Description

Technical Field

[0001] This utility model relates to the field of concrete channel technology, specifically a spliced ​​concrete channel. Background Technology

[0002] Concrete channels are waterways made of concrete used for drainage or water transport. They possess excellent durability, impact resistance, and impermeability, making them a very common building material in water conservancy projects. To improve on-site construction efficiency, prefabricated concrete channels are now often used instead of on-site pouring, which can significantly increase construction speed and shorten the construction period.

[0003] The utility model with announcement number CN206721850U discloses a precast concrete channel component. When two such precast concrete channel components are connected together, the first connecting plate abuts against the second connecting plate, and the first locking strip is embedded in the first locking groove and the second locking strip is embedded in the second locking groove. This allows the two component bodies to be spliced ​​together, and the gaps during splicing are very tight, making the channel less prone to leakage.

[0004] In the above-mentioned fasteners, after the two precast channel components are spliced ​​together, concrete is poured into the cavity to achieve a fixed connection between the two precast components. Due to the small area of ​​the connecting cavity and the lack of auxiliary anti-bending measures, the connection strength at the connection is not high enough. It is easy to break at the connection when the channel is impacted or the foundation undergoes local settlement, resulting in damage to the channel and rendering it unusable. Therefore, in order to address the above problems, a spliced ​​concrete channel is proposed. Utility Model Content

[0005] The technical problem this utility model aims to solve is to provide a spliced ​​concrete channel in which two channel sections are spliced ​​together by a lower connecting plate and an upper connecting plate at the ends, forming a large-volume grouting connection cavity after overlapping. Simultaneously, during splicing, the insert plate on the lower connecting plate is inserted into the receiving plate of the upper connecting plate. Since there are several sets of insert plates and receiving plates with different orientations, the bending resistance of the connection point can be significantly improved. When the grouting connection cavity is filled with concrete, the concrete firmly bonds to the lower connecting plate, insert plate, upper connecting plate, and receiving plate, forming a stable steel-concrete composite structure. This results in high strength at the connection point, making it less prone to breakage during use. This solves the technical problem in comparative technologies where the area of ​​the connection cavity at the splicing point of precast channel components is small and lacks auxiliary bending resistance measures, resulting in insufficient strength at the connection point and susceptibility to breakage at the connection point when the channel is impacted or the foundation experiences local settlement.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] A spliced ​​concrete channel includes a U-shaped channel section with a lower connecting plate and an upper connecting plate anchored at both ends. Both the lower and upper connecting plates have L-shaped cross-sections of the same size. When the two plates overlap, a grouting connection cavity is formed between them. The lower connecting plate contains several symmetrically arranged insert plates, and the upper connecting plate contains several symmetrically arranged receiving plates. The insert plates and receiving plates are interlocked. Two channel sections are spliced ​​together via the lower and upper connecting plates at their ends. Furthermore, after overlapping, a large-volume grouting connection cavity is formed. Simultaneously, during splicing, the insert plate on the lower connecting plate will be inserted into the receiving plate of the upper connecting plate. Since there are several sets of insert plates and receiving plates with different directions, the bending resistance of the connection can be significantly improved. When the grouting connection cavity is filled with concrete, the concrete will firmly bond with the lower connecting plate, insert plate, upper connecting plate, and receiving plate, forming a stable steel-concrete composite structure, which makes the connection have high strength and is not easy to break at the connection during use.

[0008] In one possible implementation, the lower connecting plate includes a lower anchor plate anchored to the end of the channel section, on which a lower enclosure plate is welded. In the above structural form, the lower anchor plate is used to anchor the lower enclosure plate to the end of the channel section, the lower enclosure plate is used to enclose and form a grouting connection cavity, and the end of the channel section is connected to a protective layer covering the outer surface of the lower enclosure plate. The protective layer is used to protect the lower enclosure plate and prevent it from rusting.

[0009] In one possible implementation, the upper connecting plate includes an upper anchor plate anchored to the end of the channel section, on which an upper surrounding plate is welded. In the above structural form, the upper anchor plate is used to anchor the upper surrounding plate to the end of the channel section, the upper surrounding plate is used to enclose and form a grouting connection cavity, and the end of the channel section is connected to a protective layer covering the outer surface of the upper surrounding plate. The protective layer is used to protect the lower surrounding plate and prevent it from rusting.

[0010] In one possible implementation, the main body of the plug-in plate is a plug-in plate body with a through first through hole. The receiving plate is composed of a set of plates with a plug-in groove that matches the size of the plug-in plate body. The plates are provided with a second through hole that communicates with the first through hole. Based on the above structure, the receiving plate and the plug-in plate can be firmly connected, thereby playing a role in resisting bending. The first through hole and the second through hole can ensure the overall connectivity of the grouting connection cavity, which is convenient for continuous concrete grouting.

