Man-made bamboo raft cofferdam and construction method thereof

Abstract

The invention belongs to the field of man-made bamboo raft cofferdams, and particularly relates to a man-made bamboo raft cofferdam and a construction method thereof. The man-made bamboo raft cofferdam is divided into an upper bamboo raft cofferdam layer and a lower bamboo raft cofferdam layer. The lower bamboo raft cofferdam layer comprises two rows of lower-layer bamboo rafts, and the lower-layer bamboo rafts comprise lower-layer bamboo and iron wires used for tightly twisting the lower-layer bamboo. The length of the portion, located in soil, of the lower-layer bamboo is not smaller than that of the portion, exposed out of the soil, of the lower-layer bamboo. The lower bamboo raft cofferdam layer is constructed between the two rows of the lower-layer bamboo rafts. The upper bamboo raft cofferdam layer comprises two rows of upper-layer bamboo rafts. Upper-layer bamboo of the upper-layer bamboo rafts is vertically driven into the lower bamboo raft cofferdam layer. According to the man-made bamboo raft cofferdam and the construction method thereof, the cofferdam can be reinforced with the bamboo rafts, the strength requirement and the height requirement of the cofferdam can be met, the effect that the cofferdam does not collapse is guaranteed, and meanwhile the sufficient blow-fill capacity can be ensured.

Description

technical field [0001] The invention belongs to the field of artificial bamboo raft cofferdams, in particular to an artificial bamboo raft cofferdam and a construction method thereof. Background technique [0002] At present, in some projects of our company, cofferdams need to be built, and at the same time, in some cases, cofferdams need to be built through fish ponds. However, the average water depth of the fish pond is 1 meter, and the mud at the bottom is silt, so excavators cannot work. In addition, the rainy season in Bangladesh is coming early, the fish pond drainage and sediment drying effect are not good, and artificial construction is difficult. [0003] Therefore, based on these problems, an artificial bamboo raft cofferdam and an artificial bamboo raft cofferdam with sufficient filling capacity are provided to ensure that the cofferdam meets the strength and height requirements by reinforcing the cofferdam with bamboo rafts, which not only ensures that the coffe...
