[0035] The present application provides a simulation of composite landslides zoned segmented sliding surge test device, the simulation of composite landslides zoned segmented sliding surge test device is set by setting landslide body form simulation device 4 on the belt conveyor 3, with the help of landslide body form simulation device 4 simulation of composite landslides zoned segmented sliding, while supplemented by belt conveyor 3 control composite landslides zoned segmented sliding speed, so that the zoned segmented landslide body on the belt conveyor 3 enters water at a set speed, so as to realize the precise simulation of the surge characteristics of composite landslides zoned segmented sliding, and provide sufficient real data support for accurate research and judgment of the surge characteristics of composite landslides.

[0036] Specifically, in one embodiment of the application, as Figure 1As shown, the surge test device for simulating the sectional and segmented descent of a composite landslide includes a belt conveyor 3 and a landslide body morphology simulation device 4 arranged above the belt conveyor 3. The landslide body morphology simulation device 4 has a plurality of partition compartments 14. Each partition compartment 14 can independently put any amount of landslide body test material 18 onto the belt conveyor 3, so as to realize the sectional and segmented descent of the simulated composite landslide. After the landslide body test material 18 falls onto the belt conveyor 3, the downward moving speed of the landslide body test material 18 is adjusted with the help of the belt conveyor 3, so that the landslide body test material 18 enters the water at a set speed, accurately simulating the surge characteristics of the sectional and segmented descent of the composite landslide, and providing sufficient and real data support for accurate research and judgment of the surge characteristics of the composite landslide.

[0037] In this embodiment, the landslide body morphology simulation device 4 includes a plurality of partitions 17 arranged horizontally and vertically, such as Figure 5 As shown, there are 5 transversely arranged and 6 longitudinally arranged partitions 17, and a plurality of transversely arranged partitions 17 are intersected and fixedly connected with a plurality of longitudinally arranged partitions 17, thereby defining a plurality of partition compartments 14. The partitions 17 are used to divide the landslide body. The size of the landslide body in different partition compartments 14 can be adjusted according to the actual simulation needs. The partition compartments 14 are independent of each other and do not interfere with each other. A feeding door 16 is provided at the bottom of each partition compartment 14. When the feeding door 16 is opened, the test material 18 in the partition compartment 14 falls onto the belt conveyor 3 below it and is transported through the partition. The feeding doors 16 of different partitioned compartments 14 are opened in different time periods to enable the test materials 18 in different partitioned compartments 14 to be dropped onto the belt conveyor 3 in different zones and at different time periods, thereby simulating the zoned and segmented descent of the compound landslide. The sliding speed of the test materials 18 falling onto the belt conveyor 3 from different partitioned compartments 14 can be adjusted to a set value with the help of the belt conveyor 3, so that the zoned and segmented landslide bodies on the belt conveyor 3 enter the water at the set speed, thereby accurately simulating the surge characteristics of the zoned and segmented descent of the compound landslide, and providing sufficient and real data support for accurate research and judgment of the surge characteristics of the compound landslide.

[0038] In this embodiment, the feeding door 16 under each partition compartment 14 is independently controlled. The feeding door 16 can be opened manually or an automatic door can be used for easy operation. Each automatic door is independent of each other and can be controlled independently. By remotely controlling the different release times of the automatic doors, the simulation of the landslide sliding in sections can be achieved.

[0039] In this embodiment, the partition 17 is fixed to the upper end of the connecting rod 15, and the lower end of the connecting rod 15 is fixedly connected to the belt conveyor 3. Figure 1As shown, there is enough space between the partition 17 and the belt conveyor 3 for the test material 18 in the partition compartment 14 to quickly fall onto the belt conveyor 3, while preventing the feeding door 16 from being unable to fully open due to the insufficient distance between the conveyor belt 12 and the partition compartment 14, thereby hindering the falling of the landslide body.

[0040] Further, such as Figure 5 As shown, in order to prevent the feeding door 16 from affecting the test material 18 in the partition compartment 14 from falling quickly onto the belt conveyor 3 after it is opened, the length direction of the feeding door 16 is parallel to the length direction of the belt conveyor 3. In this design, the opening direction of the feeding door 16 is perpendicular to the conveyor belt 12, which minimizes the obstruction of the opened feeding door 16 to the landslide.

