Description

Technical Field

[0001] The invention belongs to the technical field of civil engineering, and in particular relates to a ski slope anti-skiing device and method with anti-skiing and water-collecting functions. Background Art

[0002] Landslides primarily occur in mountainous and hilly areas. For ski resorts built on mountainous terrain, the destruction of vegetation and the infiltration of snowmelt can alter slope stability, making them more susceptible to landslides and posing a significant threat to life and property. Currently, anti-slip measures are primarily implemented using either single anti-slip piles or a combination of anti-slip piles and anchor cables. However, both methods have drawbacks. For single anti-slip piles, the pile length and diameter are typically large to ensure slope soil stability, requiring specific soil quality, slope gradient, and water seepage. For a combination of anchor cables and anti-slip piles, the construction process is generally complex, costly, and less applicable. The presence of water is a significant factor affecting slope stability in slope engineering projects. For ski resort slopes, the snow layer partially melts due to temperature fluctuations. The infiltration of snowmelt into the soil can significantly impact soil stability, significantly reducing the effectiveness of these two anti-slip measures. For natural ski slopes, landslides pose a significant threat to the lives and property of participants and spectators. Natural ski resorts generally have slope restrictions. If anchor cables and anti-slip piles are used in combination, it will undoubtedly increase costs. However, the safety of using only anti-slip piles is obviously lower than that of using anchor cables and anti-slip piles in combination. Moreover, the above two methods cannot effectively prevent the snow layer on the slope from slipping and monitor it in real time. Summary of the Invention

[0010] Furthermore, the hydraulic telescopic rods connected to the four corners of the slope panel are used to control the inclination angle of the slope panel, and the hydraulic telescopic rods connected to the middle of the slope panel are used to lift the slope panel from the middle and move it in a direction perpendicular to the slope surface and away from the slope surface.

[0011] Furthermore, the slope panel is made of high-strength stainless steel, a condensation pipe is provided at the bottom of the slope panel, and an anti-slip layer is provided at the top.

[0012] Furthermore, the slope snow layer stability monitoring system includes a stress sensor, a signal transmitting device, a signal receiving device, and a background processing system. The stress sensor is used to monitor the stress data on the slope snowmelt water collection system. The signal transmitting device is used to send the stress data to the signal receiving device. The signal receiving device is used to transmit the received stress data to the background processing system. The background processing system is used to control the slope snow layer stabilization system and the slope snowmelt water collection system according to the processing results to achieve control of the slope snow layer stability.

[0013] The present invention also provides a method for using a ski slope anti-skid device with anti-skid and water-collecting functions, the specific steps of which are as follows:

[0014] S1 determines the size of the precast piles based on the soil conditions of the ski slope and slope stability calculations.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] The present invention discloses a ski resort slope anti-skid device with anti-skid and water-collecting functions. The device comprises a prefabricated pile body, a slope snow layer stabilization system, a slope snowmelt water collection system and a slope snow layer stability monitoring system. The device can integrate snowmelt water collection, landslide prevention and slope stability monitoring. The device is convenient to construct and install, has low investment cost, is easy to collect and process data, and is relatively convenient to maintain in the later stage. The device can overcome the problem that the current traditional anti-skid structure has a single function and poor effect.

[0019] When the ski slope anti-skid device of the present invention is used, the prefabricated pile body is driven into the slope soil by methods such as pile sinking, and as an important component of the anti-skid structure, it can stabilize the slope soil; through structural design, the hollow structure of the prefabricated pile body enables it to have the function of storing snowmelt water; the prefabricated pile body serves as the mother body for fixing the upper hydraulic telescopic mechanism, providing a fixing point for the upper structure, thereby realizing the protection and stability monitoring of the snow layer on the slope; the slope snow layer stabilization system is mainly composed of a slope panel and a hydraulic telescopic mechanism; the slope panel is an important structural component for ensuring the flatness and stability of the ski surface surface, and it is covered with a certain thickness of snow layer to ensure that skiers pass smoothly and safely; the slope panel is generally set to be parallel to the slope surface.

DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1 to 4 As shown, the present invention provides a ski resort slope anti-skid device with anti-skid and water-collecting functions, which is mainly composed of a prefabricated pile body, a slope snow layer stabilization system, a slope meltwater collection system, and a slope snow layer stability monitoring system. The prefabricated pile body is used to stabilize the slope soil and can also serve as a fixed matrix of the slope snow layer stabilization system and a matrix of the slope meltwater collection system; the slope snow layer stabilization system is arranged on the top of the prefabricated pile body to stabilize the slope snow layer; the slope meltwater collection system mainly collects meltwater, which can greatly reduce the impact of water on the stability of the slope soil and is more conducive to ensuring the safety of the slope; the slope snow layer stability monitoring system can control the slope snow layer stability through data analysis and then control the slope snow layer stabilization system to achieve control of the slope snow layer stability.

[0030] The precast pile is a hollow structure made of reinforced concrete. The bottom end of the pile is a conical reinforcement, which is a solid structure. The precast pile is driven into the slope soil by methods such as pile sinking. As an important part of the anti-slip structure, it can stabilize the slope soil.

[0031] The slope snowmelt water collection system includes a pile water reservoir 5, a pile water inlet channel 3, an impermeable push-pull plate 8 and a permeable push-pull plate 14. The pile water reservoir 5 composed of the hollow structure of the prefabricated pile body is used to temporarily store the collected slope snowmelt water. A number of circular hole pile water inlet channels 3 are arranged between the wall of the pile water reservoir 5 and the outer wall of the prefabricated pile body, so that the snowmelt water can be collected into the pile water reservoir 5. The impermeable push-pull plate 8 and the permeable push-pull plate 14 are arranged between the top of the prefabricated pile body and the slope snow layer stabilization system. The impermeable push-pull plate 8 is arranged on the downward side of the slope, and the permeable push-pull plate 14 is arranged on the uphill side of the slope. The impermeable push-pull plate 8 and the permeable push-pull plate 14 can be relatively displaced along the tracks arranged on their two side edges with the slope snow layer stabilization system to ensure the stability of the snow layer on the upper side of the slope; a flange with screw holes is reserved at the top end of the prefabricated pile body, and a hinge support 1 is arranged on the flange for easy docking with the upper slope snow layer stabilization system.

[0032] Preferably, a water level sensor 4 is installed in the pile water reservoir 5 to control a water pump 6 located at the bottom of the pile water reservoir 5 to discharge the accumulated snowmelt water through a water pumping pipe 7 .

[0033] like Figures 6-7 As shown, the impermeable push-pull plate 8 and the permeable push-pull plate 14 are made of high-strength stainless steel. The permeable push-pull plate 14 is provided with a large number of small pores, which allow the water after the melted snow layer on the slope to penetrate. There is a groove at the lower end of the inner side of the permeable push-pull plate 14. The groove serves as a water diversion channel 17 to collect the infiltrated melted snow water into the pile water reservoir 5. At the same time, the permeable push-pull plate 14 can stabilize the outer snow layer.

[0034] The slope snow layer stabilization system includes a hydraulic telescopic mechanism and a slope panel 16. The slope panel 16 is two flat plates connected by hinges 10 and a rotating shaft 9. The precast pile body serves as the fixed mother body of the slope snow layer stability system and provides a fixed point for the hydraulic telescopic mechanism. The bottom of the hydraulic telescopic mechanism is universally hinged to the top of the precast pile body, and the slope panel 16 is universally hinged to the top of the hydraulic telescopic mechanism. Under normal circumstances, the slope panel 16 is a plane. When the slope snow layer is unstable and tends to slide down, it can be lifted up by the hydraulic telescopic mechanism to prevent the slope snow layer from sliding down.

[0035] The hydraulic telescopic mechanism is composed of multiple hydraulic telescopic rods 2. The bottom ends of the multiple hydraulic telescopic rods 2 are fixed on a flange with the same diameter as the prefabricated pile body, and are connected to the flange through a universal hinge, so that they can be freely extended and retracted in any direction; the top ends of the multiple hydraulic telescopic rods 2 are respectively hinged to the four corners and the middle of the bottom end face of the slope panel 16. The hydraulic telescopic rods 2 at the four corners can control the inclination angle of the slope panel 16, and are used to adjust its angle after installation to meet the angle requirements of the slope 12 of the ski resort. The hydraulic telescopic rod 2 in the middle can lift the slope panel 16 from the middle after the slope snow layer stability monitoring system issues an early warning, thereby stabilizing the slope snow layer and preventing it from sliding.

[0036] Preferably, the slope panel 16 is made of high-strength stainless steel. The slope panel 16 can move in a direction perpendicular to the slope surface and away from the slope surface under the action of the hydraulic telescopic mechanism.

