【技术实现步骤摘要】
用于钢筒混凝土顶管注浆孔密封检测的试压装置
本技术涉及一种密封性检测装置,尤其是用于钢筒混凝土顶管注浆孔密封检测的试压装置。
技术介绍
钢筒混凝土顶管具有一定的耐腐蚀性、良好的管体和接口抗渗性,其接口采用了柔性承插式结构,可满足曲线顶进施工,因此在非开挖施工的压力给排水工程得到越来越多的使用。在非开挖施工的管节上需设置一定数量的注浆孔,将触变泥浆由注浆孔注到管外壁,以减少管外壁与周边土壤的摩擦力。既然钢筒混凝土顶管主要用于压力给排水工程,其注浆孔的封堵也应能够承受一定的内压,封堵质量也显得尤为重要。注浆后用螺纹堵头将注浆孔堵死,为测试堵头在一定水压力下的密封性,需要对其进行密封性试验,如中国专利CN201716163U公布的车载管道注浆孔水压密封性检测装置,本技术涉及管道试压装置,尤其涉及一种管道水压密封性检测装置。一种车载管道注浆孔水压密封性检测装置,它包括一个带有压力表的管状试压装置,它还包括:一个车架,车架一端设有推手;四个轮子,它们安装在车架下方;一对轴承座,它们一前一后地安装在车架上;一个回转臂,它水平设置,一端和车架通过轴承座连接在一起;它的另一端设有一个竖向套管,所述试压装置穿过套管并利用一个紧固螺钉固定。本技术能提高试压工作的效率,降低测试人员的劳动强度。但是该专利并未公开具体的检测装置,只是公开了用于装置密封性检测装置的推车。
技术实现思路
为解决上述问题,本技术提供一种结构简单、小巧、便于携带、操作简单、注水量少,可直观、快捷的检测密封效果的用于钢筒混凝土顶管注浆孔密封检测的试压装置,具体技术方案为:用于钢筒混凝土顶管注浆孔密封检测的试压装置, ...
