Description

Technical Field

[0001] This utility model relates to the field of grouting pile measurement technology, specifically a device for measuring the bottom diameter and enlarged width of a grouting pile. Background Technology

[0002] During the construction of cast-in-place piles, it is impossible to effectively measure the bottom pile diameter and enlarged base width on the ground to ensure they meet the design and drawing requirements. Furthermore, manual measurement at the bottom of the pile poses significant safety hazards. The bottom borehole width and the presence of enlarged base are crucial factors in controlling the construction quality and process acceptance of cast-in-place piles. How to effectively and safely measure the bottom pile diameter and enlarged base width has become a challenging problem for project management.

[0003] Based on this, the present invention proposes a device for measuring the bottom diameter and enlarged width of a cast-in-place pile. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model proposes a device for measuring the bottom diameter and enlarged width of cast-in-place piles. It can solve the problem of not being able to measure whether the bottom diameter and enlarged width of cast-in-place piles meet the requirements. It can adapt to the measurement requirements of pile holes of various depths and diameters, is reusable, has low manufacturing cost, minimal weight, and is easy to operate.

[0005] The technical solution to achieve the purpose of this utility model is: a device for measuring the bottom diameter and enlarged width of a cast-in-place pile, comprising flat iron, four of which are connected by four pins, and two adjacent flat irons are rotatably connected by pins; and further comprising:

[0006] The upper lifting ring is fixedly connected to the pin shaft, and the lower lifting ring is fixedly connected to the pin shaft. The upper lifting ring is fixedly connected to the second measuring rope, and the lower lifting ring is fixedly connected to the first measuring rope.

[0007] Preferably, two wristbands are fixedly connected to the first and second measuring ropes, respectively.

[0008] Preferably, the measuring rope is provided with a rope clip, the rope clip has a through hole, and the measuring rope is fixedly connected to the through hole.

[0009] Preferably, the rope clamp has a second through hole, and the second measuring rope passes through the second through hole.

[0010] Compared with existing technologies, the significant advantages of this invention are:

[0011] Firstly, in this utility model, the lowering, unfolding and lifting of the flat iron are controlled by measuring rope one and measuring rope two respectively. The operator only needs to operate the wristband on the ground to complete all the steps. No personnel need to enter the bottom of the pile, which fundamentally eliminates the extremely high safety risks such as suffocation and collapse caused by deep hole operation and solves the safety hazards during measurement.

[0012] Secondly, this utility model utilizes the mechanical property that flat iron automatically unfolds into a rhombus shape under gravity. By marking and restoring the displacement of the measuring rope, the pile diameter and the width of the enlarged base can be accurately calculated. One set of devices can be used to measure pile holes of different depths and diameters. Its structure is made of common materials such as flat iron, pin shaft and steel wire rope, with extremely low manufacturing cost. It can be reused, which greatly improves measurement efficiency and reduces project costs. Attached Figure Description

[0020] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0021] This utility model provides an improved device for measuring the bottom diameter and enlarged width of a cast-in-place pile. The technical solution of this utility model is as follows:

[0022] like Figures 1-4As shown, a device for measuring the bottom diameter and enlarged width of a cast-in-place pile includes flat iron 1, four flat irons 1 are connected to each other by four pins 2, and two adjacent flat irons 1 are rotatably connected by pins 2, and also includes;

[0023] The upper lifting ring 3 is fixedly connected to the pin 2. The lower lifting ring 4 is fixedly connected to the pin 2. The upper lifting ring 3 is fixedly connected to the measuring rope 6, and the lower lifting ring 4 is fixedly connected to the measuring rope 5. The lifting and lowering of the device is controlled by the measuring rope 5, and the contraction or expansion of the flat iron 1 is controlled by the measuring rope 6. This facilitates the measurement of the bottom pile diameter or the width of the expanded bottom, and can also simultaneously measure the depth of the pile hole.

[0024] Furthermore, such as Figure 1 and Figure 3 As shown, two wristbands 7 are fixedly connected to measuring rope 1 5 and measuring rope 2 6 respectively. The operator only needs to operate the wristbands 7 on the ground to complete the measurement without having to enter the bottom of the pile. This fundamentally eliminates the extremely high safety risks such as suffocation and collapse caused by deep hole operation and solves the safety hazards during measurement.

[0025] Furthermore, such as Figures 1-4 As shown, the measuring rope 5 is equipped with a rope clip 8, and the rope clip 8 has a through hole 9. The measuring rope 5 is fixedly connected in the through hole 9, and the rope clip 8 is used to prevent the measuring rope 6 from falling off.

[0026] Furthermore, such as Figures 1-4 As shown, the rope clamp 8 has a through hole 2 10, and the measuring rope 2 6 passes through the through hole 2 10. The diameter of the through hole 2 10 is larger than the diameter of the measuring rope 2 6.

[0027] The specific working method is as follows: After the pile drilling is completed, the device is slowly placed into the pile hole so that the pin 2 at the bottom of the device meets the bottom of the pile hole. Hold the two hand rings 7 and then slowly control the second measuring rope 6 to relax, so that the flat iron 1 gradually expands under the action of gravity and forms a rhombus shape, so that the pins 2 on both sides fit against the inner wall of the pile hole. At this time, mark the downward movement distance of the second measuring rope 6, and then move the second measuring rope 6 upward so that the flat iron 1 of the device retracts and returns to its original position. Then, lift the entire device out of the ground and restore the flat iron 1 to the same rhombus shape as when it was measured, according to the downward movement distance of the second measuring rope 6. Measure the width of the entire rhombus. The measured width is the bottom pile diameter or the width of the expanded bottom. The pile hole depth can also be measured at the same time.

[0028] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
