Abstract

The invention provides a novel double-liquid grouting full hydraulic coupling control system. The novel double-liquid grouting full hydraulic coupling control system comprises an A liquid pipeline and a B liquid pipeline. The A liquid pipeline is sequentially provided with an A liquid stirring tank, an A liquid grouting plunger pump and a first flow sensor. The B liquid pipeline is sequentially provided with a B liquid storage tank, a B liquid variable displacement hydraulic motor drive pump and a second flow sensor. The A liquid pipeline and the B liquid pipeline are combined to a mixing pipeline. The mixing pipeline is provided with a mixer. The A liquid grouting plunger pump is connected with the hydraulic coupling control system. The hydraulic coupling control system is connected with the B liquid variable displacement hydraulic motor drive pump. The second flow sensor is connected with the B liquid variable displacement hydraulic motor drive pump. The device solves the problem about synchronous mixing of double-liquid grouting, the novel double-liquid grouting full hydraulic coupling control system is correspondingly developed, two-phase mixing uniformity is achieved, and accordingly the problem about the mixed grout quality is solved; and the problem that the two-phase gelation time is not easy to control is solved, and accordingly the problem of pipeline blockage risks is solved.

Description

technical field [0001] The invention relates to shield grouting construction, in particular to a novel double-fluid grouting full-hydraulic coupling control system. Background technique [0002] During the construction of the shield, as the shield advances, gaps will be formed between the excavated geology and the segment. In order to fill it tightly in a very short period of time, so that the surrounding rock and soil can be supported in time, effectively prevent the collapse of the soil, and control the settlement of the ground surface, it is necessary to perform grouting operations during the shield tunneling process. [0003] Due to the large difference in permeability coefficient in different strata, synchronous grout is easy to penetrate into the stratum with large permeability coefficient, so the control of grout quality, grouting amount and grouting pressure needs to be fully paid attention to. In order to be able to cope with various soil conditions, The synchronou...
