Problems solved by technology

The river improvement structures that adjust the river regime and protect the bank bed are also called dams, such as spur dams, shun dams, and submerged dams. Due to the huge construction projects of dams, most of them are built with local materials, and the water seepage and leakage caused by dams are bothering people. A big problem. At present, the anti-seepage structure is widely used to prevent leakage by blocking, but it is still unable to effectively prevent the leakage of the dam body.

Embodiment 1

[0023] A method for preventing seepage and sealing water in hydraulic engineering, comprising the following steps:

[0024] Step 1. After the main structure of the dam body of the water conservancy project is solidified, use an excavator to excavate a 0.5-meter-deep and 0.5-meter-wide gully at the bottom one meter inside the dam body, and level the soil in the gully to make the whole gully regular;

[0025] Step 2: Cover the inner surface of the dam body with a layer of stainless steel wire mesh with a diameter of 3mm, fix the wire mesh on the inner surface of the dam body with rivets, then make a concrete formwork, and fix the concrete formwork on the top of the stainless steel wire mesh, The distance between the concrete formwork and the stainless steel wire mesh is 10cm;

[0026] Step 3, select the time period when the temperature is lower than 25 degrees Celsius to make concrete, select cement and quicklime powder with low heat of hydration as raw materials, and add anti-s...

Abstract

The invention discloses a water conservancy project anti-seepage method, specifically relates to the technical field of water conservancy construction, comprising the following steps: step 1, after the main structure of the dam body of the water conservancy project is solidified, an excavator is used to dig a dam body at the inner bottom of the dam body A 0.5-meter-deep and 0.5-meter-wide gully was excavated at a distance of 1.5 meters, and the soil in the gully was leveled to make the whole gully regular. The present invention sets a multi-layer waterproof structure. After the dam body completes water storage, the stainless steel wire mesh on the surface of the asphalt will be slowly embedded into the interior of the asphalt layer under the influence of water gravity. At this time, the two-layer composite geomembrane The asphalt is always kept in a solid state, and the bottom of the dam body is excavated and filled with concrete, and steel bars are used to fix the upper layer of stainless steel wire mesh and composite geomembrane to make the entire anti-seepage structure more stable. It is fastened and not easy to fall off, making the anti-seepage and water-proof more thorough.

Description

technical field [0001] The invention relates to the technical field of water conservancy project construction, and more specifically, the invention relates to a method for preventing seepage and water in a water conservancy project. 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. [0003] A dam is a water-retaining structure that intercepts the water flow of a river channel to raise the water level or regulate the flow. Reservoirs can be formed to raise water levels, ...
