Description

Technical Field

[0001] The utility model belongs to the technical field of drainage systems and relates to a drainage structure used for drainage of a large square. Background Art

[0002] In recent years, there are more and more cargo warehousing and logistics projects in industrial parks. The raw material and finished product loading and unloading squares are characterized by a large number of vehicles, large shipping volume and concentrated traffic. The squares are required to be as spacious and flat as possible to ensure the safety of vehicle driving.

[0003] With the increasing frequency of extreme weather and rainfall, higher requirements are being placed on the drainage of loading and unloading plazas for cargo storage and logistics projects in industrial parks. Standardized drainage systems can effectively prevent water accumulation in plazas and protect buildings and facilities from flooding. The slope directly affects the flow rate and drainage effectiveness of water. Generally speaking, the steeper the slope, the faster the water flow and the better the drainage effect.

[0004] Conventional loading and unloading plaza drainage primarily utilizes the plaza's slope, connecting to the plaza's perimeter drainage system. Considering the need for vehicle access and safe parking, the ideal slope for loading and unloading plazas is between 0.5% and 1.0%.

[0005] Therefore, for large-scale raw material and finished product loading and unloading areas with numerous vehicles, large shipping volumes, and concentrated traffic, the slope of the area should be minimized for vehicle safety and increased for drainage. Obviously, conventional methods are unlikely to meet drainage requirements. Utility Model Content

[0006] The purpose of the utility model is to provide a drainage structure for large-area squares, so as to solve the technical problem that it is difficult to set a reasonable square slope in the prior art while ensuring vehicle driving safety and effective square drainage.

[0007] The drainage structure for drainage of a large-area square includes a drainage ditch arranged on the large-area square, the drainage ditch divides the large-area square into at least two sections along the drainage direction of the square, the drainage ditch is connected to the square side ditch at the edge of the large-area square, the top perimeter of the drainage ditch is reinforced and constructed synchronously with the square floor and cast as a whole, the drainage ditch is provided with a number of drainage outlets along its own extension direction, and the main body of the drainage ditch is located below the square pavement.

[0008] Preferably, the drainage ditch includes a ditch body, a reinforced concrete pavement and a ditch concrete foundation. The ditch body is arranged on the ditch concrete foundation. The reinforced concrete pavement is arranged on both sides of the top of the ditch body. The top pavement of the reinforced concrete pavement is inclined downward toward the drainage ditch to form a certain slope. The reinforced concrete pavement and the ditch body are cast as a whole.

[0009] Preferably, the drain outlet is arranged at the top of the culvert body, adjacent drain outlets are spaced equally apart, and the drain outlet is covered with a cover plate.

[0010] Preferably, the cover plate is a heavy cast iron grille or a concrete grate plate.

[0011] Preferably, when the cover plate is a concrete grate, edge guards are provided on both sides of the top of the concrete grate plate along the width direction, and the edge guards are made of angle irons.

[0012] Preferably, the reinforced concrete pavement is connected to the pavement of the large square by embedded force transmission rods.

[0013] Preferably, the drainage ditch is divided into several sections along its own extension direction, and a water stop is provided at the connection between two adjacent sections of the drainage ditch.

[0014] Preferably, the slope of each section of the large-area square is 0.5%-1.0%, and the slope of the top road surface of the reinforced concrete pavement is 1.0%.

[0015] The utility model has the following advantages: the utility model sets the drainage ditch in the middle of the square, so that the slope of the large-area square can be controlled at 0.5%-1.0%, and still maintain a good drainage effect. The part of the square farther away from the hardened boundary line can drain water into the drainage ditch, so timely drainage can be achieved. The drainage ditch is connected to the side ditch of the square and the slope can be set as needed without being affected by the slope requirements of the square. Therefore, it can effectively drain water, thereby meeting the needs of setting a reasonable square slope for a large-area square while ensuring vehicle driving safety and effective drainage of the square.

