Description

Technical Field

[0001] The invention relates to the technical field of soil and water control engineering, and in particular to an ecological slope protection device for a high-cold environment. Background Art

[0002] The Qinghai-Tibet Plateau is known as the roof of the world. The high-altitude and cold regions cover an area of ​​about 2.5 million km. 2 , the daily temperature difference is large, reaching 29℃ during the day and dropping to 0℃~3℃ or even minus 15℃ at night. For the slope rock and soil in this area, it expands and transfers heat to the inside during the day, and the surface cools down and transfers freezing to the inside at night. From the monthly changes, melting is the main feature in summer and autumn, and freezing is the main feature in winter and spring. Obviously, there are small freeze-thaw cycles in daily units and long freeze-thaw cycles in monthly units in high-altitude and cold areas. The slope rock and soil are subjected to the frost heave-thaw cycle every day and the freeze-thaw changes for a long time every year, which will inevitably cause damage to the surface rock and soil of the slope. This freeze-thaw damage deterioration effect gradually weakens from the free-surface side of the slope inward.

[0003] To this end, a conservation-type ecological slope protection device and a construction method thereof, disclosed in the prior art with publication number "CN112832193A", are used to be arranged on the river slopes on both sides of a silty soil river channel, and include support piles, bamboo raft slope protection, and a fixing mechanism, wherein the support piles are fixedly inserted at the foot of the river slope, the bamboo raft slope protection is laid on the river slope, the bamboo raft slope protection is formed by splicing a plurality of bamboo raft boards together, the bamboo raft boards are mesh flat plate structures woven from bamboo sheets, the lower end of the bamboo raft slope protection is fixedly connected to the support piles in the direction in which the river extends, and the upper end is higher than the design water level of the silty soil river channel, the fixing mechanism includes a plug-in component, the plug-in component is inserted into the river slope, and the bamboo raft boards are fixed on the river slope.

The traditional anchoring structure is subject to increased load. Therefore, the anchor rods and rafts will be difficult to effectively provide traction to the slope soil during the freeze-thaw cycle.

[0025] Embodiment 1:

[0026] An ecological slope protection device for a high-cold environment, comprising:

[0027] A plurality of grid slope protection rafts 1 are connected to each other through connecting fasteners. The grid slope protection raft 1 is rectangular and has a grid water locking area 2 arranged therein. An anchor rod pulling seat 3 is also integrally formed in the middle of the grid slope protection raft 1.

[0028] Adaptive pulling anchor rods 4, the number of which is consistent with and one-to-one correspondence with the number of grid slope protection rafts 1, the adaptive pulling anchor rods 4 include upper pulling rods 5, adaptive traction telescopic sleeves 6 and lower pulling rods 7, the adaptive pulling anchor rods 4 are connected to the grid slope protection raft 1 through the cooperation of the upper pulling rods 5 and the anchor rod pulling seat 3, a telescopic elastic member is arranged in the adaptive traction telescopic sleeve 6, the upper pulling rod 5 is fixedly connected to the telescopic elastic member, the lower pulling rod 7 is fixedly connected to the adaptive traction telescopic sleeve 6, in high altitude areas, temperature changes form a periodic freeze-thaw cycle, thereby causing the slope rock and soil to expand and contract, the telescopic elastic member is used to pull the upper pulling rod 5 so that the grid slope protection raft 1 is tightly against the slope rock and soil; wherein,

[0029] A piston telescopic block 8 and a fixed block 9 are also provided in the adaptive traction telescopic sleeve 6. The adaptive traction telescopic sleeve 6, the piston telescopic block 8 and the fixed block 9 enclose a water storage tank 10. The piston telescopic block 8 and the upper pulling rod 5 perform telescopic movement synchronously. A moisture collection mechanism is also provided outside the adaptive traction telescopic sleeve 6. The moisture collection mechanism is connected with the water storage tank 10 in the adaptive traction telescopic sleeve 6 through a one-way liquid inlet hole 11. The water storage tank 10 is also connected with the grille water locking area 2 through a channel 12 opened in the upper pulling rod 5. During the periodic freeze-thaw cycle of the slope rock and soil, the piston telescopic block 8 pumps moisture unidirectionally from the moisture collection mechanism to the grille water locking area 2 through the telescopic process in the adaptive traction telescopic sleeve 6.

[0030] In this embodiment, the grid slope protection raft 1 serves as the surface covering structure of the slope, and its grid-shaped plate structure is used to abut the soil of the slope to prevent landslides. Since the slopes are mostly sandy and gravel structures, it is necessary to add anchor rods to pull the grid slope protection raft 1. At the same time, in order to solve the problems of frost heave and thawing collapse of the soil layer of the slope in high-altitude areas during the freeze-thaw cycle, the anchor rod in this embodiment adopts an adaptive pulling anchor rod 4, and the adaptive pulling telescopic sleeve 6 provided therein has a telescopic elastic part.