[0011] In one possible implementation, a grouting hole is provided at the end of the channel section, which passes through the protective layer and the upper shroud in sequence and is connected to the middle of the grouting connection cavity. The opening of the grouting hole provides the necessary structural foundation for the grouting of concrete. At the same time, since it is opened at a low point, the concrete will overcome its own gravity and surge upward when grouting, thereby ensuring the density of the grouting concrete and making it less likely to have cavities.

[0012] In one possible implementation, grout outlet holes are provided at the top of both sides of the channel section, which pass through the protective layer and the upper shroud in sequence, and are connected to both sides of the grouting connection cavity. As concrete is continuously poured in, the air in the cavity will be discharged from the grout outlet holes, until concrete gushes out of the grout outlet holes, indicating that the grouting connection cavity is filled.

[0013] In one possible implementation, the inner wall of the lower connecting plate is welded with several lower protruding ribs arranged along the length direction, and the inner wall of the upper connecting plate is welded with several upper protruding ribs arranged along the length direction. The lower and upper protruding ribs can respectively enhance the structural strength of the lower and upper connecting plates, and at the same time enhance the bonding effect with concrete and improve the structural strength of the connection. In addition, a triangular reinforcing rib is provided at the corner of the channel bottom. This structural form can enhance the strength of the channel section at the bend and prevent it from breaking at the bend.

[0014] In one possible implementation, both the lower connecting plate and the upper connecting plate are anchored to the end of the channel section by anchoring rods welded to the end. Correspondingly, the end of the channel section is provided with an end groove and an anchoring groove. The above structure provides the necessary structural foundation for the anchoring connection of the lower connecting plate and the upper connecting plate.

[0015] In summary, this utility model has the following beneficial technical effects:

[0016] In this concrete channel, two channel sections are spliced ​​together by lower and upper connecting plates at their ends, forming a large-volume grouting connection cavity after overlapping. During splicing, the insert plate on the lower connecting plate is inserted into the receiving plate of the upper connecting plate. Since there are several sets of insert plates and receiving plates with different directions, the bending resistance of the connection can be significantly improved. When the grouting connection cavity is filled with concrete, the concrete will firmly bond with the lower connecting plate, insert plate, upper connecting plate, and receiving plate, forming a stable steel-concrete composite structure, which gives the connection high strength and makes it less prone to breakage at the connection during use.

[0024] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0025] like Figure 1 - Figure 2 As shown, this embodiment provides a spliced ​​concrete channel, including a channel section 1, which is U-shaped and has a lower connecting plate 2 and an upper connecting plate 3 anchored at both ends, respectively. Both the lower connecting plate 2 and the upper connecting plate 3 have L-shaped cross-sections of the same size. After the two sections overlap, a grouting connection cavity 4 is formed between them. The lower connecting plate 2 has several symmetrically arranged insert plates 21 fixedly installed inside, and the upper connecting plate 3 has several symmetrically arranged receiving plates 31 fixedly installed inside. The insert plates 21 and the receiving plates 31 are connected by insertion. The two channel sections 1 are connected by the lower connecting plate 2 and the upper connecting plate 3 at their ends. The plates 3 are spliced ​​together, and after overlapping, they form a large-volume grouting connection cavity 4. At the same time, during splicing, the insert plate 21 on the lower connecting plate 2 will be inserted into the receiving plate 31 of the upper connecting plate 3. Since there are several sets of insert plates 21 and receiving plates 31 with different directions, the bending resistance of the connection can be significantly improved. When the grouting connection cavity 4 is filled with concrete, the concrete will be firmly bonded to the lower connecting plate 2, insert plate 21, upper connecting plate 3, and receiving plate 31, forming a stable steel-concrete structure, which makes the connection have high strength and is not easy to break at the connection during use.

[0026] like Figure 4As shown, the lower connecting plate 2 includes a lower anchor plate 201 anchored to the end of the channel section 1, on which a lower enclosure plate 202 is welded. In the above structure, the lower anchor plate 201 is used to anchor the lower enclosure plate 202 to the end of the channel section 1, and the lower enclosure plate 202 is used to enclose and form the injection connection cavity 4. The end of the channel section 1 is connected to a protective layer 12 covering the outer surface of the lower enclosure plate 202. The protective layer 12 is used to protect the lower enclosure plate 202 and prevent it from rusting.

