Municipal sidewalk recycled aggregate anti-blocking pervious concrete pavement construction process
The invention discloses a municipal sidewalk recycled aggregate anti-clogging pervious concrete pavement construction technology. The technology specifically comprises the following steps that S1, formworks are erected, specifically, according to design requirements, the work of formwork erecting and regional formwork erecting is conducted in a separated mode; s2, stirring and transporting the recycled aggregate pervious concrete: putting the pretreated recycled aggregate and a liquid additive into a stirrer, stirring in advance, adding cement, a reinforcing material and a powder additive after the surface of the material is uniformly wetted, stirring for one minute, and properly adding water according to the workability of a mixture until the mixture meets the requirement; the invention relates to the technical field of road construction. According to the municipal sidewalk recycled aggregate anti-clogging pervious concrete pavement construction method, the upper surface layer is made of hard and dense strong pervious concrete, the lower surface layer is made of recycled aggregate pervious concrete, the pervious geotechnical cloth is laid on the recycled graded gravel, and the pervious geotechnical cloth has the effects of filtering flowing soil particles in water and preventing a bearing layer from being clogged; water flow can pass smoothly, and the service life is prolonged.
本发明公开了市政人行道再生骨料防堵塞透水混凝土路面施工工艺，具体包括以下步骤：S1、模板支设：按设计要求进行分隔支设模板及区域支设模板工作；S2、再生骨料透水混凝土搅拌、运输：将预处理后的再生骨料和液体助剂放在搅拌机里先行搅拌，待物料表面均湿润后再加入水泥、强化料和粉体助剂，搅拌一分钟后视拌合物的工作性适当加水，直到拌合物达到要求为止；本发明涉及道路施工技术领域。该市政人行道再生骨料防堵塞透水混凝土路面施工工法，通过上面层采用质地坚硬密实的强固透水混凝土，下面层采用再生骨料透水混凝土，透水土工布铺设在再生级配砂石上，透水土工布具有过滤水中流土颗粒，防止承载层堵塞，保障水流顺利通过，延长使用寿命。
