Embodiment Construction

[0050] Examples see Figure 1 ~ Figure 2 As shown, a kind of anti-corrosion encased concrete cast-in-situ pile applied on saline soil foundation comprises a concrete pile body 14, a steel cage 3 is arranged in the concrete pile body 14, and a flexible rubber cage is wrapped on the bottom and the periphery of the concrete pile body 14 Water-proof anti-corrosion protection cylinder 2.

[0051] The water-proof and anti-corrosion protection tube 2 is formed by hot pressing or welding n-1 layers of geomembrane sandwiched by n layers of polyethylene geotextile bags, n≥2. The geomembrane is polypropylene geomembrane or composite geomembrane. Polyethylene geotextile bags can be filament woven high-strength geotextile bags, woven geotechnical anti-seepage bags, woven geotechnical composite bags or woven geotextiles. It can be two cloth clips and one film.

[0052] see Figure 3 ~ Figure 13 As shown, the construction steps of the above-mentioned anti-corrosion encased concrete cast-...

Abstract

The invention relates to an anti-corrosion inclusion bored concrete pile used for saline soil foundations and a construction method thereof. The bored concrete pile comprises a concrete pile body in structure, wherein the inside of the concrete pile body is provided with a reinforcement cage, a flexible, watertight and anticorrosive protection tube is covered on the bottom and periphery of the concrete pile body; and the watertight and anticorrosive protection tube is formed by hot-pressing or welding n layers of polyethylene geotextile bags and n-1 layers of geomembranes, and n is not less than 2. The construction method comprises the following steps: injecting cement mortar between pile holes and the watertight and anticorrosive protection tube, then injecting water in the watertight and anticorrosive protection tube to ensure that the watertight and anticorrosive protection tube expands to the pile hole wall, then injecting concrete paste in the watertight and anticorrosive protection tube, discharging water from the watertight and anticorrosive protection tube by using the concrete paste, and obtaining the bored concrete pile when concrete is set. The invention solves the anticorrosive problem of the concrete pile in saline soil areas, effectively reduces the production cost of the anti-corrosion bored concrete pile and satisfies the strength requirements of projects. The anti-corrosion inclusion bored concrete pile of the invention is applicable to the concrete pile construction with anticorrosive requirements and is especially used in saline soil foundations.

Description

Technical field [0001] The invention involves a concrete irrigation pile and its construction method. Background technique [0002] The anti -corrosion problem of steel structures and concrete in salted soil areas has always been the research and development goals of construction personnel. Steel and concrete are currently the main body of various important buildings.The naked structure can be used to achieve anticorrosion by regularly painting various anti -corrosion materials methods, and the anti -corrosion of underground engineering is more difficult.Because the components are directly contacted with strong corrosive salt soil and brine and cannot be scratched regularly, the corrosion materials cannot be applied regularly, so people in the actual engineering use the following two methods for anti -corrosion treatment: [0003] (1) Concrete piles wrapped in thick wall steel pipes and protective concrete. The thickness of the wall is generally ≥10㎜.Generally, the pile length is...
