[0002] In the operation of bulk cargo port, the storage of bulk cargo such as iron ore, coal and the like is usually carried out in open yard, and the drainage design of these yards is a key factor to ensure the quality of goods and the safety of operation. The traditional drainage method relies on the natural permeability of bulk cargo and the passive drainage system of the yard surface, for example, by laying hardening materials such as interlocking blocks or concrete slabs on the surface of the yard to form a certain slope, so that rainwater can flow along the surface of the material pile or penetrate into the surface layer of the yard, and finally flow into the drainage ditch for collection and discharge. Although this method can effectively drain water to some extent, its drainage efficiency and capacity are limited by the permeation speed of bulk cargo and the drainage slope of the yard, and it is often difficult to quickly reduce the moisture content of the material pile, especially after heavy rainfall, the water in the material pile cannot be quickly discharged, which causes the bulk cargo to easily form a slurry state, not only affecting the loading and unloading efficiency, but also possibly causing adverse effects on the environment and the quality of goods. In addition, the construction cost of the hardening surface layer is high, and the maintenance and updating also require additional costs, and in some cases, the hardening surface layer may hinder the natural penetration of water, thereby reducing the drainage efficiency.

DETAILED DESCRIPTION

[0021] It should be noted that the embodiments and the features in the embodiments in the present application can be combined with each other without conflict.

[0022] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0023] In the present application, unless otherwise stated, the orientation words such as "up, down, top, bottom" are generally directed to the direction shown in the drawings, or directed to the vertical, perpendicular or gravity direction of the components themselves; similarly, for the convenience of understanding and description, "inner, outer" refers to the inner and outer of the contour of each component itself, but the above orientation words are not used to limit the present application.

[0024] Obviously, the above-described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.

[0025] In order to solve the problem of poor drainage effect of bulk cargo port yard in rainy days in the prior art, the utility model provides a yard drainage system.

[0026] As Figure 1 The yard drainage system includes a sedimentation pool 10, a filter layer 20 and a drainage pipeline 30. The central area of the bottom of the sedimentation pool 10 is raised upward to form a guide structure 11. The filter layer 20 is arranged above the guide structure 11, and the filter layer 20 is used to place goods 100 to filter the accumulated water in the goods 100. The drainage pipeline 30 is arranged at the bottom of the sedimentation pool 10 to drain the accumulated water.

[0027] The guiding structure 11 is formed by bulging the bottom of the sediment pool 10 upward, and the filter layer 20 is laid, and the goods 100 are arranged on the filter layer 20. When it rains, the rainwater entering the goods 100 gradually sinks downward under the influence of gravity and finally reaches the sediment pool 10 through the filter layer 20. The rainwater converges to the two ends of the bottom of the sediment pool 10 under the guiding action of the guiding structure 11, and the accumulated water is sucked out of the sediment pool 10 by the drain pipe 30, thereby avoiding the corrosion and damage of the goods 100 caused by the accumulation of rainwater at the bottom of the goods 100, and improving the drainage effect of the freight yard. At the same time, when the freight yard encounters continuous rainfall, the accumulated water can be quickly guided to the drain pipe 30, effectively preventing the goods 100 from being soaked in water, reducing the loss of the goods 100, and also avoiding the operation interruption of the freight yard caused by the accumulated water, ensuring the continuity of logistics.

[0028] As shown in Figure 1 The freight yard drainage system further comprises a waterproof layer 40, and the waterproof layer 40 is arranged at least on the surface of the guiding structure 11. The waterproof layer 40 is used to separate the guiding structure 11 and the accumulated water.

[0029] Specifically, the bottom of the guiding structure 11 is the same as the bottom of the entire sediment pool 10, and the waterproof layer 40 is wrapped on the entire guiding structure 11. The rainwater filtered through the filter layer 20 flows downward along the axial direction of the guiding structure 11. The arrangement of the waterproof layer 40 can separate the rainwater and the guiding structure 11 to avoid the rainwater from penetrating into the guiding structure 11 and causing the strength of the guiding structure 11 to decrease.

