Problems solved by technology

[0004] However, at present, for general grouting renovation projects, two grouting methods are usually used: one is to use "as much injection as possible" as the guiding ideology during grouting, and use relatively low-end deformation monitoring methods, resulting in untimely deformation response and resulting in excessive deformation. Subsidence or offset will cause more serious secondary damage and is very uneconomical; second, fear of serious consequences caused by construction deformation, too strict control over the grouting process, too long time for observation and evaluation of construction impact, resulting in delays in the construction period, In the case of gradually tightening the construction period, the progress was caught up at the expense of the amount of grouting, resulting in the grouting quality not meeting the requirements

Description

technical field [0001] The invention relates to an informationized intelligent vibration grouting machine with adjustable vibration and controllable direction, which belongs to the technical field of engineering construction. Background technique [0002] In the fields of civil engineering and traffic engineering, soft sandy soil foundations usually have the characteristics of insufficient bearing capacity and large post-construction deformation, making it a technical problem to build projects on soft sandy soil sites safely, economically, quickly and reliably. [0003] The grouting reinforcement method is to inject chemical grout into the soil and consolidate it with the soil, so as to achieve the purpose of strengthening the foundation or improving the anti-seepage ability. The grouting method has the advantages of simple construction, fast construction speed, low construction cost, remarkable effect, reliable technology and wide application range, so it is widely used in ...
