Description

Technical Field

[0001] The invention relates to the technical field of garden architecture, and in particular to a safe corner corridor structure. Background Art

[0002] Sidewalks are located between flower beds and lawns. Most of the corners of flower beds and lawns have protruding corners on the sidewalks. Such a design brings many inconveniences to pedestrians and non-motorized vehicles. On the one hand, there are more children and elderly people with children in residential areas. It is easy for baby carriages or elderly people to get crowded, stumble or slide sideways at the inner corners of the sidewalks, causing serious consequences and being very dangerous. At the same time, many pedestrians often take shortcuts through flower beds or lawns to pass through the inner corners of the sidewalks, trample on the flower beds or lawns, and affect greening. In recent years, in urban construction in my country, the brick design of corner aisles has been improved, and the functions of rainwater diversion and storage have been widely used, but the bricks at the corner aisles have not been set with a rainwater diversion function. The inner corners of existing corner aisles do not take into account the protection of the turning process. Pedestrians and non-motorized vehicles are prone to crowding, stumbling or sliding sideways when turning, causing personal injury. At the same time, the functions are single, and the characteristics of the corners are not effectively used to set the function of rainwater diversion for the corner aisles. Summary of the invention

[0003] In order to solve the problems in the prior art that corner corridors have no safety protection structure, pedestrians and non-motor vehicles are prone to crowding, tripping and sliding, causing personal harm, and the function is single and there is a lack of rainwater diversion devices, the present invention provides a safe corner corridor structure that can meet the safe passage requirements of corner corridors, has multiple functions, is simple in structure and is easy to implement.

[0004] In order to achieve the above-mentioned technical objectives and the above-mentioned technical effects, the present invention is implemented through the following technical solutions: a safe corner aisle structure, in which a safety block is arranged on the inner corner ground formed at the turning point of the sidewalk to form a corner aisle area that is easy to pass, and a drainage hole is provided on the safety block. A rainwater diversion device is arranged at the lower end of the drainage hole to divert rainwater according to the amount of rainwater, and a sewage well is arranged at the lower end of the rainwater diversion device.

[0005] By adopting the above technical scheme, when the present invention is used, a safety block is set at the inner corner of the sidewalk formed by the turn to form a corner aisle area that is easy to pass. The corner of the corner part of the flower bed or lawn becomes a straight edge or a curved edge, which reduces the area of ​​the flower bed or lawn at the corner, reduces the probability of pedestrians and non-motor vehicles passing on the flower bed or lawn, and prevents pedestrians and non-motor vehicles from skidding or trampling on the lawn when passing on the flower bed or lawn. At the same time, the road area that pedestrians and non-motor vehicles can pass at the corner is increased, which alleviates the congestion when multiple pedestrians pass. The corner of the corner part of the flower bed or lawn is changed to a straight edge or a curved edge, which also reduces the probability of stumbling, and reduces stumbling or sliding. The risks after the rain can be effectively protected, and the safety of pedestrians and non-motor vehicles can be effectively protected; the rainwater diversion device can discharge rainwater when the rainwater volume is small, and store excess rainwater in the water storage device through the water storage pipe when the rainwater volume is large, making the best use of the fact that water is easily accumulated in the corner area, and a large amount of rainwater can be stored in the water storage device in a short time for convenient use; at the same time, the sewer hole, the rainwater diversion device and the sewage well form a drainage channel in the corner aisle area. When the rainfall is too much or there is sewage, the corner of the sidewalk can be drained through the drainage system. At this time, there is no need to store rainwater, which prevents rainwater or sewage from gathering at the corner of the sidewalk to affect pedestrians' travel or flood flowers and plants.

[0006] Preferably, the rainwater diversion device is provided with a transition space, and a discard pipe, a water storage pipe, and a rotating device for controlling the opening and closing states of the discard pipe and the water storage pipe are arranged at the lower end of the transition space. The transition space can buffer the rainwater flowing down from the drain hole, and the rotating device controls the opening and closing states of the discard pipe and the water storage pipe. When the amount of rainwater is small, the rainwater is discharged from the discard pipe at the lower end of the transition space. When the amount of rainwater is large, the rotating device is started, the discard pipe is closed, the water storage pipe is opened, and the rainwater is discharged from the water storage pipe and stored in the water storage device.

