Description

Floating island for integrally transplanting plant community in reservoir area

Technical Field

The utility model provides a carry out the chinampa device that whole was transplanted with reservoir area plant in hydraulic and hydroelectric engineering construction process belongs to hydraulic and hydroelectric engineering environmental protection field.

Background

During the construction of the reservoir, a large land area at the upstream can be submerged to form a reservoir area. Important protection plants need to be transplanted in the reservoir area. The traditional transplanting mode is generally adopted for transplanting single plants or scattered plants. And (4) keeping the root system of the plant as much as possible, separating the root system of the plant from the soil, and transporting the plant to a protected area for transplanting. However, it is difficult to individually transplant a large number of plants having strong landscape effect or special habitat. On one hand, the transplanting cost of a single plant is very high, and the transplanting of a large number of plants is often day price; on the other hand, the transplanting survival rate cannot be guaranteed, the roots of a large number of plants are entangled with each other, and the roots of different plants cannot be clearly and clearly separated, so that the root loss is large, and many plants cannot survive after transplanting due to root damage; more importantly, the original habitat and landscape cannot be guaranteed after the transplanting is carried out in a single-plant transplanting mode, and the original habitat and landscape value are difficult to guarantee.

Some plants occupy an important ecological position in river reach habitats near reservoir areas. Even if the transplanting is carried out, the vicinity of the river reach is selected for the migration. Mainly avoid flooding caused after retaining water. For greening and ecological protection around the reservoir area, it is of course the best mode of protection to be able to use locally protected plants.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: a device for transplanting the flaky plants in the reservoir area.

The utility model discloses a chinampa for whole transplantation of reservoir area plant community includes particularly: the device comprises vertical connecting pipes, horizontal connecting pipes, a plant structure body bottom plate, a replacement structure body, a supporting platform, light steel round piles, a sealing steel plate and a buoyancy tank device.

The plant structure body, the plant structure body bottom plate, the replacement structure body and the supporting platform are connected with each other through the vertical connecting pipe, the plant structure body is arranged on the upper layer, and the replacement structure body is arranged on the lower layer; the thickness of the plant structural body is 1.5 times of the theoretical transplanting excavation depth; the thickness of the replacement structure body is calculated according to the theoretical weight of the plant structure body, so that the buoyancy provided by the replacement structure body can meet the buoyancy required by the floating island, and the extra 15% of buoyancy is provided as safety redundancy; the support platform is arranged at the lower part of the replacement structure body and is made of concrete materials.

Arranging a horizontal connecting pipe at the bottom of the plant structure body; the plurality of horizontal connecting pipes penetrate through the whole floating island range in the horizontal direction; the horizontal connecting pipe adopts the steel pipe, and the steel pipe itself provides the structure holding power for the body, and horizontal connecting pipe diameter is no longer than 2m, and horizontal connecting pipe inside adopts the post to support.

The periphery of the plant structure body is sealed by sealing steel plates, and a prestressed anchor rod is adopted between the sealing steel plates for anchoring; and a light steel round pile is adopted to support in the longitudinal direction in the replacement structure body.

The floating box device is connected to the periphery of the floating island and welded to the floating island through the horizontal connecting pipe to form a part of the floating body of the floating island, so that the floating and balance of the floating island are facilitated.

The beneficial effects of the utility model reside in that:

1. the floating island for integrally transplanting plants provided by the utility model can protect a plurality of plants together, keep the original plant pattern and keep the original environment to the maximum extent;

2. the utility model can keep and protect the original habitat of the river reach to a certain extent, reduce the transplanting investment and improve the transplanting survival rate;

3. because the utility model discloses a solidify and float original soil body of reservoir, can be under construction to the chinampa simultaneously when carrying out hydraulic engineering construction, save the time limit for a project, practice thrift the cost, be convenient for on-the-spot whole dispatch.

Detailed Description

The embodiments are described below in conjunction with the accompanying drawings and the present invention is described in detail.

Example one

A floating island for the integral transplantation of plant community in a reservoir area comprises: the device comprises a vertical connecting pipe 3, a horizontal connecting pipe 4, a plant structure body 5, a plant structure body bottom plate 6, a replacement structure body 7, a supporting platform 8, a light steel round pile 9, a sealing steel plate 10 and a buoyancy tank device 11. The relative positions of the plant structure 5, the plant 1 and the floating island range 2 are shown in figure 1.

The plant structure body 5, the plant structure body bottom plate 6, the replacement structure body 7 and the supporting platform 8 are connected with each other through the vertical connecting pipe 3, the plant structure body 5 is arranged on the upper layer, and the replacement structure body 7 is arranged on the lower layer; the thickness of the plant structural body 5 is 1.5 times of the theoretical transplanting excavation depth; the thickness of the replacement structure body 7 is calculated according to the theoretical weight of the plant structure body 5, so that the buoyancy provided by the replacement structure body 7 can meet the buoyancy required by the floating island, and the extra 15% of buoyancy is provided as safety redundancy; the supporting platform 8 is arranged at the lower part of the replacing structural body 7 and is made of concrete materials.
