在预制或现浇行车梁的施工过程中,常采用预埋套管,以安装行车梁滑行线支架的方法。在我们这个工地行车梁施工中,施工单位为图方便,将模板对拉螺栓放在安装滑行线支架的套管中,振动混凝土时,水泥浆进入套管,并将它灌实。由于套管中螺栓被水泥浆包裹住,施工完后又没有及时将它抽出,而且水泥浆硬化后具有一定强度,清孔工作十分困难,最后不得不另想安装方法。有没有办法避免这种情况出现呢?我想如果采取以下措施,
In the construction process of prefabricated or cast-in-situ carriage beams, pre-embedded casing is often used to install the girder gliding line bracket. In our site construction beam construction, the construction unit made it convenient for the construction to place the formwork pull bolts in the casing where the gliding line bracket was installed. When the concrete is shaken, the cement slurry enters the casing and it is filled. Since the bolts in the casing were covered with cement slurry, they were not drawn out in time after the construction was completed, and the cement slurry had a certain strength after hardening, and the cleaning work was very difficult. Finally, the installation method was indispensable. Is there any way to avoid this? I think if you take the following measures,
