Embodiment 1

[0054] This embodiment proposes a prefabricated high-performance concrete-photovoltaic pavement structure suitable for asphalt pavement, which at least includes: subgrade, base layer, asphalt surface layer, and combined power generation functional layer arranged sequentially from bottom to top. Among them, the combined power generation functional layer is composed of an ECC stress layer and a photovoltaic panel layer, and there is an extremely thin bonding layer between the ECC stress layer and the surface layer and the solar photovoltaic power generation layer.

[0055] The roadbed 7 can be a soil roadbed in accordance with the provisions of my country's "Highway Roadbed Design" (JDGD30), and the roadbed should be stable, dense and homogeneous, so as to provide uniform support for the road surface structure. The technical indicators of the subgrade should comply with the provisions of my country's "Technical Specifications for Highway Subgrade Construction" (JTJF10).

Embodiment 2

[0067] This implementation is based on a prefabricated ECC photovoltaic pavement structure described above, and proposes a construction method, including the following steps:

[0068] 1. The specific steps for the prefabrication of the ECC board are as follows:

[0069] (1) Reserve the junction box by arranging rectangular pads on the prefabricated formwork, and reserve the position of the arched drainage structure in the form of prefabricated formwork. Arrange vertical and horizontal structural steel bars according to the design drawings, in which the longitudinal bars are arranged on the upper part of the horizontal bars, and the contact positions should be fixed with steel bars. And weld the hoisting components at the end of the transverse reinforcement.

[0070] (2) Weigh a sufficient amount of cement, fly ash, quartz sand, fiber and other materials and mix them with an ECC mixer.

[0071] (3) After the materials are mixed evenly, pour the ECC into the formwork prepared ...

Embodiment 3

[0081] According to the process of embodiment 2, the photovoltaic pavement is laid, and when the pavement is damaged and needs to be repaired, the implementation steps are as follows:

[0082] (1) If the photovoltaic panel is damaged and loses its road use function, the damaged panel should be removed and replaced with a new one, and the pipeline connection should be restored to the damaged panel for subsequent repair. The specific steps are as follows:

[0083] 1. Take out the electric resistance wire interface reserved in advance from the edge of the photovoltaic panel to be removed, connect it to an external power source, and heat it until the adhesive material is heated and melted, showing a fluid state.

[0084] 2. Remove the damaged photovoltaic panel carefully, and be careful not to damage the junction box and the connected lines in the pipeline ditch.

[0085] 3. Fill or grind the lower ECC layer corresponding to the board, and re-level it.

[0086] 4. Reconnect the n...

Abstract

The invention discloses a prefabricated asphalt concrete-photovoltaic power generation pavement structure and a method. The prefabricated asphalt concrete-photovoltaic power generation pavement structure comprises a subgrade, a base layer, an asphalt concrete surface layer and a combined power generation functional layer which are arranged from top to bottom in sequence; the combined power generation functional layer comprises prefabricated plate units; each prefabricated plate unit consists of a plurality of photovoltaic panels and an ECC plate; after the plurality of photovoltaic panels areconnected in series, the photovoltaic panels are positioned at the top of the ECC plate and the photovoltaic panels are bonded to the ECC plate through a bonding layer to form a whole; constructionalreinforcing steel bars are arranged in the ECC plate; a temperature joint is formed between adjacent photovoltaic panels and is used for deformation of the photovoltaic panels; a temperature joint isreserved between adjacent prefabricated plate units and is used for deformation of the prefabricated plate units; the temperature joint is filled by an elastic material with high elasticity; and height transverse and longitudinal arch drainage facilities are uniformly prefabricated at the bottom of the ECC plate.

Description

technical field [0001] The invention discloses an assembled asphalt concrete-photovoltaic generating surface structure and a construction method. Background technique [0002] At present, photovoltaic power generation surfaces are applied to varying degrees in the United States, China, the Netherlands, France and other countries. However, during the construction and repair process of photovoltaic pavement, because the existing laying technology is mainly manual laying, and the laying of electrical components and the circuit connection between photovoltaic panels need to be carried out many times during the laying process, it is faced with cumbersome procedures, complicated processes, and energy consumption. It takes a long time and the original road surface needs to be milled and cut many times, which will cause great damage. In addition, during the disassembly and replacement of photovoltaic panels, the photovoltaic panels need to be manually dismantled, which not only slo...
