Description

Technical Field

[0001] The invention belongs to the field of drainage, and in particular relates to a sponge yard layout structure of an automated container and an implementation method thereof. Background Art

[0002] In order to improve the safety of the automated container yard, each container area of ​​the yard is enclosed by a fence. During normal operation, staff do not need to enter the container area of ​​the yard. According to the load distribution characteristics of the container yard: the force in the corner area is concentrated and large, and the load in the filling area is small and basically unloaded. In order to save construction costs, the foundation of the corner area is usually strengthened and the load in the filling area is simplified. Currently, there are two common structural schemes: 1) Scheme 1: The corner area adopts pile foundation + reinforced concrete box corner beam foundation, and the filling area adopts asphalt concrete or interlocking block paving. 2) Scheme 2: The corner area adopts reinforced concrete strip foundation, and the filling area also adopts asphalt concrete or interlocking block paving.

[0003] Regardless of the box corner foundation scheme adopted, the filling area is currently usually paved with asphalt concrete or interlocking blocks, and the elevation of the filling area is the same as that of the site road. Chinese patent CN216839756U (publication date: June 28, 2022) discloses a drainage mechanism for a container yard, which realizes timely drainage and improves the degree of drainage automation by setting up U-shaped drainage ditches, pump boxes, diversion platforms, etc. There is still a certain gap between the yard design concept and the requirements of "natural accumulation, natural infiltration, and natural purification" of the sponge city. In addition, the current yard drainage ditch mostly adopts the solution of on-site cast open ditch to achieve the slope requirements of the drainage ditch. The on-site operation of this solution is high-intensity and time-consuming.

[0004] Chinese patent CN201920731498 (publication date: April 3, 2020) discloses a rainwater drainage structure for a sunken container yard in a sponge port area. It mainly focuses on the drainage of container yards, and uses surface gravity flow drainage through port roads, tracks, and sunken pavements; the height difference between the sunken yard and the port road forms a reservoir for rainwater regulation to reduce the pressure on rainwater pipes and reduce the cost of drainage facilities. It only realizes the natural accumulation in the "natural accumulation, natural infiltration, and natural purification" mode of sponge cities. Further research is needed on how to better realize the "natural accumulation, natural infiltration, and natural purification" of sponge cities, and the water storage capacity, drainage capacity, and structural cost of the yard still need to be optimized. Summary of the invention

[0005] In order to solve the above problems, the present invention combines the overall horizontal sinking of the filling area of ​​the container yard, the permeable paving of the pavement, and the assembled stepped open ditch of the yard drainage ditch, and provides an automated container sponge yard layout structure and its implementation method, including a box corner foundation, a filling area, an open drainage ditch, and two sets of tracks;

[0006] The corner foundation is arranged in parallel with the filling area on the container yard and is vertically arranged with the open drainage ditch;

[0007] The open drainage ditch is arranged in the middle of the container yard;

[0008] Two sets of the tracks are arranged parallel to the open drainage ditch at the edges of both sides of the yard;

[0009] A fence is arranged around the container yard, and the outer road is connected to the edge of the yard with a descending slope;

[0010] Furthermore, an elevation difference is formed between the top of the drainage ditch and the top elevations of the tracks on both sides, and the hydraulic slope calculated based on the elevation difference and the width of the box area is 1%-3%;

[0011] Furthermore, the top elevation of the open drainage ditch is 0.05m to 0.1m higher than the filling area elevation H1, and the end is connected to the ditch pipe connection well.

[0012] Furthermore, the filling area as a whole adopts horizontal sinking and permeable paving, and the top elevation is consistent and generally lower than the top elevation of the open drainage ditch.

[0013] Furthermore, the top elevation of the box corner foundation is consistent with the top elevation of the track.

[0014] Furthermore, the open drainage ditch adopts a stepped assembled open drainage ditch, and a step is arranged at a certain interval in the open drainage ditch, and the depth of each step gradually increases along the direction of the ditch pipe connection well.

[0015] Furthermore, the open drainage ditch and the filling area are prefabricated in a factory and assembled on site.

[0016] The implementation method of the sponge yard layout structure of the automated container comprises the following steps:

[0017] S1. Produce multiple prefabricated open ditch modules and fill area modules in the factory and transport them to the construction site for rapid assembly;

[0018] S2. A connecting trench pipe connecting well is set up at one end of the yard;

[0019] S3. Use the total station to lay out the center control line and elevation control points of the drainage ditch, then excavate the trench, and lay the corner foundation, fill area foundation and track at the same time;

[0020] S4. The filling area is horizontally sunken as a whole, and the pavement is permeable;

[0021] S5. Starting from the trench pipe connection well, open ditch modules and filling area modules are laid in sequence, and a multi-stage filtration system is set on the stepped drainage open ditch;

[0022] S6. When the storage yard encounters heavy rain, the rainwater will first accumulate and infiltrate naturally in the sunken filling area. If the heavy rain exceeds a certain amount, it will enter the stepped drainage ditch to achieve natural accumulation, natural infiltration and natural purification of the rainwater.