It has the multiple superposition effects of locking water, reducing the frost heave deformation rate of the slope, and controlling the moisture of the slope soil, which is environmentally friendly and practical.

[0031] Embodiment 2:

[0032] The moisture collection mechanism includes a protective cover 13 with a trumpet-shaped opening. The protective cover 13 is fixedly mounted on the adaptive traction telescopic sleeve 6. The protective cover 13 is mounted in an inverted state on the adaptive traction telescopic sleeve 6. A one-way liquid inlet hole 11 is arranged at the bottom of the protective cover 13. A sponge gravel moisture adsorption block 14 is filled between the protective cover 13 and the adaptive traction telescopic sleeve 6. Moisture is adsorbed by the sponge gravel moisture adsorption block 14 and deposited at the bottom of the protective cover 13. The piston telescopic block 8 adsorbs moisture into the water storage tank 10 during the extension process.

[0033] In this embodiment, the specific structure of the moisture collection mechanism is further disclosed. The moisture is collected through the protective cover 13 with a trumpet-shaped opening, and a sponge gravel moisture absorption block 14 for locking water is arranged therein. Since the sponge gravel moisture absorption block 14 has a porous structure inside, it can absorb moisture. During the installation process of the adaptive pulling anchor rod 4, a tunnel with an inner diameter greater than or equal to the maximum outer diameter of the protective cover 13 is opened on the ground, so that the adaptive pulling anchor rod 4 is sent into the tunnel, and then the soil is backfilled and compacted. Since there is moisture deep in the soil, the moisture The collection is completed by adsorption in the sponge gravel moisture adsorption block 14, and the moisture is adsorbed into the water storage tank 10 during the extension process of the piston telescopic block 8. The principle of moisture transfer is that when the piston telescopic block 8 extends, the volume of the internal water storage tank 10 increases to form a negative pressure. At this time, the gas and moisture enter the water storage tank 10 through the one-way liquid inlet hole 11, thereby completing the collection of moisture. The piston telescopic block 8 and the fixed block 9 both have a sealing piston to ensure the air tightness inside the water storage tank 10, and a one-way liquid inlet valve is provided in the one-way liquid inlet hole 11 to ensure the unidirectional movement of moisture.

[0034] Embodiment three:

[0035] A water supply trough 15 is also provided on one side of the upper pulling rod 5 inserted into the grille slope protection raft 1. The water supply trough 15 is connected to the capillary channel 16 opened in the grille slope protection raft 1. The upper and lower sides of the water supply trough 15 are sealed by sealing rubber rings 21. During the downward compression of the piston telescopic block 8, the water in the water storage tank 10 reaches the water supply trough 15 through the channel 12 in the upper pulling rod 5, and enters the capillary channel 16 of the grille slope protection raft 1 through the water supply trough 15, and the grille water locking area 2 is connected to the capillary channel 16.

[0036] In this embodiment, a structure is further disclosed in which moisture enters the capillary channel 16 through the water storage tank 10. During the rising process of the piston telescopic block 8, the volume of the water storage tank 10 decreases, causing the moisture stored inside to rise through the channel 12 and reach the water supply tank 15. Due to the sealing rubber ring 21 provided in the water supply tank 15, the moisture is transferred from the water supply tank 15 to the capillary channel 16 provided in the grid slope protection raft 1, and finally flows out from the grid water locking area 2 through the capillary channel 16. The significance of this arrangement is that the greater the frost heave-thaw shrinkage deformation of the soil during the freeze-thaw cycle, the more soil moisture is pumped upward, which is beneficial to reducing the soil deformation rate in the next melting cycle. In addition, the pumped water can also supply water to shallow-rooted plants on the surface of the slope, thereby improving the barren condition of the slope surface, further improving the soil conservation and maintenance by the plant roots, and further improving the stability of the slope while being environmentally friendly.

[0037] Embodiment 4:

[0038] A mounting block 17 and an anti-slip claw 18 are respectively threadedly mounted on one side of the upper pulling rod 5 and the lower pulling rod 7 .

[0039] A buckle connection groove 19 is also provided on the side of the grid slope protection raft 1.

[0040] The telescopic elastic member is a telescopic spring 20, the bottom of which is fixedly connected to the adaptive traction telescopic sleeve 6, and the other end of the telescopic spring 20 is fixedly connected to the end of the upper pulling rod 5 inserted into the adaptive traction telescopic sleeve 6, and the lower traction rod 7 and the adaptive traction telescopic sleeve 6 are threadedly connected.

[0041] In this embodiment, the installation and connection method of the upper pulling rod 5, the lower traction rod 7 and related structures is further disclosed, wherein threaded assembly is mostly used for connection and fixation, and the connection process is simple and practical. The telescopic elastic member in this embodiment adopts the telescopic spring 20 commonly seen in real life, and the telescopic spring 20 pulls the upper traction rod 5 to achieve adaptive anchoring and complete the smooth pumping of related water.
