Description

Technical Field

[0001] This utility model relates to a combined foundation layout structure of a battery compartment and a booster compartment, belonging to the field of foundation engineering technology for energy storage power stations. Background Technology

[0002] Nowadays, with the large-scale application of energy storage technology, there are higher requirements for the cost and construction progress of energy storage infrastructure. An energy storage unit generally consists of three parts: battery compartment, booster compartment and cable trench. Each energy storage unit needs to be connected to the main cable trench.

[0003] Traditionally, the battery compartment and booster compartment use box-type foundations and are connected by cable trenches, ultimately connecting to the station's cable trench. This type of construction involves large amounts of excavation and concrete, and a long construction period. Typically, due to the length of the battery compartment, six piles are used; the booster compartment uses four piles. The cable trench between the battery compartment and booster compartment is connected to both via settlement joints, and its foundation is a pile foundation, requiring at least one pile. A total of 11 piles are used for one energy storage unit. Because the battery compartment, booster compartment, and cable trench are relatively lightweight, the pile reaction force is small, resulting in low pile bearing capacity utilization efficiency and waste. The foundations of the battery compartment, booster compartment, and cable trench are independent, and the settlement difference between the foundations is difficult to control, making cracking and water seepage very likely. When the cable trench drainage is poor, the cables may even be submerged in water.

[0004] An energy storage station typically has dozens to hundreds of energy storage units. Therefore, the selection or improvement of the basic type of a single energy storage unit is crucial to the cost and construction period of the entire project. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a combined foundation layout structure for the battery compartment and the pressurization compartment to solve the problems of large excavation volume, large amount of steel reinforcement and concrete consumption in the traditional box-type foundation.

[0006] To solve the above-mentioned technical problems, this utility model is implemented using the following technical solution:

[0007] A combined foundation layout structure for a battery compartment and a pressurization chamber includes: square piles, a foundation beam, a battery compartment, and a pressurization chamber;

[0008] The square piles are configured in multiple ways and installed below ground level. The polygonal closed space enclosed by the multiple square piles includes a battery compartment and a booster compartment. The support beam is installed at the upper end of the square piles in the vertical direction. The battery compartment and the booster compartment are located at the upper end of the support beam.

[0009] A cable trench is provided between the battery compartment and the pressurization compartment. The cable trench includes a tie beam, which is connected to the support beam.

[0010] Furthermore, the position where the support beam fits into the battery compartment and the booster compartment is set as a straight line, and the support beam in the middle section of the battery compartment and the booster compartment is arranged in an inclined beam manner;

[0011] The inclined beam is a connection method in which the wider of the battery compartment and the pressurization compartment is inclined towards the shorter of the two.

[0012] Furthermore, the square piles are evenly arranged along the pier cap beam, with the square piles located at both ends of the pier cap beam arranged within the pier cap beam.

[0013] Furthermore, the cable trench also includes a lower hanging plate, and the lower hanging plate and the tie beam form a U-shaped cross-section of the cable trench.

[0014] Furthermore, the cable trench formed by the lower hanging plate and the tie beam is located on the same horizontal plane as the pier beam.

[0015] Furthermore, reinforcing bars are anchored inside the pier beam, and it is connected to a concrete wall panel.

[0016] Furthermore, the concrete wall panel has embedded parts at its upper vertical end via reinforcing bars; the battery compartment and the booster compartment are welded and fixed together via the embedded parts.

[0017] Furthermore, the tie beam, pier beam, cable trench, and lower hanging plate are all located below ground level.

[0018] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0019] This application provides a combined foundation layout structure for battery compartments and booster compartments, which reduces the number of piles in each energy storage compartment, saving approximately 27% of the total number of piles. The foundation beams are buried at a shallow depth, resulting in less concrete usage and excavation. Each energy storage unit can save approximately 50% of concrete usage and reduce excavation by approximately 40%. In the traditional model, settlement joints are set between the foundations of the battery compartments and booster compartments and the cable trenches, which is cumbersome to construct and prone to water seepage, leading to water accumulation in the cable trenches and even causing the cables to be submerged in water. The combined foundation layout of the battery compartments and booster compartments uses a high-rigidity foundation beam to connect the two, eliminating the need for settlement joints between the two compartments.

Obviously, the drawings described below are only some embodiments of this disclosure. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0026] The technical solutions of this disclosure / application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure / application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure / application or its application or use. Example 1:

[0027] This embodiment provides a combined foundation layout structure for a battery compartment and a pressurization compartment, including: square piles 1, a foundation beam 2, a battery compartment 5, and a pressurization compartment 6;

[0028] The square piles 1 are configured as a plurality of piles and installed below ground. The polygonal closed space enclosed by the plurality of square piles 1 includes a battery compartment 5 and a booster compartment 6. The support beam 2 is installed at the upper end of the square piles 1 in the vertical direction. The battery compartment 5 and the booster compartment 6 are located at the upper end of the support beam 2.

[0029] A cable trench 4 is provided between the battery compartment 5 and the pressurization compartment 6. The cable trench 4 includes a tie beam 3, which is connected to the support beam 2.

[0030] The support beam 2 is set as a straight line at the position where it fits against the battery compartment 5 and the booster compartment 6, and the support beam 2 in the middle section between the battery compartment 5 and the booster compartment 6 is arranged as an inclined beam.

[0031] The inclined beam is a connection method in which the wider of the battery compartment 5 and the pressurization compartment 6 is inclined towards the shorter one.

