Description

Technical Field

[0001] This utility model relates to the technical field of pile foundation construction, and in particular to a pile cylinder deviation measuring device for pile foundation protection. Background Technology

[0002] A pile foundation is a deep foundation in which the tops of several piles are connected by a pile cap to form a whole to jointly bear dynamic and static loads. A pile is a vertical or inclined foundation component set in the soil. Its function is to penetrate soft, highly compressible soil layers or water and transfer the load borne by the pile to a harder, denser or less compressible bearing layer. The piles in a pile foundation are usually called pile foundations.

[0003] In existing technologies, because the pile casing of pile foundations is made of metal, it is prone to deformation and displacement under the disturbance of construction machinery. Therefore, before concrete construction, the deviation of the reinforcing steel and the casing opening must be measured to ensure smooth pile foundation construction. Currently, manual surveying is usually used, requiring at least three surveyors: one to stretch the string to measure the length of the X-axis, one to stretch the string to measure the length of the Y-axis, and one to stretch the measuring tape from the intersection of the X and Y axes to measure the radius of the pile casing. This measurement method is not only labor-intensive but also difficult to meet the accuracy requirements. Utility Model Content

[0035] Please see Figures 1 to 5 A pile cylinder deviation measuring device for pile foundation protection includes a first support rod 10 and a second support rod 20 arranged perpendicularly to each other, a first adjusting rod 30 slidably connected to the first support rod 10, and a second adjusting rod 40 slidably connected to the second support rod 20. The first adjusting rod 30 and the second adjusting rod 40 are arranged perpendicularly to each other. The second adjusting rod 40 is a telescopic rod, and one end of the second adjusting rod 40 away from the second support rod 20 is slidably connected to the first adjusting rod 30. It also includes a first pull wire assembly 50 slidably connected to the first support rod 10 and the second adjusting rod 40, and a second pull wire assembly 60 slidably connected to the second support rod 20 and the first adjusting rod 30. A measuring tape assembly 70 is slidably connected to the first pull wire assembly 50 or the second pull wire assembly 60.

[0036] This invention utilizes a slidingly connected first adjusting rod 30 and second adjusting rod 40. When it is necessary to measure the deviation of the pile cylinder, firstly, the first support rod 10 and the second support rod 20 are pressed against the outer wall of the pile cylinder. Then, the first adjusting rod 30 is slid along the first support rod 10 until it also presses against the outer wall of the pile cylinder. Since the second adjusting rod 40 is a telescopic rod, it will adaptively extend and retract when the first adjusting rod 30 is adjusted. Finally, the second adjusting rod 40 is slid along the second support rod 20 and the first adjusting rod 30 until it also presses against the pile cylinder. On the outer wall of the pile, the first support rod 10, the second support rod 20, the first adjusting rod 30, and the second adjusting rod 40 can frame the pile. The first support rod 10 and the second support rod 20 are used to determine the horizontal and vertical dimensions of the pile. Then, by sliding the first guy wire assembly 50 on the first support rod 10 and the second adjusting rod 40, and by sliding the second guy wire assembly 60 on the second support rod 20 and the first adjusting rod 30, the first guy wire assembly 50 and the second guy wire assembly 60 are both located at the center point of the pile. Finally, the radius of each position of the pile is measured starting from the center point of the pile using the tape measure assembly 70.

[0037] This invention allows for a simpler method of measuring the deviation of pile cylinders, greatly saving human resources.

[0038] The upper surfaces of the first support rod 10 and the second support rod 20 are both provided with scale marks 80. The surveyor can determine the horizontal and vertical dimensions of the pile tube according to the scale marks 80, and adjust the first pull wire assembly 50 and the second pull wire assembly 60 according to the scale marks 80 so that the two are located at the middle value of the scale marks 80, thereby quickly determining the center of the pile tube.

[0039] The first support rod 10 and the second support rod 20 are both provided with placement grooves 90 below them. The placement grooves 90 are used to mount the device on the upper surface of the pile tube. By setting the placement grooves 90, the device can be mounted on the pile tube more conveniently, thereby achieving the function of fixing it.

[0040] The second adjusting lever 40 includes a main lever 41 and a sub-lever 42 that slides within the main lever 41.

[0041] The first support rod 10 has a first groove 11 on the side facing the second adjusting rod 40, the second support rod 20 has a second groove 21 on the side facing the first adjusting rod 30, the first adjusting rod 30 has a third groove 31 on the side facing the second support rod 20, and the second adjusting rod 40 has a fourth groove 43 on the side facing the first support rod 10; the first adjusting rod 30 is slidably installed along the first adjusting rod 30, the main rod 41 is slidably installed along the second groove 21, and the sub-rod 42 is slidably installed along the third groove 31.

[0042] The first adjusting rod 30 has a slider at its end and is slidably installed in the first slide groove 11; the main rod 41 has a slider at its end and is slidably installed in the second slide groove 21; the sub-rod 42 has a slider at its end and is slidably installed in the third slide groove 31.

[0043] The fourth groove 43 between the main rod 41 and the sub-rod 42 is continuous.

[0044] The first pull wire assembly 50 includes a first winding structure slidably mounted along the first slide groove 11, a first fixing part 54 slidably mounted along the fourth slide groove 43, and a first pull wire 51 connecting the first winding structure and the first fixing part 54; the second pull wire assembly 60 includes a second winding structure slidably mounted along the second slide groove 21, a second fixing part 64 slidably mounted along the third slide groove 31, and a second pull wire 61 connecting the second winding structure and the second fixing part 64.

[0045] The first winding structure includes a first sliding block 52 slidably mounted along the first slide groove 11 and a first winding wheel 53 rotatably connected to the first sliding block 52, and a first pull wire 51 connected to the first winding wheel 53; the second winding structure includes a second sliding block 62 slidably mounted along the second slide groove 21 and a second winding wheel 63 rotatably connected to the second sliding block 62, and a second pull wire 61 connected to the second winding wheel 63.

[0046] When the position of the first pull wire assembly 50 needs to be adjusted, the first sliding block 52 is slid along the first slide groove 11 to the middle of the first support rod 10 within the pile cylinder range, and the first fixing part 54 is slid along the fourth slide groove 43 to the middle of the second adjusting rod 40. When adjusting the position of the second adjusting rod 40, the first winding wheel 53 will release the first pull wire 51. When the position of the second pull wire assembly 60 needs to be adjusted, the second sliding block 62 is slid along the second slide groove 21 to the middle of the second support rod 20 within the pile cylinder range, and the second fixing part 64 is slid along the third slide groove 31 to the middle of the first adjusting rod 30. When adjusting the position of the first adjusting rod 30, the second winding wheel 63 will release the second pull wire 61. When the first adjusting rod 30 and the second adjusting rod 40 are retracted, the first winding wheel 53 and the second winding wheel 63 can be manually moved to wind up the first pull wire 51 and the second pull wire 61.

[0047] The measuring tape assembly 70 includes a third winding wheel 72 that slides along a first pull line 51 or a second pull line 61, and a measuring tape 71 wound on the third winding wheel 72.

[0048] In this embodiment, the third winding wheel 72 is located on the first pull line 51. The third winding wheel 72 is slid along the first pull line 51 to the center of the pile cylinder at the intersection of the first pull line 51 and the second pull line 61. Then, the measuring tape 71 is pulled out from the third winding wheel 72 to measure the radius of each position of the pile cylinder. When retracting the measuring tape 71, the third winding wheel 72 can be manually moved.

[0049] This invention allows for a simpler method of measuring the deviation of pile cylinders, greatly saving human resources.
