Construction method of water permeable cement pavement
A construction method of a water permeable cement pavement comprises the following steps: adding 2.5-5 parts of hectorite into 100-120 parts of water at normal temperature, uniformly stirring, standing for 20-30 hours, adding 300-500 parts of coarse aggregate, 100-120 parts of fine aggregate and 80-120 parts of cement, uniformly stirring, adding 6-10 parts of mica powder, and stirring for 20-40 minutes to obtain water permeable concrete slurry; paving the water permeable concrete slurry on a roadbed, carrying out flat vibration, and after the concrete is initially set, covering a film, watering and maintaining. After the concrete is dried, communicated three-dimensional pores are formed in the surface of the concrete, water absorption and water seepage can be achieved, good water-retainingproperty is achieved, and ground dust raising can be inhibited; and the mica powder is beneficial to maintaining a good pore structure of concrete. When the water permeable cement pavement is constructed, one-time forming is achieved, repeated water spraying is not needed in the maintenance process, the strength is high, the construction process is simple and convenient, and the construction period is shortened.
一种可透水的水泥路面的施工方法，常温下将2.5‑5份锂皂石加入到100~120份水中，搅拌均匀后静置20‑30h，然后加入粗骨料300‑500份、细骨料100‑120份和水泥80‑120份，搅拌均匀后，加入云母粉6‑10份，搅拌20‑40min，得透水混凝土浆体；将透水混凝土浆体摊铺到路基上，并进行平振，混凝土初凝后，覆膜浇水养护。本发明混凝土干燥后在混凝土表面形成连通的三维孔隙，能够吸水、渗水，且具有良好的保水性，有利于抑制地面扬尘；云母粉有利于保持混凝土良好的孔结构。本发明在可透水的水泥路面施工时，一次成型，养护过程不需要反复喷水，且强度高，施工过程简单、方便，缩短工期。
