Molding construction method of large-scale equipment foundation deep reserved foundation bolt hole

Abstract

The invention discloses a molding construction method of a large-scale equipment foundation deep reserved foundation bolt hole. The method comprises the working procedures of manufacturing an inner mandrel, winding and wrapping a protective layer of the inner mandrel, mounting and fixing the inner mandrel, pouring concrete, and the like. Through repetitious practices, a hole forming method that inner and outer layered and disassembled mandrels are self-made by square timbers, colored cloth strips and coir ropes is adopted, thereby realizing that an upper aperture and a lower aperture are same so as to form the deep reserved foundation bolt hole required by the design, and the hole forming depth can reach 2 m. In addition, the square timbers, the colored cloth strips and the coir ropes used in the method are easy to obtain from local sources and can be recycled for multiple times so as to be beneficial to saving the cost.

Description

technical field [0001] The invention relates to a construction method for forming deep reserved anchor bolt holes for large-scale equipment foundations. Background technique [0002] With the development of modern industrial technology, the volume of commonly used industrial equipment is getting smaller and smaller, and the basis for configuration is also getting smaller and smaller. However, there are still some large-scale equipment that are restricted by installation and maintenance process conditions. The volumetric reinforced concrete foundation even needs to fix the anchor bolts after the equipment is installed or remove the anchor bolts first when the equipment is overhauled in the later stage. For the former, the deep-type reserved anchor screw holes are mostly used, and the latter mostly use the super-long anchor bolts of the tool-type anchor plate at the lower end. After the equipment is installed, the holes are filled with sand, and the upper mouth is poured with ...

Problems solved by technology

[0003] The purpose of this invention is to solve the problem that the deep-type reserved anchor screw hole core is not easy to remove, the hole is easy to break and the upper opening is too large to facilitate the placement of leveling iron during equipment installation, and to provide a reliable technical guarantee for equipment installation. It is easy to obtain local materials, the main materials can be recycled and reused, easy to operate, convenient to construct, and save a lot of manual secondary repairs in the later period.
