The square frame structure pontoon 1 and the bar structure pontoon 12 are both fixed on the bearing plate through the connecting rope 6.

The floating plate is formed by compounding a PVC foaming plate 3 positioned on the upper layer and an XPS plate 2 positioned on the lower layer. Wherein the specification of the PVC foaming board is 2400 multiplied by 1200 multiplied by 15 or 2000 multiplied by 1000 multiplied by 15, and the specification of the XPS board is 2400 multiplied by 1200 multiplied by 50 or 2000 multiplied by 1000 multiplied by 50. Four floating plates are spliced into a bearing plate shaped like a Chinese character 'hui'. Small through holes 31 are uniformly distributed on the bearing plate, and the diameter of each small through hole 31 is 8 mm; the water absorbing ropes 4 are arranged in the small through holes 31, the center distance between adjacent small through holes is 40-80 mm, and the water absorbing ropes are determined according to the air drying degree of a use region and the moisture absorption condition of turf, for example, 60mm is suitable for the Shenzhen region. A square hole of 1200 × 1200mm or 1000 × 1000mm is formed in the middle of the bearing plate.

In the embodiment, the connecting rope 6 is a nylon cable tie; the water absorption rope 4 is made of purified fiber to ensure the same service life with other materials of the floating island. The water-absorbing cord 4 should be folded according to fig. 6 and inserted into the small through hole 31 of the carrier plate.

The planting box 5 is a stainless steel box body, and through holes 54 are formed in the bottom edge of the planting box 5 and on the side wall of a good person. Therefore, the planting box 5 can be made of a punched stainless steel plate.

As shown in fig. 6, the planting boxes 5 are planted with emergent aquatic plants, the horizontal dimension of which can be matched with the central square hole of the bearing plate, the planting boxes 5 are placed in the central square hole, the height of which is determined according to the plant height of the planted emergent aquatic plants 51 and is not less than the total height of the floating island main body. In order to meet the planting requirement of emergent aquatic plants 51, a layer of non-woven fabric 53 is arranged at the bottom of the planting box 5, and soil 52 is paved on the non-woven fabric.

All components manufactured according to the above characteristics are relatively easy to transport in size. The water absorption rope and the like which do not affect the transportation are well installed in a production plant, and when the water absorption rope is installed, the position of the buoy is marked in advance, and the position of the connecting rope for bundling is marked.

The utility model discloses an assemble the step as follows:

1) splicing the four floating plates according to the positions shown in the figure 3, wherein the splicing seams are positioned and connected by adopting porous stainless steel sheets to form a bearing plate;

2) fixing the floating barrel on the floating island bearing plate by adopting a connecting rope to form a floating island main body;

3) turning over the floating island body by 180 degrees, and then putting the floating island body into water;

4) placing the planting box into a central square hole of the bearing plate;

5) the kind of the filling or soil in the planting box is selected according to the kind of the plant, and the filling or soil is filled into the planting box according to the method shown in fig. 6, and then the plant is planted.

6) And laying a layer of planting soil on the bearing plate, and then laying turf.

7) The utility model discloses the part that can produce bearing buoyancy has two types: the buoy comprises a square frame structure buoy, a strip structure buoy and a bearing plate formed by splicing 4 floating plates.

The utility model discloses a theory of operation:

firstly, a bearing principle:

the floating pontoon is completely immersed under water when working, and the buoyancy of the floating pontoon can meet the static load requirement of the floating island. The static load includes the weight of the buoy and the load bearing plate themselves, the weight of the soil and turf on the load bearing plate, the planting box, and the calculated weight of the soil and plants in the box. When all the static loads are installed in place, the lower surface of the bearing plate should be in contact with the water surface, otherwise, the thickness of the turf planting soil layer should be increased properly. The bearing plate is used for bearing static loads such as the weight of soil and turf on the bearing plate, the calculated weight of the planting box and soil and plants in the planting box, but is not immersed in water at ordinary times, so that buoyancy is not generated at ordinary times. The lower plate of the composite plate is made of XPS plate, and once dynamic load (people or temporarily stacked objects) is applied, the XPS plate is immersed in water, so that great buoyancy is generated to support the dynamic load. One side of the floating island is pressed into water in a short time to soak the turf with water, so that the growth of the turf is not influenced. The dynamic load design meets the requirements of personnel on-island maintenance operation, leisure and appreciation and the like.

Irrigation-free water supply principle

A large number of water absorbing ropes are evenly distributed on the bearing plate, and after the turf is planted, water sources in the water body can be continuously transmitted to the planting soil layer through the water absorbing ropes, so that irrigation-free water supply is realized.

Third, principle of water purification

Because the planting box 4 is made of punched stainless steel plates, the water level inside the box body is consistent with the water level outside the box.

When emerging plants are planted, the emerging plants can play a role in purifying water quality like other emerging plants in a water body.

The utility model discloses according to the volume of live load and the volume of dead load demand design flotation plate thickness and flotation pontoon, can make not go up the man-hour plant on the loading board can obtain moisture through the rope that absorbs water, be favorable to vegetation and realized exempting from to irrigate the water supply. The XPS board and the PVC foaming board are compounded to be made into the floating board, the PVC foaming board on the upper layer of the bearing board has enough strength and rigidity, and the XPS board on the lower layer has enough buoyancy. The four floating plates are spliced into the floating island bearing plate, so that a board with a standard size can be utilized to the maximum extent, the manufacturing cost of each square meter of the floating island is reduced, the service life of the material is long, and the product is economical and applicable. The stainless steel planting box is designed to be capable of planting higher emergent aquatic plants or common terrestrial plants, turf is planted at the edge of the floating island, and low terrestrial plants are planted between the planting box and the turf. The whole floating island is more like an island in shape, so that birds can inhabit, a relatively natural ecological environment is formed, biological diversity is realized, and a landscape effect is good. The dynamic load design can be maintained by people and can be used for leisure and entertainment.

Example 2

As shown in fig. 4, the outer edge of the carrier plate is a curved edge 32.

In order to increase the fixing stability among the four floating plates of the bearing plate, the abutted seams of the four floating plates can be positioned and connected or reinforced by adopting porous stainless steel sheets.

The rest of this example is exactly the same as example 1.
