Description

Technical Field

[0001] This utility model belongs to the field of construction pile foundation technology, specifically, it relates to an early warning device for pile foundation tilt detection. Background Technology

[0002] In various pile foundation projects, such as buildings, bridges, docks, and ports, pile foundation tilt detection and early warning devices can be used for monitoring and early warning. A pile foundation tilt detection and early warning device is a device used to monitor and warn of the tilting state of pile foundations. It can help engineering projects to discover and solve pile foundation tilting problems in a timely manner and issue early warning signals to prevent potential safety risks and engineering quality problems.

[0003] A document with publication number CN222559745U discloses a pile foundation tilt detection and early warning device, including a pile foundation body and a connecting frame. The connecting frame is provided on the pile foundation body, and a fixed plate is fixedly connected to the connecting frame. The alarm is fixedly connected to the connecting frame. This application is equipped with a locking block; when the connecting frame is spliced, the two connecting frames can be sleeved on the pile foundation body, and the two connecting frames are in close contact. The pull rod on the locking block can be pulled, and when the pull rod moves the limiting plate, the limiting plate can compress the first spring. Then, the locking block can be slidably locked into the fixed plate on the two connecting frames. After locking, the pull rod is released, and the locking rod on the pull rod can lock into the fixed plate for splicing, preventing the two connecting frames from falling off. Moreover, the installation and disassembly are relatively convenient, only requiring the locking rod to lock the locking block for splicing, avoiding the waste of time in disassembly and installation.

[0004] The above-mentioned device only improves the installation direction in the tilt detection of pile foundations. However, in actual use, the tilt angle of the pile foundation is uncertain. The detection effect is limited by a small number of detection ports, and the detection position is fixed, which is not applicable. In actual use, the tilt risk needs to be determined according to the site environment. If the tilt risk is irregularly distributed, the detection effect of the existing device will be affected.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0026] Please see Figure 1-5A pile foundation tilt detection early warning device includes a detection component for detecting pile foundation tilt. The detection component includes a main body 1, a toothed groove 11, a frame 3, a locking block 34, and an abutment end 43. The main body 1 is composed of two identical hoop bodies. The toothed groove 11 is fixedly connected to the main body 1. The frame 3 slides at corresponding positions to the main body 1. The locking block 34 is elastically connected to the corresponding frame 3, and there is intermittent locking between the locking block 34 and the toothed groove 11. The abutment end 43 is symmetrically arranged on the corresponding frame 3 and contacts the wall surface of the pile foundation. After the pile foundation construction, this device is installed in a suitable area at the bottom of the pile foundation. After assessing the tilt risk around the pile foundation, the locking block 34 on the frame 3 is lifted. After the locking block 34 is separated from the tooth groove 11, the positions of multiple frames 3 are moved to the high-risk area. The locking block 34 is then released and locked again with the tooth groove 11. The elastically set abutment end 43 is tightly attached to the wall of the pile foundation to quickly detect the tilt of the pile foundation. After the tilt is detected, an electrical signal is transmitted to remind the maintenance personnel.

[0027] The method for assessing tilt risk needs to be combined with analysis based on the actual construction environment. After exploring the loose and soft areas of the soil layer in the foundation, the direction of that area is determined to be a high-risk area, and that area is the focus of the inspection.

[0028] The frame 3 is slidably connected to a slide rod 32, and the corresponding slide rod 32 is fixedly connected to a locking block 34. Each slide rod 32 is fitted with a first spring 33, and the end of each first spring 33 is fixedly connected to the corresponding frame 3 and slide rod 32. The locking block 34 is slidably connected to the corresponding frame 3. When the slide rod 32 is pulled upward by hand, the slide rod 32 stretches the first spring 33, and the first spring 33 deforms and applies the deformation force to the slide rod 32. After the locking block 34 separates from the tooth groove 11, it pushes the frame 3 to move, changing the position of the frame 3 and changing the detection position. This facilitates key detection of high-risk areas and improves the detection effect. After the position is changed, the force on the slide rod 32 is released. Under the action of the deformation force of the first spring 33, the slide rod 32 is pushed downward. The slide rod 32 drives the locking block 34 to lock with the tooth groove 11 again, thereby restricting the position of the frame 3.

[0029] Each frame 3 is fixedly connected to an installation plate 4, and each abutment end 43 is symmetrically arranged on the corresponding installation plate 4. Each abutment end 43 is symmetrically provided with a movable rod 41. Each movable rod 41 is fixedly connected to the same abutment end 43. Each movable rod 41 is fitted with a second spring 42. The end of each second spring 42 is fixedly connected to the corresponding installation plate 4 and abutment end 43 respectively. Each movable rod 41 is slidably connected to the installation plate 4. After the position of the frame 3 is adjusted, the abutment end 43 is tightly fitted to the wall of the pile foundation. The abutment end 43 is pushed by the pile foundation. The abutment end 43 drives the movable rod 41 and compresses the second spring 42. The second spring 42 deforms and applies the deformation force to the abutment end 43, making the fit between the abutment end 43 and the pile foundation tighter.

