Road surface waterproof and drainage construction method
The invention discloses a pavement waterproof and drainage construction method which comprises the following steps: paving a cement and gravel block mixture on the top of a roadbed bottom layer to form a water body blocking layer; before the water body group fault is formed, the positioning steel frame is inserted and fixed on the water body blocking layer, after the water body group fault is formed, a plurality of drainage pipe fittings are laid on the water body group fault, asphalt macadam is laid, and a drainage permeable layer is formed; and sequentially paving the asphalt concrete layers with different granularities on the drainage permeable layer to form the pavement layer. According to the device, roadbed fine-grained soil is blocked below the drainage permeable layer through the drainage pipe fitting, the situation that the pipeline is blocked by the roadbed fine-grained soil is reduced, an intersection impact area is formed at the joint of the top blocking pipe and the impact pipe, the impact effect is generated, the flowing speed is higher, and the situation that water is frozen in the pipeline is reduced; the fine-grained soil is flushed out of the pipeline through high-speed impact, the bottom blocks low-speed flowing of water in the pipeline, the flowing speed of the fine-grained soil of the roadbed is reduced, accumulation of the fine-grained soil of the roadbed is avoided, and the smoothness of the pipeline is improved.
本发明公开了一种路面防排水施工方法，包括：在路基底层的顶部铺设水泥、碎石块混合物，以形成水体阻断层；在水体组断层成型前将定位钢架插置固定在水体阻断层上，成型后将若干排水管件铺装在水体组断层上，并铺设沥青碎石，形成排水渗透层；将不同粒度的沥青混凝土层依次铺设在排水渗透层上，形成路面层。本发明中，排水管件将路基细粒土阻拦在排水渗透层以下，减少路基细粒土阻塞管道的情况，顶部阻断管与冲击管连接处形成交汇冲击区，产生冲击作用使得流动速度更快，减少了水体在管道内冻结的情况，并采用高速冲击将细粒土冲出管道外，底部阻断管内水体低速流动，减缓了路基细粒土流动速度，避免路基细粒土堆积，提高了管道流畅度。
