Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building engineering construction, especially relates to a micro drainage ditch cover plate. BACKGROUND

[0002] In the field of building engineering construction, the material storage area of large-area concrete site is above 10000 square meters, and a high-efficiency drainage system and reasonable planning of drainage ditch arrangement are needed to ensure the dryness and safety of the construction site and prevent construction delay or safety accidents caused by accumulated water. The traditional drainage method is to set an open drainage ditch along the four sides of the material storage area, but this drainage ditch has the technical problems of being easily blocked by debris without a cover plate, difficult to maintain, and low drainage efficiency.

[0003] After searching, a utility model patent drainage ditch cover plate and drainage ditch, application number 202021171175.6, application date June 22, 2020, authorization announcement date March 12, 2021, the utility model drainage ditch cover plate and drainage ditch provide a drainage ditch cover plate and drainage ditch with simple structure, convenient construction, safety and reliability, which can solve the problem of open drainage ditch without cover plate being easily blocked by debris, but the utility model drainage ditch cover plate and drainage ditch have the technical problems of being difficult to maintain, inconvenient to transport and turnover, and the technical problems of open drainage ditch maintenance difficulty and low drainage efficiency are still not solved. UTILITY MODEL CONTENT

[0004] In view of the deficiencies of the prior art, the technical problem solved by the utility model is to provide a micro drainage ditch cover plate to solve the technical problems of low drainage efficiency of the existing drainage ditch, difficult maintenance of the drainage ditch cover plate, and inconvenient transportation and turnover.

[0005] In order to solve the above problems, the utility model adopts the technical scheme of: a micro drainage ditch cover plate, the drainage ditch cover plate has a support structure and a panel structure, the lower end of the support structure is fixed with a pad, when the pad is supported on the bottom of the drainage ditch, the upper surface of the panel structure at the upper end of the support structure is flush with the road surface on both sides of the drainage ditch, and the panel structure is fixed on the upper end of the support structure through a hinge device. The drainage ditch is provided with the drainage ditch cover plate in the drainage ditch groove, and the drainage ditch cover plate is supported on the bottom surface of the drainage ditch groove through the support structure.

[0006] Further, the panel structure is made of a steel plate with a width of 200mm and a thickness of more than 6mm and less than 12mm. The steel plate with a thickness of more than 6mm and less than 12mm can withstand the load on the construction site, including the pressure caused by construction vehicles, equipment and personnel walking, and ensure that the drainage ditch cover plate does not deform or damage during use.

[0007] Further, the steel plate is uniformly provided with 4 drainage holes with a diameter of 6-10 mm in the cross-sectional direction; and the cross-sectional layout of the holes is repeated every 100-200 mm in the longitudinal direction of the steel plate. The holes in the steel plate help to drain rainwater, prevent water accumulation, and facilitate on-site personnel to check the state of the drainage ditch through the holes and timely find and solve problems.

[0008] Further, the drainage holes have the same diameter and spacing on the same cover plate. When the diameter and spacing of the drainage holes are consistent, the stress acting on the cover plate can be more evenly distributed, avoiding deformation or damage of the cover plate due to local stress concentration.

[0009] Further, the support structure is composed of a steel bar and a pad, the diameter of the steel bar is above 8 mm and below 22 mm, the pad is processed from a steel plate, the size of the pad is 3 times the diameter of the steel bar, and the steel bar is welded at the center position of the pad. The steel bar as a support increases the bending resistance of the steel plate, making it less likely to bend under external force. The pad increases the stress area of the support structure, making the support structure more stable.

[0010] Further, the panel structure and the support structure are connected through a hinge device, so that the support structure can rotate relative to the longitudinal direction of the panel structure. When the support structure rotates to a position parallel to the panel structure, the occupied space of the drainage ditch cover plate is reduced, facilitating the transportation and turnover of the drainage ditch cover plate on the construction site. When the support structure rotates to a position perpendicular to the panel structure, the support structure supports the panel structure, increasing the stability and load-bearing capacity of the entire drainage ditch cover plate.

[0011] Further, the drainage ditch adopts a grid layout with a longitudinal spacing and a transverse spacing of 6 m and a drainage ditch width of 200 mm. The drainage ditch layout reduces the water flow path, improves the drainage speed, and solves the technical problem of low drainage efficiency.

[0012] The beneficial effects of the technical solution are:

[0013] 1. The drainage ditch cover plate is mainly made of leftover materials on the construction site, saving costs and fully utilizing resources.

[0014] 2. The drainage ditch cover plate has a support structure and a panel structure, and the support structure rotates relative to the panel structure through a hinge device. When the support structure rotates to a position parallel to the panel structure, the occupied space of the drainage ditch cover plate is reduced, facilitating the transportation and turnover of the drainage ditch cover plate on the construction site.

[0015] 3. The drainage ditch adopts a grid layout, the longitudinal interval and the transverse interval are both 6m, and the drainage ditch width is 200mm. The drainage ditch layout reduces the water flow path, improves the drainage speed, and solves the technical problem of low drainage efficiency. BRIEF DESCRIPTION OF DRAWINGS

[0020] The following is further described in detail through specific embodiments:

[0021] In combination Figure 1 The utility model discloses a drainage ditch cover plate, drainage ditch cover plate includes support structure and panel structure, the support structure includes reinforcing bar 2, cushion block 4, the cushion block 4 is fixed in reinforcing bar lower end and plays the role of stabilizing, the panel structure is fixed on the upper end of support structure through hinged device.

[0022] In combination Figure 2 The utility model discloses a drainage ditch 5, drainage ditch 5 width is 200mm, and drainage ditch is arranged according to the grid, and the longitudinal interval and the transverse interval are both 6 meters.

[0023] Firstly, the remaining steel plate 1 and reinforcing bar 2 after the construction on site are collected, the steel plate 1 requires that the thickness is above 6mm and below 12mm, and the reinforcing bar 2 requires that the diameter is above 8mm and below 22mm. If the thickness of the steel plate 1 is less than 6mm, the steel plate 1 will not be able to bear the load on the construction site, and if the thickness of the steel plate 1 is greater than 12mm, the self-weight of the drainage ditch cover plate will be increased, and it is inconvenient to carry and circulate. If the diameter of the reinforcing bar 2 is less than 8mm, the reinforcing bar 2 will not have enough bending resistance and will be easily bent, and thus the reinforcing bar 2 will not be able to effectively play a supporting role, and if the diameter of the reinforcing bar 2 is greater than 22mm, the self-weight of the drainage ditch cover plate will be increased, and it is inconvenient to carry and circulate.

[0024] Then, the steel plate 1 is processed by using a cutting device, the width of the steel plate 1 is 200mm after processing, and holes are opened on the steel plate 1 by using mechanical equipment, four drainage holes with a diameter of 8mm are evenly arranged along the cross-sectional direction of the steel plate 1, and the opening layout of the cross section is repeated every 100mm along the longitudinal direction of the steel plate 1.

[0025] Then the remaining steel plate 1 with length and width greater than 20mm is selected for reprocessing, and the remaining steel plate 1 is processed into a cuboid pad 4 with length and width of 20mm by using a cutting device.

[0026] Then one end of the reinforcing steel bar 2 is welded to the center position of the pad 4 to form the reinforcing steel bar 2 welded with the pad 4.

[0027] Finally, the steel plate 1 processed by cutting and opening and the reinforcing steel bar 2 welded with the pad 4 are hinged through the hinge 3, so that the reinforcing steel bar 2 welded with the pad 4 can rotate relatively along the longitudinal direction of the steel plate 1 processed by cutting and opening.
