Description

Technical Field

[0001] The present invention relates to the technical field of drainage, and particularly to a container yard drainage system and an implementation method thereof. Background Art

[0002] Container yards play an important role in the port transportation system, and their main functions are to load, unload, stack, and transfer containers. Since a large amount of goods are stored in the yard, an effective drainage system needs to be set up to prevent waterlogging in the yard caused by bad weather such as heavy rain, which will affect the safety of goods and the loading and unloading operations. Especially in the rainy season, if the drainage system is not reasonably designed, waterlogging and mud will appear in the port area, seriously affecting the normal operation of the port and the container loading and unloading efficiency. With the improvement of the green environmental protection requirements in the port transportation industry and the promotion of the concept of sustainable development, the drainage system design of container yards pays more attention to environmental protection and economy.

[0003] To prevent the ground RMG rail beam (the rail beam structure of the rail-mounted container crane) in the port terminal container yard from being soaked and eroded by rainwater, the drainage area is often divided into each block area according to the distribution of the rail beams, and each block area is used as a drainage area. In the prior art, the drainage methods for container yards mainly include one-way drainage and two-way drainage. For one-way drainage, a drainage ditch or drainage pipe is set on one side of the block area, and the two tracks are at different elevations; for two-way drainage, drainage ditches or drainage pipes are set on both sides of the block area for drainage, with the middle of the yard being the high point, and then a drainage ditch or drainage pipe is set to connect these two drainage ditches or drainage pipes. Both of these methods have many problems, such as: the drainage effect is unstable, especially because the yard area has been under heavy pressure for a long time, causing uneven settlement of the yard ground and forming a low-lying area in the middle of the yard, resulting in poor drainage and even rainwater backflow; the tracks are located at the low elevation points, and if the site drainage is not timely, it is easy to cause water accumulation on the tracks; the ability to resist extreme weather risks is poor; the cost of drainage facilities is high; and the later maintenance and management are inconvenient.

[0004] Chinese Patent Application CN110029718A (publication date: July 19, 2019) discloses a rainwater drainage structure for a sunken container yard in a sponge port area, including a container yard. A drainage ditch is opened in the middle of the container yard. The container yard includes tracks and track foundations symmetrically arranged on both sides of the drainage ditch for the operation and walking of rail-mounted gantry cranes, box corner foundations with horizontal upper surfaces arranged in parallel between the tracks and the drainage ditch, and port roads arranged outside the two tracks; the box corner foundations are perpendicular to the tracks; a sunken pavement is arranged between adjacent box corner foundations. Its purpose is to form a rainwater storage pool through the height difference between the sunken yard design and the port road for rainwater regulation, reduce the pressure on the rainwater pipes in the port area, reduce the cost of the drainage pipe network, and enhance the flood prevention and disaster reduction ability of the container port area, so as to solve the problems of high cost and easy water accumulation in the container yard drainage solution.

[0005] In the above prior art, a drainage open ditch is arranged in the middle of the container yard, and the drainage open ditch collects rainwater and discharges it into the port rainwater pipe network system. To a certain extent, it can solve the problem that in the currently commonly used drainage method, the track beam is located at a low elevation point and is prone to corrosion due to water accumulation, and the cost is relatively low. However, this system is too simple, the drainage efficiency is not high, and the long-term stability of the drainage system is not good. Therefore, the contradiction between efficient drainage and economic savings in the container yard in the prior art is still very prominent. Summary of the Invention

[0006] In view of this, the present invention provides a container yard drainage system and an implementation method. By optimizing the structural design of the drainage system and the slope direction of the site, the number of drainage ditches and rainwater wells is reduced, the project investment and maintenance costs are reduced, and while the drainage efficiency is improved, the later maintenance workload is reduced.

[0007] Aiming at the problems of low drainage efficiency, poor economy, and difficulty in later maintenance of the container yard drainage system in the prior art, the present invention provides a container yard drainage system and an implementation method.

[0008] A container yard drainage system, characterized in that: The drainage system includes: an uncovered drainage open ditch, a slit drainage ditch, a rainwater main pipe, a rainwater inlet, and a ditch pipe connection well; The ditch pipe connection well includes a first ditch pipe connection well and a second ditch pipe connection well.

[0009] The container yard includes multiple block areas, and each block area is symmetrically provided with tracks for the operation and walking of container cranes and RMG track beams, and a port road is arranged outside the container yard.

