透水磚應符合以下特點：透氣性好，能迅速吸收熱量和水分，降低城市排水壓力，表面小不均勻，吸收車輛噪聲，防止路面反射。只有滿足上述特點，透水磚才能發揮較大的作用。

Permeable bricks should meet the following characteristics: good breathability, able to quickly absorb heat and moisture, reduce urban drainage pressure, have a small uneven surface, absorb vehicle noise, and prevent road reflection. Only by meeting the above characteristics can permeable bricks play a significant role.

透水磚的透水原理主要是吸濕磚，然后從磚的孔排到地下，防止路面積水，降低城市排水壓力。實施海綿城市建設，需要大量透水磚作為路面鋪裝材料。綜合利用尾礦等固體廢物，結合透水磚生產，可實現廢物資源處理，解決海綿城市建設的主要材料來源。

The permeable principle of permeable bricks is mainly to absorb moisture in the bricks, and then discharge it underground from the holes of the bricks to prevent road surface water and reduce urban drainage pressure. The implementation of sponge city construction requires a large amount of permeable bricks as pavement materials. The comprehensive utilization of solid waste such as tailings, combined with the production of permeable bricks, can achieve waste resource treatment and solve the main material source for sponge city construction.

應用范圍：廣泛應用于大多數城市道路、人行道、停車場、公園等景觀道路，消除暴雨、洪澇災害，收集凈化雨水，交通便利，符合海綿城市建設的基本要求。人行道鋪設采用環保透水磚，不僅可以較大限度地利用空間，而且具有良好的透水性。由于環保透水磚種類繁多，顏色不同，可根據工程建設的實際需要，采用不同顏色、型號、圖案的環保透水磚。為了解決停車位的問題，經常使用特殊的綠化磚，不僅可以解決停車與綠化之間的矛盾，而且可以解決停車困難的問題。關于通道，考慮到路面平整和路面標志劃分，多采用材料均勻、抗壓強的環保透水磚。步行道，為了方便施工，更多地使用碎石環保透水磚。

Scope of application: It is widely used in most urban roads, sidewalks, parking lots, parks and other landscape roads to eliminate rainstorm and flood disasters, collect and purify rainwater, and has convenient transportation, meeting the basic requirements of sponge city construction. The sidewalk is paved with environmentally friendly permeable bricks, which not only maximizes the use of space but also has good permeability. Due to the wide variety and different colors of environmentally friendly permeable bricks, different colors, models, and patterns of environmentally friendly permeable bricks can be used according to the actual needs of engineering construction. To solve the problem of parking spaces, special green bricks are often used, which not only solves the contradiction between parking and greening, but also solves the problem of parking difficulties. Regarding the channel, considering the smoothness of the road surface and the division of road markings, environmentally friendly permeable bricks with uniform materials and strong compressive strength are often used. Pedestrian walkways, in order to facilitate construction, use more environmentally friendly permeable bricks made of crushed stones.

透水磚具有良好的透水性、透氣性和保水性，具有冷卻、降噪、調節氣候、改善空氣質量、地表水循環等多種功能。由于它的出現，它解決了許多問題。透水磚解決了道路區域因雨水而進水的問題，影響了人們的行走。

Permeable bricks have good permeability, breathability, and water retention, and have various functions such as cooling, noise reduction, climate regulation, improving air quality, and surface water circulation. Due to its emergence, it has solved many problems. Permeable bricks solve the problem of water ingress in road areas due to rainwater, which affects people's walking.

許多城市使用了大量的混凝土、瀝青和其他不透水材料，城市有大量的燃燒設備，使地面無法吸收熱量，熱量停滯在城市內部，形成熱島效應。

Many cities use a large amount of concrete, asphalt, and other impermeable materials. The city has a large number of combustion equipment, which makes the ground unable to absorb heat, causing heat to stagnate inside the city, forming a heat island effect.

大雨來臨時，排水溝、下水道、地面不完善，導致路面積水，容易造成城市道路嚴重積水，不能迅速將雨水滲入地下，形成城市內澇。雨水被排出，不能緩解地下水。即使下雨了，雨后的城市也無疑成了“蒸籠”。因此，城市需要加強排水系統的升級，不斷改善路況，讓水回到“源”。

When heavy rain comes, the drainage ditch, sewer, and ground are not perfect, resulting in water on the road surface, which can easily cause serious waterlogging on urban roads and prevent rainwater from quickly seeping into the ground, leading to urban waterlogging. Rainwater is discharged and cannot alleviate groundwater. Even if it rains, the city after the rain undoubtedly becomes a "steamer". Therefore, cities need to strengthen the upgrading of drainage systems, continuously improve road conditions, and return water to its source.

生態透水磚具有很高的保水特性，孔隙率達到25%。一塊300*300*55mm的磚在保水量的情況下，一般可以保水0.98公斤。下雨時，它吸收和保存水分。在陽光下，保留在磚和基層的水分可以蒸發吸熱，緩解熱島效應；它還可以給周圍的植物帶來水分。

Ecological permeable bricks have high water retention characteristics, with a porosity of up to 25%. A 300 * 300 * 55mm brick can generally hold 0.98 kilograms of water while maintaining water retention. When it rains, it absorbs and preserves moisture. Under sunlight, the moisture retained in the bricks and base layer can evaporate and absorb heat, alleviating the heat island effect; It can also bring water to the surrounding plants.
