Problems solved by technology
[0002] When excavating a deep foundation pit, it is necessary to make a retaining wall on the wall of the foundation pit. The main purpose is to support, retain soil or water. Due to its strong retaining force, it is necessary to provide a relatively strong and reliable retaining pile for the retaining wall. Traditional The retaining wall pile is an upright concrete column, which can bear limited lateral force. In some soft soil conditions, it is easy to deform, which will cause the retaining wall to shift, which will have a great impact on the excavation of the foundation pit.

Embodiment Construction
[0009] The present invention is a retaining pillar assembly, there is a protective assembly around the retaining pillar, the protective assembly has two layers, the inner layer 1 is a reinforcement mesh close to the retaining pillar, and the outer layer 2 is connected with the inner layer 1 by a short steel bar 4 A steel pipe, pouring concrete 3 between the outer layer 2 and the inner layer 1. The outer layer 2 can be replaced by an aluminum alloy tube.
[0010] The invention adopts the protective net to pour concrete, increases the area of its cross section, and increases the transverse steel bars at the same time, so its transverse bearing capacity is greatly improved. The invention has the characteristics of simple structure, practicality and convenience.

The invention relates to a retaining wall column component. A protection component surrounds a retaining wall column. The protection component comprises two layers, the inner layer is a reinforcing mesh tightly attached to the retaining wall column, the outer layer is formed from steel tubes connected with the inner layer using short reinforcing steel bars, and concrete is cast between the outer layer and the inner layer. The outer layer can be replaced by aluminum alloy tubes. A protective mesh is adopted during concrete casting, the section area is increased, and the transverse reinforcing steel bars are increased. Therefore, the transverse bearing capability is greatly increased. The retaining wall column component has the characteristics of simple structure, practicability and convenience.
Description
technical field [0001] The present invention relates to a retaining post assembly. Background technique [0002] When excavating a deep foundation pit, it is necessary to make a retaining wall on the wall of the foundation pit. The main purpose is to support, retain soil or water. Due to its strong retaining force, it is necessary to provide a relatively strong and reliable retaining pile for the retaining wall. Traditional The retaining wall pile is an upright concrete column, which can bear limited lateral force. In some soft soil conditions, it is easy to deform, which will cause the retaining wall to shift, which will have a great impact on the excavation of the foundation pit. Contents of the invention [0003] In order to overcome the above-mentioned shortcoming of the prior art, the object of the present invention is to provide a kind of retaining pillar assembly, which adopts protective net to pour concrete, increases its cross-sectional area, and increases transve...
