[0002] As the main embedded parts of the joints of adjacent structures of water-passing structures in water conservancy projects, copper sheet water-stops have been increasingly widely used in the water-stopping system of hydraulic structures. However, in the past, people did not have a deep understanding of the functions of water-stop structures, and the quality control link in the construction process was not taken seriously, which resulted in the joints of adjacent structures of water-passing structures often becoming the main channel for water seepage, thereby reducing the normal function of the water-passing structures, service life, and safe operation of the structures. Moreover, copper sheet water-stop structures are often set at the joints of adjacent structures, making maintenance extremely difficult. If they are not repaired in time or the maintenance measures are inappropriate, it will inevitably endanger the lives and property of the people and cause immeasurable losses.

[0003] Based on the shortcomings and limitations of the existing copper sheet water-stopping structure during the construction process, this application aims to develop an inverted, integrally installed, reverse-worked copper sheet water-stopping fixing device that is economical and practical, has easy-to-guarantee water-stopping effects, is accurately installed, and can be widely promoted and applied.

[0018] As a further technical solution of the present invention, the asphalt adopts Grade A asphalt with a needle penetration greater than 100 mm, an elongation greater than 50 cm, and a softening point greater than 45°C.

[0019] As a further technical solution of the present invention, a copper sheet water stop elbow is fixedly installed on the side of the vertical copper sheet water stop away from the vertical asphalt well structure; copper sheet water stop pressure edges are fixedly installed on both ends of the horizontal copper sheet water stop, and the vertical copper sheet water stop is connected to the horizontal copper sheet water stop through a welding connection section.

[0020] As a further technical solution of the present invention, the length of the vertical copper sheet water stop inserted into the asphalt and the length buried in the concrete structure of the post-casting section are both 80 mm, and the copper sheet water stop elbow buried in the concrete structure of the post-casting section is bent 90 degrees toward the water-facing surface of the structure, and the bending length is 20 mm; the vertical copper sheet water stop is set at a distance of not less than 150 mm from the water-facing surface of the structure; the welded connection section is buried in the horizontal and vertical connection node structures.

[0026] The reverse copper sheet water-stopping fixing device is installed as a whole during construction;

[0027] The first step of construction is to pour the concrete structure;

[0028] Post-construction concrete structure.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The overall prefabrication and overall installation process is adopted to completely solve the problems of inaccurate installation positioning of copper sheet water-stopping and leakage caused by loose asphalt well injection at one time, and ensure the vertical water-stopping effect of the expansion joint of the water-passing structure;

[0031] 2. The horizontal pouring and inverted insertion method is adopted to overcome the limitation of installing copper sheet water stop before pouring asphalt well construction.

[0032] 3. When the asphalt pouring water-stopping inverted plugging construction is carried out, the site occupied is small, and the requirements for the site foundation surface conditions are not high. The site layout is relatively flexible, and the construction can be organized on the nearest working surface as needed, which reduces the restrictions on working conditions;

[0033] 4. It is exactly the opposite of the traditional asphalt well production method, that is, the vertical water-stop asphalt well is first installed in the structure, and the anchoring side is reserved outside the structure, which avoids the deformation and peeling of the vertical water-stop due to the influence of temperature after the asphalt well is poured and formed, and also reduces the exposure time of the poured asphalt well outside;

[0034] 5. The horizontal pouring and inverted insertion construction technology can be used to control the liquid level change process and the pouring speed during asphalt pouring in real time, making it easier to ensure the pouring quality. At the same time, it can prevent the asphalt liquid from overflowing during vertical pouring of asphalt wells and causing unnecessary pollution to the installation formwork or steel bar surface;

[0035] 6. The total weight of the asphalt well made by the horizontal pouring and inverted insertion method is only 20kg, which is convenient for transportation, installation and fixing, simple to operate and easy to construct;

[0036] 7. The factory-processed and customized copper sheet waterstop has good integrity, and the welding parts can be directly tested for penetration before leaving the factory, which reduces the difficulty of on-site welding and is not restricted by on-site working conditions. It saves materials and makes it easier to ensure the quality of joints. At the same time, it also avoids the blind spot problem of on-site welding seam detection. BRIEF DESCRIPTION OF THE DRAWINGS
