Abstract
The invention relates to the field of electric power system construction, in particular to a foundation construction method of a water-glass anti-corrosion pile in saline soil areas. The foundation construction method of the water-glass anti-corrosion pile in saline soil areas provided by the invention comprises the following steps: manufacturing a filling pile drill hole and a concrete injection hole, putting a steel jacket in the filling pile drill hole, filling water-glass in the steel jacket, then filling concrete in the concrete injection hole, slowly elevating the steel jacket by utilizing an elevator along with the filling of concrete, continuously filling water-glass in the steel jacket, and pulling out the steel jacket after the construction is finished, wherein the exterior of the concrete is completely wrapped by the water-glass. The foundation construction method of the water-glass anti-corrosion pile in saline soil areas provided by the invention solves the problem that the corrosion resistance is poor by using a traditional pile foundation construction method in saline soil areas, and realizes integration of corrosion resistance and construction; the foundation construction method has the characteristics of high efficiency, high construction speed and the like, and is wide in application prospect.
Description
Technical field
The present invention relates to a kind of power system construction field, particularly the anticorrosion pile foundation construction method of a kind of saline soil area water glass.
Background technology
Power system mainly comprises the generator of power plant, step-up substation, transmission line of electricity, stepdown substation, electrical distribution system and user's composition, and wherein transmission line of electricity is the important component part of whole system.
Along with the fast development of electric utility, transmission line construction has extended to salt marsh soil, but the salinized soil in these areas is to the corrosion on tower bar basis, is an insoluble large problem for a long time.Traditional method of executing is excavation pit, and then formwork in foundation ditch carries out reinforcing bar configuration, concreting, removes mould after concrete setting, finally also will carry out maintenance to concrete foundation, construction period is longer, and the maximum problem in this basis is cannot be anticorrosive.In saline soil area, the compound of the salt in soil particularly sulfate, villaumite and magnesium salts corrodes the most serious, makes the life-span on basis less than 10 years, and what have is less than 1 year and just produces crack.
For addressing these problems, one need be invented and be applicable to the anticorrosion pile foundation construction method of saline soil area water glass.
Summary of the invention
The object of the invention is the problem using the anticorrosive difference of traditional pile foundation construction method in saline soil area, provide the anticorrosion pile foundation construction method of a kind of saline soil area water glass.
