Arc-surface-lap-joint self-water-stop reverse-filtering trunk

Abstract

The invention provides an arc-surface-lap-joint self-water-stop reverse-filtering trunk which comprises a water-seepage well bottom. A sleeve basket is arranged on the upper side of the water-seepagewell bottom. The peripheral side of the sleeve basket is provided with a well wall, and the well wall is formed by connecting a plurality of arc-shaped blocks through mortise and tenon joints. The peripheral side of the well wall is provided with a drain pipe. The circular well bottom is formed by splicing non-fine concrete water-permeable components, the barrel-shaped well wall is formed by combining arc-surface-lap-joint self-water-stop components through staggered joints, and the geotextile sleeve basket is arranged between the well bottom and the well wall, so that the trunk is formed withthe three parts. The trunk is arranged over the positions where piping, leaking and other dangerous cases may occur on the toe of a downstream slope of a dike or earth dam, a water burst point is effectively covered, and the piping, leaking and other dangerous cases on the downstream slope of the dike can be prevented from continuing getting worse; and through the self-water-stop well wall, the water level in the trunk is raised, the upstream seepage pressure is reduced, soil filtering-out and water draining are effectively realized, the dangerous cases are delayed, the safety of the dike isguaranteed, and meanwhile the requirements for safety and stability of the components are met.

Description

technical field [0001] The invention relates to the technical field of water-blocking and reverse-filtration wells, in particular to a self-blocking water-reverse-filtration surrounding well with lapped curved surfaces. Background technique [0002] The embankment project of the lower reaches of the Yellow River was formed in the middle of the Spring and Autumn Period. It is located at the junction of inland rivers in Henan and Shandong provinces. It is an embankment of the Shufan River built on both sides of the rivers in Henan and Shandong provinces. The current Yellow River embankment above Dongbatou in Lankao County and Ewan in Fengqiu County was built on the basis of the old embankment in Ming and Qing Dynasties, with a history of more than 500 years; It was built one after another on the basis of the Minyan, and it also has a history of more than 130 years. The length of the right bank of the Yellow River embankment is 624.248km, and the left bank of the embankment is...

AI Technical Summary

Problems solved by technology

Due to the large amount of sand and gravel materials and willow shoot materials required for sand bag filter enclosures and water basins, it is difficult to ensure that there are enough materials to meet the needs of the site. There is a problem that it cannot be quickly disposed of on the site when a dangerous situation occurs, and it is difficult to effectively Disadvantages of controlling hazards

[0011] 3. Dangerous situations such as piping and water leakage are a process of continuous development. At the beginning, only a small amount of clear water flows out. As the seepage channel continues to increase, the water volume becomes larger and turbid. The material is composed of multiple layers of sand and gravel or willow material, which is easy to fail due to the blockage of soil particles. It cannot be repaired and replaced conveniently and quickly, nor can it ensure that the drainage body is always safe and effective. In any case Disadvantages of free drainage of all seepage water

[0012] 4. Since the sand bag reverse filter enclosure is a one-time rescue equipment, there are shortcomings that it cannot be reused multiple times, and it can be selected and combined according to size, function and filter material to meet different needs.
