新型路缘石的构思
新型路缘石的构思
Conception of a New Type of Curb Stone
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 stone is composed of upper and lower double-layer composite structure, the upper layer is ordinary concrete, and the lower layer is porous concrete, which makes the lower layer of curb stone have the function of seepage. At least in the outer layer of porous concrete, there are concave holes and culverts extending along the longitudinal direction of curb stone, making it have the function of water diversion.
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 roadside stone, which can prevent rainwater from pouring into the pavement structure and make the surface layer have strong structural strength. Porous concrete is used in the lower layer to form a permeable layer, so that water in the pavement structure can be discharged smoothly through the permeable layer (usually the same cross-section of the road, the water in the road is higher than on both sides, and the water in the pavement structure, Under the action of gravity, it flows to both sides and discharges into the porous concrete layer of the margin when it reaches the pavement side. There are concave notches in porous concrete layer on the back side of curb stone, which extend longitudinally with curb stone. The seepage drainage is directed to drain into the rainwater wells along the curb, so that the water inside the pavement structure is thoroughly discharged.