[0032] The square piles 1 adopt a standard size of 400mm×400mm and are evenly distributed along the layout of the foundation beam 2. They mainly bear the weight from the battery compartment 5 and the booster compartment 6. The arrangement of the piles forms a polygonal closed space, which ensures stability while covering the area of ​​the battery compartment 5 and the booster compartment 6.

[0033] The square piles 1 at both ends of the pile cap beam 2 are designed to be arranged inside the pile cap beam 2, thereby forming a cantilever structure, which further improves the uniformity of pile stress and utilization efficiency.

[0034] By optimizing the arrangement of square pile 1 and pile cap beam 2, the number of piles is reduced by about 27% compared with the traditional independent box foundation design, which significantly reduces construction costs and material usage.

[0035] The shallow depth of the pier beam 2 reduces the amount of concrete used by about 50% and the amount of excavation by about 40%, significantly shortening the construction cycle and making it suitable for the needs of large-scale energy storage power station construction.

[0036] The square piles 1 are evenly arranged along the pier beam 2, wherein the square piles 1 located at both ends of the pier beam 2 are arranged in the pier beam 2.

[0037] The foundation beam 2 is installed on the upper end of the square pile 1 and is anchored to the square pile 1 with steel bars to form an integral load-bearing system. The foundation beams 2 at the bottom of the battery compartment 5 and the booster compartment 6 are arranged in a straight line to match the longitudinal requirements of the compartments. The foundation beams 2 between the two compartments are connected by inclined beams, with the inclined beams tilting from the wider compartment to the narrower compartment, thus making the stress distribution of the entire structure more reasonable. Through the design of the inclined beams, the stress on the foundation beams 2 is evenly distributed, avoiding excessive stress in one direction that could lead to deformation or cracks. The connection between the steel bar anchorage inside the foundation beam 2 and the concrete wall panel 9 further improves the overall rigidity of the structure and avoids cracking problems caused by settlement differences.

[0038] The cable trench 4 also includes a lower hanging plate 7, and the lower hanging plate 7 and the tie beam 3 form a U-shaped cross-section of the cable trench 4.

[0039] The cable trench 4 formed by the lower hanging plate 7 and the tie beam 3 is located on the same horizontal plane as the pier beam 2.

[0040] The foundation beam 2 is internally anchored with reinforcing bars and connected to a concrete wall panel 9.

[0041] The concrete wall panel 9 has a pre-embedded part 8 installed at its upper vertical end by steel bars; the battery compartment 5 and the booster compartment 6 are welded and fixed by the pre-embedded part 8.

[0042] The tie beam 3, the pier beam 2, the cable trench 4, and the lower hanging plate 7 are all located below ground level.

[0043] Cable trench 4 is located between battery compartment 5 and booster compartment 6 to lay power supply cables and protect their safe operation. Cable trench 4 is composed of tie beam 3 and lower hanging plate 7, with a U-shaped cross-section, which ensures the laying space for cables and improves the overall rigidity of the structure. Tie beam 3 is directly connected to the foundation beam 2, so that cable trench 4 and the entire foundation system form a unified mechanical structure. The lower hanging plate 7 and tie beam 3 are arranged together below the ground to ensure the safety and concealment of cable trench 4 and reduce interference from the external environment.

[0044] The foundation beam 2 is connected to the concrete wall panel 9. The concrete wall panel 9, as an extension of the equipment foundation, not only provides the installation surface for the equipment but also enhances the foundation structure's resistance to lateral forces. The upper part of the wall panel is pre-embedded with reinforcing bars and steel plate pre-embedded parts 8. The pre-embedded parts 8 are welded and fixed to the battery compartment 5 and the booster compartment 6 to ensure the stability of the equipment installation and its seismic performance. Example 2:

[0045] Based on Example 1, the battery compartment 5 is 2600mm wide, 12000mm long, and weighs 66t; the pressurization compartment 6 is 3500mm wide, 7500mm long, and weighs 30t.

[0046] The combined foundation arrangement of battery compartment 5 and pressurized compartment 6 is as follows: Figure 1 As shown. For sites with poor soil conditions, pile foundations are used. Battery compartment 5 and booster compartment 6 use piles + pile cap beam 2. The pile cap beam 2 is in the form of an inclined beam between the two. The piles are 400x400mm square piles 1, with a pile spacing of about 6 to 7 meters, for a total of 8 piles. The load effect of a single pile is about 150kN.

[0047] According to the specifications, the width of the foundation beam 2 is 150mm wider than the pile width. The beam width can be 550mm, and the beam height can be 600mm. A concrete wall is constructed on the foundation beam 2 to serve as the equipment foundation for battery compartment 5 and booster compartment 6. Battery compartment 5 and booster compartment 6 share a common foundation, and a concrete beam is used to connect the two compartments. Figure 2 As shown in the cross-section, the concrete beam uses a 200mm thick lower hanging plate 7 to form a cable trench 4. The depth and width of the cable trench 4 are determined according to requirements. Figure 3 As shown, a wall or column is constructed on the tie beam 3. In this embodiment, a wall is used, extending to the installation height of the hull. The concrete wall panel 9 is 250mm thick, and its top elevation is determined according to the manufacturer's process. The reinforcement of the concrete wall follows the structural reinforcement requirements. A steel plate is pre-embedded at the top of the wall according to the manufacturer's process requirements for later welding with the battery compartment 5 or the booster compartment 6. The battery compartment 5 and the booster compartment 6, together on their foundations, form a single unit, which is a basic energy storage unit.
