Description
Technical field
The present invention relates to a kind of ballastless track convex retaining platform construction survey method, especially a kind of CRTS I template formula ballastless track convex retaining platform construction survey method.
Background technology
Be accompanied by the arriving of the upsurge in construction of China Express Railway, traditional ballasted track has reached the limit of supporting capacity under the bullet train action of long-term load, the smooth-going degree variation of track, and the maintenance activity amount strengthens, available maintenance time is fewer and feweri, has seriously hindered the development of high-speed railway.
At present, domestic special line for passenger trains track has all adopted non-fragment orbit basically, and the form of non-fragment orbit mainly contains two kinds: double-block type ballastless track and plate-type ballastless track.Plate-type ballastless track, the CRTS I template formula of mainly classifying non-fragment orbit, CRTS II type plate-type ballastless rail and CRTSIII template formula non-fragment orbit.CRTS I template formula non-fragment orbit has characteristics such as high ride, high stability, high-durability because of it, be widely used at high-speed railway Line for Passenger Transportation construction field.This technology reaches and adjust fixed track guidance tape geometric form position, and for track provides part elasticity, train operation is quick, comfortable to satisfy, safe requirement by backfilling cement emulsified asphalt slurry between concrete bed and track plate.
Convex blocking platform is the important component part of China CRTS I template formula non-fragment orbit, be transmit the track longitudinal force, the track plate is spacing and the main device of location.The height of the construction precision of convex blocking platform directly affects its service behaviour.Japan and China's method of adopting the method for polar coordinate measurement to carry out plane setting-out, measurement of the level are at present carried out the elevation setting-out, i.e. the center that convex blocking platform is established in survey earlier is again according to the center mark installment convex blocking platform template of convex blocking platform.In the curve location,, and often cause boss location mistake because of the projection difference of track centerline on each plane.Simultaneously, because of influencing each other of elevation and plan-position, mistake appears in any one link, just needs to repeat one-shot measurement setting-out work, and efficiency of construction is low.
Summary of the invention
The objective of the invention is at above-mentioned deficiency of the prior art, a kind of plate-type ballastless track convex blocking platform construction survey method is provided.This method adopts the method for freely establishing station polar coordinates setting-out convex blocking platform template, and plane and elevation setting-out are carried out simultaneously, have guaranteed the construction precision of convex blocking platform, have improved efficiency of construction.Special-purpose software can have been avoided the loaded down with trivial details calculating and the generation of artificial error of calculation according to the adjustment amount of the real-time calculation template of survey data.
For achieving the above object, the technical solution adopted for the present invention to solve the technical problems is:
A kind of plate-type ballastless track convex blocking platform construction survey method comprises the steps:
(1) the little prism of fixed installation on mounted boss template;
(2) adopt the position of center line of total powerstation, carry out freely establishing the station according to foundation pile control net at track circuit;
(3) the little prism of installing on the total station survey template carries out setting-out by method of polar coordinates, and survey data is sent in the work computer by wireless module;
(4) the theoretical design load in survey data of returning and the prior input service computer compares, and calculates the deviation of physical location and design attitude by convex blocking platform construction survey software;
(5) according to the adjustment amount that shows on the computer, the boss template position is adjusted, after finishing, adjustment once more the little prism of installing on the template is measured, whether the difference of measurement of comparison value and theoretical value is within the error range that requires, if error does not reach designing requirement, then repeat above-mentioned steps 3,4 and 5 again, if error reaches designing requirement, then adjustment finishes.
Adopt the inventive method, being connected between little prism and the template can be adopted any firm method of attachment, because as long as the relative position between little prism and the template is fixed, a relevant parameter that only needs to revise in the computational process gets final product, to final measurement setting-out precision without any influence.Select for use range accuracy smaller or equal to 2mm+2ppm, angle measurement accuracy is smaller or equal to 1 " total powerstation, the instrument distance of once establishing the station is controlled in the 670m scope, establishing the station residual error can not be greater than 2mm.After total powerstation is once established boss template fine adjusting behind the station and finished, the template that accurate adjustment is good in the whole operating distance is checked, entered next section after the passed examination and carry out boss accurate adjustment construction.
Be overlapped with prism adapter on the boss template in the described step (1), the prism that little prism is inserted on the prism adapter is installed in the jack.
The present invention is the center of little prism design two semicircle boss templates, like this, no matter how template rotate, always the deviation of little prism and line midline remains unchanged, in the setting-out process, only this deviation need be adjusted to design in the allowed band and gets final product.
Described step (5) also includes measurement and has adjusted the little prism of installing on the template that finishes, and whether the difference of measurement of comparison value and theoretical value within the error range that requires, if error does not reach designing requirement, is adjusted again.
Adopt the inventive method, plane and elevation setting-out are carried out simultaneously, have guaranteed the construction precision of convex blocking platform, have improved efficiency of construction.Special-purpose software can have been avoided the loaded down with trivial details calculating and the generation of artificial error of calculation according to the adjustment amount of the real-time calculation template of survey data.
