[0002] A sponge city refers to a city that can adapt to environmental changes and respond to natural disasters like a sponge, with good "elasticity". It absorbs, stores, infiltrates and purifies water when it rains, and "releases" and utilizes the stored water when needed. The primary function of achieving this is the water absorption function of urban buildings, and this function is mainly achieved through permeable pavements. The existing permeable pavements mainly include two types: cast-in-place permeable concrete pavements and permeable brick paving pavements.

[0003] Cast-in-place permeable concrete pavement refers to the use of permeable concrete produced on-site or in a mixing station as the surface layer of the road, while permeable brick paved pavement refers to the use of permeable bricks for paving. Both use the continuous hole structure in permeable concrete or permeable bricks to improve the permeability of the paved pavement, and then combine it with a permeable road base to absorb rainwater on the road surface.

In addition, due to its internal pore structure, the strength of permeable concrete components cannot be enhanced by burying steel bars inside the permeable concrete. Therefore, permeable concrete materials are difficult to use to make large-area paving components. Summary of the invention

DETAILED DESCRIPTION

[0036] In order to better understand the above technical solution, Figure 1-10 And specific implementation methods are used to describe the above technical solutions in detail.

[0037] refer to Figures 1 to 7 The present application discloses an assembled high-strength water-permeable component, including a component body 1, the component body 1 includes a water-permeable portion 11, a performance portion 12, a first docking block 121, a reinforcing net 13, an edge protection portion 14, a second docking block 141 and a splicing bolt 15.

[0038] The permeable part 11 is an integrated component made of a permeable concrete mixture through a casting process. The permeable concrete mixture is made of cement, mineral admixtures, coarse aggregates, admixtures and water through appropriate mixing and curing processes. It is a material with high porosity and permeability. The permeability coefficient of the permeable concrete is not less than 0.5mm / s, and the compressive strength is not less than 20Mpa.

[0039] The performance part 12 and the edge protection part 14 are one-piece components made of ultra-high performance concrete mixture through a casting process. Ultra-high performance concrete mixture is prepared by cement, mineral admixtures, fine aggregates, fiber reinforcement materials, high-efficiency water reducers and water through appropriate mixing and curing processes. After hardening, it is a cement-based composite material with high strength, high durability and other properties. Ultra-high performance concrete mixtures must have suitable working performance, and their slump expansion should be controlled between 500-700mm to ensure that ultra-high performance concrete can properly penetrate into permeable concrete, so that the hardened ultra-high performance concrete is firmly combined with the permeable concrete, and the pores of the permeable concrete are not blocked to affect its permeability. The compressive strength of the ultra-high performance concrete hardener shall not be less than 120MPa, and the flexural strength shall not be less than 18MPa.

[0040] The mineral admixture is composed of one or more of silica fume, slag powder and fly ash. The fine aggregate is river sand or quartz sand with good grade configuration and the maximum particle size is not more than 5mm. The coarse aggregate is crushed stone, pebble or other mineral particles or recycled aggregate that can be used as aggregate with a particle size greater than 5mm, preferably single-graded crushed stone and pebble with a particle size of 5-10mm.

[0041] The template used to make the water-permeable portion 11 is defined as frame template 1, the template used to make the edge protection portion 14 is defined as frame template 2, and the template used to open the first docking groove 111 is defined as a core template.

[0042] The upper end surface of the water permeable part 11 is provided with a first docking groove 111 for installing the performance part 12. The shape of the performance part 12 depends on the shape of the first docking groove 111, and the shape of the first docking groove 111 can be adjusted according to the load-bearing requirements and decorative design requirements of the component body 1 to meet the load-bearing requirements and decorative design requirements of the component body 1. According to the design of the shape of the first docking groove 111, the pattern matching of the water permeable part 11 and the performance part 12 can be formed to realize the design of laying the decorative pattern of the component body 1. The shape of the first docking groove 111 is realized by setting a core mold in the frame mold 1. During the casting process, the core mold and the frame mold 1 are first assembled, and the water permeable part 11 with the first docking groove 111 is cast in the gap between the inner wall of the frame mold 1 and the outer wall of the core mold. Then the core mold is taken out, and the performance part 12 is cast in the position of the original core mold, that is, in the first docking groove 111, and finally an integrated component with the performance part 12 embedded in the water permeable part 11 is formed. The reinforcing net 13 includes a plurality of transverse reinforcing ribs 131 and a plurality of longitudinal reinforcing ribs 132. The transverse reinforcing ribs 131 and the longitudinal reinforcing ribs 132 are perpendicular to each other, and the cross-distributed transverse reinforcing ribs 131 and the longitudinal reinforcing ribs 132 are laid in the first docking groove 111 at the upper end of the water-permeable portion 11. Among them, both ends of the transverse reinforcing ribs 131 pass through the first docking groove 111 and are inserted into the inside of the water-permeable portion 11, and both ends of the longitudinal reinforcing ribs 132 also pass through the first docking groove 111 and are inserted into the inside of the water-permeable portion 11. According to the strength requirements of the performance part 12, before the performance part 12 and the water-permeable portion 11 are cast, the reinforcing net 13 is laid at the core mold inside the frame mold 1. Since the area of ​​the reinforcing net 13 is larger than the area of ​​the core mold, when the water-permeable portion 11 is cast, the edge of the reinforcing net 13 can be cast inside the water-permeable portion 11. Then the core mold is removed, and then the ultra-high performance concrete mixture is filled into the first docking groove 111, and the performance part 12 is cast, and then the other parts of the reinforcing net 13 are wrapped inside the performance part 12, and the strength of the performance part 12 is enhanced by the reinforcing net 13, and the water-permeable part 11 outside the performance part 12 is reinforced by the reinforcing net 13, so as to improve the tightness of the connection between the performance part 12 and the water-permeable part 11. The outer wall of the water-permeable part 11 is provided with a second docking groove 112 for installing the edge protection part 14, and the second docking block 141 is fixedly installed on the inner wall of the edge protection part 14, and the second docking block 141 and the edge protection part 14 are integrally formed by the casting process.

