The utility model content

The purpose of this utility model provides a kind of shallow sea and encloses and cultivates structure, gathers materials on the spot, and finishes with extremely low cost and encloses and cultivates raising and the desalination target of soil, and it can be become at short notice can be for the general land resources of various exploitations.

In order to reach described effect, structure is enclosed and cultivated in a kind of shallow sea of the utility model, comprises dykes and dams, raises soil layer and artificial lake, raises the soil layer top layer and also is provided with the ditch network that is connected to artificial lake, and the ditch network reaches water table deeply.

Preferably, it is identical to raise the area of the area of soil layer and artificial lake.The direct like this earthwork that the excavation artificial lake can be produced be used for building raises soil layer.

Preferably, artificial lake connects dykes and dams, and is provided with ship lock on dykes and dams.Make and the current and the outer seawater circulation of dykes and dams of artificial lake keep current fresh.

Preferably, the degree of depth of described artificial lake is 3～8 meters.

Preferably, the water level of artificial lake is with at middle tide, so that water drainage.

Preferably, it is high 2～4 meters to raise soil layer.This highly can guarantee the ground of building or plant requiredly that it is minimum that relative cost also reduces to as far as possible.

Preferably, be provided with water balcony around the described artificial lake.When the utility model as the dwelling house soil, then water balcony can be built into the view platform, improve the class of dwelling house.And if artificial lake is built into the yacht harbour, then water balcony can be built into harbour, make things convenient for yacht to stop.

Preferably, it is high 4 meters to raise soil layer, and area is 500 mu.

Owing to adopted described technical scheme, the ditch network reaches water table deeply, just the salt in the soil can be taken in the artificial lake by rainwater like this.The desalination processes in soil can rely on rainfall fully and finish, and need not to irrigate, and can save great lot of water resources, and desalination processes is more all even rapidly.Artificial lake is the salt water lake, can be used for the sea-farming of agricultural, also can be used to build yacht wharf or keeps as view.Especially these are raised under the situation of soil layer as building land, the ditch network later stage can also be laid passage as of subsoil drain, kills two birds with one stone.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 encloses and cultivates the overall structure schematic diagram of structure for a kind of shallow sea of the utility model.

Fig. 2 encloses and cultivates the sectional view of raising soil layer of structure for a kind of shallow sea of the utility model.

The specific embodiment

As Fig. 1 and shown in Figure 2, structure is enclosed and cultivated in a kind of shallow sea of the utility model, is arranged on coastal beach area, comprises dykes and dams 1, is with in the dykes and dams 1 and raises soil layer 2, and raising soil layer 2 can be as agricultural production or as building land.Described raising is provided with artificial lake 3 in the soil layer 2, raise soil layer 2 top layers and also be provided with the ditch network 4 that is connected to artificial lake 3, ditch network 4 dark and water tables 5.After building well, ditch network 4 just can utilize the rainfall of coastal area nature to take away the salinity of raising in the soil layer 2.Generally such tract will being desalted alkalization needs time of 4-5, and the words by ditch network 4 then can be with within this time decreased to 1 year.So just strengthen land utilization ratio, also helped the recovery of fund.Especially these are raised under the situation of soil layer 2 as building land, 4 later stages of ditch network can also be laid passage as of subsoil drain, kill two birds with one stone.

The area of raising soil layer 2 is identical with the area of artificial lake 3.The earthwork that just can utilize excavation to produce when excavating artificial lake 3 is built and is raised soil layer 2 like this.The waste that energy maximum using land resources, and minimizing is like this brought is in transit reducingd the construction costs.

Artificial lake 3 connects dykes and dams 1, and is provided with ship lock 6 on dykes and dams 1.Such design mainly is to guarantee that lake water energy and dykes and dams 1 outer seawater in the artificial lake 3 circulate, and guarantee that current are fresh.Especially at artificial lake 3 during as the yacht bay, ship lock 6 is exactly a door of yacht turnover.

The degree of depth of described artificial lake 3 is 3～8 meters.Such degree of depth can satisfy the transportation of yacht, also can guarantee the normal operation in sea-farming base.The water level of artificial lake 3 is with at middle tide, so that water drainage.。It is high 2～4 meters to raise soil layer 2.Usually it is high 4 meters to raise soil layer 2, can also can use as building land as the agricultural planting land used.Be provided with water balcony 7 around the described artificial lake 3.When the utility model as the dwelling house soil, then water balcony 7 can be built into the view platform, improve the class of dwelling house.And if artificial lake is built into the yacht harbour, then water balcony 7 can be built into harbour, make things convenient for yacht to stop.Raise soil layer 2 and artificial lake 3 areas are set to 500 mu usually.A seabeach can be arranged to polylith exploitation like this, make things convenient for fund progressively to reclaim and the better utilization in soil.
