Stepped drainage type sidewalk pavement structure utilizing modified cement concrete
A stepped drainage type sidewalk pavement structure utilizing modified cement concrete comprises a bottom water-resisting layer, a stepped water-resisting layer arranged on the upper surface of the bottom water-resisting layer in a combined mode, an inverted stepped water seepage layer matched with the stepped water-resisting layer, a drainage port connected with the water seepage layer and an outer drainage area communicated with the drainage port. The water-resisting layer, the water seepage layer and the bottom water-resisting layer all have the gradient smaller than 5%, and the inner sides are high, and the outer sides are low. Sewage and rainwater seeping into the pavement of the sidewalk flow towards the outer side of the sidewalk under the action of gravity by utilizing the water permeability difference between the water seepage layer and the water-resisting layer and the inclined stepped structure formed by the water seepage layer and the water-resisting layer; according to the invention, residual accumulated water on the surface and in the sidewalk can be removed, the lower pavement and the roadbed can be protected from water seepage erosion, pavement diseases caused by accumulated water are avoided, the service life of the sidewalk is prolonged, the preparation cost is low, the construction is simple and convenient, the pavement frost resistance is strong, and the walking comfort is high; the method is suitable for large-scale popularization in urban sidewalk construction.
一种利用改性水泥混凝土的阶梯式排水型人行道路面结构，包括底部隔水层、组合设于底部隔水层上表面的阶梯状隔水层和与之配合的倒阶梯状渗水层、与渗水层连接的排水口和与排水口连通的外侧排水区域，隔水层、渗水层、底部隔水层均具有小于5%的坡度，且内侧高外侧低。本发明利用渗水层和隔水层的透水性能差异以及两者组成的倾斜阶梯型结构使渗入人行道路面内部的污水和雨水在重力作用下向人行道外侧流动，能够在排除人行道路表面和内部的积水残留的同时保护下层路面和路基不受渗水侵蚀，避免因积水引发的路面病害，从而延长人行道的使用寿命，制备成本低廉，施工简便，路面抗冻性能强以及步行舒适度高，适合在城市人行道建设中大规模推广。