[0007] Preferably, the rotating device includes a shell, a flexible device, rotating blades and a water-driven wheel. The shell is provided with a sliding groove for limiting the sliding trajectory of the flexible device. The flexible device is arranged in the sliding groove. The first end of the flexible device is fixed to one end of the sliding groove near the abandonment pipe, and the second end of the flexible device extends along the sliding groove to one end of the sliding groove near the water storage pipe. The second end of the flexible device is provided with a rotating blade, and the blade part of the rotating blade passes through the opening of the sliding groove. A limiting slot is provided at the lower end of the sliding groove, and an installation slot is provided on the shell near the first end of the flexible device. The water-driven wheel is rotatably arranged on the installation slot, and a pull rope is wound around the rotating shaft of the water-driven wheel, and the front end of the pull rope is connected to the second end of the flexible device. The flexible structure is arranged in the sliding groove on the shell, and the sliding groove is a semicircular track, and the space size is just enough to accommodate the flexible device to do telescopic movement in the sliding groove, which can drive the rotating blade to slide. The first end of the flexible device is fixed to the end of the sliding groove near the abandoned flow pipe, and the second end of the flexible device extends along the sliding groove to the end of the sliding groove near the water storage pipe. The second end of the flexible device is provided with a rotating blade, and the blade part of the rotating blade passes through the opening of the sliding groove. Such a design can make the rotating blade close the water storage pipe and open the abandoned flow pipe when the rainwater diversion device is not working; the water dynamic The wheel is arranged on the mounting groove near the first end of the flexible device on the shell. When a large amount of water flows through the water wheel, the water wheel will rotate. A pull rope is wound around the rotating shaft of the water wheel. The front end of the pull rope is connected to the second end of the flexible device. The rotation of the water wheel will allow the pull rope to be more wound around the rotating shaft of the water wheel. The pull rope drives the flexible device to compress and causes the rotating blades to rotate. At this time, the flow abandonment pipe is closed and the water storage pipe is opened. When the rainwater decreases or stops, the flexible structure returns to its original state, and the elastic force generated drives the rotating blades back to their original positions, closing the water storage pipe and opening the flow abandonment pipe.

[0008] Preferably, a movable ball is arranged on the shell, a limit buckle is arranged at one end of the movable ball, and a control blade is arranged at the other end, the limit buckle is arranged on the inner side of the shell, and the control blade is arranged on the outer side of the shell, the diameter of the control blade is half of the rotating blade, and the weight of the limit buckle is greater than the weight of the control blade. The weight of the limit buckle is greater than the weight of the control blade. When the water storage pipe is opened, the control blade is subjected to the force of rainwater and moves downward close to the water storage pipe wall, driving the movable ball to move, and the movable ball drives the limit buckle to move upward, and the limit buckle reaches the designated position and snaps into the limit slot. If the amount of water passing through the water wheel is not enough to make the pull rope pull the flexible structure, the limit slot can prevent the flexible structure from returning to its original state, so that the rotating blade is fixed above the waste flow pipe and the waste flow pipe is closed. When the rainfall decreases, the weight of the limit buckle is greater than the control blade, which drives the movable ball to move downward, and the movable ball drives the control blade to rise back to its original position. The diameter of the control blade is smaller than that of the rotating blade, which can facilitate the control of its movement by rainwater.

[0009] Preferably, the safety block includes two straight edges and a third edge, the third edge is a straight edge or a concave arc edge, wherein the angle formed by the two edges matches the angle of the sidewalk corner, and the two edges of the safety block fit with the two sides of the inner corner of the sidewalk. A safety block with three straight edges is used, so that the safety block is adapted to the shape of the flower bed or lawn and the inner side of the sidewalk corner, and fits tightly to form a flat corner aisle area. There is no large piece of exposed land and plants between the safety block and the inner sidewalk corner, which makes it safer for pedestrians and non-motor vehicles to pass through while protecting green plants. When a larger safety block is used, there will be excess road surface while ensuring that pedestrians and non-motor vehicles can pass freely. At this time, the safety block adopts a concave arc edge, which can increase the area of ​​the flower bed or lawn, effectively utilize space, and save materials for making the safety block. The position setting of the two straight edges allows the safety block to adapt to the shape of the flower bed or lawn and the inner sidewalk corner, and fits tightly to form a flat corner aisle area. There is no large piece of exposed land and plants between the safety block and the inner sidewalk corner, which makes it safer for pedestrians and non-motor vehicles to pass through while protecting green plants.

