AI Technical Summary
Technical Problem
Existing drainage channel construction methods result in poor structural stability, are prone to cracking or damage due to soil deformation, and have high construction costs.
Method used
The first support layer is formed by U-shaped concrete platforms and gabions filled with crushed stones, combined with the second support layer of concrete layer, and anchor rods and waterproof geotextiles are used to enhance the structural stability and waterproofing ability.
Benefits of technology
While ensuring structural stability, it reduces construction costs, absorbs soil deformation, avoids cracking of the concrete layer, and improves the overall stability and waterproof performance of the drainage channel.

Abstract
The invention provides a drainage channel structure of a geological disaster control project and a construction method of the drainage channel structure, and relates to the technical field of drainage channels. The drainage channel structure of the geological disaster control project comprises an excavated U-shaped drainage channel body, a channel body supporting structure is arranged in the drainage channel body, and the channel body supporting structure comprises a first supporting layer and a second supporting layer arranged on the inner side of the first supporting layer; the first supporting layer comprises U-shaped supporting walls and a U-shaped concrete platform which are matched with the U-shaped drainage channel body, the U-shaped supporting walls are embedded in supporting wall setting cavities so as to form the first supporting layer with the U-shaped concrete platform, and the U-shaped supporting walls are formed by filling stone cages with broken stones; the second supporting layer is a concrete layer, and waterproof geotechnical cloth is arranged between the second supporting layer and the first supporting layer. The concrete layer of the second layer is not prone to cracking or damage, the canal body supporting structure is more stable, and the service life is longer.
