Description

Technical Field

[0002] Geological disasters refer to geological phenomena such as landslides, mud-rock flows, ground subsidence, ground fissures, and ground subsidence that are caused by natural or human factors and endanger people's lives and property safety. Apart from factors such as topography and landforms, sudden heavy rainfall and continuous rainfall in local areas are the main factors that induce geological disasters such as landslides, mud-rock flows, and so on.

[0003] Traditional geological disaster prevention and control mainly uses effective engineering means such as anchoring, anti-slip piles, and anti-slip retaining walls to change the process of these geological disasters in order to reduce or prevent the occurrence of disasters. However, due to the influence of topography, such as steep slopes of more than 45 degrees or loose soil slopes, it is impossible to implement such control projects in many places; at the same time, such prevention and control projects have long construction time and large investments, and are mainly large-scale geological disaster hazard remedial measures taken after the occurrence of geological disaster hazards; and for many small and medium-sized hazard points and places where hazard points are scattered, they cannot be effectively prevented due to funding constraints, and thus the probability of geological disasters caused by precipitation in small and medium-sized hazard points and places where hazard points are scattered cannot be reduced; therefore, there is an urgent need for a universal rainfall collection and drainage device and a collection and drainage system, which can be applied to geological disaster hazard points to reduce the probability of geological disasters.

[0069] Specifically, the drainage pipe 16 adopts the current relatively mature technology, using PVC pipes, cement pipes, braided pipes, cement ditches, etc., laid on the surface or underground of the geological disaster risk point to form a network drainage system.

[0070] Example 1

[0071] The water collection and drainage device described in this embodiment is mainly composed of a water collection panel 1, a water storage tank, a drainage structure, and a fixed support device.

[0072] The water collection panel 1 is a rectangular fabric cut from waterproof fabric; the main feature of the water collection panel 1 is that it has a certain degree of waterproofness, and precipitation cannot penetrate the water collection panel 1, and can only be collected in a certain direction according to the height angle of the water collection panel.

[0073] See also Figure 1 , 5 As shown, the surface of the water collection panel 1 is distributed with guide plates 20, which are made of waterproof fabric and fixed on the surface of the water collection panel 1 by sewing technology. The guide plates 20 are mainly used to increase the precipitation collection area, reduce the flow rate of precipitation on the surface of the water collection panel 1, and make the precipitation gather around the first permeable hole 41;

[0074] The lower end of the surface of the water collection panel 1 is distributed with a different number of first water permeable holes 41, and rainwater is collected into the water storage tank through the first water permeable holes 41; the water collection panel 1 is surrounded by connecting holes 2, and one of the methods of using the connecting holes 2 is shown in FIG. Figure 5 As shown, the first support rod 13 passes through the connection hole 2 on the water collecting panel 1, and the upper and lower sides of the connection hole 2 are fixed by fixing bayonet 18 to prevent the upper and lower water collecting panels 1 stacked on the edge from sliding up and down on the first support rod 13 to affect the use of the device.

[0075] The water storage tank is made of chlorinated polyvinyl chloride plastic; the water storage tank is composed of multiple independent main water storage tanks 8 and an auxiliary water storage tank 9, and the main water storage tank 8 and the auxiliary water storage tank 9 are connected through a connecting port 12; Figure 3 As shown, the auxiliary water storage tank 9 is fixed to the bottom or side of the main water storage tank 8 through the connection port 12. According to the needs, one main water storage tank 8 can be connected to and penetrate multiple auxiliary water storage tanks 9; see Figure 4 As shown, the auxiliary water tank 9 can also be arranged inside the main water tank 8. After the auxiliary water tank 9 is filled, the accumulated water is introduced into the main water tank 8 through the second water permeable holes 42 on the surface of the auxiliary water tank 9 and discharged from the overflow pipe 6.

[0076] The volume of the auxiliary water storage tank 9 is determined according to the water consumption of vegetation around the geological disaster risk point, and mainly reserves the water consumption of vegetation around the geological disaster risk point during non-rainfall periods; Figure 3 As shown, the precipitation collected in the auxiliary water storage tank 9 is slowly introduced into the soil 17 near the vegetation at the geological disaster risk point through the capillary line 5; the capillary line 5 is a rope of different thicknesses and lengths woven from various plant fibers. One end of the capillary line 5 is connected to the auxiliary water storage tank 9 and is completely immersed in the accumulated water, and the other end is placed or buried deep in the soil 17 surface or soil layer at the geological disaster risk point. The water in the water storage tank is infiltrated into the soil through the capillary phenomenon of the capillary line 5, meeting the water demand of trees, grass and other plants around the drainage device.

