Description
Technical Field

Background
In the fields of civil engineering and traffic engineering, the soft sandy soil foundation usually has the characteristics of insufficient bearing capacity, large deformation after construction and the like, so that how to safely, economically, quickly and reliably construct engineering on a soft sandy soil site becomes a technical problem.
The grouting reinforcement method is to inject chemical grout into soil and solidify the chemical grout with the soil, thereby achieving the purpose of reinforcing the foundation or improving the seepage-proofing capability. The grouting method has the advantages of simple construction, high construction speed, low construction cost, obvious effect, reliable technology, wide application range and the like, thereby being widely applied to seepage-proofing reinforcement engineering of foundations, dams, road beds, side slopes and the like. However, the sand foundation has small porosity and poor permeability, so that the grouting radius of the traditional static grouting technology is small in grouting construction, and therefore grout cannot be injected into the sand. The vibration grouting mechanism is that the sand is excited to liquefy through mechanical vibration, the shear strength of the sand foundation is reduced, and the permeability of the sand is improved, so that the sand foundation has grouting performance and grouting radius is enlarged.
However, at present, for general grouting improvement engineering, two grouting methods are generally adopted: firstly, during grouting, the idea of 'injecting more as much as possible' is taken as a guide, and a lower-end deformation monitoring means is adopted, so that deformation response is not timely, excessive settlement or deviation is caused, more serious secondary diseases are generated, and the method is not economical; secondly, the serious consequences caused by construction deformation are unscrupulous, the grouting process is controlled too strictly, the observation and evaluation time of construction influence is too long, the construction period is prolonged, and the progress is pursued at the cost of sacrificing the grouting amount under the condition that the construction period gradually tightens, so that the grouting quality cannot meet the requirements.
Therefore, for soft sandy soil foundations, the vibration grouting machine needs to be optimized by combining site features, the informatization and intelligentization degrees of grouting engineering are improved, a series of improvements and promotion of the existing vibration grouting technology are realized, and the liquefaction sandy soil site foundation reinforcement engineering can be served more economically, suitably, stably and efficiently.
