Problems solved by technology
The enclosure structure has high rigidity and strong deformation resistance. However, the 900mm wide-cap steel sheet pile and H-shaped steel are welded to form a whole, and the structural geometry is large. It has a great impact on the surrounding environment. In addition, due to the overall welding, it is difficult to separate the wide-hat steel sheet pile from the H-shaped steel

The invention relates to the technical field of geotechnical engineering, in particular to a steel plate pile utilizing bolt connection and an H-shaped combined foundation pit support structure. The H-shaped combined foundation pit support structure comprises the steel plate piles for water stopping for a foundation pit and H-shaped steel for earth blocking for the foundation pit. Two adjacent steel plate piles are connected through U-shaped fasteners. The steel plate piles are connected with the H-shaped steel through fixing bolts. The H-shaped combined foundation pit support structure is good in integrity, high in rigidity, fast to construct, recycling, environment-friendly, and easy to demount after construction, advantages of the steel plate piles and the H-shaped steel are brought into full play, and earth block and water stopping can be performed simultaneously.
Description
[0001] technical field [0002] The invention relates to the technical field of geotechnical engineering, in particular to the technical field of a foundation pit support structure combined with steel sheet piles and H-shaped steel. [0003] Background technique [0004] The steel sheet pile is a kind of hot-rolled (or cold-formed) section steel with locks or jaws. After being driven in, the locks or jaws are connected and occluded to form a continuous steel sheet pile enclosure wall for retaining soil and water. . It has the characteristics of fast and simple construction, recycling, and good economy, and has been widely used in water conservancy, transportation and other industries. However, due to the relatively small lateral stiffness of the steel sheet pile, the deformation is relatively large. It is seldom used in foundation pit projects with high requirements on the surrounding environment and large excavation depths. [0005] H-shaped steel is an economical cross...
