Description

Technical Field

[0001] This utility model belongs to the field of underground continuous wall technology and relates to a waterproof device for joints of underground continuous walls. Background Technology

[0002] The basement diaphragm wall is a fundamental engineering project. It involves using grab bucket or rotary trenching machinery on the ground to excavate a deep trench along the perimeter of the deep excavation project under mud slurry protection conditions. After forming a unit trench segment, a steel cage prefabricated on the ground is placed in the trench, and then concrete is poured using the tremie method to complete one unit wall segment. This process is repeated segment by segment to build a continuous reinforced concrete wall underground, which serves as a water-cutting, seepage-proof, load-bearing, and water-retaining structure.

[0003] Currently, the waterproofing layers on basement walls and floors may fail due to aging, cracking, or peeling, causing water to seep into the basement. Leaks can cause concrete to absorb water and expand, damaging structural stability and reducing load-bearing capacity. Long-term leaks can also cause calcium hydroxide inside the concrete to dissolve, leading to steel corrosion and accelerating alkali-aggregate reaction in the concrete, thus affecting structural safety. Utility Model Content

[0006] A waterproofing device for the joints of a continuous wall in a basement includes a right frame and a left frame. The right frame is provided with a lower horizontal plate 1, which is connected to an upper horizontal plate 1 via a vertical plate 1. A sealing plate 1 is provided on the top of the upper horizontal plate 1, and the sealing plate 1 is pressed and positioned by a pressure rod 1. The left frame is provided with a lower horizontal plate 2, which is connected to an upper horizontal plate 2 via a vertical plate 2. A sealing plate 2 is provided on the top of the upper horizontal plate 2, and the sealing plate 2 is pressed and positioned by a pressure rod 2. A steel cage is connected between the right frame and the left frame.

[0007] As a preferred embodiment of the present invention: the reinforcing cage is provided with a transverse threaded steel bar 1 and a transverse threaded steel bar 4. The transverse threaded steel bar 1 is connected to the transverse threaded steel bar 2 through the longitudinal threaded steel bar 1. The transverse threaded steel bar 4 is connected to the transverse threaded steel bar 3 through the longitudinal threaded steel bar 2. A diagonal brace is connected between the transverse threaded steel bar 2 and the transverse threaded steel bar 3.

[0008] As a preferred embodiment of this utility model: the diagonal support frame includes diagonal support frame one, diagonal support frame two, diagonal support frame three and diagonal support frame four.

[0012] The beneficial effects of this utility model are:

[0013] This utility model discloses a waterproofing device for the joints of a continuous basement wall. A steel cage connects the right and left frames, and a sealing plate is installed above both the right and left frames. The sealing plate is pressed and positioned by a pressure rod, keeping its position constant. Under the action of the sealing plate, water will not seep into the basement, and the joints of the continuous basement wall are impermeable, effectively preventing groundwater infiltration, ensuring the dryness and stability of the underground space, thereby preventing steel corrosion, ensuring the integrity and rigidity of the wall, enabling it to withstand greater pressure during foundation pit excavation, thus reducing the occurrence of foundation settlement or collapse accidents, and ensuring safety and reliability.
