Construction process for leveling basic embedded part

Abstract

The invention provides a construction process for leveling a basic embedded part, comprising the following steps of popping an axial line of a basic embedded part on a basic layer, dividing a side line and a center line, drilling at an angular point of the popped axial line of the basic embedded part, embedding steel bars in the hole and correcting the verticality of the steel bars, setting a tie bar between the steel bars, welding nuts at the sides of the tops of the steel bars, screwing bolts which are used as adjusting supports on the nuts, marking a center line of a basic embedded part steel plate and placing on the bolts in contrast to the axial line, rotating the bolts to adjust the elevation of the basic embedded part steel plate, and fixing the nuts with the bolts after the leveling. According to the construction process, an independent-structure leveling method is used, so that the evenness of the basic embedded part is effectively ensured; and the adjusting supports are not in contact with a reinforcing facility of a template, so that the elevation error of the basic embedded part caused in the concreting process is effectively avoided.

Description

technical field [0001] The invention relates to a leveling construction technology, in particular to a leveling construction technology of foundation embedded parts. Background technique [0002] During the construction of the substation, the foundation of the main transformer is a cast-in-place reinforced concrete structure with pre-embedded galvanized steel plates. When pouring the main transformer foundation, the amount of concrete is very large, and the requirements for the flatness of the embedded parts are also high. At the same time, the buoyancy generated by pouring is also relatively large, all of which require precise leveling and positioning of the embedded parts of the main transformer foundation. However, the embedded part of the main transformer foundation is a heavy steel plate, and its axis position and flatness are difficult to control. The traditional method of leveling embedded parts is to directly weld the drawing wire to the surface of the embedded part...

However, the embedded part of the main transformer foundation is a heavy steel plate, and its axis position and flatness are difficult to control

The traditional method of leveling embedded parts is to directly weld the drawing wire to the surface of the embedded part, and fix the nuts on the reinforcement facilities of the formwork. However, this method has many defects, such as it is easy for the embedded parts to be partially heated during the electric welding process. If it is deformed, it is easy to damage the galvanized layer of the embedded parts, and the elevation of the embedded parts is likely to be misaligned with the vibration of the reinforced steel pipe.
