透水砖的使用事项
我们都知道在户外广场、路边的人行走道这种公共区域，因为没有遮雨棚，为了避免路面积水造成不便，所以大多会选择铺设透水砖，以确保雨水可以及时渗入地下。那么对于透水砖的使用您知道怎么进行吗？
We all know that in public areas such as outdoor squares and pedestrian walkways on the roadside, due to the lack of rain shelters, in order to avoid inconvenience caused by water on the road surface, most people choose to lay permeable bricks to ensure that rainwater can seep into the ground in a timely manner. Do you know how to use permeable bricks?
1、路基处理。根据设计图纸的要求开挖地面，确定好开挖的深度以及长宽尺寸，同时将路基上的土方等杂物清理干净，并对路基表面进行填土夯实操作，压实系数好能够达到95%以上。
1. Roadbed treatment. According to the requirements of the design drawings, excavate the ground, determine the depth and length/width dimensions of the excavation, and clean the soil and other debris on the roadbed. Fill and compact the surface of the roadbed, and the compaction coefficient can reach over 95%.
2、铺设垫层。垫层、基层以及缓冲层的铺设都属于路基的填土分层夯实操作，采用粗细不均的材料来填充路基可以确保良好的透水性，其中垫层所选用的主要是已经熟化的石灰颗粒、粘土等，石灰颗粒的直径一般不可超过5毫米，而粘土颗粒好也不要大于15毫米。垫层的铺设厚度一般在120毫米左右。
2. Lay the cushion layer. The laying of the cushion layer, base layer, and buffer layer all belong to the layered compaction operation of the roadbed. The use of materials with uneven thickness to fill the roadbed can ensure good permeability. The cushion layer mainly uses hardened lime particles, clay, etc. The diameter of lime particles should generally not exceed 5mm, and the diameter of clay particles should not exceed 15mm. The laying thickness of the cushion layer is generally around 120 millimeters.
3、铺设基层。基层位于垫层之上，一般可直接选用碎石铺设，铺设厚度大约为250毫米左右，压实系数必须达到92%以上。
3. Lay the base layer. The base layer is located above the cushion layer, and can generally be directly laid with crushed stones. The laying thickness is about 250 millimeters, and the compaction coefficient must reach 92% or above.
4、缓冲层处理。基层之上便是缓冲层了，这层直接与透水砖相接，所以表面必须做好找平工作，因此也被称为找平层。缓冲层一般可直接选用中砂铺设，所选用的中砂好具有3—5毫米左右的级配，以达到更好的透水效果。缓冲层的铺设不需要太厚，厚度达到30毫米便可。
4. Buffer layer processing. Above the base layer is the buffer layer, which is directly connected to permeable bricks, so the surface must be well leveled, hence it is also known as the leveling layer. The buffer layer can generally be directly laid with medium sand, which has a grading of around 3-5 millimeters to achieve better water permeability. The laying of the buffer layer does not need to be too thick, and the thickness can reach 30 millimeters.
5、铺设透水砖。缓冲层做好了找平工作之后，便可在路面铺设透水砖了。可利用水泥浆来固定透水砖，然后使用橡胶锤轻轻敲打，增强稳固性。每块透水砖之间需要保留大约2毫米左右的缝隙，可让雨水及时渗入地下。另外，对于有特殊图案的路面，则需要严格按照图纸上所设计的图案铺装透水砖，避免铺装错误，影响美观。
5. Lay permeable bricks. After leveling the buffer layer, permeable bricks can be laid on the road surface. Cement slurry can be used to fix permeable bricks, and then gently tap with a rubber hammer to enhance stability. A gap of approximately 2 millimeters needs to be left between each permeable brick to allow rainwater to seep into the ground in a timely manner. In addition, for roads with special patterns, it is necessary to strictly follow the design patterns on the drawings to lay permeable bricks to avoid paving errors and affecting aesthetics.
6、填接缝砂。为了增强整个路面的耐久性与稳固性，在透水砖铺设好之后还需要在表面扫填接缝砂。接缝砂一般选择中细砂，将其均匀的扫填在透水砖路面上，利用车轮进行碾压，也可直接让行人进行踩踏，让接缝砂完全填入缝隙中。
6. Fill the joint sand. In order to enhance the durability and stability of the entire road surface, it is necessary to sweep and fill the joint sand on the surface after the permeable bricks are laid. Joint sand is generally selected as medium to fine sand, which is evenly swept and filled onto a permeable brick road surface. It can be rolled with wheels or directly stepped on by pedestrians to completely fill the gap with joint sand.
7、路面清理。后便是对路面的清理了，将多余的接缝砂清扫干净，也可对透水砖路面进行一定的保养，例如使用丙烯酸类制剂喷洒或者进行风格化处理，延长透水砖的使用寿命，同时做出仿古的效果来。
7. Road cleaning. Afterwards, the road surface is cleaned, and excess joint sand is cleaned. It is also possible to maintain the permeable brick road surface, such as spraying with acrylic acid agents or conducting stylized treatment, to extend the service life of the permeable brick and create an antique effect.