[0030] A displacement detector is installed in the sliding connection position between the movable rod 41 and the mounting plate 4 to detect the sliding distance of the movable rod 41. During installation, the displacement detector is turned off, and after installation, the displacement detector is turned on to detect the displacement of the movable rod 41 in real time and to issue an alarm when displacement occurs, thereby visually detecting the tilt of the pile foundation.

[0031] It is worth noting that the displacement detector is configured to receive a transmitted signal output from the transmitted signal output unit by a receiving electrode arranged in the detection head, so as to detect the displacement between the detection head and the scale based on the received signal. The transmitted signal is sent from the transmitting electrode arranged in the detection head to the receiving electrode through a coupling electrode arranged in the scale. The phase adjustment unit generates a signal whose phase is adjusted from the transmitted signal output from the transmitted signal output unit. The amplitude adjustment unit adjusts the amplitude of the signal whose phase is adjusted by the phase adjustment unit to generate a crosstalk correction signal. The demodulation unit samples the signal generated by synthesizing the crosstalk correction signal and the received signal and demodulates the sampled signal. The displacement detector has been fully disclosed in the document displacement detector with publication number CN108387167B, and will not be described again here.

[0032] Each hoop is fixedly connected to a connecting block 13 at its end. The connecting blocks 13 are connected to each other by fasteners, including but not limited to bolts. The inner wall and bottom of the main body 1 are provided with sliding grooves 12. Each frame 3 is fixedly connected to a corresponding wall surface with a slider 31. The corresponding slider 31 is slidably connected to the sliding groove 12. Each hoop is fixedly connected to a limit block 14 at its end. After the main body 1 is assembled from both sides of the pile foundation, the main body 1 is connected by the connecting blocks 13 and fasteners. When the frame 3 is damaged or needs to be disassembled, the main body 1 is separated. The locking block 34 is manually pulled upward to separate the locking block 34 from the tooth groove 11 and to make the locking block 34 exceed the height of the limit block 14. The frame 3 slides in the screw rod 21 with the help of the slider 31 and is removed from the main body 1, realizing the quick disassembly of this device for the maintenance and storage of internal components.

[0033] Multiple movable blocks 2 are rotatably connected to the wall of the main body 1. Each movable block 2 is connected to a lead screw 21 by a thread in the middle. When the lead screw 21 is rotated, it contacts the working surface and provides auxiliary support for the movable block 2 and the main body 1, so that the main body 1 and the wall surface being impacted are in a corresponding parallel state.

[0034] Working principle: After pile foundation construction, this device is installed in a suitable area at the bottom of the pile foundation. After assessing the tilt risk around the pile foundation, the locking block 34 on the frame 3 is lifted. After the locking block 34 separates from the toothed groove 11, the positions of multiple frames 3 are moved to the high-risk area. The locking block 34 is then released and locked back into place with the toothed groove 11. The elastically set abutment end 43 fits tightly against the wall of the pile foundation, quickly detecting the tilt degree of the pile foundation. After detecting tilt, an electrical signal is transmitted to remind maintenance personnel. The tilt risk assessment method needs to be combined with analysis based on the actual construction environment, considering areas with loose or soft soil layers within the foundation. After the area is explored, it is determined to be a high-risk area, and this area is the focus of the inspection. The sliding rod 32 is pulled upwards manually, stretching the first spring 33. The first spring 33 deforms, and the force of this deformation is applied to the sliding rod 32. After the locking block 34 separates from the toothed groove 11, it pushes the frame 3 to move, changing the position of the frame 3 and thus the inspection position. This facilitates focused inspection of the high-risk area, improving the inspection effect. After the position is changed, the force on the sliding rod 32 is released. Under the deformation force of the first spring 33, the sliding rod 32 is pushed downwards, causing the locking block 34 to re-engage with the toothed groove 11, thus repositioning the frame 3. After the position of the frame 3 is adjusted, the abutment end 43 is tightly fitted against the wall of the pile foundation. The abutment end 43 is pushed by the pile foundation, which drives the movable rod 41 and compresses the second spring 42. The second spring 42 deforms and applies the deformation force to the abutment end 43, making the fit between the abutment end 43 and the pile foundation even tighter. A displacement detector is installed in the sliding connection position between the movable rod 41 and the mounting plate 4 to detect the sliding distance of the movable rod 41. During installation, the displacement detector is turned off, and after installation, it is turned on to detect the displacement of the movable rod 41 in real time and to issue an alarm if displacement occurs. The tilt of the pile foundation is directly detected. After the main body 1 is assembled from both sides of the pile foundation, the main body 1 is connected by the connecting block 13 and fasteners. When the frame 3 is damaged or needs to be disassembled, the main body 1 is separated. The locking block 34 is pulled upward manually to separate the locking block 34 from the tooth groove 11 and make the locking block 34 exceed the height of the limit block 14. The frame 3 slides in the screw 21 with the help of the slider 31 and is removed from the main body 1, realizing the quick disassembly of the device for the maintenance and storage of internal components. After the screw 21 is rotated and contacts the working surface, it provides auxiliary support for the movable block 2 and the main body 1, forming a corresponding parallel state between the main body 1 and the impacted wall.
