A bedding landslide test device

Abstract

This invention discloses a bedding-parallel landslide testing device, comprising a sliding panel, two retaining glass panels, a retaining box, a loading trolley, a loading chamber, a loading baffle, a retaining structure, and a laser rangefinder. In the laboratory simulation phase, various retaining structures can be used to simulate the macroscopic stress performance of different retaining structures during a bedding-parallel landslide, providing a reference for construction design. The retaining box contains a laser rangefinder to detect the displacement of the retaining structure during a simulated bedding-parallel landslide, determining whether the retaining structure is functioning or has failed. The retaining glass panels are rotatably connected to the retaining box, thus the angle of the sliding panel is adjustable, enabling the simulation of bedding-parallel landslides at different slopes and the displacement of the retaining structure under different slope influences. The loading trolley can carry multiple levels of loading weights, which can be used to simulate the destructive effects of bedding-parallel landslides under different loads on the retaining structure.

Description

[0002] In recent years, with the increasing occurrence of extreme weather events, bedding-parallel landslides have occurred repeatedly, posing a significant threat to people's lives and property and engineering construction. During the construction of the Chengdu-Kunming Railway in the 1950s-1970s, large-section anti-slide piles were successfully applied for the first time, followed by the development of composite anti-slide retaining structures such as gate-type rigid frame piles and H-type chair piles. Since the 21st century, new structures such as micro-composite piles and trenchless anti-slide piles have emerged, improving construction efficiency. Different types of retaining structures are needed for different types of bedding-parallel landslides to meet actual engineering requirements, and indoor tests can provide valuable reference for practical design. Currently, there is no experimental device specifically designed for bedding-parallel landslides.

[0043] like Figure 1-5 As shown, a bedding landslide testing device includes:

[0044] Slide panel 1;

[0045] Two retaining glass panels 4; the two retaining glass panels 4 are installed on both sides of the sliding panel 1;

[0046] Support box 5; The upper end of the support box 5 is open, the first end of the sliding panel 1 extends into the support box 5, and the two support glass 4 are rotatably connected to the two sides of the support box 5 through rotating bearings 10; the rotating bearings 10 can also be replaced by a rotating shaft.

[0047] Loading trolley 13; Loading trolley 13 is placed above the second end of sliding panel 1;

[0048] Loading box 11; A sliding sand filling area 2 is provided above the first end of the sliding panel 1, and sand is filled in the sliding sand filling area 2;

[0049] Loading baffle 12; Loading baffle 12 is placed between the sliding sand filling area 2 and the loading box 11, and the loading box 11 is placed on the sliding panel 1 and between the loading trolley 13 and the loading baffle 12;

[0051] A laser rangefinder 7 is used to monitor the displacement of the support structure 6 in real time. The laser rangefinder 7 is installed on the side of the support box 5 away from the sliding panel 1. The laser rangefinder 7 emits infrared rays to the support structure 6 to monitor its displacement in real time.

[0052] In this embodiment, the retaining glass and the retaining box are rotatably connected, so the angle of the sliding panel is adjustable, which can be used to simulate the occurrence of bedding landslides under different slopes, as well as the displacement of the retaining structure under the influence of different slopes. Sand and gravel are piled up in the sand-filled area 2 of the sliding surface to simulate the landslide area.

[0053] In some embodiments, such as Figure 1 and 2 As shown, a fixed slide rail 16 is installed above the second end of the sliding panel 1 along the length of the sliding panel 1, and the loading trolley 13 is guided and slidably placed on the fixed slide rail 16. The slide rail 16 is used to constrain the movement of the loading trolley 10 along a predetermined route.

[0054] In some embodiments, such as Figure 1 and 2 As shown, the bedding landslide test device also includes a support frame 17, a support gantry 18, and a mechanical hook 19. The first end of the support frame 17 is installed at the bottom of the support box 5, the support gantry 18 is installed on the second end of the support frame 17, and the mechanical hook 19 is installed on the top of the support gantry 18.

The support frame 17 employs a two-layer crossbar design to ensure stability and provide stable support for the support box 5. The mechanical hook 19 constrains the angle between the sliding panel 1 and the support box 5 at the start of the test or when the equipment is idle. During the simulation experiment, the angle between the sliding panel 1 and the support box 5 is adjusted via the hinge to simulate the changes in the support structure 6 when a bedding landslide occurs on a slope with different angles.

[0055] In some embodiments, the mechanical hook 19 can be an electric hoist to enable electric adjustment of the angle of the sliding panel 1.

[0056] In some embodiments, such as Figure 1 and 2As shown, the width of the loading baffle 12 is slightly smaller than the distance between the two retaining glass panels 4. This is designed to facilitate the isolation of the sand and gravel filled in the slip surface sand accumulation zone 2.

