Description

Technical Field

[0001] This utility model belongs to the field of building construction, and specifically relates to a device for measuring the verticality of pile foundation holes. Background Technology

[0002] A pile foundation is a columnar structure embedded in soil or rock that can be used to support buildings or other engineering structures. If the verticality of the pile foundation hole is insufficient, it will cause the pile foundation installation angle to deviate, which will cause problems with the support of the entire building.

[0003] During pile foundation construction, when re-measuring verticality, existing technologies often only allow measurement at one angle. If multiple angles need to be measured, the measuring device needs to be moved frequently, making the measurement process cumbersome. Utility Model Content

[0004] This utility model discloses a pile foundation hole verticality measuring device. By setting up a circular support and circling multiple sliding rods and corresponding sliders around the circular support, the device can measure the tilt angle at multiple angles at one time without frequently moving the measuring device.

[0005] A pile foundation hole verticality measuring device includes: a vertical pole; a horizontal pole, which is cantilevered from the top of the vertical pole and arranged in a horizontal direction; a circular bracket, which is fixed to the bottom of the cantilevered end of the horizontal pole, and the plane on which the circular bracket is located is a horizontal plane; a plurality of sliding rods, which are distributed and fixed to the outer periphery of the circular bracket along the circumference of the circular bracket, and each sliding rod extends outward along the radial direction of the circular bracket; a plurality of sliders, which are slidably mounted on the plurality of sliding rods; and a plurality of first laser lights, which are fixed to the bottom of the plurality of sliders, and the laser beam emitted by each first laser light extends in a vertical direction.

[0006] A further improvement of this utility model is that a second laser light is provided at the center of the bottom of the circular bracket, and the laser beam of the second laser light extends in the vertical direction.

[0007] A further improvement of this utility model is that it also includes a base fixed to the bottom end of the upright, and the base has an opening that can surround the outer periphery of the pile hole. When the opening surrounds the outer periphery of the pile hole with the center of the pile hole as the center, the circular bracket, multiple sliding rods and multiple sliding blocks are all located directly above the pile hole.

[0008] A further improvement of this invention is that the slide bar is marked with graduations.

[0009] A further improvement of this utility model is that each slider is provided with a limiting device for limiting the position of the slider.

[0010] A further improvement of this utility model is that the slider is frame-shaped and slidably framed on the surface of the slide rod. The limiting device includes: a threaded hole through the side wall of the slider; a fixing bolt screwed into the threaded hole, the fixing bolt being screwed into the threaded hole and abutting against the surface of the slide rod to limit the slider.

[0011] This utility model discloses a pile foundation hole verticality measuring device. By setting up a circular support and circling multiple sliding rods and corresponding sliders around the circular support, the device can measure the tilt angle at multiple angles at one time without frequently moving the measuring device.

[0016] like Figures 1-3 As shown, a pile foundation hole verticality measuring device includes: a vertical pole 21; a horizontal pole 22, which is cantilevered from the top of the vertical pole 21 and is set in a horizontal direction; a circular bracket 3, which is fixed to the bottom of the cantilevered end of the horizontal pole 22, and the plane on which the circular bracket 3 is located is a horizontal plane; a plurality of sliding rods 4 are distributed and fixed to the outer periphery of the circular bracket 3 along the circumference of the circular bracket 3, and each sliding rod 4 extends outward along the radial direction of the circular bracket 3; a plurality of sliders 5, which are slidably mounted on the plurality of sliding rods 4; and a plurality of first laser lamps 7, which are fixed to the bottom of the plurality of sliders 5, and the laser beam emitted by each first laser lamp 71 extends in a vertical direction.

[0017] like Figure 2 The circular support 3 is provided with a second laser lamp 72 at the center of its bottom end. The laser beam of the second laser lamp extends vertically. The placement of the second laser lamp 72 here facilitates the positioning of the device to the center of the pile hole.

[0018] like Figures 1-2The system also includes a base 1 fixed to the bottom end of the upright 21. The base 1 has an opening that can surround the outer periphery of the pile hole. When the opening surrounds the outer periphery of the pile hole with the center of the pile hole as the center, the circular bracket 3, multiple sliding rods 4 and multiple sliding blocks 5 are all located directly above the pile hole.

[0019] Preferably, in this embodiment, the base 1 is annular, and the inner ring is the opening in this embodiment.

[0020] In this embodiment, the slide bar 4 is marked with a scale. By setting the scale, the verticality can be calculated without the need for external measuring tools.

[0021] In this embodiment, as Figure 3 As shown, each slider 5 is equipped with a limiting device for limiting the position of the slider 5.

[0022] like Figures 1-3 As shown, the slider 5 is frame-shaped and slidably framed on the surface of the slider 4. The limiting device includes: a threaded hole through the side wall of the slider 5; and a fixing bolt 6 screwed into the threaded hole. The fixing bolt 6 is screwed into the threaded hole and abuts against the surface of the slider 4 to limit the slider 5.

[0023] In this embodiment, the base 1 is first placed at the pile hole to be measured. The device is then used to locate the side of the pile hole that slopes outwards. One of the sliders 5 on that side is moved, and its bottom laser light is turned on. The fixing bolt 6 is loosened to release the restriction on the slider 5. The slider 5 is moved until the first laser light 71 at the bottom illuminates the edge of the bottom of the pile hole. The scale corresponding to the position of the slider 5 at this time is recorded. The slider 5 is then moved again until the first laser light 71 illuminates the edge of the ground surface of the pile hole, and the scale corresponding to the position of the slider 5 at this time is recorded again. The difference between the two scale readings is denoted as X, and the depth of the pile hole is denoted as Y. The inclination angle can be calculated using X and Y. Multiple measurements are then performed using other sliders 5 to obtain multiple angle measurement results, thus determining the accurate verticality of the pile hole to be measured.

[0024] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
