Abstract
The invention relates to a deformation monitoring method for the existing railway line, which comprises the following steps: (1) selecting right types of total stations and prisms; (2) carrying out point distribution on a line required to be measured, and installing the prism at each measuring point; (3) through site survey, burying a sufficient quantity of datum points and station points convenient to observe the prisms; (4) carrying out real-time measurement on the prisms through the total stations arranged at the station points so as to obtain the three-dimensional coordinate of each prism; and (5) through comparing the three-dimensional coordinates of the prism during different time periods, calculating the deformation value and change rate of the line during the period. The invention is a deformation monitoring method for the existing railway line, which is scientific in design and easy to implement. By using the method disclosed by the invention, the data of settlement and horizontal displacement of the existing railway line in operation can be accurately acquired under the premise of not affecting the operation of the existing line, thereby guaranteeing the necessary monitoring frequency; and the acquired data represents the deformation of the line during all time periods, and finally, the purpose of carrying out real-time monitoring on the existing railway line and guaranteeing the safe operation of trains is achieved.
Description
Technical field
The present invention relates to railway monitoring method field, especially a kind of railway existing line deformation monitoring method.
Background technology
Carry out engineering construction or railway line when passing frequent regional of geology activity at the periphery of existing railway line, the probability of rail generation sedimentation and displacement is very big, in case the deformation values of rail surpasses warning value, the operation security of train will be affected.In order to guarantee the safe operation of train, need monitor the rail distortion of existing railway line.At present, mainly contain following several kinds of monitoring methods: 1, static level method: it does not influence operation, but can only carry out settlement measurement; Can not carry out horizontal shift measures; And equipment receives the influence of surrounding enviroment very big, and the monitoring element volume is bigger, can not directly measure the sleeper distortion; The reference point of static level can not be arranged on the stabilized zone far away apart from circuit, and error is bigger.2, traditional water locating tab assembly: its precision is higher, but Measuring Time and frequency limited system, and can only carry out settlement measurement, can not carry out horizontal shift and measure.In addition, need personnel to get into operational area work, influence the operation of existing line.3, bury sedimentation pier or displacement monitoring mark in the roadbed underground: it is big that it buries difficulty underground, and measuring error is big.
In sum, more than three kinds of monitoring methods commonly used cut both ways, its measuring result error is all bigger, and all can not satisfy under the prerequisite that does not influence railway operation, both sedimentation was measured to rail, again the rail horizontal shift was carried out the monitoring requirement of data acquisition.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide a kind of reasonable in design, measuring process is simple and convenient, can measure the sedimentation and the horizontal shift of existing line rail, and measurement result railway existing line deformation monitoring method accurately.
The present invention solves its technical matters and realizes through following technical scheme:
A kind of railway existing line deformation monitoring method is characterized in that: may further comprise the steps:
(1). select the total powerstation and the prism of suitable types;
(2). the circuit to need are measured is layouted, and on each measurement point, prism is installed;
(3). reconnaissance trip is buried the reference point and the survey station point of being convenient to observe prism of sufficient amount underground;
(4). the total powerstation through being arranged on the survey station point is measured prism in real time, obtains the three-dimensional coordinate of each prism;
(5). through the three-dimensional coordinate of comparison prism, can calculate deformation values and the rate of change of this measuring point of circuit in this period in the different periods.
And; Described prism comprises little prism body and a L shaped bracing frame; This L shaped bracing frame is made up of vertical riser and horizonal base plate, and little prism body is installed in through screw on the vertical riser of L shaped bracing frame, on the horizonal base plate of L shaped bracing frame, makes vertical mounting hole.
And; The said installation prism of layouting of step (2) is: on the concrete sleeper of each measurement point, hole; The horizonal base plate of the L shaped bracing frame of prism is installed on the concrete sleeper, rotates prism and make it put direction, with bar planting glue the L shaped bracing frame of prism is fixed then towards survey station.
And reference point described in the step (3) and survey station point all adopt forces centralising device.
Advantage of the present invention and beneficial effect are:
1, this monitoring method goes out the three-dimensional coordinate of different periods of each measurement point of sleeper through total station survey; Be the settling amount and the horizontal displacement of sleeper through the variable quantity that calculates; Thereby can monitor the distortion of sleeper; And then the distortion of reflection circuit, supervisory function bit is played in operation to railway security.
2, adopt this monitoring method not only can obtain the deflection of sleeper, can also obtain the rate of change of sleeper, and the measurement result precision is high.
3, simple and convenient, the quickness and high efficiency of this observation process; After the prism installation, needn't get into operational area can monitor sleeper in real time, has effectively guaranteed the personal safety of survey crew; Do not influence railway operation, and can realize the automatic monitoring of full time period.
4, the prism among the present invention is installed in concrete sleeper through L shaped bracing frame; This bracing frame adopts that screw is fastening to be installed on the sleeper with the gluing double fixed mode of bar planting, this structure guaranteed prism do not receive ambient environment vibrations influence, improved the accuracy of measurement result.
5, the present invention is that a kind of design science, enforcement are easy to railway existing line deformation monitoring method; This method can be under the prerequisite that does not influence the existing line operation; Exact acquisition is carried out in the sedimentation of the existing operating line of railway and the data of horizontal shift; Guarantee necessary monitoring frequency, and the distortion of the data represented full time period of circuit of gathering, finally reach the purpose of the railway existing line being monitored, guaranteed the train safe operation in real time.
Description of drawings
Fig. 1 is the scheme of installation of prism among the present invention.
