Problems solved by technology
Since the drainage well is located at the tail of the tailings pond and is in the water, it is impossible to lift and install the fasteners with the help of electrical equipment
The arch slab is transported to the side of the drainage well by ship. After the boat is fixed, the arch slab is manually transported to the derrick and raised with cement. Because the ship is unstable on the water surface and the arch slab is heavy with cement components, the center of gravity of people moving heavy objects on the ship is not right. Stable, a little carelessness can easily cause accidents such as bruises and drowning, the labor intensity is high, and the safety factor is low
Especially in the flood season, in order to ensure safety, the arch slab of the drainage well during the flood season should not exceed 1 square above the water surface, about 25cm, and it needs to be piled up once every 3-5 days, and the operation is frequent

Embodiment Construction
[0023] The present invention can be explained in more detail by the following examples, and the purpose of disclosing the present invention is intended to protect all changes and improvements within the scope of the present invention, and the present invention is not limited to the following examples;
[0024] A tailings pond drainage shaft arch plate installation method described in conjunction with the accompanying drawings includes the following steps:
[0025] 1) Firstly, construct the well base 1 of the drainage well, and set 6 vertical columns 2 symmetrically on the well base 1, and the well base 1 and the vertical columns 2 are both reinforced concrete structures;
[0026] 2) Set up a layer of ring beam 3 every 2-3 meters on the column 2, and the column 2 divides the ring beam 3 into 6 parts, and each of the 6 parts is provided with a hanging ring 6 in the middle.
[0027] 3) After the drainage well frame is completed, the prefabricated arch plate 5, the inner and outer...

Because the drainage well is located at the tail of the tailings pond and is in the water, it is impossible to lift and install the fasteners with the help of electrical equipment. The arch slab is transported to the side of the drainage well by ship. After the boat is fixed, the arch slab is manually moved to the derrick and raised with cement. Because the ship is unstable on the water surface and the arch slab is heavy with cement components, the center of gravity of the heavy objects being moved on the ship is not correct. A little carelessness can easily cause accidents such as bruises and drowning. The labor intensity is high and the safety factor is low. However, in the method for installing the arch plate of the drainage well of the tailings pond, people can directly pass the guide chain on the ship. The operation eliminates the danger and labor intensity caused by manually moving the arch on the ship.
Description
Technical field: [0001] The present application relates to the technical field of tailings pond drainage wells, in particular to a method for installing an arch plate of a tailings pond drainage well. Background technique: [0002] The tailings reservoir drainage well is an important flood control facility. When the water level of the reservoir rises rapidly in the rainy season during the flood season, the water in the reservoir overflows through the drainage well and enters the flood discharge tunnel for flood discharge to ensure the safe operation of the tailings reservoir. With the accumulation of tailings, the water level of the tailings pond continues to rise. It is necessary to increase the height of the overflow well arch to prevent the water in the pond from entering the drainage well. Because the drainage well is located at the tail of the tailings pond and is in the water, it is impossible to lift and install the fasteners with the help of electrical equipment. Th...
