Abstract
Description
Technical Field
[0001] This utility model relates to the field of flow barrier technology, specifically to a cast-in-place-prefabricated combined flow barrier structure. Background Technology
[0002] In hydraulic engineering, flow barriers are key structures for regulating water flow, preventing scouring, and improving flow patterns. Traditional flow barriers mainly employ cast-in-place concrete structures or fully prefabricated assembly structures, but both have certain technical limitations. For traditional cast-in-place structures: the construction period for cast-in-place flow barriers is relatively long, requiring on-site formwork erection, rebar tying, concrete pouring, and curing. This construction method is greatly affected by the site environment; low temperatures, rainfall, and other adverse weather conditions can all affect the construction progress. Furthermore, because the connection between the flow barrier and the berthing pier is an irregular structure, the reuse rate of cast-in-place formwork is low, resulting in significant waste. For fully prefabricated assembly structures: the bottom prefabricated structure needs to bear its own weight and the vertical load of the upper prefabricated components, and its dimensions are usually large. However, the high requirements for transportation and lifting equipment for large prefabricated components lead to limitations in the size of the prefabricated components. Additionally, the bottom prefabricated structure is difficult to adapt to complex terrain or special flow pattern requirements.
[0003] Chinese patent application number 202322675325.7 discloses a piling-lined flow barrier mooring structure, comprising multiple mooring units connected sequentially from upstream to downstream. Each mooring unit includes a flow barrier structure, a mooring mechanism, and two mooring piers arranged opposite each other along the water flow direction. The flow barrier structure includes a flow barrier body, a lining, and a cap beam. The flow barrier body is connected between the two mooring piers, the lining is located on top of the flow barrier body, and the cap beam is connected above the lining. The top of the flow barrier body extends out of the lining and is embedded in the cap beam. The mooring mechanism includes a first mooring bollard and multiple second mooring bollards. Multiple mounting grooves are recessed inward on the side wall of the mooring piers, the second mooring bollards are fixedly installed in the mounting grooves, and the first mooring bollards are fixed to the top of the mooring piers. This piling-lined flow barrier mooring structure has the following shortcomings: 1) The main body of the flow barrier wall includes multiple pile foundations arranged side by side at intervals. On the one hand, the pile foundations need to be vertically cast in place, which results in a long construction period and low reuse rate. On the other hand, the pile foundations in the middle do not form an effective connection with the berthing pier, resulting in poor overall strength. 2) The overall structural design is not reasonable and the construction effect needs to be improved. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a cast-in-place-precast composite flow barrier structure that is easy to assemble and disassemble, speeds up the construction progress, and improves the reusability and overall strength.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A cast-in-place-precast combined flow barrier structure includes multiple spaced berthing piers, with a cast-in-place base wall between the bottoms of adjacent berthing piers. Above the cast-in-place base wall are multiple standard precast blocks stacked sequentially from bottom to top. Vertical grooves are provided on opposite sides of adjacent berthing piers. The two ends of the standard precast blocks are inserted into the opposite vertical grooves of adjacent berthing piers. A top precast block is placed on the topmost standard precast block, with the two ends of the top precast block inserted into the opposite vertical grooves of adjacent berthing piers. A walking plane is formed on the top surface of the top precast block.
[0006] As a further improvement to the above technical solution: The standard precast block has grooves and protrusions on its upper and lower surfaces, respectively, and the opposite sides of adjacent standard precast blocks are engaged by the grooves and protrusions.
[0007] The grooves and protrusions are shaped to fit each other.
[0008] The grooves and protrusions both have trapezoidal cross-sections.
[0009] The groove is located on the lower surface of the standard precast block, and the protrusion is located on the upper surface of the standard precast block.
[0010] The lower surface of the top precast block is provided with an insert, which is embedded in a corresponding groove.
[0011] The top of the precast block is provided with an outwardly protruding platform, the top surface of which is flush with the walking plane.
[0012] The top of the berth is provided with a slot for the outer suspension platform to be inserted, and the end of the outer suspension platform is inserted into the corresponding slot.
[0013] The top surface of the outer suspension platform is flush with the top surface of the berth.
[0014] The end face of the standard precast block has an inclined stepped surface, and the bottom surface of the vertical groove is adapted to the end face of the standard precast block.
