    產品說明

    雙層防護井蓋適用于城市主要道路和大型貨車通行較多的路段                                              1、井座:底部最大外圓直徑 Φ1050mm,高180mm,人孔(凈開孔)直徑 Φ700mm。底座上開有對稱的8個用于與蓋板固定的長 形孔,可防止移位。上邊緣設置有專用開啟口(用于冬季承載蓋與井座間結冰凍結的情況下,可用撬棍插入此口撬動承載蓋,便于開啟),可分別安裝直徑 Φ790mm承載蓋和740mm 黑龍江省正赫科技防護蓋。

     2、承載蓋:直徑 Φ790mm,邊緣厚度為50mm。該井蓋采用復合增強工藝制作,內置特制鋼骨架,遇到超載或超強沖擊,最嚴重只能是井蓋出現裂紋變形,也不會發生突然“破碎塌落” 的現象,給維修和更換提供預警和機會,可最大限度的避免交通事故的發生,保護車輛和行人的安全。

    3、防護蓋:分子蓋和網蓋兩種。

    (1)、子蓋:子蓋外形與承載蓋相似,比承載蓋薄。安裝在承載蓋下層。給水井、消防井、通訊井、電力電纜井、燃氣井上加裝子蓋,其功能一是保溫和對井內設施防護作用;二是

    在承載蓋意外損壞或丟失的情況下可有效防止行人意外墜入井內保護行人安全。

    (2)、網蓋:外形如上圖安裝在承載蓋下層。排水井、污水井上加裝網蓋,一是在承載蓋意外損壞或丟失的情況下可有效防止行人意外墜入井內,保護行人安全;二是遇到暴雨道路 

    積水過多時,可直接打開承載蓋排水,而二層網蓋在不影響水的情況下, 有效的防止行人意外墜入井內過較大雜物沖入井內造成淤塞。
