Further, the quantity of described curved plate is two, and the quantity of described steel supporting plate is two
Individual, the position of two described curved plates is corresponding with the position of two described steel supporting plates respectively.
Further, described bracing members is provided with at least one U-shaped anchor ear, described U-shaped armful
The kink of hoop and the upper surface abutting contact of bracing members, described bracing members is solid by U-shaped anchor ear
It is scheduled on plane steel plate.
Further, the two ends of described U-shaped anchor ear are screwed connection post, two connections
Post is each passed through circular hole corresponding on plane steel plate the nut matched that is spirally connected.
Further, described fixing post is square lattice column, and the lower end of lattice column is fixed on base
In the stake at the end, hole, hole.
The present invention has the advantage that as follows: bracing members is shelved on curved plate by the present invention, arc
Shape steel plate, plane steel plate, steel supporting plate constitute steel bracket on fixing post, formed one stable
Entirety, bracing members is fixed by U-shaped anchor ear, can effectively limit the position of bracing members
Move, thus increase the stability of bracing members.It solve single long bracing members planar outer
Stability problem, adds the safety of base pit engineering, saves construction investment.The present invention has
There are the advantages such as design and easy construction, economical rationality, increase foundation ditch general safety, it is adaptable to steel
Support the deep-foundation pit engineering as inner support system, subway foundation pit engineering has good answering
Use prospect.

Detailed description of the invention
Describe the performance of the present invention below in conjunction with the accompanying drawings in detail, but it is not intended that this
Bright restriction, only illustrates.Simultaneously by explanation, advantages of the present invention will become more
Clear and easy to understand.
As shown in Figure 1 and Figure 2, a kind of increase the device of single bracing members stability in foundation ditch,
Including horizontally disposed bracing members 5 and fixing post vertically disposed with bracing members 5, fixing post is
Square lattice column 6, lattice column 6 lower end is fixed in the stake at the bottom of Foundation Pit.On fixing post admittedly
Surely steel bracket, steel bracket is had to include plane steel plate 4, steel supporting plate 1 and curved plate 2, plane
Steel plate 4 is welded on lattice column 6, the back side of plane steel plate 4 be disposed with two be parallel to each other between
Every the steel supporting plate 1 arranged, steel supporting plate 1 is the most trapezoidal, and two right-angle sides of steel supporting plate 1 are respectively
Weld with lattice column 6 and plane steel plate 4 phase.It is disposed with two on plane steel plate 4 to be parallel to each other
Spaced curved plate 2, curved plate 2 is welded on plane steel plate 4, curved plate
2 for the spacing of bracing members 5 and support.Two intervals that are parallel to each other it are provided with on bracing members 5
The U-shaped anchor ear 3 arranged, bracing members 5 is fixed on plane steel plate 4 by U-shaped anchor ear 3.
The position of two curved plates 2 is corresponding with the position of two steel supporting plates 1 respectively, adds further
The stability of strong supporting construction.In actual applications, bracing members 5 can the most multiple rows of be parallel to each other
