Description

Technical Field

[0001] The utility model relates to the technical field of road drainage ditch construction, in particular to a multi-crack drainage ditch structure combining a prefabricated cover plate with a cast-in-place ditch body. Background Art

[0002] Road drainage is an important part of municipal engineering. Roads without drainage pipes generally use side ditches for drainage. There are two types of side ditches: prefabricated and cast-in-place. The surface of prefabricated side ditches is smooth and neat, but the weight is large, generally up to 1000 kg per linear meter, and mechanical lifting is required, which is very inconvenient for construction. If cast-in-place side ditches are used, the surface of the side ditches cannot be guaranteed to be clean and beautiful due to the template.

[0003] Therefore, how to make the type and construction form of the side ditch both convenient for construction and neat and beautiful has become a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0004] In view of the above-mentioned defects of the prior art, the utility model provides a multi-crack drainage ditch structure combining a prefabricated cover plate with a cast-in-place ditch body, the purpose of which is to maximize the use of the limited space within the road red line while meeting the requirements of road drainage and curbstones, making the construction faster and more convenient while ensuring a neat appearance.

[0005] To achieve the above purpose, the utility model discloses a multi-crack drainage ditch structure combining a prefabricated cover plate and a cast-in-place ditch body, including a cast-in-place ditch body arranged between a sidewalk and a roadway; the sidewalk is an upper street edge located on one side of the roadway.

[0006] The cast-in-place ditch body is a strip structure with a "concave"-shaped cross section extending along the sidewalk close to one side of the carriageway, and a plurality of prefabricated cover plates are arranged at the upper opening along the length direction. There is a height difference between the upper end of the sidewalk side wall close to the sidewalk and the upper surface of the sidewalk that matches the thickness of the corresponding position of the prefabricated cover plate, and the upper end of the lane side wall close to the carriageway is flush with the carriageway;

[0007] Each of the prefabricated cover plates is L-shaped in the cross section of the cast-in-place ditch body, and includes a flat plate structure parallel to the upper surface of the sidewalk at the corresponding position, and a longitudinal plate structure arranged between the flat plate structure and the upper end of the side wall of the lane;

[0008] A side surface of each of the flat plate structures connected to another adjacent flat plate structure is provided with an inwardly recessed inter-cover plate gap at a position between the side wall of the sidewalk and the side wall of the lane;

[0009] A downwardly extending footing structure is provided on the lower end surface of each longitudinal plate structure facing the lane side wall, and a gap between the cover plate and the ditch body is formed between the corresponding longitudinal plate structure and the lane side wall.

[0010] Preferably, a limiting block is provided under each of the prefabricated cover plates at a position corresponding to the inner side surface of the sidewalk side wall and the lane side wall.

[0011] More preferably, the size of each of the footrest structures corresponding to the width position of the lane side wall is greater than the width of the lane side wall;

[0012] All the limit blocks corresponding to the inner side of the lane side wall under each prefabricated cover plate are arranged under the pad structure.

[0013] Preferably, the ridge between the upper surface of each of the flat plate structures and a side of the corresponding longitudinal plate structure facing the roadway is a rounded structure.

[0022] Example

[0023] like Figures 1 to 4 As shown, the multi-crack drainage ditch structure combining a prefabricated cover plate and a cast-in-place ditch body includes a cast-in-place ditch body 1 arranged between a sidewalk 9 and a road 8; the sidewalk 9 is an upper street edge located on one side of the road 8.

[0024] The cast-in-place ditch body 1 is a strip structure with a "concave"-shaped cross section extending along the sidewalk 9 close to the side of the roadway 8. A plurality of prefabricated cover plates 2 are arranged at the upper opening along the length direction. There is a height difference between the upper end of the sidewalk side wall 11 close to the sidewalk 9 and the upper surface of the sidewalk 9 that matches the thickness of the corresponding position of the corresponding prefabricated cover plate 2. The upper end of the lane side wall 12 close to the side of the roadway 8 is flush with the roadway 8.

[0025] Each prefabricated cover plate 2 is L-shaped in the cross section of the cast-in-place trench body 1, and includes a flat plate structure 21 parallel to the upper surface of the sidewalk 9 at the corresponding position, and a longitudinal plate structure 22 arranged between the flat plate structure 21 and the upper end of the side wall 12 on the side of the lane;

[0026] On the side where each flat plate structure 21 is connected to another adjacent flat plate structure 21, an inwardly concave inter-cover plate gap 211 is provided at a position between the sidewalk side wall 11 and the lane side wall 12;

[0027] A downwardly extending footing structure 221 is provided on the lower end surface of each longitudinal plate structure 22 facing the lane side wall 12 , and a gap 222 between the cover plate and the ditch body is formed between the corresponding longitudinal plate structure 22 and the lane side wall 12 .

[0028] The utility model directly places a prefabricated cover plate 2 on the cast-in-place ditch body 1, and uses the crack 222 between the cover plate and the ditch body and the crack 211 between each two prefabricated cover plates 2 to drain water. The overall structure is simple, practical and economical.

[0029] Preferably, a limiting block 23 is provided under each prefabricated cover plate 2 at a position corresponding to the inner side surface of the sidewalk side wall 11 and the lane side wall 12 .

[0030] More preferably, the size of each footing structure 221 at the width position corresponding to the corresponding lane side wall 12 is greater than the width of the lane side wall 12;

[0031] All the limiting blocks 23 on the inner side of the side wall 12 on the lane side under each prefabricated cover plate 2 are arranged under the pad structure 221 .

[0032] Preferably, the ridge between the upper surface of each flat plate structure 21 and the side of the corresponding longitudinal plate structure 22 facing the roadway 8 is a rounded structure.

[0033] In practical applications, the radius of the rounded structure is 20 mm.

[0034] Preferably, the size of each crack 211 between the cover plates is 15 mm×200 mm; the size of each crack 222 between the cover plates and the groove body is 300 mm×15 mm.

[0035] The utility model directly places the prefabricated cover plate 2 on the cast-in-place ditch body 1, thereby making it easier to control the construction quality and improving the convenience of the engineering construction.

[0036] The utility model drains water through the cracks 222 between the prefabricated cover plate 2 and the cast-in-place ditch body 1 and the cracks 211 between the prefabricated cover plate 2 and the adjacent prefabricated cover plate 2, thereby enhancing the road surface drainage effect.

[0037] The edges of the prefabricated cover plate 2 of the present invention close to the roadway 8 are rounded with a radius of 20 mm to achieve the effect of a curbstone, maximize the use of the limited space within the road red line, and meet the road function to the greatest extent.

[0038] Of course, any product implementing the present invention does not necessarily need to achieve all of the above advantages at the same time.
