Description

Technical Field

[0001] This invention relates to the field of highly corrosive sea salt production technology, and more specifically, to a salt field device that integrates various prefabricated supporting facilities. Background Technology

[0002] The production model for sea salt in southern China has traditionally been characterized by "short, frequent, and fast" operations, relying entirely on manual labor, resulting in high labor loads and low production efficiency. Aging and damaged infrastructure in some salt fields has impacted normal crude salt production, leading to a decline in both quantity and quality. Some salt fields, due to years of flooding and idleness, have lost their production capacity. Infrastructure upgrades in salt fields play a crucial role in ensuring a stable supply of sea salt. Brine-holding ponds and access roads, as vital infrastructure, have traditionally been constructed using brick or earthen mounds, with surfaces paved with flagstones or gravel. These methods suffer from low load-bearing capacity, susceptibility to damage and pollution, and limited functionality. Modernizing brine-holding ponds and access roads involves adopting the concepts of culverts and utility tunnels to construct safe, durable, economical, and suitable engineering projects. The focus should be on addressing the following key challenges: meeting the requirements of salt production processes and usage; comprehensively considering the internal space partitioning, load-bearing capacity, pipeline installation, and foundation reservation of brine-holding ponds in an integrated design; and ensuring that building materials and construction methods can withstand the high-salt corrosion of the salt-rich environment. If traditional construction materials are used, they either struggle to meet the requirements of the highly corrosive environment of salt fields (short material lifespan) or are prohibitively expensive (difficult maintenance and high anti-corrosion design costs). Therefore, low-cost materials suitable for high-salt environments must be selected. During the renovation process, the salt fields must be kept clean to protect the algae and microorganisms, ensuring the quality of salt products. Large-scale excavation should be avoided to prevent pollution. Traditional cast-in-place methods involve large-scale excavation and heavy machinery construction, resulting in a large working area and significant disturbance and pollution to the existing salt fields. Choosing a scientific construction process is crucial. Construction projects are greatly affected by coastal climate and weather; frequent rainfall and strong winds impact construction progress and quality. Traditional cast-in-place methods involve a large amount of on-site work and a long construction period, necessitating the selection of construction technologies suitable for the local environment. Existing widely used technologies create box culverts with relatively fixed spaces and certain requirements for geology and foundations, making them unsuitable for high-salt corrosive environments. Conventional box culverts, underground utility tunnels, or integrated utility trenches have high construction requirements, high costs, limited functionality, and low overall economic benefits. Summary of the Invention

[0003] In view of this, the present invention proposes a salt field device integrating various prefabricated supporting facilities, comprising:

[0004] A brine retention tank is located on the salt pool, with its lower part inserted into the foundation, its middle part passing through the salt pool, and its upper part exposed above the salt pool. The brine retention tank is composed of a prefabricated structure.

[0005] The lump is located above the brine-preserving tank, with both ends connected to the tank wall. The lump is composed of a prefabricated structure.

[0006] Furthermore, the brine retention tank includes a bottom plate, side walls, and a support bracket. The bottom plate is located in the foundation, and the side walls are vertically arranged around the sides of the bottom plate to separate the interior of the brine retention tank from the foundation and the salt pond. The support bracket is located on the top of the side walls, and its top surface is reserved for connecting parts of an intelligent salt collection device.

[0007] Preferably, the base plate is completely buried in the foundation soil below the salt pond with a burial depth of 1000 mm or more.

[0008] Specifically, the sidewall is used to resist water and soil pressure. The thickness of the sidewall is no greater than the thickness of the base plate. Part of the sidewall protrudes above the salt pond, while part is buried in the foundation soil below the salt pond. The corbel is located at the top of the sidewall, with a pre-installed connector for intelligent salt collection equipment on its top surface. The corbel is a variable cross-section wedge shape, with its root height calculated and determined according to the requirements of the salt collection equipment. The end height is no less than 100mm, and its length is no less than 150mm from the sidewall.

[0009] Furthermore, a plain concrete pad is laid at the bottom of the brine-preserving tank, with the laying width being a preset width extended outward from the width of the brine-preserving tank on each side.

[0010] Preferably, the width of the plain concrete cushion layer is 100mm wider on each side than the width of the brine retention tank.

[0011] Specifically, the plain concrete cushion layer ensures that the load above it is evenly transferred to the foundation and serves as the bottom formwork when the bottom slab of the brine retention tank is poured.

[0012] Furthermore, an anchor is provided at the bottom of the brine retention tank, with one end of the anchor fixedly connected to the bottom of the brine retention tank and the other end anchored in the foundation.

[0013] Specifically, the function of the anchors is to resist buoyancy and overturning, and maintain the overall stability of the structure. The anchors are anchored to the solid foundation below, and the number, position and spacing are calculated and determined as needed. If the structure's own weight can resist buoyancy and overturning, they may not be required.

[0014] Preferably, the anchor is made of corrosion-resistant materials such as stainless steel.

[0015] Furthermore, a haunch structure is provided between the base plate and the side wall to strengthen the strength of the root of the side wall, and the haunch angle of the haunch structure is 45°.

