Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of concrete testing, and in particular relates to a concrete pumping loss testing device. Background Art
[0002] As an advanced concrete construction technology developed along with the progress of science and technology, concrete pumping technology has now become an important technical means in construction and plays an important role in engineering construction. Concrete pumping refers to the process of transporting and pouring concrete through concrete pumps and conveying pipelines. It is currently the most efficient and widely used method of on-site concrete transportation. Whether the on-site transportation and pouring of concrete are continuous and effective is crucial to ensuring construction quality and improving economic benefits. Pumping construction can achieve continuous transportation and pouring of concrete in one go. Compared with the concrete transportation methods such as wheelbarrows, dump trucks, and cranes used in traditional concrete projects, it has many advantages such as high efficiency, low cost, and labor savings. It can also greatly improve the efficiency of on-site concrete pouring, and effectively solves the problem of vertical transportation of concrete in high-rise and super-high-rise building construction.
[0003] During concrete pumping, excessive slump loss often occurs. Sometimes, the concrete enters the pump with a high slump and excellent fluidity, but becomes dry and hard upon exiting the pump. Therefore, predicting significant concrete pumping loss has become particularly important and crucial. Currently, there are no relevant testing standards for concrete pumping loss. Therefore, it is crucial to develop a rapid detection device for concrete pumping loss that can quickly and intuitively measure concrete pumping performance to meet the needs of future concrete development.

[0029] Reference Figure 1An embodiment of the utility model provides a concrete pumping loss testing device, which includes a base 1, a first container 2, a press 3, a second container 4 and a detection container 5.
[0030] The first container 2 is placed on the pedestal 1. A first valve 21 is provided at the bottom of the first container 2 to connect the inside and outside of the first container 2. The first container 2 is used to inject concrete to be tested. When the first valve 21 is opened, concrete can flow out of the first valve 21.
[0031] The press 3 is placed on the pedestal 1. A pressing portion 22 is provided at the end of the pressing lift end 21 of the press 3, adapted to the inner wall of the first container 2. The pressing portion 22 can extend into the first container 2 after being lowered. A sealing portion 23 is provided around the pressing portion 22, which abuts against the inner wall of the first container 2 via the sealing portion 23. The press 3 can apply pressure to the concrete in the first container 2 to simulate a concrete pumping scenario.
[0032] The press 3 is conventional, such as a pneumatic press or a hydraulic press.
[0033] One end of the second container 4 is connected to the first valve 21, and the other end of the second container 4 has a container opening. Concrete flowing out of the first container 2 through the first valve 21 flows out through the second container 4, so that the concrete has a certain flow distance.
[0034] The top surface of the inspection container 5 has a feed port, which is located below the container opening. The top surface of the inspection container 5 is preferably an open structure to better check whether the inspection container 5 is filled or to check the shape of the concrete injected into the inspection container 5.
[0035] During use, the concrete to be tested is poured into the first container 2. After a first preset pressure is applied to the concrete in the first container 2 by the press 3, the first valve 21 is opened. A second preset pressure is then applied, where the second preset pressure is less than the first preset pressure. Under the pressure, the concrete in the first container 2 flows through the first valve 21 and the second container 4, respectively, before flowing into the test container 5. The concrete's flow properties are tested by measuring how long it takes for the concrete to fill the test container.
[0036] In some embodiments, the top surface of the first container 2 is an open structure.
[0037] In some embodiments, the top surface of the first container 2 has a top surface opening, and the pressing and lifting end 21 of the press 3 passes through the top surface opening.
[0038] In some embodiments, a base 6 is provided on the stand 1 , the first container 2 is placed on the base 6 , and the detection container 5 is located on the side of the base 6 .
[0039] The first container 2 can be raised by the base 6 , so that the detection container 5 can receive the concrete flowing out of the second container 4 .
[0040] In some embodiments, the first container 2 is a cylindrical container, and the pressing portion 22 is a circular pressing portion 22 .
[0041] In some embodiments, the pressing portion 22 is a pressing plate.
[0042] The lower pressing plate is preferably a stainless steel lower pressing plate.
[0043] In some embodiments, the sealing portion 23 is a rubber ring that is fixed to the periphery of the pressing portion 22 .
[0044] In some embodiments, the detection container 5 is a transparent container.
[0045] The detection container 5 can be a transparent container made of acrylic material. The transparent container can facilitate the user to observe whether the detection container 5 is filled with concrete.
[0046] In some embodiments, reference Figure 2 The concrete pumping loss test device also includes a detection funnel 7, which is located between the container opening and the detection container 5. The upper inlet of the detection funnel 7 is located below the container opening. The lower outlet of the detection funnel 7 is provided with a second valve 71, which is located above the feed port of the detection container 5.
[0047] In this embodiment, the concrete flowing out of the second container 4 does not flow directly into the detection container 5 , but first flows into the detection funnel 7 .
[0048] During use of this embodiment, the concrete to be tested is poured into the first container 2. After a first preset pressure is applied to the concrete in the first container 2 by the press 3, the first valve 21 is opened and the second valve 71 is closed. A second preset pressure is then applied, where the second preset pressure is less than the first preset pressure. Under the pressure, the concrete in the first container 2 passes through the first valve 21 and the second container 4, respectively, and flows into the test funnel 7. When the test funnel 7 is filled with concrete, the press 3 stops applying pressure. The second valve 71 is opened, and the concrete flow properties are tested by measuring the time it takes for the concrete in the test funnel 7 to flow out.
[0049] While this design of this embodiment may increase testing time and be slightly more cumbersome than not including a test funnel 7, it better aligns with the pumping simulation scenario, resulting in a more accurate test of the concrete's flow properties. Furthermore, in this embodiment, the volume of the test funnel 7 is typically smaller than that of the test container 5. Therefore, when the test funnel 7 is empty, the test container 5 is typically not completely filled. In this case, the user can further determine the concrete's flowability by observing the shape of the concrete within the test container 5.
[0050] In some embodiments, the second container 4 is a trough-type container.
[0051] In this case, the second container 4 may be a non-enclosed channel steel structure.
[0052] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. A person skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the present invention shall be protected within the scope of the appended claims.
