Description

Technical Field

[0001] The present invention belongs to the field of water transport engineering, and in particular relates to a water body replacement type storage field construction method and a storage field obtained by using the construction method. Background Art

[0002] A storage yard is one of the key infrastructures used for bulk cargo storage in water transport projects. Due to the need to be close to the dock, existing construction methods often involve first constructing a dike to enclose a portion of water, then converting the enclosed water area into land through hydraulic filling or land reclamation, and then building the storage yard on top of it.

[0003] The problem with existing storage yard construction methods is that the fill material placed in the water within the enclosure takes up a significant amount of space and consumes a significant amount of engineering investment; the investment in fill material reduces the enclosed space. During the filling process, the fill material primarily transforms the water environment into a dry land environment, facilitating material storage. Summary of the Invention

[0052] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; they can refer to direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0053] The first embodiment of the present application provides a construction method of a water displacement storage field, such as Figure 1-5 As shown, the following steps are included:

[0054] (1) Construction of water-stop embankment 1:

[0055] In one embodiment, a cylindrical structure 101 can be inserted into the water to reinforce the foundation of the enclosure and serve as a water-stopping and enclosure structure to form a water-stop enclosure 1. Specifically: the cylindrical structure 101 includes a cylindrical steel plate 1011 and a sub-grid steel plate 1012, such as Figure 1 and Figure 2 .

[0056] First, the cylindrical steel plate 1011 is inserted into the soft soil foundation to enhance the soil shear strength. The cylindrical steel plate 1011 can be inserted into the soft soil by using a vibrating hammer set suspended from a crane.

[0057] Then, two auxiliary grid steel plates 1012 are inserted into the soft soil between each two adjacent cylindrical steel plates 1011 along the tongue and groove (not shown in the figure, the tongue and groove in the prior art can be used) on the outer wall of the cylindrical steel plates 1011 to close the gap between the adjacent cylindrical steel plates 1011. Sealing material is applied to the connection between the auxiliary grid steel plates 1012 and the tongue and groove to achieve watertightness.

[0058] The auxiliary grid steel plate 1012 can also be inserted into the soft foundation using a vibratory hammer system suspended from a crane vessel. The sealing material can be a mixture of sawdust, asphalt, or other materials pre-placed in the mortise to maintain a watertight seal during the insertion of the auxiliary grid steel plate 1012. Alternatively, the sealing material can be cement slurry, which is injected into the mortise using a preset pipeline pressure after the auxiliary grid steel plate 1012 is inserted into the mortise, thereby achieving a watertight seal.

[0059] Secondly, the interior of the cylindrical steel plate 1011 and the inner cavity 1013 formed between every two opposing auxiliary grid steel plates 1012 are backfilled to form the water-stop embankment 1.

[0060] The backfill can be carried out using sand and gravel, either from the water or from land. The pressure from the sand and gravel prevents the cylindrical steel plate from shrinking. The strength of the sand and gravel and the cylindrical structure 101 prevents the cylindrical steel plate from bending or breaking. The gravity of the sand and gravel, the gravity of the cylindrical structure 101, and the frictional resistance of its buried portion prevent the water-stop embankment 1 from tipping or sliding, thus maintaining overall stability. The top of the water-stop embankment 1 can also be leveled and compacted to create a construction road for the passage of construction machinery and vehicles.

[0061] (2) Enclosure and drainage construction

[0062] After the water-stop embankment 1 is sealed, the water within its enclosed area is removed, exposing the pit 2 and creating dry construction conditions. Depending on actual conditions, the pit 2 can be leveled to facilitate the construction of the storage yard 3 within the water-stop embankment 1. Leveling refers to making the pit level in whole or in part, and does not involve conventional filling; the primary purpose of filling is to increase the height, and the material used is significantly higher than for leveling.

[0063] (3) Construction of riprap prism 4

[0064] like Figure 4 As shown, the riprap prisms 4 can be constructed on the inner and outer sides of the water-stop embankment 1 respectively; so that the riprap prisms 4 roughly form a right-angled trapezoidal shape on the inner and outer sides that fits the water-stop embankment 1 respectively, and the upper surface of the riprap prisms 4 is roughly flush with the upper surface of the water-stop embankment 1.

[0065] The portion of the riprap prism 4 below the water surface can be filled from the water using a riprap boat, or partially filled using land-based equipment, with the remaining portion filled from the water using a riprap boat. The portion of the riprap prism 4 above the water surface can be filled using land-based equipment. The riprap prism 102 inside the waterstop embankment can also be filled entirely using land-based equipment.