[0016] Furthermore, the tuolu includes multiple assembly units (a), which are sequentially assembled and connected to form the tuolu. Each assembly unit (a) includes transverse ribs, longitudinal ribs, and interrib plates. Each transverse rib and longitudinal rib includes two units, which are sequentially spaced around to form a rectangular structure. The interrib plates are supported on the transverse ribs and longitudinal ribs on all four sides. Multiple assembly units (a) are connected together through the transverse ribs to form the entire tuolu. The longitudinal ribs located at both ends of the tuolu can support and connect to the wall of the brine retention tank.

[0017] Furthermore, the two ends of the rib plate are longitudinal ribs with rectangular cross sections. The longitudinal ribs are arranged with pin key reserved holes at preset distances, which are connected to the top of the side wall of the brine pool by bolts. The size of the reserved hole is larger than the diameter of the bolt. After the bolts are installed and tightened, the gap of the hole is filled with inorganic high-performance composite grout. The surface of the grout is sealed with mortar to make it flat and dense.

[0018] Specifically, the overall structure of Tuolu is made of inorganic high-performance composite materials and reinforced with corrosion-resistant steel bars.

[0019] Specifically, the ridge can serve as both a cover for the brine-preserving tank and a road surface for pedestrian and vehicular traffic. The transverse ribs support the inter-rib plates and divide the inter-rib plate units, while the longitudinal ribs support the inter-rib plates and connect to the sidewalls of the brine-preserving tank. The inter-rib plates directly bear the loads of pedestrian and vehicular traffic. The inter-rib plates are located between the transverse and longitudinal ribs and are supported on all four sides. The transverse and longitudinal ribs are at the same height.

[0020] Furthermore, a seam is formed between the assembly units (a), and the seam is sealed with a sealant.

[0021] Furthermore, the brine retention tank is composed of multiple assembly units (II), with adjacent assembly units (II) forming assembly unit joints, which are connected and fitted together by a set assembly part. The assembly part includes corrosion-resistant connecting boxes located on both sides of the assembly unit joint, and its bottom is connected to the brine retention tank structure by a set pre-embedded steel bar. The corrosion-resistant connecting boxes located on both sides of the assembly unit joint are connected by tie bolts to realize the assembly of two adjacent assembly units (II). Preferably, the surface of the assembly unit joint is sealed with caulking sealant. Preferably, the middle part of the assembly unit joint is sealed with a rubber composite sealing ring.

[0022] Furthermore, the standard assembly unit of the brine retention tank is several times the length of the standard assembly unit of the tuolu (lump road), and multiple prefabricated brine retention tanks and tuolu are assembled sequentially and arranged in a row.

[0023] Specifically, the brine retention tank is constructed using inorganic high-performance composite materials, reinforced with internal corrosion-resistant ribs to meet structural requirements. These inorganic high-performance composite materials possess advantages such as high strength, high toughness, and high corrosion resistance. Furthermore, the material does not leach out, has a smooth surface, and does not cause secondary pollution to the brine.

[0024] Furthermore, a support and hanger device is provided on one side of the brine preservation tank. Its two ends are connected to the side wall of the brine preservation tank and the other end is connected to the road through corresponding pre-embedded parts.

[0025] Preferably, the support and hanger device adopts an L-shaped prefabricated component, with one end of the horizontal part connected to the side wall of the brine preservation tank through a pre-embedded part, and one end of the vertical part connected to the slab road through a pre-embedded part.

[0026] Specifically, the support and hanger device and the embedded parts, as supporting equipment for the operation and maintenance of brine retention ponds, can greatly improve the feasibility, economy, and safety of modern saltworks infrastructure renovation.

[0027] Furthermore, the surface of the roadbed is equipped with photovoltaic glass, and a slope-finding layer is provided between the photovoltaic glass and the roadbed. Specifically, by using the photovoltaic glass and slope-finding layer as maintenance support, the feasibility, economy, and safety of modern saltworks infrastructure renovation can be greatly improved.

[0028] Specifically, the photovoltaic glass installed can provide electricity and heat for seawater concentration. Road surface photovoltaic glass is a new type of self-generating material. While measures are taken on the glass surface to ensure non-slip passage for pedestrians and vehicles, it also has high light transmittance, allowing sunlight to pass through and convert light energy into electrical energy. Information ports are reserved on the road surface for future connection to data collection equipment.

