[0001] The utility model relates to the technical field of bored cast-in-place pile construction, in particular to a device for measuring the elevation of concrete in a bored cast-in-place pile hole. Background Art
[0002] The control of underwater concrete pouring elevation of bored cast-in-place piles has a significant impact on the construction cost and quality of bored cast-in-place piles. Insufficient concrete pouring height in the hole will result in the pile top elevation not meeting the design specification requirements. Excessive concrete pouring height in the hole will cause concrete waste and increase construction costs.
[0003] Currently, the elevation of the concrete pouring surface within bored piles is mostly controlled using a hammer or rod. Relying on on-site experience, the hammer or rod is used to probe the concrete within the hole to determine the concrete pouring surface and, in turn, the concrete pouring surface elevation. However, this method is difficult to accurately control when measuring the concrete surface elevation within bored piles, relying solely on the on-site construction personnel's experience. This can result in insufficient or excessive concrete elevation within the bored pile hole. Utility Model Content

[0025] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).
[0027] The elevation of the concrete pouring surface in the bored pile hole is usually controlled by measuring with a hammer or a measuring rod. During the measurement process, the hammer or the measuring rod is touched to the surface of the concrete in the bored pile hole. This process is determined by the experience of on-site construction personnel and is prone to large human errors. Therefore, the accuracy of the measurement results is not high, which leads to insufficient or excessive concrete elevation.
[0028] In response to the above problems, the present application provides a device for measuring the elevation of concrete in bored cast-in-place pile holes to accurately measure the elevation of concrete in bored cast-in-place pile holes.
[0029] See also Figures 1-4 As shown, the device for measuring the elevation of concrete in a bored pile provided by the present application includes a sampling piece 10 and a kit 20 .
[0030] A sampling groove 11 is provided on the circumferential side of the sampling piece 10, and the interior of the sleeve 20 has a hollow chamber, one end of the hollow chamber is closed and the other end is open. In other words, the sleeve 20 is formed into a structure similar to a tube with one end closed. The sleeve 20 is arranged on the outside of the sampling piece 10, and the sleeve 20 and the sampling piece 10 can rotate relative to each other. In other words, the sleeve 20 can be rotated relative to the sampling piece 10, the sampling piece 10 can be rotated relative to the sleeve 20, or the sampling piece 10 and the sleeve 20 can be rotated at the same time. The specific selection can be made according to actual needs.
[0031] It is understood that the sampling member 10 is movably mounted within the hollow chamber, allowing the sleeve 20 to rotate relative to the sampling member 10. In a preferred embodiment, the sampling member 10 and the sleeve 20 may be rod-shaped structures, with the sampling groove 11 being a groove structure formed on the circumference of the sampling member 10 of the rod-shaped structure. The provision of the central control chamber allows the sleeve 20 to form a rod-shaped structure with one end closed and the other open. The sampling port 21 is a notch provided on the sleeve 20 of the rod-shaped structure, communicating with the hollow chamber.
[0032] In this embodiment, a sampling port 21 is provided on the peripheral side of the kit 20, and the sampling port 21 is connected to the central control chamber. After the kit 20 is put on the sampling piece 10, the sampling port 21 provided on the peripheral side of the kit 20 and the sampling slot 11 provided on the peripheral side of the sampling piece 10 correspond to each other.
[0033] By relatively rotating the kit 20 or the sampling piece 10, the kit 20 can close the sampling slot 11, that is, the sampling port 21 of the kit 20 is misaligned with the sampling slot 11, and the portion of the kit 20 where the sampling port 21 is not provided can be covered to the slot opening of the sampling slot 11, thereby closing the sampling slot 11. Alternatively, by relatively rotating the kit 20 or the sampling piece 10, the sampling port 21 and the sampling slot 11 at least partially overlap, and the sampling slot 11 can be opened through the sampling port 21.
[0034] In actual use, combined with Figure 5As shown, concrete 101 is poured in the casing 100 of the bored pile hole, wherein the original soil 102 is located below the poured concrete 101 in the casing 100. The kit 20 mounted on the sampling piece 10 is inserted into the concrete 101 in the casing 100 of the bored pile hole. Specifically, after being inserted into the concrete 101 in the casing 100 of the bored pile hole, the kit 20 continues to be inserted downward and extends into the original soil 102 so as to sample the bottom of the concrete 101, which is preferably the layer where the concrete 101 and the original soil 102 are combined.
[0035] In this embodiment, the sampling groove 11 is located at the bottom of the concrete 101 . It can be understood that the sampling groove 11 is located so that both the concrete 101 and the original soil 102 can be sampled.
