1、根據(jù)不同場所的道路設(shè)計要求開挖路床,并將地基中的一些雜物清理干凈,然后夯實土壤。與此同時,確定好路床的縱橫寬度以及深度,以符合設(shè)計要求為標(biāo)準(zhǔn)。在開挖路床的過程中需要注意避開地下所埋設(shè)的管線。
1. Excavate the roadbed according to the road design requirements of different locations, clean up some debris in the foundation, and then compact the soil. At the same time, determine the longitudinal and transverse width and depth of the roadbed to meet the design requirements as the standard. During the excavation of the roadbed, attention should be paid to avoiding buried pipelines underground.
2、人行道旁路沿石是將同一平面內(nèi)多條不同的道路進行區(qū)分,一般路基周圍都需要鋪設(shè)。因此在鋪設(shè)透水磚之前,同樣需要在道路的周圍先鋪設(shè)好路沿石。
2. Sidewalk sidewalks and curbstones are used to distinguish multiple different roads within the same plane, and generally need to be laid around the roadbed. Therefore, before laying permeable bricks, it is also necessary to lay curbstones around the road.
3、人行道透水磚路面需要先在基層上鋪設(shè)墊層,墊層所起到的作用主要是增強路面的強度以及耐久性,材料的要求上必須要兼具透水性和蓄水性。一般常用的墊層材料有級配碎石或者無砂混凝土,如果選擇無砂混凝土作為墊層,則直徑應(yīng)保持在5—10毫米之間,直徑較大的顆粒所占比例不能超過35%,否則會對強度有所影響。
3. The permeable brick pavement for sidewalks needs to first lay a cushion layer on the base layer. The main function of the cushion layer is to enhance the strength and durability of the pavement, and the material requirements must combine permeability and water storage. The commonly used cushion materials include graded crushed stone or sand free concrete. If sand free concrete is chosen as the cushion, the diameter should be kept between 5-10 millimeters, and the proportion of larger particles should not exceed 35%, otherwise it will affect the strength.
4、在正式鋪裝人行道透水磚之前還需要做好基層找平工作,此時可使用水平儀進行精準(zhǔn)測量。戶外可直接使用中砂均勻的攤鋪,中砂不可太細(xì),好保持有0.3—5毫米左右的粒徑,鋪設(shè)厚度大約在30—40毫米之間。為了提高施工效率,可利用刮板來刮平表面。
4. Before officially laying permeable bricks for sidewalks, it is necessary to do a good job of leveling the base layer. At this time, a level can be used for accurate measurement. Outdoor use of medium sand can be used for even paving, and the medium sand should not be too fine to maintain a particle size of about 0.3-5 millimeters, with a laying thickness of approximately 30-40 millimeters. To improve construction efficiency, a scraper can be used to smooth the surface.
5、鋪設(shè)好人行道透水磚找平層之后就可以在面層鋪設(shè)透水磚了,鋪設(shè)時可從邊角處開始施工,由外向內(nèi)進行,人工鋪設(shè)和機械整體鋪裝都可以。為了確保面層透水磚鋪設(shè)整齊美觀,平整度更好,可先在鋪設(shè)床上拉出直線將鋪設(shè)圖案先勾勒出來,然后按照預(yù)設(shè)的圖案來鋪裝,利用橡膠錘輕輕敲擊透水磚,使其具備一定的埋深,同時也可以通過這種方法來調(diào)整表面的平整度。
5. After laying the permeable brick leveling layer on the pedestrian walkway, permeable bricks can be laid on the surface layer. Construction can start from the corners and proceed from the outside to the inside. Both manual laying and mechanical overall paving can be used. In order to ensure that the permeable bricks on the surface layer are laid neatly and aesthetically pleasing, and have better flatness, a straight line can be drawn out on the laying bed to outline the laying pattern first, and then laid according to the preset pattern. The permeable bricks can be gently tapped with a rubber hammer to have a certain burial depth, and the surface flatness can also be adjusted through this method.
6、當(dāng)透水磚面層的所有透水磚都鋪設(shè)完成之后,為了確保牢固度,還需要進行夯實工作。夯實路面時要注意壓力的大小,不同厚度的透水磚所使用的壓力不相同。
6. After all the permeable bricks on the surface layer of the permeable bricks are laid, it is necessary to carry out compaction work to ensure firmness. When compacting the road surface, attention should be paid to the magnitude of pressure, as the pressure used for permeable bricks of different thicknesses varies.
7、為了增強透水磚之間的連鎖與緊密度,可在鋪設(shè)完成之后的透水磚面層上再利用細(xì)砂填補接縫處。填補時將這些細(xì)砂仔細(xì)掃填到縫隙內(nèi)部直至沒有明顯的空洞處。
7. In order to enhance the interlocking and tightness between permeable bricks, fine sand can be used to fill the joints on the surface layer of permeable bricks after laying. When filling, carefully sweep and fill these fine sands into the gaps until there are no obvious voids.
8、為了讓細(xì)砂更好的填補到縫隙內(nèi),鋪設(shè)后的養(yǎng)護也需要格外注意。前期養(yǎng)護可使用緩流水柱慢慢清刷,并將路面上多余的細(xì)砂清掃干凈。前期養(yǎng)護一般為3天左右,后期不需要頻繁的進行清掃或者清刷了。
8. In order to better fill the gaps with fine sand, special attention should also be paid to the maintenance after laying. In the early stage of maintenance, a slow flowing water column can be used to slowly clean and clean the excess fine sand on the road surface. The initial maintenance usually takes about 3 days, and there is no need for frequent cleaning or brushing in the later stage.
