UHPC inspection well cover and production process thereof
According to the UHPC inspection well lid and the production process thereof, iron sand is added into a UHPC concrete formula to replace part of traditional fine quartz sand, the strength and the compression resistance of the iron sand are both superior to those of the fine quartz sand, and therefore the overall strength and the compression resistance of the UHPC concrete are improved, and the performance is further enhanced through steel fibers; the UHPC concrete is poured into the inspection well cover outer shell to replace a traditional iron or plastic well cover, the cost can be reduced, the strength of the inspection well cover is guaranteed, production is more convenient, the inspection well cover can be directly poured, demolding is not needed, the iron content is small, and the risk of being stolen is reduced, a plurality of reinforcing ribs are arranged on the outer wall of the main shell, the overall strength of the main shell can be improved, and the service life of the inspection well cover is prolonged. And the reinforcing ribs extend into the filling cavity, and the first reinforcing mesh is directly welded to the reinforcing ribs, so that the integrity between the first reinforcing mesh and the main shell can be improved, and the strength is improved.
本发明公开了一种UHPC窨井盖及其生产工艺，本发明通过将UHPC混凝土配方中加入铁砂替代部分传统细石英砂，铁砂强度，抗压性能均优于细石英砂，从而提高UHPC混凝土的整体强度、抗压性能，钢纤维进一步增强性能，通过将窨井盖外壳体内灌注UHPC混凝土来替代传统的铁质或塑料制井盖，能够降低成本，且保证窨井盖的强度，生产更方便，直接浇筑即可，无需脱模，含铁量少，减小被盗风险，本申请中将主壳体外壁设置多个加强肋条，能够提高主壳体的整体强度，提高承重性能，通过将加强肋条延伸至填充腔体内，并将第一钢筋网直接焊接在加强肋条上，能够提高第一钢筋网与主壳体之间整体性，提高强度。
