Description

Technical Field

[0001] The utility model relates to the technical field of pipe pile cleaning, in particular to a device for cleaning the core soil of a pipe pile. Background Technique

[0002] During the construction of the floor slab, precast pipe piles need to be cored to meet the design requirements. However, the following problems exist in actual construction:

[0003] 1. During the construction process, the core of the pipe pile is often filled with soil. When embedding the steel bars, the steel bars are blocked by the soil, making it difficult to reach the preset depth. The steel bars cannot be completely embedded, often resulting in unqualified pipe pile strength;

[0004] 2. Currently, when cleaning the core of the pipe pile, generally a long rod is used to crush the soil inside the core, and then manual labor uses a long-handled spoon to clean it out. Moreover, the length of the simple tools on-site is fixed, and construction workers cannot carry out their work well. The use and operation are inconvenient, and this operation method is cumbersome;

[0005] 3. In conventional manual operations, sharp tools such as blades are also used to break the soil inside the pipe pile. However, when the soil inside the pipe pile dries up, it becomes very hard and difficult to break. Especially when the energy of the tool for breaking the hard soil is not strong, and the depth of the soil in the pipe pile is large and difficult to apply force, it leads to low cleaning efficiency. And when encountering soil with high viscosity during the cleaning process, there is no need to break it at all, but it is also very difficult to take out the highly viscous soil with a long spoon. Even when using large equipment, such as a screw conveyor, it is very difficult to clean the highly viscous soil.

[0006] Now, a simple device is needed to clean the soil inside the core of the pipe pile.

[0007] Based on this, the utility model designs a device for cleaning the core soil of a pipe pile to solve the above problems. Content of the Utility Model

At the truncated part in the middle of the two sleeved long pipes, it can be locked with a hoop or a buckle. When adjustment is needed, loosen the hoop, and after the adjustment is completed, lock it again to achieve the purpose of adjusting the length. It is necessary to ensure that the inner pipe of the cleaning rod 1 is unobstructed, which is used to place and install the water suction pipe 22 and the water spraying pipe 23. After assembly, the water suction pipe 22 and the water spraying pipe 23 need to extend upward at the upper end of the cleaning rod 1. The length of the cleaning rod 1 is not less than 3 meters;

[0042] A handle 11 is also provided at the upper end of the cleaning rod 1, and the axis of the cleaning rod 1 is perpendicular to that of the handle 11. The upper end opening of the cleaning rod 1 extends out at the top of the handle 11.

[0043] A plurality of blades 4 are provided at the lower end of the cleaning rod 1. The plurality of blades 4 are evenly arranged around the cleaning rod 1, and the outer end of each blade 4 is inclined downward. The cutting edge of the blade 4 extends below the cleaning rod 1; The lower end of the cleaning rod 1 is fixedly sleeved with a mounting block 41, and the lower end opening of the cleaning rod 1 extends out at the bottom of the mounting block 41;

[0044] The plurality of blades 4 are evenly installed on the mounting block 41. The mounting block 41 and the blade 4 can be detachably locked by threads. The blade 4 forms a downwardly inclined and curved structure, which has the same function and shape as the stirring blade of a mixer.

[0045] A plurality of positioning rods 3 are also provided on the cleaning rod 1.

The positioning rod 3 is a straight rod that can elastically expand and contract, and an auxiliary wheel 31 is also installed at the outer end of the positioning rod 3; the auxiliary wheel 31 is a universal wheel.

[0046] There are two positioning rods 3, and the two positioning rods 3 are symmetrically arranged on the cleaning rod 1, and the height difference between the positioning rod 3 and the lower end of the cleaning rod 1 is between 0.5 and 1 meter;

[0047] A fixing rod 32 is horizontally arranged at the inner end of the positioning rod 3. The positioning rod 3 is connected to the fixing rod 32 by a spring. The positioning rod 3 is slidably sleeved inside the fixing rod 32, and the fixing rod 32 is fixed on the cleaning rod 1.

[0048] The sewage tank 5 and the water purification tank 51 are water storage tanks, both of which can be portable water kettles, and can be water buckets of 50-100 liters. The sewage tank 5 and the water purification tank 51 are placed at fixed positions, or can move flexibly with the cleaning rod 1. They can be carried by a trolley and move with the construction. The sewage tank 5 and the water purification tank 51 are connected by a connecting pipe 52. A filter screen is arranged inside the connecting pipe 52; a sponge filter pad is also arranged inside the connecting pipe 52;

[0049] Both ends of the connecting pipe 52 are respectively communicated with the inner cavity bottom of the sewage tank 5 and the water purification tank 51, and the connecting pipe 52 is a straight pipe;

[0050] An injection port is also provided at the top of the water purification tank 51. The injection port is covered with a sealing plug that can be opened by a thread, and clean flushing water can be directly injected into the water purification tank 51 by opening the lid.

