The invention discloses a construction method for conveying concrete under a gentle slope and an abrupt slope and a mist articulated chute device. 3-60 segments of 6-m-long straight pipes are connected through flanges to form an articulated chute. An axial flow fan is installed on the first segment of straight pipe at the top end of the articulated chute. A mist generator is installed on each segment of straight pipe. The upper end of the first segment of straight pipe at the top end of the articulated chute is connected with a bent pipe through a flange. A hopper discharge outlet is connected with a downward straight articulated chute which is inserted into the bent pipe. A hopper is erected on a hopper support provided with a water tank. A water pipe is led out from the water tank and connected with the mist generators one by one. The last segment of straight pipe at the tail end of the articulated chute is connected with one end of a discharge pipe through a flange. A lifting lug is weld to an outer layer steel pipe of the discharge pipe. The discharge pipe is sleeved with a cloth sleeve. According to the construction method for conveying the concrete under the gentle slope and the abrupt slope and the mist articulated chute device, equipment investment is few, operation cost is low, project investment is reduced, durability is achieved, the failure rate is low, and the construction period is shortened.
Description
technical field [0001] The invention belongs to the field of building construction, and relates to a construction method and a mist slide pipe device for conveying concrete under gentle slopes and steep slopes. In particular, it involves the pouring of foundations, floor concrete, and low concrete structures such as box culverts, channels, inverted siphons, and water pipelines in field operations such as water conservancy, electric power, mining, and agricultural and forestry irrigation. Low equipment investment, low operating costs, saving engineering investment, durable, low failure rate, saving construction period. Background technique [0002] At present, when pouring concrete for foundations and structures under large slopes in construction industries such as water conservancy, electric power, and mining, it is impossible to directly build roads (or the cost is very high) to the pouring site due to too large slopes (required for slope stability), and the water conservan...
