Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit support, in particular to a circumferentially convertible support component suitable for various types of ramps. Background Art

[0002] With the rapid development of underground space, the basements of buildings are getting deeper and deeper, and the foundation pit supports are increasing. Internal supports are widely used in foundation pit support design schemes because of their simple construction and are not restricted by the construction of surrounding sites.

[0003] Due to the conflict between the support system in the foundation pit and the basement structure, the existing construction sequence is generally to backfill the fertilizer trough after the construction of the first layer of structure, and set a force transmission belt between the foundation pit retaining structure and the outer wall of the basement to transfer the soil pressure of the foundation pit side wall to the main structure, and then remove the support in the foundation pit layer to carry out the construction of the next layer of the main structure. The underground ramp generally lags behind the main structure of the main structure, so the outer wall of the ramp is a cantilever retaining wall when the inner support is removed. In order to prevent the soil pressure of the foundation pit side wall from endangering the structural safety of the outer wall of the ramp, it is necessary to take support replacement measures between the inner wall of the ramp side wall and the outer wall of the basement.

[0004] The existing support replacement technology is to set steel pipe or concrete support between the outer wall of the basement and the inner wall of the ramp side wall. The use of concrete support is suitable for the replacement support construction of special-shaped wall ramps with less than ideal construction conditions, but it has a long construction period and high cost, and the concrete support needs to be cut after the support replacement and cannot be reused. However, since the size of the steel pipe support is fixed, it is only suitable for straight ramps with good construction conditions. At the same time, in order to increase the load-bearing surface and reduce concentrated loads, the steel pipe support is generally provided with concrete side beams or connected to the main structure by welding steel plates, which also results in material waste. To this end, the utility model proposes a circumferentially convertible support component suitable for various types of ramps to solve the above problems. Utility Model Content
