This muddy water agitating device also includes slurry outlet, high pressure water injection mouth, and slurry outlet is arranged on the side of cylinder, and high pressure water injection mouth is positioned at the top of cylinder；Shaft is positioned at the central authorities of cylinder, is provided with two groups of stirring sheets.
Further, described shaft is seamless steel pipe, and its end is provided with plug, to prevent mud from entering in shaft, it is ensured that the mixing effect of shaft.
Further, described often group stirring sheet is provided with three, and stirring sheet circumference is distributed on shaft.
Further, the length of described stirring sheet is arranged with the minor diameter fit of cylinder, to improve stirring scope to greatest extent, improves the effect of stirring.
Further, described slurry outlet is connected with sludge pump, and described high pressure water injection mouth is connected with intake pump, draining pump and spoil disposal stock pump cooperating, controls the water of inner barrel, earth pressure balance.
Further, described muddy water agitating device also includes access hole, and it is arranged on the bottom of cylinder, to facilitate maintainer check shaft and keep in repair.
Further, the profile of described access hole is square, and it is by blind plate sealing.
This utility model beneficial effect:
The muddy water agitating device that this utility model provides is applicable to underground piping cable laying operation field, it is rational in infrastructure, its with earth pressure balanced push-bench with the use of, muddy water is used to be unearthed form, improve push-bench rear to be unearthed efficiency, effectively control water, earth pressure balance, prevent protuberance or the sedimentation on ground, it is ensured that the efficiency of construction of push-bench and construction quality.
