Problems solved by technology

Since the dam body to be reinforced is used to seal the underground reservoir, if the structure of the dam body to be reinforced is removed, problems such as preventing the water outflow of the underground reservoir and the instability of the artificial dam body must be considered, resulting in extremely difficult construction

Abstract

The invention discloses a reinforced dam body structure and a construction method thereof, comprising a roadway, a dam body to be reinforced in the roadway, and a reinforced dam body in the roadway for reinforcing the dam body to be reinforced; The reinforced dam body includes a dam body body, a dam body top plate, a dam body bottom plate and a dam body side plate; the dam body body is connected to the dam body to be reinforced. The reinforced dam body structure and the construction method thereof disclosed by the invention can provide reinforcement for the dam body to be reinforced by pouring the reinforced dam body on one side of the dam body to be reinforced, thereby effectively repairing and strengthening the original coal mine underground reservoir.

Description

technical field [0001] The invention relates to the intersecting fields of mining engineering and water conservancy engineering, in particular to a reinforced dam structure and a construction method thereof. Background technique [0002] At present, the construction of retaining dams for distributed underground reservoirs in coal mines is still being further studied and designed. The construction of sluice gates and sluice walls is regulated in the "Coal Mine Safety Regulations" and "Coal Mine Water Prevention and Control Regulations", which are mainly based on the perspective of water prevention and control, without considering the long-term role of underground reservoir water storage; The construction of the dam body has been regulated in detail, but the construction of the dam body of the surface reservoir and the construction of the retaining dam of the underground reservoir are obviously different. [0003] Comparing the dam body of the underground reservoir of the coa...