[0023] Compared with the prior art, the technical solution of the present application has the following advantages and effects:

[0024] 1. The present application provides an automated container sponge yard layout structure, in which the filling area is paved with permeable paving, which can increase the resilience of the port drainage system, reduce the peak of rainwater from the source, and reduce the amount of rainwater discharged, meeting the "natural accumulation, natural infiltration, and natural purification" model of the sponge city, and improving the annual runoff control rate and annual runoff pollution control rate of the port area, thereby achieving carbon emission reduction in the port area;

[0025] 2. The present application provides an automated container sponge yard layout structure, in which the yard filling area adopts an overall sunken type, which can realize the natural accumulation of rainwater, reduce the amount of rainwater discharged from the source, improve the annual runoff control rate, reduce the yard filling material, and save construction costs.

[0026] 3. The present application provides an implementation method for the sponge yard layout structure of an automated container. The yard adopts assembled stepped open ditches and filling areas. Compared with on-site casting, it meets the drainage slope requirements of the open ditch, increases the drainage capacity of the open ditch, saves construction costs and time, reduces on-site work intensity, and uses factory prefabrication to reduce environmental pollution.

[0038] Example 1

[0039] This embodiment combines the elevation of the filling area of ​​the container area, the pavement of the filling area, and the open ditch structure of the filling area, and provides a sponge yard layout structure for automated containers, including a corner foundation 1, a filling area 2, an open drainage ditch 3, and two sets of tracks 4;

[0040] The corner foundation 1 is arranged in parallel and at intervals with the filling area 2 on the container yard, and is vertically arranged with the open drainage ditch 3;

[0041] The open drainage ditch 3 is arranged in the middle of the container yard;

[0042] Two groups of tracks 4 are arranged parallel to the open drainage ditch 3 at the edges of both sides of the yard;

[0043] A fence 5 is arranged outside the container yard, and an outer road 6 is connected to the edge of the yard at a descending slope of 0.5%.

[0044] Meet the no-flooding requirement;

[0045] Furthermore, a certain elevation difference is formed between the top elevation H-(I, B) of the drainage ditch 3 and the top elevation H of the tracks 4 on both sides, and the hydraulic slope calculated based on the elevation difference and the width of the box area is 1%;

[0046] Furthermore, the filling area 2 is horizontally sunken as a whole, and the overall sinking depth H1 is 0.2m compared to the top elevation H of the track 4, which can achieve the effect of natural accumulation of rainwater, reduce the amount of rainwater discharged from the source, and improve the annual runoff control rate.

[0047] See also Figure 1 , is a cross-sectional view of the filling area of ​​the sponge yard arrangement structure of the automated container in this embodiment;

[0048] The filling area 2 is horizontally sunken and permeable paved as a whole, and the overall top elevation is lower than the top elevation of the open drainage ditch 3;

[0049] The filling area 2 is paved with permeable paving, with the top layer being permeable asphalt concrete or permeable bricks, the lower layer being paved with permeable concrete, and the bottom layer being paved with a base layer of blown fill sand, soil or other materials. This reduces the runoff coefficient of the container yard, reduces peak rainfall, improves the drainage resilience of the port area, and reduces rainwater discharge from the source. Rainwater infiltrates and is purified naturally to increase the annual runoff control rate and annual runoff pollution control rate, thereby achieving carbon emission reduction.

[0050] See also Figure 2 , is a cross-sectional view of a corner foundation of the sponge yard arrangement structure of the automated container of this embodiment;

[0051] The top layer of the box corner foundation 1 is made of reinforced concrete, the lower layer is paved with plain concrete and crushed stone, and the bottom layer is paved with a base layer of blown fill sand, soil or other materials;

[0052] The elevation H of the box corner foundation 1 is consistent with the elevation H of the top of the track 4 .

[0053] See also Figure 3 , which is a longitudinal section view of an open drainage ditch of the sponge yard arrangement structure of the automated container in this embodiment;

[0054] Furthermore, the top elevation of the open drainage ditch 3 is 0.05 m higher than the elevation H1 of the filling area 2 , and the end is connected to the ditch pipe connection well 7 .

[0055] By setting the elevation of the open drainage ditch higher than the elevation of the filling area and lower than the elevation of the outer road, rainwater can be naturally accumulated in the yard, and rainwater overflow will not occur during heavy rains. In addition, setting up a ditch pipe connection well at only one end saves project costs.

[0056] Furthermore, the drainage open ditch 3 adopts a stepped assembled open ditch. According to the hydraulic gradient requirement, the drainage open ditch 3 is provided with a step every 50m or so, and the depth of each step increases by 0.05m along the direction of the ditch pipe connection well. The stepped drainage open ditch of this embodiment meets the hydraulic gradient requirement of the open ditch and increases the drainage capacity of the open ditch; the assembled drainage open ditch saves construction cost and construction time compared with the on-site cast drainage open ditch, and reduces the intensity of on-site work.

