[0033] Please refer to Figures 1 to 6 A preferred embodiment of the utility model provides a deepened cover plate side ditch with anti-fall and climbing functions, and the deepened cover plate side ditch mainly includes a rectangular side ditch 10, a platform cap 20, a cover plate 30, an anti-fall net 40 and a ladder 50.
[0034] The cross section of the rectangular ditch 10 is rectangular, and the rectangular ditch 10 extends along the extension direction of the road. Figure 1 , Figure 2 and Figure 7 In a specific exemplary embodiment, the deepened cover plate ditch with anti-fall and climbing functions of the utility model is located next to the highway 70. A drainage ditch 72 is arranged at the position of the dividing strip 71 of the highway 70. The drainage ditch 72 is connected to the rectangular ditch 10 through a double-walled corrugated transverse pipe 73. The rectangular ditch 10 is made of cast-in-place C20 concrete, which mainly collects rainwater from the road surface and the median strip and discharges it to the downstream. The rectangular ditch 10 is backfilled with earth, and the side close to the road surface is compacted according to the corresponding roadbed and embankment compaction requirements, and the side close to the slope is compacted at 90% compaction. The longitudinal slope of the double-walled corrugated transverse pipe 73 for drainage is generally 2%, and can be adjusted appropriately according to the actual situation, but shall not be less than 0.5%. The height of the double-walled corrugated transverse pipe 73 mouth in the rectangular ditch 10 is 20 cm from the bottom of the rectangular ditch 10. In this preferred embodiment, the internal depth of the rectangular ditch 10 is 150 cm to 200 cm, and the width is 60 cm. Figure 1As shown; and in some deeper rectangular side ditches 10, the inner depth of the rectangular side ditch 10 is greater than 200cm, such as greater than 200cm and less than 275cm, such as Figure 2 As shown. When the inner depth of the rectangular ditch 10 is greater than 200cm, a cross brace 60 is provided in the rectangular ditch 10. The two ends of the cross brace 60 are fixedly connected to the two side walls of the rectangular ditch 10. The cross brace 60 is added along the ditch wall, and one cross brace is provided every 120cm in the longitudinal direction. The cross brace 60 is made of prefabricated C20 concrete. The cross brace specification is 20cm long × 80cm wide × 20cm high, and it is 75cm away from the top surface of the cover. When the depth of the rectangular ditch 10 exceeds 200cm, a cross brace 60 of 20cm long × 80cm wide × 20cm high is prefabricated on both sides of the ditch wall to ensure the stability of the ditch structure.
[0035] Please refer to Figure 1 , Figure 2 and Figure 4 , the cap 20 is located at the top of both sides of the rectangular ditch 10, and a plurality of hooks 21 distributed longitudinally along the rectangular ditch 10 are arranged on the inner side of the bottom of the cap 20. In this exemplary embodiment, the cap 20 adopts a prefabricated C25 concrete cap, and the hook 21 adopts an 8mm diameter stainless steel screw. The hook 21 is partially cast in the cap 20 to achieve fixation. The prefabricated C25 concrete cap 20 serves as a support platform for the cover plate 30 of the ditch, and the hook 21 of the prefabricated 8mm diameter stainless steel screw serves as a fastener of the anti-fall net 40. In this exemplary embodiment, the cross-section of the cap 20 is L-shaped, and there is a step on the inner side to place the cover plate 30. The height of the cover plate 30 is consistent with the step height of the cap 20 so that when the cover plate 30 is placed on the cap 20, it can be flush with the top surface of the cap 20. The hook 21 is made of 304 stainless steel, and the hook 21 of the stainless steel screw has a diameter of 8mm and a length of 300mm. The front end of the hook 21 has a hook to hook the anti-fall net 40, and it is convenient to remove the anti-fall net 40 in an emergency. For example, at the position corresponding to the ladder 50, when a person needs to go up from there, or go down from there, the anti-fall net 40 can be temporarily removed to facilitate the passage of people. The free end of the hook 21 is a circular ring structure with a notch, and the circular ring structure with a notch is curled upward. The hook 21 is installed at a depth of 250mm downward from the top surface of the cover plate 30, and the hook 21 extends 65mm. The hook part of the hook 21 is circular and has a notch to facilitate the hanging of the anti-fall net 40. The inner diameter of the circular ring is 40mm. The anti-fall net 40 is hung in the circular hook of the hook 21 and fixed firmly.
[0036] Since the platform cap 20 is made of C25 concrete and is prefabricated, and the rectangular side ditch 10 is made of cast-in-place C20 concrete, in order to effectively fix the platform cap 20 and the rectangular side ditch 10, a layer of 2 cm thick M7.5 mortar 22 is laid between the platform cap 20 and the rectangular side ditch 10.
[0037] like Figures 1 to 3As shown, the cover plate 30 is placed on the platform cap 20 to cover the top surface of the rectangular ditch 10. The specifications of a single cover plate 30 are 59cm long × 85cm wide × 12cm high. The cover plate 30 is placed on the prefabricated C25 concrete platform cap 20, mainly to prevent falling and drain road water. The cover plate 30 uses prefabricated C30 concrete, with steel bars buried inside. A plurality of drainage holes 31 are opened on the cover plate 30 for draining road water, so that road water can enter the rectangular ditch 10. In the cover plate 30, the steel bars used are HPB300 plain round steel bars and HRB400 threaded steel bars. The steel bar lap length is 42d, and the net concrete protective layer is 30m.
