[0001] The present invention relates to the technical field of simulation demonstration, in particular to a simulation demonstration device for road surface settlement caused by underground pipeline damage. Background Art

[0002] At present, the laying of underground pipelines is one of the important projects in modern urban construction. Underground pipelines refer to pipelines and their ancillary facilities such as water supply, drainage, gas, heat, electricity, communications, radio and television, and industry within the city. They are important infrastructure and "lifelines" to ensure the operation of the city. At present, major cities have gradually improved the urban underground pipeline system, so that the construction and management level of underground pipelines can adapt to the needs of economic and social development, and the emergency disaster prevention capabilities have been greatly improved.

[0003] After long-term use, underground pipelines are easily eroded by soil and sewage, causing corrosion in some parts. In severe cases, they will be damaged. After the underground pipelines are damaged, soil will fall in from the broken parts, causing settlement and collapse of the foundation and road surface.

[0031] like Figure 1-9As shown, a road surface settlement simulation demonstration device caused by underground pipeline damage includes a demonstration box 1, a demonstration pipe 2, a push cylinder 8, and a push rod 9. A partition 22 is fixed in the demonstration box 1, and a demonstration bin 3 is formed on the upper part of the partition 22. The demonstration pipe 2 is arranged in the demonstration bin 3, and both ends of the demonstration pipe 2 pass through the outer walls of the demonstration box 1 on both sides.

A clamping mechanism is provided in the push cylinder 8. The clamping mechanism can clamp the push cylinder 8 and the arc-shaped slide 14 and drive the arc-shaped slide 14 to rotate and slide along the inner wall of the demonstration pipe 2, so that the road surface settlement caused by the damage of the underground pipeline can be observed intuitively.

[0032] Observation windows are provided on the upper parts of both sides of the demonstration box 1, and glass plates 4 are provided in the observation windows to facilitate external observation.

A screw rod 19 is provided for rotation in the installation bin, and the screw rod 19 passes through the two sliders 20 and is threadedly connected thereto. A motor 13 is bolted to the outer wall of one side of the demonstration box 1. The motor 13 is used to drive the screw rod 19 to rotate. Support rods 18 are hinged on the sliders 20. A vertical rod 17 is fixed to the bottom of the demonstration pipe 2, and the lower end of the vertical rod 17 passes through the partition 22 and is slidably connected thereto. The upper ends of the two support rods 18 are hinged to the lower ends of the vertical rods 17. After the motor 13 is started, the demonstration pipe 2 can be driven to rise and fall through the screw rod 19, the slider 20, and the support rod 18 to adjust to the specified simulation demonstration height. A plurality of guide telescopic rods 21 are fixed to the bottom wall of the installation bin, and the upper ends of the guide telescopic rods 21 pass through the partition 22 and are fixed to the bottom of the demonstration pipe 2.

[0040] Working principle: When in use, the motor 13 can be turned on, and the demonstration pipe 2 can be driven to rise and fall through the screw rod 19, the slider 20, and the support rod 18. After adjusting to the specified simulation demonstration height, the demonstration chamber 3 is filled with simulated soil and simulated roadbed, so that the demonstration pipe 2 is buried. When simulating the wear of the underground pipeline, the push rod 9 is held to insert the push cylinder 8 from one end of the demonstration pipe 2 and insert it into the corresponding arc-shaped slide plate 14. The inner rod 24 is rotated to trigger the latch 26 through the connecting block 31 and the connecting rod 30, and then the push cylinder 8 is rotated so that the latch 26 is inserted into the slot 32, so that the push cylinder 8 is relatively fixedly connected to one of the curved slides 14, and the push rod 9 is rotated so that the push cylinder 8 drives the curved slide 14 to slide along the inner wall of the demonstration pipe 2, opening the corresponding simulated rupture 15, and then the push cylinder 8 is taken out. At this time, the simulated soil and simulated roadbed settlement after the demonstration pipe 2 is damaged are observed. After the demonstration is completed, the push cylinder 8 can be used to push out the soil that has fallen into the demonstration pipe 2, close the curved slide 14 and push out the soil that has fallen into the demonstration pipe 2, and the push cylinder 8 can be used to close the simulated rupture 15 as described above, and it can be reused.
