[0017] like Figure 1 and Figure 2As shown, A is the indoor position, and B is the outdoor position. The utility model provides a waterproof structure of the flexible joint bottom plate of the underground exterior wall rear connecting channel, including a casting block 1 for fixing on the lower part of the side of the first building bottom plate 10, a first water stop strip 8 for fixing between the first building bottom plate 10 and the casting block 1, a water stop material 3 for filling between the casting block 1 and the second building bottom plate 11 and between the first building bottom plate 10 and the second building bottom plate 11, a first blocking section 4 for blocking the water stop material 3 on the indoor side, a second blocking section 5 for blocking the water stop material 3 on the outdoor side, and a surface waterproof component fixed outside the first blocking section 4. The first building bottom plate 10 is the bottom plate of the old building, and the second building bottom plate 11 is the bottom plate of the new building. When constructing the casting block 1, a small section of the side of the first building bottom plate 10 is first roughened and rebar-planted, and a concrete interface agent 6 is applied, and a section of the casting block 1 is cast externally. The casting block 1 is rigidly connected to the side of the first building base plate 10, and further reduces the distance between the second building base plate 11, reduces the cross-sectional area of the water seepage path, and extends the water seepage path. It is flexibly connected to the second building base plate 11 through the second water stop 2, and forms a first flexible waterproof system. The blocking effect of the first blocking section 4 and the second blocking section 5 forms a second waterproof system, and the first water stop 14 forms a third waterproof system. The rigid connection between the old and new building structures is changed to a flexible connection, reducing damage caused by uneven settlement. The three-layer defense system ensures the quality of waterproofing. The internal and external defenses work together to achieve an obvious waterproof effect.
[0018] Preferably, the surface waterproof component includes a first waterstop 14 for sealing the opening position of the gap between the first building base plate 10 and the second building plate, and two fixing plates respectively fixing the two sides of the first waterstop 14. Specifically, a receiving groove for installing the surface waterproof component is opened at the top position of the first building base plate 10 and the second building plate, and the two side walls of the receiving groove are correspondingly attached with lower angle steels 12, and the other side of the lower angle steel 12 is attached to the bottom wall of the receiving groove, and a gap is separated between the two lower angle steels 12. The first waterstop 14 is laid on the lower angle steel 12 and blocks the gap, and the top cover of the lower angle steel 12 is provided with a cover plate 15. The first waterstop 14 is arranged perpendicular to the gap between the first building base plate 10 and the second building plate. Both sides of the first waterstop 14 extend and are laid on the lower angle steel 12. The fixing plate is the upper angle steel 13. One side of the upper angle steel 13 is attached to the first waterstop 14 and is anchored to the first building base plate 10 or the second building plate respectively through the bolt 16 passing through the lower angle steel 12. The bolt 16 is anchored in the concrete to form a bent anchor section to ensure that the first waterstop 14 is firmly fixed.
[0019] Preferably, a second waterstop 2 for blocking water seepage is pre-buried in the casting block 1 and the second building base plate 11. The second waterstop 2 is arranged perpendicular to the gap between the casting block 1 and the second building base plate 11, and one end of the second waterstop 2 is buried in the casting block 1, and the other end is buried in the second building base plate 11. In this embodiment, the second waterstop 2 is a rubber second waterstop 2.
[0020] Preferably, a second water stop strip 9 for blocking water seepage is provided between the water stop material and the first blocking section. The second water stop strip 9 can prevent further water seepage from the gap between the first building bottom plate 10 and the second building bottom plate 11, thereby blocking the water seepage path.
[0021] Preferably, a waterproof layer is provided on the side of the casting block 1 and the bottom surface of the second building floor 11. The waterproof layer 7 is a continuous whole, and gaps should be avoided. The waterproof layer 7 covers the entire outer wall position of the junction between the new and old buildings, so as to avoid leakage in other positions due to excessive water seepage surface.
[0022] Preferably, the water-stopping material 3 is a polystyrene foam board. Since it has good waterproof performance, it is filled in the weak position in the middle of the seepage path, which can achieve waterproofing while having the function of elastically connecting new and old buildings.
[0023] Preferably, the waterproof layer 7 is a waterproof roll material, and the waterproof roll material commonly used in the prior art can be used. The waterproof roll material is not only easy to construct, but also has a better waterproof effect.
[0024] Preferably, the first blocking section 4 and the second blocking section 5 are both polyurethane sealing pastes. The polyurethane sealing pastes should be sealed at both ends of the water-stopping material to completely block water seepage from entering the room.
[0025] The utility model realizes the connection and waterproofing of the new and old buildings by using flexible waterproof materials, and solves the technical problem in the prior art that the base plate leakage is easy to occur due to different settlement at the opening connection of the underground passage of the new and old buildings. The utility model can ensure that the new and old structures can be deformed freely at the connection port in the later stage, and cracks will not be generated due to uneven settlement, which will damage the waterproofing, and the waterproofing quality of the connection port after construction is guaranteed.
