Abstract

The invention relates to a capsule type anti-corrosion device with a pile shoe and an anti-corrosion and construction method using the device, the capsule type anti-corrosion device comprises a cylindrical coating capsule body made of anti-corrosion material, the inner surface and the outer surface of the coating capsule body are uneven surfaces, a supporting bottom is arranged at the lower part in the coating capsule body, the periphery of the supporting bottom is connected with the side wall of the coating capsule body, the hard anti-corrosion pile shoe is arranged in the coating capsule body, which is positioned at the lower end of the supporting bottom, at least one grouting pipe is arranged near to the outer side of the coating capsule body along the axial line direction the coating capsule body, the bottom end of each grouting pipe extends to the place which is near to the bottom end of the coating capsule body, and a low-pressure grouting hole and a plurality of high-pressure grouting holes are respectively arranged at the lower part of each grouting pipe, which is near to the supporting bottom. The invention aims at providing the capsule type anti-corrosion device with the pile shoe, which has reliable long-term anti-corrosion performance in a pile foundation and a composite foundation in a highly corrosive brine formation, and can reduce the expensive maintenance cost of the foundations of buildings and structures in the corrosive formation, and the anti-corrosion and construction method using the device.

Description

technical field

[0001] The invention relates to an anticorrosion and erosion-resistant anticorrosion device with spud cans for the pile foundation and composite foundation of various traffic engineering, industrial and civil construction projects, and anticorrosion piles made by the device and corresponding construction methods. Background technique

[0002] At present, whether it is the offshore engineering construction carried out in the site with water conservancy connection with seawater, or the large-scale infrastructure project carried out in the inland salt lake area, they all face the problem of corrosion, erosion and denudation of general building materials by the brine formation, so that they are forced to Reduce the design life of the building and cause high post-project maintenance costs. Some surveys and related tests on buildings and structures in corrosive sites have shown that the brine or salt lake environment, and the saline soil layer around the salt lake...
