Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a device for detecting over-pouring quality in cast-in-place piles. Background Technology
[0002] In modern construction engineering, cast-in-place piles are widely used as an important foundation type in the foundation construction of various buildings. During the construction of cast-in-place piles, over-pouring is a necessary operation to ensure the strength and density of the concrete at the pile top. However, the following problems currently exist in the detection of over-pouring quality in cast-in-place piles:
[0003] For the detection of the quality of overfilled concrete, most existing methods rely on experience and lack precise quantitative detection means. It is difficult to accurately identify whether there are quality defects such as segregation, honeycombing, and voids inside the concrete. These defects may have a serious impact on the overall performance and bearing capacity of the pile. Utility Model Content
[0004] The purpose of this utility model is to at least solve one of the technical defects described in the background art.
[0005] Therefore, one objective of this utility model is to propose a quality detection device for over-pouring in cast-in-place piles, which aims to solve the problem in the prior art that it is difficult to accurately identify whether there are quality defects such as segregation, honeycombing, and voids in the over-pouring concrete.
[0006] To achieve the above objectives, one embodiment of this utility model provides a device for detecting over-pouring quality in cast-in-place piles, comprising a transparent cylinder and multiple baffles. Multiple positioning sleeves are fixedly connected to the outer surface of the bottom end of the transparent cylinder. A pressure plate is fixedly connected to the outer surface of the baffles. A positioning block 1 is fixedly connected to the top of the pressure plate. The baffles are hinged inside the positioning sleeves via the positioning block 1. A traction rod is hinged to the end of the pressure plate away from the baffles. A pressure ring is slidably connected to the outer surface of the transparent cylinder. Multiple positioning blocks 2 are fixedly connected to the bottom of the pressure ring. The pressure ring is hinged to the top end of the traction rod via the positioning blocks 2.
[0007] The beneficial effects are as follows: After the concrete pile is poured, with multiple baffles unfolded and the bottom of the transparent cylinder open, the device is vertically and slowly inserted into the over-poured concrete, allowing the concrete to enter the interior of the transparent cylinder. Then, the pressure ring is pressed down, causing the multiple baffles to close and seal the bottom of the transparent cylinder, thus sealing the concrete inside. The transparent cylinder is then removed, and the concrete inside is observed to determine whether there are defects such as segregation, honeycombing, or voids, thereby achieving the purpose of quality inspection of the over-poured portion of the cast-in-place pile.
[0008] Preferably, in any of the above embodiments, a support block is fixedly connected to the outer surface of the transparent tube, a spring is fixedly connected to the top of the support block, the top end of the spring is fixedly connected to a pressure ring, a thread is provided on the outer surface of the top end of the transparent tube, a pressure sleeve is threadedly connected to the transparent tube through the thread at the top end, and an insertion hole is provided on the outer surface of the pressure sleeve.
[0009] The beneficial effects are as follows: the spring supports the pressure ring, causing multiple baffles to unfold, thus ensuring that the bottom of the transparent tube is open when the device is inserted into the concrete. After the device is inserted into the concrete, by rotating the pressure sleeve, it presses down on the pressure ring, causing multiple baffles to close and seal the bottom of the transparent tube, and the device can be pulled out. Therefore, there is no need to manually control the closing of the baffles during the insertion or removal process, making it more convenient to use.
[0010] Preferably, in any of the above embodiments, the outer surface of the transparent tube is provided with scale lines along its length.
[0011] The beneficial effects are as follows: by recording the insertion depth of the device and comparing it with the designed overfill height, it is possible to scientifically and reasonably determine whether the overfill height meets the requirements. If the overfill height is insufficient, concrete can be added in a timely manner to ensure the quality of the overfill.
[0012] Preferably, in any of the above embodiments, an inner cylinder is fixedly connected to the inside of the transparent cylinder, and an opening is provided on the side of the baffle away from the pressure plate.
[0013] The beneficial effects are as follows: when the device is inserted into the concrete, the concrete enters the transparent cylinder and the inner cylinder. Before it is pulled out, multiple baffles block the bottom end between the transparent cylinder and the inner cylinder. After it is pulled out, the concrete sample can be observed through the outside of the transparent cylinder and the inside of the inner cylinder. Observation from multiple angles can make the quality judgment more accurate.
[0014] Preferably, the bottom end of the inner cylinder is fixedly connected to a cone.
[0015] The beneficial effects are as follows: when the device is inserted into the concrete, the concrete is blocked by the cone and will not enter the interior of the inner cylinder, thus avoiding the problem of concrete sticking to the inner wall of the inner cylinder and being difficult to remove, and making it convenient to observe the quality of the concrete from inside the inner cylinder later.

[0028] This utility model provides a device for detecting over-pouring quality in cast-in-place piles.
