Description
Technical field
The invention belongs to field of bridge construction, and in particular to a kind of viaduct curve anti-collision wall is logical across precast construction method.
Background technique
With the fast development of overhead road of city highway, the landscape of modern city is higher to the appearance requirement of bridge, anti-collision wall
As the safety prevention measure of sky way bridge, peculiar direction of traffic structure curve, the quality buffer vehicle of armored concrete
Impact force improves safety coefficient, protects people's lives and properties.Currently, anti-collision wall main construction techniques are still traditional entirety
Cast-in-place, site operation, which is poured, causes many influences to ambient enviroment and road traffic, and construction efficiency is low, and loss is high, and
It is traditional pour mode often and will cause the color of whole anti-collision wall, the problems such as quality is uneven.
Summary of the invention
Aiming at the problems existing in the prior art, the present invention provides a kind of logical across prefabricated construction side of viaduct curve anti-collision wall
Method can preferably guarantee the globality of anti-collision wall Yu main body box-beam structure, while also ensure that anti-collision wall streamline is smooth and beautiful.
To achieve the above object, the invention adopts the following technical scheme:
A kind of viaduct curve anti-collision wall is logical across precast construction method, and this method includes following construction process: box girder tensioning
Mud jacking completes → box beam is moved into spring quantum under the prefabricated place of anti-collision wall → measurement box girder tensioning and overall dimensions → according to case
Actual condition setting control line after erection → in box beam upper bracket construction → reinforcing bar binding → pipeline installs correction → inside
Mould installs correction → outer side mold and installs correction → casting concrete.
The setting control line includes surveying setting-out and vertical control survey,
Surveying setting-out is the control line by drawing measuring anti-collision wall, and absolute altitude control line is arranged on anti-collision wall reserved steel bar,
The linear and absolute altitude of strict control anti-collision wall, use the structure centre line of total station measuring box beam as control internal model reference line,
Actual measurement actual quantities is carried out to the spring quantum of box beam simultaneously, convenient for being adjusted in installation template, specifically includes the following steps:
Step 1, cloth observing and controlling net selects spacious place placement control point, observes horizontal angle using survey time method, use whole station
The three-dimensional coordinate of the horizontal distance and two control point A, B between adjacent two control points A, B is observed and recorded to instrument,
Step 2, the inside and outside boundary line of anti-collision wall is scheduled case by the design position of anti-collision wall by the control of box beam levelness
On the top surface of beam, and marking, every side anti-collision wall releases inside and outside two boundary lines,
According to design requirement, the live anti-collision wall gradient is simulated, according to the working principle of horizontal line of sight in level, according to
The measured value of levelling rod reads height value a, b of control point A, B point-to-point transmission, calculates the difference in height h between control point A, BAB,
It determines the need for measuring and goes out the corresponding gradient, according to the height difference h measuredABThe height of regulating box beam bottom portion adjustable backing plate until
Control point levels box beam bottom on the same water surface, if necessary to the side gradient, according to design requirement, using can
The steel plate of adjusting is corrected the gradient in measurement, until there is the correspondence gradient of corresponding box beam,
Step 3, total station is placed on survey station control point by the control of box beam absolute altitude, is had after centering, leveling to every Pin
The box beam of anti-collision wall carries out the level measurement of beam face, measures the height of A, B two o'clock respectively, and the height for measuring prism is h0, obtains every
The actual height of every Pin box beam is obtained difference by the actual height h1 of Pin box beam compared with design height, which is then adjustable
The height that section backing plate needs to adjust, the box beam to every Pin with anti-collision wall carry out the level measurement of beam face, facilitate anticollision wall form tune
Section meets design specification to corresponding height with the whole height for ensuring box beam and anti-collision wall,
It surveys site information setting: entering survey station point information input screen, input the details of the survey station point: point number, instrument
Device is high, point number encodes and confirms,
The setting of backsight point information: entering backsight point information input screen, inputs backsight point number, calibrates when completing backsight point
Afterwards, start detail point measurement.In order to guarantee to pour the presentation quality of rear anti-crash wall, when measurement, encrypts detail point, every Pin box beam
It is measured by mono- point of 2m,
Step 4, anti-collision wall level measurement carries out level measurement to every Pin anti-collision wall using total station 10 according to step 3, point
The height for not measuring A, B two o'clock, the height for measuring prism is h0, the actual height h2 of every Pin anti-collision wall is obtained, by every Pin anticollision
The actual height of wall obtains difference compared with design height, which is then the height that adjustable backing plate needs to adjust, in anticollision
After the completion of the equal formwork of internal model and external mold of wall, anti-collision wall absolute altitude repetition measurement is carried out, if after repetition measurement, the actual height and design of anti-collision wall
The error of height is more than 2mm, then needs to readjust adjustable backing plate height, until error is within the scope of 2mm.
