• Reliability
1. Unique data audit, three party confirmation
System with third party confirm start stretching function and technicians confirm tension data is correct or not, are arranged on two ends of the jack workers, installed after the click ready, as long as there is not ready cannot start stretching process, prevent the misoperation of wounding.
2. Unique jack protection
The same set of systems support a variety of models of the jack work, simply to carry out a simple change of the jack operation, and must be replaced by a fully correct system before the system can be started.
• Precise control
High precision pressure sensor and displacement sensor are used in the system
Pressure sensor ：Measurement accuracy is less than 1%F.S
Displacement sensor ： Measurement accuracy ±0.1mm
Using high precision sensor, the application of pre stress and elongation balance control in tension construction
• Practicability
Complete beam type library function, the beam type parameter setting is simple and flexible
Technical personnel will be used to all of the prestressed beam type, beam length, steel beam number and other basic parameters are set up, the establishment of the beam type library, can be repeated calls.
•Convenient tension task pre setting function
The set of beam type respectively arranged tension and elongation value Zhang pull parameters, parameters set up a simple, convenient and tension parameter setting of memory function, maximum limit reduced duplication of data input, to avoid duplication of input of human error.
After the basic parameters of the bridge are set up, according to the independent beam number and the tension parameter of each piece of beam, the tension task database is established, and the tension task can be completed in one time.
•Convenience
• One Key operation
Through a set of task library, the transfer of a pulling tasks,pull according to sequence operation, a key to start automatically the process, after the completion of the pulling tasks with red tips, effectively avoid misoperation.
Photo record
The system has the operation personnel and supervision personnel live picture archiving function.
In tensioning process, the system has the functions of automatic holding, automatic filling, automatic return and stop, and the whole tensioning process does not need manual intervention.
• Real Time Monitor and Record Data
The tension process is recorded in real time and automatically generated tension curve, which is accurate, intuitive, convenient to check and review, effectively improve the construction quality, and at the same time give consideration to the convenience of the construction.
• Automatically Generate Print Reports
Automatic generation of tensile records, real and complete, reduce the manual input and calculation, improve the efficiency of the work. According to the needs, can be set to multiple template output, making the output statements more flexible and diverse.

Comparison Between the Intelligent Pressure Grouting Trolley with the Traditional Grouting Equipment
Functional Features of Intelligent Pressure Grouting Trolley
System integration is high
System will automatically feed, feeding system, automatic weighing system, high-speed pulping machine, low slurry storage tank, pressure pump, automatic packing system integration in one, the scene using only the pulp inlet pipe and back grouting pipe and prestressed pipe butt, can press grouting construction. We strive to operate simple, easy to use, complex engineering standards.
Automatic weighing function
System according to the proportion of automatic water, additives, cement and automatic weighing, to ensure that the water cement ratio is in line with the requirements.
Standard mixing time
The system can set the mixing time, so as to regulate the mixing process, so that it can meet the requirements of the national standard.
High speed pulping
High speed pulping machine speed is 1440r/min, blade line speed >18m/s, in the setting of the mixing time, the water and cement fully mixing, to achieve the construction requirements.
Automatic discharge
After pulping is completed, the system automatically detects the capacity of the low speed pulping barrel. If the machine can be put in the pulp automatically, the automatic closing of the pulp is finished.
Large circulating pressure, air exhaust
Support single pore pressure slurry and double channel large circulation pressure pulp, large circulation pressure slurry is through the slurry in the continuous circulation of the pipeline, the channel of the air is completely discharged, and can bring out the residual impurities in the channel
Accurate detection, automatic pressure protection
Closed pulp out mouth, pulp outlet pressure reaches 0.7 MPa, the system will automatically enter the state of pressure keeping, automatically adjusting pressure pump speed, into the slurry inlet and a slurry outlet pressure for a long time to maintain 0.5 ~ 0.7MPa, ensure grouting compacting.
Data storage function
The system can automatically store the water cement ratio, grouting pressure, slurry time isobaric data, convenient query and analysis.
