The invention discloses an abrupt slope mountain photovoltaic micro pile foundation construction method under complex geological conditions, and relates to the technical field of photovoltaic foundation construction. According to the method, in order to solve the problems that the slope of the abrupt-slope mountain land is large, the terrain is complex, large machines are difficult to operate, and the ecological environment is sensitive, the structural form of small-diameter pile groups and chamfered triangular bearing platforms is adopted, the heavy-load unmanned aerial vehicle hoisting technology is combined, and minimally invasive, efficient and green construction is achieved. The core of the method comprises the steps of construction preparation, measurement positioning, hole forming, reinforcement cage and bearing platform reinforcement installation, material transportation based on the heavy-load unmanned aerial vehicle, concrete pouring, maintenance and the like. The method is high in environmental adaptability, capable of overcoming 15-45-degree abrupt slopes and complex geological conditions and greatly reducing earth excavation and vegetation damage, high in structural bearing capacity and low in manufacturing cost, solves the problems that a traditional construction method is low in efficiency, serious in ecological damage and the like, and is suitable for mountain photovoltaic power station projects, particularly suitable for photovoltaic foundation construction of ecological sensitive areas.

The utility model relates to the technical field of slope construction, concretely is a sand and stone transmission device for revetment, the device includes main truss, sand and stone transportation mechanism setting on main truss, the transverse walking mechanism of the main truss transverse movement can, the positioning mechanism of sand and stone transportation to the specified position, the device can transport sand and stone to the specified position of revetment, adapts to the backfill demand of different elevation, different position of revetment, improves sand and stone transportation efficiency, and the mechanical cost is low.

This invention provides a method for controlling Spartina alterniflora and promoting natural mangrove restoration based on rolling mulching and in-situ mud slurry, belonging to the field of ecological control technology. The method involves mechanically rolling Spartina alterniflora to flatten most of it and press it into the tidal flat soil. Then, a biodegradable mulch film is laid on top, and mud slurry is extracted and applied to form a mud slurry cover layer. A mangrove seed interception and planting device is then installed on the mud slurry cover layer to prevent mangrove seeds from growing naturally, thereby reducing the cost of Spartina alterniflora control and improving the efficiency of Spartina alterniflora control.

The utility model discloses a light-weight plastic formwork rapid assembling and moving device for a water conservancy project cast-in-place concrete structure, and relates to the technical field of water conservancy projects, in particular to the light-weight plastic formwork rapid assembling and moving device for the water conservancy project cast-in-place concrete structure. A plurality of lead screws are welded to the lower surface of the top beam, the surfaces of the lead screws are sleeved with formworks, inserting holes and clamping grooves are sequentially formed in the two sides of each formwork from top to bottom, and supporting steel pipes are inserted into the inserting holes. The formwork is made of light engineering plastic materials, compared with a steel formwork, the weight is greatly reduced, the manpower and mechanical cost in the transportation and installation process is reduced, and the construction efficiency is improved; the templates are quickly assembled, namely the templates are designed by adopting clamping grooves and clamping blocks, and are matched with supporting steel pipes, lead screws and top beams to be welded into T-shaped brackets, so that the templates are quickly and accurately assembled and supported, the assembling time of a construction site is reduced, and the construction period is shortened.