[0010] Preferably, the structure of the upper surface layer of the safety block is consistent with the structure of the surface layer of the sidewalk, so that the safety block can better adapt to sidewalks with different surface layer structures, and the hardness of the safety block is consistent with the hardness of the sidewalk, so as to better protect the safety of pedestrians and non-motorized vehicles passing through the corners of the sidewalk.

[0011] Preferably, the drainage holes are concentrated in the central area of ​​the safety block, so that the drainage hole resources on the safety block can be fully utilized, allowing rainwater to flow into the sewage well. At the same time, the safety block cover adopts a solid design on both sides of the sewage well, making the safety block cover the rainwater well more stable.

[0012] Preferably, the sewage well is arranged under the safety block, with a discarding outlet at the upper end, and the lower end is connected to the sewage pipe through a rainwater pipe, forming a drainage system, and the water storage device is arranged under the lawn and connected to the water storage pipe. The roadside sewage pipe can be effectively used to discharge the discarded rainwater or sewage into the drainage system, which optimizes the drainage system, increases the drainage capacity of the drainage system, and effectively solves the problem of water accumulation in corners after rain or flooding. At the same time, combined with the rainwater diversion device, the excess rainwater can be diverted into the water storage pipe for discharge and stored in the water storage device, meeting the city's rainwater storage needs, making the most of the characteristics of easy water accumulation in urban corners, and optimizing the city's rainwater storage system.

[0013] The beneficial effects of the present invention are that it realizes turning protection for pedestrians and non-motorized vehicles at corners, reduces the probability of pedestrians and non-motorized vehicles stumbling and skidding at sidewalk corners, and reduces the injuries caused by pedestrians and non-motorized vehicles after accidents at corners; it also solves the problem of pedestrians and non-motorized vehicles trampling on flower beds or lawns at corners, causing green plants to be damaged and affecting the beauty of greening. At the same time, the function of rainwater diversion is added to better discharge the accumulated water at the corners and store excess rainwater, thereby optimizing the urban drainage system.

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] like Figure 1 Figure 2 As shown, a safety corner corridor structure is provided with a safety block 1 on the inner corner formed at the turning point of the sidewalk 7. The safety block 1 is a triangular block (see Figure 3), the angle formed by the two straight edges is adapted to the angle of the corner of the sidewalk 7, and the two straight edges of the safety block 1 are fitted with the two sides of the inner corner of the sidewalk 7, which can reduce the gap between the sidewalk 7 and the lawn 6, make the connection between the lawn 6 and the sidewalk 7 smoother, and form a flat corner aisle area 2, so that pedestrians and non-motor vehicles will not slip and get injured due to the gap when passing, thereby increasing the safety of the corner aisle area 2; at the same time, the upper surface of the safety block 1 and the sidewalk 7 are arranged on the same plane, so that the safety block 1 and the sidewalk 7 road surface are integrated, so that the structure protruding from the ground at the corner of the sidewalk 7 where pedestrians and non-motor vehicles pass is reduced, making the part where pedestrians and non-motor vehicles pass more spacious and flat, and making the road surface more beautiful and open; the structure of the triangular block replaces the sharp corner of the inner corner part of the sidewalk 7 with a smooth straight edge, which can reduce the area of ​​the lawn 6 at the corner and reduce the probability of pedestrians and non-motor vehicles passing through the lawn 6 The rate is reduced, and pedestrians and non-motor vehicles are prevented from sliding or trampling on the lawn 6 when passing on the lawn 6. At the same time, the road area of ​​the sidewalk 7 where pedestrians and non-motor vehicles can pass at the corner is increased, and the congestion when multiple pedestrians or non-motor vehicles pass at the same time is alleviated. The corner of the corner part of the sidewalk 7 is replaced with a straight edge, which also reduces the probability of stumbling and reduces the risk of stumbling or sliding, effectively protecting the safety of pedestrians and non-motor vehicles when passing the corner of the sidewalk 7. At the same time, the triangular block can save materials for making the safety block 1; the two sides of the safety block 1 that fit the inner corner of the sidewalk 7 are 70 cm in length, which can completely cover the sewage well 4, and at the same time can ensure that pedestrians and non-motor vehicles safely pass through the corner aisle area 2 of the sidewalk 7; the thickness of the safety block 1 is 4 cm, which is compatible with the inner corner structure of the sidewalk 7 where the safety block 1 is located, is convenient and flexible, and is easy to disassemble; the safety block 1 is made of plastic, which is simple to make and convenient to produce.

