Description
Technical field
The present invention relates to a kind of power system construction field, particularly a kind of saline soil area waterglass anticorrosion pile foundation construction method.
Background technology
Power system mainly includes the electromotor in power plant, step-up substation, transmission line of electricity, stepdown substation, 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 been extended to salting soil, but the corrosion that the salinized soil in these areas is to tower bar basis, it is an insoluble big problem for a long time. Traditional method of executing is excavation pit, formwork in foundation ditch, then carries out reinforcing bar configuration, casting concrete, removes mould after concrete setting, finally also concrete foundation is carried out maintenance, construction period is longer, and the maximum problem in this basis is cannot be anticorrosive. The compound of the particularly sulfate of the salt in saline soil area, soil, villaumite and magnesium salt corrodes the most serious so that the life-span on basis, being less than a year of having just produced crack less than 10 years.
For solving these problems, need to invent a kind of suitable in saline soil area waterglass anticorrosion pile foundation construction method.
Summary of the invention
The problem that it is an object of the invention to use traditional anticorrosive difference of pile foundation construction method in saline soil area, it is provided that a kind of saline soil area waterglass anticorrosion pile foundation construction method.
A kind of saline soil area provided by the invention waterglass anticorrosion pile foundation construction method includes making bored concrete pile boring and concrete hand-hole, steel bushing is placed in described bored concrete pile is holed, waterglass is poured into described steel bushing, then penetration concrete in described concrete hand-hole, concrete pour into along with described, utilize and described in elevator, described steel bushing is slowly lifted up, described waterglass continues to pour into described steel bushing, after having constructed, described steel bushing is extracted, is all wrapped up by described waterglass outside described concrete.
Further, described steel bushing is double-deck.
Further, described steel bushing surrounds described concrete hand-hole.
Further, before pouring into described concrete in described concrete hand-hole, described waterglass should fill the bottom of described concrete hand-hole by described steel bushing.
Further, when utilizing described elevator slowly to be lifted up by steel bushing, it is ensured that lower than the described TOC poured into bottom described steel bushing.
A kind of saline soil area provided by the invention waterglass anticorrosion pile foundation construction method, solve the problem using traditional anticorrosive difference of pile foundation construction method in saline soil area, achieve anticorrosive construction integration, especially when work transmission line king-pile length is shorter, having the features such as efficiency height, speed of application be fast, application prospect is extensive.
Other features and advantages of the present invention will be set forth in the following description, and, partly become apparent from description, or understand by implementing the present invention. The purpose of the present invention and other advantages can be realized by structure specifically noted in the description write, claims and accompanying drawing and be obtained.
