Some pile foundation hole-forming depth is larger, and the stratum structure is complex and changeable. In the drilling process, when encountering geological conditions such as gravel layer and karst cave, it is usually necessary to backfill clay and add stone to block.

[0038] Combined with the drawings Figures 1-2 A kind of quick separation device of silt for pile foundation construction, including high-low position different first-stage sedimentation tank and secondary sedimentation tank, under the scheme without pumping mud, first-stage sedimentation tank is higher than secondary sedimentation tank, further including separation mechanism installed between first-stage sedimentation tank and secondary sedimentation tank.

[0039] The separation mechanism of the embodiment includes a groove-shaped base frame 1 installed in the overflow port between the first-stage sedimentation tank and the secondary sedimentation tank. To ensure the sealing of the device and prevent the mud in the first-stage sedimentation tank from leaking directly from the gap between the outer frame surface of the groove-shaped base frame 1 and the overflow port, a strict sealing treatment is carried out between the two. Specifically, the outer frame surface of the groove-shaped base frame 1 is provided with a sealing baffle 10. When installing the groove-shaped base frame 1, the sealing baffle 10 can be directly inserted into the soil of the overflow port, thereby sealing the gap between the outer frame surface of the groove-shaped base frame 1 and the overflow port. This design is simple, quick and convenient to construct, and can effectively ensure the normal operation of the device.

[0040] A filter screen 2 is vertically suspended in the slot of the groove-shaped base frame 1, which mainly functions to separate sand and mud. The mud flows into the secondary sedimentation tank through the filter screen 2 and can be reused, while the sand is blocked in the first-stage sedimentation tank and can be regularly salvaged and cleaned by the operator. A vibration motor 6 is installed at the top of the filter screen 2. During the separation operation, when the vibration motor 6 is started, it will drive the filter screen 2 to vibrate. This vibration can effectively prevent the sand from clogging the screen holes of the filter screen 2, so that the filter screen 2 always maintains high separation efficiency, thereby improving the working efficiency and separation quality of the entire device.

[0041] In order to achieve the elastic support of the filter screen 2, while not directly locking the filter screen 2, a plurality of support spring plates 3 are arranged between the bottom of the outer frame of the filter screen 2 and the groove-shaped base frame 1. The support spring plate 3 not only plays a supporting role, but also leaves space for the vibration of the filter screen 2. In addition, in order to further enhance the sealing effect and avoid the direct leakage of the mud in the primary sedimentation tank from the gap between the inner frame surface of the groove-shaped base frame 1 and the outer frame of the filter screen 2, a flexible waterproof cloth 5 is arranged between the outer frame of the filter screen 2 and the groove-shaped base frame 1. The flexible waterproof cloth 5 not only plays a role in sealing the gap between the outer frame of the filter screen 2 and the groove-shaped base frame 1, but also serves as a connecting piece to form a flexible connection between the outer frame of the filter screen 2 and the groove-shaped base frame 1. This flexible connection helps the filter screen 2 to remain stable during vibration, while being able to adapt to a certain displacement and deformation, thereby improving the reliability and service life of the device. Since the above-mentioned support spring plate 3 and flexible waterproof cloth 5 do not fix and limit the filter screen 2, the vibration motor 6 can better drive the filter screen 2 to vibrate. Embodiment 2

[0042] Referring to the accompanying drawings Figures 3-4 A quick sand separation device for pile foundation construction is optimized based on embodiment one. Specifically, a vertical slot is provided on the groove-shaped base frame 1 corresponding to one side of the filter screen 2. A plug-in plate 7 is movably inserted into the slot. During the separation operation, the operator can insert the plug-in plate 7 into the slot of the groove-shaped base frame 1 to block the overflow port between the primary sedimentation tank and the secondary sedimentation tank. In this way, the mud containing sand and stones can be deposited in the primary sedimentation tank for a short time, and after the deposition is completed, the plug-in plate 7 is pulled up, thereby further improving the effect of sand separation.

[0043] As shown in the accompanying drawings Figure 3 In order to facilitate the operator to perform the plug-in operation, a strip-shaped slot is designed at the top of the plug-in plate 7. This design detail makes it more convenient and labor-saving for the operator to plug in and pull out the plug-in plate 7, thereby improving the efficiency and convenience of the operation. Embodiment 3

[0044] In combination with the accompanying drawings Figure 2 and the accompanying drawings Figure 5 A quick sand separation device for pile foundation construction is improved in the cleaning function of the filter screen 2 based on embodiment 1 or 2. Specifically, a cleaning brush 8 is slidably connected to the filter screen 2, which mainly serves to clean the screen holes, prevent the screen holes from being blocked, and ensure the efficient operation of the separation device.

[0045] The structure of the cleaning brush 8 is designed as follows: it includes a U-shaped frame 8-1 which is arranged on the outer frame of the filter screen 2. The top and bottom of the outer frame of the filter screen 2 are provided with sliding grooves. Correspondingly, sliding blocks 8-2 are installed on the U-shaped frame 8-1 at positions corresponding to the sliding grooves, and the sliding blocks 8-2 are in sliding connection with the corresponding sliding grooves. In this way, the U-shaped frame 8-1 can slide left and right along the filter screen 2 through the sliding blocks 8-2.

[0046] On the inner walls of the U-shaped frame 8-1, brush 8-3 is installed. When the U-shaped frame 8-1 slides left and right along the filter screen 2, the brush 8-3 also slides left and right along the filter screen 2. In this way, the brush 8-3 can effectively clean the screen holes of the filter screen 2, preventing sand and gravel from accumulating on the side of the filter screen 2 corresponding to the primary sedimentation tank, thereby further improving the performance of the separation device.

[0047] In order to facilitate the use of the cleaning brush 8 by the operator, a handle 8-4 is installed on one side of the U-shaped frame 8-1. The operator can directly push the U-shaped frame 8-1 through the handle 8-4, or use an extension rod with a hook (not shown in the figure) to push the U-shaped frame 8-1 by hooking the handle 8-4. This design makes the cleaning operation more flexible and convenient, improving the maintenance efficiency of the equipment. Embodiment 4

[0048] In combination with the accompanying drawings Figure 1 A kind of quick separation device of silt for pile foundation construction, on the basis of any one of embodiments 1 to 3, the fixing mode of groove base frame 1 is improved.Specifically, multiple steel pegs 9 are arranged at intervals at the bottom of the groove base frame 1.

[0049] In actual use, the operator can drive the steel peg 9 into the land between the overflow port of the primary sedimentation tank and the secondary sedimentation tank. In this way, the steel peg 9 can firmly fix the groove base frame 1 in the overflow port, ensuring its stability during work. This fixing method is not only simple to install, but also efficient and reliable, greatly improving the field adaptability of the equipment.

[0050] In addition, in order to further improve the vibration effect of the filter screen 2 and ensure that its screen holes are not blocked, mounting brackets 4 for installing vibration motors 6 are provided at both ends of the top of the filter screen 2. That is, vibration motors 6 are installed at both ends of the top of the filter screen 2. In this way, the vibration effect of the filter screen 2 is improved, ensuring that its screen holes are not blocked. The smooth separation of mud and sand is ensured.
