Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engineering construction, in particular to a measuring device for inspecting the hole diameter of a cast-in-place pile. Background Art
[0002] Cast-in-place piles are a common foundation treatment method. They are created by forming a pile hole in the foundation soil, placing a steel cage inside, and then pouring concrete into the hole. Depending on the hole-forming method, cast-in-place piles can be divided into several categories: sunken-tube cast-in-place piles, bored cast-in-place piles, and excavated cast-in-place piles.
[0003] Cast-in-place pile construction technology has significant benefits in construction projects. It not only improves soil properties and enhances foundation stability, but also effectively controls ground settlement and compacts the soil. Cast-in-place piles effectively penetrate, compact, and split the soil, making it more stable. Furthermore, cast-in-place pile construction offers advantages such as zero vibration, no soil extrusion, and low noise, making it suitable for use in densely built-up urban areas.
[0004] The bore size of bored piles has an important influence on the bearing capacity and stability of the piles. In the existing technology, the bore size of bored piles is measured by lowering a column with several measuring legs. After lowering, the measurement is performed by measuring the spread of the legs, assisted by a displacement sensor. However, in actual applications, due to the uneven bore size of bored piles, when measuring at different depths, the spread measuring legs will be bumped and blocked when encountering a smaller bore size, resulting in inaccurate measurement or damage to components. There is room for improvement. Utility Model Content
[0005] The utility model aims to solve the above-mentioned technical problem that due to the uneven diameter of the bored pile, when measuring at different depths, the open measuring legs will be bumped and blocked when encountering a small diameter area, and provides a measuring device for inspecting the diameter of the bored pile.
[0006] In order to solve the above technical problems, the utility model provides a technical solution: a measuring device for inspecting the bore diameter of a cast-in-place pile, comprising symmetrically arranged cross braces, a plurality of columns being slidably arranged on the cross braces, a top plate being commonly connected to the upper ends of adjacent columns, and a lap plate being commonly connected to the upper ends of the top plates;
[0007] A measuring assembly is provided below the lap plate, and a lifting structure is provided between the measuring assembly and the lap plate. The lifting structure includes a first mounting plate and a second mounting plate symmetrically provided on the lap plate. A driving motor is provided on the first mounting plate, and a rotating rod is provided at the output end of the driving motor. The rotating rod is rotatably connected to the second mounting plate. Two sets of steel ropes are rotatably provided on the outer side of the rotating rod, and the steel ropes extend out of the lap plate and are connected to the measuring assembly.
[0008] The measuring assembly includes a connecting frame, a motor is provided on the connecting frame, an output end of the motor extends to the lower end of the connecting frame and a support rod is provided, a disc is provided at the lower end of the support rod, and a plurality of distance measuring sensors are evenly provided on the disc along the circumference.
[0009] Furthermore, the cross braces are all long strips and are placed on both sides of the cast-in-place piles.
[0010] Furthermore, the cross braces are provided with through slots, the through slots are provided with sliding rods, the lower ends of the columns are provided with sliding blocks, the sliding blocks are provided with through slots 2 that can accommodate the upper ends of the cross braces, and the sliding blocks are provided with through holes that can be slidably connected to the sliding rods and are lower than the through slots 2.
[0011] Furthermore, symmetrical hanging ears are provided on the upper end of the connecting frame, and the hanging ears are connected to corresponding steel ropes.
[0012] Furthermore, the lap plate is provided with a rectangular through groove capable of accommodating the steel rope.
[0013] The advantages of this utility model compared with the prior art are:
[0014] Measuring the aperture with a distance sensor not only improves measurement accuracy, but also makes it less likely to bump into something during the up and down movement process, and occupies less space in the cast-in-place pile.
[0015] After the measuring component is lowered into the cast-in-place pile, the position can still be fine-tuned to place it in the center of the hole, making it easier to measure. BRIEF DESCRIPTION OF THE DRAWINGS
