[0019] Please see Figures 1-4One embodiment provided by this utility model:

[0020] Anti-collapse protection device for underground pipelines in silty sand soil: including underground pipeline 14, the outer surface of underground pipeline 14 is covered with protective cover 6, the bottom of protective cover 6 is provided with support base 1, anti-collapse plate 3 is fixedly connected to the surface of support base 1, telescopic rod 7 is provided on the surface of support base 1, protective plate 2 is provided on the surface of telescopic rod 7, arc-shaped protective frame 4 is provided on the top of protective plate 2, first protective frame 8 is fixedly connected to the surface of protective plate 2, second protective frame 9 is fixedly connected to the bottom of protective plate 2, the end of second protective frame 9 away from protective plate 2 is fixedly connected to the surface of support base 1, a set of rubber protrusions 13 are provided at the bottom and top of telescopic rod 7, and a rectangular groove 5 is opened at the bottom of support base 1.

[0021] Furthermore, the protective cover 6 includes a metal cover 10 and a restraint cover 11. The space between the metal cover 10 and the restraint cover 11 is a vacuum state, which can effectively keep the hot liquid warm. The restraint cover 11 can suppress the thermal expansion of the pipeline. A moisture-proof layer 12 is provided between the restraint cover 11 and the underground pipeline 14. The moisture-proof layer 12 reduces the damage of moisture to the underground pipeline 14.

[0022] Furthermore, the support base 1 is provided with multiple sets, and two sets of anti-collapse plates 3 are provided on each set of support base 1. The two sets of anti-collapse plates 3 are symmetrically distributed on both sides of the support base 1. The anti-collapse plates 3 can prevent the collapse of the side soil from damaging the device, and the support base 1 can also effectively buffer the impact force of the side soil on the device.

[0023] Furthermore, multiple sets of rectangular grooves 5 are provided, and the rectangular grooves 5 are arranged linearly and evenly on the bottom of the support base 1. The rectangular grooves 5 can increase the contact area with the ground, making the device more stable.

[0024] Furthermore, the outer surface of the telescopic pole 7 is wrapped with a moisture-proof cover to prevent the telescopic pole 7 from getting damp and corroded, thus extending the service life of the telescopic pole 7.

[0025] Furthermore, the rubber protrusion 13 at the top of the telescopic rod 7 is fixedly connected to the bottom of the protective plate 2, and the rubber protrusion 13 at the bottom of the telescopic rod 7 is fixedly connected to the surface of the support base 1. The rubber protrusion 13 plays a shock-absorbing role on the telescopic rod 7.

[0026] Furthermore, the second protective frame 9 is tilted, and the support base 1 supports the protective plate 2 through the second protective frame 9. The first protective frame 8 and the second protective frame 9 improve the stability of the protective plate 2.

[0027] Working principle: In the event of soil collapse above the underground pipeline 14, the support base 1 bears the weight of the pipeline and the protective plate 2, and can also withstand the impact force of the trench slope collapse on the device. The arc-shaped protective frame 4 at the top of the protective plate 2 can bear more concentrated stress and distribute more load to the protective plate 2. The rectangular groove 5 below the support base 1 increases the contact area between the device and the ground, and improves the stability of the device under load. In the event of soil collapse on the side of the underground pipeline 14, the anti-collapse plate 3 can effectively resist the soil collapse caused by the slope effect of the trench and prevent the damage of the telescopic rod 7 by the frost heave of the soil. The telescopic rod 7 is used to support the protective plate 2, and the rubber protrusions 13 on it can play a shock absorption role and further protect the telescopic rod 7.

[0028] The outer layer of the pipeline is equipped with a constraint cover 11, and the outer layer is wrapped with a metal cover 10. The remaining space between the metal cover 10 and the constraint cover 11 is in a near-vacuum state. This can not only constrain the deformation and damage of the underground pipeline 14, but also reduce heat loss during transportation. At the same time, the outer wall of the metal cover 10 and the outer wall of the underground pipeline 14 have a moisture-proof layer 12, which reduces the damage to the pipeline caused by moisture. Furthermore, the design of the metal cover 10 and the constraint cover 11 in the protective cover 6 effectively insulates the heat and reduces the heat loss of the hot liquid.