[0030] In another embodiment of the present application which is not shown in the figure, the size of the bottom of the guiding structure 11 is smaller than the size of the bottom of the sediment pool 10, and the waterproof layer 40 is arranged at the bottom of the guiding structure 11 and the sediment pool 10. Of course, the waterproof layer 40 can be arranged only on the guiding structure 11, and the bottom of the sediment pool 10 is provided with a waterproof board or a waterproof layer.

[0031] In the embodiment, the waterproof layer 40 is an integral impermeable geotextile.

[0032] In the embodiment, the guiding structure 11 is matched with the bottom of the sediment pool 10, and the cross section of the guiding structure 11 is trapezoidal.

[0033] Specifically, the size of the bottom of the guiding structure 11 is the same as the size of the bottom of the sediment pool 10, and the rainwater can move downward from the top of the sediment pool 10 along the guiding structure 11 and gradually reach the two ends of the bottom of the sediment pool 10. The guiding structure 11 arranged in a trapezoidal shape can ensure the structural strength of the top of the guiding structure 11. The guiding structure 11 with a trapezoidal cross section can still maintain stability under the heavy pressure of the goods 100 and is not easy to deform, thereby ensuring the long-term effectiveness of the drainage system.

[0034] In this embodiment, the drainage pipe 30 is disposed between the waterproof layer 40 and the filter layer 20 . There are two drainage pipes 30 , and the two drainage pipes 30 are disposed on both sides of the guide structure 11 .

[0035] Specifically, the drainage pipes 30 are provided at both ends of the sedimentation tank 10, respectively for collecting the accumulated water on both sides of the guide structure 11. Optionally, the drainage pipes 30 are provided in a direction parallel to the bottom of the sedimentation tank 10. Alternatively, the drainage pipes 30 are provided with multiple water inlets to facilitate the collection of accumulated water.

[0036] In this embodiment, the drainage pipe 30 is made of a steel pipe or a material with a certain structural strength. Optionally, a groove is provided at the bottom of the sedimentation tank 10, and the structure of the groove is adapted to the drainage pipe 30.

[0037] like Figure 1 As shown, the filter layer 20 includes a first filter layer 21 and a second filter layer 22. The top surface of the first filter layer 21 is flush with the top of the sedimentation tank 10. The second filter layer 22 is disposed below the first filter layer 21, and the guide structure 11 extends into the second filter layer 22.

[0038] Specifically, the first filter layer 21 and the second filter layer 22 are arranged in a vertical sequence. This arrangement allows rainwater to enter the sedimentation tank 10 while intercepting dirt and other debris on the ground. The guide structure 11 divides the entire second filter layer 22 into two parts. The multi-layer filter layer 20 effectively filters impurities from the cargo 100 and keeps the drainage pipe 30 unobstructed. For cargo yards carrying large quantities of bulk goods 100, such as fertilizer, this prevents impurities from clogging the drainage pipe 30, maintaining a clean and efficient drainage system.

[0039] In this embodiment, the first filter layer 21 is a medium-coarse sand layer, and the second filter layer 22 is a gravel layer.

[0040] Specifically, the different types of filter layers 20 are arranged in the sedimentation tank 10 to improve the filtering effect, and the pore size of the first filter layer 21 is smaller than that of the second filter layer 22. When the first filter layer 21 filters rainwater, due to the friction and occlusion between the sand particles, the medium-coarse sand layer can provide certain anti-seepage and filtering effects while maintaining water permeability, preventing finer particles from being lost with the water flow. The pores between the gravel layers are also relatively large, which makes the gravel layer have good water permeability and air permeability, enabling rapid drainage, and also providing certain structural support. The combination of the gravel layer and the medium-coarse sand layer can ensure the drainage effect while avoiding the sinking of the filter layer 20 due to the heavy weight of the goods 100 and the loss of small-volume goods 100. For example, when the goods 100 are coal mines, due to the anti-seepage performance of the medium-coarse sand layer, the loss of small-volume coal mines is avoided, the loss of goods 100 stored in the goods yard when encountering rainy weather is reduced, and the user's satisfaction is improved.

