The invention discloses an anti-backflow well lid for road construction and an assembling method of the anti-backflow well lid. The anti-backflow well lid comprises a well lid base, a well lid body and a movable leakage assembly. The movable leakage assembly capable of sliding up and down is installed in a vertical guide rail in an extending shell of the anti-backflow well lid. When road accumulated water is dredged, accumulated water downwards enters a liquid accumulation tank shell in the movable leakage assembly through water seepage holes in a main cover plate and downwards compresses a limiting supporting plate under the action of gravity, meanwhile, the vertical position of drainage holes downwards moves to the position below a sealing sleeve layer, and the accumulated water is drained out of the drainage holes. When sewer sewage flows backwards, the sewage flows into an extending shell, the liquid accumulation tank shell moves upwards under the buoyancy action of an inner buoyancy plate and an outer buoyancy plate, the drainage holes and the sealing sleeve layer are horizontal, or the drainage holes are located in the upper side of the sealing sleeve layer, so that the sewage cannot enter from the drainage holes, backward flowing and backflow are effectively prevented, and dredging management of well lids in a road is facilitated.
本发明公开了一种道路施工用防倒灌回流的井盖及其装配方法，包括井盖底座、井盖主体和活动渗漏组件，其延伸外壳中的垂直导轨中安装可上下滑动的活动渗漏组件，当进行道路积水疏通时，积水通过主盖板内的渗水孔向下进入活动渗漏组件内的蓄积液槽外壳中，并由重力的作用向下压缩限位支撑板，同时排水孔的垂直位置向下移至密封套层的下方，而积水则从排水孔排出，而当下水道中的污水发生倒灌时，污水上涌至延伸外壳内，蓄积液槽外壳则在内浮力板和外浮力板的浮力作用下向上位移，使排水孔与密封套层水平或排水孔位于密封套层的上侧，从而使污水无法从排水孔进入，其有效防止了倒灌回流的发生，方便于道路中各处井盖的疏通管理。
