This regulation is formulated in accordance with the notification
requirements of the “Construction and Revision Plan for the Second Batch of
Engineering Construction Associations in 2011” by the China Engineering
Construction Standardization Association.
The ecological grid structure
is a flexible structure in which the grid assembled into a grid is filled with
the required bulk material. It originates from the ancient bamboo cage and sheep
ring structure, and is mainly used for revetment or retaining facilities, which
is characterized by ensuring slope protection. It has the safety and durability
while taking into account the environmental and ecological effects of the
project, in order to achieve a kind of soil and biological mutual conservation,
suitable for the natural state of biological growth. The eco-grid has the
following features:
1. Safety: The ecological grid structure is a kind of
whole and water-permeable structure. It not only has flexibility, adapts to
basic deformation, but also resists wind and waves, and is resistant to erosion.
It can effectively slope and protect slopes;
2. Ecology: The ecological grid
structure has high porosity and high water permeability. The soil, water body
and organisms are mutually cultivated, which does not affect the habitat of the
original organisms. After the construction is completed, it can be accepted by
native organisms.
The ecological grid structure has been applied to the
water conservancy and transportation industries for nearly 100 years in the
world. It has accumulated some mature experience. On the basis of a large number
of applications in the western countries, the American Materials and Testing
Association and the European Standards Committee have successively compiled
Relevant standards have standardized the materials of the ecological grid
structure. China has researched and developed this technology in the 1990s.
After nearly 20 years of practice, it has accumulated some successful
experiences, but it also exposed problems such as insufficient design basis and
inadequate construction. In order to make the ecological grid structure
standardized in water conservancy, transportation, municipal, garden, waterway
and other industries, this technical regulation has been formulated.
This
technical specification mainly includes: general rules, terminology and symbols,
materials, classification and design standards, structural classification and
structural arrangement, design of ecological grid Gubin retaining wall, design,
construction, quality inspection of ecological grid green slope protection
Evaluation, a total of 9 chapters and 2 appendices.
