Description
Technical Field
The invention relates to the technical field of geotechnical engineering, in particular to a geotechnical engineering foundation pit supporting structure.
Background
Geotechnical engineering is a new technical system established in civil engineering practice in 60's of the 20 th century in the countries of the Europe and the America. Geotechnical engineering is to solve the problems of rock and soil engineering, including foundation and foundation, slope, underground engineering and the like, and is used as a research object of the geotechnical engineering. With the prosperity and development of the economy of China, various building projects are pulled out like bamboo shoots in spring after rain. Among various civil engineering, geotechnical engineering plays an important role.
Geotechnical engineering is systematic work which is carried out by comprehensively renovating and utilizing geotechnical bodies by using various exploration and test technologies on the theoretical basis of soil mechanics, rock mechanics and engineering geology. This discipline is known in foreign countries in some countries and regions as "geoengineering", "soil engineering" or "soil engineering". Geotechnical engineering is an important component of civil engineering. The statistics of data includes investigation, design, test, construction and monitoring of geotechnical engineering, and relates to the whole engineering construction process. The method has very important significance in various constructions such as houses, municipal works, energy sources, water conservancy projects, roads, shipping projects, mines, national defense and the like.
When the building construction is carried out, a deeper foundation pit is usually dug on a rock-soil layer to build a building foundation, and the rock-soil deep foundation pits need to be fixedly supported by using a supporting structure to prevent the rock-soil deep foundation pits from collapsing and deforming. In the construction of deep foundation pit supporting engineering, the cement mixing amount of the deep mixing pile is often insufficient, so that the supporting strength of cement soil can be influenced, and further the cement soil is cracked.
