[0019] The utility model is now described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.
[0020] Please refer to Figure 1-5 A portable multifunctional sprayed concrete test bench comprises a tunnel 1 and a test bench body 2. The test bench body 2 comprises a vertically supported I-beam 21 and a walkway plate above. The I-beam 21 is welded and fixed to the walkway plate. Reinforced legs 211 are provided on both sides of the bottom of the I-beam 21 to increase the support stability. A sprayed concrete test assembly is provided on the bottom surface of the walkway plate.
[0021] In this embodiment, when doing the concrete spraying anchor test, the test bench body 2 is arranged outside the tunnel. During the test, the test bench body 2 is fixed, and then the concrete is sprayed on the test component by the spraying anchor trolley, and the connection and tightness between the concrete and the test component are observed, so as to judge the effect of the concrete spraying on the inner wall of the tunnel; because the concrete is sprayed on the bottom surface of the test component, the test component is simulated as the inner wall of the tunnel, thereby increasing the simulation authenticity. At the same time, the simulated spraying test can practice the spraying anchor operation in advance, so as to improve the spraying anchor quality and spraying speed.
[0022] After the concrete shotcrete experiment is completed, the test bench body 2 can also be arranged inside the tunnel. When inside the tunnel 1, the walkway plate is used to support the workers so that the workers can perform construction on the inner wall of the tunnel.
[0023] A space is reserved below the test bench body 2 for vehicles 6 to pass through, so that the vehicles can load and unload building materials.
[0024] In addition, the inner wall of the tunnel 1 is provided with a wind duct 3, a water inlet pipe 4 and a drainage pipe 5, which are laid along the inner wall trajectory of the tunnel 1. The wind duct 3 provides fresh air for the heading face and removes harmful gases by drilling and blasting the tunnel; the water inlet pipe 4 provides construction water for the double-arm drill to ensure civilized construction in the tunnel, and the drainage pipe pumps sewage from the working face out of the tunnel to ensure the cleanliness of the heading face.
[0025] Specifically, the walkway board includes a lower walkway board 22 , a middle walkway board 23 and an upper walkway board 24 , and the test assembly is arranged on the bottom surface of the middle walkway board 23 .
[0026] The test assembly includes two U-shaped fixing plates 7 set opposite to each other, a partition 71 is provided in the opening of the U-shaped fixing plate 7, an upper slider 72 is provided above the partition 71, and a lower slider 73 is provided below the partition 71, a slide plate 721 is provided between the two upper sliders 72, through holes 722 are evenly provided on the slide plate 721, and a plurality of steel bar shafts 731 are provided between the two lower sliders 73.
[0027] The slide plate 721 and the steel bar shaft 731 can move horizontally along the U-shaped fixing plate 7 , and the slide plate 721 partially overlaps with the steel bar shaft 731 .
[0028] During the spray anchor test, the concrete can be sprayed directly onto the slide plate 721, onto the steel bar shaft 731, or onto the overlapping portion of the slide plate 721 and the steel bar shaft 731; that is, the spray anchor test has three test methods, and the degree of concrete adhesion and solidification can be determined through a variety of test methods to increase the test simulation effect.
[0029] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
