公路浇筑式防撞墙模具—浇筑式防撞墙模具—宏旭规格尺寸

公路浇筑式防撞墙模具施工时不利于扫除气泡，所以对混凝士配曲线，可采用恰当添加水泥用量及进步率的方法来处理，正常情況可将砂率进步2～3但砂率不能太大，含砂量过多，会使混凝土中的气泡难以上升逸出。公路浇筑式防撞墙模具、中心隔离带模具浇筑防撞墙混凝土完毕6～8h后，即应掩盖，并用水养护。拆模后，关于一些部分的缺陷应进行及时的修补。首先，将气泡或麻面的部位用水洗刷洁净，然后用与混凝土相同的砂浆将气泡或麻面抹平，然后用塑料薄膜将该部位掩盖，继续对其养护，养护完毕后，该部分的色彩应与其他部位色彩相同。

The mold construction of the highway pouring anti-collision wall is not conducive to the removal of bubbles, so the method of adding the amount of cement and the rate of progress can be used to deal with the curve of the concrete. Under normal circumstances, the sａnd rate can be improved by 2-3, but the sａnd rate cannot be too large, and the sａnd content is too much, which will make it difficult for the bubbles in the concrete to rise and escape. 6-8h after the completion of the pouring of the anti-collision wall mold and the center isolation belt mold, the anti-collision wall concrete shall be covered up and cured with water. After formwork removal, some defects shall be repaired in time. First, clean the bubble or pockmarked surface with water, then smooth the bubble or pockmarked surface with the same mortar as the concrete, then cover the part with plastic film, and continue to cure it. After curing, the color of this part shall be the same as that of other parts.
