Description

Technical Field

[0001] The present invention relates to the technical field of building construction, in particular to a waterproof structure of a connecting opening of an underground garage and a construction method thereof. Background Art

[0002] With the development and progress of society, the scale of residential communities is getting larger and larger, and the number of underground garages required is also gradually increasing. Therefore, construction will be carried out in batches, and connecting openings need to be set up between underground garages at different construction stages to connect them with each other.

[0003] The connection between the two batches of construction often resulted in loose waterproof closures. The previously constructed underground garage experienced leakage at this location due to a lack of overlap in the exterior wall waterproofing. Therefore, addressing this area became a key and difficult point in preventing leakage during construction. Summary of the Invention

[0004] The present invention aims to provide a waterproof structure and construction method for underground garage access openings, addressing the existing technical issues of leaks in previously constructed underground garages due to poor waterproofing when connecting access openings constructed in two batches. The preferred technical solutions among the various technical solutions provided by the present invention are described in detail below.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The present invention provides a waterproof structure for an underground garage communication opening, comprising a water stop member, a waterproof structure, and an outer protective structure sequentially arranged at the communication opening, wherein:

[0007] A protective structure is provided on the periphery of the water stop, and a leveling layer is provided on the outer side of the protective structure;

[0008] The waterproof structure is arranged on the outside of the leveling layer and the outer wall of the underground garage;

[0009] The outer protective structure is arranged on the outer side of the waterproof structure.

[0010] Preferably, the waterstop member is made of a waterstop steel plate, and the outer side of the waterstop steel plate is coated with cement slurry.

[0011] Preferably, the protective structure is a cement brick wall, and the cement brick wall is used to surround the water-stop steel plate at the connecting port.

[0012] Preferably, the cement brick wall is built by multiple cement bricks, and the thickness of the cement brick wall is 200 mm.

[0013] Preferably, the outer protective structure is made of 50 mm thick extruded polystyrene board.

[0014] Preferably, the leveling layer is made of 20 mm thick cement mortar.

[0015] A construction method for a waterproof structure of an underground garage connecting opening comprises the following steps:

[0016] S1: The waterstop steel plate is protected by applying cement slurry;

[0017] S2: Use cement bricks to build a 200mm thick brick wall around the waterstop steel plate;

[0018] S3: Brick walls and basement exterior walls are leveled with 20mm thick cement mortar;

[0019] S4: Lay a waterproof layer at the reserved connection opening (same as the underground exterior wall), and lay the waterproof layer along the curved wall at the water-stop steel plate to form a whole with the exterior walls on both sides of the connection opening;

[0020] S5: The connecting opening and underground exterior wall are protected by 50mm thick extruded polystyrene board;

[0021] S6: Backfill in layers with a ratio of 3:7 ash soil.

[0022] The present invention provides a waterproof structure for an underground garage connecting opening and a construction method thereof. The reserved connecting opening is surrounded by a water-stop steel plate at the connecting opening with cement bricks, mortar is applied to the outer side of the bricks for leveling, and then a waterproof membrane is laid to form an integral whole with the waterproofing of the outer wall of the underground garage to reduce the hidden danger of leakage at the connecting opening. The waterproof layer can be tightly combined during the later connection, avoiding the problem that the existing conventional underground garage has no waterproof layer at the reserved connecting opening and only constructs the root of the water-stop steel plate for waterproofing of the outer wall, which is prone to leakage at the connecting opening and the problem that the waterproof layer is not tightly overlapped during the later connection construction.

[0030] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0031] The present invention provides a waterproof structure for a connecting opening of an underground garage. This embodiment includes a water stop member, a waterproof structure and an outer protective structure which are sequentially arranged at the connecting opening.

[0032] in, Figure 1 This is a structural diagram of the underground garage connecting port structure after construction is completed in this embodiment. Figure 1 As shown, a water stop is provided at the communication port. In this embodiment, the water stop is a water stop steel plate 1 , and cement slurry is applied on the outside of the water stop steel plate 1 to protect the water stop steel plate 1 .

