Underwater concrete filling pile (wall) over-filling concrete pretreatment device and underwater concrete filling pile (wall) over-filling concrete pretreatment method
The invention relates to an underwater concrete cast-in-place pile (wall) over-pouring concrete pretreatment device and method, and belongs to the technical field of civil engineering construction. After pile foundation concrete pouring is completed, cement in over-pouring concrete is removed through the device by means of mud, a mud pool and a mud pump used in pile foundation construction, and the over-pouring concrete becomes a low-strength mixture of gravel, a small amount of sand and mud. And the effect of simply, economically and efficiently treating the over-poured concrete is achieved. The device comprises a handle and a slurry nozzle, the lower end of the handle is connected with the slurry nozzle and can be upwards spliced and lengthened, a slurry inlet in the upper end of the slurry nozzle is flexibly connected to a slurry pump in a slurry pool through slurry, and a slurry spraying opening is formed in the lower end of the slurry nozzle.
本发明涉及一种水下砼灌注桩（墙）超灌砼预处理装置及方法，属于土木工程施工技术领域。在桩基砼灌注完成后，利用本装置并借用桩基施工中使用的泥浆、泥浆池、泥浆泵清除超灌砼中的水泥，使之成为碎石、少量砂和泥浆的低强度混合物。达到了简单、经济、高效率处理超灌砼的效果。本装置包括手柄、泥浆喷头，手柄下端与所述泥浆喷头连接，向上可拼接接长，泥浆喷头上端进浆口通过泥浆软连接至泥浆池内的泥浆泵上，下端为喷浆口。
