The problem such as inaccurate, has had a strong impact on the service life of bridge.
Summary of the invention
It is desirable to provide the installation method of a kind of bridge pad, well solve the problems referred to above, its operation
Simply, by laser orientation instru-ment, bridge pad is carried out unwrapping wire location, it is ensured that the installation accuracy of bridge pad,
Installation process normative and reasonable simultaneously, bearing firmly installs, it is ensured that the serviceability of bridge pad and use longevity
Life.
The technical scheme is that the installation method of a kind of bridge pad, including step:
A. mortar is prepared；
B. use laser orientation instru-ment that bearing is carried out unwrapping wire location；
C., anchor bolt and bearing are installed；
D. installation form；
E. perfusion mortar；
F. erection support and the anchor bolt of superstructure.
Further, before carrying out described step a, pier top dabbing need to be cleared up, carve bearing support with ferrum
Face carries out dabbing, and dabbing degree meets the bridge concrete construction regulation about treatment of construction joints, and by end face
Clean out.
Further, also need to clear up preformed hole before carrying out described step a, check before cleaning and check pier top anchor
The position in fixing bolt hole, size and the degree of depth, qualified rear thoroughly cleaning.
Further, in described step a, mortar is condensation compensation mortar, the water of described condensation compensation mortar
Glue ratio is 0.465, and its intensity is not less than 35MPa.
Further, in described step c, in bearing corner, base-plate is looked for by gad with pier face pad
Flat, base-plate bottom surface preferably exceeds pier top 20mm～50mm, then checks and installs centrage and elevation.
Further, propping up side form along bearing surrounding in described step d, template is along bridge pier axis of pitch direction two
Side size should be greater than each 100mm of bearing width.
Further, described step e is used condensation compensation mortar between bolt hole and base-plate and pier face
Gap is filled, and pours into from one end and flows out and aerofluxus from the other end, it is ensured that without hollowing during perfusion.
Further, before carrying out described step f, the mortar such as need reaches design strength recession except corner gad,
And use epoxy resin mortar joint filling.
The invention has the beneficial effects as follows:
1, by laser orientation instru-ment, bridge pad is carried out unwrapping wire location, it is ensured that the installation essence of bridge pad
Degree, further ensures the installation accuracy of bridge, makes bridge pad uniform force, it is ensured that bridge pad
Serviceability；
2, mortar is condensation compensation mortar, and the water-cement ratio of condensation compensation mortar is 0.465, and its intensity is not less than
35MPa, the mortar strength that the present invention uses is high, and in energy rapid draing, and work progress, stress is gentle, no
Deformation and the displacement of bridge pad can be caused, thus ensure that the installation accuracy of bridge pad；
3, installation process normative and reasonable, bearing firmly installs, it is ensured that the serviceability of bridge pad and making
Use the life-span.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, so that the present invention is entered
One step describes in detail.
The invention provides the installation method of a kind of bridge pad, including step:
A. preparing mortar, mortar is condensation compensation mortar, and the water-cement ratio of described condensation compensation mortar is 0.465,
Its intensity is not less than 35MPa, before carrying out described step a, need to clear up pier top dabbing, carves propping up with ferrum
Seat bearing-surface carries out dabbing, and dabbing degree meets the bridge concrete construction regulation about treatment of construction joints, and
End face is cleaned out, also needs to clear up preformed hole before carrying out described step a, check before cleaning and check pier top
The position in anchor bolt hole, size and the degree of depth, qualified rear thoroughly cleaning；
B. use laser orientation instru-ment that bearing is carried out unwrapping wire location；
C., anchor bolt and bearing are installed, at bearing corner gad, base-plate are looked for pier face pad
Flat, base-plate bottom surface preferably exceeds pier top 20mm～50mm, then checks and installs centrage and elevation；
D. installation form, props up side form along bearing surrounding, and template should along both sides, bridge pier axis of pitch direction size
More than each 100mm of bearing width；
E. perfusion mortar, fills bolt hole and base-plate with condensation compensation mortar with gap, pier face,
Pour into from one end during perfusion and flow out and aerofluxus from the other end, it is ensured that without hollowing；
F. the anchor bolt of erection support and superstructure, before carrying out described step f, the mortar such as need reaches to set
Meter intensity recession is except corner gad, and uses epoxy resin mortar joint filling.
The present invention carries out unwrapping wire location by laser orientation instru-ment to bridge pad, it is ensured that the installation of bridge pad