[0057] Technical effect of this embodiment: This embodiment realizes the sponge concept of "natural accumulation, natural infiltration, and natural purification" of the container yard. At the same time, in order to solve the shortcomings of on-site pouring that is time-consuming and labor-intensive, a feasible drainage arrangement is provided.

[0058] Example 2

[0059] This embodiment combines the elevation of the filling area of ​​the container area, the pavement of the filling area, and the open ditch structure of the filling area, and provides a sponge yard layout structure for automated containers, including a corner foundation 1, a filling area 2, an open drainage ditch 3, and two sets of tracks 4;

[0060] The corner foundation 1 is arranged in parallel and at intervals with the filling area 2 on the container yard, and is vertically arranged with the open drainage ditch 3;

[0061] The open drainage ditch 3 is arranged in the middle of the container yard;

[0062] Two groups of tracks 4 are arranged parallel to the open drainage ditch 3 at the edges of both sides of the yard;

[0063] The container yard is surrounded by a fence 5, and the outer road 6 is connected to the edge of the yard with a 2% descending slope to meet the requirement of no flooding;

[0064] Furthermore, a certain elevation difference is formed between the top elevation H-(I, B) of the drainage ditch 3 and the top elevation H of the tracks 4 on both sides, and the hydraulic gradient calculated based on the elevation difference and the width of the box area is 3%;

[0065] Furthermore, the filling area 2 is horizontally sunken as a whole, and the sinking depth H1 is 0.4m compared to the elevation H of the top of the track 4, which can achieve the effect of natural accumulation of rainwater, reduce the amount of rainwater discharged from the source, and improve the annual runoff control rate.

[0066] The filling area 2 is horizontally sunken and permeable paved as a whole, and the overall top elevation is lower than the top elevation of the open drainage ditch 3;

[0067] The elevation H of the box corner foundation 1 is consistent with the elevation H of the top of the track 4 .

[0068] See also Figure 3 , which is a longitudinal section view of an open drainage ditch of the sponge yard arrangement structure of the automated container in this embodiment;

[0069] Furthermore, the top elevation of the open drainage ditch 3 is 0.1 m higher than the elevation H1 of the filling area 2 , and the end is connected to the ditch pipe connection well 7 .

[0070] Furthermore, the drainage open ditch 3 adopts a stepped assembled open ditch. According to the hydraulic gradient requirement, the drainage open ditch 3 is provided with a step every 60m or so, and the depth of each step increases by 0.06m along the direction of the ditch pipe connection well. The stepped drainage open ditch of this embodiment meets the hydraulic gradient requirement of the open ditch and increases the drainage capacity of the open ditch; the assembled drainage open ditch saves construction cost and construction time compared with the on-site cast drainage open ditch, and reduces the intensity of on-site work.

[0071] Technical effect of this embodiment: This embodiment combines the overall horizontal sinking of the filling area of ​​the container yard, permeable paving, and assembled stepped open ditches for yard drainage, and provides an automated container sponge yard layout structure and its implementation method, realizing the container yard sponge concept while saving project costs.

[0074] S1. Produce multiple prefabricated open ditch modules and fill area modules in the factory and transport them to the construction site for rapid assembly;

[0075] The open channel module is made of high-strength material and is produced in a standardized manner to ensure accurate dimensions and reliable quality. The module includes a plug post and a plug hole, and each section is connected by a mortise and tenon structure to ensure overall stability and sealing.

[0076] S2, a connecting trench pipe connecting well 7 is set at one end of the yard;

[0077] S3. Use the total station to lay out the center control line and elevation control points of the drainage ditch, then excavate the trench, and lay the box corner foundation 1, the filling area 2 foundation and the track 4 at the same time;

[0079] S5, starting from the trench pipe connection well 7, laying open ditch modules and filling area modules in sequence, and setting a multi-stage filtration system on the stepped drainage open ditch 3;

[0080] The stepped drainage ditch is equipped with a multi-stage filtration system, each of which has different filtration materials and vegetation to purify rainwater layer by layer. These filtration materials include pebbles, ceramsite, gravel, etc., which remove suspended matter and dissolved pollutants in rainwater through physical filtration and microbial action.

[0081] S6. When the storage yard encounters heavy rain, the rainwater will first accumulate and infiltrate naturally in the sunken filling area 2. If the heavy rain exceeds a certain amount, it will enter the stepped drainage ditch 3 to achieve natural accumulation, natural infiltration and natural purification of the rainwater.

[0082] The technical effect of this embodiment is as follows: the structure yard filling area adopts an overall sunken type, which can realize the natural accumulation of rainwater. The stepped drainage ditch increases the retention time and infiltration area of ​​rainwater on the surface, reduces the amount of rainwater discharged from the source, and improves the annual runoff control rate. The overall structure reduces the yard filling material and saves construction costs.
