Technical Field
[0001] This utility model relates to the field of power installation equipment technology, and in particular to a prefabricated foundation structure for a booster station. Background Technology
[0002] In the field of substation construction, prefabricated modules serve as important carriers for integrated electrical equipment, and the stability and reliability of their foundation structure directly affect the safe operation of the entire substation. Pile foundations and raft foundations are commonly used foundation types for prefabricated modules in substations. Pile foundations can transfer loads to deep, stable soil layers and are suitable for complex geological conditions such as soft foundations; raft foundations, with their larger bottom area, effectively distribute loads and enhance the overall integrity of the foundation.
[0003] The existing precast slab foundation structure involves first driving pile foundations into the ground, then binding steel mesh to the pre-reserved steel bars above multiple pile foundations, supporting a protective slab around the steel mesh, and finally pouring concrete into the space inside the protective slab. After the concrete hardens, the concrete and steel mesh form a raft foundation. The construction process is complicated and the overall construction period is relatively long. Utility Model Content
[0004] This utility model provides a prefabricated foundation structure for a booster station, solving the problems of complicated construction procedures and long overall construction cycle mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated substation foundation structure, comprising a raft slab, crossbeams, piles, limiting sliders, and insert rods. Multiple crossbeams are evenly arranged at the lower end of the raft slab. Each crossbeam has an insertion port at both ends of its lower surface. Sliding slider grooves are formed on the inner sides of each insertion port. Insertion holes are formed through the sides of both ends of the crossbeams. A sliding block is fixedly connected to the upper end of each pile. The sliding block is inserted into the insertion port. Two limiting sliders are slidably connected inside the sliding block. One side of each limiting slider is an arc-shaped surface. The two limiting sliders are symmetrically arranged, with their arc-shaped surfaces facing each other. A seat hole is formed through the side of the sliding block, and the seat hole corresponds to the insertion hole. The insert rod is inserted through the seat hole of each pile in the same row and into the insertion hole of the corresponding crossbeam of each pile. The limiting slider is located in the sliding slider groove.
[0006] Preferably, the upper surface of the raft plate has an opening.
[0007] Preferably, both ends of the raft are fixedly connected to lifting rings, and the two lifting rings at the same end are symmetrically arranged.
[0008] Preferably, the socket extends through the socket.
[0009] Preferably, the upper surface of the slide block is provided with a through groove, and the limiting slider is disposed in the through groove.
[0010] Preferably, a sliding groove is formed on the inner side of the through groove, and a sliding strip is fixedly connected to the side of the limiting slider. The sliding strip is located in the sliding groove, and the limiting slider is slidably connected to the sliding groove through the sliding strip.
[0011] Preferably, a mounting groove is provided on one side of the slide bar, the mounting groove is located on the same side as the slide bar, and the mounting groove is formed through the limiting slider.
[0012] Preferably, a slurry outlet is provided on the opposite side of the arc-shaped surface of the limiting slider, and the slurry outlet is connected to the mounting groove.
[0013] Preferably, the two sides of the insertion hole are provided with pipe grooves, which are opened through the crossbeam. The grouting pipe is inserted through the pipe grooves of the multiple crossbeams arranged in a row and into the placement groove of the limiting slider provided on the corresponding column pile of each crossbeam.
[0014] Preferably, the side of the grouting pipe is provided with a side opening, the side opening is positioned corresponding to the grout outlet, and the grout outlet is located in the slider groove.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. Using hoisting equipment, smoothly hoist the raft slab, with the bottom beam already fixed, onto the piles. Precisely align the insertion ports at both ends of the lower surface of the beam with the sliding blocks at the upper end of the pile, and slowly lower the raft slab, allowing the sliding blocks to smoothly insert into the insertion ports. At this point, the beam and pile are initially connected, laying the foundation for subsequent reinforcement operations. Then, align the insertion rod with the seat holes of the piles in the same row and the corresponding insertion holes of the beam, and begin the insertion operation. When the insertion rod contacts the opening at the contact point of the two opposing arc-shaped surfaces of the limiting sliders, the insertion process will trigger the movement mechanism of the limiting sliders. One end of the insertion rod slides along the arc-shaped surface of the limiting slider. Due to the special curved surface structure design, under the thrust of the insertion rod, the two limiting sliders on the sliding block are pushed to slide and separate along the grooves on both sides, ultimately precisely entering the corresponding slider grooves on both sides. At this point, the limiting sliders exert a strong restraining effect on the raft slab in the vertical direction.
