Description

Technical Field

[0001] This utility model relates to the field of cast-in-place pile construction technology, and in particular to a combined ruler for measuring the diameter of cast-in-place pile holes. Background Technology

[0002] Measurement of cast-in-place piles is carried out throughout the entire construction process and is a core link in ensuring the safety and quality of pile foundation projects. In order to avoid pile defects (neck, broken pile, segregation, etc.) from affecting the bearing capacity, the measurement of the diameter of cast-in-place pile holes is even more rigorous.

[0003] A search revealed Chinese patent CN206495243U, which discloses a device for detecting the diameter of pile holes in foundation pits, solving the problems of cumbersome procedures and large measurement errors in pile hole measurement. The device includes a pile hole, a horizontal bar, a vertical bar, and a total station. The horizontal and vertical bars are fixed together at a cross intersection. A vertical sleeve is installed at the cross intersection point, and a centering rod of the total station is inserted into the vertical sleeve. A horizontal scale is installed on the horizontal bar, and a vertical scale is installed on the vertical bar. This invention is simple to use and can quickly and accurately detect pile diameter and pile position deviations, improving the quality of pile hole formation.

[0004] Based on the above search and existing technology, the following findings were made:

[0005] The aforementioned patent search measurement is inefficient, requires the assembly of multiple components, has a complex operation process, and poor environmental adaptability. In the mud-filled pile environment, the accuracy of optical measurement is difficult to guarantee. In addition, it relies on expensive equipment, resulting in high costs, and therefore has certain limitations. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a combined ruler for measuring the diameter of cast-in-place pile holes, which efficiently and accurately solves the problem of measuring the bottom diameter and depth of cast-in-place piles.

[0007] The technical solution to achieve the purpose of this utility model is: a combined ruler for measuring the diameter of a cast-in-place pile hole, including a rectangular ruler and a measuring component.

[0008] The measuring component includes scale lines fixedly mounted on the surface of a rectangular ruler.

[0009] Preferably, a foldable telescopic frame is fixedly installed on both sides of the bottom of the rectangular ruler, and a sliding groove is provided on the rectangular ruler, with pins slidably installed on both sides of the inner side of the sliding groove.

[0010] Preferably, each of the pins is provided with a steel wire rope near its bottom end, the steel wire rope is fitted with an adjusting fastener, and a plumb bob is fixedly installed at the bottom of the steel wire rope.

[0011] Compared with existing technologies, the significant advantages of this invention are:

[0012] Firstly, this utility model is used for efficient and simple measurement of the diameter and depth of cast-in-place pile holes. It can adapt to the inspection and measurement requirements of cast-in-place piles with different diameters and hole depths. It is reusable, has low manufacturing cost, minimal weight, and is easy to carry and operate.

[0013] Secondly, the foldable telescopic frame design of this utility model improves stability. In addition, the measuring system composed of steel wire rope and plumb bob enables simultaneous measurement of aperture and depth. At the same time, the fasteners can be adjusted to fine-tune the measurement accuracy, and the length of the steel wire rope can be adjusted according to the depth.

[0014] It solves the problems of low measurement efficiency, need to assemble multiple components, complex operation process, poor environmental adaptability, difficulty in guaranteeing optical measurement accuracy in mud-filled pile environment, and high cost due to reliance on expensive equipment.

[0021] 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.

[0022] This utility model provides an improved combination ruler for measuring the diameter of cast-in-place pile holes. The technical solution of this utility model is as follows:

[0023] Example 1

[0024] like Figure 1As shown, a combined ruler for measuring the diameter of cast-in-place pile holes includes a rectangular ruler 1, which has low manufacturing cost, minimal weight, and is easy to carry, and also includes measuring components:

[0025] The measuring components include scale lines 7 fixedly mounted on the surface of a rectangular ruler 1, providing clear measurement results and a simple and easy-to-understand measurement process.

[0026] Example 2:

[0027] Based on the combined ruler for measuring the diameter of cast-in-place piles provided in the first embodiment of this application, the second embodiment of this application proposes another combined ruler for measuring the diameter of cast-in-place piles. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0028] The second embodiment of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0029] like Figures 2-3 As shown, a foldable telescopic frame 6 is fixedly installed on both sides of the bottom of the rectangular ruler 1. A sliding groove 8 is provided on the rectangular ruler 1. Pins 2 are slidably installed on both sides of the inside of the sliding groove 8. The pins 2 pass through the sliding groove 8 of the rectangular ruler 1, and the upper part is a large end to prevent the pins 2 from sliding out.

[0030] Furthermore, each pin 2 is equipped with a steel wire rope 4 near its bottom. An adjusting buckle 3 is fitted on the steel wire rope 4, and a plumb bob 5 is fixedly installed at the bottom of the steel wire rope 4. The upper part of the steel wire rope 4 is connected to the pin 2. By moving the pin 2, the left and right movement of the steel wire rope 4 and the plumb bob 5 can be controlled. The adjusting buckle 3 can change the degree of slump of the steel wire rope 4 according to the depth, further improving the practicality of the device.

[0031] The specific working method is as follows: First, after the drilling of the cast-in-place pile is completed, slowly lower the steel wire rope 4 and the plumb bob 5 of this combination ruler into the pile hole. When the plumb bob 5 falls to the bottom of the pile, hold the rectangular ruler 1, open the telescopic support to keep the measurement stable and keep the rectangular ruler 1 clean and clear; second, adjust the position of the pin 2 so that the steel wire rope 4 and the plumb bob 5 are close to the pile hole wall; according to the position of the pin 2, read the pile hole diameter on the rectangular ruler 1; finally, mark the position of the steel wire rope 4 entering the hole, and slowly pull out the steel wire rope 4 and the plumb bob 5. Measure the hole depth according to the length of the steel wire rope 4 that has fallen into the hole.
