[0027] Reference Figure 1-4 The figure shows a preferred embodiment of the present invention.

[0028] The protective structure for urban environmental geological disasters is arranged at the foot of the slope 100. When the slope 100 slides, it reduces the impact of the landslide stones on the road surface and buffers the impact of the stones.

[0029] The protective structure for urban environmental geological disasters includes a blocking structure arranged at the foot of a slope 100 and a buffer ditch 200 arranged at the foot of the slope. The buffer ditch 200 extends along the length direction of the foot of the slope. The buffer ditch 200 is arranged between the slope 100 and the blocking structure, and a buffer belt 300 is provided between the buffer ditch 200 and the blocking structure. The buffer belt 300 is provided with a buffer structure for slowing down the rolling speed of landslide stones.

[0030] The blocking structure includes a fixing frame 400 fixed on the ground. The fixing frame 400 is provided with an elastically swinging blocking plate 402, which is arranged toward the slope 100. When the blocking plate 402 is impacted by a landslide of the slope 100, the blocking plate 402 automatically swings and adjusts its position according to the force.

[0031] The protective structure for urban environmental geological disasters provided above is arranged at the foot of the slope 100. When a landslide occurs, the soil of the landslide can enter the buffer ditch 200. The stones of the landslide are buffered by the buffer ditch 200 and the buffer belt 300, thereby reducing the impact speed. When the stones impact the blocking plate 402, the blocking plate 402 can automatically swing to adjust its position, buffering the impact force of the stones and preventing the stones from further rolling and impacting toward the road surface, thereby effectively playing a protective role.

[0032] Along the direction from top to bottom, the width of the buffer ditch 200 gradually decreases, which makes it easier for the landslide soil to enter the buffer ditch 200.

[0033] Water pipes 201 are provided on both sides of the buffer ditch 200. The water pipes 201 have multiple water spray nozzles, which are arranged at intervals along the axial direction of the water pipes 201. The water pipes 201 are buried in the soil, and the water spray nozzles of the water pipes 201 are arranged toward the buffer ditch 200 and are connected to the buffer ditch 200.

[0034] After the landslide soil is placed in the buffer ditch 200, water can be sprayed to make the landslide soil in the buffer ditch 200 form fluidized soil, and the soil can flow along the buffer ditch 200 to discharge the soil as quickly as possible.

[0035] The top of the buffer strip 300 is arched upward to form an arched portion, and the buffer structure includes an elastic rubber layer 301 covering the arched portion. When the landslide stone impacts downward, it is buffered by the arched portion, and in the process of rolling over the arched portion, the rubber layer 301 is squeezed and deformed, which can further buffer the landslide stone.

[0036] In this embodiment, the middle part of the arched portion is recessed downward to form a recessed groove 302 with an open top, and the adhesive layer 301 covers the top opening of the recessed groove 302. When the adhesive layer 301 is pressed, the adhesive layer 301 is deformed downward and embedded in the recessed groove 302. In this way, when the adhesive layer 301 sinks into the recessed groove 302, a concave structure is formed on the arched portion, which can buffer the landslide stones.

[0037] In this embodiment, a buffer plate 403 is provided on the fixed frame 400, the lower end of the buffer plate 403 is hinged to the fixed frame 400, and the upper end of the buffer plate 403 extends upward; a telescopic shaft 401 is connected between the buffer plate 403 and the fixed frame 400, and the buffer plate 403 and the fixed frame 400 are relatively fixedly arranged through the telescopic shaft 401; the telescopic shaft 401 has a certain telescopic ability, when the buffer plate 403 is impacted, it can be buffered by telescoping, and the inclination angle of the buffer plate 403 can be adjusted by adjusting the telescopic length of the telescopic shaft 401.

