Description

The alkaline land improving facility
Technical field
The utility model relates to a kind of alkaline land improving facility.
Background technology
Along with coastal great development, many new coastal cities are rised sheer from level ground, but the development of Xincheng District is being perplexed in coastal saline land, newly constructs the factory buildings, dwelling house, road two sides be without landscape planting, city taste, and investment environment can not improve.In order to improve the Xincheng District environment, the general using farmland is good native, replaces the plantation greening, also has use to carry out draining with a large amount of stones laying pouring layers and improves the soil.But cost is larger, and some can not be implemented by conditionality, and the hyperphoric saline-alkali soil that can not reach of soil moved in to improve the original effects a radical cure effect.Therefore, the weather advantage rainy according to the area need to provide a kind of and can effectively effect a radical cure the saline land, makes the solonchak of improvement reach the solution of plant normal growth condition.
Summary of the invention
The purpose of this utility model provides a kind of alkaline land improving facility.
The technical solution adopted in the utility model is:
The alkaline land improving facility, formed by at least one unit, each unit is equipped with foundation trench, the described foundation trench two ends degree of depth does not wait, described foundation trench wall is covered with waterproof Polypropylence Sheet, described foundation trench bottom even interval has french drain, be covered with the infiltration nonwoven in the described french drain to the french drain outside, arch form face between the described french drain is covered with waterproof Polypropylence Sheet, be placed with blind pipe in the described french drain, described blind pipe wraps up without gauze with the anti-mud of infiltration, be covered with coarse sand or particulate rubble in the described french drain around the blind pipe, the high side blind pipe of described foundation trench bottom french drain extends the foundation trench surface, and a blind pipe low side in described foundation trench bottom connects gully, described foundation trench surface is covered with the organic horizon of one deck 25-35cm, is provided with embankment above the described organic horizon.
Being covered with in the described french drain the anti-mud of infiltration without gauze to the french drain outside, insert the clean rubble of infiltration nonwoven parcel in the described french drain, the high side of described foundation trench bottom french drain arranges the PVC plastic tube, the lower end is stretched in the stone, and is suitable for reading to the earth's surface.
Described organic horizon is by crushing straw, rice husk, beans shell and native full and uniform stirring.
Described blind pipe is PVC perforated plastic pipe, the pipe tap diameter 0.8-1.2cm on the described perforated plastic pipe.
The utility model has the advantages that: during impeded drainage, insert high-pressure water pipe and wash away mud, guarantee that drainpipe is unimpeded, during arid, drainage outlet is stopped up, pour water, raise the water drought resisting; Be provided with organic horizon, make soil penetrating, be convenient to the draining salt reduction, increase the soil organic matter after rotting; Be provided with embankment, accept natural rainfall, plant fast such as little the need again of rainfall, available fresh water pouring detects the blind pipe discharge water, when reaching requirement, stops the desalinization of soil by flooding or leaching, can effectively improve utilization to saline-alkali soil, improves plant percent.
