地面冻胀控制
Control of ground frost heave
  在严寒地区,多种土木工程的应用都需要面对地面冻胀这一难题,此问题的发生会导致公路、铁路、机场跑道等高低不平,底下管道移位,甚至会令房屋的基础结构受损。适当放置京都顺发挤塑板在路面基层之下,可以令冰霜渗透、路基结冰的可能性降至最低,有效的控制地面冻胀。和传统解决方法相比,可大大减少所需换土填料工作,并保证路面、地下管道等设施的使用功能及延长使用寿命。
In chilly area, many civil engineering projects have to face the problem of ground frost heave, which can cause unevenness of highway, railway, airport runway and etc. as well as displacement of underground piping, even damage of building foundation construction. By properly placing Jingdushunfa plastic extruded board under the road surface base course, the possibility of icy water infiltration and roadbed freezing can be minimized, and accordingly ground frost heave can be effectively controlled. Compared with conventional method, this practice can significantly save work on earth replacement and filling, and ensure the use function and delayed service life of such facilities as road surface and underground piping.
