Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and specifically relates to a concrete liquid level measuring device for bored cast-in-place piles. Background Technology

[0002] In existing technologies, bored piles are widely used in the field of construction engineering. Their quality directly affects the overall quality of the construction project. Bored pile construction technology has advantages such as no vibration hazards, no noise, no soil compression, fast construction, and high load-bearing capacity. It saves time, ensures quality, and is easy to construct.

[0003] Over-pouring is a common phenomenon in bored pile construction. To ensure pile quality, concrete is often poured beyond the design elevation by a certain height. However, current methods for detecting over-pouring height typically rely on manual methods, measuring the depth of the concrete layer by suspending a weight on a measuring rope. This method is susceptible to the influence of the muddy layer above the concrete surface, leading to significant errors. Furthermore, these errors make it difficult for workers to control the pouring height, resulting in substantial over-pouring and increased construction costs. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a concrete liquid level measuring device for bored piles, thereby solving the technical problem of large measurement errors in existing concrete liquid level measuring devices.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A concrete liquid level measuring device for bored piles includes a base assembly and a measuring assembly. The base assembly includes a base body and a supporting rod. The supporting rod is fixed to the top of the base body and extends outward in a horizontal direction. A sliding sleeve that mates with the measuring assembly is fixed to the outer end of the supporting rod.

[0006] The measuring assembly includes a measuring rod and a liquid measuring plate fixed to the bottom of the measuring rod. The measuring rod slides in conjunction with a sliding sleeve and can move freely in the vertical direction. A graduated scale is provided on the outer side of the measuring rod; a sampling square tube is fixed on the top surface of the liquid measuring plate.

[0007] Furthermore, multiple weight blocks are fixed on the liquid measuring plate.

[0008] Furthermore, a horizontally positioned limiting rod is fixed to the top of the measuring rod.

[0009] Furthermore, the base body includes an upper fixing rod and a lower triangular support. The top end of the fixing rod is welded and fixed to the inner end of the supporting connecting rod. The triangular support includes an outer frame and a connector fixed at the center of the outer frame. The bottom of the fixing rod is welded and fixed to the connector.

[0010] Furthermore, the outer frame has a triangular structure. Angle steel is used for the connectors.

[0011] Furthermore, an auxiliary support rod is fixed at each of the three apex corners of the outer frame, and the other end of the auxiliary support rod is fixedly connected to the fixed rod to form a triangular support structure.

[0012] Compared with the prior art, the present invention has the following advantages: This invention, by setting a measuring rod with a graduated scale on its surface, allows workers to visually observe the distance between the concrete surface and the opening. Furthermore, by incorporating a sampling square tube into the measuring plate, workers can determine whether the plate floats on the mud-water surface or the concrete surface, reducing errors caused by the mud-water surface during concrete pouring and preventing subsequent pile defects.

[0015] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper side", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figure 1 and 2 As shown, a concrete liquid level measuring device for bored piles includes a base assembly 1 and a measuring assembly 2. The base assembly 1 includes a base body 3 and a supporting rod 4. The supporting rod 4 is fixed to the top of the base body 3 and extends outward in a horizontal direction. A sliding sleeve that mates with the measuring assembly 2 is fixed to the outer end of the supporting rod 4. The top of the measuring assembly 2 slides in conjunction with the sliding sleeve, allowing it to slide freely in a vertical direction, and the height of the concrete liquid level in the pile pit is measured through a detection end at its bottom.

[0018] Specifically, such as Figure 1 and 3 As shown, the measuring component 2 includes a measuring rod 5 and a liquid measuring plate 6 fixed to the bottom of the measuring rod 5. The measuring rod 5 slides in conjunction with a sliding sleeve, allowing it to move freely in the vertical direction. A graduated scale is provided on the outer side of the measuring rod 5, allowing workers to visually observe the length of the measuring rod 5 extending into the pile pit. The liquid measuring plate 6 is welded and fixed to the bottom of the measuring rod 5, and multiple weight blocks 12 are fixed to its top surface to ensure that the liquid measuring plate 6 is in close contact with the top liquid surface of the concrete, avoiding errors in the measured concrete pouring depth due to the influence of the mud and water layer on the concrete.

[0019] Furthermore, a sampling square tube 7 is welded and fixed to the top surface of the liquid measuring plate 6. Workers press down on the measuring rod 5, causing the liquid measuring plate 6 to sink a certain distance. Simultaneously, surrounding concrete or muddy water will enter the sampling square tube 7. Then, workers pull up the measuring rod 5 until the liquid measuring plate 6 at the bottom of the measuring rod 5 detaches from the pile pit. By observing whether the sample taken from the sampling square tube 7 is concrete or muddy water, they can determine whether the liquid measuring plate 6 floats on the concrete or muddy water surface during measurement. This reduces the error caused by the muddy water surface during concrete pouring and avoids subsequent pile defects.

[0020] Furthermore, a horizontally positioned limiting rod 8 is fixed to the top of the measuring rod 5, which, in conjunction with the sliding sleeve, limits the extreme position of the measuring rod 5's descent when it descends.

[0021] like Figure 1 and 4 As shown, the base body 3 includes an upper fixing rod 9 and a lower triangular support 10. The top end of the fixing rod 9 is welded and fixed to the inner end of the supporting connecting rod 4. The triangular support 10 includes an outer frame and a connector 11 fixed at the center of the outer frame. The bottom of the fixing rod 9 is welded and fixed to the connector 11.

[0022] In this embodiment, the outer frame has a triangular structure. The connector 11 is made of angle steel.

[0023] Furthermore, an auxiliary support rod is fixed at each of the three top corners of the outer frame. The other end of the auxiliary support rod is fixedly connected to the fixed rod 9, which can form a triangular support structure on the fixed rod 9 to ensure the stability of the triangular support 10.

[0024] The working principle of this utility model is as follows: During the concrete pouring process, after the workers initially pour some concrete into the pile pit, they insert measuring rod 5 into the pit until the liquid level plate 6 at the bottom of the measuring rod 5 contacts the top of the poured concrete. The workers continue pouring concrete into the pit. The liquid level plate 6 gradually floats upwards due to the buoyancy of the concrete. The workers then use the scale on the measuring rod 5 to determine the distance between the concrete level and the opening.

[0025] When the poured concrete reaches the required height, the worker lowers the measuring rod 5, causing the measuring plate 6 to sink a certain distance. Surrounding concrete or muddy water will then enter the sampling tube 7. The worker then pulls the measuring rod 5 upwards until the measuring plate 6 at the bottom of the rod 5 detaches from the pile pit. The sample taken from the sampling tube 7 is then observed to determine whether it is concrete or muddy water. If concrete enters the sampling tube 7, the concrete pouring is complete.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
