桥梁防撞墙养护与拆模
Maintenance and demolition of bridge anti-collision wall
撞墙模板拆除时间根据气温实行动态调整，目前模板拆除时间控制在混凝土浇注完成后24小时左右，模板拆除时现场设专人指挥，防止拆模过程损坏混凝土边角。
The demolition time of the formwork is adjusted dynamically according to the temperature. At present, the demolition time of the formwork is controlled about 24 hours after the completion of concrete pouring. A special person is set up on the spot to direct the demolition of the formwork so as to prevent the damage of the concrete edge during the demolition process.
养护：防撞墙混凝土浇注完成后，采用塑料薄膜对混凝土顶面进行覆盖湿水养护，防止气温过高混凝土表面发生裂缝，模板拆除后，及时用土工布对防撞墙混凝土进行包裹，并洒水养护，养护时间不小于7d，为确保养护质量，桥面专门设置二道自来水管用于养护供水。
Maintenance: After the concrete pouring of the anti-collision wall is completed, plastic film is used to cover the top surface of the concrete with wet water to prevent cracks on the surface of the concrete due to excessive temperature. After the template is removed, the concrete of the anti-collision wall is wrapped with Geotextile in time and maintained by sprinkling water. The maintenance time is not less than 7 days. In order to ensure the maintenance quality, the bridge deck is specially equipped with two water pipes for maintenance. Water.
