Embodiment Construction
[0049] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0050] Such as figure 1 As shown, the present invention provides a high-standard farmland canal structure, including an excavation groove 1 and a bottom cushion 31, the contour line 11 (side wall) of the excavation groove 1 is located at the outermost periphery of the entire canal structure, and the bottom cushion 31 Located at the bottom of the excavation trench 1, it is mainly used to support the structure for passing water on the channel such as the side slope 4. The bottom cushion layer 31 is installed with the side slope 4 at both ends, and the excavation trench 1 is excavated by earthwork before the construction of the channel , the structure between the side slope 4 and the contour line 11 (side wall) of the excavation trench 1 is the backfill soil layer 2, and the side slope 4 can be a dam formed by pouring concrete, or a dam formed by compacting soil...

The invention relates to a high-standard farmland channel construction method and structure, and relates to the technical field of irrigation channels. The high-standard farmland channel constructionmethod comprises the steps of vegetation cleaning, earth excavation, arrangement of a side slope and a bottom cushion layer, arrangement of a yellow sand layer, a gravel layer and a mortar layer, arrangement of steel formworks and a formwork adjustment device, concrete pouring, steel formwork dismantling, arrangement of drainage pipes, and earthwork backfilling, wherein the arrangement of the steel formworks and the formwork adjustment device comprises the following steps of: firstly, arranging the steel formworks on the two sides of a channel, placing the steel formworks on the cement mortarlayer, and then fixing the bottom of the formwork adjustment device to a concrete bottom plate, and adjusting the positions of the steel formworks by the formwork adjustment device, so that a concretepouring cavity with the thickness of 3cm to 5cm is formed between each steel formwork and the cement mortar layer. The high-standard farmland channel construction method has the advantages of stablestructure and relatively long service life.
Description
technical field [0001] The invention relates to the technical field of irrigation canals, in particular to a construction method and structure of high-standard farmland canals. Background technique [0002] my country is a country with a serious shortage of water resources, but the waste of agricultural irrigation water is very serious. Due to the low standard of farmland water conservancy facilities, unsuitable, aging, outdated irrigation methods and poor management, the effective utilization rate of agricultural irrigation water in the country is only about 40%, which is only half of that of developed countries. [0003] A Chinese patent with publication number CN109723043A has now been retrieved, which discloses a construction method for irrigation and drainage channels. The method includes the following steps: measuring and setting out lines, and using the plane control points and benchmark points provided on site as the center of the construction pile and the elevation ...
