Hanging channel device for foundation pit

Abstract

The invention discloses a hanging channel device for a foundation pit. The channel device comprises a concrete foundation platform arranged at the top of the foundation pit, a supporting frame fixed to the platform and a fast-mounted hanging ladder cage fixed to the supporting frame and going deeply into the foundation pit downwards. The fast-mounted hanging ladder cage comprises ladder cage standard sections and Z-shaped staircases, wherein the ladder cage standard sections and the Z-shaped staircases are spliced downwards layer by layer. Each ladder cage standard section comprises at least three ladder cage vertical rods and transverse braces fixed to the corresponding ladder cage vertical rods and defining a closed frame with the corresponding ladder cage vertical rods. The ladder cagevertical rods at the tops of the ladder cage standard sections are fixed to the supporting frame. The reset adjacent corresponding ladder cage vertical rods in the ladder cage standard sections are connected through connecting parts. Each Z-shaped staircase includes a resting platform arranged corresponding to each ladder cage standard section and a step fixed to the vertical adjacent resting platforms. Each resting platform is provided with a clamping groove and is arranged at the corresponding transverse brace of the corresponding ladder cage standard section to be fixed in a clamped mode. The hanging channel device is suitable for going up and down of workers under the condition of constant changing of the excavation depth in the excavation process, the site adaptability is high, assembly and disassembly are convenient and flexible, the structure is safe and reliable, and the hanging channel device can be repeatedly used.

Description

technical field [0001] The invention relates to the fields of bridges and construction engineering, in particular to a suspension channel device for foundation pits and an installation method thereof. The suspension channel device for foundation pits is especially suitable for the situation that the excavation depth changes continuously during the excavation process of deep foundation pits. . Background technique [0002] In the construction of deep foundation pit engineering, on-site construction personnel need to enter the foundation pit through the upper and lower passages to carry out construction work. During the construction of conventional deep foundation pits, the upper and lower passages of the foundation pit are mostly welded by steel pipes, section steel and steel plates, and the upper and lower passages of corresponding heights need to be welded according to the depth of the foundation pit. The disassembly and assembly process of such upper and lower passages is ...
