Water retaining dam fixing formwork for water conservancy project and construction method thereof

Abstract

The invention discloses a water retaining dam fixing formwork for a water conservancy project and a construction method thereof, and relates to the technical field of the water conservancy projects. The fixing formwork comprises a dam base layer and a gravel block filling frame, the sides, which penetrate through and extend out of a second side form baffle plate, of split bolts are in threaded connection with fixed nuts, and a filling baffle frame is fixedly connected between a first side form baffle plate and the second side form baffle plate; and a gravel block and clay mixture fills the portions among the filling baffle frame, the gravel block and clay mixture and the filling baffle frame are mixed to form a filling gravel block layer, the filling gravel block layer and concrete anti-permeation blocks form a water retaining dam inner base layer. According to the water retaining dam fixing formwork for the water conservancy project and the construction method thereof, the partitioning construction is achieved, so that the construction difficulty is reduced, the construction time is shortened, meanwhile, the toughness of the water retaining dam is increased, and the service life of the water retaining dam is prolonged; and constant-gradient water discharging is achieved during flood releasing and water discharging, so that the purpose of stably releasing the pressure during flood control of the water retaining dam is achieved.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a retaining dam fixed formwork for water conservancy engineering and a construction method thereof. Background technique [0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and rejuvenating profits. Also known as water engineering. Water is an indispensable precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's life and production for water resources. Water conservancy projects need to build different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, canals, rafts, and fishways to achieve their goals.

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a retaining dam fixed formwork for water conservancy projects and its construction method, which solves the problem that the current dam construction adopts integrated construction and one-time construction of the dam, which is difficult and time-consuming. In addition, the dam generated by the overall construction may collapse when the flood occurs. The overall retaining dam is also susceptible to cracking due to the influence of temperature and external environment, and the safety performance of flood control and earthquake resistance is poor.
