Description
Technical field
The utility model belongs to Saline-alkali Field Control field, and in particular to it is a kind of effectively prevent the accumulation of salt in the surface soil every salt deposit structure.
Background technique
In recent years, coastal region has become the critical position of China's development " blue is economic ", studies changing for beach saline land
Good greening technique has great significance to urban construction and development.In coastal region saline land greening engineering, alkaline land improving effect
The quality of fruit, is directly related to that can plant survive and can soil property meet the needs of plant growth for a long time, is engineering success or failure
Deciding factor.
Traditional salt discharge alkali measure is usually to replace soil, but for coastal region, be on the verge of sea area, moisture-salt transport frequency
Numerous, displaced soil is likely to occur accumulation of salt in the surface soil phenomenon with moisture-salt transport.
Summary of the invention
In view of the problems of the existing technology, the utility model provide it is a kind of effectively prevent the accumulation of salt in the surface soil every salt deposit structure, lead to
Salt discharge is crossed except the laying of alkali drenching layer effectively prevent the accumulation of salt in the surface soil, compensates for the deficiency of conventional method.
To achieve the above object, the utility model uses following technical scheme:
It is a kind of effectively prevent the accumulation of salt in the surface soil every salt deposit structure, which includes base soil layer, excavate groove in the base soil layer,
It is laid with coarse sands layer in the trench, several Pipe for draining alkali are laid in the coarse sands layer, the Pipe for draining alkali is obliquely installed, described
The discharge ends of Pipe for draining alkali are connected with municipal inspection shaft, geotextiles have been externally wrapped in the Pipe for draining alkali, on the base soil layer
It is equipped with metalling, salinity barrier layer is laid on the metalling, is backfilled with planting soil layer above the salinity barrier layer, institute
Metalling and the composition salt discharge of salinity barrier layer are stated except alkali drenching layer.
The Pipe for draining alkali is the HDPE double-wall corrugated pipe that the DN equipped with inlet opening is 100mm, the cross between adjacent Pipe for draining alkali
It is 25mm to spacing, the inlet opening is bar shaped inlet opening, and the length and width of bar shaped inlet opening is having a size of 80mm*6mm.
The gradient of the Pipe for draining alkali is not less than 0.5%.
The geotextiles are double-layer structure, geotextiles 200g/m2, the geotextiles are using steel wire lashing outside Pipe for draining alkali
Portion.
D is used to connect for the HDPE double-wall corrugated pipe of 200mm between the discharge ends of the Pipe for draining alkali and municipal inspection shaft.
The metalling is 10-30mm with a thickness of 200mm, the partial size φ of medium stone.
The salinity barrier layer with a thickness of 50mm, the salinity barrier layer is to roll straw layer or roll wheat straw grass layer.
The HDPE double-wall corrugated pipe pipe ring stiffness is not less than 8KN/m2。
Compared with prior art, the utility model has the following beneficial effects:
The utility model structure strong operability, high suitable for each department level of ground water, big, the easy salification of salinity ground
Area raises level of ground water because river water side is seeped, promotes salification such as river and the soil of channel both sides.Coastal area is because of seawater
Dipping, can form coastal saline-alkali soil, beach saline land etc..
The utility model can significantly improve salt-soda soil every the laying of salt deposit structure, in order to which salt water is isolated from plant for a long time
Other than the soil of growth scope, after base's earth excavation, plantation earthen backfill before bottom be laid with can water supply and sewage pipeline, on
Rubble, lid straw or straw grass are spread, is made it possible to the salinity in soil in rainy season precipitation with water inflow pipe, and pass through rubble
The salinity that straw etc. prevents dry season moisture from returning up when evaporating with water, finally backfills planting soil again, then just forms together
Salt discharge removes alkali drenching layer, and salt discharge removes the laying of alkali drenching layer, the saline-alkali water drained in order to prevent accumulation of salt in the surface soil because of water level rising.Salt discharge removes
Alkali drenching layer can also effectively block salt ground water along soil capillary interstice rise, by Groundwater Control critical depth with
Under, to achieve the purpose that Soil Desalting and prevent the accumulation of salt in the surface soil, to compensate for the deficiency of conventional method.