[0077] The volume of the main water storage tank 8 is determined according to the historical precipitation of short-term heavy rain, rainstorm, heavy rainstorm and extremely heavy rainstorm around the geological disaster risk point, ensuring that the main water storage tank 8 can timely and temporarily store the precipitation collected by the water collection panel 1.

[0078] See also Figure 3As shown, in this embodiment, in order to ensure that when rainwater from the upper end of the water collection panel 1 is collected at the lower end of the water collection panel 1, the precipitation has sufficient residence time to enter the main water storage tank 8 through the first water permeable hole 41 on the surface of the water collection panel 1, the first water permeable hole 41 area at the lower end of the water collection panel 1 and the main water storage tank 8 connection area, the lower end of the water collection panel 1 is U-shaped. At the same time, the connecting buckle 7 passes through the connecting hole 2 on the water collection panel 1 and the connecting hole on the outer shell of the main water storage tank 8 to fix the water collection panel 1 and the main water storage tank 8 together.

[0079] An overflow pipe 6 is installed on the back of the main water storage tank 8, see Figure 3 , 5 As shown, the mouth of the overflow pipe 6 of the main water storage tank 8 is higher than the connection port 12 between the main water storage tank 8 and the auxiliary water storage tank 9, ensuring that the precipitation collected by the device first enters the auxiliary water storage tank 9. After the auxiliary water storage tank 9 is full, the excess water enters the main water storage tank 8, and then is introduced into the drainage pipe through the overflow pipe 6; the overflow pipe 6 is a PVC pipe, one end of the overflow pipe 6 is glued and connected to the main water storage tank, and the other end is snap-connected to the drainage pipe 16. After the water storage space volume in the auxiliary water storage tank 9 is filled with precipitation, the excess precipitation will be temporarily stored in the main water storage tank 8. While collecting precipitation, the main water storage tank 8 will flow the precipitation back to the drainage pipe 16 laid on the surface or underground of the geological disaster risk point through the overflow pipe 6, and discharge the excess precipitation around the geological disaster risk point, thereby avoiding oversaturation of water in the soil around the geological disaster risk point, inducing geological disasters such as collapse and mudslides.

[0080] The drainage pipe network is a network drainage system that uses PVC pipes to be laid on the surface or underground of the geological hazard risk point to form a network. It mainly drains the excess water overflowing from the overflow pipe into the river or ditch outside the geological hazard risk point, thereby realizing the transfer of precipitation and ensuring the relative stability of the water in the geological structure around the geological hazard risk point, thereby ensuring the stability of the geological hazard risk. Figure 5 As shown, the diameter of the PVC pipe in this embodiment is determined by the precipitation of short-term heavy rain, rainstorm, heavy rainstorm and extremely heavy rainstorm around the geological disaster risk point.

[0081] The connection device of this embodiment is composed of a connection hole 2, a connection buckle 7 and a connection rope 3 on the surface of the water collection and drainage device. The edge areas of the water collection panels 1 of different shapes or the same shape overlap each other up and down to align the connection holes 2. The connection buckle 7 passes through the connection hole 2, and the connection between multiple devices is realized through the connection buckle 7. The connection buckle 7 can be a nut structure or a mortise and tenon structure, and the fixation between multiple devices is mainly achieved through threads or plug-in, bayonet, etc., so that the structure of the water collection and drainage system is relatively stable and not easy to fall apart when it is subjected to strong winds or heavy rainfall; the connection rope 3 is a rope with adjustable length, and there is no fixed restriction on the material, see Figure 2One end of the connecting rope 3 is fixed on the surface or the back of the water collector device, and the other end is fixed on the surface or the back of the water collector device. Figure 5 As shown, it is connected to the trunk of the native tree 19 around the geological disaster risk point or to the fixed support device in this embodiment by tying or other means; at the same time, due to terrain restrictions, during the laying and use of the device of the present invention, the edge parts of the water collection panels 1 of each device cannot overlap with each other due to factors such as trees or distance between the independent devices, and cannot be directly connected and fixed to each other through the connecting holes 2 and the connecting buckles 7. The connecting ropes 3 between the independent devices can also be used to achieve the mutual connection between the connecting ropes 3 and the connecting ropes 3, and the connecting ropes 3 and the connecting holes 2, see Figure 5 As shown, the connection between multiple drainage devices is achieved.

