AI Technical Summary
Existing rockfill dam material paving technology cannot guarantee the consistency of the inclination of each layer of the water-facing slope.
The sidewalls are constructed by extruding dry-mixed concrete, and the slope of the sidewalls is ensured by using a roller and spraying equipment in conjunction with transport vehicles. The construction process of unloading the material pile to be leveled and compacting the layers by transport vehicles is combined to achieve uniformity of the water-facing slope of each layer.
This effectively ensures the consistency of each water-facing slope of the rockfill dam, and improves the quality and precision of the material compaction.

[0001] The utility model relates to a kind of rock-fill dam construction structures for ensuring panel construction gradient, rock-fill dam body construction technical field. BACKGROUND
[0002] Rock-fill dam body is formed by material layering and rolling, and since dam body of layering and rolling needs to be installed with concrete panel in later period, the gradient of each layer of dam body after forming needs to be ensured consistent.
[0003] The existing rock-fill dam material spreading technology is disclosed in Chinese patent CN114657945A, which discloses that dry-hard mixed material is transported to dam filling site by self-unloading truck, and then spread, leveled and rolled. Although the material spreading and rolling can form dam body, the gradient of each layer of dam body cannot be ensured consistent. SUMMARY
[0004] To solve the above technical problems, the utility model provides a kind of rock-fill dam construction structures for ensuring panel construction gradient.
[0005] The utility model is implemented by the following technical solutions.
[0006] The utility model provides a kind of rock-fill dam construction structures for ensuring panel construction gradient, which comprises:
[0007] The side wall has inclined surface and vertical surface on both sides, and the gradient of the inclined surface of the upper layer and the lower layer of the side wall is consistent.
[0008] It also includes a to-be-spread material pile poured by a transport vehicle, which is close to the to-be-solidified side wall part.

[0011] The utility model has the advantages that the side wall is made of extruded dry-mixed concrete by extrusion equipment, so that the side wall presents inclined surface towards the outer side of the dam body and presents vertical surface towards the inner side of the dam body.

DETAILED DESCRIPTION
[0017] The technical scheme of the utility model is further described below, but the scope of protection is not limited to the description.
[0018] As Figures 1 to 4 shown.
[0019] The rock-fill dam construction structure for guaranteeing the slope of panel construction provided by the application comprises:
[0020] 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. The slopes of the inclined surfaces 11 of the upper layer and the lower layer of the side wall 1 are consistent. The side wall 1 far from the transport road 3 solidifies earlier, which is called the solidified part.
[0021] The stockpiling compacted layer 14 is compacted by a roller compactor, and the stockpiling compacted layer 14 is close to the vertical surface 12 of the solidified part of the side wall 1.
[0022] 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.
[0023] When the stockpiling compacted layer 14 is compacted to one layer, the slopes of the inclined surfaces 11 of the upper layer and the lower layer of the solidified side wall 1 are consistent, which guarantees the consistency of the slope of each layer of the water-facing inclined surface of the dam body 2, and solves the problem that the stockpiling direct spreading and compacting can form the dam body, but cannot guarantee the consistency of the slope of each layer of the water-facing inclined surface.
[0024] The stockpiling spraying device of the rock-fill dam provided by the application comprises:
[0025] Supporting legs 4 are fixedly installed on the transport road 3, and the top of each supporting leg 4 is fixed with a mounting frame 5, and the bottom of the mounting frame 5 is fixed with slide rails 6 which are two parallel slide rails.
[0026] Sliding blocks 7 are slidably installed in the slide rails 6, and water supply pipes 8 are fixedly installed on each sliding block 7 through pipe clamps. Each water supply pipe 8 is slidably installed on the slide rails 6 through two sliding blocks 7, and the bottom of each water supply pipe 8 is provided with a spray head 81 for water spraying. The water supply pipes 8 are fixedly connected through connecting plates 82. Deformable and contractible hoses (not shown in the figure) are connected to the two ends of the water supply pipes 8 for conveying water into the water supply pipes 8.
[0027] The connecting plates 82 are connected with telescopic members 9, the fixed end of each telescopic member 9 is fixed on the mounting frame 5, and the telescopic member 9 slides on the slide rails 6 with the water supply pipes 8. The water supply pipes 8 with the spray heads 81 are below the transport road 3 for the running of the transport vehicles.
[0028] When the transport vehicles need to spray water on the material piles, the telescopic members 9 slide on the slide rails 6 with the water supply pipes 8 with the spray heads 81 to be synchronous with the running of the transport vehicles, so that the spray heads 81 coincide with the transport vehicles on the transport road 3 for a longer time to increase the amount of water spraying, and the transport vehicles can spray water without stopping on the transport road 3.
[0029] The face plate construction method for the dam body of the rock-fill dam before construction provided by the present application comprises the following steps:
[0030] The transport vehicles transport the material piles to the material pile spraying device of the rock-fill dam to spray water. In this process, the side wall 1 is extruded by the extrusion equipment to form the dry mixed concrete, so that the side wall 1 presents an inclined surface 11 on the outer side of the dam body 2 and presents a vertical surface 12 on the inner side of the dam body 2. The newly extruded side wall 1 is on the upper layer, and the previously formed side wall 1 is on the lower layer. The newly extruded side wall 1 is on the dam body 2 and is sequentially constructed from the end close to the transport road 3 to the other end away from the transport road 3, so that the inclination of the inclined surface 11 of the upper layer side wall 1 is consistent with the inclination of the inclined surface 11 of the lower layer side wall 1.
[0031] The transport vehicles dump the material piles to be flattened 13, the material piles to be flattened 13 are flattened first, and then are rolled by the roller to form the material pile rolling layer 14. The material pile rolling layer 14 is close to the newly extruded side wall 1, and the material pile rolling layer 14 is limited by the vertical surface 12. During the time period of rolling one layer of the material pile rolling layer 14, the upper layer side wall 1 is solidified to ensure the consistency of the inclination of the newly extruded side wall 1 on the upper layer and the inclination of the previously formed side wall 1 on the lower layer, thereby realizing the rock-fill dam construction structure for ensuring the inclination of the face plate construction.
