Description
Technical field
The invention belongs to segment bridge prefabrication technical field of construction, it is related to that a kind of segment bridge prefabrication is linear to be automatically controlled
System.
Background technology
The prefabricated place of segmental construction bridges is often positioned in bridge site neighbouring position, and geological conditions is poor, is susceptible to measurement
The displacement of benchmark tower, to influence the matched precision of short line casting segmental construction.Therefore, it is proposed to which a kind of tower that will measure is consolidated with end mould
The measurement method of knot, this method be the setting-out stage lay six measuring point components, by measure measuring point component between distance and
Angle determines the relative position when Anterior Segment and matching segment.Since prefabricated Geological condition is generally poor, benchmark tower with
Certain displacement often occurs within the construction period for target tower.Simultaneously as the deviation of benchmark tower and target tower is checked when expending
Between it is longer, when practical engineering application, the check of benchmark tower and target tower, ordinary circumstance will not be carried out before each segmental construction
Next month, is once checked.And within the construction period of this month, the deviation construction party of benchmark tower and the generation of target tower
It is unknown.When determining horizontal position using conventional construction method as a result, since theoretical centerline is changed, it will make
Each segment horizontal relative position measurement error, and this error becomes larger rapidly with the increase for pouring cycle, finally makes
The central axis deviation for obtaining bridge exceeds License Value range.In addition, outside reference tower by external environment for example weather, temperature, wind-force,
Ambient vibration etc. is affected, and is adversely affected to the precision of segment bridge prefabrication construction.
And traditional segment bridge setting-out is all made of artificial setting-out, need to check adjustment repeatedly according to total station survey data
With fragment position, until meeting setting-out error requirements.This process automation degree is low, setting out survey program, matching fragment position tune
It is long that whole program and oxygen evolution rate check not only consumption time, but also is easy to be influenced by survey crew's operation, production efficiency need into
One step improves.Furthermore the LFM signal method of segment bridge mostly uses external development and completes, and needs putting each segment
Sample data, time measured data are input manually into software, the setting out data of next segment are calculated via software, process complexity is cumbersome.