[0017] 2. Insert the grouting pipes sequentially into the slots of the crossbeam and the mounting slots of the limiting slider, ensuring that the side openings of the grouting pipes precisely correspond to the grout outlets on the limiting sliders. Inject concrete grout into the connection area through the grouting pipes. The grout flows out from the side openings and evenly fills the slider slots and the connection gaps between the crossbeam and the column pile through the grout outlets. As the concrete grout gradually solidifies, it tightly bonds the crossbeam, column pile, and limiting slider into a whole, further enhancing the load-bearing capacity and integrity of the foundation structure, and effectively improving the stability and reliability of the foundation structure under complex working conditions. This completes the construction of the prefabricated substation foundation structure. This simplifies the construction process, reduces construction steps and waiting time, and significantly shortens the overall construction cycle. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0032] This utility model provides a prefabricated foundation structure for a booster station, such as... Figure 1 and Figure 2 As shown, it includes a raft slab 1, crossbeams 2, piles 3, limiting sliders 4, and insert rods 5. Multiple crossbeams 2 are evenly distributed at the lower end of the raft slab 1, as shown... Figure 3 As shown, both ends of the lower surface of the crossbeam 2 are provided with sockets 21, and the two inner sides of the sockets 21 are provided with sliding grooves 211. The two sides of the crossbeam 2 are provided with through holes 22, which pass through the sockets 21. A sliding block 31 is fixedly connected to the upper end of the column pile 3, and the sliding block 31 is inserted into the socket 21. The sockets 21 and sliding grooves 211 achieve precise connection with the column pile 3. The through holes 22, together with the insertion rod 5, enhance the connection stability. The pipe groove 23 provides an installation channel for the grouting pipe 6, allowing concrete grout to be accurately injected into the connection, effectively improving the integrity and load-bearing capacity of the foundation structure. Furthermore, the crossbeam 2's arrangement rationally distributes the load transfer path between the column pile 3 and the raft slab 1, optimizing the stress performance of the foundation structure. Figure 8 and Figure 9 As shown, two limiting sliders 4 are slidably connected inside the slide block 31. One side of each limiting slider 4 is an arc-shaped surface. The two limiting sliders 4 are symmetrically arranged, with their arc-shaped surfaces facing each other. A seat hole 313 is provided through the side of the slide block 31, and the seat hole 313 corresponds to the position of the insertion hole 22. Figure 4 and Figure 5As shown, the insert rod 5 is inserted through the seat hole 313 of the column pile 3 in the same row and the insertion hole 22 of the corresponding crossbeam 2 of each column pile 3, with the limiting slider 4 located in the slider groove 211. The column pile 3 extends deep into the ground to transfer the load and ensure the vertical stability of the foundation. The sliding seat 31 is fixedly connected to the column pile 3, and the internally designed limiting slider 4 sliding structure, in conjunction with the insertion hole 21 and slider groove 211 of the crossbeam 2, achieves a quick and accurate connection with the crossbeam 2, reducing construction steps and improving construction efficiency.
[0033] like Figure 7 As shown, one end of the insertion rod 5 is fixedly connected to an end cap 51, and the other end of the insertion rod 5 is threaded with a fixing nut. The insertion rod 5 rigidly connects the crossbeam 2 and the column pile 3 through the seat hole 313 and the insertion hole 22. The design of the end cap 51 and the fixing nut ensures that the insertion rod 5 is installed accurately and firmly, preventing loosening of the connection and improving the stability and reliability of the foundation structure. The use of the insertion rod 5 replaces the traditional and complex steel bar binding process, simplifying the construction process and shortening the construction cycle.
[0034] like Figure 1 and Figure 2 As shown, an opening is provided on the upper surface of the raft slab 1. Lifting rings 11 are fixedly connected to both ends of the raft slab 1, with two lifting rings 11 symmetrically arranged at the same end. The prefabricated substation module can be placed in the opening of the raft slab 1. The lifting rings 11 facilitate the hoisting and transportation of the raft slab 1, improving construction efficiency, while their symmetrical arrangement ensures balance and safety during the hoisting process.
[0035] like Figure 10 and Figure 11 As shown, a through groove 311 is formed on the upper surface of the slide block 31, and the limiting slider 4 is disposed in the through groove 311. A sliding groove 312 is formed on the inner side of the through groove 311, and a slide bar 41 is fixedly connected to the side of the limiting slider 4. The slide bar 41 is located in the sliding groove 312, and the limiting slider 4 is slidably connected to the sliding groove 312 through the slide bar 41. A mounting groove 42 is provided on one side of the slide bar 41. The mounting groove 42 is located on the same side as the slide bar 41, and the mounting groove 42 is formed through the limiting slider 4.
[0036] The slider 41 is located on the longer of the two sides of the limit slider 4 that are connected to the arc surface.