[0015] Compared with the prior art, the advantages of this utility model are: This utility model discloses a cast-in-place / precast combined flow barrier structure. First, a cast-in-place base wall is formed between the bottoms of adjacent berthing piers. On the one hand, this can adapt to complex terrain or special flow conditions; on the other hand, it provides stable support for the superstructure, which is beneficial for maintaining the overall vertical load. Second, each standard precast block and the top precast block are installed by inserting them from top to bottom into the corresponding vertical grooves of the adjacent berthing piers. Conversely, they can be removed by pulling them out from the corresponding vertical grooves of the adjacent berthing piers from bottom to top. On the one hand, this facilitates disassembly and assembly, speeds up the construction progress, and improves the reuse rate. On the other hand, the standard precast blocks and the top precast blocks are embedded in the vertical grooves to form an integral structure with the adjacent berthing piers, which improves the overall strength.

[0025] Figures 1 to 4 This invention illustrates an embodiment of the cast-in-place-precast combined flow barrier structure. The cast-in-place-precast combined flow barrier structure of this embodiment includes multiple spaced-apart piers 1. A cast-in-place base wall 2 is provided between the bottoms of adjacent piers 1. Above the cast-in-place base wall 2, multiple standard precast blocks 3 are stacked sequentially from bottom to top. Vertical grooves 4 are provided on opposite sides of adjacent piers 1. The two ends of the standard precast blocks 3 are respectively inserted into the opposite vertical grooves 4 of adjacent piers 1. A top precast block 5 is placed on the topmost standard precast block 3. The two ends of the top precast block 5 are respectively inserted into the opposite vertical grooves 4 of adjacent piers 1. A walking plane 6 is formed on the top surface of the top precast block 5.
[0026] This cast-in-place and precast composite flow barrier structure has two main features. First, a cast-in-place base wall 2 is formed between the bottoms of adjacent berths 1. This allows it to adapt to complex terrain or special flow conditions and provides stable support for the superstructure, helping to maintain the overall vertical load. Second, each standard precast block 3 and the top precast block 5 are installed by inserting them from top to bottom into the corresponding vertical grooves 4 of the adjacent berths 1. Conversely, they can be removed by pulling them out from the corresponding vertical grooves 4 of the adjacent berths 1 from bottom to top. This facilitates disassembly and assembly, speeds up construction, and increases the reuse rate. Furthermore, the standard precast blocks 3 and the top precast blocks 5 are embedded in the vertical grooves 4 to form an integral structure with the adjacent berths 1, improving the overall strength.
[0027] Furthermore, such as Figure 3 As shown, in this embodiment, grooves 31 and protrusions 32 are respectively provided on the upper and lower surfaces of the standard precast block 3, and the opposite sides of adjacent standard precast blocks 3 are engaged by the grooves 31 and protrusions 32. The engagement of the opposite sides of adjacent standard precast blocks 3 by the grooves 31 and protrusions 32 further improves the overall strength.
[0028] Furthermore, in this embodiment, the groove 31 and the protrusion 32 are shaped to match. Preferably, the groove cross-section of both the groove 31 and the protrusion 32 is trapezoidal, which facilitates insertion and mating.
[0029] Furthermore, in this embodiment, the groove 31 is disposed on the lower surface of the standard precast block 3, and the protrusion 32 is disposed on the upper surface of the standard precast block 3. Of course, in other embodiments, the groove 31 may be disposed on the upper surface of the standard precast block 3, and the protrusion 32 may be disposed on the lower surface of the standard precast block 3.
[0030] Furthermore, in this embodiment, the lower surface of the top prefabricated block 5 is provided with an insert 51, which is embedded in the corresponding groove 31. The insert 51 has the same shape as the protrusion 32.
[0031] Furthermore, in this embodiment, the top of the top prefabricated block 5 is provided with an outwardly protruding outer suspension platform 7, the top surface of which is flush with the walking plane 6, thereby increasing the width of the walking plane 6.
[0032] Furthermore, in this embodiment, the top of the pier 1 is provided with a slot 11 for the outer suspension platform 7 to be inserted, and the end of the outer suspension platform 7 is inserted into the corresponding slot 11.
[0033] Furthermore, in this embodiment, the top surface of the outer suspension platform 7 is flush with the top surface of the berthing pier 1.
[0034] Furthermore, in this embodiment, the end face of the standard precast block 3 has an inclined stepped surface 8, and the bottom surface of the vertical groove 4 is adapted to the end face of the standard precast block 3, that is, the bottom surface of the vertical groove 4 is also provided with an inclined stepped surface 8, which can increase the contact area and thus improve the fitting effect.
[0035] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention.
