Channel seepage-guiding and non-return system

Abstract

The invention provides a channel seepage-guiding and non-return system, which comprises a longitudinal and transverse gridding draining body and a seepage-guiding and non-return device, wherein the longitudinal and transverse gridding draining body is arranged under the concrete seepage-proof panel of channel revetment; the grids of the longitudinal and transverse gridding draining body are filled with sand filter materials; the lower end of the longitudinal and transverse gridding draining body is connected with the seepage-guiding and non-return device; the seepage-guiding and non-return device is arranged in the groove of the bottom plate of the channel and is provided with a concrete shell; and the top of the seepage-guiding and non-return device is level with the bottom of the channel. The channel seepage-guiding and non-return system can guide and permeate the ground water to the channel, thereby reducing ground water level, increasing the stability of side slopes, preventing the seeping water from causing uplift damage to the bottom plate and the revetment of the channel, and frost boil in winter, enhancing the stability of the channel, and prolonging the service life. The channel seepage-guiding and non-return system also can prevent water in the channel from seeping and effectively increase the utilization factor of the water in the channel while guiding the ground water to the channel quickly.

Description

technical field [0001] The invention belongs to the technical field of agricultural water and soil engineering, and in particular relates to a channel seepage guide and anti-reverse system for concrete channels. Background technique [0002] At present, the concrete anti-seepage channel has been widely used because of its good anti-seepage and anti-shock performance, strong durability and wide applicability. However, under the condition of high groundwater level in the irrigation area, when the groundwater level is higher than the water level in the canal, it is very easy to cause damage to the canal floor and slope protection under the support of seepage water. In winter, the water content of the canal bed is relatively high, and frost heave damage to the canal floor and slope protection is particularly prone to occur. Sometimes, even if the initial groundwater level in the irrigation area is not very high, the continuous recharge of seepage water during the long-term wate...
