Description
Technical Field
The invention relates to a rapid diffusion permeable drainage pavement structure with network communication, in particular to a pavement structure which can effectively flow and diffuse rainwater to achieve the effects of comprehensively draining water and preventing water accumulation, can effectively fully supplement the rainwater to underground soil and has more practical effect characteristics in the aspect of integral implementation and use.
Background
Generally, the ground formed by paving floor tiles is not permeable, so that the roots of landscape forests on sidewalks cannot breathe at ordinary times, the forests are easy to wither in dry and early seasons, and the roots cannot be irrigated in heavy rain, so that rainwater cannot permeate into a soil layer below the floor tiles in rain, water disasters are caused by water accumulation on the ground, and the life and property safety of people is further influenced in serious cases.
Therefore, a manufacturer can firstly arrange a drainage pipeline on the ground, and after the floor tiles are laid, drain holes are arranged on the floor tiles corresponding to the drainage pipeline, so that rainwater can flow into the drainage pipeline from the drain holes arranged on the floor tiles in a centralized manner and then is guided out through the drainage pipeline when raining, and the situation of water accumulation on the ground can be prevented; however, the floor tile is damaged to form the drainage holes, which not only causes inconvenience in construction, but also has a very limited drainage effect, and the drainage holes still have the situations of insufficient drainage and water accumulation when the rainfall is large, and further damages the aesthetic property of the floor tile.
Therefore, the inventor proposes a taiwan patent entitled "water permeable pavement reinforcement device" which is issued as an invention No. I541408 of 2016, 7, 11, and mainly includes a base and an upper cover; wherein: the base, its outer fringe has the connecting frame body, there are locating flanges in the outer fringe of two adjacent sides of the connecting frame body, and the upper end of two adjacent sides of the corresponding locating flange of the connecting frame body arranges and offers multiple inlaying slots, and there are U-shaped locating slots in the outer fringe of two adjacent sides of the connecting frame body different from locating flange, and there are inlaying the fixed lamellar body in the protruding formation of the U-shaped locating slot lower edge corresponding to each inlaying slot, and there are supporting parts in the connecting frame body, make the connecting frame body link with supporting part with the connecting rib, there are multiple water-permeable holes on the upper end of the supporting part, there are water storage tanks in the middle of the supporting part concavely; the upper cover is arranged corresponding to the supporting part of the base so as to cover the supporting part, and the water storage tank corresponding to the supporting part of the upper cover extends upwards to be convexly provided with a water guide pipe.
However, although the above-mentioned "permeable pavement reinforcing apparatus" can achieve better drainage effect, and can reduce the expected effect of damaging the integrity and the aesthetic property of the whole floor tile when being installed, it is found in practical application that, after the bases are assembled and combined with each other, the bases are not communicated with each other, but are not in a mutual conduction state, so that when raining, the permeable pavement reinforcing apparatus has the function of shielding the area without raining, and cannot assist the area with raining to drain water, so that when raining for a long time or heavy rain, only partial area positions can drain water, the effect of draining water comprehensively cannot be achieved, and water accumulation still occurs, so that the rainwater cannot be fully supplemented to the underground soil, and the structure still has an improved space in the whole design.
In addition, taiwan patent of invention No. I220432 published on 8/1/2004, entitled "construction method of environmental permeable pavement" was also developed by the manufacturers, and includes the following steps: a. the unit frameworks are combined by the water permeable pipes and the connecting net, and a plurality of unit frameworks are connected with one another to form a large area; b. laying the unit framework on the roadbed soil and the broken stone grading layer; c. pouring concrete slurry on the unit framework to enable the concrete slurry to be coagulated into concrete plates; d. a bituminous asphalt macadam or other surfacing material that can be used as a pavement is pressed over the concrete slab. However, in practice, the "construction method for an environment-friendly permeable pavement" still finds that, because the permeable pipes are not communicated with each other, and are not in a mutual communication state, the effect of full drainage cannot be achieved when raining, and water accumulation and rainwater cannot be fully supplemented to underground soil still occur.
Also, there is developed a taiwan patent entitled "modular environmental permeable pavement structure" as published in 581122 of 21/3/2004, wherein a permeable pipe and a connecting net are combined into a unit structure, the unit structure is precast into a plate body by a solidification material, the solidification material is floated on the upper surface of the plate body to form a pavement layer, and the pavement block is made into a modular pavement block which is suitable for being laid in groups to form an environmental permeable and permeable pavement. However, in practice, the above-mentioned "modular environmental-friendly permeable pavement structure" still finds that the permeable pipes are not connected to each other, but not in a mutual conduction state, so that the effect of full drainage can not be achieved when raining, and water accumulation can still occur, so that rainwater can not be fully supplemented to the underground soil.
Therefore, the inventor, with the knowledge of many years of abundant design development and practical manufacturing in the related industry, provides a rapid diffusion water-permeable drainage pavement structure with network communication by researching and improving the existing structure and defects, and expects to achieve the purpose of better practical value.
