Abstract
Description
Technical Field
[0001] The present application relates to the technical field of construction-related equipment, and particularly to a tool for measuring pile position deviation. Background Art
[0002] In pile foundation construction, measurement and positioning are crucial links. The accuracy of measurement and positioning directly affects the quality and stability of the pile foundation. Only by ensuring that the pile position is constructed according to the design drawings through measurement and positioning can the safety and quality of the building be guaranteed.
[0003] Before pile foundation construction, it is first necessary to accurately position the pile positions. In the past, in large construction sites, the site needed to be leveled before construction, and a total station was used to measure and set out the points; in cases where the site could not be leveled, there was no total station, or there were obstacles on the construction site that made measurement impossible, it was very difficult to set out the points, and the accuracy rate would also be greatly reduced; in some small construction sites, the method of using a plumb line was used to determine the axis position before construction. During the actual construction process, dimensional deviations are inevitable during both positioning and construction. According to relevant regulations and specification requirements: the allowable longitudinal and lateral position deviations of general piles (such as cast-in-place piles, precast piles) are usually 0.1 times the pile diameter, but not more than 100 mm. The allowable longitudinal and lateral position deviations of important projects or piles with high requirements for pile position accuracy (such as bridge piles, wharf piles) are usually 0.05 times the pile diameter, but not more than 50 mm. Therefore, pile position deviation measurement is one of the indispensable links in pile foundation construction. The common method is to measure the distance between the actual pile position and the axis, and then compare it with the design drawing to determine the pile position deviation.
[0004] During the actual measurement process, since it is difficult to determine the pile center, and the piles are mostly circular, a steel tape measure is usually used to measure the distance from the approximate position of the pile center to the axis, which may have an error from the actual pile center. The deviation value measured in this way is not accurate enough; and at least two people are required to perform the measurement operation, which is rather troublesome. Summary of the Utility Model

[0009] The first telescopic rod and the second telescopic rod in this application can adopt the structure of a measuring rod for height measurement or a similar structure; the stabilizing ring is used to be placed on the pile foundation. By adjusting the length of the first telescopic rod, all the first telescopic rods contract synchronously along the radial direction of the stabilizing ring. When the outer ends of all the first telescopic rods are flush with the outer peripheral surface of the pile foundation, the center of the stabilizing ring can be made to coincide with the pile center. The radius of the pile foundation is measured by the first scale, and then the length of the second telescopic rod is adjusted. The distance between the first telescopic rod and the axis is measured by the second scale on the second telescopic rod.

[0052] Combined Figure 3 As shown, at the connection end of the first telescopic rod 20 and the second telescopic rod 40 in the present application, there is a downward abutting buckle 80 for buckling the pile body.
[0053] Referring to Figure 4 and Figure 5 As shown, a transmission structure 90 for keeping all the first telescopic rods 20 telescoping synchronously is arranged in the stabilizing ring 10. The transmission structure 90 can be fixedly connected to the fixed rod 60 in the stabilizing ring 10; the transmission structure 90 includes a chassis 91 and a top cover 92. A rotating shaft 93 is vertically arranged in the middle of the chassis 91, and a central gear 94 and four planetary gears 95 meshing with the central gear 94 are fixedly arranged on the rotating shaft 93. The top cover 92 is fixedly arranged on the chassis 91. The central gear 94 and the planetary gears 95 are located in the enclosed space between the chassis 91 and the top cover 92. A swing rod 96 is fixedly connected to each planetary gear 95; four sliding grooves 913 are formed in the upper side of the chassis 91 and the four sliding grooves 913 enclose a square; a slider 97 is slidably arranged in each sliding groove 913, and the sliders 97, the first telescopic rods 20 and the swing rods 96 are arranged in one-to-one correspondence. The end of the slider 97 is connected to the inner rod of the corresponding first telescopic rod 20 through a connecting rod 99; a notch or through hole can be formed in the stabilizing ring 10 for the connecting rod 99 to slide through and then be connected to the slider 97. The slider 97 is movably connected to the corresponding swing rod 96, and the linear sliding of the slider 97 and the swinging of the swing rod 96 can drive each other. Specifically, a first installation groove 911 is formed in the middle of the chassis 91, and four second installation grooves 912 are formed around the first installation groove 911. The four second installation grooves 912 are evenly spaced along the circumferential direction of the first installation groove 911 and the first installation groove 911 communicates with the second installation grooves 912. The central gear 94 is installed in the first installation groove 911, and the four planetary gears 95 are respectively installed in the four second installation grooves 912. One end of the swing rod 96 is fixedly connected to the end of the corresponding planetary gear 95, and a kidney-shaped hole 961 along the length direction of the swing rod 96 is formed in the other end of the swing rod 96. A connecting pin 98 inserted into the kidney-shaped hole 961 is arranged on the slider 97. When adjusting the length of any one of the first telescopic rods 20, the first telescopic rod 20 drives the corresponding slider 97 to move synchronously through the connecting rod 99.

The upper end of the pile core rod 70 is connected to the fixed rod 60, and the lower end of the pile core rod 70 passes through the rotating shaft 93.
[0055] The implementation principle is as follows: The stabilizing ring 10 in this application is used to be placed on the pile foundation. Before use, the pile diameter is initially evaluated. The first telescopic rod 20 is adjusted to be slightly longer than the radius of the pile foundation, and one of the second telescopic rods 40 of the pile position deviation measuring tool is aligned with the reference axis of the deviation to be measured. When determining the pile core, the first telescopic rod 20 is contracted inward until the abutting buckles 80 at the outer ends of all the first telescopic rods 20 abut against the outer peripheral surface of the pile body, that is, the automatic centering of the center of the stabilizing ring 10 and the pile core is realized. Furthermore, the position of the pile core can be conveniently, quickly and accurately positioned, and the measuring tool can also be fixed by clamping the outer peripheral surface of the pile body along the circumferential direction of the pile foundation by multiple abutting buckles 80. The radius R of the pile foundation can be directly read according to the scale value on the first telescopic rod 20. The length of the second telescopic rod 40 is adjusted to measure the distance L from the first telescopic rod 20 to the axis, and then the distance E between the pile core and the axis is calculated as E = L + R. Finally, the measured distance is compared with the design drawing to determine the pile position deviation and judge whether the requirements are met.
[0056] The overall structure of the measuring tool in this application is simple and compact; the first telescopic rod 20 is used to clamp the pile body and can measure the pile diameter. The operator only needs to adjust the length of any one of the first telescopic rods 20 to realize the automatic centering of the stabilizing ring 10 and the pile body, so as to determine the position of the pile core. The operation is convenient and fast, greatly improving the detection efficiency, and it is accurate and reliable; in addition, the above-mentioned measuring tool can be operated by one person, saving labor costs.
