The invention discloses a reservoir dam bay-by-bay casting formwork. The formwork comprises two formwork assemblies. Each formwork assembly comprises a main formwork body and an auxiliary formwork body, wherein a plurality of compression springs are arranged between the main formwork body and the auxiliary formwork body; and the top and bottom of the main formwork body are connected with sliding blocks through slipknot hinges correspondingly. A first transverse rod is arranged between the two corresponding sliding blocks at the tops of the main formwork bodies in an inserting mode. A second transverse rod is arranged between the two corresponding sliding blocks at the bottoms of the main formwork bodies in an inserting mode. Both the first transverse rod and the second transverse rod are in threaded connection with the sliding blocks correspondingly. The portions, located on the outer sides of the sliding blocks, of the transverse rods are sleeved with positioning shaft sleeves correspondingly. The portions, located on the inner sides of the sliding blocks, of the transverse rods are sleeved with positioning nuts correspondingly. According to the reservoir dam bay-by-bay casting formwork, through the arranged main formwork bodies and the auxiliary formwork bodies, when people cast concrete, the concrete makes contact with the auxiliary formwork bodies and compresses the auxiliary formwork bodies, accordingly, the compression springs retract, the auxiliary formwork bodies move close to the main formwork bodies, the elasticity between the main formwork bodies and the auxiliary formwork bodies can be effectively improved, and occurrence of formwork bulging is effectively reduced.
Description
technical field [0001] The invention relates to a pouring template, in particular to a pouring template for reservoir dams. Background technique [0002] Reservoir dams are water-retaining structures that intercept water flow in river channels to raise water levels or regulate flow. Reservoirs can be formed to raise water levels, regulate runoff, and concentrate water heads for flood control, water supply, irrigation, hydroelectric power generation, and improved shipping. River regulation structures that adjust the river regime and protect the bank bed are also called dams, such as spur dams, shun dams, and submerged dams. [0003] At present, when the reservoir dam is pouring concrete, the wooden formwork is generally used. When the wooden formwork is reinforced, the back corrugated is generally used, but it is difficult to reinforce the back corrugated, and the wooden formwork is easy to expand during the pouring process, which affects the pouring effect . Therefore, we...
