Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0027] Pouring asphalt concrete to repair reservoirs is a common anti-seepage reinforcement measure that can improve the safety and stability of reservoirs. Asphalt concrete has good waterproof and mechanical properties, which can effectively prevent water from penetrating into the dam body. At the same time, it has certain crack resistance and deformation resistance, which can improve the bearing capacity of the dam body.

[0028] At present, the pouring asphalt concrete process is complicated, the construction efficiency is low, the cost is high, and during operation, floating objects and ice in the reservoir will collide and damage the asphalt concrete anti-seepage layer, seriously affecting the durability and safety of the asphalt concrete anti-seepage layer.

[0029] The present application first applies a prefabricated concrete hanging plate before pouring asphalt concrete. The assembled prefabricated concrete hanging plate can be used as a template for pouring asphalt concrete, which reduces the construction process, improves the construction efficiency, and saves the construction cost. The prefabricated concrete hanging plate is integrated with the poured asphalt concrete, which improves the anti-seepage and reinforcement effects, and also prevents various objects in the reservoir from directly damaging the asphalt concrete anti-seepage layer.

[0031] Reference Figure 1-Figure 4 As shown, the embodiment of the present application provides a prefabricated asphalt concrete hanging board for pouring, including a concrete board 1 and a structural steel bar 2 arranged on the concrete board 1;

[0032] The concrete slab 1 can be a square slab, the structural steel bar 2 is cast integrally with the concrete slab 1, the structural steel bar 2 has a dam body connection end extending out of the concrete slab 1, and the dam body connection end is connected to the reservoir dam body, so that the concrete slab 1 is parallelly fixed relative to the water-facing surface of the reservoir dam body, so that a casting gap is formed between the concrete slab 1 and the reservoir dam body, and the width of the casting gap can be adjusted according to the casting thickness of the asphalt concrete and the size of the structural steel bar 2;

[0033] Multiple concrete slabs 1 are fixed to the water-facing surface of the reservoir dam body through multiple structural steel bars 2. Multiple concrete slabs 1 are neatly and seamlessly assembled to form a wall panel that matches the water-facing surface of the reservoir dam body. Multiple casting gaps between the wall panel and the reservoir dam body form an asphalt concrete pouring area. The asphalt concrete is poured in the pouring area, thereby reducing construction procedures, improving construction efficiency, and saving construction costs. The prefabricated concrete hanging plate is integrated with the poured asphalt concrete, which improves the anti-seepage and reinforcement effects and also prevents various objects in the reservoir from directly damaging the asphalt concrete anti-seepage layer.

[0034] Reference Figure 2-Figure 4As shown, in some embodiments, the concrete slab 1 includes a water-facing concrete 11 and a water-receiving concrete 12, and both the water-facing concrete 11 and the water-receiving concrete 12 are square concrete slabs;

[0035] The dam body connecting end of the structural steel bar 2 extends out of the back surface concrete 12 and is connected to the reservoir dam body, so that the back surface concrete 12 and the reservoir dam body are relatively fixed, and the front surface concrete 11 and the back surface concrete 12 are cast in one piece, and the front surface concrete 11 is located on the back surface concrete 12 facing away from the reservoir dam body.

[0036] The water-facing concrete 11 and the water-receiving concrete 12 have the same height dimensions and are staggered in the height direction, so that the two ends of the concrete slab 1 in the height direction form a first water-facing connecting groove 13 and a first water-receiving connecting groove 14 respectively;

[0037] like Figure 3 As shown, the height dimensions of the water-facing surface concrete 11 and the back-facing surface concrete 12 are equal, but the two are staggered in the height direction, with the water-facing surface concrete 11 being located at the top and the back-facing surface concrete 12 being located at the bottom, so that the top end of the concrete slab 1 forms a first back-facing surface connecting groove 14, and the bottom end of the concrete slab 1 forms a first water-facing surface connecting groove 13.

