Soil and water conservation method

Abstract

The invention provides a soil and water conservation method, comprising the following arrangement: a lawn nursery net body and a flexible framework system for supporting, connecting and fixing the lawn nursery net body; the lawn nursery net body is mainly formed by braiding rice straws, geotextiles and network materials into a flat and curve plexiform layer body in a way similar to needle seaming, the lawn nursery net body can be combined with a framework, or directly combined with part components of the flexible framework to form a hollow solid, the inner part of which can be filled with earth; the flexible framework is formed by the combination of an anchorage component, a multidirectional guilloche and a coupling member between the guilloche; the combination of the lawn nursery net body and the flexible framework mainly adopts the two ways: 1. the lawn nursery net body is firstly combined with components of the flexible framework, then is filled with soil and planted with grass after anchoring; 2. the flexible framework system is anchored and combined alone, meanwhile, the lawn nursery net body is filled with soil and planted with grass alone, then is moved to the flexible framework system to be combined. The invention has wide application scope and easy construction.

Description

1. Technical field [0001] The present invention relates to environmental protection engineering, in particular to a kind of transplanted vegetation that uses vegetation and cultivated plants independently or in combination on site, and becomes a three-dimensional shape after the construction is completed, which can be used on hillsides to protect vegetation, and has built structures, such as soil retaining The landscaping and greening of walls and embankments, as well as the water and soil conservation methods of combining building structures with subsidiary vegetation and greening. 2. Background technology [0002] There are many kinds of technical methods for soil and water conservation engineering, such as pre-stressed grid beam, free beam method, piling grid method, etc. The pre-stressed grid beam method is to use pre-stressed ground anchors to support the grid beam, and fill the hollow part of the grid beam with soil. , the free beam method uses bolts to anchor the latt...

AI Technical Summary

Problems solved by technology

[0003] Observing these water and soil conservation methods, there are basically the following shortcomings: First, planarization. On the whole, the surface completed by various methods is similar to a flat surface. The main reason is to reduce the complexity of construction. The size of the structure follows the construction along the slope, and because of the planarization, it is not conducive to soil conservation, making the slope vulnerable to erosion by rainwater and water flow, and reducing the vegetation efficiency of the slope. Therefore, it is often necessary to cooperate with relevant waterway measures to protect the construction results.

Secondly, the function is single. Unless there is a special matching method, the aforementioned soil and water conservation methods are generally only suitable for slope protection and cannot be used for other purposes, such as landscaping and greening of built structures.

The third is that there are many auxiliary matching processes. For example, the pre-stressed lattice beam method is a cast lattice beam. When the slope is high or standing alone, it is often necessary to build a construction beam frame to cooperate with the formwork of the lattice beam, the assembly of steel bars and the concrete casting work.

The fourth is that the slope is restricted. For example, when piling and weaving fence are on a steep slope, it is not only difficult to install bamboo and wood piles, but also the soil conservation effect is not good, which greatly reduces the vegetation effect.

The fifth is a lot of slope finishing work. In order to make the construction smooth and reduce the occurrence of falling rocks during or after the construction, it is often necessary to remove loose soil and rocks. The workload is often huge, and the removed soil and rocks are not easy to handle

Therefore, grass species with fast growth and deep root system are often used as the main species, and then tree species and local native plant species are introduced, that is, through the growth of grass species, the slope is stabilized to establish a planting base, and then various plants are introduced for greening and restoration. This method is easily affected by the climate, making it difficult to control the planting effect

Seventh, it is impossible to construct by transplantation. From the perspective of the structure of various soil and water conservation methods, it is quite difficult to cultivate various plants first, and then transplant them on the slope for planting. It is only feasible with special matching methods.

[0004] Although there are many existing water and soil conservation techniques, such as pre-stressed lattice beam method, free lattice beam method, piling and weaving grid method, etc., from the observation of their characteristics, various methods are planar structures, which are easily eroded by rainwater and water flow. Cooperate with related waterway projects to maintain the slope and vegetation effects, and the loose soil and rocks must be removed before construction, which increases the workload; in addition, due to the geometric shape of the slope, it is generally necessary to build a construction frame to facilitate the progress of each construction process At the same time, basically all kinds of methods only have a single purpose and it is difficult to use transplantation and planting methods for construction
