Description
Technical field
The present invention relates to a kind of unballasted track bed plate elevation Quick Test Vehicle.
Background technology
The substructure of ballastless track of high-speed railway---bed plate construction is one of most important link of railway roadbed construction.In the non-fragment orbit construction of CRTS II template structure, the bed plate Construction quality control is very big to the influence of later stage CA mortar construction, and especially the absolute altitude of bed plate upper surface is controlled, and has a strong impact on the thickness of CA screed.According to design specifications, CA screed THICKNESS CONTROL is between 2-4cm, because track plate bottom surface is non-smooth surface, when the polarization of bed plate absolute altitude, often cause CA screed effective thickness less than 2cm, this situation once caused a large amount of doing over again in high speed railway engineerings such as Beijing-Shanghai, Beijing-to-Shijiazhuang, Shi Wu, bring several direct losses of ten million.If have a mind to the absolute altitude of bed plate is reduced, guarantee the thickness of CA screed, can cause the waste of a large amount of CA mortars again.
During non-fragment orbit was constructed at home at present, the bed plate construction all adopted the method for artificial measurement of the level to detect elevation, and workload is very big, needs a lot of survey crews, and efficient is lower, the cost height.
At present also there is not special measureing equipment to be fit to this purposes both at home and abroad, after being adapted at theing cement solidifies, the method that level detects measures, the elimination of vertical error can only be made up with milling or other people construction method, can't carry out process control in the bed plate work progress, this method must cause the generation of the cost of doing over again.
Summary of the invention
Its purpose of the present invention just is to provide a kind of unballasted track bed plate elevation Quick Test Vehicle, has solved the problem of quick measurement bed plate upper surface vertical error.Have in-site measurement, calculating, demonstration, memory function, fast, instant detect, immediate assessment, for the non-fragment orbit practice of construction provides a cover special quality control apparatus and means, improved efficiency of construction, reduce construction cost, improved the construction technology level of non-fragment orbit.
The technical scheme that realizes above-mentioned purpose and take, comprise the fast pulley across the bed plate both sides, fast pulley is provided with vehicle frame, and described vehicle frame is provided with prism, obliquity sensor and 4 sonar sensors, and described prism, obliquity sensor and sonar sensor are connected with total powerstation.
Beneficial effect
Compared with prior art the present invention has the following advantages.
1, can be in bed plate be poured into a mould the receipts face process of operation, before cement concrete solidifies, measure the vertical error of bed plate upper surface fast, for the constructor provides visual accurate foundation, by the deviation of repairing timely, the receipts face is made elevation up, with the control of absolute altitude be placed on solidify before, find that the absolute altitude error is too big when avoiding by the time track slab precision adjustment, need carry out the measure of remedying of milling to bed plate.The present invention also can be used in after the bed plate construction, before the road bed board accurate adjustment, the absolute altitude of bed plate is rechecked, is generally investigated, and understands the elevation situation of change;
2, the present invention integrates total powerstation automatic measurement technology, non-contact detecting technology, non-fragment orbit design document, based on the computer software technology of digital measurement, form the software systems that a cover uses light and handy hardware easily and has in-site measurement, calculating, demonstration, memory function, instant detection, immediate assessment fast,, for the non-fragment orbit practice of construction provides a cover special quality control apparatus and means, improve the construction technology level of efficiency of construction, reduction construction cost, raising non-fragment orbit.
