Abstract
A bored pile sand filter, sand filter comprises the housing that the cavity cylinder that is communicated with by communicating and cavity cone form, and in cavity cylinder side, is provided with inlet pipe, bottom surface is provided with outlet pipe, on the top of housing, ball valve is installed as sand export.The length of described cavity cone is 3 times of cavity cylinder length.Described outlet pipe diameter is greater than the diameter of inlet pipe.The utility model provide for bored pile sand filter, make simple, easy to operate, device can reuse, filter sand speed is fast, cost is low, has guaranteed filter sand quality simultaneously.
Description
Technical field
The utility model relates to a kind of sand filter device, is specifically related to the device that a kind of bored pile sand factor is controlled.
Background technology
On-the-spot at bored pile construction, in bored pile, sand content in mud is controlled and is repeatedly circulated to control sand factor with mud in mud in mud pit and drilled pile hole, and this mode clear hole time is long, and sand factor is controlled and is difficult to reach normal value, affects concrete pouring quality.Therefore, at mud circulating system, enter in slurry system to increase a kind of sand filter, control and pass into drilled pile sand content in mud, reach the object in fast clear hole, guarantee concrete pouring quality.
Summary of the invention
In order to overcome the shortcoming existing in above-mentioned prior art, it is a kind of for bored pile sand filter that the utility model provides, and this installs easy operation, economical and practical, and filter sand fast reaches the object of keyhole filling pile slurry sand factor.
The purpose of this utility model is achieved in that a kind of bored pile sand filter, sand filter comprises by the cavity cylinder of the connection that communicates and the housing that cavity cone forms, in cavity cylinder side, be provided with inlet pipe, bottom surface is provided with outlet pipe, on the top of housing, ball valve is installed as sand export.
The length of described cavity cone is 3 times of cavity cylinder length.
Described outlet pipe diameter is greater than the diameter of inlet pipe.
The utility model provide for bored pile sand filter, make simple, easy to operate, device can reuse, filter sand speed is fast, cost is low, has guaranteed filter sand quality simultaneously; The length of cavity cone is that 3 times of cavity cylinder length make mud have sufficient blending space; Outlet pipe diameter is greater than the diameter of inlet pipe, mud forms whirlpool by inlet pipe fast rotational in cavity, sandstone in mud is separated with mud, under gravity and centrifugal action, sandstone is emanated downwards, be settled down to sand filter bottom, mud is discharged by grout outlet, opens ball valve sandstone and discharges, and reaches filter sand object.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Structure of the present utility model is as shown in Figure 1: a kind of bored pile sand filter, sand filter comprises by the cavity cylinder 3 of the connection that communicates and the housing that cavity cone 4 forms, in cavity cylinder 3 sides, be provided with inlet pipe 2, bottom surface is provided with outlet pipe 1, on the top of housing, ball valve is installed as sand export 5.The length H of described cavity cone 4 is 3 times of cavity cylinder 3 length h.Described outlet pipe 1 diameter is greater than the diameter of inlet pipe 2.
Operating principle of the present utility model is as follows: before the work of this sand filter, sand filter is placed on the slope, makes its cavity cylinder 2 a little more than cavity cone 4.During work, close ball valve, mud enters after cavity fast rotational in cavity by inlet pipe 2, and sandstone is settled down to sand filter bottom, and mud is discharged by grout outlet 1, opens ball valve sandstone is discharged from sand export 5, reaches filter sand object.
Claims (3)
