Referring to figs. 1 through Fig. 5, a kind of precast segment bridge erection on-site measurement method provided by the invention, comprises the following steps:
(1), auxiliary base point 4 is selected: select a correct position as the auxiliary base point 4 measured at bridge construction place periphery, the elevation at auxiliary base point 4 place meets measures requirement, not easily be blocked, and remain in bridge construction process and immobilize; Auxiliary survey selected by requirement on schedule 4 positions is obvious, highly suitable, is not easily blocked, afterwards total powerstation is positioned over this position, prepare to measure the position of beam section; By designing requirement location first joint beam section 2 after bridge pier 1 is constructed, first joint beam section 2 is as the datum line beam section of follow-up all beam sections, and the accurate location of himself is very important.The reference mark theoretical coordinate buried underground after factory for prefabrication completes due to beam section and actual coordinate have certain deviation, adjust the position, reference mark that head saves beam section by dividing middle arrow method equally, determine the position of first joint beam section 2 on this basis;
(2), measuring point 5 is arranged: construct complete until bridge pier 1 and after saving beam section 2 by designing requirement erection is first, saving on beam section 2 top board at head and arrange measuring point 5, carrying out measurement and positioning for treating spliced girder section 3;
(3), checking and confirm reference mark: checking when confirming that beam section 3 to be assembled is prefabricated pre-buried for controlling the axial line control point 7 of beam section 3 planimetric position to be assembled and the absolute altitude reference mark 6 for controlling beam section 3 elevation to be assembled on the top board of beam section 3 to be assembled; Equally, there is certain deviation in the reference mark actual coordinate that beam section 3 to be assembled is buried underground when prefabricated and design theory coordinate, adjusts, prepare assembled afterwards by the position, reference mark dividing middle arrow method equally and treat spliced girder section 3;
(4), elevation regulates: the elevation regulating beam section 3 to be assembled according to the measuring point in step (2), placing spirit level on the measuring point saving beam section 2 place specifically at head, the reference mark for the treatment of spliced girder section 3 is measured, until meet design accuracy requirement;
(5), horizontal level regulates: the position of the auxiliary base point 4 set by step (1) regulates the horizontal level of beam section 3 to be assembled, the reference mark utilizing the total powerstation placed on auxiliary base point 4 to treat spliced girder section 3 is specifically measured, until meet design accuracy requirement, then prepare the assembled of next beam section 3 to be assembled;
(6), first joint beam section 2 measuring point 1 is measured: the position of first joint beam section 2 measuring point 1 is measured in auxiliary base point 4 position set by step (1), if the position of measuring point 1 does not change or changes within the scope of design permission, then still save the initial position of beam section 2 measuring point 1 for criterion with head, prepare the assembled of next beam section 3 to be assembled, otherwise save the new position of beam section 2 measuring point 1 for criterion with head, carry out the assembled of next beam section 3 to be assembled by designing requirement;
(7), follow-up assembled: to repeat step (2), (3), (4), (5), (6), continued the assembled of follow-up beam section, completed until all beam sections are assembled.
Axial line control point 7 is two, in the middle of on the top board that axial line control point 7 is positioned at beam section 3 to be assembled, so both conveniently can regulate planimetric position, can ensure again to divide equally the easy to adjust and accuracy of middle arrow method.
Absolute altitude reference mark 6 is for being symmetrically set in the both sides of axial line control point 7, and the absolute altitude reference mark 6 of the every side of axial line control point 7 is two, is beneficial to the adjustment of elevation like this.
Measuring point 5 is at least three, can ensure the accuracy that first joint beam section 2 is measured like this.
In sum, the present invention by selecting auxiliary base point, arrange measuring point, check confirm reference mark, elevation regulates, horizontal level regulates, first joint beam section measuring point is measured and follow-up assembled step completes precast segment bridge erection scene measuring method can ensure bridge shaping after Deformation control and the final linear and internal force of bridge also can meet expection requirement.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
