Description

Technical Field

[0001] This utility model relates to the field of pile foundation engineering construction technology, and in particular to a tool for measuring and positioning the depth of pile holes during casing construction. Background Technology

[0002] In the process of drilling piles with casing, hole depth measurement is a key link in quality control, which directly affects the bearing capacity of the pile foundation, sediment control, and pile quality.

[0003] In the existing casing construction pile hole depth measurement, the traditional manual rope measuring method is limited by the operator's technical level. It is easy to cause data deviation due to rope bending or tilting, making it difficult to accurately reflect the actual hole depth. Especially for large-diameter pile foundations, when it is necessary to accurately determine the depth of local positions at the bottom of the hole, manual measurement not only has insufficient positioning accuracy, but may also further reduce reliability due to factors such as rope friction with the hole wall and mud interference, seriously affecting the pile quality and acceptance standards of large-diameter piles. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model proposes a tool for measuring and positioning the depth of pile holes during casing construction. A square steel support is placed above the casing. The square steel support can be lengthened or shortened using connecting bolts to accommodate casings of various diameters. A rotating wheel is inserted into a T-shaped connector, which is fixed to the square steel support using positioning bolts. This ensures that the T-shaped connector and the rotating wheel can be fixed at any position on the square steel support. A limiting member is connected to the square steel support using fixing bolts, allowing the square steel support to rotate. The limiting member is also connected to the casing and fixed using adjusting bolts. Through the combination of the square steel support and the rotating wheel, the measurement of the depth of pile holes during casing construction can be effectively completed.

[0005] The technical solution to achieve the purpose of this utility model is: a tool for measuring and positioning the hole depth of a casing construction pile, comprising two square steel supports, each of which is equipped with a T-shaped connector, and further comprising;

[0006] A positioning mechanism, wherein the positioning mechanism is located on a square steel support;

[0007] The positioning mechanism includes insertion holes on two T-shaped connectors, with a rotating wheel installed on both insertion holes. A measuring rope is installed on the rotating wheel. Two square steel supports are fixed to the two T-shaped connectors respectively by positioning bolts. A limiting member is provided below the two square steel supports. The two square steel supports and the limiting member are fixed by fixing bolts. The limiting member has multiple movable holes, and an adjusting bolt is installed in each of the multiple movable holes.

[0008] In some embodiments, the limiting member is U-shaped.

[0009] In some embodiments, the wheel is equipped with a rotating handle.

[0010] In some embodiments, both square steel supports are provided with multiple mounting holes, and connecting bolts are installed in each of the multiple mounting holes.

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

[0012] This utility model places a square steel support above the casing. The square steel support can be lengthened or shortened using connecting bolts to accommodate casings of various diameters for construction measurements. A rotating wheel is inserted into a T-shaped connector, which is fixed to the square steel support using positioning bolts. This ensures that the T-shaped connector and the rotating wheel can be fixed at any position on the square steel support. A limiting member is connected to the square steel support using fixing bolts, allowing the square steel support to rotate. The limiting member is connected to the casing and fixed using adjusting bolts. Through the combination of the square steel support and the rotating wheel, the depth measurement of the casing construction pile hole can be effectively completed during construction. It features accurate positioning, a large measurement coverage area, convenient installation and dismantling, and reusability. This avoids wasting unnecessary measurement and positioning time due to construction quality requirements, thus improving overall construction efficiency and ensuring construction quality.

[0013] This method solves the problem that traditional manual rope measuring methods are limited by the operator's skill level, and are prone to data deviation due to rope bending or tilting, making it difficult to accurately reflect the actual hole depth. Especially for large-diameter pile foundations, when it is necessary to accurately determine the depth of local positions at the bottom of the hole, manual measurement not only lacks positioning accuracy, but may also be further reduced in reliability due to factors such as friction between the measuring rope and the hole wall and mud interference, which seriously affects the pile quality and acceptance standards of large-diameter piles.
