公路澆筑式防撞墻模具—澆筑式防撞墻模具—宏旭規格尺寸

公路澆筑式防撞墻模具施工時不利于掃除氣泡，所以對混凝士配曲線，可采用恰當添加水泥用量及進步率的方法來處理，正常情況可將砂率進步2～3但砂率不能太大，含砂量過多，會使混凝土中的氣泡難以上升逸出。公路澆筑式防撞墻模具、中心隔離帶模具澆筑防撞墻混凝土完畢6～8h后，即應掩蓋，并用水養護。拆模后，關于一些部分的缺陷應進行及時的修補。首先，將氣泡或麻面的部位用水洗刷潔凈，然后用與混凝土相同的砂漿將氣泡或麻面抹平，然后用塑料薄膜將該部位掩蓋，繼續對其養護，養護完畢后，該部分的色彩應與其他部位色彩相同。

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.