[0038] The anti-fall net 40 is hung on the hook 21 and covers the top opening of the rectangular ditch 10. The net rope of the anti-fall net 40 is a moisture-resistant and anti-corrosion material such as high-strength polyethylene. The diameter of the net rope of the net body is 8mm. The net rope is made of no less than 3 single ropes, and the single rope tension is greater than 1600N; the mesh side length of the anti-fall net 40 is no more than 10cm, and the load-bearing capacity is not less than 300kg; the breaking strength of the net rope: ≥3000N, impact resistance: ≥500J, and the net rope does not break. The anti-fall net 40 is multiple pieces, and the multiple pieces of anti-fall nets 40 are connected in sequence and cover the top opening of the rectangular ditch 10. The length of a single piece of anti-fall net 40 is 100cm to 200cm. In this exemplary embodiment, the specifications of the single piece of anti-fall net 40 are 60cm wide × 100cm long. The anti-fall net 40 can prevent pedestrians from falling after the ditch cover is stolen or damaged, and also has the function of blocking debris.
[0039] like Figure 1 and Figure 2 As described, the ladder 50 is arranged on the wall of the rectangular ditch 10, and extends upward from the bottom of the rectangular ditch 10 to the top of the rectangular ditch 10. The ladder 50 is mainly used for maintenance personnel to climb in and out to clean up debris in the ditch, and also takes into account the function of escaping from falling personnel. For example, when a person falls, he can climb out of the ditch through the ladder 50.
[0040] The ladder 50 includes a plurality of ladder units distributed up and down, such as Figure 6As shown, each ladder unit includes two fixed rods 51 fixedly mounted on the wall of the rectangular ditch 10 and horizontally distributed to each other, and a U-shaped footrest 52 sleeved on the two fixed rods 51, and the two ends of the U-shaped footrest 52 are respectively connected to the two fixed rods 51 so that the U-shaped footrest 52 is arranged horizontally. The fixed rod 51 is formed by stamping 16mm diameter steel bars, and the U-shaped footrest 52 is formed by plastic injection molding, and the fixed rod 51 and the U-shaped footrest 52 are fixedly arranged. In one embodiment, a 16mm diameter hole is opened in the wall of the rectangular ditch 10 to facilitate the insertion of the fixed rod 51, and fixed by mortar. Or in another embodiment, the end of the fixed rod 51 has a bend and is cast together when the rectangular ditch 10 is cast, and the ladder unit is fixed on the wall of the rectangular ditch 10. The U-shaped footrest 52 protrudes 10cm from the inner wall of the rectangular ditch 10, which is convenient for people to step on, but not too protruding. The U-shaped footrest 52 is provided with anti-slip grooves 53 to prevent the feet from slipping when climbing. The U-shaped footrest 52 is provided with a reflector 54 on the upward side. The reflector 54 can be a light strip or a reflective point. When external light shines on it, it can reflect light for people to observe. On the one hand, it is convenient for people to find the ladder 50 in the rectangular side ditch 10, and on the other hand, it is convenient for people to step on the U-shaped footrest 52 when climbing the ladder 50.
[0041] The multiple ladder units on each ladder 50 are divided into two rows and distributed vertically. The multiple ladder units distributed in the two rows are staggered in height to facilitate climbing. The vertical spacing of the ladder units distributed in the same row is 300mm~360mm; the horizontal spacing of the ladder units distributed in the two rows is 280mm~320mm. In an exemplary embodiment, the two rows of ladder units of each ladder 50 are staggered left and right, with a vertical spacing of 360mm and a horizontal spacing of 300mm. The ladder 50 is buried as close to the bottom of the ditch as possible, the top ladder unit is 36cm away from the top surface of the cover plate 30, and the bottom ladder unit must not be more than 50cm away from the bottom of the ditch.
[0042] The cross brace 60 and the ladder 50 are staggered to avoid the cross brace 60 blocking the use of the ladder 50. There are multiple ladders 50, which are distributed longitudinally along the rectangular ditch 10, and the distance between two adjacent ladders 50 is 10m-15m. In this exemplary embodiment, the ladder 50 is arranged every 10m, and when the longitudinal length of the deepening cover plate ditch is less than 10m, at least one ladder 50 is arranged.
[0043] During implementation, a deepened cover plate side ditch is set in the super-elevated section of a small-radius flat curve, the excavation section of a concave curve and the deepening return flow section of the tunnel entrance, wherein a hook 21 of a stainless steel screw is set on the platform cap 20, and an anti-fall net 40 is hung. The anti-fall net 40 can prevent people from falling to the bottom of the rectangular side ditch 10 due to the missing cover plate 30. At the same time, the anti-fall net 40 also has the function of blocking debris, and can to a certain extent prevent garbage from falling to the bottom of the rectangular side ditch 10 to cause blockage and the like and affect drainage; a ladder 50 is set at the ditch wall of the rectangular side ditch 10, which can facilitate maintenance personnel to go up and down the rectangular side ditch 10 to clean up debris, silt, garbage, etc. in the ditch, while taking into account the function of escaping for fallen people, and the fallen people can climb out of the rectangular side ditch 10 along the ladder 50; when the rectangular side ditch 10 has a certain ditch depth, a cross brace 60 is set to ensure the stability of the ditch structure.
[0044] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
