【技术实现步骤摘要】
方形预制检查井结构
:本技术涉及一种方形预制检查井结构。
技术介绍
:目前在城市污水道或下水道等等中,都会设置预制检查井,然后目前的检查井都采用混凝土现场浇筑或砖块堆砌,采用混凝土现场浇筑不仅耗时、耗力,而且成本高,而采用砖块堆砌工作效率低、强度差,因此,上述方法均无法满足目前使用要求。
技术实现思路
:本技术的目的在于提供一种方形预制检查井结构,该方形预制检查井结构设计合理,有利于提高施工效率及提高安装的牢固性。本技术方形预制检查井结构,其特征在于:包括用方形检查井模块多层叠置而形成的矩形状,同一层的方形检查井模块相互贴近设置,相邻层的方形检查井模块在周向错位设置,所述方形检查井模块包括上平段、下平段和连接上、下平段之间间隔设置的两支撑段,所述上平段、下平段内分别嵌设有上、下钢筋,所述两支撑段体内分别设有连接上、下钢筋的中间钢筋,所述上平段、下平段的侧部分别设有凹槽和可与凹槽相互配合嵌入的凸条;所述矩形状检查井的四个角位置设有转角块,所述转角块呈弯钩型,在弯钩型转角块的上部设有外凸块,所述外凸块上设有凹陷配合槽,所述弯钩型转角块的下部两边设有外凸条和两侧外凸形成的中间凹陷,所述弯钩型转角块体内设有弯钩型钢筋。进一步的,上述层与层方形检查井模块之间铺设有两层格栅网,所述格栅网超出方形预制检查井外周壁30厘米,内侧与圆形检查井内周壁平齐。进一步的,上述方形检查井模块上设有两个纵向穿孔,以在该纵向穿孔中穿设有纵向钢筋和浇筑混凝土。本技术圆形预制检查井上平段、下平段的侧部分别设有凹槽和可与凹槽相互配合嵌入的凸条,从而使同一层中相邻方形检查井模块之间紧密贴近嵌合设置, ...
