DETAILED DESCRIPTION

[0019] The technical scheme of the utility model is further described below, but the scope of protection is not limited to the description.

[0020] As Figures 1 to 4 shown.

[0021] The application provides a rockfill dam construction structure for guaranteeing panel construction slope, which comprises:

[0022] The side wall 1 is formed by dry-mixed concrete extrusion, the side wall 1 has an inclined surface 11 on the outer side of the dam body 2, and the side wall 1 has a vertical surface 12 on the inner side of the dam body 2.

[0023] The stockpile compacted layer 14 is compacted by a compactor, and the stockpile compacted layer 14 is close to the vertical surface 12 of the solidified part of the side wall 1.

[0024] The to-be-spread material pile 13 is poured by a transport vehicle, and the to-be-spread material pile 13 is close to the to-be-solidified part of the side wall 1.

[0025] When the material stockpile compaction layer 14 is compacted, the slope of the upper and lower slopes 11 of the sidewall 1 after solidification is consistent, ensuring the consistency of the inclination of the water-facing slope of each layer of the dam body 2.

[0026] This application provides a material spraying device for a rockfill dam, comprising:

[0027] The support feet 4 are fixedly installed on the transport road 3. The top of the support feet 4 is fixed with the mounting frame 5. The bottom of the mounting frame 5 is fixed with the slide rail 6, which consists of two parallel slide rails.

[0028] A slider 7 is slidably installed inside the slide rail 6. A water supply pipe 8 is fixedly installed on the slider 7 by a pipe clamp. There are multiple water supply pipes 8, and each water supply pipe is slidably installed on the slide rail 6 by two sliders 7. The bottom of the water supply pipe 8 has a nozzle 81 for water spraying. The water supply pipes 8 are fixedly connected to each other by a connecting plate 82. Deformable and retractable hoses (not shown in the figure) are connected to both ends of the water supply pipe 8 to transport water into the interior of the water supply pipe 8.

[0029] The connecting plate 82 is connected to a retractable telescopic component 9. The fixed end of the telescopic component 9 is fixed to the mounting frame 5, and the telescopic component 9 slides on the slide rail 6 along with the water supply pipe 8. Below the water supply pipe 8 with the nozzle 81, there is a transport road 3 for transport vehicles to travel on.

[0030] When a transport vehicle carrying the stockpiled material travels on the transport road 3 and passes under the water supply pipe 8 with nozzles 81, and needs to spray water on the stockpiled material, the telescopic component 9 slides on the slide rail 6 with the water supply pipe 8 with nozzles 81, synchronizing with the traveling transport vehicle. This increases the overlap time between the nozzles 81 and the transport vehicle on the transport road 3, thereby increasing the amount of water sprayed. This allows the transport vehicle to spray water on the transport road 3 without stopping, solving the problem of not being able to increase the amount of water sprayed while the vehicle is moving.

[0031] This application provides a method for constructing a rockfill dam body before panel construction, including:

[0032] Transport vehicles transport the stockpiled materials to the spraying device of the rockfill dam for spraying and watering. During this process, the sidewall 1 is formed by extruding dry-mixed concrete through extrusion equipment, so that the sidewall 1 has a sloping surface 11 on the outer side of the dam body 2 and a vertical surface 12 on the inner side of the dam body 2. The newly extruded sidewall 1 is on the upper layer, and the previously formed sidewall 1 is on the lower layer. The newly extruded sidewall 1 is on the dam body 2 and is constructed sequentially from the end closer to the transport road 3 to the end farther away from the transport road 3, so that the slope 11 of the upper sidewall 1 is consistent with the slope 11 of the lower sidewall 1.

[0033] The transport vehicle tilts to form a material pile 13 to be leveled. The material pile 13 is first leveled and then rolled by a roller to form a material pile compaction layer 14. The material pile compaction layer 14 is close to the newly extruded sidewall 1. The material pile compaction layer 14 is limited by the vertical surface 12. During the time it takes for the material pile compaction layer 14 to complete one layer, the upper sidewall 1 is solidified, ensuring the consistency of the slope of the newly extruded sidewall 1 on the upper layer with the slope of the previously formed sidewall 1 on the lower layer, presenting a rockfill dam construction structure that ensures the slope of the panel construction.
