Problems solved by technology

[0002] The canals commonly used in rural areas are all impermeable reinforced concrete channel slabs. The mortar pointing joints between the channel slabs are sealed to form a completely sealed water storage system in the channel slab space, so that the water and soil are separated, and the water is isolated from the surrounding environment. , can not give full play to the role of water
At the same time, the foundation of the channel is poor, and it is easy to form an undercurrent, resulting in a serious waste of water resources

specific Embodiment

[0034] Example: A construction method for a water channel with a depth of 3m and a width of 4m, such as figure 1 shown, including the following steps:

[0035] Step 1. Groove according to the design width and depth of the channel to form a 3×4m foundation pit;

[0036]Step 2. Lay two 20cm thick lime soil layers 2 on the bottom of the foundation pit and spread and compact them, then spread 1.5m high lime soil layers 2 to both sides of the foundation pit and compact them. Containing 4wt% clay, the clay adopts clay with relatively uniform particles and small particle size;

[0037] After step 3 and step 2 are completed, the foundation pit is shaped, and then a layer of 5 cm thick mud is covered on the lime soil layer to form a mud layer 3;

[0038] After step 4 and step 3 are completed, do a good job of waterproofing the foundation pit until the mud layer 3 is air-dried;

[0039] Step 5, after the mud layer is air-dried, start to install the channel side plate 4 and the channe...

Abstract

The invention discloses a water channel structure, comprising a water channel body, the bottom of the water channel body is a lime soil layer, a layer of mud layer is covered on the surface of the bottom of the water channel body, the mud layer is flatly laid on the lime soil layer, and the two sides of the water channel body are respectively fixed The channel side plate is installed, the channel side plate is a hollow box-shaped structure, the top of the channel side plate has a hollow structure, and a plurality of through holes are dug on the side of the channel side plate, and the side of the channel side plate away from the channel body is backfilled The soil forms a backfill soil layer, and on the mud layer, a channel bottom plate is fixedly installed between two opposite channel side plates, and the channel bottom plate is a hollow box-shaped structure. By relying on the lime soil layer and the mud layer to form a closed water storage space, the channel side plate and the channel bottom plate only play the role of skeleton, forming an environmentally friendly channel that does not separate water and soil. It can not only play the function of general channel water transportation, but also efficiently To store water resources, it has the function of a certain small reservoir.

Description

technical field [0001] The invention relates to the field of farmland water conservancy, in particular to a canal structure and a construction method thereof. Background technique [0002] The canals commonly used in rural areas are all impermeable reinforced concrete channel slabs. The mortar pointing joints between the channel slabs are sealed to form a completely sealed water storage system in the space of the channel slabs, so that the water and soil are separated, and the water is isolated from the surrounding environment. , can not give full play to the role of water. At the same time, the foundation of the channel is poor, and it is easy to form an undercurrent, resulting in a serious waste of water resources. Contents of the invention [0003] The purpose of the present invention is to: aim at the above problems, to provide a canal structure and its construction method, by relying on the lime soil layer and the mud layer to form a closed water storage space, the c...
