Description

Technical Field

[0001] This utility model relates to the field of cement pavement technology, specifically to a cast-in-place concrete pavement structure. Background Technology

[0002] In modern urban construction, cast-in-place concrete pavement is widely used in urban roads, squares, parking lots, and other infrastructure projects due to its excellent strength and durability. As people's requirements for ecological protection and road performance continue to increase, permeability has become an important consideration in pavement design.

[0003] However, the current permeable bricks are laid directly on the leveling layer and lack a dedicated and stable support structure. During long-term use, they are prone to loosening and damage, which seriously affects the overall smoothness and service life of the road surface.

[0004] Meanwhile, the drainage channel design between the permeable bricks and the concrete layer in the existing structure is unreasonable. After rainwater infiltrates, it is easy to stagnate in the leveling layer, which not only reduces the permeability efficiency but may also cause erosion of the concrete layer.

[0005] Therefore, a cast-in-place concrete pavement structure is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a cast-in-place concrete pavement structure that solves the problems of existing permeable brick paving lacking stable support and being prone to loosening and damage, as well as unreasonable drainage channels leading to rainwater retention and erosion of the concrete layer.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cast-in-place concrete pavement structure, comprising a soil base layer, a subbase layer, and a concrete layer, wherein a leveling layer is laid on the upper surface of the concrete layer, and permeable bricks are laid on the upper surface of the leveling layer; The concrete layer contains a steel mesh, the leveling layer contains a grid frame, the grid frame has reserved holes for water permeability, and the steel mesh is made of interwoven transverse and longitudinal steel bars.

[0008] Preferably, the cushion layer is made of sand and gravel material, and the cushion layer is used to support, level and initially filter the superstructure.

[0009] In the design, the subbase is made of sand and gravel, which effectively disperses the load of the superstructure, improves the smoothness of the road surface, and filters rainwater to prevent impurities from clogging the drainage channels in the lower layer.

[0010] Preferably, the concrete layer is made by concrete pouring and is used to support the main structure of the road surface.

[0011] In the design, the concrete layer is poured with concrete, which provides a high-strength and high-stability load-bearing foundation for the road surface, ensuring that the road surface can withstand long-term traffic loads.

[0012] Preferably, the permeable bricks are bonded to the leveling layer with cement mortar, which is used to fix the position of the permeable bricks and fill the gaps between the permeable bricks and the leveling layer.

[0013] In the design, the permeable bricks are bonded to the leveling layer with cement mortar, which achieves the advantages of firmly fixing the permeable bricks and preventing them from loosening and shifting, while filling the gaps to prevent water from seeping into the leveling layer.

[0014] Preferably, the transverse and longitudinal reinforcing bars of the steel mesh are interwoven, and the steel mesh is used to prevent cracks from forming in the concrete layer.

[0015] In the design, the steel mesh is made up of interwoven transverse and longitudinal steel bars, which achieves the advantages of enhancing the toughness and crack resistance of the concrete layer and extending the service life of the concrete layer.

[0016] Preferably, the grid frame is adapted to the permeable brick paving layout, and the grid frame is used to maintain the flatness of the permeable brick paving.

[0017] In the design, the grid frame adopts a design that adapts to the layout of permeable brick paving, which effectively maintains the flatness of the permeable brick paving and avoids affecting the performance of the road surface due to local depressions or protrusions.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model sets up a grid frame and embeds it into the leveling layer. Its structure is adapted to the permeable brick paving layout, forming a rigid support frame. This achieves the goal of restraining the displacement of permeable bricks, maintaining the flatness of the paving, and solving the problem that existing permeable bricks lack stable support and are prone to loosening and damage. Meanwhile, by opening pre-drilled holes in the grid frame to form a continuous drainage channel with the pores of the permeable bricks, rainwater is guided to quickly infiltrate below the concrete layer, thus avoiding stagnation and erosion within the leveling layer.

[0019] In addition, a steel mesh composed of interwoven transverse and longitudinal steel bars is set inside the concrete layer, which enhances the crack resistance of the concrete layer, indirectly provides stable base support for the permeable bricks, and further improves the durability of the pavement structure.

