Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pile head concrete measurement, in particular to a bored pile head concrete measurement device. Background Art
[0002] Bored cast-in-place piles refer to piles made by forming a pile hole in the foundation soil at the construction site through mechanical drilling, steel pipe squeezing or manual excavation, and then placing a steel cage inside and pouring concrete. According to different hole-forming methods, cast-in-place piles can be divided into several categories, such as sunken pipe cast-in-place piles, bored cast-in-place piles and excavated cast-in-place piles. When the concrete of bored piles for bridges is about to be poured to the designed elevation, the mud sediment accumulates more and more and mixes with the concrete. The traditional measuring rope device has become inaccurate, resulting in either poor pile head quality or serious concrete over-cubicity. To solve the above problems, a bored pile head concrete measuring device is proposed. Utility Model Content
[0003] In response to the above technical problems, the utility model provides a bored pile head concrete measuring device, which is characterized by comprising a measuring head, a connecting rod, a sleeve, an upper handle, a limit frame, and a limit cylinder, wherein the measuring head is provided with a connecting rod, the connecting rod is arranged in the sleeve, the upper handle is arranged in the sleeve, the upper handle is provided with a scale, the limit cylinder is arranged outside the sleeve, and the limit cylinder is arranged on the limit frame;
[0004] Furthermore, the measuring head is composed of four steel bars with a diameter of 6 mm, the connecting rod is fixedly connected to the measuring head, the two ends of the sleeve each have a threaded opening, the end of the connecting rod is threadedly connected to the sleeve, the upper handle is threadedly connected to the sleeve, and the upper handle and the connecting rod are made of steel bars with a diameter of 12 mm;
[0005] Furthermore, a limiting cylinder is fixedly provided on the limiting frame, and a through opening is provided in the limiting cylinder;
[0006] Furthermore, the measuring head, connecting rod, sleeve, upper handle, limit frame and limit cylinder are all coated with a zinc-chromium anti-corrosion layer.
[0007] Beneficial effects of the utility model:
[0008] The utility model inserts the upper handle into the lower 30cm of the limit cylinder of the limit frame, connects it and connects it with the sleeve threadedly at the bottom, then connects the connecting rod and the measuring head through the thread at the bottom of the sleeve, and then vertically and slowly inserts it into the hole. When the hand resistance is uniform, it indicates that it has been inserted into the fresh concrete. When the upper handle is pulled out, it can be seen that the concrete mortar on the measuring head and the connecting rod is evenly arranged, and the scale on the top of the sleeve is read. At this time, the concrete gap can be calculated by simple calculation according to the elevation of the limit cylinder, and the concrete is poured to the length of the gap, and the root pile is poured. The utility model has low cost, simple assembly, easy operation, suitable size, safe use, and certain flexibility. It can accurately measure the height of the pile head concrete, thereby ensuring the quality of the pile head is intact, saving concrete consumption, and reducing construction costs. In addition to being used for bored piles for bridges, it can also be used for bored piles in other terrains. They are all coated with a zinc-chromium anti-corrosion layer, which can effectively avoid rust and increase service life. BRIEF DESCRIPTION OF THE DRAWINGS
