High-pier prestressed concrete continuous rigid frame bridge closure construction grout stopping system
The invention provides a high-pier prestressed concrete continuous rigid frame bridge closure construction grout stopping system, and belongs to the technical field of bridge closure construction, the high-pier prestressed concrete continuous rigid frame bridge closure construction grout stopping system comprises a base plate, vertical plates are installed on the front side and the rear side of the upper end face of the base plate in a sliding mode, and the high-pier prestressed concrete continuous rigid frame bridge closure construction grout stopping system further comprises piers; the fastening mechanisms are arranged on the left side wall and the right side wall of the base plate; the clamping mechanism is arranged in the inner cavity of the base plate; a sealing mechanism; the pressure storage box is fixedly mounted on the side wall of the vertical plate, and the pressure storage box is filled with mold oil; and a demolding mechanism. Through cooperation of the clamping mechanism, the sealing mechanism and the like, the base plate and the vertical plate can be firmly fixed to the side bottom face and the side wall of the bridge pier, concrete grout is prevented from flowing out of a gap between the vertical plate and the bridge pier during pouring, and through cooperation of the demolding mechanism and the like, demolding oil in the pressure storage box can be sprayed to the surfaces of the base plate and the vertical plate; and the adsorption force to the formwork during concrete forming is reduced, so that workers can conveniently dismantle the whole mold in the later period.
本发明提供了一种高墩预应力混凝土连续刚构桥合龙施工止浆系统，属于桥梁合龙施工技术领域，包括基板，所述基板的上端面前后两侧滑动安装有立板，还包括：桥墩；紧固机构，所述紧固机构设置在基板的左右侧壁上；夹紧机构，所述夹紧机构设置在基板的内腔；密封机构；蓄压盒，所述蓄压盒固定安装在立板的侧壁上，蓄压盒内填充有脱模油；脱模机构。该发明通过夹紧机构与密封机构等的配合，能够使基板与立板牢牢的固定在桥墩侧底面与侧壁上，避免了浇筑时混凝土浆液从立板与桥墩的缝隙处流出，通过脱模机构等的配合，能够使蓄压盒内脱模油喷洒在基板与立板的表面，减小了混凝土成型时对模板的吸附力，从而方便了后期工人对整个模具的拆除。
