[0002] During the construction process, it is often necessary to reserve small construction holes to meet the subsequent construction conditions, such as holes for laying out wires, holes for concrete pump pipes, etc. These holes will be sealed after the subsequent construction is completed.
[0003] The reserved openings at the construction site are generally fixed on the formwork surface with processed formwork boxes by steel nails and wires. When pouring concrete, the formwork boxes are easily dislocated, cracked and leaked due to the lateral pressure transmitted by the vibrating rod, causing inconvenience to subsequent construction. In addition, the reserved openings are usually sealed by supporting the formwork with vertical poles, planting reinforcement in the holes and pouring concrete. This sealing method has slow working efficiency, low efficiency and is prone to cracking and water seepage in the floor slabs. It is difficult to meet the needs of engineering use. Therefore, further improvement is needed. Utility Model Content