[0038] The width of the water-facing concrete 11 and the water-receiving concrete 12 are equal, and they are staggered in the width direction, so that the two ends of the concrete slab 1 in the width direction form a second water-facing connecting groove 15 and a second water-receiving connecting groove 16 respectively;

[0039] like Figure 2 As shown, the width of the water-facing concrete 11 and the back-facing concrete 12 are equal, but they are staggered in the width direction, with the water-facing concrete 11 on the left and the back-facing concrete 12 on the right, so that the left end of the concrete slab 1 forms a second back-facing connection groove 16, and the right end of the concrete slab 1 forms a second water-facing connection groove 15;

[0040] In addition, the first water-facing surface connecting groove 13 and the second water-facing surface connecting groove 15 are connected to form an L-shaped connecting groove, and the first water-receiving surface connecting groove 14 and the second water-receiving surface connecting groove 16 are connected to form an L-shaped connecting groove. The L-shaped connecting groove design facilitates seamless assembly of adjacent concrete slabs 1.

[0041] Reference Figure 2 and Figure 3 As shown, in some embodiments, the structural reinforcement 2 includes a reinforcement skeleton and a connecting ring reinforcement 23, and the connecting ring reinforcement 23 can be ring-shaped or U-shaped;

[0042] The steel bar skeleton is cast in the concrete slab 1 and is located between the water-facing concrete 11 and the water-receiving concrete 12;

[0043] One end of the connecting ring steel bar 23 is a concrete connecting end, and the other end is a dam body connecting end. The concrete connecting end of the connecting ring steel bar 23 is fixedly connected to the steel frame, and the dam body connecting end of the connecting ring steel bar 23 is fixedly connected to the anchor bar drilled on the reservoir dam body.

[0044] The steel bar skeleton includes a plurality of upper steel bars 21 and a plurality of lower steel bars 22, and both the upper steel bars 21 and the lower steel bars 22 are straight steel bars;

[0045] A plurality of upper steel bars 21 are evenly distributed along the height direction of the concrete slab 1, and a plurality of lower steel bars 22 are evenly distributed along the width direction of the concrete slab 1. The upper steel bars 21 are located on the side of the lower steel bars 22 facing away from the reservoir dam body, and the upper steel bars 21 and the lower steel bars 22 are perpendicular to each other. The connected upper steel bars 21 and the lower steel bars 22 are tied and connected, so that the plurality of upper steel bars 21 and the plurality of lower steel bars 22 form a steel mesh.

[0046] According to the above technical features, the working principle of the cast asphalt concrete prefabricated hanging board provided by this application in the actual application scenario is:

[0047] Manufacturing prefabricated hanging panels: Place the upper steel bars 21 on the mold at the specified distance and position, tie the lower steel bars 22 to the upper steel bars 21 at the specified distance and position, and tie the connecting ring steel bars 23 to the upper steel bars 21 and the lower steel bars 22 at the specified distance and position; pour concrete on the basis of the tied structural steel bars, and ensure that the surface of the poured water-facing concrete 11 and the back-water concrete 12 is flat, regular, and uniform in size after prefabrication.

[0048] Trial assembly: When the prefabricated concrete panels are anti-seepage and reinforced for the reservoir dam, trial assembly is first carried out. During the trial assembly of the prefabricated concrete panels, the first water-facing surface connecting grooves 13 and the first water-receiving surface connecting grooves 14 of the two upper and lower adjacent concrete panels 1 are butt-jointed to form a whole, and the second water-facing surface connecting grooves 15 and the second water-receiving surface connecting grooves 16 of the two left and right adjacent concrete panels 1 are butt-jointed to form a whole, to ensure that multiple concrete panels 1 can be seamlessly assembled.

[0050] The present application sets structural steel bars 2 on the concrete slab 1, and the dam body connecting end of the structural steel bars 2 extends out of the concrete slab 1 and is connected to the reservoir dam body, so that a casting gap is formed between the concrete slab 1 and the reservoir dam body. Multiple concrete slabs 1 are fixedly assembled by multiple structural steel bars 2 to form a wall panel that matches the water-facing surface of the reservoir dam body. Multiple casting gaps between the wall panel and the reservoir dam body form an asphalt concrete pouring area, and asphalt concrete is poured in the asphalt concrete pouring area, thereby reducing the construction process, improving the construction efficiency, and saving the construction cost. Moreover, the prefabricated concrete hanging plate is integrated with the poured asphalt concrete, which improves the anti-seepage and reinforcement effects, and also avoids various objects in the reservoir from directly damaging the asphalt concrete anti-seepage layer.
