Description

Technical Field

[0001] This utility model relates to the field of riverbed paving technology, specifically to a riverbed paving structure that is resistant to erosion. Background Technology

[0002] In recent years, the country has promoted the construction of sponge cities. Riverbed paving, as an effective means to improve the water environment and restore the ecological function of rivers, aligns with the "water ecology" construction concept of sponge cities. Currently, there are many similar projects, but the riverbed paving structures used have some drawbacks. Traditional mortar-grouted rubble masonry structures have poor permeability, which is not conducive to the survival of microorganisms and other organisms, resulting in poor ecological performance; traditional interlocking brick structures have better permeability but poor erosion resistance. For areas such as estuaries affected by storm surges, where high erosion resistance of riverbed paving is required, a new type of erosion-resistant and environmentally friendly riverbed paving structure is urgently needed.

[0003] To address the aforementioned problems, we propose a erosion-resistant riverbed paving structure. Utility Model Content

[0004] To address the problems in the background art, this utility model provides a riverbed paving structure that is resistant to erosion.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A erosion-resistant riverbed paving structure includes a riverbed foundation. A longitudinal beam is provided at the center line of the riverbed foundation, and multiple transverse beams are distributed on the longitudinal beam. The longitudinal beam and transverse beams are combined to form a regular beam grid skeleton, and the beam grid skeleton is filled with interlocking bricks. The interlocking bricks are configured with an I-shaped structure. Both ends of the interlocking bricks are configured with locking blocks, and both sides of the interlocking bricks are configured with locking grooves. By tightly embedding the locking blocks into the locking grooves, multiple sets of interlocking bricks can be tightly assembled.

[0006] Preferably, the longitudinal beams and transverse beams are tightly connected to the connecting bricks on both sides by concrete pouring.

[0007] Preferably, the crossbeams and longitudinal beams are distributed vertically, and the multiple sets of crossbeams are spaced 30 meters apart.

[0008] Preferably, the riverbed foundation soil is compacted and then a cushion layer is applied, with a compaction coefficient ≥0.90.

[0009] In view of the problems existing in the current riverbed paving technology, the purpose of this utility model is to provide a riverbed paving structure that is erosion resistant, environmentally friendly, aesthetically pleasing, and requires low investment.

[0010] To achieve the above objectives, this utility model adopts a paving method using prefabricated I-shaped interlocking bricks and a beam grid framework. Specifically, the structure consists of I-shaped interlocking brick paving, which is tightly embedded to prevent loosening and washing away. To enhance the scour resistance of the paving during storm surges, reinforced concrete longitudinal and transverse beams are installed in the middle of the river channel to form a paving beam grid framework, reinforcing the interlocking brick paving.

[0011] Compared with existing conventional riverbed paving methods, this utility model has the following advantages; 1. Erosion resistant: The interlocking bricks are interlocked during installation to form a tight interlocking plane, which enhances cohesion and can effectively prevent loosening and washing away. At the same time, to further improve the erosion resistance, a concrete beam grid is set around the interlocking bricks to limit their position, which can effectively prevent the spread of paving damage. 2. Eco-friendly and environmentally friendly: Interlocking brick paving has relatively tight embedding and moderate permeability, but the use of precast concrete structure reduces the use of stone, resulting in better environmental performance and promoting the survival of microorganisms. 3. Flat and beautiful, low investment: The longitudinal and transverse beams form a regular beam grid framework. Interlocking bricks are laid inside the beam grid framework. After completion, the overall effect is flat and beautiful. The use of stone is reduced in the early stage. When maintaining and repairing later, only the damaged interlocking bricks can be replaced, which can greatly reduce maintenance costs. Attached Figure Description

[0014] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: Example: Refer to Figures 1-5The erosion-resistant riverbed paving structure of this embodiment includes a riverbed foundation 1, a longitudinal beam 3 is provided at the center line of the riverbed foundation 1, and multiple transverse beams 4 are distributed on the longitudinal beam 3. The longitudinal beam 3 and the transverse beams 4 are combined to form a regular beam grid skeleton 5, and the beam grid skeleton 5 is filled with interlocking bricks 6. The interlocking brick 6 is configured with an I-shaped structure. Both ends of the interlocking brick 6 are configured with a locking block structure 61, and both sides of the interlocking brick 6 are configured with a slot structure 62. By tightly embedding the locking block structure 61 into the slot structure 62, multiple sets of interlocking bricks 6 can be tightly assembled, forming a tightly embedded plane between the interlocking bricks 6, enhancing cohesion, and effectively preventing loosening and washing away.

[0015] In some examples, the longitudinal beam 3 and the transverse beam 4 are tightly connected to the connecting bricks on both sides by concrete pouring. During pouring, interlocking bricks 6 need to be laid first, and then the longitudinal beam 3 and transverse beam 4 are poured and shaped using the interlocking bricks 6 as templates. The shaped structure is referenced. Figure 5 As stated above.

[0016] In some examples, the crossbeams 4 and the longitudinal beams 3 are distributed vertically, and multiple sets of crossbeams 4 are spaced 30 meters apart.

[0017] In some examples, the riverbed foundation 1 soil is compacted before the subgrade 2 is laid, with a compaction coefficient ≥0.90.

[0018] In this utility model, when laying, the foundation soil of the riverbed foundation 1 is first compacted, then the cushion layer 2 is set and compacted, and then the interlocking bricks 6 in the shape of I can be laid. During the laying process, at the location of the beam grid frame 5, interlocking bricks 6 are first laid on both sides, and then the beam body is poured using the interlocking bricks 6 as templates. This ensures that the cast longitudinal beams 3 and transverse beams 4 are tightly connected with the interlocking bricks 6, enhancing strength and thus improving erosion resistance.

[0019] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
