Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a device for measuring the over-pouring height of underwater pile concrete. Background Art

[0002] During underwater pile pouring, to ensure the quality and stability of the pile foundation, the overfill height of the concrete must be precisely controlled, directly impacting the pile's quality and bearing capacity. Controlling the pouring height of underwater concrete has always been a challenge for construction workers. In actual projects, the top of the pile is typically below ground level, sometimes as deep as 10 meters, while the overfill depth is typically limited to 1-3 meters. For large-scale projects with numerous pile foundations, the overfilled concrete and subsequent pile head chiseling and removal increase construction costs and result in significant waste of resources.

[0003] At present, the height of cast-in-place pile concrete is generally measured by wire rope and counterweight head. The concrete liquid level is judged by the feedback touch of the wire rope connected to the counterweight head. It needs to rely on the long-term experience accumulation of operators to make judgments. It is easily affected by factors such as operator experience, end touch, and counterweight type. There are large deviations and it is not universal.

[0004] Therefore, it is particularly important to develop a device for measuring the overfilling height of underwater pile concrete that is simple to operate and accurate in measurement. Utility Model Content

[0029] like Figure 1 and Figure 3 As shown, a device for measuring the overfilling height of underwater pile concrete includes a fixed benchmark 1 and a hopper 2. The hopper 2 is installed at the bottom end of the fixed benchmark 1, and the fixed benchmark 1 is provided with a scale.

[0030] As an example, an embodiment of the present application provides a device for measuring the overfilling height of underwater pile concrete, comprising a fixed ruler 1 and a hopper 2. The hopper 2 is mounted on the bottom end of the fixed ruler 1, and the bottom surface of the hopper 2 is flush with the bottom end surface of the fixed ruler 1. The fixed ruler 1 is a hard ruler, and a scale is provided along its length. When measuring the overfilling height of underwater pile concrete, the operator holds the top of the fixed ruler 1, and then slowly sinks the bottom end of the fixed ruler 1 into the cast-in-place pile. As the hopper 2 passes from a low-density liquid medium to a high-density liquid medium material, a significant change in buoyancy will occur, and the force will be transmitted to the operator's hand through the hard fixed ruler 1, thereby providing the operator with a clear and direct sense of touch. Feedback: When the hopper 2 passes through the mud layer on the upper part of the bored pile and reaches the concrete stopping surface, the operator can sense the significant increase in buoyancy through the tactile feedback of the fixed benchmark 1. From this, it can be judged that the bottom surface of the hopper 2 has bottomed out and reached the stopping surface, that is, the top of the underwater pile foundation; at this time, the operator can accurately and directly measure the depth of the concrete stopping surface or the top of the pile foundation by reading the scale on the fixed benchmark 1, and learn about the over-filling situation, so as to reduce problems such as insufficient concrete filling or excessive over-filling height at the pile top, which is beneficial to construction quality control. After the measurement is completed, the operator can also salvage and extract concrete aggregates through the hopper 2 to verify the bottoming measurement operation; at the same time, check the concrete quality, coarse aggregate ratio and other pouring conditions at the interface of the pile top. After use, it can also be easily cleaned and maintained for the next use.

[0031] The advantages of the underwater pile concrete over-pouring height measuring device of this embodiment are: simple operation, obvious tactile feedback, can improve measurement accuracy and reliability of measurement results, facilitate accurate control of over-pouring height and management of construction quality, while ensuring the concrete strength of the pile foundation head, strictly control the amount of concrete used, reduce concrete waste, save project cost, high practicality and strong scalability.

[0032] In one embodiment, see Figure 1 and Figure 3 , hopper 2 is a flat bottom structure.

[0033] As an example, the bottom surface of the hopper 2 of this embodiment is set to a flat bottom structure, which is convenient for sensing buoyancy changes and providing accurate tactile feedback and bottoming judgment.

[0034] In one embodiment, see Figure 1 and Figure 3 The hopper 2 is provided with a filtering hole 201 .

[0035] As an example, filter holes 201 are provided on the side walls and bottom of the hopper 2. The aperture of the filter port is smaller than the particle size of the concrete aggregate. In this embodiment, the aperture of the filter hole 201 is preferably 10 mm, which facilitates the rapid discharge of the mud in the hopper 2 while retaining the concrete aggregate.

[0036] In one embodiment, see Figure 2 and Figure 3 The underwater pile concrete overfilling height measuring device also includes an extended benchmark ruler 3, on which a scale is set, and the extended benchmark ruler 3 is detachably connected to the top of the fixed benchmark ruler 1.

