Water conservancy construction waterproof structure

Abstract

The invention discloses a water conservancy construction waterproof structure. The waterproof structure comprises a waterproof film arranged at an underground trench, the waterproof film is located between a road and a diversion canal and used for conducting isolation and waterproofing on water overflowing from underground soil between the road and the diversion canal, and the waterproof film is composed of an upper section film and a lower section film; and breathable drainage pieces are arranged among multiple bent positions of the upper section film and used for draining water overflowing from soil, close to one side of road, of the waterproof film in drainage mode. According to the water conservancy construction waterproof structure, the waterproof isolation area of the waterproof film is increased, and the effective waterproof effect on the road and the diversion canal is achieved; meanwhile, the breathable drainage pieces are arranged at the multiple bent positions of the upper-section film, so that water and gas overflowing from soil on the side, close to the road, of the waterproof film are drained and discharged, the problem that soil at the bottom end of the roadbed of the road is unstable due to the fact that more water is contained in the soil at the bottom end of the roadbed of the road is effectively solved, and the safety performance of the road is improved.

Description

technical field [0001] The invention relates to the technical field of water conservancy construction, in particular to a waterproof structure for water conservancy construction. 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. [0003] Water conservancy engineering is one o...

Problems solved by technology

[0005] In this patent application, a waterproof membrane is set between the canal and the road to achieve a good waterproof effect on the aqueduct, but the waterproof membrane is set between the canal and the road, and while waterproofing the two, it also causes The water at the subgrade of the road cannot penetrate well, and the impermeable water will cause the soil under the subgrade to be very unstable and affect the safe use of the road; at the same time, although waterproof materials, namely waterproof membranes are installed for waterproofing, the waterproof performance of the waterproof membrane not only depends on Due to the characteristics of waterproof materials, it is also affected by the state of the bottom layer and the external environment. For example, the water content of the bottom layer is high, and the vapor pressure of the waterproof membrane after construction and the production pressure between the low pressure will cause the soil at the waterproof material to be affected. The waterproof membrane is cracked or damaged due to the impact of the impact. For this reason, we propose a waterproof structure for water conservancy construction
