[0040] Oblique vertical positioning steel bar 3: This is a component that plays a key positioning and fixing role. It is connected by welding at one end with the additional steel bar 2 inside the hollow rubber cylinder 4 and at the other end with the structural steel bar 6, forming a triangular structure, thereby firmly fixing the embedded rubber waterstop 1 in the predetermined position.

[0044] In summary, the various structural components of the embedded rubber waterstop 1 device cooperate with each other to achieve effective water stopping and structural reinforcement functions.

[0045] Example 2

[0047] Fixing the embedded rubber waterstop 1 in the middle of the side formwork 8;

[0048] Fixing the embedded rubber waterstop 1 using a combined reinforcement method of structural steel bar 6, oblique vertical positioning steel bar 3 and additional steel bar 2, wherein the structural steel bar 6, oblique vertical positioning steel bar 3 and additional steel bar 2 are connected by welding to form a triangular structure, and the embedded rubber waterstop 1 is reinforced by the triangular structure.

[0049] The method for fixing the embedded rubber waterstop 1 using a combined reinforcement method of structural steel bar 6, oblique vertical positioning steel bar 3 and additional steel bar 2 includes fixing the additional steel bar using the hollow rubber cylinder 4 reserved at both ends of the embedded rubber waterstop 1, and making artificial openings on the hollow rubber cylinder 4 to connect the additional steel bar with one end of the oblique vertical positioning steel bar 3 by welding.

[0050] The combination reinforcing method of the structural steel bar 6, the oblique vertical positioning steel bar 3 and the additional steel bar 2 is used to fix the middle-buried rubber waterstop 1, and the other end of the oblique vertical positioning steel bar 3 is welded to the structural steel bar 6, which is fixed on one side of the side formwork 8 and arranged vertically to the side formwork 8.

[0053] As shown in Figures 1-3 , in the embodiment, the middle part of the waterstop is reinforced by the combination of the side formwork 8, the formwork reinforcing steel pipe 9 and the formwork reinforcing batten 10. The side formwork 8 is pushed up and down to the middle-buried rubber waterstop 1, and the formwork reinforcing batten 10 is placed on the upper and lower parts of the middle-buried rubber waterstop 1 to make it tightly fixed. By using this combination reinforcing method for the middle part of the middle-buried rubber waterstop 1, the horizontal and vertical displacement of the middle part of the middle-buried rubber waterstop 1 can be effectively avoided, and good reinforcing effect can be achieved.

[0054] As a further embodiment,

[0055] First, prepare the middle-buried rubber waterstop 1, the side formwork 8, the formwork reinforcing steel pipe 9, the additional steel bar 2, the oblique vertical positioning steel bar 3 and the structural steel bar 6 and other components.

Hollow rubber cylinders 4 are reserved at both ends of the middle-buried rubber waterstop 1, and additional steel bars 2 are arranged in the hollow rubber cylinders 4 respectively.

[0057] Then, artificial openings 7 are made on the hollow rubber cylinders 4 in an equal interval manner. Through these openings, one end of the oblique vertical positioning steel bar 3 is inserted and welded to the additional steel bar 2. The oblique vertical positioning steel bar 3 is connected by welding two positioning steel bars at a certain acute angle.

[0058] Then, the other end of the oblique vertical positioning steel bar 3 is welded to the structural steel bar 6 arranged perpendicularly to the side formwork 8. In this way, the oblique vertical positioning steel bar 3 and the additional steel bar 2 and the structural steel bar 6 form a stable triangular structure through the welded connection, thereby effectively fixing the embedded rubber waterstop 1 and preventing displacement or deformation of the embedded rubber waterstop 1 during construction.

[0059] On one side of the side formwork 8, a plurality of vertical formwork reinforcing steel pipes 9 are arranged, and formwork reinforcing timber 10 is arranged between the formwork reinforcing steel pipes 9 and the side formwork 8, so as to enhance the stability and bearing capacity of the side formwork 8 and ensure that the entire waterstop device can maintain a good working state during construction such as concrete pouring.

[0060] In actual construction, the spacing of the artificial openings 7 on the hollow rubber cylinder 4 can be flexibly adjusted according to the specific conditions and requirements of the site, so as to adapt to different construction conditions and requirements, thereby guaranteeing the performance and water-stopping effect of the embedded rubber waterstop 1 device.
