Embodiment Construction

[0038] The following is attached Figure 1-8 The application is described in further detail.

[0039] refer to figure 1 , figure 2 , the embodiment of the present application discloses a temporary safety passage for a foundation pit. The safety passage is arranged in the foundation pit. The safety passage includes two sets of supporting frames 1 arranged parallel to each other. Specifically, the supporting frames 1 include first Vertical bar 11, the second vertical bar 12, the third vertical bar 13 and the fourth vertical bar 14, the height of the first vertical bar 11 is lower than the second vertical bar 12, the height of the second vertical bar 12 and the third vertical bar 13 Similarly, the height of the third vertical bar 13 is lower than that of the fourth vertical bar 14 .

[0040] refer to figure 2 , image 3 A first strut 15 is arranged between the first vertical bar 11 and the second vertical bar 12 , and the two ends of the first strut 15 are respectively conne...

Abstract

The invention relates to a temporary exit passageway for a foundation pit, and relates to the field of foundation pit construction equipment. The temporary exit passageway solves the problem that in the prior art, an exit passageway in a foundation pit is inconvenient to disassemble and move, and comprises two supporting frames arranged in parallel, the supporting frames comprise first supportingrods, second supporting rods and third supporting rods, each of the first supporting rods, the second supporting rods and the third supporting rods is provided with a plurality of sets of mounting holes, a plurality of step rods are erected between the corresponding first supporting rods and between the corresponding third supporting rods, mounting bolts arranged upwards are arranged in the mounting holes in a penetrating mode, and the mounting bolts sequentially penetrate through the mounting holes and the step rods and then are fixed through nuts; and an overlapping plate is erected betweenthe two second supporting rods, and the mounting bolts in the mounting holes in the second supporting rods sequentially penetrate through the mounting holes and the overlapping plate and then are fixed through nuts. The temporary exit passageway has the advantage of being convenient to disassemble and move.

Description

technical field [0001] The present application relates to the field of foundation pit construction equipment, in particular to a temporary safety passage for foundation pits. Background technique [0002] At present, the excavation of foundation pits is often involved in building construction. Foundation pits are earth pits excavated at the foundation design position according to the base elevation and foundation plane size. In the process of foundation pit construction, the staff need to go down to the foundation pit for construction. The way for the staff to enter the foundation pit is usually through a temporary scaffolding channel. This kind of scaffolding channel is generally obtained from local materials, and then the corresponding staircase is welded according to the demand, making it a temporary access to the foundation pit. However, due to the complex environment during the construction of the foundation pit, the temporary passage often needs to be moved, and the t...
