Description

Special foundation ditch protective structure of soft foundation building

Technical Field

The invention relates to the technical field of foundation pit protection, in particular to a foundation pit protection structure special for a soft foundation building.

Background

The definition of the highway industry standard in China on the soft soil foundation refers to a soft soil layer with low strength and high compression amount, and most of the soft soil layer contains certain organic substances. Because the soft soil has low strength and large sinking and hiding amount, great harm is often brought to road engineering, and if the treatment is improper, great influence is caused to the construction and the use of a road. 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 persons with low excavation depth can use the method of putting side slope to make the earth slope stable, and the size of the slope is determined according to the relevant construction project. 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; in cold regions, natural cold freezing method can be adopted for excavation and the like.

In the prior art, a supporting plate is generally adopted for protecting a foundation pit, so that the stability is not strong, and only the operation with fixed height can be performed; because the angles of the foundation pits are different, the foundation pit protection mechanism in the prior art cannot adjust the angles, and the practicability is not strong; moisture that contains in the foundation ditch can exert an influence to the foundation ditch, and prior art does not be provided with the function of drainage to influence the stability of foundation ditch, produce the potential safety hazard.
