Microorganism reefing method of near-sea sand bank slope

Abstract

The invention discloses a microorganism reefing method of a near-sea sand bank slope. The microorganism reefing method of the near-sea sand bank slope is characterized by comprising the steps of constructing an appropriate microorganism carrier, artificially introducing mineralizable microorganisms into an original sand bank so as to form specified conditions, and promoting the microorganisms in the sand bank to induce metal cations in sea water so as to generate precipitates or form a biological film sandy reefing protection bank. According to the microorganism reefing method of the near-seasand bank slope provided by the invention, the characteristic that mineralized products or extracellular secretion polymers of organisms can be cemented with loose particles is utilized, a nature coral reef building process is simulated through a manual intervention manner, and bionic controlled reefing layers or blocks are formed, so that the usage of a traditional cement and other cementing materials is reduced and even abandoned; the microorganism reefing method of the near-sea sand bank slope is suitable for amplifying far-sea island reefs and reinforcing the near-sea sand bank slopes; anda construction method is simple, convenient to implement, and helpful to form a micro-ecological system.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a microbial reef-forming method for offshore sandy bank slopes. Background technique [0002] The ocean stores huge resources, and the development and utilization of ocean resources is a far-reaching energy strategic plan, and it is also a hot spot of competition among countries in the 21st century. With the proposal of the ocean power strategy, protecting and developing more than two million blue lands has become the task and goal of scientific and technological workers. [0003] Islands and reefs, as land on the ocean, are known as unsinkable aircraft carriers, not only as a supply station for national defense, but also as a logistics base for the development of marine resources. Natural islands and reefs and artificial islands and reefs formed by conventional dredging land reclamation methods are mostly sandy rock-soil media, which are easily eroded by w...

Problems solved by technology

[0006] Although this type of embankment has mature technology and reliable quality, its construction cost is extremely high. It is estimated that its construction cost is as high as hundreds of millions of yuan per kilometer, and the ecological and environmental problems caused by large-scale construction cannot be ignored.

For the construction of offshore islands and reefs, there are still problems such as difficult material transportation and poor construction conditions.
