桥梁工程预制空心板施工中易出现的质量问题主要有以下几个方面:①预制空心板高度控制不严,影响桥梁整体标高。②预制空心板总长控制不严出现长短不一,有的两端端面不垂直、斜交角大小不一致,桥板安装时出现难度。③预埋件埋设位置有的不正确,有的甚至漏设。④预制空心板顶板横向或底板纵向出现裂纹。⑤板的下层钢筋保护层厚度不足,出现露筋现象。⑥底座平面不平整,使板两端安设支座的位置高
Bridge construction prefabricated hollow slab construction prone to quality problems are mainly the following aspects: ① Prefabricated hollow slab height control, affecting the overall elevation of the bridge. The total length of prefabricated hollow slab laxity control appears, and some end faces are not vertical, skew angle is inconsistent size, the difficulty of installing the bridge. ③ Embedded parts buried some incorrect location, some even missing set. ④ prefabricated hollow roof or vertical cracks in the bottom plate. ⑤ plate of the lower layer of protective layer thickness is insufficient, there tendons phenomenon. ⑥ base plane is not flat, so that the support plate at both ends of the high position
