A circular integral support structure for a large, deep excavation

摘要

A circular integral support structure for a deep, large construction pit, characterized in that: which comprises a first support profile (1) and more than one second support profile (2) and a reinforcing column member (3), with every second support profile (2) passing through each reinforcing column member (3) is firmly connected to the bottom of the first support profile (1); wherein the first support profile (1) comprises an annular crown beam (101), a first annular support (102) and a first reinforcing reinforcement support (105), the annular crown beam (101) and the first annular support (102) distributed in concentric circles and the first annular support (102) is fixedly connected to the inner periphery of the annular crown beam (101) through the first reinforcing reinforcement column (105) in the peripheral annular distribution; wherein the second support profile (2) comprises an annular waist beam (201), a second annular support (202) and a second reinforcing reinforcement support (204), the annular waist beam (201) and the second annular support (202) distributed in concentric circles and the second annular support (202) is fixedly connected to the inner periphery of the annular waist bar (201) through the second reinforcing reinforcement support (204) in the peripheral annular distribution; wherein the reinforcing column member (3) comprises a column body (301), a damped hydraulic cylinder assembly (303) and a vibration damping base assembly (304), the vibration damping base assembly (304) being movably connected to the lower end of the column body (301), wherein the damped hydraulic cylinder assembly (303) has two widths, which are symmetrical on both sides of the lower end of the column body (301) and wherein the column body (301) is fixed to the ground within the deep large pit by the damped hydraulic cylinder assembly (303) and the anti-vibration base assembly (304).