[0024] like Figure 3 As shown, the safety block 1 is provided with 6 drainage holes 3, which are of equal diameter and spacing and are concentrated in the central area of ​​the safety block 1, so that the resources of the drainage holes 3 are fully utilized, so that rainwater can be concentrated and flow into the rainwater diversion device 24 (see Figure 4 ), and the safety block 1 covers both sides of the sewage well 4 with a solid design, making the safety block 1 more stable; a mounting slot 12 is arranged below the safety block 1, and a mounting buckle 13 is arranged at the upper end of the rainwater diversion device, and the safety block 1 is connected to the rainwater diversion device 24 through the mounting slot 12 and the mounting buckle 13; the rainwater diversion device 24 is connected to the lower part of the drain hole 3, and the rainwater diversion device 24 is provided with a transition space 8, and a discard pipe 11, a rotating device 10 and a water storage pipe 9 are arranged at the lower end of the transition space 8, and the water storage pipe 9 is connected to the water storage device 14, and the water storage device is an ecological porous fiber cotton, and the discard pipe is connected to the sewage well 4, and the rotating device 10 is fixed between the water storage pipe 9 and the discard pipe 11 by a fixing nut 15 and a fixing screw 20, and the discard pipe 11 and the water storage pipe 9 are on the same plane; the rotating device 10 (see Figure 5) includes a housing 26 (see Figure 6), a flexible structure 23, a rotating blade 16 and a control blade 18, the flexible structure 23 adopts a spring and is installed in a sliding groove 27, an opening is provided on the outside of the sliding groove 27, and a semicircular track is formed in the groove, which surrounds the outside of the fixed screw 20, and a first end of the flexible device 23 is fixed to an end of the sliding groove 27 near the abandoned flow pipe 11, and a second end of the flexible device 23 extends along the sliding groove 27 to an end of the sliding groove 27 near the water storage pipe 9, and a rotating blade 16 is provided at the second end of the flexible device 23, and a blade part of the rotating blade 16 passes through the opening of the sliding groove 27 and can move at the opening of the sliding groove 27. After the flexible device 23 is installed, it surrounds the outside of the fixed screw 20 and forms a semicircular shape, which can limit the sliding track of the flexible device 23 and ensure that the rotating blade 16 performs a rotating motion when the flexible device 23 slides; The upper end of the sliding groove 27 is a fixing nut 15, and the lower end is provided with a limit slot 22; an active ball 19 is provided on the shell 26, and a limit buckle 21 is provided on the inner part of the shell of the active ball 19, and a control blade 18 is provided on the outer part of the shell 26. When the rainwater diversion device 24 is not in use, the control blade 18 is just below the rotating blade 16, and the diameter is half of the rotating blade 16; when no water flows into the rainwater diversion device 24, the rotating blade 16 covers the mouth of the water storage pipe 9, the water storage pipe 9 is closed, and the abandoned flow pipe 11 is opened; the water impeller 17 is provided on the mounting groove 28 near the first end of the flexible device 23 on the shell 26, and a pull rope 25 is wound around the rotating shaft of the water impeller 17, and the front end of the pull rope 25 is connected to the second end of the flexible device 23. The rotation of the water wheel 17 will make the pull rope 25 more wrapped around the rotating shaft of the water wheel 17. When a certain amount of sewage or a small amount of rainwater flows through the rainwater diversion device 24, the water flow causes the water wheel 17 to rotate, and the water wheel 17 drives the pull rope 25 to wrap around the rotating shaft of the water wheel 17. The pull rope 25 drives the flexible structure 23 to compress along the semicircular path of the sliding groove 27, and the rotating blades 16 rotate along the sliding groove 27. When the water flow is too large to allow the water wheel 17 to continue rotating, the flexible structure 23 restores the deformation force to drive the pull rope 25 to disperse from the rotating shaft of the water wheel 17, and the rotating blades 16 return to the mouth of the water storage pipe 9, the water storage pipe 9 is closed, and the abandoned flow port 11 is opened. At this time, the rotating blades 16 cannot be fully opened, and the rainwater diversion device 24 does not store water.When the amount of rainwater is too large, a large amount of water flows into the rainwater diversion device 24 through the drain hole 3. After the water flow is buffered by the transition space 8, it still has a large impact force. The water flow causes the water wheel 17 to continue to rotate until it cannot rotate. The water wheel 17 drives the pull rope 25 to be wound around the rotating shaft of the water wheel 17 and tightened. The pull rope 25 drives the flexible structure 23 to be compressed along the semicircular path of the sliding groove 27. The rotating blade 16 rotates along the sliding groove 27 and covers the abandoned flow pipe 11. The water storage pipe 9 is opened, and a large amount of water flows through. The control blade 18 is forced to move downward close to the wall of the water storage pipe 9, driving the movable ball 19 to rotate. The movable ball 19 drives the limit buckle 21 to move upward, and the limit buckle 21 is inserted into the limit slot 22 to fix the flexible structure 23, so that it cannot restore its deformation when the water wheel is no longer subjected to the force of the water flow to tighten the pull rope, so that the rotating blades 16 cover the mouth of the water storage pipe 9, so that the water storage pipe 9 remains open; when the amount of rainwater decreases, the control blades 18 move upward after the force is reduced, driving the movable ball 19 to rotate, and the movable ball 19 drives the limit buckle 21 to move downward. At this time, the water wheel 17 cannot continue to be forced to rotate to tighten the pull rope 25, and cannot prevent the flexible structure 23 from restoring its original state along the sliding groove, and the rotating blades 16 move along the sliding groove. The trough rotates and covers the water storage pipe 9, the water storage pipe 9 is closed, and the abandoned flow pipe 11 is opened; the abandoned flow pipe 11 is connected to the sewage well 4 below, and the safety block, the rainwater diversion device and the sewage well 4 form a drainage channel for the corner aisle area 2. When it rains or other flooding occurs, the corner of the sidewalk 7 can be drained in time through the sewer hole 3 to prevent rainwater from gathering at the corner of the sidewalk 7 and affecting pedestrians' travel or flooding the lawn 6. The sewage well 4 is set underground at the inner corner of the sidewalk 7, with the upper end covered by the safety block 1 and the lower end connected to the sewage pipe in the residential area through the rainwater pipe 5, which optimizes the drainage system of the residential area. The drainage capacity of the drainage system in the residential area is increased, and the rainwater diversion device can store rainwater in the ecological fiber cotton when the rainwater volume is large, which meets the water storage requirements of the city; the upper surface layer of the safety block 1 is consistent with the upper surface layer of the sidewalk 7 where the safety block 1 is located, and both are flat road structures; the hardness of the upper surface layer of the safety block 1 is adapted to the hardness of the surface layer of the sidewalk 7, so that pedestrians and non-motorized vehicles can pass smoothly, and there will be no safety problems caused by the different hardness of the surface layers of the safety block 1 and the sidewalk 7; the rainwater diversion device is made of plastic, which is light, easy to make, and convenient to replace. ;

