Reinforced and reconstructed dam and dam reinforcing and reconstructing method

Abstract

The invention relates to a reinforced and reconstructed dam which comprises a new overflow plane, a new dam top, a new waterward plane, a buffer end, and a new energy dissipation and erosion control section which are connected in sequence; the new dam top is used for replacing an original dam top; the new overflow plane comprises an overflow plane, an anchor bar, a steel wire mesh and concrete; the new waterward plane comprises a waterward plane, an anchor bar, a steel wire mesh and concrete; the new energy dissipation and erosion control section comprises an energy dissipation and erosion control section, an anchor bar, a steel wire mesh and concrete. The dam reinforcing and reconstructing method comprises the following steps: (1) a dam top is dismounted from AB elevation to CD elevation;and then concrete is poured to the CD elevation till reaching the AB elevation; (2) roughening the surfaces of the waterward plane, the overflow plane and the energy dissipation and erosion control section, implanting the anchor bars, and externally hanging the steel wire meshes at the outer ends of the anchor bars; (3) pouring concrete to the surfaces of the waterward plane, the overflow plane and the energy dissipation and erosion control section, the anchor bars and the steel wire meshes, and pouring in precast concrete short columns, so as to form the new waterward plane, the new overflowplane and the new energy dissipation and erosion control section. The reinforced and reconstructed dam has the advantages of being firm in reinforced dam and bringing convenience for self rescue of the drowning. The invention belongs to the technical field of dams.

Description

Technical field [0001] The invention belongs to the technical field of waterfronts, and in particular relates to a reinforced and reconstructed waterfront and a waterfront reinforcement and reconstruction method. Background technique [0002] The main function of water is to raise the water level of the river, for irrigation, river water intake, power generation, water storage and beautiful scenery. After a long period of operation of the waterfront, the main problems that generally occur are: leakage, cracks and damages in the back body, damage to downstream energy dissipation and anti-scouring facilities, etc., which affect the use function and even endanger the safety of the waterfront. At present, for the long-running waterfront, you can choose to demolish and rebuild, but it costs a lot of money; or simple repair, but the repaired waterfront is not stable enough, and when the water volume is too large, it is easy to cause the waterfront to collapse and other problems.

Problems solved by technology

After a long period of operation of the water pit, the main problems generally appear are: leakage, cracks in the pit body, damage to downstream energy dissipation and anti-scouring facilities, etc., which affect the use function and even endanger the safety of the water pit

At present, for the long-term operation of the water pit, you can choose to demolish and rebuild it, but it costs a lot of money; or simply repair it, but the repaired water pit is not stable enough, and when the water volume is too large, it is easy to cause problems such as the water pit being washed away.

Moreover, the existing water pit is not provided with a structure for those who fall into the water to climb, so it is not conducive to the self-rescue of those who fall into the water.
