Problems solved by technology

[0007] It can be seen from the above process that the traditional water-stop screw antirust process is very troublesome. 1. It is necessary to pick grooves on the retaining wall. On the one hand, picking grooves on the reinforced concrete wall is time-consuming and labor-intensive. On the other hand, Picking the groove will inevitably destroy the reinforced concrete wall, resulting in the reduction of the thickness of the reinforced concrete wall steel protection layer. If the reinforcement is accidentally cut, it will also affect the durability of the overall structure; 2. When cutting the water-stop screw at the bottom of the groove, it cannot be guaranteed The cut of the water-stop screw is flush with the bottom of the tank. On the one hand, the exposed part of the water-stop screw in the tank is increased, which increases the area of ​​anti-rust paint. However, when painting the anti-rust paint, due to temperature changes, it is easy to cause paint Pores appear in the completely painted anti-rust paint, and the larger the painted area, the greater the possibility of the above phenomenon. There are still gaps, and it is not easy to paint the anti-rust paint completely. In order to ensure the effect of the anti-rust paint, brushing it several times can ensure the effect of the brushing. 3. The amount of waterproof mortar used

Example Embodiment

[0030] Example 1:

[0031] The invention includes a process for preventing the water-stop screw from returning to rust, which specifically includes the following steps:

[0032] a. Cut the water-stop screw 3 on the inner side of the retaining wall, so that the tangent plane of the water-stop screw 3 is flush with the retaining wall structural surface 2, and at the same time, the tangential plane of the water screw and the retaining wall structural surface 2 are adjacent to the water screw tangent plane smooth surface;

[0033] b. Coating the adhesive 12 matched with the waterproofing membrane 11 on the tangential plane of the water-stop screw 3 and the retaining wall structure surface 2 adjacent to the water-stop screw, the adhesive 12 is a waterproof adhesive 12, and the gluing area is 10-20mm larger than the cut plane radius of the water-stop screw, paste the waterproof membrane 11 on the retaining wall structural surface 2 through the adhesive 12, and cover the cut plane o...

Example Embodiment

[0036] Example 2:

[0037] like figure 1 , 2 As shown in the figure, the present invention also includes a structure for preventing the water-stop screw from returning to rust, including a retaining wall structural surface 2, a water-stop screw and a waterproof coil 11. Flush, the waterproof membrane 11 is fixed on the retaining wall structure surface 2 by the adhesive 12, and the waterproof membrane 11 covers the tangential plane of the water-stop screw, and the waterproof membrane 11 is larger than the tangent plane of the water-stop screw The radius is 10-20 mm, and the outer surfaces of the waterproof membrane 11 are rough surfaces.

[0038]Due to the above method and structure, in the construction process, it is very convenient to first cut the water-stop screw, which can ensure that the tangent plane of the water-stop screw is completely flush with the retaining wall structural surface 2; and after the cutting is completed, the gluing process can be performed immediate...

Abstract

A technology and structure for preventing a water stop screw from re-rusting specifically comprises the following steps that a, the water stop screw on the inner side of a retaining wall is cut, so that the tangent plane of the water stop screw is flush with the structural plane of the retaining wall; b, adhesive matched with the waterproof coiled material is coated on the cut plane of the water stop screw and the retaining wall structural surface adjacent to the water stop screw, the waterproof coiled material is pasted on the retaining wall structural surface through the adhesive and covers the cut plane of the water stop screw, and the waterproof coiled material is pressed to discharge bubbles; and c, after the adhesive is completely dried, carrying out a subsequent process. The construction steps are clear and simple, the rust prevention quality is greatly improved while the rust prevention construction speed of the water stop screw is increased, the work amount of re-rust rectification of the retaining wall water stop screw can be greatly reduced, the follow-up maintenance cost is reduced, and good economic, construction period and quality benefits are achieved.

Description

technical field [0001] The invention relates to a process and structure for preventing rusting of a water-stop screw. Background technique [0002] Before the decoration of the indoor retaining wall, the specification requires the anti-rust treatment of the water-stop screw on the retaining wall. The specific steps of the existing traditional technology for the anti-rust treatment of the water-stop screw on the indoor side are as follows: [0003] 1. Carry out grooving on the inner side of the retaining wall and around the position of the water-stop screw, so that the surrounding of the water-stop screw is completely exposed. [0004] 2. Cut the water stop screw so that the cut of the water stop screw is flush with the bottom of the groove. [0005] 3. Apply the first coat of anti-rust paint to the exposed part of the water-stop screw, and apply the second coat of anti-rust paint after the first coat of anti-rust paint is dry. [0006] 4. Finally, seal the groove with wate...
