The present invention relates to an intelligent synchronous grouting control method for shield tunneling construction, which obtains the synchronous grout filling coefficient and the single actual grouting amount of the grouting pump through the unearthed quality of the nth single ring of the shield tunnel and the measurement results of the synchronous grouting amount , and based on the synchronous grout filling coefficient value obtained in the nth ring, the actual grouting amount of a single time, and the unearthed quality of the shield during the construction process of the n+1th ring, recalculate the target synchronous grouting amount, and then control and adjust the grouting pump The number of strokes per unit time; the invention proposes accurate measurement of shield excavation quality and synchronous grouting volume measurement, and accurately adjusts the stroke number of the grouting pump through the control system, realizing the goal of tracking the unearthed quality of shield tunneling Intelligent synchronous grouting control for "zero" loss of formation.
Description
technical field [0001] The invention relates to a civil construction method, in particular to an intelligent synchronous grouting control method and a control system for shield construction. Background technique [0002] The birth of shield tunneling technology has a history of nearly 200 years. It has become the first choice for urban traffic tunnel construction due to its advantages of fast construction speed, low environmental impact, and high degree of mechanization. The synchronous grouting system is an important part of the shield machine. During the excavation process of the shield machine, the synchronous grouting pump uses a certain pressure through the grouting pipe to timely and fully fill the grout into the building voids generated after the segments come out of the shield tail. So as to effectively control the formation deformation and stabilize the tunnel structure. [0003] The early synchronous grouting of shield tunneling took the set grouting pressure as t...
