Abstract
Description
Technical Field
[0001] The utility model relates to the field of airport engineering, in particular to an apron drainage ditch structure. Background Art
[0002] Common drainage structures on airport aprons include cast iron grate box culverts and cast iron grate open ditches. The disadvantage of cast iron grate box culverts is that the opening rate is small, and the effective opening area is only the drainage holes and the grate. The surface water collection effect is affected by the direction and spacing of the drainage holes. In extreme weather, it is often too late to collect water, causing water accumulation on the apron. Especially when used as an intercepting ditch, the water interception effect is not good, which will invisibly increase the confluence area of the drainage ditch on the same side and exceed the original design capacity. The disadvantages of cast iron grate open ditches are firstly that the ditch width is small, and the water delivery section cannot meet the needs of a large area of aprons; secondly, the cast iron grates fixed on the box culvert are prone to bolt loosening under the repeated action of the aircraft landing gear wheel load, causing large displacement and deformation of the grates, leading to safety hazards, and thus increasing the workload of daily maintenance; in addition, due to the lack of integrity of this ditch body, it often causes large deformation under the action of pavement top expansion, causing serious damage. Utility Model Content
[0003] The utility model aims to provide an apron drainage ditch structure to solve the technical problems of poor water interception effect and low rainwater collection efficiency of drainage structures in the prior art.
[0004] To achieve the above-mentioned purpose, the utility model provides an apron drainage ditch structure, including a ditch body, wherein a drainage channel extending along a water conveyance direction is provided in the ditch body, and a first drainage hole is provided on the upper surface of the ditch body, and the first drainage hole extends from the upper surface in the depth direction to be connected with the drainage channel, and rainwater flows on the upper surface of the ditch body along the water flow direction and enters the drainage channel through the first drainage hole; the first drainage hole extends along its length direction to form a slender structure, wherein the length direction is perpendicular to the water flow direction.
[0005] Compared with the prior art, the beneficial effects of the present invention are:
[0006] The apron drainage ditch structure of the utility model is provided with a first drainage hole on the upper surface of the ditch body, and the first drainage hole is set to extend along its length direction to form a slender structure, so that the length direction is perpendicular to the water flow direction, thereby the front area of the upper edge of the drainage hole facing the flowing rainwater is larger, forming a greater water interception resistance to the water flow, which is conducive to promoting the stagnation of rainwater and falling into the drainage channel through the first drainage hole, thereby realizing efficient collection of rainwater.
[0007] Preferably, a second drainage hole is further provided on the upper surface of the ditch body, and the second drainage hole extends from the upper surface in the depth direction to communicate with the drainage channel, a water grate is provided in the second drainage hole, and the width of the second drainage hole is smaller than the width of the drainage channel.
[0008] Preferably, a plurality of the first drainage holes are arranged at intervals end to end in the length direction to form a drainage hole belt.
[0009] Preferably, the apron drainage ditch structure is provided with a plurality of drainage hole belts in the width direction of the drainage channel.
[0010] Preferably, the drainage channel is provided with a chamfer.
[0011] Preferably, the water delivery direction is parallel to the length direction of the first drainage hole. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] Embodiment 1:
[0021] Figure 1 The schematic diagram of the structure of the apron drainage ditch provided by the utility model is as follows: Figure 2a for Figure 1 AA section diagram of the drainage ditch structure in the middle apron. Figure 1 and Figure 2a As shown, this embodiment discloses an apron drainage ditch structure, including a ditch body 1, in which a drainage channel 2 extending along the water conveying direction is provided. A first drainage hole 3 is provided on the upper surface of the ditch body 1, and the first drainage hole 3 extends from the upper surface in the depth direction to communicate with the drainage channel 2, and rainwater flows along the water flow direction on the upper surface of the ditch body 1 and enters the drainage channel 2 through the first drainage hole 3. Expansion joints 5 are provided on both sides of the ditch body 1 in the length direction.
[0022] like Figure 1 As shown, the first drainage hole 3 extends along its length direction to form a slender structure, wherein the length direction is perpendicular to the water flow direction, so that the upper edge of the drainage hole faces a larger area of the flowing rainwater, thereby forming a greater water interception resistance to the water flow, which is conducive to promoting the stagnation of rainwater and falling into the drainage channel through the first drainage hole, thereby realizing efficient collection of rainwater.
[0023] In some preferred embodiments, the water delivery direction is parallel to the length direction of the first drainage hole 3, which is conducive to rapid drainage of rainwater after entering the drainage channel through the first drainage hole.
[0024] Figure 2b for Figure 1 BB section diagram of the drainage ditch structure in the middle apron. Figure 2b As shown, the upper surface of the ditch body 1 is also provided with a second drainage hole 4, which extends from the upper surface in the depth direction to be connected with the drainage channel 2. A drainage grate 41 is provided in the second drainage hole 4. The width of the second drainage hole 4 is smaller than the width of the drainage channel 2. The drainage grate thus arranged can resist the top expansion effect of the road panel due to the integral box culvert structure, and can prevent the drainage grate from undergoing large deformation.
[0025] Specifically, the plurality of first drainage holes 3 are arranged at intervals in the longitudinal direction to form a drainage hole belt. More specifically, in this embodiment, the apron drainage ditch structure is provided with two drainage hole belts in the width direction of the drainage channel 2.
