Embodiment 1

[0057] The construction site is flat land, and the soil at the construction site is naturally dry or slightly moist cohesive soil or silty cohesive soil. It is necessary to build a new channel 7 with a rectangular cross section. The height of the section of the concrete wall 8 of the new channel 7 is 1.3m. The thickness is 0.4m, the section of the excavation surface 1 is rectangular, the height is 1.3m, and the width is 1m. The specific steps are as follows:

[0058] Step 1. Determine the construction location, drain or intercept the water at the construction location at least one week in advance, and create conditions for the construction;

[0059] Step 2. Renovate the construction access road to meet the passage of small transport machinery. After cleaning the construction site, carry out axis stakeout, so as to facilitate construction according to the only standard during excavation;

[0060] Step 3: Carry out earthwork excavation according to the size of the section of the...

Embodiment 2

[0065] The construction site has the original channel, and the size of the original channel is larger than the new channel 7. There are many crushed stones with a particle size larger than 15cm at the bottom of the original channel. The soil at the construction site is naturally dry or slightly moist clay or silty clay. A new channel 7 with an inverted isosceles trapezoidal section is built. The concrete wall 8 of the new channel 7 has a right-angled trapezoidal section, a height of 1.3m, a thickness of the upper bottom of 0.2m, and a thickness of the lower bottom of 0.4m. The section is rectangular, with a height of 1.3m and a width of 1.4m. The specific steps are as follows:

[0066] Step 1. Determine the construction location, drain or intercept the water at the construction location at least one week in advance, and create conditions for the construction;

[0067] Step 2. Renovate the construction access road to meet the passage of small transport machinery. Clean up the c...

Embodiment 3

[0073] The construction site has the original channel, and the size of the original channel is smaller than the new channel 7. There are many gravels with a particle size greater than 15cm at the bottom of the original channel. The soil at the construction site is naturally dry or slightly moist clay or silty clay. A new channel 7 with an inverted isosceles trapezoidal section is built. The concrete wall 8 of the new channel 7 has a right-angled trapezoidal section, a height of 1.1m, a thickness of the upper bottom of 0.2m, and a thickness of the lower bottom of 0.5m. The section is rectangular, with a height of 1.1m and a width of 1.6m. The specific steps are as follows:

[0074] Step 1. Determine the construction location, drain or intercept the water at the construction location at least one week in advance, and create conditions for the construction;

[0075] Step 2. Renovate the construction access road to meet the passage of small transport machinery, clean the surface o...

Abstract

The invention relates to an irrigation and water conservancy construction method. The irrigation and water conservancy construction method comprises the following specific steps that a construction position is determined, and drainage or interception treatment is conducted on the construction position; a construction road is repaired, and after surface cleaning and impurity cleaning are conducted on the construction position, construction lofting is conducted; if the original channel exists in the construction position, when the size of the original channel is larger than or equal to that of the new channel, backfilling and compacting are conducted in the original channel, and then earthwork excavation is conducted; when the size of the original channel is smaller than that of the new channel, earth excavation is conducted on the original channel; if the original channel does not exist at the construction position, earth excavation is conducted according to the size of the new channel; after excavation is completed, environment-friendly spraying films are sprayed to the two sides of the excavation face, and concrete pouring is conducted on the bottom of the excavation face; after concrete at the bottom of the excavation face is solidified, formworks are installed on the two sides of the excavation face, and concrete pouring is conducted in gaps between the excavation face and the formworks; and after the concrete is solidified, the formworks are dismantled, and then maintenance is conducted. The method is convenient to construct, and has the advantages of shortening the construction period and saving the cost.

Description

technical field [0001] The invention relates to a construction method, more specifically, it relates to a farmland water conservancy construction method. Background technique [0002] In recent years, my country has deepened reforms and vigorously advocated innovation. In terms of agriculture, my country's basic farmland, high-standard farmland and irrigation area renovation projects have also undergone nearly 20 years of construction and development. However, the current farmland construction and irrigation area renovation only focus on The construction quality of the farmland or irrigation area after the construction is completed, while the construction industry and construction progress are often ignored. When the farmland and irrigation area itself have achieved good results, the construction period is still long, the construction cost is high, and the personnel The large quantity demand and high labor intensity are the bottlenecks restricting the development of high-stand...