[0038] The buffer plate 403 has an open groove, and the open groove is arranged toward the slope 100; the blocking plate 402 has an embedded portion embedded in the open groove and an exposed portion exposed outside the open groove, and the embedded portion has an end surface facing the bottom of the open groove, and a swing interval 404 is formed between the end surface and the bottom of the open groove;

[0039] A hinge position 410 is provided in the middle of the end face, and the hinge position 410 is hingedly arranged with the center of the opening groove. Along the direction from the hinge position 410 to the periphery of the end face, the end face is inclined toward the slope 100; an elastic body 405 is provided in the swing interval 404, and the elastic body 405 is respectively connected to the end face and the bottom of the opening groove; when the blocking plate 402 is impacted by the landslide of the slope 100, the blocking plate 402 automatically swings and adjusts its position according to the force, with the hinge position 410 as the swing center.

[0040] When the blocking plate 402 is impacted, the blocking plate 402 is subjected to uneven force due to the different shapes of the landslide rocks. At this time, the elastic body 405 can be deformed to perform the first buffering, and the blocking plate 402 can swing around the hinge 410 as the center, automatically adjust the position, and perform the second buffering, which greatly enhances the buffering capacity. After the automatic adjustment of the position, the blocking plate 402 can more stably support the landslide rocks.

[0041] The elastic body 405 is in a ring shape, forming an elastic ring, and the elastic ring is arranged around the outer circumference of the hinge position 410 , so that the elastic ring can perform deformation buffering in the entire circumference and buffer the blocking plate 402 in all directions.

[0042] A plurality of the elastic rings are provided in the swing interval 404, and the plurality of elastic rings are nested and arranged in sequence. The arrangement of the plurality of elastic rings can realize buffering in multiple circumferential directions, and when the blocking plate 402 automatically adjusts the swing, the plurality of elastic rings are elastically adjusted at the same time, so as to achieve a buffering effect that automatically adapts to different impacts.

[0043] In this embodiment, the blocking plate 402 has a blocking surface facing the slope 100, and a plurality of pressure strips 407 are arranged on the blocking surface, and the plurality of pressure strips 407 are arranged at intervals on the blocking surface; the pressure strip 407 has a pressure surface facing the slope 100 to withstand the impact of the landslide of the slope 100, and the pressure surface is covered with a hard layer 406; a strip-shaped hollow groove 408 is provided in the pressure strip 407, and the hollow groove 408 is extended in a curved shape along the length direction of the pressure strip 407.

[0044] The hard layer 406 can prevent the impact of landslide rocks from damaging the pressure strip 407, and the hollow groove 408 is provided in the pressure strip 407 to enhance the deformation capacity of the pressure strip 407. The pressure strip 407 is provided on the blocking surface to play a primary buffering role against the impact of landslide rocks.

[0045] A plurality of metal balls 409 are arranged at intervals in the hollow groove 408, and the width of the metal balls 409 is larger than the width of the hollow groove 408; when the pressure strip 407 is in the original state, the metal balls 409 are clamped and fixed; when the pressure strip 407 is subjected to the impact of the landslide of the slope 100, the pressure strip 407 is locally squeezed, the width of the hollow groove 408 changes, and the metal balls 409 are squeezed and shifted in the hollow groove 408, so that the pressure strip 407 automatically adjusts its deformation and limits the local deformation of the pressure strip 407 from exceeding the set value.

[0046] When the landslide stone impacts the blocking plate 402, it is buffered and blocked by the pressure strip 407. In order to prevent the pressure strip 407 from being deformed too much when it is impacted instantly, which may cause the entire blocking structure to be destroyed, a metal ball 409 is provided. After the landslide stone impacts the pressure strip 407, it is restricted by the metal ball in the process of squeezing the pressure strip 407 to deform, and the deformation of the pressure strip 407 is limited within a set range. The metal ball is squeezed and displaced, which can make the pressure strip 407 deform again in this process, thereby buffering the landslide stone again, and the pressure strip 407 can be adjusted to be in a better supporting state, so that the landslide stone is more firmly against the pressure strip 407.

[0047] In this embodiment, the surface of the metal ball 409 is provided with multiple flat surfaces, and the multiple flat surfaces cover the entire surface of the metal ball 409. In this way, the rolling range of the metal ball 409 can be limited, and when the metal ball 409 is in a stable position, the position of the metal ball 409 can be stabilized through the abutment of the flat surfaces.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