[0025] Example 2

[0026] The safety block 1 of Example 2 has two straight edges and one concave arc edge. The angle formed by the two straight edges is adapted to the angle of the corner of the sidewalk 7, and the two straight edges of the safety block 1 fit with the two sides of the inner corner of the sidewalk 7, which can reduce the gap between the sidewalk 7 and the lawn 6 and form a flat corner aisle area 2; at the same time, the upper surface of the safety block 1 and the sidewalk 7 are arranged on the same plane, so that the safety block 1 and the sidewalk 7 are integrated into one, and the structure protruding from the ground at the corner of the sidewalk 7 where pedestrians and non-motorized vehicles pass is reduced, making the part where pedestrians and non-motorized vehicles pass more spacious and flat, and making the road surface more beautiful and open; the two sides of the safety block 1 that fit with the inner corner of the sidewalk 7 are both 120 cm long, which can completely cover the sewage well 4 and can ensure that pedestrians , non-motorized vehicles can pass through, and the arc-shaped edge structure of the safety block 1 can ensure that there is enough area for pedestrians and non-motorized vehicles to pass through at the corner of the sidewalk 7, while retaining as much green lawn 6 as possible, so that the greening will not be affected by the safety block 1, and it can also save materials for making the safety block 1; the arc-shaped edge structure of the safety block 1 makes the connection between the lawn 6 and the sidewalk 7 smoother, reducing the probability of pedestrians and non-motorized vehicles stumbling or sliding when passing through the sidewalk 7, reducing the risk of green plants being trampled, and at the same time retaining the lawn 6 to the maximum extent, reducing the impact on greening; the thickness of the safety block 1 is 7cm, which is compatible with the inner corner structure of the sidewalk 7 where the safety block 1 is located, which is convenient and flexible; the safety block 1 is made of steel, which is simple to make, easy to disassemble, and has a strong bearing capacity. The rest is the same as Example 1.
