Cast-in-place wharf surface layer construction process
The cast-in-place wharf surface layer construction technology comprises the following steps that S1, a pavement layer is cleaned, specifically, the top face of a prefabricated panel is cleaned, loose concrete and other sundries are chiseled away, and the surface of the panel is repeatedly washed with water; s2, measuring and setting out; s3, reinforcing steel bar binding is conducted, specifically, the reinforcing steel bars are cut off when meeting holes and structural joints, bent hooks are arranged, protective layers are reserved, and reinforcing ribs are arranged at the holes according to design requirements; s4, concrete pouring is conducted, specifically, before concrete pouring is conducted, elevation control points need to be arranged, and then parting side formworks are conducted on a pouring section; if the elevation control points are not qualified, the elevation control points continue to be arranged until the elevation control points are qualified through supervision acceptance, and then concrete pouring can be conducted; s5, concrete curing; s6, joint cutting; and S7, acceptance check. According to the method, wearing layer concrete and a cast-in-place surface layer are poured together, and wharf and approach bridge surface layer concrete is mixed by an onshore mixing station and pumped and poured by a trailer pump; and peeling and falling of the wearing layer are prevented.
本发明公开了一种现浇码头面层施工工艺，包括以下步骤：S1：铺装层清理：对预制面板顶面进行清理，凿除松散混凝土及其它杂物，用水反复冲洗面板表面；S2：测量放样；S3：钢筋绑扎：钢筋遇孔洞、结构缝处应切断，设置弯勾，留保护层，并按设计要求在洞口设置加强筋；S4：混凝土浇筑：混凝土浇筑浇筑之前，需要进行高程控制点放设，然后在浇筑段分缝侧模；进行监理验收，验收不合格的话，继续进行高程控制点放设，直到监理验收合格，方可进行混凝土浇筑；S5：混凝土养护；S6：切缝；S7：验收。本发明，将磨耗层混凝土与现浇面层一起浇筑，码头及引桥面层混凝土由陆上搅拌站拌制，拖泵泵送浇筑；防止磨耗层起皮脱落。
