The soft pipe is connected between the water tank and the pipe-jacking machine, one end of the soft pipe is connected with the water pipe, and the other end of the soft pipe is sealed and fixed on a machine head of the pipe-jacking machine. A pressure sensor serving as standard pressure is connected with a portion of the soft pipe, one end of the soft pipe connected with the machine head is connected with a pressure sensor, and signal output ends of the pressure sensors are connected with the intelligent digital indicator through the signal cable. The device has the advantages of automatically monitoring elevation errors and change trends of the pipe-jacking machine in real time, adjusting positions of the pipe-jacking machine according to monitoring conditions in real time, ensuring the pipe-jacking machine to jack according to the designed elevation, achieving automatic measurement, and improving efficiency of pipe-jacking construction and the like.
Description
[technical field]
The utility model relates to the device of measuring elevation by communicating pipe and hydrostatic, specifically a kind of long-distance pipe jacking elevation self-operated measuring unit.
[background technology]
High range monitoring and the measuring method of pipe-jacking project mainly contain spirit-leveling instrument method, total powerstation method, laser transit method etc. at present.These methods are, the reason such as measurement range limited low owing to complex operation, time and effort consuming and measuring accuracy often, can not satisfy the measurement demand of the various complicated pipe-jacking projects such as long distance, extra long distance, Curve Pipe Jacking.In jacking construction now, just lacking a kind of Real Time Monitoring means to the change of push bench head height journey.In sum, the automatic method and apparatus of measuring of long-distance pipe jacking elevation is significant to the smooth enforcement of pipe-jacking project.
[summary of the invention]
In order to solve above-mentioned problem of the prior art and defective, the utility model provides a kind of precision higher, measures more easily long-distance pipe jacking elevation self-operated measuring unit.
For achieving the above object, design a kind of long-distance pipe jacking elevation self-operated measuring unit, comprise push bench, water tank, flexible pipe, pressure transducer, signal cable, cable plug-in module, automatic exhaust steam valve, self-sealing joint, can only digital displaying meter, between described water tank and push bench, connect a flexible pipe, flexible pipe one end and water tank UNICOM, other end sealing also is fixed on the push bench head, place on flexible pipe connects the pressure transducer as datum pressure, connect a pressure transducer on flexible pipe one end that is connected with head, the signal output part of described pressure transducer all is connected with intelligent digital displaying meter by signal cable.
Described flexible pipe is formed by connecting by self-sealing joint by some short tubes.
Described signal cable is pegged graft by cable plug-in module by some shorter signal cables and is formed.
Described flexible pipe is provided with several automatic exhaust steam valves.
Described automatic exhaust steam valve is equidistantly arranged.
Be higher than the push bench position on the described water tank location vertical direction.
The utility model has the advantage of: but the height variation of real-time automatic monitoring push bench and variation tendency; Immediately adjust the attitude of push bench according to the monitoring situation, guarantee that push bench is according to the design altitude jacking; Realize automatic measurement, save in the past required time and the manpower of measuring method, improve the efficient of jacking construction.
[description of drawings]
Fig. 1 is structural representation of the present utility model;
Pressure transducer 4. flexible pipes 5. automatic exhaust steam valves 6. intelligent digital displaying meters 7. signal cables 8. self-sealing joints 9. cable plug-in modules of 1. water tanks, 2. datum pressure sensors, 3. push bench among the figure.
[embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer, the utility model is further elaborated.Production equipment among the application all is the common equipment of this area, should be appreciated that specific embodiment described herein only in order to explaining the utility model, and is not used in restriction the utility model.
As shown in Figure 1, comprise push bench, water tank, flexible pipe, pressure transducer, signal cable, cable plug-in module, automatic exhaust steam valve, self-sealing joint, can only digital displaying meter, connect a flexible pipe between described water tank and the push bench, be higher than the push bench position on the water tank location vertical direction, flexible pipe one end and water tank UNICOM, other end sealing also is fixed on the push bench head, place on flexible pipe connects the pressure transducer as datum pressure, flexible pipe is provided with several automatic exhaust steam valves, connect a push bench pressure transducer on flexible pipe one end that is connected with head, the signal output part of described pressure transducer all is connected with intelligent digital displaying meter by signal cable.Flexible pipe is formed by connecting by self-sealing joint by some short tubes.Signal cable is pegged graft by cable plug-in module by some shorter signal cables and is formed.Automatic exhaust steam valve is equidistantly arranged.
Method of operating
Water tank as for certain altitude, is formed certain difference in height with datum pressure sensor and push bench pressure transducer, guarantee that two pressure transducers all can work.
Datum pressure sensor and head pressure sensor are fixed on respectively reference position H and push bench measuring position h in the push pipe well in operation.
Water tank, datum pressure sensor, head pressure sensor are by soft pipe connection, and water tank is filled with water so that be full of water in the flexible pipe.
Intelligent digital displaying meter is placed in the push bench, connect two pressure transducers by signal cable, receive two pressure transducer pressure datas, and calculate reference position hydraulic pressure height H and push pipe head measuring position hydraulic pressure height h, and then in the discrepancy in elevation that shows two pressure transducers of screen display
△ h (△ h=h-H) numerical value.
As shown in the figure, in the long-distance pipe jacking, automatic exhaust steam valve is installed to get rid of unnecessary gas in the flexible pipe every a segment distance at flexible pipe.
Water can not run off when the quick change self-sealing joint of installing on the flexible pipe disconnected; But the cable connector of installing on the telecommunication cable is fast insert-pull all, so that the disconnecting when follow-up tube coupling is installed.
By the discrepancy in elevation data that intelligent digital displaying meter shows, operating personnel can read in real time push bench head height journey and change, and then in time adjust the head attitude, make head by the design altitude jacking.
