Description
Technical field
The present invention relates to a kind of building high pier construction method, being specifically related to the high pier of a kind of building from promoting walking template construction method.
Background technology
At present, the whole nation every year nearly 2.3 ten thousand kilometers of speedways goes into operation or is building, and wherein, having an appointment 1.1 ten thousand kilometers is in west area construction.And west area mostly is remote mountains area or Freeway of Mountain Range, surface relief is large, and massif is precipitous, gully jet-bedding is widely distributed, and this brings many difficulties to the construction of speedway.Particularly in order to cross over deep mountain valleys, bridge pier need be built and carry out supporting bridge panel.Traditional high pier construction, main employing turns over the construction methods such as mould, creeping formwork, sliding formwork, and uses these methods construct, or because of construction speed slow, or because of presentation quality poor, or because of reasons such as construction safety degree are low, gradually can not adapt to the construction requirement in modern times.
The Chinese invention patent being CN103147403A as publication number discloses a kind of roller die construction method for bridge high pier, use roller mould device, save after concreting completes at pier shaft one, utilize roller die conputer controlled Hoisting System, precise elevation template, in lifting process, outside framework scrolls up at liner mould external surface, guarantee that liner mould and concrete face keep static, after rising to assigned address, liner mould, brushing release agent, assembling reinforcement, concreting is reinstalled inside outside framework, then climbing shuttering, and so forth operation again, until this pier stud has been constructed.
According to prior art, liner template is promoted by roll mode, but liner template easily produces distortion under concrete lateral pressure effect; Main mould bases had both needed at liner mould rolls on surfaces, need again to utilize main mould bases to apply certain clamping force to offset concrete lateral pressure to liner mould, the fit dimension of winner's mould bases and liner mould is required very high, once dimensional errors, easily cause liner template movement, Surface Quality of Concrete declines serious; Main mould bases and liner mould are tight fit, cause the high pier center line difficulty of adjustment, once occur that deviation needs adjustment, easily cause support bar flexural deformation even to fracture; And main mould bases had both needed at liner mould rolls on surfaces, need again to utilize main mould bases to apply certain clamping force to offset concrete lateral pressure to liner mould, the fit dimension of winner's mould bases and liner mould is required very high, once dimensional errors, easily cause liner template movement, Surface Quality of Concrete is declined serious.
On construction period, of the prior artly turn over mould, creeping formwork about 3 to 4 days workflows, average every day, concreting height was 1-1.2 rice, roller die construction every day about 4 meters, and Modern Construction often requires the construction speed of about 5 meters every day.