[0066] The upper part of the water-stop embankment 1 or the upper part of the riprap prism 4 located outside can also be constructed to form an upwardly extending wave-blocking wall 5 to reduce the number of waves entering the water-stop embankment 1. The wave-blocking wall 5 can be made of reinforced concrete.

[0067] (4) Construction of Yard 3

[0068] After the dry construction conditions are formed, the yard 3 is constructed, including the construction of the low-level floor 6 and the high-level floor 7. The low-level floor 6 is lower than the average water level outside the water-stopping embankment 1; depending on the actual water depth and construction environment, it may be 3-20m lower than the average water level to form material storage conditions. Or, as Figure 7 As shown, the average depth from the pit body 2 to the top of the water-stopping embankment 1 is L1, and the depth from the surface of the low-level floor 6 to the top of the water-stopping embankment 1 is L2. Then: 100% ≥ L2 / L1 ≥ 50%. For example, L2 / L1 ≥ 60%, L2 / L1 ≥ 65%, L2 / L1 ≥ 70%, L2 / L1 ≥ 75%, L2 / L1 ≥ 80%, etc. Because the surface of the low-level floor 6 is below the water surface, more usable space is created above it. The high-level floor 7 can be built on the basis of the low-level floor 6, its height is higher, creating conditions for the installation and operation of stacking and reclaiming equipment.

[0069] More specifically: Figure 7 and Figure 8As shown, a permeable cushion layer 601, a water-blocking cushion layer 602, a waterproof layer 603 and a bottom plate layer 604 are formed in sequence from bottom to top in the pit body 2 after drainage to form the low-level floor 6. The permeable cushion layer 601 can be formed by laying permeable gravel in the pit body 2. Since water may seep into the pit body 2, it will generate a buoyancy force on the low-level floor 6, which may break the low-level floor 6. By providing the permeable cushion layer 601, the pressure of the water can be reduced or dissipated, protecting other layers above from being crushed. Therefore, the permeable cushion layer 601 has both reverse filtration and pressure-reducing drainage functions. The water-blocking cushion layer 602 can be formed by pouring cement or concrete on the permeable cushion layer 601. The water-blocking cushion layer 602 can block water to a certain extent and facilitates the subsequent construction of the waterproof layer 603, becoming a connecting layer between the permeable cushion layer 601 and the waterproof layer 603. The waterproof layer 603 can be formed by coating a waterproof material on the water-blocking cushion layer 602 or laying a physical waterproof layer (such as a multi-layered or partially stacked waterproof geotextile), which plays the main waterproofing function and prevents water from seeping upward into the surface of the low-level floor 6. The bottom plate layer 604 located on the waterproof layer 603 is conventionally cast with cement or concrete. Figure 8 As shown, the bottom plate layer 604 also has spaced-apart ground beams 6041 extending downward. The ground beams 6041 are plate structures that extend into the pit body 2, thereby increasing the bearing capacity of the low-level floor 6.

[0070] (5) Construction of warehouse body 8

[0071] A bin body 8 is provided on the low floor 6, comprising a storage bin 801 and a ballast bin 802; wherein the ballast bin 802 is evenly distributed near the storage bin 801. The storage bin 801 is mainly used to store materials (such as ore, coal, food, etc.); the ballast bin 802 is mainly used to fill ballast (such as sand or stone, etc.) when the weight of the storage bin 801 is relatively light. Considering that there may be water seepage at the bottom of the low floor 6 (or the water-blocking cushion 602), when there is material of appropriate weight in the storage bin 801, a counter-pressure will be formed on the water seepage to overcome the buoyancy of the water seepage. However, when there is less material or no material in the storage bin 801, in order to avoid the damage to the low floor 6 caused by the buoyancy generated by the water seepage, ballast can be filled in the ballast bin 802 to increase the counter-pressure of the low floor 6 against the water seepage. It can be understood that the storage bin 801 and the ballast bin 802 can be used in combination; for example, when there is a lot of material, the material can be stored in the storage bin 801 and the ballast bin 802 at the same time, so that the ballast bin 802 also has the function of the storage bin 801; when there is less material, ballast can also be filled in the storage bin 801, so that the storage bin 801 has the function of the ballast bin 802.

[0072] The storage bin 801 and the ballast bin 802 can be arranged in zones, sections, and layers to rationally utilize the space above the low floor 6. Since the low floor 6 is located below the average water level, the space provided above it is much larger than the space formed by the stockpile obtained by conventional filling methods, thereby greatly increasing the height and volume of the storage bin 801 and allowing for the storage of more materials. In one embodiment, the storage bin 801 and the ballast bin 802 are both long strips and are spaced apart. Figure 3-6 As shown, the storage bins 801 and ballast bins 802 are both rectangular; adjacent storage bins 801 and ballast bins 802 share the same long side wall 803; and the short side walls of multiple side-by-side storage bins 801 and ballast bins 802 form a common side wall 804. In order to store more materials, the width of the storage bins 801 is greater than that of the ballast bins 802.