[0043] Among them, a splicing groove 142 is provided on the outer wall of the edge protection part 14, and a limiting groove 143 is provided on the outer wall of the edge protection part 14 and near the splicing groove 142, and the inner diameter of the limiting groove 143 is greater than the inner diameter of the splicing groove 142. The second docking groove 112 is realized by setting a template for setting the second docking groove 112 on the inner side of the frame mold 1 when casting the water-permeable part 11. After the water-permeable part 11 is cast, the frame mold 1 on the outer side of the water-permeable part 11 is removed to leave the second docking groove 112 on the outer wall of the water-permeable part 11. A frame mold 2 for casting the edge protection part 14 is set on the periphery of the water-permeable part 11, and then the edge protection part 14 is cast between the water-permeable part 11 and the inner wall of the frame mold 2, forming the edge protection part 14 on the outer side of the water-permeable part 11 and with the second docking block 141. After the edge protection part 14 is cast, it is embedded in the inside of the water-permeable part 11 through the second docking block 141. Similarly, the limiting groove 143 and the splicing groove 142 are opened by setting corresponding templates on the inner side of the frame mold 2. The outer diameter of the external splicing bolt 15 matches the inner diameter of the splicing groove 142, and one end of the splicing bolt 15 is inserted into the splicing groove 142 on the outer wall of the edge protection part 14. One end of the splicing bolt 15 is inserted into the edge protection part 14 of one component body 1, and the other end of the splicing bolt 15 is inserted into the edge protection part 14 of another component body 1. The two component bodies 1 are connected by the splicing bolt 15, and then multiple component bodies 1 are spliced.

[0044] In the process of making the component body 1, the permeable concrete mixture for casting the permeable part 11 and the ultra-high performance concrete mixture for the performance part 12 are first prepared, and the frame mold 1 for casting the permeable part 11 is assembled at the casting point, and the core mold for opening the first docking groove 111 is assembled inside the frame mold 1. After the core mold is assembled, the reinforcing mesh 13 is laid in the core mold. The permeable concrete mixture is filled in the gap between the frame mold 1 and the core mold, and the permeable part 11 is cast by the casting process. After the permeable part 11 is cast, the core mold is removed, and the frame mold 2 for casting the edge protection part 14 is assembled on the periphery of the permeable part 11, and then the ultra-high performance concrete mixture is filled in the original position of the core mold, and the performance part 12 is cast by the casting process, and the ultra-high performance concrete mixture is filled between the permeable part 11 and the frame mold 2, and the edge protection part 14 is cast. After the edge protection part 14 and the performance part 12 are cast, the frame mold 2 is removed. The production of the component body 1 is completed.

[0045] When laying the component main body 1, one end of the splicing bolt 15 is inserted into the splicing groove 142 on one of the component main bodies 1, and the component main body 1 is laid at the position where it needs to be laid. Then, another component main body 1 is placed next to the previous component main body 1, and the other end of the splicing bolt 15 is inserted into the splicing groove 142 on the other component main body 1. The two adjacent component main bodies 1 are connected by the splicing bolt 15. In the same way, multiple component main bodies 1 are spliced ​​to complete the laying of multiple component main bodies 1.

