Description

Technical Field

[0001] This utility model relates to the field of bored pile technology, specifically to a closed drainage structure for negative pressure vacuum pile breaking. Background Technology

[0002] The main reason for breaking the pile head is to ensure the strength of the pile body concrete. During the concrete pouring process, due to the rise of air bubbles or pores inside the concrete to the top of the pile, a certain range of the pile top is filled with laitance or a mixture of mud and mortar. These substances have low strength. In order to ensure the strength of the pile body, it is necessary to remove the upper part of the false pile.

[0003] Traditional pile head removal processes require pile head removal to be carried out after the pile foundation grouting is completed and the foundation pit is excavated. Common methods for removing pile heads include manual removal and mechanical removal. Traditional processes have disadvantages such as high labor intensity, high occupational health hazards, high safety risks, high construction costs, slow process changeover, and heavy environmental pollution.

[0004] Therefore, it is particularly important to design a closed drainage structure for negative pressure vacuum pile breaking to overcome the above-mentioned technical defects and improve overall practicality. Utility Model Content

The top of the casing 1 is equipped with a hole protection net to protect the hole.

[0026] In this embodiment, please refer to Figure 2 One end of the outer side of the robotic arm 9 is fixed with a suspended bracket 901. A water pipe 902 is rotatably connected inside the suspended bracket 901. A rotary motor 903 is installed on the left side of the suspended bracket 901. The water pipe 902 passes through one end of the outer side of the suspended bracket 901 and the output end of the rotary motor 903, and is fitted with meshing gears 904. High-pressure nozzles 905 are evenly distributed on the outside of the water pipe 902.

[0027] The top of water pipe 902 is connected to an inlet connector for connecting to an external water source pipe.

[0028] In this embodiment, please refer to Figure 3 A fixing ring 801 is fitted to the bottom of the outer side of the air intake pipe 8. The bottom of the fixing ring 801 is connected to a spring group 803 through multiple evenly distributed supports 802. A vibrating ring 804 is installed below the multiple supports 802 at the bottom.

[0030] The workflow of this utility model: The vacuum material extraction method for pile head removal in bored cast-in-place piles is a "soft excavation" construction process. After concrete pouring, before the initial setting state, a vacuum pile breaker 6 is used to remove the pile head. The principle of this method is to use a vacuum negative pressure pump 4 to create negative pressure, and then use the negative pressure to create an airflow through the suction pipe 8, entraining concrete and slurry into the storage cylinder 2. If the concrete is in a large, sticky state and difficult to extract, a high-pressure nozzle 905 sprays high-pressure water to break up and decompose the concrete. A rotating motor 806 drives two sets of gears 90... 4. Engagement allows the water pipe 902 to change its spray angle, breaking down and decomposing the material to increase its suspension and flow characteristics. Simultaneously, the vibrating motor 806, in conjunction with the spring assembly 803, can cause the vibrating head 805 to break up large pieces of concrete so that they can be sucked into the suction pipe 8. After the cast-in-place pile is poured, the excess concrete and mud at the top of the pile are promptly removed. The material recovered inside the storage cylinder 2 is processed by the sand and gravel separator 3 for secondary use, which can eliminate many common quality defects and solve problems such as the difficulty of lifting the pile head and the environmental pollution caused by mud under restricted construction conditions.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