[0010] The uncovered drainage open ditch is arranged in the middle of the container yard, parallel to the RMG track beam, and is used to collect the surface runoff rainwater of each block area of the container yard. A rainwater inlet is arranged at the low point of the bottom of the uncovered drainage open ditch, and it is connected to the first ditch pipe connection well; The slit drainage ditch is arranged at the edge of the transverse road in the container yard and is used to collect the road surface rainwater. A rainwater inlet is arranged at the low point of the bottom of the ditch, and it is connected to the second ditch pipe connection well; The rainwater main pipe is laid perpendicular to the RMG track beam and communicates with the first ditch pipe connection well and the second ditch pipe connection well; Further, the uncovered drainage open ditch adopts a cast-in-place concrete process, the ditch wall is plastered with cement mortar, the intersection of the bottom of the ditch and the ditch wall is rounded, and the bottom of the ditch slopes uniformly towards the rainwater inlet; Further, the rainwater main pipe is installed 30 cm higher than the bottom of the ditch pipe connection well to prevent the sediment in the ditch pipe connection well from entering the rainwater main pipe; Furthermore, the widths and depths of the open drainage ditches without covers, the slit drainage ditches, the slit widths of the slit drainage ditches, and the pipe diameters of the rainwater main pipes are calculated based on the area of the collected rainwater and the local precipitation. Furthermore, the slit drainage ditches adopt precast components, which have strong load-bearing capacity and meet the requirements of the vehicle loads passing through the container yard of the wharf.

[0011] Furthermore, the longitudinal roads in the container yard slope towards both sides, and the rainwater on the road surface drains into the open drainage ditches without covers in the nearby container blocks.

[0012] Preferably, the cover plate of the second trench pipe connection well adopts a ductile iron cover plate or a steel grating cover plate, which can effectively avoid the erosion of the highly corrosive environment of the port wharf and effectively reduce the later maintenance cost.

[0013] The present invention also provides an implementation method of the above container yard drainage system, which is characterized in that: It includes the following steps: Step S1: An open drainage ditch without a cover is arranged at the transverse center line of each container block. The open drainage ditch without a cover is a local low point, and the ground on both sides slopes towards the open drainage ditch without a cover from the RMG track beam. Step S2: Slit drainage ditches are arranged at the edges of both sides of the transverse roads in the container yard. The center line of the road is the high point, and it slopes towards the slit drainage ditches along the transverse slope direction of the road. Step S3: A rainwater main pipe is vertically arranged perpendicular to the RMG track beam at a quarter of the distance from the end at both ends of each container block; the rainwater main pipe connects the first rainwater connection well and the second rainwater connection well.

[0014] Step S4: The rainwater in the rainwater main pipe is discharged into the port drainage pipe and discharged into the sea after treatment.

[0015] Compared with the prior art, the technical solution of the present application has the following advantages and effects: 1. Improve drainage efficiency: The two-way slope of the automated heavy container area towards the open drainage ditch without a cover at the center line enables the rainwater to quickly drain into the open drainage ditch without a cover in the container yard; the trench pipe connection wells are arranged at a quarter of the distance from the ends of the drainage ditches in the container yard and on the road, enabling the rainwater in the drainage ditches to be discharged to the trench pipe connection wells in the shortest path, significantly improving the drainage efficiency. 2. Simplify the construction process and save the construction period: The middle of the container yard adopts an open drainage ditch without a cover made of concrete, and the drainage ditches on the road adopt precast drainage pipes, optimizing the number of connection wells, making the construction process simpler and saving construction time. 3. Simplify maintenance management: By arranging the main drainage pipes within the container yard, vehicle rolling is reduced, effectively minimizing pipe damage. A drainage ditch is set in the middle of the container yard, with the low elevation point located in the drainage ditch, preventing poor drainage caused by uneven ground settlement in the later stage and effectively reducing the later maintenance cost. An uncovered open drainage ditch is set in the middle of the site, facilitating later cleaning, management, and maintenance. 4. Reduce environmental impact: A slit drainage ditch is adopted at the road edge, and the connection wells of the ditch pipes are arranged within the container area. This not only avoids being damaged by passing vehicles but also has little impact on the environmental visual effect. By adopting a more environmentally friendly and sustainable drainage method, the impact on the port area environment is reduced, meeting the current improvement of environmental awareness and the promotion of the concept of sustainable development. 5. Reduce project investment: By optimizing the drainage layout, the number of drainage ditches is reduced, further reducing the number of drainage structures such as rain inspection wells and ditch pipe wells. An uncovered open drainage ditch is used in the middle of the container yard, significantly reducing the upfront investment of the project.

