Description

Technical Field

[0001] This utility model relates to the field of civil engineering construction technology, and in particular to a device for pinpointing and detecting pile foundation construction holes. Background Technology

[0002] As a crucial form of deep foundation in civil engineering (consisting of piles and pile caps forming a load-bearing system), the quality of pile foundation drilling directly impacts the load-bearing capacity and safety factor of the building structure. After pile foundation drilling is completed, precise point-to-point testing is essential to quantitatively assess core parameters such as borehole diameter, drilling depth, and verticality deviation, ensuring that all indicators strictly adhere to design specifications. This effectively avoids structural safety hazards caused by insufficient pile foundation bearing capacity due to excessive borehole diameter errors or loose soil around the borehole.

[0003] Traditional pile foundation borehole point detection devices are prone to instability and shaking during pile foundation testing, resulting in insufficient actual bearing area and potential tilting. This makes it impossible to accurately measure the diameter, depth, or sediment thickness of the pile hole, and may even lead to settlement or breakage. The detection head, exposed to the elements for extended periods, is prone to damage and requires replacement. The cumbersome replacement of traditional detection heads can affect the progress of all subsequent procedures, causing delays in the construction period. Therefore, a pile foundation borehole point detection device is proposed to solve the above problems. Utility Model Content

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when it is necessary to perform fixed-point testing of the pile foundation construction hole, the rotating shaft is rotated so that the pin can be inserted into the first insertion hole. At this time, the bottom plate is in contact with the ground, which increases the contact area between the entire pile foundation and the ground. When the bottom plate is subjected to external force, the sliding plate slides in the outer shell and the first spring deforms, reducing the shaking of the equipment and making the pile foundation more stable, thereby increasing the bearing area of ​​the pile foundation and making it more stable.

At this time, the pull ring is released, and the pull rod rebounds due to the action of the second spring, thereby fixing the test head and solving the problem of difficult disassembly and replacement.

The base plate 11 is slidably connected to the inside of the housing 8. One end of the first spring 9 abuts against the inner top wall of the housing 8. The other end of the first spring 9 is fixedly connected to the top of the slide plate 10. The support leg 7 is rotatably connected to the inside of the fixed block 5, and the pin 4 is slidably connected to the inside of the first insertion hole 24.

[0034] The bearing plate 1 is used to support and fix the entire pile foundation device, the support plate 2 is used to support and connect various parts, the cover plate 3 is used to fix the support plate 2 and the fixing plate 15, the fixing plate 15 is used to install the brush 16, the brush 16 is used to clean the rope 14 to prevent mud from affecting the accuracy of the next measurement, the motor 12 drives the rotating drum 13 to rotate, the rotating drum 13 is used to fix and wind up and stretch the rope 14, the rope 14 drives the fixing column 17 to rise and fall, the fixing column 17 is used to support and fix various parts, and the connecting column 18 is used to install the detection head 19 in the fixing column 17;

[0035] The fixing block 5 is used to fix and support the various parts, providing a place for the rotation shaft 6 and the support leg 7 to move. The pin 4 adjusts the rotation of the shaft 6 by connecting the first insertion hole 24 and the two second insertion holes 25. When the base plate 11 is in contact with the ground, the pin 4 is inserted into the first insertion hole 24 for fixing. When the support leg 7 and the entire support mechanism are stored, the pin 4 is inserted into the second insertion hole 25 for fixing. The support leg 7 is used to fix the outer shell 8. The outer shell 8 is used to fix the first spring 9 and the sliding plate 10 and provide a sliding place for the sliding plate 10. The first spring 9 is used to provide a buffer force to the base plate 11 when it is under force, and plays a buffering role for the entire pile foundation. The sliding plate 10 is used to fix the base plate 11 and the first spring 9.

[0036] Reference Figure 1 and Figure 4 The fixing mechanism includes two hollow columns 20, both of which are symmetrically distributed and fixedly connected to the outside of a fixing column 17. A pull rod 21 is slidably connected inside each hollow column 20. A second spring 23 is sleeved on the outside of the pull rod 21. A washer 22 is fixedly connected to the outside of the pull rod 21.

The outside of the washer 22 is slidably connected inside the hollow column 20.

[0037] Hollow column 20 is used to fix various parts and provide a space for movement for pull rod 21 and washer 22. Pull rod 21 is used to fix connecting column 18 so that detection head 19 is firmly installed on fixed column 17. Second spring 23 makes pull rod 21 firmly fixed to connecting column 18 when no external force is applied. Washer 22 is used to fix spring and at the same time transmit the elastic force of second spring 23 to pull rod 21.

[0038] Working principle: When fixed-point testing of pile foundation construction holes is required, the pin 4 is pulled out from the second insertion hole 25, and the rotating shaft 6 is rotated. The support leg 7 rotates accordingly until the pin 4 can be inserted into the first insertion hole 24. When the pin 4 is inserted into the first insertion hole 24, the base plate 11 is in contact with the ground and will be squeezed by the ground. At this time, the base plate 11 exerts an upward force on the sliding plate 10. The first spring 9 and the sliding plate 10 slide in the outer shell 8, thereby reducing the shaking of the equipment and making the pile foundation more stable. This increases the bearing area of ​​the pile foundation and makes it more stable, increasing the contact area between the entire pile foundation and the ground. At this time, the motor 12 is started, and the rotating drum 13 rotates, driving the rope 14 to descend so that the detection head 19 can inspect the pile foundation construction hole. When the test is completed, the motor 12 is restarted, and the drum 13 rotates to wind up the rope 14. At the same time, the brush 16 cleans the rope 14 to prevent mud from affecting the accuracy of the next measurement. After the rope 14 has retracted, when the pile foundation test head 19 needs maintenance or replacement, pull the pull ring to pull the pull rod 21 out of the connecting column 18. At this time, the test head 19 can be taken out from the fixed column 17. After maintenance, the connecting column 18 on the test head 19 is reinserted into the fixed column 17. At this time, the pull ring is released, and the pull rod 21 rebounds due to the action of the second spring 23, so that the pull rod 21 is inserted into the connecting column 18 to fix the test head 19, thus solving the problem of difficult disassembly and replacement of the pile foundation test head 19.
