Description

Deep foundation pit protection system

Technical Field

The utility model relates to the technical field of foundation pit protection, in particular to a deep foundation pit protection system.

Background

The foundation pit is a soil pit excavated at the design position of the foundation according to the elevation of the foundation and the plane size of the foundation. Before excavation, an excavation scheme is determined according to geological and hydrological data and the conditions of buildings nearby the site, and waterproof drainage work is performed. The person who is not excavated can use the method of putting the side slope to stabilize the earth slope, and the size of the slope is determined according to the relevant construction regulations. When a deeper foundation pit and a building adjacent to the deeper foundation pit are excavated, a foundation pit wall supporting method, a concrete-sprayed wall protecting method and a large foundation pit are used, and even an underground continuous wall and a columnar column type bored pile are used for interlocking, so that an outer soil layer is prevented from collapsing; for those who have no influence on nearby buildings, the underground water level can be reduced by a well point method, and slope releasing open cut is adopted; the construction quality of the deep foundation pit is the function of the foundation stone in the building engineering and must be done. When the novel safety education method is well done, safety must be paid attention, a lot of casualties occur every year, and when new workers enter the field, three-level safety education is in place; the shift safety technology is in place; the supervision, inspection, re-education and assessment work in place in the construction process; the work is summarized and improved after work.

Because most existing foundation pits are deep in depth, due protective measures are lacked at the periphery or the protective measures are simple and crude, the phenomena of foot loss, falling and the like can be caused, dangers are caused to a human body, and the simple guardrail is often overturned due to the conditions of large wind, unstable placement and the like when in use.
