩孔要向左右相對斜鉆45°,用眼磨鉆磨出掛件槽,要把掛件鑲嵌平整,安裝時一定要把螺絲擰緊,安裝方法簡單、快捷、安裝技術要領易掌握,安裝好后網格與原來蓋成一體,承載力強,防倒灌水流沖擊,不會墜落大塊物體,所有組件都是防腐材質,防腐性能好。

    安裝使用工具:手電鉆、眼磨鉆各一把、十四扳手兩把。

    一、施工方法:我們采用在井圈內沿鉆孔,采用冷彎技術掛鉤。

    可以在目前市場上多種老舊井蓋上加裝。

    二、拆卸方法:拆卸簡單方便,解決了市場上實際存在的需要檢查時破壞性拆除的勞民傷財的做法。

    三、使用壽命長:所有組件全部是防腐材料,經中國科學院金屬研究所金屬腐蝕與防護國家重點實驗室(沈陽)測定,我公司二次防墜落裝置(網蓋)壽命長達8―10年。

    四、承載重:一般要求防墜落裝置的承載是100公斤,我公司產品承載經實驗可達到一噸,可以有效防墜落。
