Embodiment Construction

[0053] Examples see figure 1 As shown, an implanted anti-corrosion prefabricated pile applied in a saline soil foundation includes a prefabricated concrete pile body 1, the periphery of the pile body 1 is tightly wrapped with anti-corrosion cloth 3, and a steel pile is installed at the implanted end of the pile body Point 2, the steel pile point 2 is a conical welded on the lower surface of the base plate 2.2 formed by a group of rib plates 2.1, and a snap ring 2.3 is welded on the upper surface of the base plate, the inner diameter of the snap ring 2.3 is in line with the outer diameter of the pile body 1 The diameters are equal, and the bottom of the pile body is snapped into the snap ring 2.3, and the anti-corrosion cloth 3 is a geotextile made of anti-corrosion materials.

[0054] The outer surfaces of the pile body 1 and the anti-corrosion cloth 3 are all coated with anti-corrosion materials.

[0055] The cross section of the pile body 1 and the snap ring 2.3 is circula...

Abstract

The invention relates to an implantable corrosion-proof preformed pile for use in a salt oil foundation and a construction method thereof. A corrosion-proof effect is achieved by prefabricating a pile body and a pile tip and tightly wrapping the pile body with a soil synthesized material and a corrosion-proof material. In a construction process, the pile tip is pre-delivered to a designed level first, then the pile body is protected and implanted into a pile hole to be jointed with the pile tip, and a gap between the hole and the pile is compacted later. The method has the following advantages that: 1, the integrity of a corrosion-proof layer outside the pile body is guaranteed; and 2, the engineering properties of the pile are guaranteed to be identical with those of static compression and driving pile sinking, the construction speed of the method is higher than that of a pouring pile or other pile construction, operation is easy, the corrosion-proof layer of the pile body is protected from damage, the corrosion-proof effect is good, engineering cost is reduced, a great amount of materials are saved, and the engineering quality of the foundation in salt soil areas is guaranteed. The implantable corrosion-proof preformed pile and the construction method thereof are suitable for pile foundation engineering of the salt soil foundation.

Description

technical field [0001] The invention relates to an implanted anti-corrosion prefabricated pile and a construction method thereof, in particular to an implanted anti-corrosion prefabricated pile suitable for use in saline soil foundations and a construction method thereof. Background technique [0002] In saline soil areas rich in brine, the foundation soil has low mechanical strength and high compressibility. General buildings must use artificial foundations and pile foundations; important buildings and railway road bridges must use reinforced concrete pile foundations. Because the foundation soil of saline soil contains brine of sulfate and chloride ions that are highly corrosive to steel, concrete and other building materials. Steel and concrete are the main building materials of various important buildings at present, so the anticorrosion of steel structures and concrete in saline soil areas has always been the research and development goal of construction industry perso...
