Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation engineering construction, and more specifically, to a pile foundation acoustic detection pipe cleaning device. Background Art

[0002] After the pile foundation construction is completed, the integrity of the pile foundation is generally detected by ultrasonic testing. The detection is carried out by installing the acoustic detection tube in advance while the steel bars are installed. When the acoustic detection tube is tested, it is filled with clean water. However, when the detection is carried out, during the pile foundation construction process or due to various other reasons, the internal rust of the acoustic detection tube is serious, the water quality is turbid, foreign matter and debris fall into the acoustic detection tube, or the acoustic detection tube is blocked. It is necessary to clean and dredge in time, otherwise it will cause the detection to be unable to be carried out or the detection result is distorted, resulting in misjudgment. How to clean the acoustic detection tube quickly and conveniently is a difficult problem that needs to be solved urgently in pile foundation construction. The method usually adopted is to connect the steel bars one by one, and then put them into the detection tube, stir the debris or blockage for cleaning, and then inject clean water to circulate and remove the cleaned debris or blockage, etc., which takes a long time and cannot better handle and clean the inner wall of the acoustic detection tube. Another way is to use an ultrasonic vibrator to vibrate the debris or blockage to achieve the cleaning of the acoustic detection tube, but it is also necessary to install an ultrasonic vibrator, which is complex in structure, high in cost, and inconvenient.

[0018] In order to better understand the purpose, structure and function of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement it according to the description.

[0019] It should be noted that, in the description of the present invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] like Figure 1 As shown, the utility model provides a cleaning device for a pile foundation acoustic detection pipe 1, comprising a cleaning pipe 2, a drill bit 3 fixedly connected to the bottom of the cleaning pipe 2, and a cleaning unit arranged at the lower part of the cleaning pipe 2, the drill bit 3 is used to break the blockage inside the acoustic detection pipe 1, and a plurality of groups of cleaning units are vertically spaced at intervals at the lower part of the cleaning pipe 2, each group of cleaning units includes a plurality of cleaning brushes 4, which are evenly spaced along the circumference of the cleaning pipe 2, and the plurality of cleaning brushes 4 included in the plurality of groups of cleaning units are staggered up and down, and the cleaning brush 4 includes a connecting plate 5 fixedly connected to the cleaning pipe 2 and a brush head 6 arranged at the end of the connecting plate 5, and the brush head 6 is arranged close to the inner wall of the cleaning pipe 2.

[0021] The cleaning pipe 2 extends vertically downward into the acoustic detection pipe 1, and the multiple cleaning brushes 4 corresponding to the multiple cleaning units at the bottom are used to rub and remove the debris, rust, etc. on the inner wall of the acoustic detection pipe 1. The multiple cleaning brushes 4 corresponding to the multiple cleaning units can basically cover a plane of the inner wall of the acoustic detection pipe 1, and the inner wall of the acoustic detection pipe 1 can also be cleaned more comprehensively and deeply by rotating or moving the cleaning pipe 2 up and down. The brush head 6 is set close to the inner wall of the acoustic detection pipe 1. The brush head 6 is a relatively coarse and hard bristle to generate a greater friction with the inner wall of the acoustic detection pipe 1, and the cleaning effect is better. When the cleaning pipe 2 is lowered to encounter an obstruction, the cleaning pipe 2 is driven to rotate, thereby driving the drill bit 3 to rotate, so as to break the obstruction, and the cleaning pipe 2 can be driven to rotate by a drilling rig or other equipment. The drill bit 3 can cover at least two-thirds of the plane range of the acoustic detection pipe 1. The drill bit 3 and the cleaning unit are used to completely and fully clean the inner wall of the acoustic detection tube 1, internal blockages and other debris to make them suspended, and then water is injected into the acoustic detection tube 1 to circulate the water to remove the debris or blockages cleaned out of the acoustic detection tube 1.

[0022] In another embodiment, the connecting plate 5 is tilted upward and the angle between it and the cleaning pipe 2 is greater than 45 degrees, the brush head 6 is vertically arranged toward the inner wall of the cleaning pipe 2, and the connecting plate 5 is a mesh structure and the mesh size is set to allow water to pass freely. The connecting plate 5 is set to a mesh structure, which is equivalent to a filter form. At the same time, the connecting plate 5 is set to be tilted upward, so that larger debris can fall onto the connecting plate 5, avoiding sinking to the bottom of the acoustic detection pipe 1 and being inconvenient to circulate out of the pipe through the water. The cleaning pipe 2 can be moved up and down to achieve stirring, so that the debris can fall smoothly onto the connecting plate 5, or it can be stirred by passing high-pressure water to facilitate the debris to fall smoothly onto the connecting plate 5. High-pressure water can further assist in the cleaning of the inside of the acoustic detection pipe 1.

[0023] In another embodiment, a pair of baffles 7 are provided on opposite sides of the outer periphery of the connecting plate 5, which are also mesh structures and the mesh size is set to allow water to pass freely, and a holding space is formed between the pair of baffles 7 and the connecting plate 5. The setting of the mesh structure baffles 7 forms a holding space to prevent the sundries that fall onto the connecting plate 5 from escaping again, and the baffles 7 can be set to be connected to the cleaning pipe 2, so that the holding space is in a basically closed state except for the top.

[0024] In another embodiment, the cleaning pipe 2 is composed of multiple pipe units assembled by threads, and the drill bit 3 is also connected to the cleaning pipe 2 by thread disassembly, which is convenient for sequential installation and removal. When cleaning is completed, high-pressure water-assisted treatment is performed or the debris or blockage cleaned out of the acoustic detection pipe 1 is taken out by circulating clean water, the lowest pipe unit and the drill bit 3 are removed, and the cleaning pipe 2 acts as a water pipe. After cleaning is completed, it is more convenient to remove the pipe units in sequence or to lower and install the pipe units in sequence before cleaning.

[0025] In another embodiment, multiple groups of cleaning units are located on a pipe unit at the bottom of the cleaning pipe 2. After cleaning is completed, the drill bit 3 and the bottom pipe unit are removed to facilitate water circulation.

[0026] It can be understood that the present invention is described by some embodiments, and those skilled in the art know that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present invention. Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation mode. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, other modifications can be easily realized. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to specific details and the illustrations shown and described here.