[0037] Preferably, a condensation tube is provided under the slope panel 16. The presence of the hollow cavity in the slope snow layer stabilization system makes the snow layer on the slope panel more likely to melt and slide. The provision of the condensation tube can prevent the snow layer on the slope panel 16 from melting. The top end surface of the slope panel 16 is treated with an anti-slip treatment to ensure that the snow layer and the end surface of the slope panel 16 remain relatively stable.

[0038] Preferably, five hydraulic telescopic rods 2 can be set, which are respectively located at the four corners and the center of the slope panel 16. The waterproof push-pull plate 8 is located in front of the two hydraulic telescopic rods 2 on the downward side of the slope, and the permeable push-pull plate 14 is located in front of the two hydraulic telescopic rods 2 on the uphill side of the slope. The waterproof push-pull plate 8 and the permeable push-pull plate 14 can both move relative to each other along the tracks set on their two side edges as the hydraulic telescopic rods 2 are extended and retracted.

[0039] The slope snow layer stability monitoring system is mainly composed of a stress sensor installed on the inner side of the permeable push-pull plate 14, a signal transmitter, a signal receiver, and a background processing system. It can collect stress data on the permeable push-pull plate 14 in real time, and send it back to the signal receiver through the signal transmitter. The collected data is analyzed in real time through the background processing system. When the monitored data has a large mutation, the system sends different levels of warning information to the supervisor, and at the same time controls each hydraulic rod to make corresponding displacement to achieve control of the stability of the slope snow layer.

[0040] Preferably, Figure 5 As shown, the interior of the pile water reservoir 5 is treated with anti-seepage treatment to effectively prevent pile corrosion. At the same time, a filter screen 15 is provided at the water inlet of the pile water inlet channel 3, and the pile water inlet channel 3 is obtained by pre-embedding a PVC pipe in the prefabricated pile body.

[0041] Except for the prefabricated pile body, the rest of the parts are integrated into one. The hydraulic telescopic mechanism is universally hinged on a disc with the same diameter as the pile body. Bolt holes are left on the disc, which can be docked with the top of the pile body and fixed with bolts.

[0042] Specific operation methods and processes;

[0043] First, according to the soil conditions of the ski slope, the required length and diameter of the prefabricated piles are determined through slope stability calculations. After prefabrication in the factory, they are transported to the site and driven into the slope. Figure 6 The slope snow stabilization system shown is fixed by screws to the reserved holes on the top of the prefabricated pile body.

[0044] Secondly, the hydraulic rods of the hydraulic telescopic mechanism are adjusted according to the thickness and gradient of the snow layer on the slope, so that the slope panel 16 remains parallel to the slope, thereby ensuring the uniform thickness of the snow layer on the slope. The outer sides of the multiple hydraulic rods on the uphill side of the slope are equipped with permeable baffles 14, whose area can be adjusted according to the extension and contraction of the two hydraulic rods on the upper side. The permeable baffles 14 can prevent the snow layer from sliding down the slope while allowing melted snow water to pass through. The permeated snow water enters the pile water reservoir 5 through the pile water inlet channel 3. The inner side of the permeable baffles 14 is installed with a stress sensor, which can transmit the stability of the upper snow layer in real time to the background through a signal transmitter for data analysis and processing. The outer sides of the multiple hydraulic rods on the downhill side of the slope are equipped with impermeable baffles 8 to prevent the snow layer below the slope from entering the device.

[0045] Finally, when the background data processing system detects a sudden change in the returned data, it will send different levels of warning text messages to the supervisors, and at the same time send a movement command to the hydraulic system. By controlling the displacement of several hydraulic rods, it adjusts the angle between the slope panel and the slope surface and the folding height of the slope panel, thereby achieving the purpose of preventing the snow layer from sliding down the slope.

[0046] The melted snow water collected by the permeable baffle 14 passes through the filter screen 15 and enters the pile water reservoir 5 from the pile water inlet channel 3. The water pump 6 in the water reservoir works under the control of the water level sensor 4. The pumped water is discharged to the surface through the pumping pipe 7 and is reused after being collected uniformly.

[0047] Depending on the width of the ski slope, multiple of the above-mentioned devices can be closely arranged. The stress on each single device can be monitored in real time through the background data monitoring system. When a sudden change in the stress data of the snow layer at a certain point on the slope is detected, the hydraulic telescopic rods of all devices on the horizontal line can be controlled to make the same displacement, thereby achieving the purpose of stabilizing the snow layer on the slope and preventing landslides.