[0041] In this embodiment, if Figure 4 As shown, the belt conveyor 3 includes a mounting frame 13 and rollers rotatably mounted on the mounting frame 13, the rollers are tightly wrapped around the conveyor belt 12, the rollers include active rollers 11 and driven rollers 10, and a plurality of partition compartments 14 are located directly above the conveyor belt 12; Figure 1 As shown, the lower end of the connecting rod 15 is fixedly connected to the mounting bracket 13 .

[0042] Furthermore, in this embodiment, Figure 1 As shown, the surge test device for simulating the sectional and segmented sliding of a composite landslide also includes a slope inclination control device 2. The belt conveyor 3 is arranged on the slope inclination control device 2. The slope inclination control device 2 is used to adjust the inclination angle of the conveyor belt 12 of the belt conveyor 3 so that the sectional and segmented landslide bodies on the belt conveyor 3 enter the water at a set angle, thereby meeting the simulation experiments under various complex landslide entry conditions and providing technical support for the simulation research of landslide secondary surge disasters.

[0043] Specifically, in this embodiment, Figure 1 As shown, the slope angle control device 2 includes a plurality of hydraulic support rods 9 distributed along the length direction of the belt conveyor 3. The upper end of the hydraulic support rod 9 is hinged to the mounting frame 13. The inclination angle of the conveyor belt 12, that is, the angle of the landslide body entering the water, is adjusted by controlling the extension amount of the plurality of hydraulic support rods 9. Preferably, as Figure 3 As shown, the upper end of the hydraulic support rod 9 is hinged to the mounting frame 13 through the top rotating wheel 7.

[0044] In this embodiment, the hydraulic support rod 9 may also be replaced by a cylinder or a linear motor.

[0045] Furthermore, Figures 1-2As shown, the lower end of the hydraulic support rod 9 is hinged with the support truss 1 through the bottom rotating wheel 8, which is designed to facilitate the swing adjustment of the hydraulic support rod 9 on the support truss 1 to adjust the inclination angle of the belt conveyor 12, the bottom of the support truss 1 is provided with wheels 5 to facilitate the movement of the support truss 1, the support truss 1 can support the landslide body shape simulation device 4, the slope angle control device 2 and the belt conveyor 3 on one hand, and the bottom wheels 5 are used to push the simulated composite landslide zoned and segmented sliding surge test device to move on the other hand, so as to change the relative position of the simulated composite landslide zoned and segmented sliding surge test device and the river channel, thereby meeting the simulation requirements of different sliding positions.

[0046] In the embodiment, as shown in the drawings, Figure 6 The lower end of the belt conveyor 3 is provided with a simulated river channel, and the zoned and segmented landslide body on the belt conveyor 3 enters the simulated river channel to simulate the surge test at a set angle and speed, of course, in other embodiments, the simulated composite landslide zoned and segmented sliding surge test device of the embodiment can be directly moved to the river bank in the outdoor natural environment to simulate the surge test.

[0047] In the embodiment, the simulated river channel is assembled by river channel components 19, which is designed to be simple, convenient and fast to disassemble and assemble, the river channel components 19 are prefabricated and can be assembled on the test site, and if a single component is damaged, only the single river channel component 19 needs to be replaced, thereby improving the test efficiency and reducing the cost.

[0048] In addition, the application also provides a simulated composite landslide zoned and segmented sliding surge test method, which comprises the following steps:

[0049] S1, filling test materials 18 into each partition compartment 14, and each partition compartment 14 can be filled with any amount of test materials 18, and the amount of the test materials 18 can be determined according to the specific simulation test conditions, and in general, the amount of the test materials 18 in different partition compartments 14 is different, and the distribution of the landslide body shape in the real state is simulated by placing different amounts of test materials 18 in the partition compartments 14;

[0050] S2, starting the belt conveyor 3;

[0051] S3, opening the feeding door 16 below different partition compartments 14 according to the needs, and the test materials 18 in the partition compartment 14 fall to the belt conveyor 3, and the feeding door 16 can be set as an automatic door for easy opening and closing;

[0052] S4, adjusting the downward moving speed of the test materials 18 on the belt conveyor 3 to a set speed to fully meet the simulation test requirements;

[0053] S5, the test material 18 enters water at a set speed, and then surge information is collected, thereby providing technical support for landslide secondary surge disaster simulation research.

[0054] In the embodiment, before S2, the belt conveyor 3 is started, the inclination angle of the conveying belt 12 of the belt conveyor 3 is adjusted, so that the test material 18 can enter water at a set angle, thereby fully meeting the requirements of simulation experiments, and the adjustment of the inclination angle of the conveying belt 12 of the belt conveyor 3 can be completed by the slope inclination control device 2.