[0073] In order to facilitate long-term storage of materials, a waterproof layer can be applied around and on the bottom of the storage bin 801 to enhance the waterproof effect.

[0074] (6) Construction of high floor

[0075] The stacking and reclaiming equipment mainly includes a stacker and a reclaimer, which are very heavy. In conventional use, in order to facilitate the movement of the stacking and reclaiming equipment, it is often necessary to pile on the foundation, then lay track beams on the ground, and lay tracks for the stacking and reclaiming equipment to move on the track beams. In the yard 3, the stacking and reclaiming equipment also requires special walking tracks. As described in step (4), a higher high-level floor 7 can be built on the basis of the low-level floor 6 to become a condition for the stacking and reclaiming equipment to move. However, if multiple high-level floor 7 passages are blindly built on the low-level floor 6, the high-level floor 7 will occupy too much space, thereby squeezing the space of the warehouse body 8.

[0076] In this embodiment, in order to solve the above problems, a high floor 7 can be built on the warehouse body 8. More specifically, Figure 3-6 As shown, a main road 701 of the elevated floor 7 is constructed along a direction roughly perpendicular to the long strip or rectangular warehouse body 8; a support plate 805 is provided in the warehouse body 8 below corresponding to the main road 701, which can be a steel plate or a reinforced concrete plate, forming conditions for supporting the stacking and reclaiming equipment to move on the main road 701. A branch road 702 of the elevated floor 7 is formed above the ballast warehouse 802, which is connected to the main road 701 and can also be used for the stacking and reclaiming equipment to move. Specifically, the long side wall 803 of the ballast warehouse 802 can be made of a relatively high-strength material such as reinforced concrete or steel structure, and its height is roughly the same as the elevated floor 7 (or main road 701); thereby, the walking tracks of the stacker and the reclaimer can be laid on the long side wall 803 of the ballast warehouse 802, as shown in FIG. Figure 5 and Figure 6 shown.

[0077] By setting the main road 701 and branch roads 702 of the elevated floor 7, the stacking and reclaiming equipment from the main road 701 can reach each branch road 702, thereby stacking or reclaiming materials along the length direction of the storage bin 801. Figure 6 As shown, the stacker can move along the branch road 702 on the first row of ballast bins 802 to stack materials in the first row of storage bins 801. The figure is a schematic diagram after the stacking is completed.

[0078] The long sidewalls 803 of the ballast tank 802 are provided with connecting beams 806 located above the long sidewalls 803 of the ballast tank 802. These connecting beams 806 are used to connect two adjacent long sidewalls 803 within the ballast tank 802. For example, multiple connecting beams 806 can be welded between the two long sidewalls. This arrangement can pull the upper portions of the long sidewalls 803 together, thereby overcoming the outward lateral pressure exerted on the long sidewalls 803 by the ballast load (e.g., a stacker / reclaimer) above, and thus increasing load stability.

[0079] It is worth noting that the order of the steps described in this embodiment is merely a description order, and in actual operation, it can be adjusted according to actual needs. Therefore, the description order does not constitute an absolute limitation to this application.

[0080] This embodiment creates more storage / warehouse space by constructing a low-level floor 6 directly within pit 2, lowering it below the average water level outside. Furthermore, by utilizing the vast majority of pit 2's surface area directly as storage / warehouse space, this embodiment avoids the need for conventional filling of pit 2, saving significant amounts of filler material, labor, and machinery, significantly improving the project's cost-effectiveness.

[0081] The second embodiment of the present application provides a water-displacement storage site, which can be constructed using the construction method described in any of the above embodiments. The water-displacement storage site comprises: a water-stopping embankment 1 and a storage yard 3; wherein the outer side of the water-stopping embankment 1 is adjacent to the water body; the storage yard 3 is formed within the internal space enclosed by the water-stopping embankment 1, and is located on a pit 2 formed after the water inside the water-stopping embankment 1 is drained.

