Description
Technical field
The utility model relates to and send power transformation technical field, specifically relates to a kind of GIS of Salt Lake Area transformer station equipment Foundations preformed pile that adopts preformed pile to carry out ground processing for the GIS of Salt Lake Area transformer station equipment.
Background technology
Its geological conditions of West of Qinghai Province Salt Lake Area is comparatively special, and foundation soil is salinized soil, has the features such as low bearing capacity, corrosivity be strong; Underground water is higher, and there is severe corrosive, therefore general employing of this area's foundation treatment mode, wrap up in body broken stone pile, cobble and change and the processing mode such as fill out, but body broken stone pile unit price is higher owing to wrapping up in, in transformer station, ground disposal cost is less conventionally, and therefore aspect application in substations, cost performance is lower, cobble changes to be filled out because underground water is higher, Dewatering measure difficulty, is difficult to guarantee cushion construction quality, therefore in this area, is necessary the novel foundation treatment mode of research application.
West of Qinghai Province power grid construction scale continues to increase, Qinghai-Tibet networking, blue or green new networking project complex geologic conditions along the line, and many places are in salinized soil (salt lake, corrosion swampy area).Because construction of structures in transformer station comparatively disperses, ground is processed and is adopted the rear expense of full wafer processing higher, therefore also inapplicable in transformer station, especially in station, some special electric fixturess require high to the bearing capacity of foundation soil and differential settlement, therefore for solving base stabilization and the safety problem of transformer station's construction of structures, in conjunction with existing processing experience and engineering practice, study the application of anticorrosion preformed pile in construction of structures basis, swampy area, salt lake, determine anticorrosion way and construction technology.
Summary of the invention
The technical problems to be solved in the utility model is the deficiency existing for prior art, provides a kind of Salt Lake Area GIS of transformer station equipment Foundations anticorrosion preformed pile.
A kind of Salt Lake Area of the utility model anticorrosion preformed pile of the GIS of transformer station equipment Foundations is achieved by following technical proposals: the anticorrosion preformed pile of a kind of Salt Lake Area GIS of transformer station equipment Foundations comprises precast reinforced concrete piles, Corrosion Protection of Fiber Reinforced Plastics layer, and described Corrosion Protection of Fiber Reinforced Plastics layer is wrapped in precast reinforced concrete piles external surface and is connected with precast reinforced concrete piles is bonding.
A kind of Salt Lake Area of the utility model anticorrosion preformed pile of the GIS of transformer station equipment Foundations has following beneficial effect compared with prior art: a kind of Salt Lake Area of the utility model GIS of transformer station equipment Foundations preformed pile has been coated one deck Corrosion Protection of Fiber Reinforced Plastics layer on former concrete pile foundation, and its advantage is 1. to have solved pile body Anticorrosion; Because Salt Lake Area foundation soil and underground water all have severe corrosive, and groundwater table is higher, common concrete precast pile is also inapplicable in this area, therefore, the utility model has been coated the Corrosion Protection of Fiber Reinforced Plastics layer that one deck has stronger corrosion resistance and water proofing property characteristic on former concrete pile foundation, has solved well pile body corrosion-resistant problem.
By the experience at Salt Lake Area similar engineering, this material of glass fiber reinforced plastic has stronger corrosion resistance and water proofing property, and this material and preformed pile body bonding firmly, should not come off, therefore as preformed pile outer anticorrosion be material preferably; By improving the concrete intensity of pile body body, also can increase substantially the resistance to corrosion of pile body simultaneously.
2. the anticorrosion construction of prefabricated piles technique of the GIS of the utility model Salt Lake Area transformer station equipment Foundations; Because Salt Lake Area groundwater table is higher, surface soil layer bearing capacity is lower, large-scale sinking apparatus is easily absorbed in, thereby cause comparatively difficulty of pile sinking work, the feature that is therefore composite foundation in conjunction with this processing mode, the construction technology that preformed pile is processed is adjusted, first in former foundation ditch bottom, hardcore bed is set, and then carry out pile sinking work, because cone-shaped is made in the anticorrosion preformed pile of the utility model bottom, pile sinking is easy to.After pile sinking work completes, again top bed course is processed and is encased inside bituminous concrete, the solution that the utility model form of construction work is good underground water to the difficulty that causes of construction.
3. the anticorrosion preformed pile processing mode of the utility model cost performance is higher; Because Salt Lake Area ground prior art processing mode is general, adopts and wrap up in body broken stone pile, through measuring and calculating, the anticorrosion preformed pile engineering of the GIS of Salt Lake Area transformer station equipment Foundations is wrapped up in approximately 1,300 ten thousand yuan of body broken stone pile construction costs as what adopt original technology, and the GIS of transformer station equipment Foundations anticorrosion construction of prefabricated piles journey in the utility model Salt Lake Area adopts and wraps up in after body preformed pile approximately 3,500,000 yuan of construction costs, therefore this processing mode has larger investment advantage, and cost performance is higher.
4. because Salt Lake Area lacks conventional building material, solved the problem that lacks conventional building material after therefore adopting the anticorrosion preformed pile of the utility model, and the transportation of anticorrosion preformed pile more for convenience.
Adopt after the anticorrosion precast concrete pile of the utility model, improved the bearing capacity of foundation soil; Adopt after glass fiber reinforced plastic parcel, solved pile body corrosion-resistant problem.Relatively comprehensive, the anticorrosion preformed pile pile body of a kind of Salt Lake Area of the utility model GIS of transformer station equipment Foundations and construction technology processing mode unit price are low, can be widely used in the based process of Salt Lake Area transformer station main equipment.