[0029] This invention provides a salt field device integrating various prefabricated supporting facilities, which has the following advantages: It includes brine retention pools, roadways, operation and maintenance facilities, and assembly units. It also features an integrated design that incorporates multiple functions such as pipeline layout, personnel and vehicle access, and equipment installation bases, reducing the area occupied by the salt field and lowering the overall cost. Furthermore, it uses inorganic high-performance composite materials as the structural load-bearing material. Inorganic high-performance composite materials have high strength and high toughness mechanical properties, high corrosion resistance chemical properties, do not precipitate, have a smooth surface, do not cause secondary pollution to the brine, and are highly designable and environmentally friendly. High strength allows for lightweight prefabricated components, meeting load-bearing requirements with smaller component sizes. High corrosion resistance extends the structural lifespan and reduces operating costs. Furthermore, given the tidal flat geological characteristics of salt fields, a prefabricated assembly design is adopted, with multiple standard units assembled into a whole. This modular assembly structure is suitable for construction in near-shore tidal flat environments, making it more convenient and feasible. It avoids large-scale excavation, maintains site cleanliness, does not affect the production of surrounding salt fields, and reduces construction workload and shortens the construction cycle. Moreover, it facilitates subsequent expansion and renovation. In summary, this invention, integrating prefabricated brine retention ponds, access roads, and operation and maintenance support into a salt field device, significantly improves the feasibility, economy, and safety of modern salt field infrastructure renovation compared to existing box culvert structures.

The prefabricated brine retention tank 1 is composed of several prefabricated units continuously spliced ​​together. The assembly part 3 is provided on the main body of the brine retention tank 1 and is used to connect and cooperate with the assembly parts of other prefabricated units. Several corrosion-resistant connection boxes 31 are pre-embedded in the bottom plate 11 and side wall 12 of the brine retention tank 1 near the joint 32 of the prefabricated units. The tank body structure material of the brine retention tank 1 is made of inorganic high-performance composite material, with internal corrosion-resistant ribs to meet the stress requirements.

[0061] Figure 4 yes Figure 2 The schematic diagram of the AA cross-section structure shows that the bottom plate 11 and side wall 12 of the brine holding tank have several corrosion-resistant connection boxes 33 pre-embedded near the joint 31 of the prefabricated unit. The bottom of the corrosion-resistant connection box 33 is connected to the structure of the brine holding tank 1 by pre-embedded steel bars 33.

[0062] Figure 5 yes Figure 3 The schematic diagram of the BB cross-section structure shows that the structure of Tuolu 2 is made of inorganic high-performance composite material and is reinforced with corrosion-resistant steel bars. The two ends of the rib plate 23 are longitudinal ribs 22 with rectangular cross sections. The longitudinal ribs 22 are arranged with pin key reserved holes at intervals and are connected to the top of the side wall 12 of the brine preservation tank by bolts 25. The reserved hole size is larger than the bolt diameter. After the bolts 25 are installed and tightened, the gaps in the holes are filled with inorganic high-performance composite grout 26. The surface of Tuolu is sealed with mortar 27 to make it flat and dense.

[0063] Figure 6 yes Figure 3 The schematic diagram of the CC cross-section structure shows that the two ends of the inter-rib plate 23 are transverse ribs 21. The transverse ribs 21 have an approximately rectangular cross section and are slightly inclined near the inner vertical edge of the inter-rib plate 23 to facilitate prefabrication and demolding. The tongue and groove joint 24 at the end of the transverse rib 21 adopts a tongue and groove structure. After the tongue and groove joint 2 unit is assembled, the joint sealant 6 is used to seal it.

[0064] Furthermore, because the prefabricated brine-preserving tank 1 and the access road 2 also include an assembly section 3, multiple prefabricated brine-preserving tanks 1 and access roads 2 can be assembled into an integral structural unit through the assembly section 3. This modular assembly structure is suitable for construction in the geological environment of salt lakes and tidal flats, making it more convenient and feasible, and effectively controlling transportation and construction conditions and costs. Moreover, it facilitates subsequent expansion and modification. In addition, the access road 2 can serve as both a cover for the brine-preserving tank, ensuring the brine inside is sealed and unaffected by the open environment, and a transportation function during salt production. That is, the entire device can function as a road structure, providing a safe passage for workers and vehicles, and also as a transportation and storage space, meeting the necessary transportation and storage functions for production and daily life.

[0065] In summary, the saltworks device provided by this invention, integrating various prefabricated supporting facilities, has the following beneficial technical effects: The integrated design, including brine retention ponds, pipeline layout, personnel and vehicle access, and equipment installation bases, reduces the area occupied by the salt field and lowers the overall cost. Furthermore, the use of inorganic high-performance composite materials as the structural load-bearing material possesses high strength and high toughness in mechanical properties, high corrosion resistance in chemical properties, and is highly designable and environmentally friendly. High strength allows for lightweight prefabricated components, meeting load-bearing requirements with smaller component sizes, while high corrosion resistance extends the structural service life and reduces operating costs. Additionally, given the tidal flat geological characteristics of saltworks, the prefabricated assembly design, with multiple standard units assembled into a whole, is suitable for construction in near-shore tidal flat environments, making it more convenient and feasible. It avoids large-scale excavation, maintains site cleanliness, does not affect the production of surrounding salt fields, and reduces construction workload and shortens the construction cycle. Moreover, it facilitates subsequent expansion and renovation. In summary, the saltworks device of the present invention, which integrates prefabricated brine retention tanks, roadways, and operation and maintenance facilities, can greatly improve the feasibility, economy, and safety of modern saltworks infrastructure renovation compared to existing box culvert structures.
