Technical Field

[0001] This utility model belongs to the field of prefabricated building technology, and specifically provides a prefabricated accident oil tank. Background Technology

[0002] Substation accident oil pools are used to collect leaked oil in the event of accidents involving power transformers and other equipment, thereby protecting the equipment and the environment. Currently, most substation accident oil pools are cast-in-place concrete structures, which have problems such as long construction periods, large on-site operating areas, high labor input, and construction noise and dust pollution.

[0003] Therefore, providing a prefabricated emergency oil tank to improve construction efficiency, shorten the construction period, and reduce manpower input has become an urgent problem to be solved. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a prefabricated emergency oil tank to solve the problems existing in traditional substation emergency oil tanks with cast-in-place concrete structures.

[0005] The technical solution provided by this utility model is: a prefabricated emergency oil tank, comprising: a prefabricated base plate, prefabricated wall panels, a prefabricated top plate, and a prefabricated inspection well. The prefabricated base plate has a groove on its upper surface, and a waterproof rubber strip is installed at the bottom of the groove.

[0014] Figure 2 This is a schematic diagram of the base plate structure;

[0015] Figure 3 This is an enlarged view of the connection between the base plate and the wall panel. Detailed Implementation

[0016] The present invention will be further explained below with reference to specific implementation schemes, but it is not limited to the present invention.

[0017] like Figures 1 to 3 As shown, this utility model provides a prefabricated emergency oil tank, including: a prefabricated base slab 1, a prefabricated wall panel 2, a prefabricated top slab 3, and a prefabricated inspection well 4. A groove 11 is provided on the upper surface of the prefabricated base slab 1, and a waterproof rubber strip 12 is provided at the bottom of the groove 11. A prefabricated steel plate 13 is also provided on the upper surface of the prefabricated base slab 1, and the prefabricated steel plate 13 is located on both sides of the groove 11. The bottom of the prefabricated wall panel 2 is provided with a locking key 21 that mates with the groove 11 and a locking mechanism 4. The bottom of the wall panel is pre-embedded with steel plate 22 corresponding to the pre-embedded steel plate 13 in the base plate. The side end of the precast wall panel 2 is provided with a pre-embedded steel plate at the end of the wall panel (not shown in the figure). The key 21 is inserted into the groove 11 and presses the waterproof tape 12. The pre-embedded steel plate 13 in the base plate is welded to the pre-embedded steel plate 22 at the bottom of the wall panel. The pre-embedded steel plates at the end of the adjacent precast wall panels 2 are welded. The precast top plate 3 is connected to the top of the precast wall panel 2. The precast inspection well 4 is connected to the top of the precast top plate 3.

[0018] The components of this prefabricated emergency oil tank are manufactured in the factory and then transported to the site for assembly, achieving miniaturization and standardization of the components. The components are assembled using welded connections, which have reliable strength and stability. In addition, the prefabricated base plate and prefabricated wall panels are welded together, and the connection is equipped with matching grooves and keyways, which extends the seepage path. The waterproof rubber strip squeezed into the bottom of the groove can improve the waterproof performance of the structure.

[0019] The production and construction process of this prefabricated emergency oil tank is as follows:

[0020] Production stage: After the components are manufactured in the factory, they are transported to the site for assembly. Since the components are flat, the factory production can adopt the form of fixed mold table + side mold. The embedded parts such as the connecting steel plates in the components can be positioned by tooling, which makes the production simpler, more efficient and cost-effective.

[0021] Construction phase: After the foundation trench construction is completed on site, the precast base plate is first hoisted according to the positioning. Waterproof rubber strips (elastic rubber waterproof strips, water-swellable waterstop strips, butyl putty composite strips or other forms of waterproof strips can also be used) are installed in the groove of the base plate. Preferably, the waterproof rubber strip protrudes 10-20mm from the bottom surface of the groove. Waterproof mortar or silicone waterproof adhesive can be used to fill the edges to strengthen the structural connection and waterproof the structure.

[0022] After the precast base slab is installed, the precast wall panels are installed, so that the key at the bottom of the precast wall panel is embedded into the groove of the precast base slab. At this time, the pre-embedded steel plate at the bottom of the wall panel and the pre-embedded steel plate of the base slab are attached and welded together. The welding can be continuous or intermittent. After the precast wall panel is installed, the waterproof rubber strip embedded in the groove of the precast base slab is squeezed and compacted, which can achieve a good waterproof effect.

[0023] Each prefabricated wall panel is installed sequentially, and the connection between adjacent prefabricated wall panels is achieved by welding the pre-embedded steel plates at the ends of the adjacent prefabricated wall panels.

[0024] After the precast wall panels are installed, precast roof slabs and precast inspection wells are installed on top of them. The connection between the precast roof slab and the precast wall panels can be made directly after grouting on the top of the precast wall panels. Similarly, the connection between the precast roof slab and the precast inspection wells can also be made by grouting. In addition, steel plates can be pre-embedded at the contact points of each component for welding connection.

[0025] After all parts are welded and installed, the connecting steel plates should be treated with anti-corrosion measures.

[0026] After the joints of each panel are sealed tightly, backfill the soil, and fill the surrounding area evenly with soil. Finally, the construction is completed.

[0027] In addition to ordinary concrete, the materials used for each precast component can also be UHPC ultra-high performance concrete or other materials.

[0028] Components are generally connected by welding, but bolting or other mechanical connections may also be used.

[0029] As an improvement to the technical solution, such as Figure 3 As shown, the groove 11 is in the shape of an inverted trapezoid.

[0030] As an improvement to the technical solution, the precast wall panel 2 includes precast side wall panels and precast end wall panels, as shown in Figure 1. The precast wall panel 2 is formed by connecting two precast side wall panels and two precast end wall panels.

[0031] As an improvement to the technical solution, the precast roof slab 3 and the precast wall panel 2 are connected by welding or grouting through embedded steel plates.

[0032] As an improvement to the technical solution, the prefabricated inspection well 4 and the prefabricated top plate 3 are connected by welding or grouting through pre-embedded steel plates.

[0033] The specific embodiments of this utility model are written in a progressive manner, emphasizing the differences between each implementation scheme, and the similar parts can be referred to each other.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
