Problems solved by technology
[0002] At present, indoor tests on landslides are usually limited to two-dimensional simulations. The test equipment and instruments used in such tests are relatively simple and easy to control, and the results obtained have a certain gap with the actual situation.
In order to better simulate the failure mechanism of landslides under the action of rainfall and reservoir water, a large-scale three-dimensional landslide physical model test platform came into being; The quality of sealing is directly related to the accuracy of test results and test efficiency

Embodiment Construction
[0019] like Figure 1~Figure 5 Shown, a kind of airtight door that is used for landslide physics test model, comprises door frame 1, is characterized in that, described door frame 1 is provided with raised edge 4 around, and described door frame 1 is equipped with door shaft 9, and door shaft 9 connects door panel 2. The door panel 2 is provided with an outer frame 10 and an inner frame 11, and a strip-shaped sealing tape 3 is embedded between the outer frame 10 and the inner frame 11. The door panel 2 is provided with a plurality of lattice strips 12 , and the ends of the lattice strips 12 are connected to the inner frame 11 . The door frame 1 is equipped with a platform.
[0020] The settlement support is installed on the door panel 2 through the rotating shaft 13, and the platform 7 is installed on the door frame 1. Since the entire airtight door has a large area and is made of steel, the airtight door has a high quality. It is inevitable that problems such as deformatio...

The invention provides a sealing door for a landslip physical test model. The sealing door comprises a door frame, wherein a convex edge is arranged on the periphery of the door frame; the door frame is provided with a door shaft; the door shaft is connected with a door plate; an outer edge frame and an inner edge frame are arranged on the door plate; and a strip-shaped sealing belt is embedded between the outer edge frame and the inner edge frame. According to the sealing door for the landslip physical test model, a pressing plate on the door plate is extruded by a bolt; and the convex edge on the door frame is contacted and extruded with the strip-shaped sealing belt embedded between the outer edge frame and the inner edge frame of the door plate, so as to form the sealing performance to prevent rainwater and stored water from flowing out.
Description
technical field [0001] The invention relates to a hermetic door, in particular to a hermetic door used for a physical test model of a landslide. Background technique [0002] At present, indoor landslide tests are usually limited to two-dimensional simulations. The test equipment and instruments used in this type of test are relatively simple and easy to control. The results obtained have a certain gap with the actual situation. In order to better simulate the failure mechanism of landslides under the action of rainfall and reservoir water, a large-scale three-dimensional landslide physical model test platform came into being; The quality of the tightness is directly related to the accuracy of the test results and the test efficiency. Therefore, seeking a door with good sealing performance to rainwater and reservoir water and convenient operation is a technical problem to be solved at present. Contents of the invention [0003] The purpose of the present invention is to ...