[0082] In this embodiment, the first support rod, the second support rod, and the third support rod are all made of plastic. Figure 5 As shown, one end of the first support rod 13 is inserted into the soil 17, and the other end passes through the connecting hole 2 on the water collecting panel 1, and is fixed to the water collecting panel 1 using the fixing bayonet 18 to prevent the water collecting panel 1 from sliding on the first support rod 13; one end of the second support rod 14 is inserted into the soil 17, and the other end is connected to the bottom of the auxiliary water storage tank 9, supporting and fixing the auxiliary water storage tank 9 to prevent the auxiliary water storage tank 9 from being displaced or overturned due to the increase or decrease of the accumulated water; one end of the third support rod 15 is inserted into the soil 17, and the other end is connected to the side of the main water storage tank 8 to support and fix the main water storage tank 8 to prevent the main water storage tank 8 from being displaced or overturned due to the increase or decrease of the accumulated water.

[0083] Example 2

[0084] The water collection and drainage device described in this embodiment is mainly composed of a water collection panel 1, a water storage tank, a drainage structure, and a fixed support device.

[0085] The water collection panel 1 is a rectangular fabric cut from a stainless steel plate.

[0086] See also Figure 6 , 8 As shown, guide plates 20 are distributed on the surface of the water collection panel 1. The guide plates 20 are made of stainless steel plates and are fixed on the surface of the water collection panel 1 by welding technology. The guide plates 20 are mainly used to increase the precipitation collection area, reduce the flow rate of precipitation on the surface of the water collection panel 1, and collect precipitation around the first water permeable hole 41.

[0087] The shape of the water collection panel 1 varies depending on the shape of the gaps between trees in the geological disaster treatment environment, and can be various triangles, polygons, circles, etc. Figure 6As shown, the water collection panel 1 in this embodiment is rectangular; different numbers of first water permeable holes 41 are distributed in the central area of ​​the water collection panel 1, and rainwater is collected into the water accumulation bag through the first water permeable holes 41.

[0088] See also Figure 6 As shown, the water collecting panel 1 has connection holes 2 around it. One of the methods of using the connection holes 2 is shown in FIG. Figure 7 As shown, the first support rod 13 sequentially passes through the connecting holes 2 on the two water-collecting panels 1 with overlapping edges, and the upper and lower water-collecting panels 1 with overlapping edges are fixed by a fixing bayonet 18 to prevent the upper and lower water-collecting panels 1 with stacked edges from sliding up and down on the first support rod 13, affecting the use of the device.

[0089] The bag body in this embodiment is made of waterproof cloth; see Figure 8 As shown, the auxiliary water bag 11 is fixed to the bottom or side of the main water bag 10 through the connecting port 12. According to the needs, one main water bag 10 can be connected to and penetrate multiple auxiliary water bags 11; see Fig. 9 As shown, the auxiliary water bag 11 can also be set inside the main water bag 10. After the auxiliary water bag 11 is filled, the accumulated water is introduced into the interior of the main water bag 10 through the second water permeable holes 42 on the surface of the auxiliary water bag 11 and discharged from the overflow pipe 6.

[0090] The volume of the auxiliary water storage bag 11 is determined according to the water consumption of vegetation around the geological disaster risk point, and mainly reserves the water consumption of vegetation around the geological disaster risk point during non-rainfall periods; see Figure 8 As shown, the precipitation collected in the auxiliary water-collecting bag 11 is slowly introduced into the soil 17 near the vegetation at the geological disaster risk point through the capillary line 5. The capillary line 5 is a rope of different thicknesses and lengths woven from polymer synthetic fibers; one end of the capillary line 5 is connected to the auxiliary water-collecting bag 11 of the water collector and is completely immersed in the accumulated water, and the other end is placed or buried deep in the soil 17 surface or soil layer at the geological disaster risk point. The water in the water-collecting bag is infiltrated into the soil through the capillary phenomenon of the capillary line 5, so as to meet the water demand of trees, grass and other plants around the drainage device.

[0091] The volume of the main water storage bag 10 is determined according to the historical precipitation of short-term heavy rain, rainstorm, heavy rainstorm and extremely heavy rainstorm around the geological disaster risk point, ensuring that the main water storage bag 10 can timely and temporarily store the precipitation collected by the water collection panel 1.

[0092] See also Figure 6As shown, in this embodiment, in order to ensure that rainwater on the upper end of the water collection panel 1 is collected in the central area of ​​the water collection panel 1, the precipitation has sufficient residence time to enter the main water storage bag 10 through the first water permeable hole 41 on the surface of the water collection panel 1, and guide plates 20 of different sizes are distributed on the surface of the water collection panel 1, so as to increase the precipitation collection area, reduce the flow rate of precipitation on the surface of the water collection panel 1, and collect the precipitation around the first water permeable hole 41.

