An anchoring system suitable for clastic and silt sedimentary substrates

Abstract

The invention discloses an anchoring system suitable for debris and silt deposition substrates, comprising an anchor body, a steel cable, and a steel drill for driving the anchor body into the sea base, the steel cable is connected with the anchor body, and the anchor body It is in the shape of a truncated cone, and the end of the anchor body with a larger area is provided with a hole for matching with the steel braze. The anchor body is inserted into the sea base to a depth not less than 10 times its length, and the steel cable extends 10cm to 50cm from the sea base. Compared with traditional methods such as piling on the water surface, placing iron anchors, and placing large cement bases, the operation method of the present invention will only have a temporary mild impact on the coral reef ecosystem, and will not destroy the original coral community of the base, and will not damage the coral reef ecosystem. The area affects a large area and changes the three-dimensional structure of the base, and the post-removal operation is also very simple, just cut off the steel cables that expose the base. At the same time, the steel cable can be extended by the cable and tied with a marker at the end to provide an anchor position for the small sampan to temporarily stop broadcasting in the reef area, so as to avoid damage to the coral reef caused by ships anchoring.

Description

technical field [0001] The invention relates to an anchoring system suitable for clastic and silt sedimentary substrates. Background technique [0002] Among the beautiful and vast underwater gardens, the most beautiful and moving is the coral reef. The islands and reefs in the South China Sea, with reef-building corals as the main body, are an important guarantee for my country's maritime sovereignty and a treasure house of valuable marine biodiversity and biologically active substances. They have very important ecological value, economic value and national strategic security value. Due to the slow growth of reef-building corals and the slow natural recovery process of coral reefs, there is an international consensus that the management of coral reefs needs to change from passive protection to active recovery strategies. One of the restoration methods generally accepted internationally is the coral nursery, that is, to cultivate small coral fragments in floating nurseries,...

[0005] 2) The traditional anchor chain is used for fixing. When the anchor body is put in, it will cause physical damage to the coral in the area. During the use, the waves and currents will cause the linked anchor chain to move on the substrate and cause damage to the substrate;

[0007] Moreover, most anchoring devices are difficult to effectively remove in the later stage, which will inevitably leave obvious artificial traces on the reef and even permanently change the substratum structure of the area.
