Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit support, in particular to a combined assembled inclined steel support device for foundation pit support of a construction project. Background Art

[0002] With the continuous development of cities, and against the background of increasingly tight urban land resources, more and more foundation pits are moving towards densely built urban centers, resulting in an increasingly complex environment surrounding the foundation pits and deeper excavation depths.

[0003] At present, the horizontal support system of deep foundation pit engineering mainly includes cable rod system and internal support system, but the anchor rod system is generally anchored outside the foundation pit, affecting the normal use of other plots or adjacent buildings. Therefore, the subsequent development of the cable rod system in the field of foundation pit support will inevitably be restricted by the objective environment; and the construction cost of the internal support system is high and the construction period is long. At the same time, the setting of the internal support system also leads to earth excavation and working space first, which increases the difficulty of earth excavation. The existing oblique throwing support system can well solve the problem of the cable rod system affecting the surrounding plots or buildings, and compared with the internal support system, it has the characteristics of low cost and short construction period.

[0004] However, the oblique cast support system in the prior art is limited by the layout form and often requires the arrangement of protruding concrete supports in the foundation pit to realize the setting of the oblique cast steel support device so as to support the foundation pit. The cast concrete supports cannot be adjusted in angle after the casting is completed, and the concrete supports need to be disassembled and assembled after the support device is removed, which increases the layout cost and makes the support process more complicated, bringing great inconvenience to the support of the foundation pit. In view of this, we propose a combined assembled oblique cast steel support device for construction engineering foundation pit support. Utility Model Content

After the support device is dismantled, the concrete supports need to be disassembled and assembled, which increases the layout cost and makes the support process more complicated, bringing great inconvenience to the support of the foundation pit.
