Benefits of technology

This patented technology allows for easy repairs of damaged areas along coastlines caused from sea level subsidence (SSS). It uses special materials made up mostly of iron powder mixed with plaster clay) called Magnetosite®, an alkaline earth metal salt used during manufacturing process. These materials are designed to be easily applied over various types of terrain while still maintain their effectiveness at protecting these structures against damage due to seawater immersion. They also have specific properties such as controllable thickness, ability to absorb moisture, and resistance to wear out quickly without losing its strength when exposed to harsh environments like those associated with SSA's. Overall, this new material makes it possible to create effective solutions to prevent deteriorating marine ecology.

Problems solved by technology

This patented technical solution describes how damaged areas found within recessed sea or coastal environments may be caused by seawater impact damage during maneuverings over these structures due to factors like turbulence flow, tidal movements, oceanic currents (sea), and weather conditions that cause degradative processes involving salts and other substances present along with saltwater aquifers. These issues affect both structural properties and durability of reparements used in harbors where they were previously installed.

Embodiment 1

[0029] Embodiment 1: as figure 1 and figure 2 Shown, a kind of underwater fissure repair method of coral sand dredging island reef revetment slope, comprises the following steps:

[0030] Step 1: Ultrasonic detection is performed on the position and shape of the crack 1 to determine the size and position of the crack 1. In this embodiment, the size of the crack 1 is narrow.

[0031] Step 2: Drilling a guide hole 2 on the inclined surface of the slope body, the lower end of the guide hole 2 communicates with the crack 1, and the guide hole 2 is provided with a magnetic slurry guiding device. The magnetic slurry guiding device includes a hose 5, and a multi-section electromagnet 6 is arranged on the outside of the hose 5. The electromagnet 6 is connected to the electromagnetic adjustment device through a wire. The electromagnetic adjustment device is a DC power supply device, which can realize periodic adjustment of the current, such as DLC7000C It can be realized by a DC sta...

Embodiment 2

[0035] Embodiment 2: different from the embodiment, such as image 3 and 5 Shown, a kind of underwater fissure repair method of coral sand dredging island reef revetment slope, comprises the following steps:

[0036] Step 1. Ultrasonic detection of the position and shape of the crack 1 is carried out to determine the size and position of the crack 1. In this embodiment, the crack 1 has penetrated the bagged concrete layer 16 of the revetment slope mold and exposed the bagged sand cofferdam 15. Crack 1 cavity is less than 3~5m³.

[0037] Step 2. Install the magnetic slurry guiding device. The magnetic slurry guiding device includes a hollow rod body 11. The front end of the hollow rod body 11 is provided with a threaded expansion head 12. The hollow rod body 11 is installed on the slope above the crack, and the lower end side wall of the hollow rod body 11 is provided with a material hole. , the self-expanding embedding material forms an embedded body 13 at the lower end of t...

Embodiment 3

[0042] Embodiment 3: as different from Embodiment 2 Figure 4 and 5 Shown, a kind of underwater fissure repair method of coral sand dredging island reef revetment slope, comprises the following steps:

[0043] Step 1. Ultrasonic detection of the position and shape of the crack 1 is carried out to determine the size and position of the crack 1. In this embodiment, the crack 1 has penetrated the bagged concrete layer 16 of the revetment slope mold and exposed the bagged sand cofferdam 15. Fissure 1 has a large cavity, larger than 3-5m³, and the filling volume of slurry is relatively large.

[0044] Step 2. Install the magnetic slurry guiding device. The magnetic slurry guiding device includes a hollow rod body 11. The front end of the hollow rod body 11 is provided with a threaded expansion head 12. The hollow rod body 11 is installed on the slope above the crack, and the lower end side wall of the hollow rod body 11 is provided with a material hole. , the self-expanding embed...
