Example Embodiment

[0039] like figure 1 As shown, the prefabricated pile foundation anticorrosion coating of the present invention comprises a pile basic body 1, which is coated with an anticorrosion base layer 2 on the pile base body 1, and a polyurea elastic anticorrosion layer 3 is sprayed on the anticorrosion base layer 2, and the polyurea elastic anticorrosion layer The anticorrosion layer 3 is covered with a protective layer 4 of polymer reinforced mortar.

[0040] The construction process of the present invention is as follows:

[0041] Anti-corrosion material preparation and entry → anti-corrosion layer base treatment → primer construction → spraying polyurea anti-corrosion coating → spraying acceptance → protective layer construction → pile sinking construction.

[0042] Specific operation process:

[0043] 1. Material preparation and entry

[0044] 1. The finished products entering the site must be inspected and recorded according to the regulations. They can be used only after they...

Abstract

The invention relates to an anticorrosion coating of a precast pile foundation for the silt soil complicated geology. The anticorrosion coating comprises a pile foundation body, the pile foundation body is coated with an anticorrosion base layer, a polyurea elastic anticorrosion layer is sprayed on the anticorrosion base layer, and the polyurea elastic anticorrosion layer is covered with a polymer reinforced mortar protection layer. The thickness of the polyurea elastic anticorrosion layer ranges from 0.9 mm to 2.5 mm. A flexible anticorrosion layer is formed on the outer surface of a precast pile to serve as the anticorrosion layer of the pile foundation, and after a polyurea elastic body is solidified, the polyurea elastic body is coated with polymer mortar to serve as the protection layer of the anticorrosion layer; the anticorrosion coating isolates corrosion to the reinforced concrete pile foundation of corrosive substances contained in silty soil areas, and the durability of the pile foundation is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of building construction. Background technique [0002] With the substantial improvement of people's living environment requirements and the promotion of water conservancy and transportation to industrial development, a large number of buildings have emerged in areas such as coastal areas, rivers and lakes. Due to their special geographical location, a large number of buildings are located in silt or mud Soil area. The water content of silt and muddy soil is close to or exceeds the liquid limit, and the substances contained in it will cause erosion to the pile foundation, affect the durability of the structure, and have a great impact on the service life of the building. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a grouting device capable of ensuring smooth and full grouting of tunnels. [0004] In order to solve the above-mentioned techni...
