specific Embodiment approach 1

[0014] Specific implementation mode one: the preparation method of the anti-seepage water delivery tank of the channel in this implementation mode is implemented according to the following steps:

[0015] 1. Weigh 390-420kg of cement, 70-80kg of fly ash, 25-30kg of mineral powder, 178-198kg of water, 600-720kg of medium sand, 677-718kg of gravel with specifications 1-2, 400-450kg of crushed stone with a specification of 0.5, 5-8kg of steel fiber and 9.5-10.5kg of admixture are used as raw materials;

[0016] 2. Add the weighed raw materials to the mixer, stir them evenly, and then transfer them to the distribution machine through the feeding truck. In the water tank mould, at the same time, the vibrating table drives the anti-seepage water delivery tank mold to vibrate at a frequency of 1000-1500 Hz for 2-3 minutes to complete the cloth vibration molding of concrete raw materials;

[0017] 3. Transport the mold of the anti-seepage water delivery tank carrying the vibration-fo...

specific Embodiment approach 2

[0021] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the label of the cement described in step one is 425. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0022] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the grade of the fly ash described in step 1 is the first grade. Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention provides a preparation method of an anti-seepage delivery water of a channel, relates to the preparation method of a U-shaped / rectangular water tank for water delivery in irrigation and water conservancy, and is used for solving the problems of rough surface, poor freezing resistance and poor durability of a U-shaped tank and a trapezoid tank which are obtained by the existing preparation method. The preparation method provided by the invention comprises the following steps: 1, preparing raw materials; 2, evenly stirring the raw materials in a stirrer and then pouring into a mould; vibrating the mould of the anti-seepage water delivery tank on a suspension-type vibration platform for finishing the material distribution vibration moulding of the concrete raw materials; 3, transporting the mould carried with a concrete water tank into a curing kiln for steam curing and then transferring the mould from the curing kiln; and 4, demoulding the anti-seepage water delivery tank, thus finishing the preparation of the anti-seepage water delivery tank of a channel. According to the method, the overall vibration treatment of the concrete raw materials in the mould is carried out by adopting the vibration platform, so that the concrete has the advantages of uniform quality, smooth surface and good structural mechanical property and the concrete parameter of the concrete can reach a C50F300 level.

Description

technical field [0001] The invention relates to a preparation method of a U (rectangular) water tank used for farmland water conservancy water delivery. Background technique [0002] With 6% of the world's fresh water resources and 9% of the arable land, China has solved the problem of feeding 21% of the world's population, and farmland water conservancy has played a vital role. [0003] In recent years, the central government has insisted on taking the construction of farmland water conservancy as an important basis for ensuring the stable development of agriculture and national food security, continuously improving the policy support system, and intensifying various efforts to promote farmland water conservancy into a new stage of development. In 2012, the "Water Conservation and Grain Increase Action" was launched in the four northeastern provinces and regions, but the "last mile" from the branch canal to the field is the weakest link in farmland water conservancy, and th...
