The utility model relates to a plastic inspection well for a drainage system of a substation. The utility model comprises a well seat, a well bore and a well cover. The well bore is a bellows structure, and a saddle joint is respectively arranged on the front and side of the well bore. The saddle joint is threaded with the well bore, and each saddle joint is connected with a drainage pipeline in one direction. The well bore is provided with three convex connecting ports, which are inverted T-shaped as a whole. The well bore is installed on the upper convex connecting port of the well bore, and the well bore is arranged on the convex connecting port of the well bore A ring of sealing ring is arranged at the installation place of the well seat; a horizontal bellows is connected at the convex connecting port on the left side of the well seat, and a ring of sealing ring is also arranged at the installation place of the horizontal bellows and the well seat; a saddle joint is also arranged at the convex connecting port on the left side, and a saddle joint is also arranged on the horizontal bellows; the convex connecting port on the right side can be connected with a right horizontal tube; the well cover is arranged at the shaft Top. Flexible connection is adopted at the joint of each pipe orifice of the inspection well to completely eliminate the leakage and leakage of rainwater and sewage and prevent the secondary pollution of groundwater.

一种变电站排水系统塑料检查井
本技术属于变电站设备
,具体为一种变电站排水系统塑料检查井。
技术介绍
目前大部分变电站均采用有组织的暗管排水的方式,传统的检查井主要是采用砖砌井和钢筋混凝土井。砖砌检查井是通过红砖堆砌和水泥抹面而成,应用历史最悠久,有几千年历史,但是由于砖砌检查井使用的粘土砖大量毁坏土地资源,检查井不能全天候施工,且施工周期长,占地面积大,易渗漏造成地下水源二次污染,维修较频繁,目前世界各发达国家以及我国主要大中城市纷纷出台措施,限制和禁止使用砖砌检查井。钢筋混凝土井是钢筋塑形和水泥浇筑而成,主要包括以下几种形式:混凝土砌块式、预制拼装式、现场浇筑式、现浇及预制组合式。新式的钢筋混凝土检查井能够避免传统砖砌检查井的一些缺点,在施工周期、结构强度、快捷拼装、受施工人员专业技术水平影响等方面具备相对优势。但是钢筋混凝土检查井有些缺点是不可避免的,如(1)预制的混凝土检查井较为笨重,要求必须有机器吊装,对现场地形要求较高,开挖面积大,机器费用较大。(2)现浇混凝土检查井受限制条件较多(如:天气、机器、施工人员专业技术水平等)。(3)混凝土检查井一般采用刚性连接,连接处易脱落,导致污水泄漏,特别是和塑料管道连接,会造成不均匀沉降从而造成管井接口处断裂。(4)由于检查井接入的干管,支管的口径,数量,方向,标高的变化因素多,混凝土检查井很难实现工厂规模化生产解决,总体质量不好控制。(5)混凝土检查井维修不便,后期支管接入问题不好解决。(6)相对于其他形式的检查井,现场浇筑混凝土检查井造价较高;在多数市政工程施工时,如果当天不能回填,所造成的经济损 ...
