Embodiment 1

[0031] Such as figure 1 As shown, the connecting assembly can be a plastic expansion tube 10 and a stainless steel self-tapping screw 11, which can be used for fixing artificial algae reefs of small reef blocks, and the specific methods are as follows:

[0032] First pour the small cement reefs with stainless steel self-tapping screws, and then spray seaweed spores on the algal reefs of the small reefs. After the spores are attached, according to the needs of transplantation, the seaweeds can be fixed to the repair area after they grow to a certain size. Adopt SCUBA diving method, drill the hole of M8 on the natural rock reef of suitable depth with water pneumatic percussion drill, about 4 centimeters of hole depths, then nail into the plastic expansion pipe 10 in the hole, at last the band stainless steel self-tapping screw that has attached seedling The small reef block artificial algal reef 2 of 11 is screwed in the plastic expansion pipe 10 and is tightened. At this time,...

Embodiment 2

[0037] Such as image 3 As shown, the connecting assembly includes a fixed bracket 30 and an expansion bolt 31, and a through hole 32 is provided at the bottom of the fixed bracket 30, and one end of the expansion bolt 31 is nailed into the hole 3 on the natural rock matrix 1, and the other end passes through After the through hole 32 on the fixed support 30, screw the expansion bolt 31 with the nut 33 to fix the fixed support 30 on the natural rock matrix 1, and then fix the artificial algal reef 2 on the fixed support 30 to get final product. The specific operation of this method is as follows:

[0038]First adopt the larger cement board with attached seedlings as the artificial algae reef 2. First pour a cement board with 4 holes 34, the size is about 40*30*5cm, then spray seaweed spores on the cement board, after the spores are attached, according to the transplanting needs, when the seaweed grows to a certain size, it can be fixed to the Repair area. Adopt diving metho...

Abstract

The invention relates to a method for fixing algal reefs in manual transplanting. The method is used for fixing the algal reefs in the restoration work of a seaweed bed and includes the steps of using a percussion drill to drill natural reef matrix in a targeted sea area; and fixing the artificial algal reefs in various sizes and shapes onto the natural reef matrix through connecting components. By the aid of the underwater percussion drill for drilling and the connecting components, the artificial algal reefs which are mounted are firm, reliable and highly stable, and the artificial algal reefs in various sizes can be flexibly and conveniently fixed. The artificial algal reefs can be mounted at the proper positions according to the purposes of the seaweed bed, so that sediment prevention, light improvement, feeding prevention and water flow improving and the like can be effectively achieved. The artificial algal reefs are highly stable and controllable, and restoration and construction of the artificial seaweed bed can be achieved.

Description

technical field [0001] The invention relates to a fixing method for artificially transplanting algae reefs, especially in intertidal and subtidal rocky hard sea areas. The method of the invention can firmly install artificial algae reefs on the bottom of corresponding rocky reefs according to restoration needs. Fixed sea area, artificial algae reefs can be fixed at any water depth and any slope. Background technique [0002] In near-shore rocky bottom sea areas, artificial algae reefs are used to restore and build seaweed farms to improve the marine ecological environment and provide habitats for seabed fish. This is a method that has been widely used in recent years. However, due to the poor stability of the artificial algal reefs or high production costs, the limitations of the location of the algal reefs, and the restrictive conditions suitable for the growth of seaweed, the expected effect of artificial algal reef restoration algae sites is restricted. [0003] Most of ...
