Embodiment 1
[0023] like figure 1 As shown, the present invention proposes a mud treatment device for building pile foundation construction, including: a clean water tank (not shown in the figure), a water pump (not shown in the figure), a spring 1, a sand-water mixing pipe 2, a screen 3, a mud Transfer device 5 , support frame 6 , vibrator 7 , mud pump 8 and mud pool 9 .
[0024] Specifically, a clean water tank is provided beside the sand-water mixing pipeline 2, and the clean water tank is used for buffering clean water.
[0025] The input end of the water pump is communicated with the clean water tank to extract clean water.
[0026] The position of the input end of the sand-water mixing pipe 2 is higher than the position of the output end, and the overflow hole provided on the top of the casing 4 and the output end of the water pump are both connected to the input end of the sand-water mixing pipe 2, so that the sand-water mixing pipe 2 Internal mixing, so that the adhered mud on th...
Embodiment 2
[0042] The difference between this embodiment and Embodiment 1 is that in order to facilitate the removal of residual drill ballast on the screen 3 , a movable plate 35 and a driving device 36 are provided on the screen 3 .
[0043] like Figure 4 As shown, specifically, the screen 3 is provided with a movable plate 35 that can slide in the drain groove of the screen 3, and a driving device 36 for driving the movable plate 35 is provided on the screen 3, and when in the filtering state The movable plate 35 is located on the end face of the input end of the screen 3 .
[0044] like Figure 4 as well as Figure 5 As shown, in order to realize the driving of the movable plate 35 by the driving device 36 . Since the drill ballast on the screen 3 can automatically slide off under the action of gravity, but there is still residual drill balls on the screen 3, and long-term accumulation will cause the screen 3 to be blocked. Therefore, a movable plate 35 and a driving device 36 ar...

Abstract
The invention provides a mud treatment device for building pile foundation construction. The mud treatment device comprises a sand pump for pumping mud and drilling slag out of a drilled hole, a clean water tank for storing clean water, a water pump, a sand and water mixing pipeline, a screen and a net rack, wherein the input end of the water pump is communicated with the clean water tank, so that clean water can be pumped; the position of the input end of the sand and water mixing pipeline is higher than that of the output end of the sand and water mixing pipeline, the output end of the sand pump and the output end of the water pump are both connected to the input end of the sand and water mixing pipeline; the screen is of a circular-arc-shaped structure, the input end of the screen is located below the output end of the sand and water mixing pipeline, the position of the input end of the screen is higher than that of the output end of the screen, and an included angle between the axis of the screen and the horizontal line is 20-30 degrees; the net frame comprises at least two diagonal rods, the upper end of each diagonal rod is fixed with the edge of the screen, and the lower end of each diagonal rod is connected to a vibrating plate. The med treatment device has the following benefit: automatic discharge of drilling slag is realized after mud separation.
Description
technical field [0001] The invention relates to a device used in pile foundation construction, in particular to a mud treatment device for building pile foundation construction. Background technique [0002] With the development of the economy and the acceleration of urbanization, the construction industry is developing more and more rapidly, and more and more buildings are built on complex foundations. Pile foundation engineering has become one of the most commonly used forms of construction. For complex foundations such as weak foundations, boulders, or super-deep and super-diameter pile foundations, the hole-forming process of mechanical mud retaining wall is more and more used as a mature technology for construction. In the prior art, during construction, a mud pool is set on the site plane for mixing mud or as a circulating mud pool. With the drilling footage, the mud index in the borehole is repeatedly measured, and a mud pump is used to replenish the mud into the bore...
