一种锁口管顶拔孔道的封堵装置
本技术涉及建筑地连墙接口施工
,具体来说,涉及一种锁口管顶拔孔道的封堵装置。
技术介绍
在采用锁口管接缝形式的地连墙混凝土的浇筑生产过程中,地连墙一端接缝与既有地连墙混凝土连接,另一端接缝采用锁口管作为临时模板。锁口管为圆柱形铁柱,直径与地连墙厚度相同,在混凝土初凝后,该锁口管即可根据混凝土浇筑速度及时间不断起拔,锁口管的起拔采用专用千斤顶顶拔装置,该顶拔装置横跨地连墙放置在地连墙导墙地面上锁口管位置,通过横穿锁口管中心的水平穿杆向上顶拔锁口管,因此锁口管中心必须预留水平穿杆使用的孔道,即顶拔孔道;由于顶拔装置的顶拔设备行程一般在1.5m左右,因此锁口管中心每隔1.2~1.5m必须预留一道顶拔孔道,常规地连墙至少深35m,一条锁口管至少得有二十多道顶拔孔道。锁口管在水下作为临时模板使用时顶拔孔道如不加以封堵,则混凝土及泥浆容易充满孔道并凝固,影响顶拔过程中顶拔孔道的正常使用,工地上常规采用土工布条或编织袋布条缠绕成团予以填充堵塞,由于泥浆混合水泥浆液的渗透,导致掏取布条十分困难,一般一道孔道的布条掏取时间顺利的要五六分钟,不顺利 ...
