Description

Technical Field

[0001] The utility model relates to the technical field of anti-floating anchor piles, in particular to a small-diameter anti-floating anchor pile hole cleaning device. Background Art

[0002] The anti-floating anchor rod in the basement is one of the anti-floating measures for the structure of the building engineering. The anti-floating anchor rod refers to the structural member set up to resist the upward displacement of the building above it. It is related to the height and change of the groundwater level and is opposite to the force direction of the compression pile. At present, the anti-floating construction anchor rods are all made of special machinery. The hole is drilled by the principle of high-pressure air spiral impact drill bit to form a hole and blow away the mud residue. Due to the small diameter of the pile hole (Φ150mm~200mm), the sediment and mud in the hole cannot be blown away. The cementitious material in the pile hole of the anti-floating anchor rod is generally fine stone concrete or composite cement slurry material. Although the hole is blown and cleared with compressed air, there will always be water or mud in the pile hole after batch acceptance. If the cement-based material of the anchor pile is directly poured without eliminating the accumulated water, the anchor rod forming quality will inevitably be unqualified or the anchor rod will fail. The construction quality of the anti-floating anchor rod can be improved by thoroughly cleaning the mud in the small-diameter anti-floating anchor pile.

[0003] In view of this, according to actual needs, it is necessary to thoroughly and effectively clean the mud in the small-diameter holes while avoiding damage to the inner wall of the pile hole to ensure construction quality. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a small-diameter anti-floating anchor pile hole cleaning device, comprising a suction end, a negative pressure tank and a vacuum pump equipped with a motor which are connected in sequence;

[0005] The suction end includes a first tube body and a second tube body connected to each other, the length of the first tube body is greater than the depth of the anti-floating anchor pile hole and the outer wall diameter of the first tube body is smaller than the inner diameter of the anti-floating anchor pile hole, and the end of the first tube body placed in the anti-floating anchor pile hole is a straight line with a gap of 8 to 10 mm;

[0006] The negative pressure tank is provided with a feed port and a vacuum port, and the feed port and the vacuum port are connected to the second tube body and the vacuum pump respectively.

[0007] Furthermore, a particle filter is also arranged on the second tube body.

[0008] Furthermore, the materials of the first tube body and the second tube body are respectively a rigid material and a flexible material.

[0027] Example

[0028] like Figure 1 and Figure 2As shown, a small-diameter anti-floating anchor pile hole cleaning device includes a suction end 1, a negative pressure tank 2 and a vacuum pump 4 equipped with a motor 3, which are connected in sequence. A placement end is also arranged on the outer wall of the negative pressure tank 2 for placing the suction end 1. The negative pressure tank 2 is provided with a plurality of feed ports 21, a vacuum port 22, a water inlet 23 and a discharge port 24, and the feed port 21, the water inlet 23 and the discharge port 24 of the negative pressure tank 2 are provided with valves. A filter screen is also arranged at the vacuum port 22 of the negative pressure tank 2. The vacuum pump 4 is connected to the vacuum port 22 through a vacuum tube 5. A mud filter 51 is arranged on the vacuum tube 5. The filter screen and the mud filter 51 are used to prevent larger gravel and mud from entering the vacuum pump 4.

[0029] The suction end 1 includes a first tube body 11 and a second tube body 12 connected to each other. The length of the first tube body 11 is greater than the depth of the anti-floating anchor pile and the outer wall diameter of the first tube body 11 is less than the inner diameter of the anti-floating anchor pile hole 6. Such a configuration can easily place the first tube body 11 into the bottom of the anti-floating anchor pile hole 6. The end of the first tube body 11 placed in the anti-floating anchor pile hole 6 is a straight line with a gap of 8 to 10 mm. The mud can be quickly extracted under the premise of ensuring suction. The materials of the first tube body 11 and the second tube body 12 are rigid material and flexible material, respectively. For example, the first tube body 11 is obtained by pressing one end of a steel pipe into a straight line with a gap of 8 to 10 mm; the first tube body 11 can be a polyvinyl chloride (PVC) pipe. A particle filter 121 is also provided on the second tube body 12. The other end of the second tube body 12 is connected to the feed port 21 of the negative pressure tank 2. The presence of the particle filter 121 can filter larger gravel to avoid clogging the feed port 21 and the valve of the feed port 21.

[0030] The negative pressure tank 2 is also provided with a pressure gauge 25 and an observation window 26, which are used to detect the pressure in the negative pressure tank 2 and to observe the height of the absorbed material in the negative pressure tank 2, respectively.

[0031] In order to facilitate the quick movement of the entire device for rapid and effective cleaning, a moving component 7 is also provided, and the negative pressure tank 2 and the vacuum pump 4 are both provided on the moving component 7. In this embodiment, the moving component 7 is a trolley with four universal wheels and a handle.

[0032] The working process of the device of this embodiment is described in detail below.

[0033] 1. Fixedly install the negative pressure tank 2 and the vacuum pump 4 equipped with the motor 3 on the trolley;

[0034] 2. Connect the vacuum pump 4 to the vacuum port 22 of the negative pressure tank 2 through the vacuum tube 5, fix the first tube body 11 and the second tube body 12 to obtain the suction end 1, and then connect it to the feed port 21 of the negative pressure tank 2;

[0035] 3. Start the electrode to evacuate the negative pressure tank 2, and monitor the indication of the pressure gauge 25 of the negative pressure tank 2;

[0036] 4. Put the straight-shaped end of the first tube body 11 with a gap of 8 to 10 mm into the anti-floating anchor pile hole 6 that needs to be cleaned, and absorb the mud in the anti-floating anchor pile hole 6. The particle filter 121 can be shaken to identify the amount of large-grain gravel accumulated inside to determine whether to clean it. The amount of mud in the pile hole and the water inflow in the negative pressure tank 2 can also be observed to determine whether it is absorbed cleanly. The first tube body 11 in the pile hole can be pumped back and forth to ensure that the mud at the bottom of the pile hole is completely absorbed. A small amount of gravel does not affect the quality of the anti-floating anchor pile;

[0037] 5. After the pile hole is cleaned, the mud in the negative pressure tank 2 should be discharged in time, and it is determined whether to clean it according to the actual situation. If cleaning is required, first turn off the motor 3 of the vacuum pump 4, remove the mud filter 51 on the vacuum tube 5 for cleaning, and then remove the particle filter 121 on the second tube body 12 for cleaning; at the same time, open the valve of the discharge port 24 on the negative pressure tank 2 to discharge the accumulated mud, and add water through the water inlet 23 on the negative pressure tank 2 for cleaning.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