[0051] A drain port is also provided at the bottom of the sewage tank 5, and the drain port is tightly covered by a sealing plug. The sludge in the sewage tank 5 can be discharged through the drain port, or it can be blocked so that the sewage pumped out from the pipe pile can be reused repeatedly through the filter screen and sponge filter pad in the connecting pipe 51 to reduce the waste of water resources. Until the sewage viscosity is too high, the sludge in the sewage tank 5 can be discharged and collected to a specified place for unified treatment, which is more convenient for operation.

[0054] A switch 12 is also provided on the handle 11. There can be two switches 12. The water spray pump 2 and the water suction pump 21 are connected to the switch 12. The water spray pump 2 and the water suction pump 21 can be independently controlled by the switch 12 to start working, so as to suck mud and also perform high-pressure water spraying for dredging.

[0055] It should be noted that:

[0056] 1. In the current conventional method for cleaning the soil in pipe piles, the soil at the bottom of the pipe pile is usually dug outwards to achieve the purpose of soil cleaning. During actual construction, the operation is laborious, and the dug-out soil is generally silt, which will cause serious pollution around the pipe pile opening. The mud will also make it inconvenient for workers to walk and cause slipping when standing, all of which will bring great troubles to the construction. The current method for silt cleaning will inevitably cause the dug-out silt to flow down and scatter. This device changes this situation. It directly dilutes the silt inside the pipe pile and then sucks it out, stores it in the sewage tank 5 for subsequent treatment, and has basically no impact on the surrounding environment.

[0057] 2. For the currently dried and hard soil inside the pipe pile, it is necessary to inject water for soaking until the soil is infiltrated and softened, and then cut and broken, and then cleaned out. This device directly cuts through high-pressure water spraying. The sprayed water not only breaks the dried soil but also infiltrates the soil, finally forming muddy water, and then the muddy water is sucked out by the water suction pump 21, saving the cleaning work. Moreover, through the combined action of high-pressure water spraying and the blade 4, while spraying water and cutting, the soil is turned into muddy water, changing the method for cleaning the soil inside the pipe pile, making the cleaning simpler and more convenient.

[0058] 3. The currently commonly used cleaning device is to use a long rod to break the soil, inject water, and then use a long-handled spoon to dig out the soil. The long rod is very easy to hang on the pipe pile opening, and the pointed part and the spoon part are easy to hit the inner wall of the pipe pile, causing unnecessary damage. Not only is the tool easily damaged, but the pipe pile may also be damaged. Moreover, it is laborious to hold the long-handled tool. This device is equipped with a positioning rod 3 and auxiliary wheels 31, which can help position the cleaning rod 1. Even when holding the relatively long cleaning rod 1, it can be assisted by the positioning rod 3, making it more labor-saving and more convenient for rotating and cutting.

[0059] When this utility model is in use:

[0060] 1. First, fill the portable water purification tank 5 with water and connect it to the portable 48V power supply.

[0061] 2. Place the cleaning rod 1 at the pipe pile opening and vertically insert the cleaning rod 1 into the pile hole, so that the positioning rod 3 elastically supports on the vertical side wall of the pipe pile hole.

[0062] 3. Turn on the water spraying switch 12 and simultaneously rotate the handle 11. Through the combined action of the blade 4 and the high-pressure nozzle at the water outlet end of the water spraying pipe 22, soften and break the soil in the pile core.

[0063] 4. After rotating the cleaning rod 1 and spraying water for 30 seconds, turn on the water suction switch 12 to suck the softened soil into the temporary sewage tank 5.

[0064] 5. Suction water for 10 seconds.

[0065] 6. Repeat the operations of spraying water and rotating the blade 4 for cutting, and then suction water again. Continuously repeat this operation, and the water spraying and water suction duration can be appropriately extended until the design depth is reached and the operation stops.

[0066] During this period, the water in the sewage tank 5 will flow back to the water purification tank 51 through the connecting pipe 52 to achieve the purpose of recycling sewage.

[0067] Although the specific implementation manners of the present utility model have been described above, those skilled in the art of this technology should understand that the specific embodiments we described are illustrative rather than used to limit the scope of the present utility model. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present utility model should all be covered by the scope protected by the claims of the present utility model.
