The construction of bulk concrete in ship lock projects often employs large templates.Inclined rods are often adopted for reinforcement during on-site construction,and foam agents or wrapping tapes are used for grouting control to ensure the stability of the templates and increase their safety.However,this traditional method often has the disadvantages of complicated working procedures,poor grouting control effect,and poor concrete surface appearance after demoulding.To solve these problems,we propose an elastic material grouting control pad based on the bulk concrete construction using large templates,supplemented with threaded rods at the end.The pad can effectively prevent concrete slurry leakage and reserve rod protection layer to avoid corrosion.The grouting control pad has been applied to on-site construction with sound results,which greatly improves the construction quality and efficiency,and the concrete surface appearance.Finally,the results can provide references for grouting control in similar bulk concrete construction projects.
