[0032] Example

[0033] Such as figure 1 , 2 As shown in 3, the anti-seepage ecological slope protection method of the irrigation water delivery channel is to reserve a certain specification and number of rectangular holes when constructing the concrete irrigation water delivery channel (1), or to irrigate the already constructed concrete lining. A certain specification and number of rectangular parallelepiped holes are excavated in the water channel (1). The water delivery channel can be a U-shaped section, a trapezoidal section, a rectangular section or a compound section. The present invention takes the common U-shaped section and trapezoidal section as examples for illustration , The length, width and depth of the holes are 30cm*20cm*30cm; the holes are distributed on the wall and bottom of the channel in a staggered manner. The present invention takes as an example the distance between the parallel holes is 50cm and the distance between two rows of holes is 40cm ( The densi...

Abstract

The invention provides an anti-seepage type assembly type ecological slope protection method for an irrigation water conveying canal. The anti-seepage type assembly type ecological slope protection method includes the following steps that (1) when the concrete irrigation water conveying canal (1), or a U-shaped fracture surface, or a trapezoid-shaped fracture surface, or a rectangular fracture surface or a compound fracture surface is built, a cuboid hole groove is reserved; (2) anti-seepage type ecological boxes (2) which are cultured in a garden house and with healthily growing plants are transferred to the cuboid hole groove in batches; (3) the lower portions of edges of the peripheries of the upper surfaces of the ecological boxes are each provided with a circle of rubber anti-seepage spacers (10) in a cushioned mode; (4) expansion anchor bolts (8) are arranged in the hole drilled in the step (1), and screw caps (9) are tightly screwed to fix the anchor bolts (8). The anti-seepage type assembly type ecological slope protection method has the advantages that the irrigation water utilization rate can be increased without affecting the safety of a slope protection structure, and overall collapse of the canal is avoided; a habitat can be provided for aquatic animals; aquatic plants are made to cover slope protection concrete to the maximum degree to form a green corridor, and the self cleaning capacity of the canal is improved; an original irrigation water conveying canal is fully utilized, and the anti-seepage and slope protection purposes are achieved.

Description

technical field [0001] The invention relates to an anti-seepage assembly type ecological slope protection method for irrigation water delivery channels, which belongs to the technical field of irrigation water delivery channel seepage prevention and ecological function combination, and is suitable for traditional irrigation water delivery channels with deteriorating habitat conditions and water resources Seepage-proof ecological slope protection for rare semi-arid and arid irrigation channels. Background technique [0002] my country is a country seriously short of water resources, and the utilization rate of water resources is also very low. One of the important reasons is the waste of agricultural irrigation water in our country. According to statistics, the water diversion for irrigation of paddy fields and dry land in my country is 344.5 billion m 3 However, due to the low standards of farmland water conservancy facilities, aging, unsuitable facilities, and backward irr...