[0082] The water-stop embankment 1 has a water-stopping function, preventing water from outside from entering the interior of the water-stop embankment 1; the water-stop embankment 1 can be constructed using the embankment 1 construction method in the prior art. As an embodiment, the water-stop embankment 1 includes a plurality of cylindrical steel plates 1011 and auxiliary grid steel plates 1012 located between adjacent cylindrical steel plates 1011. The cylindrical steel plates 1011 are cylindrical and are spaced apart along the length of the water-stop embankment 1. The auxiliary grid steel plates 1012 are arc-shaped and are in close contact with the cylindrical steel plates 1011 through the tongue and groove on the cylindrical steel plates 1011 to stop water. In one embodiment, there are two oppositely arranged auxiliary grid steel plates 1012 between adjacent cylindrical steel plates 1011, and the arc-shaped convex surface of each auxiliary grid steel plate 1012 faces outward, forming an inner cavity 1013 therebetween. The interior of the cylindrical steel plate 1011 and the inner cavity 1013 are backfilled with backfill soil to increase the stability of the water-stop embankment 1.

[0083] Optionally, riprap prisms 4 are provided on the inner and outer sides of the water-stop embankment 1, respectively, to reduce the lateral pressure exerted by the inner pile on the embankment 1 and to form a counterpressure on the foundation; and to reduce the force exerted by waves or currents on the embankment 1 and to form a counterpressure on the foundation, thereby enhancing the stability of the embankment 1. A wave barrier 5 may be provided on the top of the embankment 1 to reduce overtopping.

[0084] The yard 3 includes a lower low-level floor 6 and a higher high-level floor 7. The low-level floor 6 includes a permeable cushion layer 601, a water-blocking cushion layer 602, a waterproof layer 03 and a bottom plate layer 604 distributed from bottom to top. The permeable cushion layer 601 has a water-permeable function and can be paved in the pit body 2 with permeable materials (such as crushed stone, gravel); its thickness is 200-3000mm. The water-blocking cushion layer 602 is a cement layer or a concrete layer, which has a certain degree of water-blocking effect; its thickness is 100-300mm. The waterproof layer 603 is formed by coating a waterproof material on the water-blocking cushion layer 602 or laying a physical waterproof layer, and its thickness is 0.1-10mm. The bottom plate layer 604 is a cement layer or a concrete layer, which is a working surface layer; its thickness is 300-2500mm. The bottom plate layer 604 further has spaced-apart ground beams 6041 . The ground beams 6041 are a plurality of parallel plate structures and are formed by extending downward from the bottom plate layer 604 .

[0085] The surface of the low floor 6 is at least 1m lower than the average water level outside the water-stopping embankment 1, for example, 1-20m (such as 2m, 3m, 5m, 8m, 10m, 12m, 15m, 18m, etc.), which makes use of the space occupied by the original water body and greatly increases the material storage space.

[0086] The low floor 6 is provided with a storage body 8, comprising a storage bin 801 and a ballast tank 802. The ballast tank 802 is located adjacent to the storage bin 801. The storage bin 801 is used to store materials; the ballast tank 802 is used to fill the storage bin 801 with ballast to supplement the weight of the storage bin 801 when the weight is insufficient, thereby increasing the downward pressure of the low floor 6.

[0087] like Figure 4 As shown, in one embodiment, the storage bins 801 and the ballast tanks 802 are both rectangular, the width of the storage bins 801 is greater than the width of the ballast tanks 802, and the two are arranged at intervals; so that adjacent storage bins 801 and ballast tanks 802 share the same long side wall 803, and the short side walls of multiple storage bins 801 and the short side walls of the ballast tanks 802 arranged side by side form a common side wall 804.

[0088] The high floor 7 can be built on the low floor 6 for the movement of the stacking and reclaiming equipment. In one embodiment, the high floor 7 includes a main road 701 and a plurality of branch roads 702 connected to the main road 701. Figure 3-6 As shown, the main road 701 is arranged perpendicular to the length direction of the storage bin 801 and the ballast tank 802, and is located above the storage bin 801 and the ballast tank 802; the branch road 702 is formed above the ballast tank 802.

[0089] Furthermore, a support plate 805 is vertically provided in the silo 8 (storage silo 801 and ballast tank 802) below the main road 701. The support plate 805 is a reinforced concrete plate or a steel plate, which is used to support the main road 701. The long side wall 803 of the ballast tank is made of reinforced concrete or steel structure, and its height is flush with the height of the main road 701, so that the upper part of the ballast tank 802 serves as a branch road 702 for laying the track of the stacking and reclaiming equipment, such as Figure 7 As shown. Furthermore, the ballast tank 802 may be provided with a plurality of connecting beams 806, located between the upper portions of the two opposing long side walls 803 of the ballast tank, to connect the two long side walls and enhance pressure resistance. In this embodiment, the long side walls of the ballast tank can also serve as the foundation for the running track of the stacking and reclaiming equipment, eliminating the need for additional space for the track foundation, thereby increasing the storage space of the tank body 8.

[0090] The described embodiments are merely descriptions of the preferred embodiments of the present application and do not limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements made to the technical solutions of the present application by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present application.
