Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit reinforcement installation, in particular to a precise positioning device for foundation pit reinforcement. Background Art

[0002] The main role of the steel cage is the same as the stress on the longitudinal steel bars of the column. It mainly plays a tensile role. The compressive strength of concrete is high but the tensile strength is very low. It restrains the concrete of the pile body so that it can withstand a certain axial tension. During the construction of bridges, culverts or high-rise buildings, the foundation may be required to be piled according to requirements. The method is to use machine punching and water drilling, and the hole depth meets the design requirements. Then lower the steel cage into the pile hole, and then insert the conduit for concrete pouring. If this component is independent, we pre-make the steel bars around this component. This is the steel cage. Usually we call pre-made steel structures such as bored piles, bored piles, and columns steel cages.

[0003] When the steel cage is placed in the prefabricated foundation pit for pouring, it is necessary to position the steel cage in the prefabricated foundation pit to prevent the steel cage from tilting. However, the existing positioning method is to adjust the steel cage at the mouth of the foundation pit and then place the steel cage. This is too simple and the accuracy of positioning the steel cage is not accurate enough. In addition, during the pouring of concrete, the steel cage may float up, which makes the positioning accuracy even more inaccurate, and is likely to lead to a decline in the quality of the subsequent project.