[0041] As shown in Figure 2 , the side wall 12 of the sedimentation tank 10 is provided with a drainage structure 50, and the drainage structure 50 is arranged at least at the bottom of the side wall 12. The drainage structure 50 is matched with the drainage pipeline 30.

[0042] Specifically, the drainage structure 50 is arranged at the position of the drainage pipeline 30. When it rains heavily, the drainage pipeline 30 cannot discharge the accumulated water in time or with low efficiency, and the drainage structure 50 can cooperate with the drainage pipeline 30 to discharge water, thereby improving the drainage effect of the goods yard. For the goods yard close to the river, the arrangement of the drainage structure 50 on the side wall 12 is an effective measure to deal with extreme weather such as heavy rain and flood. It can quickly discharge the accumulated water and prevent the goods yard from being flooded, thereby ensuring the normal operation of the goods yard and reducing economic losses caused by natural factors.

[0043] As shown in Figure 2 , the drainage structure 50 includes a plurality of drainage holes 51.

[0044] Specifically, the drainage holes 51 are circular, and the diameter of the drainage holes 51 is smaller than the size of the gravel in the second filter layer 22, so as to avoid the gravel from being stuck in the drainage holes 51. The arrangement of the plurality of drainage holes 51 can avoid the complete blockage of one of the drainage holes 51 by large-volume gravel, and the drainage holes 51 can still complete the drainage operation.

[0045] In this embodiment, the drainage structure 50 is integrally formed with the side wall 12 or detachably connected with the side wall 12.

[0046] Specifically, the yard drainage system further comprises a drainage groove 70. When the drainage structure 50 is integrally formed with the side wall 12, the drainage groove 70 is excavated at the same time when the drainage hole 51 is formed in the side wall 12, and the accumulated water can enter the drainage groove 70 through the drainage hole 51. When the drainage structure 50 is detachably connected with the side wall 12, the drainage groove 70 is pre-formed in the bottom of the side wall 12. The drainage structure 50 comprises a mounting plate 52 and a drainage hole 51 formed in the mounting plate 52. A plurality of drainage holes 51 are arranged in an array on the mounting plate 52. The mounting plate 52 is sized to fit the drainage groove 70. This arrangement facilitates construction. Optionally, the drainage groove 70 is arranged to be inclined downward along a direction parallel to the bottom surface of the sedimentation pool 10. The outlet of the drainage groove 70 is located above the river or above the sea, so that the water in the drainage groove 70 is drained to the river or the sea along the drainage groove 70. Due to the arrangement of the first filter layer 21 and the second filter layer 22, and the anti-seepage effect of the medium-coarse sand layer of the first filter layer 21, the accumulated water drained from the drainage groove 70 does not contain other impurities and does not pollute the river or the sea. Optionally, the bottom of the sedimentation pool 10 is also provided with a drainage structure 50. At this time, the drainage groove 70 is formed in the bottom of the sedimentation pool 10 and the side wall 12.

[0047] In the embodiment, the yard drainage system further comprises a water pump 60. The water pump 60 is in communication with the drainage pipeline 30 and is used to pump out the accumulated water.

[0048] Specifically, the water pump 60 is arranged on both sides of the sedimentation pool 10. Two water pumps 60 are respectively in communication with two drainage pipelines 30 to realize drainage.

[0049] In the embodiment, the water pump 60 is also in communication with the drainage groove 70. The water pump 60 is used to simultaneously pump out the accumulated water in the drainage pipeline 30 and the drainage groove 70.

[0050] The construction process of the technical scheme of the present application is as follows: Step one, select a yard, and perform foundation treatment according to the geological conditions and external load of the yard; Step two, excavate the sedimentation pool 10 of the yard. The depth of the sedimentation pool 10 is 1.5-2m, and a guide structure 11 is formed in the sedimentation pool 10; Step three, install a drainage pipeline 30 at the bottom of the sedimentation pool 10; Step four, install a water pump 60, set a drainage structure 50 and a drainage groove 70; Step five, lay a waterproof layer 40, a first filter layer 21 and a second filter layer 22; Step six, debug the water pump 60.
