Description

Technical Field

[0001] This utility model relates to a protective device for a dynamic detection system for the diameter of loose-body piles. Background Technology

[0002] As land reclamation projects have expanded from coastal and near-shore areas to offshore and deep-water areas, the depth of foundation reinforcement has also increased. Crushed stone piles or compacted sand piles are common foundation reinforcement methods. They not only have a certain load-bearing capacity in their framework, but also a certain drainage and consolidation capacity, which can promote drainage and consolidation of the surrounding soil, thereby improving the bearing capacity of the foundation.

[0003] However, as the reinforcement depth increases, the construction quality requirements for the pile diameter during the construction of crushed stone piles or sand piles also become more stringent. Currently, the main methods for quality inspection of crushed stone piles are sonic logging, core drilling, or dynamic penetration testing. The pile diameter is primarily estimated indirectly based on the amount of material used, which can lead to significant errors. Sonic logging uses a low frequency, resulting in poor resolution of the target object. Furthermore, the discontinuous nature of the single-point detection area can easily introduce large errors. Core drilling and dynamic penetration testing can only detect the compaction of the pile and cannot provide direct data on the pile diameter.

[0004] Existing methods use ultrasonic detection to directly monitor or detect the diameter of loose piles such as crushed stone piles and sand piles. Especially for crushed stone piles with a depth of more than 20 meters, ultrasonic detection is not affected by groundwater and has high resolution, making it suitable for detecting the diameter of loose piles. However, existing methods lack adequate protection for ultrasonic probes, which can easily lead to damage during detection and cause serious economic losses. Therefore, to address these issues, a protective device for a dynamic detection system for the diameter of loose piles is proposed. Utility Model Content

[0005] The purpose of this utility model is to overcome the existing defects and provide a protective device for a dynamic detection system of the diameter of loose piles, which effectively protects the detection equipment and avoids damage.

[0006] The technical solution to achieve the above objective is: a protective device for a dynamic detection system for the diameter of loose-body piles, including a probe cone and a signal line protection assembly;

[0007] The probe cone is connected to the lower end face of the crushed stone pile pipe, the signal line protection assembly is connected to the side wall of the crushed stone pile pipe, and the transmission line inside the probe cone passes through the signal line protection assembly to the upper part of the crushed stone pile pipe.

[0008] The probe cone includes a cylindrical body and a protective cone. The protective cone is connected to the lower end of the cylindrical body, and the upper end of the cylindrical body is connected to the crushed stone pile pipe. The transducer is disposed inside the cylindrical body and is connected to the output end of the servo motor. The transducer is connected to a transmission line.

[0009] Preferably, a protective cover is connected to the upper end of the cylindrical body, a shock-absorbing spring is connected to the lower end of the protective cover, and the lower end of the shock-absorbing spring is connected to the servo motor.

[0010] Preferably, the side wall of the cylindrical body is provided with a sound wave transmission window.

[0011] Preferably, the signal line protection assembly includes a protective tube connected to the side wall of the gravel pile pipe. The gravel pile pipe has a hole, and the transmission line passes through the hole and the protective tube. Multiple wire connectors are connected at equal intervals inside the protective tube for connecting the transmission line.

[0012] Preferably, the protective tube is filled with foamed shock-absorbing adhesive.

[0013] Preferably, the protective pipe is connected to the crushed stone pile pipe by multiple channel steels arranged at equal intervals.

[0014] The beneficial effects of this utility model are: the protective device of this dynamic detection system for the diameter of granular piles enables the transducer to operate under conditions of strong vibration, strong friction, and high pressure, achieving real-time detection of the granular pile diameter through 360-degree omnidirectional rotation of the transducer; effectively protecting the detection equipment and preventing damage. The successful application of this structure will change the shortcomings in the field of granular pile construction, where the construction process cannot be detected and there are no direct means of detecting construction quality.

In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figure 1-3 As shown, a protective device for a dynamic detection system for the diameter of a loose-grain pile includes a probe cone 1 and a signal line protection assembly. The probe cone 1 is connected to the lower end face of a crushed stone pile pipe 2, and the signal line protection assembly is connected to the side wall of the crushed stone pile pipe 2. The transmission line 3 inside the probe cone 1 passes through the signal line protection assembly to the upper part of the crushed stone pile pipe 2. The probe cone 1 includes a cylindrical body 11 and a protective cone 12. The protective cone 12 facilitates soil breaking and is connected to the lower end of the cylindrical body 11. The upper end of the cylindrical body 11 is connected to the crushed stone pile pipe 2. A transducer 4 is disposed inside the cylindrical body 11 and is connected to the output end of a servo motor 5. The transducer 4 is connected to the transmission line 3. A protective cover 13 is connected to the upper end of the cylindrical body 11, and a shock-absorbing spring 14 is connected to the lower end face of the protective cover 13. The lower end of the shock-absorbing spring 14 is connected to the servo motor 5. A sound wave transmission window 15 is provided on the side wall of the cylindrical body 11.

[0022] Specifically, the cylindrical body 11 is a high-strength stainless steel protective box, which houses the core ultrasonic detection device, transducer 4 (along with the servo motor). The front end of the protective box is designed with a 60-degree acute angle to enhance its penetration ability in the soil. After the transmission line 3 and the cable pass through the protective box, they pass through the hollow small steel pipe in sequence, and the steel pipe is welded to the outside of the crushed stone pile pipe section by section to protect the cable.

[0023] Specifically, the servo motor 5 can drive the transducer 4 to rotate 360 ​​degrees, and can transmit and receive ultrasonic signals from the center of the crushed stone pile from the inside out. When the ultrasonic signal encounters the pile-soil reflection interface, the changes in the received ultrasonic signal can be analyzed to determine the reflection position and then the distance of the reflection interface can be obtained, thus realizing the detection of the pile diameter.

[0024] Specifically, the above structure enables the transducer to operate under conditions of strong vibration, strong friction, and high pressure, and allows for real-time detection of the diameter of the granular pile through 360-degree omnidirectional rotation of the transducer. The successful application of this structure will change the shortcomings in the field of granular pile construction, where the construction process cannot be detected and there are no direct means of detecting construction quality.

[0025] Specifically, the signal line protection assembly includes a protective tube 6, which is connected to the side wall of the gravel pile pipe 2. A hole 7 is formed inside the gravel pile pipe 2, through which the transmission line 3 passes. Multiple wire connectors 8 are connected at equal intervals inside the protective tube 6 for connecting the transmission line 3. The inside of the protective tube 6 is filled with foamed shock-absorbing material. The protective tube 6 is connected to the gravel pile pipe 2 via multiple equally spaced channel steels 9.
