Disclosed are a cement coating for inducing the settlement of marine sessile organisms and an application technology therefor, and, in particular, a construction method for an ecological riprap breakwater, an induced cement-based coating, and a preparation method thereof. The cement coating for inducing the settlement of marine sessile organisms is coated on surfaces of rocks, and a reasonable spatial layout is applied, such that each rock pile (block) can effectively break waves and ensure smooth exchange between water bodies on two sides. After oysters attached to each rock pile (block) breed a large amount, the water bodies can be purified, and the ecological environment in the surrounding sea area can be improved.

A method for fabricating a retaining wall configured to extend into a ground comprising the steps of providing at least a first longitudinal support having a receiving part and extending along a first longitudinal direction; placing the first longitudinal support transversely to the ground; providing at least a first module comprising a longitudinal element and a first wing; positioning the first module parallel to the first longitudinal support; connecting the first module to the first longitudinal support, so that the first wing of the first module is slidably engaged with the receiving part of the first longitudinal support; then moving said first module in translation along the first longitudinal direction, and sinking said first module into the ground and then the first longitudinal support into the ground.
