System and Method for Measuring Performance Parameters of Synchronous Grouting in Shield Tunnel

Abstract

Provided is a system for testing performance parameters of slurry for synchronous grouting of a shield tunnel on a construction site. A field data collection terminal is used for being integrated with a data collection module, a data communication module, a data processing and analyzing module and a data management and issuing module, wherein the data collection module, the data communication module, the data processing and analyzing module and the data management and issuing module are connected with one another and communicate with one another. The system further comprises a remote server. The slurry level, density, particle size information, fluidity, consistence, injection intensity and other information of slurry are tested, a data result subjected to calibration processing and analysis is automatically sent to the remote server through network communication technologies according to the preset time and preset mode, and the functions that a data bank stores data and designated persons are informed through mobile messages are achieved; and meanwhile, monitoring control over a field collection computer can be achieved, and faults of the field collection computer can be cleared up in time conveniently. By means of the system, remote automatic testing on the performance parameters of slurry for synchronous grouting of the shield tunnel on the construction site is achieved, the efficiency and accuracy of testing on the performance parameters of slurry are improved, and great convenience is brought to constructors to master the slurry performance.

Description

technical field [0001] The invention belongs to the field of tunnels and underground engineering, and relates to a technique for measuring performance parameters of synchronous grouting grout on a shield construction site. Background technique [0002] At present, the scale of urban rail transit construction in my country is large, and the shield tunneling method has good safety and wide application range, and more than 100 kilometers of shield tunnels are built every year. During the shield construction process, after the shield tail is separated from the segment, on the basis of the original shield tail gap, a new gap is added on the back of the segment due to the forward advancement of the shield shell. If the gap is not backfilled in time, it will inevitably cause formation deformation, and then have a destructive effect on adjacent underground structures. For example, the foundation of the building is tilted and cracked, various pipelines in the ground are cracked or b...

Problems solved by technology

Obviously, the traditional laboratory measurement method has disadvantages such as cumbersome operation process, heavy workload, long measurement time, large accidental measurement error, and inaccurate measurement, especially for the determination of coagulation time. Long, manual operation error is large
