Description

A kind of Temporary Piers construction method adopting assembling heavy steel tube bracing or strutting arrangement
Technical field
The present invention relates to bridge building operations technical field, be specifically related to a kind of Temporary Piers construction method adopting assembling heavy steel tube bracing or strutting arrangement.
Background technology
In bridge construction technical field, push construction method is applied to the construction of continuous girder bridge and cable-stayed bridge more, be specially, beam body is paragraph by paragraph pouring or assembled on platform for lining, then with the longitudinal pushing tow of jack, make beam body by the interim sliding support face of each Dun Ding, construction method in place after adjustment.Incremental launching construction arranges construction plant on the ground at the rear of abutment, segmented builds or spelling beam body, before beam body, installation length is the steel nose girder of pushing tow across footpath designated ratio, then exerted a force by level jack, by beam body forwards pushing tow go out construction plant, repeat these operations and can complete whole beam body construction.
In the incremental launching construction of bridge, spacing for bridge pier is wider, the bridge that span is larger, because beam body span ability is limited, therefore need also need to arrange Temporary Piers between permanent pier, in incremental launching construction process, interim supporting role is played to beam body, make beam body smoothly by bridge pier next on pushing tow.
In pushing tow operation process, namely Temporary Piers will bear the vertical pressure that the transmission of beam body is got off, and also will bear in pushing tow process, certain horizontal force that beam body is bestowed, this just requires that Temporary Piers must have enough intensity, rigidity and stability simultaneously.
Current Temporary Piers, normally has two kinds of structures, and a kind of is the Temporary Piers adopting the mode of building to obtain concrete structure, and a kind of is adopt the assembled truss-like Temporary Piers obtained of rod member.For the Temporary Piers of concrete structure, it has good structural strength, but its work progress and permanent pier similar, whole work progress operation is numerous, not only needs the man-hour of at substantial, but also significantly increases construction cost, after bridge construction, remove in Temporary Piers process, also need the input of a large amount of man power and material, significantly increase construction cost; For truss-like Temporary Piers, its simple structure, convenient installation, also convenient dismounting, has not only saved cost, has yet shortened the duration, reduce human cost, but the Temporary Piers of this truss-like, its vertical enabling capabilities of its structural strength or the enabling capabilities of horizontal direction all more weak, so the present use of this truss-like Temporary Piers; And, the Temporary Piers of this truss-like, owing to being adopt welding or to be other forms ofly fixedly connected with between some component, so, when splitting out, need to adopt the destructive mode that splits out to split out, after splitting out, these components can not be reused again, so, also there is certain waste, cause the increase of construction cost.
So, need badly at present and a kind of both there is enough intensity, rigidity and stability, guarantee to carry out secure support to beam body, can conveniently install and split out again, reuse, reduce the construction method of construction cost.
Summary of the invention
The object of the invention is to: in current bridge building operations, the problems referred to above that Temporary Piers construction exists, there is provided a kind of and both there is enough intensity, rigidity and stability, guarantee to carry out secure support to beam body, can conveniently install and split out again, reuse, reduce the construction method of construction cost.
