The invention discloses a municipal sponge type road pavement structure and a construction method of the pavement structure. The municipal sponge type road pavement structure sequentially comprises a water permeable brick layer, a leveling layer, a sand filter layer, geotechnical cloth, a water storage layer, a base layer and a main drainage pipeline from top to bottom. A drainage pipe of the water storage layer is connected with a main drainage pipeline pre-buried in the base layer; the sand filter layer is paved on the upper layer of the water storage layer, and the sand filter layer and the water storage layer are separated by geotechnical cloth; the leveling layer and the water permeable brick layer are sequentially paved on the upper layer of the sand filter layer; the water-absorbing fiber bundles are added into the sand filtering layer, so that the gathering and permeating speed of downward seeping water is accelerated, and the water collecting and draining efficiency is improved; the water storage layer is innovatively added, the water storage function can be achieved when the water volume is small, meanwhile, the siphon structure is arranged, when the water displacement is large, water stored in the water storage tank can be rapidly drained, and water accumulation is avoided.
一种市政用海绵型道路铺装结构以及铺装结构的施工方法，从上至下依次包括：透水砖层、找平层、砂滤层、土工布、贮水层、基层、主排水管道；贮水层的排水管与基层内预埋主排水管道连接；砂滤层铺装于贮水层上层，砂滤层和贮水层被土工布隔开；找平层和透水砖层依次铺装于砂滤层上层；在砂滤层加入了吸水纤维束，加速了下渗水的聚集和渗透速度，提高了集水和排水效率；创新性增加了贮水层，能够在水量较小时实现贮水功能，同时设置了虹吸结构，在排水量较大时，能够快速排出贮水箱内存水，避免出现积水。
