The invention provides an indoor simulation device for road base or roadbed grouting reinforcement effects, which comprises a gas compressor, a slurry storage tank and a model box, wherein the gas compressor is communicated with the inner part of the slurry storage tank through a gas compression pipe; the upper part of the slurry storage tank is provided with a slurry grouting port; the bottom part of the slurry storage tank is provided with a slurry outlet; the slurry outlet is connected with the model box via a slurry grouting pipe; through adjusting a longitudinal baffle and a transverse baffle in the model box, the size of a shaping room can be adjusted, the effective size of a slurry grouting test piece is further adjusted, void with the same size of a different road base or a roadbed can be simulated. When the longitudinal baffle and the transverse baffle are removed, the initial height of an active plate is adjusted, and the void of a different height can be simulated. In the case of grouting completion and demolding, gas filling and pressurization in a sealed gas-filled cavity are carried out through the gas compressor, the active plate rises, the test piece is ejected for demolding, and the operation is simple and convenient.
Description
technical field [0001] The invention belongs to the field of road engineering, and relates to a simulation device, in particular to an indoor simulation device for the reinforcement effect of road base or subgrade grouting. Background technique [0002] Under the action of traffic load and natural environment, the road base or subgrade is prone to damages such as erosion, hollowing out and insufficient strength. Grouting reinforcement is an effective way to deal with these diseases. However, the on-site grouting construction process has strong concealment and uncertainty, and it is difficult to observe the flow and distribution of grout inside the road, which brings many difficulties to grouting design and actual construction. Indoor simulation test is a common method to study the effect of grouting reinforcement, which can simulate the effect of on-site grouting at a relatively low cost and provide reference for practical engineering applications. Most of the existing grou...