Meanwhile, by opening reserved holes 61 on the grid frame 6 to form a through drainage channel with the pores of the permeable brick 4, the rainwater is guided to quickly infiltrate below the concrete layer 3, thus avoiding stagnation and erosion in the leveling layer 5.

[0025] In addition, a steel mesh 7, composed of transverse steel bars 71 and longitudinal steel bars 72, is set inside the concrete layer 3, which enhances the crack resistance of the concrete layer 3, indirectly provides stable base support for the permeable bricks 4, and further improves the durability of the pavement structure.

[0026] Example 2 In order to achieve effective load-bearing capacity, leveling, and preliminary rainwater filtration for the superstructure, such as Figure 1 and Figure 2As shown in this embodiment, the cushion layer 2 is made of sand and gravel material. The cushion layer 2 is used to support, level and initially filter the upper structure.

[0027] Specifically, the subbase 2 is made of sand and gravel, which effectively disperses the load of the superstructure, improves the smoothness of the road surface, and initially filters rainwater to prevent impurities from clogging the drainage channels of the lower layer.

[0028] Furthermore, concrete layer 3 is constructed by pouring concrete and serves as the main structure supporting the road surface.

[0029] Specifically, concrete layer 3 is constructed by pouring concrete, which provides a high-strength and high-stability load-bearing foundation for the road surface, ensuring that the road surface can withstand long-term traffic loads.

[0030] Furthermore, the permeable brick 4 and the leveling layer 5 are bonded together with cement mortar. The cement mortar is used to fix the position of the permeable brick 4 and fill the gap between the permeable brick 4 and the leveling layer 5.

[0031] Specifically, the permeable brick 4 and the leveling layer 5 are bonded together with cement mortar, which achieves the advantages of firmly fixing the permeable brick 4, preventing it from loosening and shifting, and filling the gaps to prevent water from seeping into the leveling layer.

[0032] Example 3 To achieve crack resistance strengthening of concrete layer 3, such as Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the transverse reinforcing bars 71 and the longitudinal reinforcing bars 72 of the reinforcing mesh 7 are interwoven, and the reinforcing mesh 7 is used to prevent cracks from forming in the concrete layer 3.

[0033] Specifically, the steel mesh 7 is made of interwoven transverse steel bars 71 and longitudinal steel bars 72, which achieves the advantages of enhancing the toughness and crack resistance of the concrete layer 3 and extending the service life of the concrete layer 3.

[0034] Furthermore, the grid frame 6 is adapted to the paving layout of the permeable bricks 4, and the grid frame 6 is used to maintain the flatness of the permeable bricks 4 paving.

[0036] When using this utility model, the original soil base 1 is leveled and cleaned, and a road roller is used to compact it in layers to ensure that the compaction degree meets the design standard, so as to provide a stable foundation for the superstructure.

[0037] Sand and gravel material is laid on the soil base layer 1 as the subbase layer 2. The thickness is controlled by mechanical spreading or manual leveling, and the material is repeatedly rolled with a vibratory roller until it is dense, so as to achieve the functions of bearing the load of the superstructure, leveling and preliminary filtering of rainwater.

[0038] Transverse steel bars 71 and longitudinal steel bars 72 are arranged above the foundation layer 2 at the designed spacing. They are interwoven into a steel mesh 7 by binding or welding, covering the entire construction area of ​​the concrete layer 3 to enhance the crack resistance of the concrete.

[0039] A formwork is erected along the outside of the steel mesh 7, and ready-mixed concrete or on-site mixed concrete is used for pouring. The vibrator is used to vibrate the concrete evenly until the surface of the concrete is covered with slurry, ensuring that the steel mesh 7 is completely wrapped in the concrete layer 3. After the concrete has initially set, the grid frame 6 is embedded and the grid frame 6 is fixed by the leveling layer 5 slurry to maintain the flatness of the subsequent permeable brick 4 paving.

[0040] Before the leveling layer 5 sets, permeable bricks 4 are laid according to the layout reserved by the grid frame 6. A cement mortar bonding layer is applied between the bottom surface of the bricks and the leveling layer 5 to ensure that the flatness error of the paving does not exceed the design standard.

[0041] After the permeable bricks are laid, clean the debris from the brick surface, fill the gaps between the bricks with cement mortar, and spray water for curing after the adhesive layer has initially set to avoid the bricks loosening due to insufficient early strength.
