Description
Technical Field
The invention belongs to the technical field of high-speed rail construction, relates to a contact network completion acceptance technology, and particularly relates to a high-speed rail contact network completion acceptance technology based on a 4C detection technology.
Background
High-speed rails are used as national important infrastructure and popular transportation means, and the position of the high-speed rails in the development of the economic society of China is very important. By the end of 2019, the operating mileage of the high-speed rail in China breaks through 3.5 kilometers, the operating mileage and the speed are the first in the world, and the convenience of high-speed rail traveling is deeply popular with the public. The construction of Chinese high-speed rail is in good order, and a plurality of high-speed rail lines are put into operation every year.
According to the management program of the railway construction project, the high-speed rail must be completed and accepted before being put into use, and can be put into use after being accepted and accepted. The ' acceptance of finished works ' of high-speed railways (iron construction [2012] 107) and ' railway technical management regulations and parts of high-speed railways (iron general technology [2014] 172) have detailed requirements for acceptance of finished works.
Acceptance of completion quality is the last link of construction quality control, is the comprehensive inspection of the quality control result in the construction process, and is the quality control in the aspect of terminal clearance. The running speed of the high-speed rail is 250-350 km/h, and joint debugging joint tests of all professional systems for 2 months are generally carried out before formal opening operation at present, so that the quality of completion acceptance is of great importance to the running safety of a joint debugging joint test comprehensive inspection vehicle and the running safety of high-speed rail line opening operation in future.
Static acceptance of the technical rules for construction of high-speed railway electric traction power supply engineering (total iron construction [2015]47, Q/CR9609-2015) construction units 3 of 9.2.1 should be provided with necessary and qualified detection tools, such as a caliper, a tape measure, a feeler gauge, an insulation resistance measuring instrument, a grounding resistance measuring instrument, a portable contact network measuring instrument, a grounding hanging rod, a safety tool, detection equipment required by spot check and spot test, and the like; and 4, in 9.2.1, the construction unit is required to arrange enough railcars and traffic vehicles according to the engineering units and maintain communication. According to the regulations, the method of checking and accepting the completion of high-speed rail by 18 railroads (groups) is investigated, and the on-line horizontal pushing checking and accepting method of the traditional manual ladder car is still adopted for checking and accepting at present.
Because the high-speed rail motor car is provided with electric power by a contact net erected above the line, in order to suspend a contact line and a catenary above the line, a contact net support is required to be arranged on the line at intervals of 50-60 meters, a supporting device and a positioning device are arranged on the contact net support to suspend the contact line and the catenary, and an integral dropper is arranged between the upper catenary and the lower catenary and the contact line at an interval of 8-12 meters, so that the contact line keeps the design requirement on the rail surface height to meet the running speed of 250-350 km/h of the high-speed rail. Therefore, each contact net support column has a plurality of parts, and the whole suspension strings between every two contact net support columns are also a plurality of, while the contact net generally takes the anchor section as a unit for acceptance, and each anchor section is 1.5 kilometers. High-speed rail is usually hundreds of kilometers when being opened, so the high-speed rail contact net construction completion acceptance workload is extremely large.
The current completion acceptance method comprises the following steps: and the high-speed rail construction unit and the equipment management unit form a combined acceptance group, and the acceptance mode is to adopt a ladder car operation group form for acceptance. According to the safe working rules of high-speed railway contact networks (Total operation of iron [2014] 221), each ladder car is required to be provided with 7 persons, 4 persons push the ladder cars, 2 persons carry out high-altitude operation on the workbench, namely, the construction defects found in the acceptance process are processed, and 1 person serves as a group of responsible persons. Can many terraces simultaneously carry out the flat push and accept to a direction carries out the flat push to another direction and accepts, for example the big high-speed railway of becoming honorable is accepted to big square section, and the acceptance group is accepted from the high-speed railway of graduation station direction to big square high-speed railway station direction flat push and is accepted. Specifically, the tester carries a torque wrench, a slope ruler and a laser measuring instrument to carry out horizontal pushing inspection and acceptance of the support, the positioner and the dropper one by one.
The completion acceptance of the high-speed rail contact network in the prior art mainly has the following defects: 1. the labor intensity is high, each high-speed rail is opened for hundreds of kilometers, at least 50 tens of thousands of parts of a contact network are needed, so that a large amount of manpower and material resources are consumed in the traditional acceptance mode, generally at least 100 persons need to be invested in wind and rain unimpeded all-weather in-situ horizontal push inspection when the high-speed rail is opened, the appearances of hundreds of thousands of parts or even millions of parts need to be inspected one by one, the missing parts are supplemented (the missing parts are not known in advance and are not provided due to the missing part, and the second horizontal push is often needed), the labor intensity of a horizontal push worker is very high in the acceptance stage, the manual shift and the spot addition are generally carried out in a white-black mode in a 5+2 mode and a 996 mode, otherwise, the time node for opening the high-speed rail line by a road bureau cannot be met; 2. the intelligent level is low, the traditional horizontal pushing acceptance mode is purely manually checked by field visual inspection of technical workers, the high-altitude operation time is long, the horizontal pushing inspection is carried out in an original mode by a simple measuring tool, the omission phenomenon is easy to occur, and the intelligent level is not high; 3. the pertinence is not strong, and because actual measurement data is not carried out on the state of the contact network equipment in the opening section in advance, the network can be pulled and pushed horizontally for one time, generally, the network is pushed horizontally from one station to the next station from beginning to end, and the network is pushed horizontally from the starting point to the end point of the opening line, so that the pertinence is not strong, and the efficiency is not high.