[0046] refer to Figures 6 to 10 The splicing bolt 15 includes a limiting ring 151, an inserting tube 152, an abutting tube 153, an abutting block 154, a displacement bolt 155, an inner tube 156 and an expansion rubber 157. The inserting tube 152 is inserted into the splicing groove 142 provided on the edge protection part 14. The limiting ring 151 is fixedly mounted on one end of the inserting tube 152, and the outer diameter of the limiting ring 151 is larger than the outer diameter of the inserting tube 152. A limiting groove 143 for the limiting ring 151 to be inserted is provided on the outer side wall of the edge protection part 14 and close to the splicing groove 142, and the inner diameter of the limiting groove 143 is larger than the inner diameter of the splicing groove 142. The abutting tube 153 is fixedly mounted on one end of the inserting tube 152 inserted into the splicing groove 142, and the abutting tube 153 is completely inserted into the splicing groove 142. The outer wall of the abutting tube 153 is provided with a plurality of through grooves evenly distributed along the circumference of the abutting tube 153, and the abutting block 154 is slidably installed in the through groove of the abutting tube 153, and the abutting block 154 slides in the through groove. The displacement bolt 155 is inserted into the abutting tube 153, and the displacement bolt 155 is displaced along the length direction of the abutting tube 153. The content tube 156 is inserted into the inside of the limiting ring 151, and the outer wall of the content tube 156 is provided with a plurality of limiting grooves 158 evenly distributed along the circumference of the content tube 156. The content tube 156 is slidably connected to the limiting ring 151 through the limiting grooves 158, and the limiting ring 151 slides on the outer wall of the content tube 156. The expansion rubber 157 is filled in the inside of the content tube 156. Two limiting rings 151 are slidably connected to the outer wall of the content tube 156. The two limiting rings 151 are symmetrically distributed about the content tube 156, and the two ends of the expansion rubber 157 are respectively fixedly connected to the two limiting rings 151 on both sides of the content tube 156. When the expansion rubber 157 absorbs water and expands, the two ends of the expansion rubber 157 are squeezed toward the displacement of the limiting rings 151, so that the two limiting rings 151 on the outer wall of the content tube 156 are synchronously displaced to both sides of the content tube 156.

[0047] When two adjacent component bodies 1 are being laid, the abutment tube 153 at one end of the splicing bolt 15 is first inserted into the splicing groove 142 on one of the component bodies 1. When the limiting ring 151 is embedded in the limiting groove 143, the displacement bolt 155 inside the abutment tube 153 is squeezed by the inner side wall of the edge protection part 14, and the displacement bolt 155 is displaced toward the inside of the abutment tube 153. The outer side wall of the displacement bolt 155 squeezes the abutment block 154, so that the abutment block 154 slides toward the outside of the abutment tube 153 in the through groove, and then the abutment block 154 is pressed against the inner side wall of the splicing groove 142 of the edge protection part 14, so as to realize the fixing operation of the splicing bolt 15 on one component body 1. Similarly, the abutment tube 153 at the other end of the splicing bolt 15 is inserted into the splicing groove 142 on the other component body 1 to complete the connection of the two adjacent component bodies 1.

[0048] Under normal conditions and low precipitation, the content tube 156 is located inside the limit ring 151, and the expansion rubber 157 inside the content tube 156 is in a dry state. The volume of the expansion rubber 157 is small, and the two limit rings 151 on the two component bodies 1 abut against each other, and the gap between the two component bodies 1 is small. When the precipitation is high, the accumulated water penetrates into the water-permeable part 11 of the component body 1, and part of the accumulated water flows along the joint seam of the adjacent component bodies 1 to the inside of the content tube 156. The expansion rubber 157 inside the content tube 156 absorbs water and expands. The volume of the expanded expansion rubber 157 increases. Due to the restriction of the content tube 156, the expansion rubber 157 will extend to the two ends of the content tube 156, thereby pushing the limit rings 151 on both sides of the content tube 156 to move to the two sides of the content tube 156, thereby expanding the joint seam of the two adjacent component bodies 1, and accelerating the discharge of the surface water on the component body 1. The expansion rubber 157 continues to lose water in a dry environment, and its volume gradually shrinks, thereby restoring the joints of the adjacent component bodies 1 to their original state, making it easier to absorb subsequent accumulated water.

The permeable portion 11 is made, the strengthening net 13 is placed in the core mold, the mixed permeable concrete mixture is filled into the gap between the frame mold and the core mold, and compacted using a flat vibrator, after the pouring and curing is completed, the core mold and the frame mold are removed;

[0053] S4. The performance part 12 is made by placing the frame mold 2 on the periphery of the permeable part 11, filling the ultra-high performance concrete into the first docking groove 111 left after removing the core mold, and smoothing it with a trowel. Before smoothing, a small vibrator can be used to vibrate it appropriately. After pouring, remove the mold after resting, and perform maintenance in accordance with the corresponding maintenance system;

[0054] S5. The edge protection part 14 is made by filling the ultra-high performance concrete into the gap between the outer wall of the permeable part 11 and the inner wall of the frame mold 2, and smoothing it with a trowel.

At the same time, the ultra-high performance concrete mixture is filled into the first docking groove 111, and a small vibrating rod is used to vibrate appropriately, and then it is smoothed with a trowel. After pouring and curing, the frame mold 2 is removed to complete the production of the performance part 12 and the edge protection part 14, and then the production of the component body 1 is completed.
