Benefits of technology

This patented technology provides an improved way to protect sea shores from corrosion caused by wave or tide movements during use. It allows it to stay longer without being damaged due to its ability to absorb water vapor while still maintaining good stability when installed properly. Additionally, this new type of material used instead of existing methods reduces costs compared with traditional ways that require maintenance once they are gone through. Overall, these improvements make better marine structures more durably resist against environmental factors like saltwater intrusion.

Problems solved by technology

This technical problem addressed in this patented text relates to how damaging corrosion can occur when constructing temporary waterproof buildings that provide shelter for sensitive areas like shorelines during winter months with high temperatures and strong wave activity. These building constructions often include heavy blocks made from stone material but they may remain permanently installed at their original location after being removed once needed.

Embodiment 1

[0025] Such as figure 1 , 2 As shown in . and 3, a movable permeable spur dam structure for protecting the coast from erosion includes a coast 1, caissons 2 and anchoring devices 3. The side of the coast 1 is provided with several rows of interlaced caissons 2, and adjacent caissons 2 Connected by the anchor chain 4, the center of the caisson 2 is hollowed out, and the upper end is provided with an opening, the two sides of the caisson 2 are symmetrically provided with connecting rings 5, the upper part of the caisson 2 is provided with a water inlet hole, and the bottom of the caisson 2 is provided with a trapezoidal sinking pad 6. The trapezoidal sinking pad 6 is placed on the coastal foundation 7. Anchoring devices 3 are provided on both sides of the caisson 2. The anchoring devices 3 are connected to the caisson 2 through a number of anchor chains 4 and fixed on the coastal foundation 7.

[0026] The spacing of caissons 2 decreases successively from the dam pillow to the ...

Embodiment 2

[0039] When the coast 1 will be eroded by seawater, it is necessary to establish a movable permeable spur group on the coast 1 to protect the coast from erosion, and transport the prefabricated reinforced concrete caisson 2 to the project sea area by barge 2. The seabed topography of the delivery location is leveled, and the leveled area is greater than the base area of ​​the caissons 2. According to the spacing of the caissons 2 is 5m, and the spacing of each row of caissons 2 is 2-3 times of the total length of a row of caissons 2. The trapezoidal sinking pad 6 and the anchoring device 3 are fixed by piling at a distance, and then the caisson 2 is put into the water. There is a water inlet hole on the caisson 2, and seawater enters the caisson 2 through the water inlet hole. Relying on the relationship between buoyancy and gravity, The caisson 2 sinks into the sea slowly, the water inlet hole increases the ballast of the caisson 2, and keeps the caisson 2 stable on the bottom...

Abstract

The invention provides a movable type permeable spur structure capable of preventing coast erosion. The movable type permeable spur structure capable of preventing coast erosion comprises a coast, open occasions and anchorage devices. A plurality rows of open occasions are installed on one side of the coast at intervals and in a staggered mode, and the adjacent open occasions are connected through anchorage devices; the center of each open occasion is in a hollow shape, an opening is formed in the upper end of each open occasion, connecting rings are symmetrically installed on the two sides of each open occasion, a water inlet hole is formed in each open occasion, a trapezoidal bottom mat is installed at the bottom of each open occasion, and trapezoidal bottom mats are arranged on the foundation of the coast; the anchorage devices are installed on the two sides of the open occasions and connected with the open occasions through a plurality of anchor chains so as to be fixed to the foundation of the coast. According to the movable type permeable spur structure capable of preventing coast erosion and a construction method, the effect of coast erosion prevention can be achieved, and the movable type permeable spur structure can be conveniently dismounted after the protection requirement is met; the permeable structure of a spur can reduce damage of waves and tides to the spur, so that the project amount is relatively reduced, and construction efficiency is improved; and in addition, construction materials of the dismounted spur can be recycled, and waste of construction materials is avoided.
