Abstract
The invention relates to the field of bridges, in particular to a steel bright pier installation technology. Firstly, after a pier frame and pier studs are prefabricated on a plant production line according to the actual bridge building drawing requirements and are transported to a bridge building site; as the road surface is unsmooth, the pier studs need to be embedded in the ground firstly, it is guaranteed that the upper surfaces of the installed pier studs are located on the same horizontal face, and then the overall pier frame is stably placed on the pier studs and fixed through bolts; and it is guaranteed that C30 concrete casting in place is carried out after the pier frame is firmly and stably placed on the pier studs, the pier studs, the ground and the pier are tightly and firmly connected together, and therefore the load of the overall bridge is conveniently supported. The steel bright pier installation technology is simple in design, convenient to construct and short in construction period; and the problems that the overall bridge structure is unstable due to insufficient contact between the pier and the ground in a common pier stud installation process, and casting of concrete is uneven are solved, pier installation is more firm, and the load of the overall bridge can be supported.
Description
Technical field
The present invention relates to bridge field, particularly relate to steel bridge bridge pier mounting technique.
Background technology
At present, bridge construction has abandoned traditional form of construction work gradually, is more and more tending towards adopting steel plate to build skeleton, then uses the mode of concreting.In the building course of bridge, it is particularly important that the construction of bridge pier is installed, only have bridge pier install steadily firmly after, the weight of bed rearrangement bridge can be supported.General bridge pier is all the structure adopting bridge pier and pier stud to be integrated in installation process, so just the contact area of bridge pier and ground is diminished, the load of bearing just corresponding reduction, often occur that concreting uneven when bridge pier is built simultaneously, between bridge pier and ground contact surface, have gap to cause bridge pier that the problems such as not steady are installed.
Summary of the invention
The present invention is just in order to solve the deficiency in above-mentioned bridge pier installation process, provide a kind of steel bridge bridge pier mounting technique, the method makes the contact area on bridge pier and ground in bridge pier installation process larger, the load that can bear is larger, ensure that the stationarity of bed rearrangement steel bridge, and better achieve fully contacting of bridge pier and ground, effectively can support the load of bed rearrangement bridge, and shorten the construction period of bridge.
To achieve these goals, the present invention adopts following technical method to realize: steel bridge bridge pier mounting technique, be first according to actual bridge construction drawing requirement by bridge pier framework and pier stud shop production line is prefabricated complete after, be transported to bridge construction ground,
First by pre-buried for prefabricated pier stud in ground, and guarantee that the upper surface of mounted pier stud is in same level, again bridge pier framework bolt is fixed on pier stud stably, then carries out cast in situs with C30 concrete, built and regularly carried out concrete maintenance work afterwards.
Described steel bridge bridge pier framework, good at workshop Plate Welding according to actual bridge construction drawing requirement, its stationarity must be ensured when mounted.
Described pier stud, good in shop-fabricated according to unified specification according to actual bridge construction drawing requirement, when installing with building, its upper surface must ensure in same level.
Described bridge pier framework was realized by Bolt Connection with connecting of pier stud, was first by after pre-buried for pier stud getting well, was placed on stably on pier stud by bridge pier framework, fixes with bolt.
The invention has the beneficial effects as follows: by steel bridge bridge pier mounting technique in the present invention, bridge pier framework can be made more steady, and bridge pier and contact area of ground are larger, and bearing load ability is stronger, the load of support bed rearrangement bridge that can be strong, shortens the construction period of bridge.
Accompanying drawing explanation
Fig. 1 is bridge pier scheme of installation on the right side of steel bridge; Fig. 2 is that on the right side of steel bridge, left view installed by bridge pier; Fig. 3 is whole steel bridge bridge pier scheme of installation.Wherein 1 is steel bridge bridge pier framework, and 2 is pier studs, and 3 is ground, and 4 is bolts.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described: as depicted in figs. 1 and 2, steel bridge bridge pier mounting technique, by the size first according to bridge pier and pier stud drawing requirement in actual bridge construction, at shop production line by steel bridge bridge pier framework 1, pier stud 2 is prefabricated to be completed, then bridge construction ground is transported to, consider that ground 3 is rough, need first to arrive 3 li, ground by pre-buried for pier stud 2, and the upper surface guaranteeing pre-buried good pier stud 2 in the same horizontal line, afterwards bridge pier framework 1 is placed on pier stud 2 stably, and with bolt 4, bridge pier framework 1 is fixed on pier stud 2, as shown in Figure 3, by pre-buried for bed rearrangement bridge pier column 2 good after, be fixed on pier stud 2 by bridge pier framework 1 with bolt 4, fixation is built with C30 concrete later, has built regularly to carry out concrete maintenance work afterwards.
By steel bridge bridge pier mounting technique in the present invention, bridge pier can be made to install steadily, larger with the contact area on ground, the ability of bearing load is stronger, the weight supporting bed rearrangement steel bridge that can be strong.
