Description
Technical field
The utility model relates to a kind of grouting simulation test platform, especially relates to a kind of shield-tunneling construction synchronous grouting simulation test platform.
Background technology
Nowadays, shield method has become the main construction method of constructing metro tunnel.In Analysis on Shield Tunnel Driven Process, the deformation factor causing shield tunnel to deform is a lot, but mainly because excavation causes soil layer lose thus cause surface settlement.Thus, in shield tunneling process, carry out synchronous grouting behind shaft or drift lining in time, fully, effectively can reduce soil layer loss, and whether slip casting is abundant, whether slurries can produce the factors such as loss in process of setting, all can have a direct impact soil layer additional deformation.For this reason, domestic and international many experts and scholars have carried out the correlative study of grouting behind shaft or drift lining aspect with methods such as theory analysis, field measurement, model experiment, numerical simulations.
Shield-tunneling construction causes the main cause of ground settlement to be larger than the external diameter of section of jurisdiction ring due to shield structure external diameter and structure void (i.e. shield tail space) that is that formed, because shield tail space in a period of time after disengaging shield machine shield tail is close to non-matted state, along with the increase of surrounding soil range of disturbance, the distortion in shield tail space or partial collapse directly affect the degree of ground settlement, and the best method addressed this problem is grouting behind shaft or drift lining.During practice of construction, first by the method for field experiment, mud can be injected shield machine shield tail, and then the effect of noted mud control surface settlement is analyzed.But present stage, different mud is controlled to the research of surface settlement effect, the overwhelming majority is that the mode choosing experimental section by scene on constructed shield tunnel is studied, this research method Meteorological is larger, risk is also larger, and only can to the physical property of mud itself, chemical property and mechanical property carry out detecting (namely to the viscosity of mud, gel force, degree of mobilization, gel times etc. detect) and the mud cake quality situation after consolidation and sclerosis is detected, then make this mud and whether can play effect needed for engineering, but this detection method does not consider shield-tunneling construction ground geology, the complexity of soil property, and the interaction of the soil body and mud, thus on-the-spot practice of construction situation can not be reflected well, there is certain limitation, main cause is the real effect that mud control earth's surface is out of shape and the physico-mechanical properties of mud of getting along well itself is directly proportional.
