Abstract
The invention discloses an everfrost and saline soil region transmission line pole glass fiber reinforced plastic foundation construction method and relates to a construction method of a transmission line pole foundation in an everfrost and saline soil region, in particular to a mold construction method taking the glass fiber reinforced plastic as the transmission line pole foundation. The method is characterized in that first making the glass fiber reinforced plastic material into molding foundation form according to the shape of the foundation; then excavating a pit; subsequently, putting the molding foundation form in the pit, arranging reinforcing steel bar in the molding foundation form and casting concrete; and finally, backfilling soil in the pit immediately.
Description
Technical field
The present invention relates to a kind of at ever-frozen ground and saline soil area, the job practices on power transmission line column bar basis, particularly a kind of with the job practices of glass fiber reinforced plastic as the mould on power transmission line column bar basis.
Background technology
Along with the fast development of electric utility, power grid construction has progressively extended to the ever-frozen ground and the saline soil area of Qinghai-Tibet Platean.Yet,, be an insoluble for a long time hard nut to crack in frost heave and the corrosion of these regional ever-frozen ground and salinized soil to tower bar basis.Traditional job practices is an excavation pit, and formwork in foundation ditch carries out the reinforcing bar configuration then, and concreting is treated to remove mould after the concrete setting, also will carry out maintenance to concrete foundation at last.Construction period is longer.The maximum problem in this basis is can't frost heaving resistant and anticorrosive.In the frozen soil area,, cause blackout because bar and the accident of falling the tower often take place basic unstability.At saline soil area, the salt in the soil particularly compound erosion of sulfate, villaumite and magnesium salts is the most serious, makes life-span on basis less than 10 years, and what have is less than 1 year and just produces the crack.Be ever-frozen ground be again the area of salinized soil, above-mentioned two kinds of problems exist simultaneously.
The content of invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of and mix regional frost heaving resistant and anticorrosive at ever-frozen ground, saline soil area and ever-frozen ground, salinized soil, and short power transmission line column bar foundation construction method of construction period.
Technical scheme of the present invention is: be characterized in, at first, according to the shape on basis, make the moulding foundation forms with glass-reinforced plastic material; Then, excavation pit; Secondly, glass fiber reinforced plastic moulding foundation forms is put into foundation ditch, configuration reinforcement and concreting in the moulding foundation forms; At last, the hole of backfill immediately soil.
Another characteristics of the present invention are that described glass fiber reinforced plastic moulding foundation forms can be a template assembly, assemble during construction again.
The present invention has following advantage and effect: 1, because ever-frozen ground mainly is the effect of tangential frost-heave force to the harm of pole and tower foundation, and the stability on the uplift force influence basis that acts on surface of base that forms when the soil body moves upward; Tangential frost-heave force is relevant with the roughness of surface of base to the size of basis influence.Because the glass fiber reinforced plastic smooth outer surface so greatly reduce the influence of uplift force to the basis, makes power transmission line column bar basis safety and stability.2, the greatest problem of saline soil area pole and tower foundation is the corrosion failure of salt to concrete products, salt is generally sulfate attack and the compound erosion of sulfate, villaumite and magnesium salts to the corrosion of concrete products, especially attaches most importance to the compound erosion of sulfate, villaumite and magnesium salts.Glass steel formwork is a kind of material simple, that thermal insulation is good, antiseptic property is strong of processing.So adopt the glass steel formwork of not dismantling to stop the concrete heat of hydration to pass to ever-frozen ground on every side, can stop of the erosion of extraneous corrosive medium again to concrete foundation.3, because glass steel formwork need not be dismantled, cheat soil backfill immediately after the concrete pouring, so the construction period shortens dramatically.

The specific embodiment
Embodiment 1, as Fig. 1, according to the shape (as the awl cylindricality among Fig. 1) on basis, make moulding foundation forms 1 with glass-reinforced plastic material; Excavation pit 2 then; Glass fiber reinforced plastic moulding foundation forms 1 is put into foundation ditch 2, configuration reinforcement and concreting in moulding foundation forms 1; The hole of backfill immediately at last soil.
Embodiment 3, as Fig. 3, according to the shape (as the step cylindricality among Fig. 3) on basis, make moulding foundation forms 1 with glass-reinforced plastic material; Excavation pit 2 then; Glass fiber reinforced plastic moulding foundation forms 1 is put into foundation ditch 2, configuration reinforcement and concreting in moulding foundation forms 1; The hole of backfill immediately at last soil.
Embodiment 4, according to the shape on basis, make template assembly with glass-reinforced plastic material; Excavation pit then; In foundation ditch, carry out the assembling of template assembly, configuration reinforcement and concreting in the template that assembles; The hole of backfill immediately at last soil.
Embodiment 5, according to the shape on basis, make template assembly with glass-reinforced plastic material; Excavation pit then; Configuration reinforcement in foundation ditch carries out the assembling of template assembly, again concreting on the reinforcing bar that has configured; The hole of backfill immediately at last soil.
Claims (2)
1, ever-frozen ground and saline soil area power transmission line column pole glass fiber reinforced plastic foundation construction method is characterized in that at first, according to the shape on basis, make the moulding foundation forms with glass-reinforced plastic material; Then, excavation pit; Secondly, glass fiber reinforced plastic moulding foundation forms is put into foundation ditch, configuration reinforcement and concreting in the moulding foundation forms; At last, the hole of backfill immediately soil.