[0093] See also Figure 8 As shown, an overflow pipe 6 is installed inside the main water bag 10, and the mouth of the overflow pipe 6 in the main water bag 10 is higher than the connection port 12 between the main water bag 10 and the auxiliary water bag 11, ensuring that the precipitation collected by the drainage device first enters the auxiliary water bag 11, and when the auxiliary water bag 11 is full, the excess water enters the main water bag 10, and then is introduced into the drainage pipe 16 through the overflow pipe 6. The overflow pipe 6 is made of a stainless steel pipe, one end of which is connected to the main water bag, and the other end is connected to the drainage pipe 16, and the overflow pipe 6 is connected to the main water bag 10 and the drainage pipe 16 by a buckle. After the water storage space in the auxiliary water storage bag 11 is filled with precipitation, the excess precipitation will be temporarily stored in the main water storage bag 10. While collecting precipitation, the main water storage bag 10 will flow the precipitation back to the drainage pipe 16 laid on the surface or underground of the geological disaster risk point through the overflow pipe 6, and discharge the excess precipitation around the geological disaster risk point, thereby avoiding oversaturation of water in the soil around the geological disaster risk point, inducing geological disasters such as collapse and mudslides.

[0094] The drainage pipe network adopts the current mature technology, using cement pipes to be laid on the surface or underground of the geological hazard risk point to form a network drainage system, mainly to drain the excess water overflowing from the overflow pipe into the river or ditch outside the geological hazard risk point, so as to achieve the transfer of precipitation and ensure the relative stability of the water in the geological structure around the geological hazard risk point, thereby ensuring the stability of the geological hazard risk. Figure 8 As shown, in this embodiment, cement pipes are used to connect and form a drainage network, and the diameter of the cement pipes is determined by the precipitation of short-term heavy rain, rainstorm, heavy rainstorm, and extremely heavy rainstorm around the geological disaster risk point.

[0095] The connection device of this embodiment is composed of a connection hole 2, a connection buckle 7 and a connection rope 3 on the surface of the water collection and drainage device. The edge areas of the water collection panels 1 of different shapes or the same shape overlap each other up and down to align the connection holes 2. The connection buckle 7 passes through the connection hole 2, and the connection between multiple devices is realized through the connection buckle 7. The connection buckle 7 can be a nut structure or a mortise and tenon structure, and the fixation between multiple devices is mainly achieved through threads or plug-in, bayonet, etc., so that the structure of the water collection and drainage system is relatively stable and not easy to fall apart when it is subjected to strong winds or heavy rainfall; the connection rope 3 is a rope with adjustable length, and there is no fixed restriction on the material, see Figure 8As shown, one end of the connecting rope 3 is fixed on the surface or the back of the water collector device, and the other end is fixed on the surface or the back of the water collector device. Figure 8 As shown, it is connected to the trunk of the native tree 19 around the geological disaster risk point or to the fixed support device of this embodiment by tying or other means; at the same time, due to terrain restrictions, during the laying and use of the device of the present invention, the edge parts of the water collection panels 1 cannot overlap with each other due to factors such as trees or distance between the independent devices, and cannot be directly connected and fixed to each other through the connecting holes 2 and the connecting buckles 7. The connecting ropes 3 between the independent devices can also be used to achieve the mutual connection between the connecting ropes 3 and the connecting ropes 3, and the connecting ropes 3 and the connecting holes 2, see Figure 5 As shown, the connection between multiple drainage devices is achieved.

[0096] In this embodiment, the first support rod, the second support rod, and the third support rod are all made of stainless steel in the form of tubes, sticks, or other heterogeneous objects. Figure 8 As shown, one end of the first support rod 13 is inserted into the soil 17, and the other end passes through the connection holes 2 on the two water collection panels 1, and is fixed to the water collection panels 1 using the fixing bayonet 18 to prevent the two water collection panels 1 from sliding on the first support rod 13. One end of the second support rod 14 is inserted into the soil 17, and the other end is connected to the bottom of the auxiliary water accumulation bag 11, supporting and fixing the auxiliary water accumulation bag 11 to prevent the auxiliary water accumulation bag 11 from being displaced or overturned due to the increase or decrease of accumulated water. One end of the third support rod 15 is inserted into the soil 17, and the other end is connected to the bottom of the main water accumulation bag 10, supporting and fixing the main water accumulation bag 10 to prevent the main water accumulation bag 10 from being displaced or overturned due to the increase or decrease of accumulated water.
