Description of drawings:
Combine the description of its accompanying drawing through following embodiment, can further understand and use novel purpose, specific structural features and advantage in fact the utility model.Wherein, accompanying drawing is:
Fig. 1 is the overall flow sketch map of the utility model bridge jacking supervising device;
The specific embodiment:
Below in conjunction with the instance among the figure the utility model is done further to describe.
No matter jacking or translation, whole operation control all is in central control room, to accomplish, therefore, operating personnel should be able to monitor the various parameters of works transition process at central control room, and control procedure is adjusted in real time, reach the purpose of dynamic optimization.In order to accomplish above-mentioned purpose, on the master control computer monitoring software has been installed.Under Windows 2000 operating systems, adopt three-dimensional force control configuration software to work out monitoring software, the structure of this monitoring software is as shown in Figure 1.Monitoring software mainly is made up of task management module and interface management module two large divisions.
Task management module real-time comprises hardware management, communication, monitoring and data in real time, and hardware management module is mainly carried out self-test to various hardware before use, guarantees the hardware operate as normal; The communication module real-time is the strongest, and serial communication is here accomplished between master control computer and the PLC; Real-time monitoring module mainly is that each cylinder pressure and displacement are carried out the dynamic decision optimal control, shows in real time, also can observe with the form of performance graph simultaneously, is convenient to the overall process of monitor pressures and change in displacement; Data processing module can storage system initiation parameter and real-time data base, simultaneously also can printing data report form.
The function of man-machine interaction is mainly accomplished at the interface of monitoring system.Parameter is provided with the setting that the interface provides the preceding controlling parameter of system's operation; Comprise pumping plant selection, displacement transducer grouping, hydraulic cylinder is related with displacement transducer and synchronization accuracy etc.; These parameters are provided with all and can be kept in the engineering; If do not change when use next time, these parameters needn't be provided with again.Weigh, jacking, translation interface mainly be used for showing pressure and displacement, shows with the form of data, if want to observe the real-time change trend of pressure and displacement, need switch to the performance graph interface to get final product.Single cylinder debugging interface all can be called in any process, carries out man-machine interaction, adjusts the up-down of selected cylinder pressure.
Beam key point synchronously falls
Maximum difficult point in dropping process is that hydraulic power unit is being opened in a flash, and the jack that connects pumping plant all is to carry lighter opening earlier, causes the jack heavy duty of original pad heavy more like this, and underloading is light more, and this causes fatal danger to the whereabouts.The protective valve (balanced protection valve) that all carries that the applicant is provided with at pumping plant valve piece place has solved this crucial difficult point.When the oil cylinder that all carries protective valve when a plurality of bands supported a heavy duty simultaneously, when needs descended synchronously, the oil cylinder that load is bigger can be opened earlier.
The monitoring of this programme refers in the jacking process monitoring carried out for the whole attitude that guarantees bridge to comprise translation, rotation and the lateral attitude monitoring of structure that monitoring is in the jacking overall process.
The bridge jacking process is a dynamic process, and along with the lifting of superstructure, bigger variation can take place for the along track bias of beam, plate-girder gap etc.A whole set of monitoring system to be set for this reason, and will set necessary early warning value and limiting value, so that attitude data is fed back to construction loading process.
Monitoring position and monitoring content:
(1) foundation settlement survey: the foundation settlement survey system is set reacts cushion cap sedimentation situation, in time make relative measures.
(2) bridge floor absolute altitude observation: bridge floor elevation observation point is used for calculating the actual top lifting height of each bridge pier.Bridge floor absolute altitude observation point is set makes the actual top lifting height of every bridge pier define foundation, the bridge floor absolute altitude is effectively controlled to make jacking put in place afterwards.
(3) bent cap bottom surface level measurement: it is replenishing of control of bridge floor absolute altitude and measurement, and auxiliary jacking operation foundation is provided
(4) bent cap length travel observation
For observation to bent cap length travel in the jacking process and column verticality, eject vertical projecting line at the outer column lateral surface with the line of ink marker, the line of ink marker must be crossed below the cut surface by bullet, at shot of the top of vertical line of ink marker suspension.Whether the length travel of relatively judging bent cap and bent cap through the plumb bob line and the line of ink marker tilt.
(5) observation of support system
Through observation, can in time grasp the deflection that the stressed of support system and distortion situation in time take measures to control support system, construction is carried out under the controlled environment of safety.
Monitoring scheme is implemented
(1) monitoring is prepared
Mainly be to arrange measuring point.
(2) monitoring before the construction
It mainly is the initial value of each monitoring point being obtained each item monitoring parameter.Like observation point coordinate situation, absolute altitude etc.
(3) integral jacking monitoring
Comprise jacking, the monitoring of the processes such as beam that support, fall.The monitoring content mainly comprises the whole attitude monitoring, ess-strain monitoring etc. of displacement monitoring, bridge.
Monitoring organization arrangement
Monitoring plan should be coordinated with the Construction Plan of jacking mutually, and can in implementation process, improve, and its monitoring result should in time feed back to on-the-spot commander in chief.
Press following principle arrangement during monitoring:
1. the monitoring plan of formulating in advance;
2. crucial construction link carries out necessary monitoring;
When 3. special operation condition takes place, replenish monitoring;
4. monitoring result occurs when unusual, replenishes monitoring;
That is, the monitoring of the technical scheme of the utility model refers in the jacking process monitoring carried out for the whole attitude that guarantees bridge to comprise translation, rotation and the inclination of structure.Monitoring is in the jacking overall process.Monitoring position and monitoring content comprise: the observation of (1) bridge floor absolute altitude; (2) monitoring of box-beam structure deformation observation (3) jacking load; (4) jacking stroke observation;
Monitoring system: no matter jacking or translation; Whole operation control all is in central control room, to accomplish, and therefore, operating personnel should be able to monitor the various parameters of works transition process at central control room; And control procedure adjusted in real time, reach the purpose of dynamic optimization.In order to accomplish above-mentioned purpose, on the master control computer monitoring software has been installed.Under Windows 2000 operating systems, adopt three-dimensional force control configuration software to work out monitoring software.Monitoring software mainly is made up of task management module and interface management module two large divisions.