[0027] like Figure 3 As shown, the upper connecting plate 3 includes an upper anchor plate 301 anchored to the end of the channel section 1, on which an upper surrounding plate 302 is welded. In the above structure, the upper anchor plate 301 is used to anchor the upper surrounding plate 302 to the end of the channel section 1, and the upper surrounding plate 302 is used to enclose and form the injection connection cavity 4. The end of the channel section 1 is connected to a protective layer 12 covering the outer surface of the upper surrounding plate 302. The protective layer 12 is used to protect the lower surrounding plate 202 and prevent it from rusting.

[0028] like Figure 3 - Figure 4 As shown, the main body of the plug-in plate 21 is the plug-in plate body 211, which has a through first through hole 212. The receiving plate 31 is composed of a set of mating plates 311, with a plug-in groove 312 formed between them that matches the size of the plug-in plate body 211. The mating plates 311 have a second through hole 313 that communicates with the first through hole 212. Based on the above structural form, the receiving plate 31 and the plug-in plate 21 can be firmly connected, thereby playing a role in resisting bending. The first through hole 212 and the second through hole 313 can ensure the overall connectivity of the grouting connection cavity 4, which is convenient for continuous concrete grouting.

[0029] like Figure 1 - Figure 3 As shown, a grouting hole 5 is provided at the end of the channel section 1, which passes through the protective layer 12 and the upper circumferential plate 302 in sequence, and is connected to the middle of the grouting connection cavity 4. The opening of the grouting hole 5 provides the necessary structural foundation for the grouting of concrete. At the same time, since it is opened at a low point, the concrete will overcome its own gravity and surge upward when grouting, thereby ensuring the density of the grouting concrete and making it less likely to have cavities.

[0030] like Figure 3 As shown, grout outlet holes 6 are provided on the top of both sides of channel section 1. They pass through the protective layer 12 and the upper circumferential plate 302 in sequence and are connected to both sides of the grouting connection cavity 4. As concrete is continuously poured in, the air in the cavity will be discharged from the grout outlet holes 6. When concrete gushes out of the grout outlet holes 6, it means that the grouting connection cavity 4 is filled.

[0031] like Figure 3 - Figure 4As shown, the inner wall of the lower connecting plate 2 is welded with several lower protruding ribs 22 arranged along the length direction, and the inner wall of the upper connecting plate 3 is welded with several upper protruding ribs 32 arranged along the length direction. The lower protruding ribs 22 and the upper protruding ribs 32 can respectively enhance the structural strength of the lower connecting plate 2 and the upper connecting plate 3, and at the same time enhance the bonding effect with concrete and improve the structural strength of the connection. In addition, a triangular reinforcing rib 11 is provided at the corner of the channel bottom of the channel section 1. This structural form can enhance the strength of the bend of the channel section 1 and prevent it from breaking at the bend.

[0032] like Figure 5 As shown, both the lower connecting plate 2 and the upper connecting plate 3 are anchored to the end of the channel section 1 by the anchor rods 7 welded to the end. Correspondingly, the end of the channel section 1 is provided with an end groove 13 and an anchor groove 14. The above structure provides the necessary structural foundation for the anchoring connection of the lower connecting plate 2 and the upper connecting plate 3.

[0033] The working principle and usage process of this utility model:

[0034] In this concrete channel, two channel sections 1 are spliced ​​together by a lower connecting plate 2 and an upper connecting plate 3 at their ends, forming a large-volume grouting connection cavity 4 after overlapping. At the same time, during splicing, the insert plate 21 on the lower connecting plate 2 is inserted into the receiving plate 31 of the upper connecting plate 3. Since there are several sets of insert plates 21 and receiving plates 31 with different directions, the bending resistance of the connection can be significantly improved. When the grouting connection cavity 4 is filled with concrete, the concrete will firmly bond with the lower connecting plate 2, insert plate 21, upper connecting plate 3, and receiving plate 31, forming a stable steel-concrete structure, which makes the connection have high strength and is not easy to break at the connection during use.

[0035] In addition, the inner wall of the lower connecting plate 2 is welded with several lower protruding ribs 22 arranged along the length direction, and the inner wall of the upper connecting plate 3 is welded with several upper protruding ribs 32 arranged along the length direction. The lower protruding ribs 22 and the upper protruding ribs 32 can respectively enhance the structural strength of the lower connecting plate 2 and the upper connecting plate 3, and at the same time enhance the bonding effect with concrete and improve the structural strength of the connection. In addition, a triangular reinforcing rib 11 is provided at the corner of the channel bottom of the channel section 1. This structural form can enhance the strength of the bend of the channel section 1 and prevent it from breaking at the bend.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
