在城市發(fā)展進(jìn)程中,隨著現(xiàn)代化建設(shè)的不斷推進(jìn),城市面臨著諸多生態(tài)環(huán)境問(wèn)題。傳統(tǒng)的硬質(zhì)鋪裝材料雖然為城市提供了堅(jiān)實(shí)的地面基礎(chǔ),但也帶來(lái)了一系列弊端,如雨水無(wú)法下滲,導(dǎo)致城市內(nèi)澇頻發(fā)、地下水位下降、熱島效應(yīng)加劇等。透水磚作為一種新型的環(huán)保建筑材料,憑借其獨(dú)特的透水性能和生態(tài)優(yōu)勢(shì),成為解決這些問(wèn)題的關(guān)鍵,為城市的可持續(xù)發(fā)展注入了新的活力。
In the process of urban development, with the continuous advancement of modernization construction, cities are facing many ecological and environmental problems. Although traditional hard pavement materials provide a solid ground foundation for cities, they also bring a series of drawbacks, such as the inability of rainwater to infiltrate, leading to frequent urban waterlogging, a decrease in groundwater level, and intensified heat island effect. Permeable bricks, as a new type of environmentally friendly building material, have become the key to solving these problems due to their unique permeability and ecological advantages, injecting new vitality into the sustainable development of cities.
一、透水磚的基本概念與類(lèi)型
1、 Basic concepts and types of permeable bricks
透水磚是一種具有良好透水性能的路面鋪裝材料,它通過(guò)特殊的生產(chǎn)工藝和配方設(shè)計(jì),使磚體內(nèi)部形成許多微小的孔隙,這些孔隙相互連通,從而讓雨水能夠迅速透過(guò)磚體,滲入地下。根據(jù)原材料和生產(chǎn)工藝的不同,透水磚主要分為以下幾種類(lèi)型:
Permeable bricks are a type of pavement material with good permeability. Through special production processes and formula design, many tiny pores are formed inside the brick body, which are interconnected, allowing rainwater to quickly penetrate the brick body and infiltrate underground. According to different raw materials and production processes, permeable bricks are mainly divided into the following types:
陶瓷透水磚:以廢棄的陶瓷碎片、工業(yè)尾礦等為主要原料,經(jīng)過(guò)粉碎、成型、高溫?zé)频裙に囍瞥伞_@種透水磚具有高強(qiáng)度、高耐磨性、耐候性好等優(yōu)點(diǎn),而且顏色豐富,裝飾性強(qiáng),常用于城市人行道、廣場(chǎng)等對(duì)美觀度要求較高的場(chǎng)所。
Ceramic permeable bricks: made mainly from discarded ceramic fragments, industrial tailings, etc., through processes such as crushing, forming, and high-temperature firing. This permeable brick has the advantages of high strength, high wear resistance, good weather resistance, and rich colors. It has strong decorative properties and is commonly used in places with high aesthetic requirements such as urban sidewalks and squares.
水泥透水磚:以水泥、骨料(如石英砂、碎石等)、添加劑等為主要原料,經(jīng)攪拌、成型、養(yǎng)護(hù)等工藝制成。水泥透水磚生產(chǎn)工藝相對(duì)簡(jiǎn)單,成本較低,透水性能較好,廣泛應(yīng)用于城市道路、停車(chē)場(chǎng)等場(chǎng)所。
Cement permeable brick: made mainly from cement, aggregates (such as quartz sand, crushed stone, etc.), additives, etc., through processes such as mixing, forming, and curing. The production process of cement permeable bricks is relatively simple, with low cost and good permeability, and is widely used in urban roads, parking lots, and other places.
再生骨料透水磚:利用建筑垃圾、廢棄混凝土等再生骨料作為主要原料,經(jīng)過(guò)加工處理后制成透水磚。這種透水磚不僅具有良好的透水性能,還能有效實(shí)現(xiàn)建筑垃圾的資源化利用,減少對(duì)天然資源的開(kāi)采,符合綠色環(huán)保的發(fā)展理念。
Recycled aggregate permeable brick: using recycled aggregates such as construction waste and waste concrete as the main raw materials, and processing them to make permeable bricks. This permeable brick not only has good permeability, but also effectively realizes the resource utilization of construction waste, reduces the exploitation of natural resources, and conforms to the development concept of green environmental protection.
