【Embodiment】
Technological means, creation characteristic, reached purpose and effect to realize the utility model are easy to understand, below
With reference to embodiment, the utility model is expanded on further.
As Figure 1-3, open cut section foundation pit supporting system in the middle part of a kind of two built subway tunnels, including protective plate 1,
Pillar 2 and iron stake a10, the both sides of the protective plate 1 are mounted on pillar 2, and the outer wall of the pillar 2 is arranged with sleeve pipe 8, described
The outer wall of sleeve pipe 8 is provided with fixed seat a11, and the fixed seat a11 is connected by rotary shaft a18 with expansion link 12, described flexible
Bar 12 is plugged in the top of fix bar 13, and the outer wall of the fix bar 13 is plugged with bearing pin 14, and one end of the fix bar 13 leads to
Cross rotary shaft b15 to be connected with fixed seat b19, the bottom of the fixed seat 19 is provided with fixed block 16, the bottom of the fixed block 16
Portion is provided with iron stake b17, and the bottom of described sleeve pipe 8 is connected with limited block 9, and the bottom of the limited block 9 is provided with iron stake a10.
Wherein, the outer wall of the protective plate 1 is provided with steel bar 4, and the number of steel bar 4 is 2, and the steel bar 4, which intersects, to be connected