[0037] As an example, to accommodate the measurement requirements of underwater pile foundations at varying depths, the underwater pile concrete overfill height measurement device of this embodiment is further designed with multiple extension rods 3, each provided with graduations. The extension rods 3 are detachably connected to the top of the fixed rod 1. By adding multiple extension rods 3, the overall length of the measurement device can be flexibly adjusted to accommodate the measurement requirements of underwater piles at varying depths.

[0038] In one embodiment, see Figure 2 and Figure 3 One end of the extended benchmark ruler 3 is provided with an internal threaded hole and the other end is provided with an external thread; the top of the fixed benchmark ruler 1 is provided with an internal threaded hole or an external thread, and the extended benchmark ruler 3 is connected to the top of the fixed benchmark ruler 1 through internal and external threads.

[0039] As an example, one end of the extended ruler 3 is provided with an internal threaded hole and the other end is provided with an external thread, while the top end of the fixed ruler 1 is provided with an internal threaded hole that matches the external thread of the extended ruler 3. The extended ruler 3 and the fixed ruler 1 are connected by internal and external threads to achieve extension. At the same time, the external threaded end of the extended ruler 3 can also be connected to other extended rulers 3 through internal and external threads to achieve further extension. This connection method is simple and reliable, and is convenient for quick installation and removal. Similarly, in other embodiments, the top end of the fixed ruler 1 can also be provided with external threads that match the internal threaded hole of the extended ruler 3 to achieve the same internal and external thread connection and extension effect.

[0040] In one embodiment, the fixed measuring rod 1 and the extended measuring rod 3 are both hollow structures.

[0041] As an example, the fixed benchmark ruler 1 and the extended benchmark ruler 3 are both hollow structures, which can reduce the mass of the benchmark rulers and improve the sensitivity of tactile feedback; at the same time, the bottom end of the fixed benchmark ruler 1 is a closed structure to prevent mud and concrete from being injected.

[0042] In one embodiment, the fixed ruler 1 and the extended ruler 3 are both made of aluminum.

[0043] As an example, the fixed ruler 1 and the extended ruler 3 are both made of aluminum. The wall thickness of the hollow structure ruler is about 5 mm. Since the density of aluminum is less than 2.7 g / cm 3 Close to the mud density, during the measurement of mud wall pile foundation, the measuring device can reach a suspended state close to the buoyancy balance, making the bottoming buoyancy change more obvious and improving the measurement accuracy.

[0044] In one embodiment, the scale lengths of the fixed ruler 1 and the extended ruler 3 are both 1 meter.

[0045] As an example, the scale lengths of the fixed benchmark ruler 1 and the extended benchmark ruler 3 are both set to 1 meter. This design is convenient for reading and can shorten the occupied space after disassembly, making it easy to carry.

[0046] In one embodiment, see Figure 1 and Figure 3 The underwater pile concrete over-filling height measuring device also includes a clamping part 4, which is nested on the fixed benchmark ruler 1. A first connecting hole is opened at both ends of the clamping part 4, and the hopper 2 is provided with a second connecting hole corresponding to the position of the first connecting hole. The first connecting hole and the second connecting hole are connected by bolts and nuts to realize the fixed connection between the hopper 2 and the fixed benchmark ruler 1.

[0047] As an example, to achieve a secure connection between the hopper 2 and the fixed scale bar 1, this embodiment employs a clamping member 4. The clamping member 4 utilizes a U-shaped saddle clip and is nested within the fixed scale bar 1. The clamping member 4 has first connection holes at both ends, and the hopper 2 has second connection holes corresponding to the first connection holes. The first and second connection holes are connected by bolts and nuts to securely connect the hopper 2 to the fixed scale bar 1. This connection is not only secure and reliable, but also facilitates replacement of the hopper 2. In other embodiments, welding, screwing, and other fixing methods may also be employed.

[0048] In one embodiment, see Figure 1 and Figure 3 An anti-slip pad 5 is provided between the clamping member 4 and the fixed benchmark ruler 1.

[0049] As an example, in order to prevent the hopper 2 from loosening or falling off during the measurement process, this embodiment also provides an anti-slip pad 5 between the clamping member 4 and the fixed benchmark ruler 1, which can effectively increase the friction between the two and ensure that the clamping member 4 can firmly tighten the hopper 2 and the fixed benchmark ruler 1.