[0033] Figure 2 Schematic diagram of the structure of the protective structure of the underground garage connecting port in this embodiment after construction is completed. Figure 2 As shown, a protective structure is provided around the outer periphery of the waterstop steel plate 1. The protective structure is a cement brick wall 4. The cement brick wall 4 is used to surround the waterstop steel plate 1 at the connection port. The cement brick wall 4 is constructed of multiple cement bricks and has a thickness of 200 mm. During construction, a 200 mm thick brick wall is built around the waterstop steel plate using cement bricks to surround the waterstop steel plate 1 at the connection port.

[0034] Figure 3 : is a structural diagram of the completed leveling layer construction of the underground garage connecting port in this embodiment. Figure 3As shown, a leveling layer 5 is provided on the outside of the protective structure. The leveling layer 5 adopts 20 mm thick cement mortar. The cement brick wall 4 and the outer wall of the basement are both leveled with 20 mm thick cement mortar. By providing the leveling layer 5, a cushion is paved for laying the waterproof structure to ensure that the waterproof structure is not affected by various deformations. In this embodiment, a 20 mm thick cement mortar is used as the leveling layer 5. Anti-cracking limiters can be added to the cement mortar to improve the bonding strength, toughness and crack resistance of the leveling layer 5, thereby improving the quality of the leveling layer 5, so as to achieve a better waterproof effect after laying the waterproof structure 6.

[0035] Figure 4 Schematic diagram of the structure of the underground garage connecting port after the waterproof layer construction is completed in this embodiment. Figure 4 As shown, the waterproof structure 6 is arranged on the outside of the leveling layer 5 and the outer wall 2 of the underground garage. The waterproof structure 6 adopts waterproof membrane, and the reserved connecting port adopts cement brick wall 4 to surround the water-stop steel plate 1 at the connecting port. The outer side of the cement brick wall 4 is leveled with 20mm thick cement mortar, and then the waterproof membrane is laid and formed into a whole with the waterproofing of the outer wall 2 of the underground garage, reducing the hidden danger of leakage at the connecting port, and avoiding leakage by forming a whole with the waterproofing of the outer wall.

[0036] The outer protective structure is arranged on the outside of the waterproof structure 6. The outer protective structure adopts 50mm thick extruded polystyrene board to effectively protect the connecting port and the underground outer wall.

[0037] A construction method for a waterproof structure of an underground garage connection port, Figure 5 This is the elevation diagram of the underground garage connection structure. Figure 5 As shown, the construction includes the following steps:

[0038] S1: The waterstop steel plate is protected by applying cement slurry;

[0039] S2: Use cement bricks to build a 200mm thick brick wall around the waterstop steel plate;

[0040] S3: Brick walls and basement exterior walls are leveled with 20mm thick cement mortar;

[0041] S4: Lay a waterproof layer at the reserved connection opening (same as the underground exterior wall), and lay the waterproof layer along the curved wall at the water-stop steel plate to form a whole with the exterior walls on both sides of the connection opening;

[0042] S5: The connecting opening and underground exterior wall are protected by 50mm thick extruded polystyrene board;

[0043] S6: Backfill in layers with a ratio of 3:7 ash soil.

[0044] The beneficial effects of this embodiment are: the reserved connecting port is surrounded by the water-stop steel plate at the connecting port with cement bricks, the outside of the bricks is smeared with mortar for leveling, and then the waterproof membrane is laid and formed into a whole with the waterproofing of the outer wall of the underground garage to reduce the hidden danger of leakage at the connecting port. The waterproof layer can be tightly combined during the later connection, avoiding the existing conventional underground garage where the reserved connecting port is not waterproofed and the outer wall waterproofing is only constructed at the root of the water-stop steel plate, which is prone to leakage at the connecting port and the problem of loose overlap of the waterproof layer during the later connection construction.
