Detailed Description

As shown in fig. 1, the wall structure includes an inner wall 5 and an outer thermal insulation wall 6, the outer thermal insulation wall 6 is attached to the outer side of the inner wall 5, a bolt hole 51 is formed in the inner wall 5, the reason for water leakage of the outer thermal insulation wall 6 is that the outer thermal insulation wall 6 is not tightly attached to the inner wall 5, a gap 7 exists, then water leaks into the gap 7 between the outer thermal insulation wall 6 and the inner wall 5 from the outer thermal insulation wall 6, and then leaks into a room from the gap between the filler in the bolt hole 51 and the inner wall 5.

The first embodiment is as follows:

as shown in fig. 1, the present embodiment describes a repair device for external wall insulation leakage, which includes a high-pressure grouting machine 1, a connection hose 2 and a needle-shaped injection pipe 3, wherein two ends of the connection hose 2 are respectively communicated with a grout outlet of the high-pressure grouting machine 1 and a feed inlet of the needle-shaped injection pipe 3.

Before the equipment is used for plugging the leakage points of the outer heat-insulating wall 6, the positions of the bolt holes 51 are found out according to indoor leakage positions, and then fillers in the bolt holes 51 are cleaned, so that the bolt holes 51 are ensured to be free of impurities and dust. Then, the needle-shaped injection pipe 3 is inserted into the bolt hole 51, the slurry outlet of the needle-shaped injection pipe 3 is close to the gap 7 between the outer heat preservation wall 6 and the inner wall 5 as much as possible, then the high-pressure grouting machine 1 is started, mortar is injected into the bolt hole 51 through the needle-shaped injection pipe 3, and the gap 7 is blocked through the mortar, so that the leakage-proof effect is achieved.

The advantages of the device of the embodiment are as follows:

1. the wall surface is operated from the indoor, construction is not needed from the outer side of the wall surface, operation tools such as a hanging basket and the like are not needed, the safety is higher, and the cost is lower;

2. the outer heat preservation wall 6 does not need to be dismantled, so that the cost can be saved;

3. the water leakage point is searched indoors, and the gap 7 between the outer heat-insulating wall 6 and the inner wall 5 can be found more accurately.

Example two:

because the gap 7 between the outer heat preservation wall 6 and the inner wall 5 is generally extended for a long time, and the area of the gap 7 is large or small, in order to more fully block the gap 7, under the condition, the pressure can be maintained for a period of time in the grouting process, so that the mortar can enter the gap 7 through more flowing under pressure, and the blocking effect is improved.

For this purpose, as shown in fig. 1, a plugging member 4 may be sleeved on the needle-like injection tube 3, the plugging member 4 is generally made of an elastic material, such as elastic rubber, and when the bolt hole 51 is to be filled with mortar, the plugging member 4 is inserted into the bolt hole 51 to plug the bolt hole 51, thereby providing a closed space for pressure maintaining.

On this basis, as shown in fig. 1, a gas permeable tube 41 may be provided on the block piece 4, the gas permeable tube 41 penetrating the block piece 4 in a direction parallel to the needle-like injection tube 3. At this time, before grouting, the plugging member 4 can be plugged into the bolt hole 51, and in the grouting process, air in the bolt hole 51 can be discharged from the vent pipe 41, so that smooth grouting is ensured, and in the pressure maintaining process, only the vent pipe 41 needs to be plugged.

In this embodiment, as shown in fig. 1, the vent pipe 41 is sealed by the filter member 42 disposed at the outer end of the vent pipe 41, as shown in fig. 3, the filter member 42 includes a filter pipe 421, a support net 422 is disposed in the filter pipe 421, and a filter net is laid on the support net 422. In the grouting process, air can smoothly flow out of the support net 422 and the filter screen, and after mortar enters the support net 422 and the filter screen, the mortar can be blocked by the filter screen, so that the resistance of the mortar flowing out of the filter screen is improved, and the pressure maintaining is realized. To further increase the resistance of the mortar flowing out of the filtering elements 42, the filtering tube 421 may be arranged in a serpentine shape, and a plurality of supporting nets 422 and filtering nets may be arranged in the filtering tube 421 to increase the pressure holding pressure of the grouting.
