Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation sediment cleaning, in particular to an instrument for efficiently cleaning the thickness of pile foundation sediment. Background Art

[0002] Pile foundation is a kind of foundation form with high bearing capacity, wide application range and long history. Pile foundation sediment mainly refers to the large amount of sediment that appears at the bottom of the pile foundation during the construction of the pile foundation. These sediments are formed by the agglomeration of some materials that cannot be evenly dispersed in the borehole due to poor concrete fluidity or other reasons during the drilling and cleaning process. The sediment is generally composed of cement slurry, sand, gravel, etc. Its shape and content will affect the quality and performance of the bored piles. Therefore, during the construction of bored piles, it is necessary to clean the sediment at the bottom of the hole to avoid excessive thickness of the sediment, create good conditions for pouring underwater concrete, make the depth measurement correct, and pouring smoothly, ensure the quality of concrete, and avoid major engineering quality accidents such as broken piles.

[0003] After searching, the existing methods of cleaning pile foundation sediment usually include the following:

[0004] 1. High-pressure water gun flushing: Use a high-pressure water gun to flush the bottom of the pile, and use the high-pressure water flow to flush the sediment out of the hole. This method is simple to operate and has a good cleaning effect, but you must pay attention to controlling the water pressure and flushing time to avoid damage to the pile body.

[0005] 2. Mud circulation cleaning: During the drilling process, the mud and sediment in the hole are discharged through the mud circulation system. This method can clean the sediment in real time, but attention should be paid to the performance and circulation speed of the mud to ensure the cleaning effect.

[0006] 3. Grab bucket: Use a special grab bucket to reach into the bottom of the hole to grab the sediment and lift it out of the hole. This method is suitable for situations where the sediment is large or concentrated, and the cleaning efficiency is high.

[0007] 4. Air compressor suction: Use the airflow generated by the air compressor to suck out the sediment at the bottom of the hole through the pipeline. This method is suitable for situations where the sediment is fine or the space at the bottom of the hole is small, but it is necessary to control the airflow speed and suction force to avoid damage to the hole wall.

[0008] However, no matter which of the above solutions is adopted, although it can realize the cleaning of pile foundation sediment, there are still some shortcomings in the actual cleaning:

[0009] 1. High-pressure water gun flushing: Although it can effectively flush the sediment at the bottom of the pile, it is necessary to ensure that the angle and pressure of the water gun are properly controlled during operation, otherwise it may cause scouring damage to the pile body or hole wall. In addition, for larger particles of sediment, it may be difficult to completely remove them by simply relying on water gun flushing.

[0010] 2. Mud circulation cleaning: This method can clean the sediment in real time, but the performance of the mud and the circulation speed have a great influence on the cleaning effect. If the mud is too thick or the circulation speed is insufficient, the sediment may not be effectively discharged. At the same time, the treatment and discharge of the mud are also environmental issues that need to be considered.

[0011] 3. Grab bucket grabbing: The method of grabbing sediment is more efficient, but it is necessary to ensure that the grab bucket can accurately grab the sediment without damaging the pile body or hole wall. In addition, the grab bucket may not be able to effectively grab smaller or finer sediment particles.

[0012] 4. Air compressor suction: Air compressor suction is suitable for situations where the sediment is fine or the space at the bottom of the hole is small, but the air flow speed and suction force need to be controlled during operation to avoid damage to the hole wall. At the same time, the operation and maintenance of air compressor equipment may also increase costs.

[0013] Therefore, it is necessary to design an efficient cleaning instrument for pile foundation sediment thickness to solve the above-mentioned problems. Utility Model Content

[0039] A highly efficient cleaning instrument for pile foundation sediment thickness comprises an upper sediment discharge pipe 1 located at the top, the bottom of the upper sediment discharge pipe 1 is connected to a lower sediment discharge pipe 2, the bottom of the lower sediment discharge pipe 2 is connected to an inner collecting pipe 3, the inner collecting pipe 3 is also provided with a sediment thickness detector or a thickness detection sensor for detecting the sediment thickness, an aggregation hood 4 is installed at the bottom of the lower sediment discharge pipe 2 and the periphery of the connecting end of the inner collecting pipe 3, and a plurality of fixed frames 5 and a foldable frame 6 for fixing the aggregation hood 4 are also respectively provided at the periphery of the lower sediment discharge pipe 2.

[0040] Specifically, the overall diameters of the upper slag discharge pipe 1 and the lower slag discharge pipe 2 are consistent, and the upper slag discharge pipe 1 and the lower slag discharge pipe 2 are fixedly connected by multiple bolts through a flange 8; the outer peripheries of the upper slag discharge pipe 1 and the lower slag discharge pipe 2 are fixedly provided with multiple connecting ear plates 9, and every two connecting ear plates 9 are connected by threaded rods 10 and fixing nuts 11; the two sides of the fixed frame 5 and the outer side of the lower slag discharge pipe 2 are fixedly connected by fixed connecting pieces 13, and one side of the foldable frame 6 is rotatably connected to the lower position of the outer side of the lower slag discharge pipe 2 through a hinged connecting piece 12; the gathering hood 4 is a truncated cone structure as a whole, which is designed to be small at the top and large at the bottom, and the gathering hood 4 is made of flexible composite materials, and the sediment is adsorbed into the slag discharge pipe through the inner collecting pipe 3 below, and is uniformly collected in the collection device or collection area at the rear, and at the same time, through the action of the gathering hood 4, the sediment is gathered together, which is convenient for subsequent cleaning, and can effectively control the diffusion and pollution of the sediment, reducing the negative impact on the environment.

[0041] The upper slag discharge pipe 1, the lower slag discharge pipe 2 and the inner collecting pipe 3 are made of wear-resistant alloy steel to achieve corrosion resistance and are suitable for long-term use in this environment.

[0042] Specifically, an air inlet pipe 7 connected to the interior of the instrument is fixedly provided on the outer side of the upper slag discharge pipe 1, and the air inlet pipe 7 is also connected to an external air inlet device, so as to provide the device with necessary airflow or gas pressure, so as to more effectively gather and remove the sediment; specifically, when the air inlet pipe 7 is working, it can generate an airflow or provide a certain gas pressure, which helps to attract the sediment near the pipe mouth into the gathering device.