[0024] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, those of ordinary skill in the art can make several improvements and modifications to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0025] Embodiment 1 This embodiment provides a drainage system for a container yard. The plan of the yard drainage system is as Figure 1 shown below, specifically as follows: The drainage system includes: an open drainage ditch without cover 2, a slit drainage ditch 3, a rainwater main pipe 4, a rainwater inlet 5, and a ditch pipe connection well 6; The ditch pipe connection well 6 includes a first ditch pipe connection well 61 and a second ditch pipe connection well 62.

[0026] The container yard 7 includes multiple block areas. Each block area is symmetrically provided with a track for the operation and travel of a container crane and an RMG track beam 1, and a port road 8 is provided outside the container yard 7.

[0027] The open drainage ditch without cover 2 is arranged in the middle of the container yard 7. The open drainage ditch without cover 2 is arranged parallel to the RMG track beam 1 and is used to collect the surface runoff rainwater of each block area of the container yard 7. A rainwater inlet 5 is arranged at the lowest point of the open drainage ditch without cover 2, and the rainwater inlet 5 is connected to a first ditch pipe connection well 61; The slit drainage ditch 3 is arranged on the curbs on both sides of the transverse road 8 in the container yard 7 and is used to collect the surface rainwater of the road 8. A rainwater inlet 5 is arranged at the lowest point of the slit drainage ditch 3, and the rainwater inlet 5 is connected to a second ditch pipe connection well 62; The rainwater main pipe 4 is laid perpendicular to the RMG track beam 1 and communicates with the first ditch pipe connection well 61 and the second ditch pipe connection well 62; The first ditch pipe connection well 61 and the second ditch pipe connection well 62 are respectively used to receive the rainwater collected by the open drainage ditch without cover 2 and the slit drainage ditch 3; As an implementation manner, the open drainage ditch without cover 2 adopts a concrete in-situ casting process, and its cross-section is as Figure 2As shown, the inner wall of the uncovered drainage open ditch 2 is plastered with cement mortar, the joint between the bottom of the ditch and the ditch wall is rounded, and the bottom of the ditch has a slope of 1‰ - 2‰.

[0028] As an implementation method, the rainwater main pipe 4 is installed 30 cm higher than the bottoms of the first ditch pipe connection well 61 and the second ditch pipe connection well 62 to prevent sediment in the first ditch pipe connection well 61 and the second ditch pipe connection well 62 from entering the rainwater main pipe 4.

[0029] As an implementation method, the widths and depths of the uncovered drainage open ditch 2 and the slit drainage ditch 3, the slit width of the slit drainage ditch 3, and the pipe diameter of the rainwater main pipe 4 are all calculated based on the area of the collected rainwater and the local precipitation.

[0030] As an implementation method, for the slit drainage ditch 3, its cross-section is as Figure 3 shown, the four corners of the inner wall are arc-shaped, and the slit drainage ditch 3 is integrally assembled by precast components, with strong load-bearing capacity.

[0031] As an implementation method, the longitudinal road 8 of the container yard 7 slopes towards both sides, and the rainwater on the road surface drains into the uncovered drainage open ditch 2 of the nearby container area.

[0032] Preferably, the cover plate of the first ditch pipe connection well 61 is a ductile iron manhole cover. After the surface is hot-dip galvanized, an epoxy-based polymer protective coating is applied to enhance corrosion resistance; the cover plate of the second ditch pipe connection well 62 is a ductile iron cover plate or a steel grating cover plate, which can effectively prevent the high-corrosion environment of the port terminal from eroding it and effectively reduce the later maintenance cost.

[0033] The technical effects achieved by this embodiment are as follows: An uncovered drainage open ditch is arranged in the middle of the container yard, so that the low elevation point is in the drainage ditch, avoiding poor drainage caused by uneven ground settlement in the later stage and effectively reducing the later maintenance cost; arranging an uncovered drainage open ditch in the middle of the site is convenient for later cleaning, management and maintenance; the slit drainage ditch is used at the road edge, which can avoid being damaged by passing vehicles and has little impact on the environmental visual effect. By adopting a more environmentally friendly and sustainable drainage method, the impact on the port area environment is reduced, which conforms to the improvement of current environmental awareness and the promotion of the concept of sustainable development; by optimizing the drainage layout, the number of drainage ditches is reduced, and further reducing the number of drainage structures such as rainwater inspection wells and ditch pipe wells. Using an uncovered drainage open ditch in the middle of the container yard can greatly reduce the upfront investment in the project.

