The Larsen steel sheet piles are all tightly buckled with each other, and the formed foundation pit enclosure is square.
The clear distance between the UHPC beam and the top of the Larsen steel sheet pile is 80-100 cm.
The I-shaped steel is installed after the UHPC beam is poured and formed, and is erected on the UHPC beam, wherein the inner wall of the foundation pit enclosure is tightly attached to the I-shaped steel, and the edge of the foundation pit enclosure is welded.
And a plurality of I-steel supports are arranged on any corresponding side of the foundation pit enclosure, the clear distance of each I-steel is 100-120 cm, and the I-steel supports are all erected on the UHPC beam.
The high-strength bolts are distributed on two sides of the bolt plate, the edge distance between each row of high-strength bolts and the bolt plate is 3cm-5cm, and the clear distance between each row of high-strength bolts is 5cm-8 cm.
The utility model has the advantages that:
the utility model discloses mainly be a supporting construction who adopts UHPC and Larsen steel sheet pile combination, realized excavation supporting's stability and security to the efficiency of construction is high, the quality is secure, makes structural performance satisfy the construction requirement of industrialization, still has resource recycling, advantage such as environmental protection pollution-free simultaneously.