二、透水磚的工作原理與性能特點(diǎn)
2、 The working principle and performance characteristics of permeable bricks
(一)工作原理
(1) Working principle
透水磚的透水原理主要基于其內(nèi)部的孔隙結(jié)構(gòu)。當(dāng)雨水落在透水磚表面時(shí),由于磚體內(nèi)部存在大量相互連通的孔隙,雨水在重力作用下,通過(guò)這些孔隙迅速滲透到磚體內(nèi)部,并進(jìn)一步下滲到地下土壤中。同時(shí),透水磚的孔隙結(jié)構(gòu)還能起到過(guò)濾和吸附作用,對(duì)雨水中的雜質(zhì)和污染物進(jìn)行一定程度的凈化,減少對(duì)地下水的污染。
The permeability principle of permeable bricks is mainly based on their internal pore structure. When rainwater falls on the surface of permeable bricks, due to the large number of interconnected pores inside the bricks, rainwater quickly penetrates into the interior of the bricks through these pores under the action of gravity and further infiltrates into the underground soil. At the same time, the pore structure of permeable bricks can also play a filtering and adsorption role, purifying impurities and pollutants in rainwater to a certain extent and reducing pollution to groundwater.
(二)性能特點(diǎn)
(2) Performance characteristics
透水性能優(yōu)異:透水磚的透水系數(shù)通常在 0.5 - 2.0mm/s 之間,遠(yuǎn)遠(yuǎn)高于傳統(tǒng)的硬質(zhì)鋪裝材料。這意味著在降雨時(shí),透水磚能夠快速讓雨水下滲,有效減少地表徑流,降低城市內(nèi)澇的風(fēng)險(xiǎn)。
Excellent permeability: The permeability coefficient of permeable bricks is usually between 0.5-2.0mm/s, far higher than traditional hard paving materials. This means that during rainfall, permeable bricks can quickly allow rainwater to infiltrate, effectively reducing surface runoff and lowering the risk of urban waterlogging.
生態(tài)環(huán)保:透水磚的生產(chǎn)過(guò)程中可以利用大量的工業(yè)廢渣和建筑垃圾,減少了對(duì)天然資源的消耗,同時(shí)降低了廢棄物對(duì)環(huán)境的污染。此外,透水磚能夠使雨水自然下滲,補(bǔ)充地下水,改善城市生態(tài)環(huán)境,緩解城市熱島效應(yīng)。
Ecological and environmental protection: The production process of permeable bricks can utilize a large amount of industrial waste and construction waste, reducing the consumption of natural resources and reducing the pollution of waste to the environment. In addition, permeable bricks can allow rainwater to naturally infiltrate, supplement groundwater, improve urban ecological environment, and alleviate urban heat island effect.
防滑降噪:透水磚表面粗糙,具有良好的防滑性能,能夠提高行人在雨天行走的安全性。同時(shí),透水磚的孔隙結(jié)構(gòu)可以吸收車(chē)輛行駛時(shí)產(chǎn)生的噪音,降低城市噪音污染。
Anti slip and noise reduction: The permeable brick has a rough surface and good anti slip performance, which can improve the safety of pedestrians walking in rainy days. Meanwhile, the pore structure of permeable bricks can absorb the noise generated by vehicle driving and reduce urban noise pollution.
強(qiáng)度高、耐久性好:經(jīng)過(guò)特殊工藝處理的透水磚,具有較高的抗壓強(qiáng)度和抗折強(qiáng)度,能夠承受車(chē)輛的碾壓和行人的踩踏。而且,透水磚具有良好的耐候性和抗凍融性能,在不同的氣候條件下都能保持穩(wěn)定的性能,使用壽命較長(zhǎng)。
High strength and good durability: Permeable bricks treated with special processes have high compressive and flexural strength, and can withstand vehicle crushing and pedestrian trampling. Moreover, permeable bricks have good weather resistance and freeze-thaw resistance, and can maintain stable performance under different climatic conditions, with a long service life.
裝飾性強(qiáng):透水磚可以通過(guò)添加不同的顏料和采用不同的成型工藝,制成各種顏色和圖案的產(chǎn)品,滿足不同場(chǎng)所的裝飾需求,為城市增添美觀的色彩。
Highly decorative: Permeable bricks can be made into various colors and patterns of products by adding different pigments and using different molding processes, meeting the decoration needs of different places and adding beautiful colors to the city.
