High-voltage distribution line iron tower foundation pit construction method

LIU KANGSHENG

The invention provides a high-voltage distribution line iron tower foundation pit construction method, and relates to the technical field of iron tower foundation pit construction. A base and a positioning device are provided, and the positioning device is fixedly installed on the base. The high-voltage distribution line iron tower foundation pit construction method can solve the following problems that a, in the construction process of an existing iron tower foundation pit, foundation pit construction formworks are prone to shaking when placed, the foundation pit construction formworks cannot be in a vertical state, and therefore deformation is prone to occurring after a pile foundation for pouring cement paste is formed; and b, when the existing iron tower foundation pit is constructed, firstly, a plurality of foundation pit construction modules need to be placed into the foundation pit, then the cement paste is injected into the foundation pit construction modules, after the interiors of the foundation pit construction modules are subjected to the pressure of the cement paste, the stability between the foundation pit construction formworks becomes poor, the foundation pit construction formworks can deviate, and therefore large gaps occur at the joints between the foundation pit construction modules.

本发明提出一种高压配电线路铁塔基坑施工方法，涉及铁塔基坑施工技术领域，包括底座和定位装置，底座上固定安装有定位装置,本发明能够解决以下问题：a.现有的铁塔基坑在施工的过程中基坑施工模板在放置的时候容易晃动，且基坑施工模板无法处于竖直状态，从而容易导致浇筑水泥浆的桩基成型后出现变形。b.现有的铁塔基坑在施工时，首先要将多块基坑施工模块放到基坑中，随后对基坑施工模块的内部进行水泥浆的注入，基坑施工模块板的内部在受到水泥浆的压力后，基坑模板之间的稳定性变差，基坑施工模块板会出现偏移，从而导致基坑施工模块之间的接缝处出现较大的缝隙。
