Description

Technical Field

[0001] The present invention relates to the technical field of river channel slope protection, and in particular to a river channel assembled slope protection and construction method based on BIM technology. Background Art

[0002] River bank protection is designed to prevent erosion. Various paving and planting methods are used on the slopes. As the concave banks of the river are subject to erosion year after year, they can cause continuous collapse. To protect bridges and embankments, protective structures are often constructed on the concave banks. These structures are commonly constructed using riprap, dry-laid stone, mortared stone, gabions, and stilts. Modern industrial building design often utilizes BIM technology, using relevant project data as the foundation for the model. This model is then constructed, simulating the real-world information of the building through digital information simulation.

[0003] In the prior art, when constructing existing river bank protection, a wire mesh is often directly placed on the edge of the slope, and then concrete is directly poured on the surface of the wire mesh to form a slope protection structure at the edge of the river. Taking concrete as an example, concrete is completely supported by the wire mesh. When laying, it is easily affected by the soil at the edge. The soil is soft and requires repeated construction to ensure the stability of the construction. Summary of the Invention

The upper ends of the two support shafts 2 are fitted with the inclined surface. Specifically, the first connecting shaft 19 and the second connecting shaft 20 are rotatably connected, so that the angles of the first support shaft 1 and the second support shaft 2 relative to the mounting frame 5 can be changed, so that the relative angles can be adjusted according to the actual situation of the river channel. The position of the first connecting shaft 19 and the mounting frame 5 is fixed by the threaded shaft 18. The connection method of the threaded shaft can avoid left and right deviation during use. A plurality of nuts 24 are also threadedly sleeved on the threaded shaft 18. The nuts 24 fit with the surface of the first connecting shaft 19. By adding nuts 24 to the threaded shaft 18, the nuts 24 are abutted against the surface of the first connecting shaft 19, thereby further reinforcing the position of the first connecting shaft 19.

[0033] In the above embodiment, the mounting mechanism of the present invention includes an I-shaped card block 17, a card slot 16 is provided on the mounting frame 5, and the I-shaped card block 17 is connected to the card slot 16 of the two mounting frames 5. The I-shaped card block 17 is also connected to two plug-in boards 22, and plug-in blocks are provided at both ends of the plug-in board 22. The two plug-in blocks are respectively inserted into the I-shaped card block 17 and the mounting frame 5. The I-shaped card block 17 is connected to the two mounting frames 5, and the I-shaped card block 17 is connected to the card slot 16. The I-shaped card block 17 is connected to the card slot 16 through the plug-in board 22.

One end of the L-shaped connecting block 23 is inserted into the mounting frame 5, and the other end is clamped with the side of the I-shaped card block 17. An L-shaped connecting block 23 is added to the I-shaped card block 17 to further strengthen the installation connection between the I-shaped card block 17 and the mounting frame 5 from the side position of the I-shaped card block 17.

[0034] The assembled slope protection provided by the above embodiment is used. First, according to the needs of building the river channel, a pad shaft 6 with an edge with a certain inclination angle is prepared according to the inclination angle of the concave bank of the river channel, and the installation frame 5 is built on the bank of the river channel. The two adjacent installation frames 5 are connected together through the installation mechanism, and the I-shaped card block 17 is clamped on the two adjacent card slots 16. The plug-in boards 22 are inserted on both sides of the I-shaped card block 17, and the two ends of the plug-in boards 22 are respectively clamped with the I-shaped card block 17 and the surface of the installation frame 5. Then, the two installation frames 5 are connected to the I-shaped card block 17, and the two installation frames 5 can be fixedly connected together. L-shaped connecting blocks 23 are also clamped on both sides of the I-shaped card block 17. One end of the L-shaped connecting block 23 is plugged into the installation frame 5, and the other end is clamped with the side of the I-shaped card block 17, so as to reinforce the position of the I-shaped card block 17 from the side.

[0035] Subsequently, a prefabricated pad shaft 6 with a certain inclined surface is installed on one side of the two installation frames 5 close to the river channel concave case, and a frame assembly is built along the inclined surface. The upper ends of the first support shaft 1 and the second support shaft 2 are fitted with the inclined surface. The upper ends of the first support shaft 1 and the second support shaft 2 are connected to the installation frame 5 through a connecting mechanism. The first connecting shaft 19 is directly snapped onto the surface of the installation frame 5 and the pad shaft 6. One end of the corner 25 of the first connecting shaft 19 will be located within the internal range of the installation frame 5. Screw from one side of the installation frame 5 The thread passes through the threaded shaft 18, and the threaded shaft 18 also threads through each first connecting shaft 19, thereby realizing the fixed connection between the first support shaft 1, the second support shaft 2 and the installation frame 5. Since a nut 24 is also threadedly installed on the threaded shaft 18 and fits with the side of the first connecting shaft 19, the position of the first connecting shaft 19 relative to the threaded shaft 18 is restricted. In the process of interlacing, the threaded shaft 18 can be interrupted in the non-connected space without affecting the connection effect, and then in a continuous river channel, multiple installation frames 5 can be continuously connected.

[0036] Among them, the first support shaft 1 and the second support shaft 2 are supported by the inclined shaft 3 and the auxiliary shaft 4. The two ends of the inclined shaft 3 are rotatably provided with plug shafts 13, and the two plug shafts 13 are respectively inserted into the corresponding holes of the first support shaft 1 and the second support shaft 2. The inclined inclined shaft 3 can form a triangular structure with the first support shaft 1 or the second support shaft 2, so that the overall structure is more stable and can withstand greater pressure. An auxiliary shaft 4 is also installed at the lower end of the inclined shaft 3. The inclined shaft 3 can be set in an inclined direction toward the first support shaft 1 or the second support shaft 2. The inclination direction of each inclined shaft 3 is different, avoiding multiple structures facing in one direction and avoiding a single force direction. The installation method with the extension lines intertwined with each other can withstand a larger range of forces when subjected to external pressure, and the structure is more stable. The two adjacent frame components are directly installed and connected through the connecting rod 7.

[0037] In order to further better explain the embodiments of the present invention, a construction method of river channel prefabricated slope protection based on BIM technology is also provided, comprising the following steps:

[0038] S1: When constructing the side of the river channel, the angle between the frame assembly and the installation box 5, as well as the length and size of each structure, were simulated using BIM technology;

[0039] S2: directly erecting the assembled segmented slope protection on the edge of the river channel, and assembling the segmented slope protection in sequence according to the length of the river channel edge;

[0040] S3: After the slope protection of each section is assembled, concrete is laid directly on its surface and it can be formed later.

[0041] In the above method, the assembled frame structure of the present invention is easier to bear concrete, is more convenient when laying, and is faster to form in the later stage.

[0042] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