[0034] Embodiment 2 Based on Embodiment 1, this embodiment provides an implementation method for a container yard drainage system. Its drainage plan view is as Figure 1 shown, and a cross-section of the layout of a container yard drainage system is as Figure 4 shown, specifically as follows: Step S1: A coverless drainage open ditch 2 parallel to the RMG track beam 1 is arranged at the horizontal center line of each block area. The coverless drainage open ditch 2 is a local low point, and the ground on both sides slopes from the RMG track beam 1 towards the coverless drainage open ditch 2. Step S2: The slit drainage ditches 3 are respectively arranged on the curbs on both sides of the horizontal road 8 in the container yard 7 for collecting the rainwater on the ground of the road 8. The center line of the road 8 is a high point, and it slopes towards the slit drainage ditches 3 along the cross slope direction of the road 8. Step S3: At a quarter of the distance from the end at both ends of each block area, a rainwater main pipe 4 is vertically arranged perpendicular to the RMG track beam 1. The rainwater main pipe 4 receives the rainwater collected by the coverless drainage open ditch 2 and the slit drainage ditches 3 through the first trench pipe connection well 61 and the second trench pipe connection well 62. The rainwater in the rainwater main pipe 4 is discharged into the port drainage pipe and then discharged into the sea after treatment.

[0035] As an implementation manner, in step S1, the slope of the ground on both sides from the RMG track beam 1 towards the coverless drainage open ditch 2 is 3‰ - 5‰.

[0036] As an implementation manner, in step S2, the slope of the road 8 towards the slit drainage ditches 3 along the cross slope direction is 3‰ - 5‰.

[0037] The technical effects achieved by this embodiment are as follows: By optimizing the drainage layout, the number of drainage ditches is reduced, and further the number of drainage structures such as rain inspection wells and trench pipe wells is reduced; The drainage main pipe is arranged in the container yard, reducing the rolling of vehicles and effectively reducing the damage of the pipeline; The two-way slope of the automated heavy container area drains towards the coverless drainage open ditch at the center line, enabling the rainwater to quickly drain into the coverless drainage open ditch in the container yard; Trench pipe connection wells are arranged at the quarter positions at both ends of the drainage ditches in the container yard and on the road, enabling the rainwater in the drainage ditches to drain to the trench pipe connection wells in the shortest path, significantly improving the drainage efficiency; The middle of the container yard uses a concrete coverless drainage open ditch, and the road drainage ditch uses precast drainage pipes, optimizing the number of connection wells, making the construction process simpler and saving construction time.

[0038] Comparative Example 1 This comparative example provides an implementation method of a drainage system for a container yard in the prior art, and its drainage plan view is as Figure 5 shown, specifically as follows: The container yard 7 includes multiple block areas. Each block area is symmetrically provided with tracks for the operation and movement of container cranes and RMG track beams 1, and a port road 8 is arranged outside the container yard 7.

[0039] The drainage system includes: a coverless drainage open ditch 2, a rainwater main pipe 4, a trench pipe connection well 6, a covered drainage ditch 9, and a rain inspection well 10; The uncovered drainage open ditch 2 is arranged in the middle of the container yard 7 and is parallel to the RMG track beam 1. It is used to collect the surface runoff rainwater of each block area on the ground of the container yard 7, and the ground of the container yard 7 slopes towards the uncovered drainage open ditch 2 on both sides. The uncovered drainage open ditch 2 slopes towards both ends, and a trench pipe connection well 6 is connected to the end. The trench pipe connection well 6 is arranged at both ends of each block area. The trench pipe connection well 6 is also connected to a rain well 10 through a rainwater main pipe 4. The rain well 10 is arranged in the middle of the road 8. Two covered drainage open ditches 9 are arranged in each passage between every two adjacent block areas. Each of the covered drainage open ditches 9 is connected to a trench pipe connection well 6 at both ends. The trench pipe connection well 6 is also connected to a rain well 10 through a rainwater main pipe 4.

[0040] Comparing this comparative example with the plane of the container yard drainage system of Embodiment 1 of the present invention (as Figure 1 shown), it is not difficult to see that: In a container yard with the same area and the same layout, the number of drainage open ditches and the number of rain wells set in Embodiment 1 of the present application are much less than those in Comparative Example 1. In the case of setting two trench pipe connection wells in the same way, the uncovered drainage open ditch in the middle of each block area in Embodiment 1 of the present application reduces the rainwater path by half compared with Comparative Example 1, and the drainage efficiency is significantly improved.

[0041] The rain wells of Embodiment 1 of the present application are all arranged in the container block area, while the rain wells of Comparative Example 1 are all arranged in the middle of the road. On the one hand, the layout of Embodiment 1 makes the interface of the port road cleaner and more beautiful, and is not easily crushed by passing vehicles, thus reducing the later maintenance cost.

[0042] The above are only exemplary embodiments of the present invention, not all embodiments. Those skilled in the art should understand that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence.