[0057] In some embodiments, such as Figure 3 As shown, the width of the support structure 6 is slightly smaller than the internal width of the support box 5.

[0058] In some embodiments, the loading box 11 is a hollow box structure, and the loading box 11 is filled with sand.

[0059] In some embodiments, such as Figure 4 As shown, a handle 21 is connected to the side of the loading box 11 facing the loading trolley 13 via two connecting rods 14. By pulling the handle 21, the loading box 11 can be pulled up along the sliding panel 1.

[0060] In some embodiments, such as Figure 3 As shown, the bottom of the support box 5 is provided with a support sand outlet 23, which is covered by a support sand outlet cover plate 9 when not in use. The height of the support sand filling zone 8 can be controlled by adding sand or opening the support sand outlet cover plate 9. The test sand and gravel are recovered from the support sand outlet 23 after the simulation test.

[0061] In some embodiments, such as Figure 4 As shown, a sand outlet 22 is provided on the sliding panel 1 below the sand-filling area 2. When not in use, the sand outlet 22 is covered by a sand outlet cover 3. The height of the sand-filling area 2 can be controlled by adding sand or opening the sand outlet cover 3. The sand outlet 22 is used to collect the test sand after the simulation test.

[0062] In some embodiments, such as Figure 1 and 2 As shown, the bedding landslide test apparatus also includes multiple loading weights 15; these multiple loading weights 15 are placed on the loading trolley 13. The loading weights 15 can be added according to actual needs.

[0063] In some embodiments, such as Figure 1 As shown, the normal of the retaining glass 4 is perpendicular to the sliding panel 1.

[0064] In some embodiments, the type of retaining structure 6 can be varied to simulate the macroscopic stress performance of different retaining structures when a bedding landslide occurs, which can provide a certain reference for construction design.

[0065] In some embodiments, the contact edge between the support box 5 and the sliding panel 1 is coupled by an adhesive tape to ensure that the sand and gravel in the sliding panel 1 can enter the support box 5 normally.

[0066] In some embodiments, such as Figure 5As shown, rollers are provided at the bottom of the loading box 11 to facilitate the movement of the loading box 11 on the sliding panel 1.

[0067] In some embodiments, such as Figure 5 As shown, a multi-level groove is provided on the loading trolley, and multiple loading weights are placed in the multi-level groove.

[0068] Working principle: During the simulation of a bedding landslide, sand is piled up in the sand-filled area 2 on the right side of the sliding panel 1 to the retaining structure 6. Sand-filled areas 8 are set up on both sides of the retaining structure 6, filled with sand and gravel as support. A loading box 11 is set on the left side of the sand-filled area 2. During the simulation of a bedding landslide, the loading box 11 is filled with sand and gravel to act as a load. A loading trolley 13 is set at the left end of the loading box 11, which can carry multiple levels of loading weights 15 to simulate a high-intensity bedding landslide. Sand and gravel are used to fill the sand-filled area 8 to simulate supporting soil. The angle of the sliding panel 1 is adjusted by rotating the bearing 10, thereby adjusting the angle between the sliding panel 1 and the retaining box 5. This is used to simulate the impact of bedding landslides at different angles on the retaining structure 6 and to determine whether the retaining structure 6 has failed.

[0069] When the loading trolley 13 slides, it causes the loading box 11 to slide simultaneously on the sliding panel 1. Pressure is applied to the sand-filled area 2 on the right side of the sliding panel 1 through the loading baffle 12, causing the sand and gravel in the sand-filled area 2 to move. Finally, the pressure is transmitted to the support structure 6, thus simulating a landslide along the bedding plane. The loading baffle 12 is in contact with the support glass 4. Through the combined action of the loading baffle 12 and the support glass 4, the sand and gravel in the sand-filled area 2 move in a straight line along the sliding panel 1 towards the support box 5. Finally, the force is transmitted to the support structure 6 and the support sand-filled area 8. The displacement of the support structure 6 is recorded by the laser rangefinder 7. The displacement is used to determine whether the support structure 6 has failed in this test condition.

[0070] The loading trolley 13 is equipped with multi-stage loading weights 15. When the weights 15 exert their own weight on the loading trolley 13, the combined weights of the loading trolley 13 and the loading weights 15 cause the loading trolley 13 to slide on the sliding panel 1. The sliding panel 1 is made of a smooth material. The loading trolley 13 contacts the sliding panel 1 through pulleys. The friction on the sliding panel 1 is negligible. The thrust on the sand-filled area 2 can be simplified to the component of the weights of the loading baffle 12, the loading box 11, the fixed bearing 14, the loading trolley 13, and the loading weights 15 mounted on the loading trolley 13 along the sliding panel.

[0071] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
