新型路缘石的构思
新型路缘石的构思
Conception of new type curb
新型路缘石采用上下双层复合结构，上层为普通混凝土，下层为多孔混凝土，从而使得路缘石下层具有渗水功能；路缘石背面外侧至少在多孔混凝土层内有随路缘石纵向延伸的内凹缺口孔涵，使之具有引水功能。
The new type of curb adopts a double-layer composite structure, the upper layer is ordinary concrete, the lower layer is porous concrete, so that the lower layer of the curb has the function of water seepage; at least in the porous concrete layer on the back side of the curb, there is a concave notch culvert extending longitudinally with the curb to make it have the water diversion function.
路缘石上层采用普通混凝土，其不透水性可以避免路面雨水倒灌至路面结构内，同时使得面层具有较强的结构强度；下层采用多孔混凝土，形成透水层，可以使路面结构内的水通过该透水层得到顺畅外排（通常道路同一横断面，路中要高于两边，路面结构内部水，在重力作用下向两侧流动，到达路面边即进入缘石的多孔混凝土层排出）。路缘石背面外侧在多孔混凝土层内有随缘石纵向延伸的内凹缺口孔涵，将渗排水引导排入路边相间的雨水井，从而彻底排出路面结构内部水。
Ordinary concrete is used in the upper layer of the curb, which can prevent the rainwater from flowing back into the pavement structure and make the surface layer have strong structural strength; the porous concrete is used in the lower layer to form a permeable layer, which can make the water in the pavement structure drain smoothly through the permeable layer (generally, the water in the road structure is higher than both sides in the same cross section of the road, Under the action of gravity, it flows to both sides and reaches the pavement edge, which is discharged into the porous concrete layer of curb. In the porous concrete layer on the back side of the curb, there is a concave notch culvert extending longitudinally along with the curb, which will lead the seepage drainage into the rainwater wells alternately along the roadside, so as to completely discharge the internal water of the pavement structure.
