Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation verticality detection, in particular to a pile foundation verticality detection instrument. Background Art

[0002] Pile foundation is an important basic structure of a building, and its verticality has a significant impact on the safety and stability of the building. With the increase in high-rise buildings and large-scale infrastructure, pile foundation verticality detection has become an important part of construction quality control.

[0003] Substandard verticality of the pile foundation may cause problems such as building tilt and settlement, seriously affecting the safety and service life of the building. Therefore, in order to promptly detect and correct construction errors in the verticality of the pile foundation, it is necessary to measure it using a pile foundation verticality detection instrument, so that pile foundation verticality problems can be detected in time and corresponding measures can be taken, thereby avoiding potential safety hazards and reducing the possibility of construction accidents.

[0004] However, in the process of measuring the verticality of pile foundation holes, most of the existing pile foundation verticality detection instruments place the instrument on the buried casing in the edge of the pile foundation hole for measurement. It is inconvenient to adjust the corresponding length according to the height and size of the casing, resulting in the inability to accurately measure the verticality of the pile foundation, making it impossible to determine whether the pile foundation hole meets the design requirements, which leads to cumbersome operation and poor applicability. At the same time, in the process of pile foundation measurement and acceptance, the existing pile foundation verticality detection instruments often do not have a vibration damping and buffering device, and this instability is easily affected by external factors such as collision and wind, so that the vibration generated by the surrounding construction during the measurement and acceptance will lead to defects such as low measurement accuracy, thereby affecting the judgment of the acceptance parameters.

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example 1

[0028] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a pile foundation verticality detection instrument, including a box body 1, a vertical first telescopic rod 2 is installed at the center of the upper end of the box body 1, and a vertical second telescopic rod 3 is installed at the center of the upper end of the vertical first telescopic rod 2, a locking collar 4 is provided on the outer side wall of the upper end of the vertical second telescopic rod 3, and a fixing bolt 5 is installed through the center of the outer side wall of one end of the locking collar 4, and clamping nuts 6 are symmetrically installed at both ends of the outer side wall of the fixing bolt 5, and anchor bolts 7 are installed around and evenly spaced around the outer side wall of the locking collar 4, a locking plate 8 is provided on one side of the locking collar 4, and a locking bolt 9 is installed through the center of the locking plate 8, a first transverse telescopic block 10 is provided on the other side of the locking collar 4, and a second transverse telescopic block 11 is provided on one side of the first transverse telescopic block 10;

[0029] A number of transverse anchoring holes 12 are installed at even intervals through the inner side of the second transverse telescopic block 11, and transverse anchoring bolts 13 are installed through the inner walls of the transverse anchoring holes 12. A number of vertical anchoring holes 29 are installed through the inner side of the vertical first telescopic rod 2 at even intervals, and vertical anchoring bolts 30 are installed through the inner walls of the vertical anchoring holes 29. A detection host 21 is provided on one side of the second transverse telescopic block 11, and a telescopic cylinder 22 is provided at the center of the lower end of the detection host 21. A telescopic shaft 23 is provided at the output end of the telescopic cylinder 22, and a mounting seat is provided at the lower end of the telescopic shaft 23. Hydraulic rods 24 are symmetrically provided at both ends of the mounting seat, and an arc block 25 is provided on one side of the hydraulic rod 24. A number of mounting holes 26 are opened at even intervals on the outer wall of the arc block 25, and a sliding ball 27 is installed on the inner wall of the mounting hole 26. An ultrasonic probe 28 is provided at the lower end of the mounting seat.

[0030] When using the pile foundation verticality detection instrument, first start the telescopic cylinder 22, and then drive the telescopic shaft 23 so that the large diameter cylinder in the telescopic cylinder 22 begins to extend outward by hydraulic pressure. After reaching the end of the stroke, the cylinder of the telescopic shaft 23 with a slightly smaller diameter begins to extend outward, and so on, until the cylinder of the smallest telescopic shaft 3 is extended, so that the mounting seat can be driven to make the ultrasonic probe 28 penetrate into the pile foundation hole. The ultrasonic probe 28 contains components such as piezoelectric crystals, which can convert electrical signals into ultrasonic signals, and convert the received ultrasonic signals into electrical signals and transmit them to the detection host 21 through wires. A control center is set in the detection host 21, which is responsible for receiving, processing and analyzing ultrasonic signals, and displaying the detection results. At the same time, the detection host 21 is equipped with a high-performance processor and a large-capacity storage device to ensure the accuracy and traceability of the detection results.

[0031] When the pile foundation verticality detection instrument is measuring the verticality of the pile foundation hole, and the height of the pile foundation hole casing is too high, the vertical first telescopic rod 2 and the vertical second telescopic rod 23 at both ends are manually adjusted so that they can reach an appropriate height, and then anchored by the vertical anchor bolts 30. When the diameter of the pile foundation hole casing is too large, the first transverse telescopic blocks 10 and the second transverse telescopic blocks 11 symmetrical at both ends are manually adjusted so that they can reach an appropriate width, and then fixed by the transverse anchor bolts 13. After adjusting the appropriate height and width, the locking collars 4 are respectively inserted into the vertical second telescopic rods 3 at both ends, and the fixing bolts 5 are inserted through the upper end of the vertical second telescopic rod 3, and anchored and clamped by the anchor bolts 7 and the clamping nuts 6 respectively, thereby avoiding the influence of the pile foundation hole edges of different sizes and heights, resulting in the inability to accurately measure the verticality of the pile foundation hole, and further improving the applicability.

[0032] Example 2

[0033] Reference Figure 1-4, which is the second embodiment of the present utility model, which differs from the first embodiment in that: a plurality of buffer cylinders 14 are evenly spaced on the inner side wall of the box body 1, and a buffer base 15 is provided on the inner bottom of each buffer cylinder 14, a buffer spring 16 is installed on the upper end of each buffer base 15, and a compression pad 17 is installed on the upper end of each buffer spring 16, a compression rod 18 is provided at the center of the upper end of the compression pad 17, and a buffer pad 19 is provided on the upper end of each compression rod 18, and a compression plate 20 is provided on the upper end of the buffer pad 19;

[0034] When there is vibration generated by construction in the surrounding area, and the pile foundation verticality detection instrument is placed next to the buried casing of the pile foundation hole, the force it bears is transmitted to the compression plate 20 through the vertical first telescopic rods 2 at both ends, and then the compression plate 20 compresses the buffer pad 17, so that the force is transmitted to the buffer spring 16 and the buffer cylinder 14 through the compression rod 18 and the compression pad 17. The buffer cylinder 14 is provided with a piston and two air chambers. When external vibration provides a certain pressure, the gas enters one air chamber of the compression rod 18 during the compression process, pushing the compression rod 18 to move to the other air chamber. In this process, as the compression rod 18 moves, the gas is compressed between the two air chambers. Due to the compressibility of the gas, the movement speed of the compression rod 18 will slow down, thereby achieving a vibration reduction and buffering effect, so that the vibration reduction and buffering device can avoid the influence of external factors such as collision and wind force during measurement, which may cause the measurement to be unable to occur. It also avoids the defects such as low measurement accuracy caused by the vibration generated by the surrounding construction, and further improves the judgment of the acceptance parameters.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