[0016] The concrete drainage ditch and loading and unloading plaza floor are cast integrally, with reinforcement around the top of the ditch and a waterstop installed to ensure a tight seal, minimizing the risk of water seepage in the plaza's roadbed and extending its service life. The integration of the concrete drainage ditch and loading and unloading plaza provides a more concealed structure and ensures vehicle safety. Both the concrete drainage ditch and floor are convenient to construct, eliminating the need for complex construction. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following is a further detailed description of the specific implementation methods of the present invention by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0026] like Figure 1-Figure 7 As shown, the present invention provides a drainage structure for draining a large square, including a drainage ditch 4 provided on the large square 2. The drainage ditch 4 divides the large square 2 into at least two sections along the drainage direction of the square. The drainage ditch 4 is connected to the square side ditch at the edge of the large square 2. The top perimeter of the drainage ditch 4 is reinforced and constructed simultaneously with the square floor and cast as a whole. The drainage ditch 4 has several drainage outlets arranged along its extension direction. The ditch body 41 of the drainage ditch 4 is located below the square pavement. The width of the large square 2 along the drainage direction is not less than 20 meters. The slope of each section of the large square 2 is 0.5%-1.0%, and the slope of the top surface of the reinforced concrete pavement 43 is 1.0%. The square side ditch is provided at the hardened boundary line 3 of the large square 2.

[0027] For example, in the loading and unloading areas of this embodiment, the distance from building 1 to the hardened boundary line 3 is the drainage direction, and the distance between the two is the width along the drainage direction. When the width is not less than 20 meters and the slope is small, it is easy to cause poor drainage. In the loading area, building 1 is located in the center of a large square 2, and the square drainage direction is oriented towards the surrounding areas of the large square 2. Therefore, drainage culverts 4 are set up around building 1, and the four drainage culverts 4 are interconnected in a rectangular shape and ultimately connected to the square side gutter. In the unloading area, the large square 2 is located on one side of the building 1. When the width of the large square 2 along the drainage direction is not less than 20 meters, the drainage culverts 4 are set between the exit of building 1 and the hardened boundary line 3 opposite the exit. The direction of the square side gutter is the same as the square drainage direction, and the drainage culverts 4 are perpendicular to and connected to the square side gutter.

[0028] The drainage culvert 4 includes a culvert body 41, a reinforced concrete pavement 43, and a culvert concrete foundation 42. The culvert body 41 is installed on the culvert concrete foundation 42. The reinforced concrete pavement 43 is installed on both sides of the top of the culvert body 41. The top of the reinforced concrete pavement 43 is inclined downward toward the drainage culvert 4 to form a certain slope. The reinforced concrete pavement 43 and the culvert body 41 are integrally cast. The culvert concrete foundation 42 uses C20 concrete.

[0029] The drain outlets are provided at the top of the culvert body 41, and the intervals between adjacent drain outlets are equal. In this embodiment, the interval between drain outlets is 10 meters. The drain outlets are covered with a cover plate.

[0030] The cover plate is a heavy cast iron grille or a concrete grating 44. In this embodiment, the concrete grating 44 is used, and the concrete grating 44 is provided with a plurality of elongated through slots 441, which are evenly arranged along the width of the concrete grating 44. The top side of the concrete grating 44 is provided with a side guard 45, which is made of angle iron.

[0031] The cross section of the culvert body 41 is a hollow rectangle and is a reinforced concrete structure. The reinforced concrete pavement 43 is connected to the pavement of the large square 2 via an embedded force transmission rod 48 .

[0032] The drainage ditch 4 is divided into several sections along its own extension direction. A waterstop is provided at the connection between two adjacent sections of the drainage ditch 4. In this embodiment, the outer edge of the connection is fully covered with an external rubber waterstop 46, and the inner edge of the connection is provided with an embedded steel plate waterstop 47. Two layers of hot asphalt 49 are provided on the outer surface of the ditch.

[0033] The construction process of the present invention includes: first calculating the size of the large-area square 2, then completing the plane and slope design of the concrete drainage ditch 4, compacting the square roadbed and finding the slope, synchronously constructing the drainage ditch 4 and the square floor, and pouring the two as a whole, performing concrete curing, and finally installing the concrete grating 44 to the drainage outlet at the top of the drainage ditch 4.

[0034] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the inventive concept and technical solution of the present invention, or the inventive concept and technical solution are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
