Technical Field

[0002] In hydraulic model tests, in order to simulate the dynamic bed and slope scour problems in actual projects, it is often necessary to set up hinged block stone protection structures. Traditional methods mostly use sandbags or wire cages to bundle sand for simulation, but this method is significantly different from the actual hinged block stone in structure and performance, and cannot ensure the similarity criteria of hydraulic model tests, thus affecting the accuracy and reliability of the test results.

[0003] Another traditional method is to drill holes directly in the sandstone and then connect them by threading to simulate the hinge effect. However, this method is not only difficult to make, but also has safety hazards during the drilling process. It is also difficult to implement quickly and safely, which greatly limits its application in hydraulic model tests. Summary of the invention

[0007] The transverse plate is provided with a plurality of first hinge grooves, and the longitudinal plate is provided with a plurality of second hinge grooves, and the hinge grooves are used to set hinges;

[0008] The transverse plate and the longitudinal plate are cross-nested through the joint seams to form a frame-shaped mold with a plurality of sashes.

[0009] Preferably, the first hinge groove and the first connecting seam are arranged on two opposite sides of the transverse plate and are staggered.

[0010] Preferably, the second hinge groove and the second connecting seam are arranged on the same side of the longitudinal plate;

[0011] Each of the second hinge grooves is arranged between two adjacent second connecting seams.

[0012] Preferably, an arc-shaped buckle is provided at one end of the hinge slot away from the opening;

[0013] The arc-shaped buckle is used for clamping the hinge.

[0014] Preferably, it also includes a bottom plate;

[0015] The bottom plate is provided on one side surface of the frame-shaped mold.

[0016] Preferably, the length of the first connecting seam accounts for a first preset proportion of the width of the transverse plate.

[0017] Preferably, the length of the second connecting seam accounts for a second preset proportion of the width of the longitudinal plate;

[0018] The sum of the first preset ratio and the second preset ratio is 1.

[0020] Preferably, it also includes a hardening-promoting device;

[0021] The hardening accelerating device is arranged on a side of the base plate away from the frame-shaped mold.

[0022] Beneficial effects: The utility model greatly reduces manual operations and improves construction efficiency through rapid prototyping molds, thereby shortening the model construction cycle and reducing labor costs. Secondly, the hinge structure and block stone casting method are used to make the structural characteristics of the test device more similar to the actual situation, effectively ensuring the similarity criteria of the hydraulic model test, thereby improving the reliability and accuracy of the test results.
