Round grouting test device for synchronous grouting test

The invention discloses a circular grouting test device for a synchronous grouting test, and belongs to shield simulation equipment. The device comprises a base, an arc-shaped groove is formed in the base, meanwhile, a cylindrical box body matched with the arc-shaped groove is further arranged, and the box body can rotate freely; a local prototype is arranged in the cylindrical box body, the local prototype comprises an arc-shaped shield shell, a shield tail brush and a duct piece which are sequentially arranged, the two ends of the local prototype are detachably and fixedly arranged on the side wall of the box body, and the width of the local prototype is smaller than the height of the box body. The local prototype is adopted to simulate the synchronous grouting process, the simulation is more accurate, and the cost is relatively low. 本发明公开了一种用于同步注浆试验的圆形注浆试验装置，属于盾构模拟设备。该装置包括底座，所述底座上设有弧形槽，同时还设有与所述弧形槽相匹配的圆筒形箱体，所述箱体能够自由转动；所述圆筒形箱体内部设有局部原型，所述局部原型包括依次设置的弧形的盾壳、盾尾刷和管片，所述局部原型的两端可拆卸的固定设置于所述箱体侧壁，所述局部原型的宽度小于所述箱体的高度。其采用局