[0036] When the sampling port 21 opens the sampling tank 11 , concrete can flow into the sampling tank 11 through the sampling port 21 . Afterwards, the kit 20 or the sampling piece 10 is relatively rotated so that the kit 20 closes the sampling groove 11, and the position where the upper surface of the concrete 101 cast in the casing 100 of the bored pile hole and the kit 20 or the sampling piece 10 overlap is calibrated on the kit 20 or the sampling piece 10, and the overlapping position is defined as the marking position 22, and the kit 20 sleeved on the sampling piece 10 is pulled out of the concrete 101 in the bored pile hole, and the present bored pile hole concrete elevation measuring device is placed flat, and the kit 20 or the sampling piece 10 is continued to be relatively rotated so that the sampling port 21 and the sampling groove 11 at least partially overlap, and the distance between the calibrated marking position 22 and the concrete sampled in the sampling groove 11 is measured, so that the elevation of the concrete 101 cast in the casing of the bored pile hole can be determined. Compared with the method of using manual experience to determine the position of the measuring rod extending into the concrete in the related art, the accuracy of the detection result can be effectively improved.
[0037] It is understood that the distance between the side of the concrete sampled in the sampling groove 11 close to the closed end of the kit 10 and the mark position 22 needs to be measured, that is, the elevation of the concrete poured in the casing 100 of the bored pile hole.
[0038] In order to enable the closed end of the kit 20 to be smoothly inserted into the concrete, Figures 1-4 As shown, the closed end of the sleeve 20 is a pointed end 22 to reduce the contact area between the insertion end of the sleeve 20 and the concrete, thereby reducing the friction generated during the insertion process, and thus the sleeve 20 can be smoothly inserted into the concrete.
[0039] See also Figure 3 As shown, a limiting portion 12 is provided on the sampling member 10 , and the limiting portion 12 is used to limit the opening of the sleeve 20 and make the sampling slot 11 correspond to the sampling port 21 .
[0040] In one embodiment, the limiting portion 12 is protruded from the sampling member 10 .
[0041] In this embodiment, at least two sampling slots 11 are provided on the circumference of the sampling member 10 , and at least two sampling ports 21 are provided on the circumference of the sleeve 20 . The at least two sampling ports 21 correspond one-to-one to the at least two sampling slots 11 .
[0042] like Figure 1-Figure 5 As shown, the sampling piece 10 is provided with a first hand-held portion 30 , which can facilitate construction workers to operate the sampling piece 10 to rotate.
[0043] Continue to see Figure 1-Figure 5 As shown, the kit 20 is provided with a second hand-held portion 40 , which can facilitate construction workers to operate the kit 20 to rotate.
[0044] like Figure 1 As shown, a rotation mark 50 is provided on the periphery of the sampling piece 10 and / or the kit 20. The rotation mark 50 is used to indicate whether the sampling port 11 and the sampling slot 21 coincide with each other, so as to facilitate the operator to operate the device inserted into the concrete.
[0045] See also Figure 1-Figure 3 As shown, the rotation mark 50 includes a misalignment mark 51, an overlap mark 52, and an indicator mark 53. The misalignment mark 51 and the overlap mark 52 are both arranged on the periphery of the sampling member 10. Along the length direction of the sampling member 10, the misalignment mark 51 extends in a direction misaligned with the sampling slot 11, and the overlap mark 52 extends through the sampling slot 11. The indicator mark 53 is arranged on the periphery of the sleeve 20. Along the length direction of the sleeve 20, the indicator mark 53 extends in a direction passing through the sampling port 21.
[0046] In actual use, the sampling piece 10 or the sleeve 20 is rotated relative to each other. When the extension direction of the misalignment mark 51 toward the sleeve 20 coincides with the extension direction of the indicator mark 53 toward the sampling piece 10, the sampling groove 11 and the sampling port 21 are misaligned. When the extension direction of the coincidence mark 52 toward the sleeve 20 coincides with the extension direction of the indicator mark 53 toward the sampling piece 10, the sampling groove 11 and the sampling port 21 at least partially coincide, and the sampling operation can be performed.
[0047] In this embodiment, the misalignment mark 51 and the overlap mark 52 are set on the sampling piece 10 near the opening of the kit 20, and the indication mark 53 is set on the kit 20 near the opening, so that the setting positions of the misalignment mark 51, the overlap mark 52 and the indication mark 53 are relatively closer, thereby facilitating observation by the operator.
[0048] To sum up, in the device for measuring the elevation of concrete in a suspended bored pile hole provided by the present application, the kit mounted on the sampling piece is inserted into the concrete poured in the casing of the bored pile hole, the concrete at the bottom of the poured concrete is taken out through the sampling trough, and the distance between the calibrated mark position and the concrete sampled in the sampling trough is measured, so as to determine the elevation of the concrete. Compared with the method of using manual experience to determine the position of the measuring rod extending into the concrete in the related art, the accuracy of the detection results can be effectively improved.
[0049] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