[0029] Example 1:
[0030] like Figure 1-4As shown, it includes a transparent cylinder 1 and multiple baffles 2. Multiple positioning sleeves 11 are fixedly connected to the outer surface of the bottom end of the transparent cylinder 1. A pressure plate 21 is fixedly connected to the outer surface of the baffles 2. A positioning block 22 is fixedly connected to the top of the pressure plate 21. The baffles 2 are hinged inside the positioning sleeves 11 via the positioning block 22. The baffles 2 can rotate around the positioning sleeves 11 via the positioning block 22, allowing the multiple baffles 2 to unfold outwards, opening the bottom of the transparent cylinder 1. After the multiple baffles 2 rotate and converge, they can close the bottom of the transparent cylinder 1. A traction rod 3 is hinged to the end of the pressure plate 21 away from the baffles 2. A pressure ring 4 is slidably connected to the outer surface of the transparent cylinder 1. Multiple positioning blocks 41 are fixedly connected to the bottom of the pressure ring 4. The pressure ring 4 is hinged to the top of the traction rod 3 via the positioning blocks 41. Pulling the pressure ring 4 upwards pulls the pressure plate 21 via the traction rod 3, causing the multiple baffles 2 to unfold. Pressing the pressure ring 4 downwards allows the baffles to unfold. The traction rod 3 presses down the pressure plate 21, causing multiple baffles 2 to converge and seal the bottom of the transparent cylinder 1. A support block 12 is fixedly connected to the outer surface of the transparent cylinder 1, and a spring 13 is fixedly connected to the top of the support block 12. The top of the spring 13 is fixedly connected to the pressure ring 4, and the spring 13 supports the pressure ring 4, so that the pressure ring 4 can maintain a certain height when there is no external force. At this time, the multiple baffles 2 are in the unfolded state. When the pressure ring 4 is pressed down, the spring 13 is compressed, and the multiple baffles 2 will converge and seal the bottom of the transparent cylinder 1. The outer surface of the top of the transparent cylinder 1 is provided with a thread 14, and the transparent cylinder 1 is threadedly connected to the pressure sleeve 15 through the thread 14 at the top. Rotating the pressure sleeve 15 will press down the pressure ring 4, which will compress the spring 13, and the multiple baffles 2 will converge and seal the bottom of the transparent cylinder 1. The outer surface of the pressure sleeve 15 is provided with an insertion hole 16, which is convenient for inserting a pipe wrench to rotate the pressure sleeve 15.
[0031] Preferably, the outer surface of the transparent cylinder 1 is provided with scale lines 17 along its length. By recording the insertion depth of the device and comparing it with the designed overfilling height, it is possible to scientifically and reasonably determine whether the overfilling height meets the requirements.
[0032] The working principle of this embodiment is as follows: When in use, after the concrete pile is poured, with multiple baffles 2 unfolded and the bottom of the transparent cylinder 1 open, the device is vertically and slowly inserted into the over-poured concrete. The insertion depth of the device is determined by observing the scale line 17. When the predetermined depth is reached, the insertion is stopped. Then, the pressure sleeve 15 is rotated and the pressure ring 4 is pressed down, so that the multiple baffles 2 gather and close the bottom of the transparent cylinder 1. Then, the device is slowly pulled out of the concrete. After being pulled out, the outer wall of the transparent cylinder 1 is cleaned. Then, the quality of the concrete inside can be observed through the transparent cylinder 1, such as whether the color of the concrete is uniform and whether there are defects such as segregation, honeycomb, and holes. If a more detailed inspection is required, the transparent cylinder can be inverted and a concrete sample can be poured out for further testing and analysis, such as using professional testing equipment to measure the concrete strength, slump, and other indicators.
[0033] Example 2:
[0034] like Figure 5-7 As shown, based on Embodiment 1, an inner cylinder 5 is fixedly connected inside the transparent cylinder 1. A support rod 51 is fixedly connected to the outer surface of the top of the inner cylinder 5. One end of the support rod 51 is fixedly connected to the inner wall of the transparent cylinder 1 to achieve the purpose of fixing the inner cylinder 5 inside the transparent cylinder 1. The inner cylinder 5 is also made of transparent material. A notch 23 is opened on the side of the baffle 2 away from the pressure plate 21. When multiple pressure plates 21 are gathered and closed, the gap between the bottom of the transparent cylinder 1 and the inner cylinder 5 is sealed, but the bottom of the inner cylinder 5 is not sealed. Therefore, when the device is pulled out, there will be no concrete inside the inner cylinder 5.
[0035] In a preferred embodiment, a cone 52 is fixedly connected to the bottom end of the inner cylinder 5 to seal the bottom of the inner cylinder 5, thereby allowing the device to be inserted into the concrete without entering the inner cylinder 5, thus ensuring the cleanliness of the inner wall of the inner cylinder 5 and facilitating subsequent observation. In addition, the sharp bottom of the cone 52 can serve as a guide, with low resistance, making it easy for the device to be inserted into the concrete.
[0036] The working principle of this embodiment is as follows: When in use, by setting the inner cylinder 5, the sample is located between the transparent cylinder 1 and the inner cylinder 5 during sampling. Thus, not only can the quality of the concrete sample be observed through the outer surface of the transparent cylinder 1, but also the internal condition of the concrete sample can be observed through the inside of the inner cylinder 5. This multi-angle observation makes the quality judgment more accurate.
