Ecological slope protection vegetation building blocks as well as making method and construction process

The present invention relates to a building block of ecological slope protection vegetation, a fabrication method and a construction technique. The building block is composed of a growing bed body, a lath crib, planting troughs, a vegetation layer and a plant, the lath crib wraps the circumference of the growing bed body, the upper plane of the growing bed body is lower than the upper plane of the lath crib and concave, the vegetation layer is formed on the growing bed body, which matches the inner walls of the sectional area of the lath crib to form an integral building block, and more than one planting troughs are arranged on and run through the growing bed body. The design of the present invention is scientific, the structure is reasonable, the restoration of water ecology can reduce the operating cost, environment is improved, ecology is reinstated, harmonious natural beauty is enhanced, and the present invention is suitable for the nidification of small living creatures and the habitation and the survival of aquatic fishes, so that the cutting-off continuity of water and land regions is restored. The present invention is widely applied to channel slope protection, levee slopes, roadsides, airports, parks, public lands, household lawns, sports grounds, etc. The present invention is suitable for cold regions, damp regions, warm and damp intermediate zone, etc.

Guided tissue regeneration membrane and its preparation method

The invention relates to a guided tissue regeneration membrane, which comprises a compact coating and a loose coating, wherein the compact coating is composed of collagen-I or collagen-I composite hyaluronic acid; and the loose coating is composed of collagen-I or collagen-I composite calcium salt. A preparation method of the guided tissue regeneration membrane comprises the following steps of: preparing a collagen solution or a collagen and hyaluronic acid mixed solution by the use of acetic acid; injecting the solution into a self-made die, and drying it in the air to prepare the compact coating; injecting the collagen solution or a mixed liquor of the collagen solution and calcium salt onto the compact coating, and uniformly spreading; precooling the die at ultralow temperature, followed by freeze-drying to prepare the guided membrane with the compact coating and loose coating structure; carrying out vacuum high-temperature crosslinking and chemical crosslinking; and finally cleaning. The regeneration membrane has good histocompatibility and mechanical strength, low antigenicity and strong guided tissue regeneration capability. Its degradation rate in vivo is 3-8 months. The method is easy to operate, is suitable for automatic and continuous large-scale production, and solves the problems of large size of collagen membrane and material uniformity during industrial production.
