Reinforced protection structure for side wall of foundation pit

Abstract

The invention discloses a reinforced protection structure for the side wall of a foundation pit. A side wall protection net is fixedly connected between adjacent protection columns, the protection columns are attached to the side wall of the foundation pit, and reinforcing steel bars inserted into the side wall of the foundation pit are fixedly installed on the rear surfaces of the protection columns. According to the structure, the protection columns which can stretch out, draw back and achieve limiting and fixing are used for serving protection piles of the side wall of the foundation pit, the rear walls of the protection columns are inserted into the side wall of the foundation pit through the reinforcing steel bars to be fixed, the side wall protection net is connected between the protection columns evenly distributed on the side wall of the foundation pit and used for shielding a soil layer of the side wall to prevent the soil layer from collapsing, the protection net and the protection columns as well as the protection columns and the side wall of the foundation pit are convenient to disassemble, repeated utilization can be achieved, and resources are saved; and meanwhile, compared with traditional protection pile pouring and reinforcing mesh laying construction, the structure is short in time, the phenomenon that concrete protection arms on the outer surface of a reinforcing mesh fall off after long-term use can be avoided, and harm to users is avoided.

Description

technical field [0001] The invention belongs to the technical field of reinforced protective structures, and in particular relates to a reinforced protective structure used for the side walls of foundation pits. Background technique [0002] In the prior art, in the process of excavating the foundation pit, firstly, the protective piles will be drilled and poured at the selected location, and the foundation pit will be dug along the protective piles. The soil between the piles is protected by shotcrete. Lay steel mesh, and then spray concrete retaining wall on the outside, the thickness of retaining wall is about 100mm. [0003] In this construction method, the side wall of the foundation pit is protected by the reinforcement mesh, and at the same time, the sprayed concrete retaining wall has a waterproof effect. For a long time, it is difficult to dismantle the protective structure, and the materials cannot be reused many times, resulting in a waste of resources. At the sa...

[0003] In this construction method, the side wall of the foundation pit is protected by the reinforcement mesh, and at the same time, the sprayed concrete retaining wall has a waterproof effect. For a long time, it is difficult to dismantle the protective structure, and the materials cannot be reused many times, resulting in a waste of resources. At the same time, when the use time is long, the concrete arm guards on the outside of the steel mesh will fall off, which is easy to damage the construction in the foundation pit. person causing injury
