Detailed Description
The utility model will be further described with reference to the drawings and detailed description.
Referring to fig. 1 and 2, in the hole plugging structure for a concrete wall, a concrete interface treating agent 2 is laid on the inner wall of the hole, waterproof mortar 1 is filled on one side of the hole far away from the hole port, and a plugging plate 3 is fixedly arranged at the hole port. In order to ensure strength and control production costs, the closure plate 3 preferably employs a steel plate. Expansion cement 6 is filled between the waterproof mortar 1 and the plugging plate 3, and a rubber gasket 5 is arranged between the plugging plate 3 and the concrete wall 7. The concrete interface treating agent 2 has the excellent performances of water resistance, damp and heat resistance and freeze thawing resistance, and can obviously enhance the bonding force between new and old concrete and between the concrete and plastering mortar. Preferably, the waterproof mortar 1 is polymer cement mortar, which has good durability, impermeability and compactness, extremely high adhesion and extremely strong waterproof and anti-corrosion effects, and after the polymer cement mortar is hardened, the polymer in the mortar can effectively seal the communicated pores, so that the compactness and crack resistance of the waterproof mortar 1 are increased, and the impermeability and impact resistance of the waterproof mortar 1 are improved. The expansion cement 6 in the utility model adopts micro expansion cement, the volume of the micro expansion cement cannot shrink in the hardening process, and the micro expansion cement slightly expands, so that micro cracks caused by shrinkage can be avoided.
Specifically, the plugging plate 3 is fixed on the wall body through bolts 4. Preferably, the bolts 4 are expansion bolts. The expansion bolts play a role in fixing the plugging plate 3 and exerting pressure on the rubber gasket 5, so that the steel plate 3 compresses the expansion rubber gasket 5, and play a role in preventing water leakage. Specifically, the rubber gasket 5 is a water-swelling rubber gasket, and the water-swelling rubber gasket swells when meeting water, so that the waterproof effect is better achieved.
More specifically, the cylindrical rubber gasket which is arranged in the hole and is matched with the diameter of the hole is arranged at the hole port, and the cylindrical rubber gasket is adhered with the rubber gasket 5, so that the edge of the hole port is further protected, and the waterproof and seepage-proof effects are enhanced.
Specifically, the expansion cement 6 is filled in the range of 1/3 length of the hole from the port to the side far away from the port, and by the arrangement, the expansion cement 6 can better fit hole plugging, and microcracks caused by shrinkage after construction are reduced, so that the properties of impermeability, frost resistance, corrosion resistance and the like of the contrast-response concrete structure are improved.
Specifically, the expansive cement 6 is micro expansive cement. The micro-expansion cement is concrete with micro-expansion characteristic, which is formed by mixing micro-expansion cement and aggregate with water, and the self-volume deformation of the micro-expansion cement can compensate the shrinkage deformation caused by temperature change so as to control and regulate the internal stress and prevent the generation of temperature cracks.