[0037] like Figure 5 and Figure 12 As shown, a slurry outlet 43 is provided on the opposite side of the arc-shaped surface of the limiting slider 4, and the slurry outlet 43 is connected to the mounting groove 42. Pipe grooves 23 are provided on both sides of the insertion hole 22, and the pipe grooves 23 are formed through the crossbeam 2, as shown. Figure 6 and Figure 7As shown, the grouting pipe 6 is inserted into the pipe groove 23 of the multiple beams 2 arranged in a row, and into the placement groove 42 of the limiting slider 4 set on the corresponding column pile 3 of each beam 2. The side opening 61 of the grouting pipe 6 is opened, and the position of the side opening 61 corresponds to the grout outlet 43, which is located in the slider groove 211. The limiting slider 4 slides under the action of the insertion rod 5 and enters the corresponding slider groove 211 on both sides. The design of the placement groove 42 and the grout outlet 43, together with the grouting pipe 6, allows the concrete grout to fully fill the joint gap, further improving the strength of the connection, while enhancing the integrity and durability of the foundation structure. The grouting pipe 6 is accurately inserted into the connection part through the pipe groove 23 and the placement groove 42, and the side opening 61 corresponds to the grout outlet 43, ensuring that the concrete grout can be evenly injected into the joint gap between the beam 2 and the column pile 3. Grouting allows the components to be tightly bonded together by the solidified concrete, forming a whole. This effectively improves the load-bearing capacity and stability of the foundation structure, while simplifying the traditional concrete pouring process and increasing construction efficiency.
[0038] Using this utility model, such as Figure 1 and Figure 2As shown, the pile 3 is driven into the ground according to the design requirements, ensuring its depth and position are accurate. A structure with a sliding block 31 and a limiting slider 4 is installed at the upper end of the pile 3. The sliding block 31 is tightly fixed to the pile 3, and the limiting slider 4 can slide flexibly inside the sliding block 31, preparing for subsequent connection with the crossbeam 2. Next, using the lifting rings 11 symmetrically arranged at both ends of the raft slab 1, the raft slab 1, with the crossbeam 2 already fixed at its bottom, is smoothly lifted onto the pile 3 using hoisting equipment. The insertion slots 21 at both ends of the lower surface of the crossbeam 2 are precisely aligned with the sliding block 31 at the upper end of the pile 3, and the raft slab 1 is slowly lowered, allowing the sliding block 31 to smoothly insert into the insertion slots 21. At this point, the crossbeam 2 and the pile 3 are initially connected, laying the foundation for subsequent reinforcement operations. Then, the insertion rod 5 is aligned with the seat hole 313 of the same row of pile 3 and the corresponding insertion hole 22 of the crossbeam 2, and the insertion operation begins. When the insertion rod 5 contacts the opening at the point where the two limiting sliders 4 meet on their respective arc-shaped surfaces, the insertion of the insertion rod 5 will trigger the movement mechanism of the limiting sliders 4. One end of the insertion rod 5 slides along the arc-shaped surface of the limiting slider 4. Due to the special curved surface structure design, under the thrust of the insertion rod 5, according to the principle of force decomposition, this thrust will generate a component force along the sliding direction of the limiting slider 4. As the insertion rod 5 continues to be inserted, it pushes the two limiting sliders 4 on the slide block 31 to slide and separate to both sides along the slide groove 312, and they finally enter the corresponding slider grooves 211 on both sides precisely. At this time, the limiting sliders 4 form a strong restraining effect on the raft 1 in the vertical direction, preventing it from detaching from the column pile 3 in the vertical direction, thereby significantly enhancing the stability of the connection between the raft 1 and the column pile 3. When the insertion rod 5 protrudes from the other end of the raft slab 1, the fixing nut is quickly tightened, so that the end 51 is tightly abutted against one end of the raft slab 1, and the fixing nut is firmly abutted against the other end of the raft slab 1. The insertion rod 5 securely locks the beam 2 and the column pile 3, forming a rigid connection. After the insertion rod 5 is installed and fixed, the grouting reinforcement step is carried out. The grouting pipe 6 is inserted into the pipe groove 23 of the beam 2 and the placement groove 42 of the limiting slider 4 in sequence. By setting the size, it can be ensured that the side opening 61 of the grouting pipe 6 corresponds precisely to the grout outlet 43 on the limiting slider 4. Concrete grout is injected into the connection part through the grouting pipe 6. The grout flows out from the side opening 61 and evenly fills the slider groove 211 and the connection gap between the beam 2 and the column pile 3 through the grout outlet 43. As the concrete grout gradually solidifies, the beam 2, column pile 3 and limiting slider 4 are tightly bonded into a whole, further enhancing the load-bearing capacity and integrity of the foundation structure, and effectively improving the stability and reliability of the foundation structure under complex working conditions. This completes the construction of the prefabricated substation foundation structure. It addresses the problems of cumbersome and time-consuming construction procedures in traditional substation prefabricated substation foundation construction. Through the coordinated use of components such as piles 3, crossbeams 2, insert rods 5, limiting sliders 4, and grouting pipes 6, the construction process is simplified, construction steps and waiting time are reduced, and the overall construction cycle is significantly shortened.
[0039] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
