In the installation and construction of the gas turbine unit, the anchor bolts have the function of ensuring the levelness and positioning of the unit, and are particularly used as a reference for the levelness adjustment of a stator. Therefore, the operation of the unit is directly influenced by the construction quality of the foundation bolts. Particularly, in a large-scale gas turbine unit, the installation accuracy of the foundation bolts has greater influence on the stability of the unit operation.
The embedded part is a member pre-installed in concrete and mainly used as a connecting part or a building part of the foundation bolt in the subsequent construction process. In a construction site, because the stability of the steel bars and the temporary supports is poor, impact force generated in the concrete pouring process can impact the embedded part, so that the fixed position of the embedded part is changed violently. In addition, under the condition, the position of the embedded part is changed randomly and uncontrollably due to concrete impact, so that the mounting precision of the embedded part can not meet the design requirement frequently, the gas turbine can not be normally mounted and fixed, and the whole construction progress is influenced.
Meanwhile, the foundation bolts are strictly required to be installed, the conventional foundation bolts are often installed and placed by being assisted by a mold, a bracket or other fixtures, the deviation conditions of X, Y shafts of the mold and the heights of the foundation bolts are repeatedly checked through a theodolite and a level gauge which are placed at proper positions so as to ensure that the positions and the heights of the foundation bolts are within an allowable tolerance range (for example, the allowable deviation of the verticality of the bolts is not more than L/200 and not more than 5mm, the inclination is not more than 1.0/1000 and the like), then, the concrete can be poured for one time, and after the concrete is cured (generally, the periphery or more is needed), the shaping mold can be disassembled. Meanwhile, in order to enable the foundation to uniformly support the weight of the equipment, secondary grouting is often needed for a gap between a chassis of the combustion engine and a concrete foundation. The construction process is relatively complicated and the construction period is long.

The structure can correct position degree deviation and perpendicularity deviation of the foundation bolt embedded part, and design requirements cannot be met when the foundation bolt embedded part is installed on site, so that interference or reworking with equipment is avoided, and installation progress is influenced.
The method aims to solve the problems that the embedded part cannot be accurately adjusted and the installation precision is low in the process of fixing the embedded part of the steam turbine by adopting a conventional method; patent document CN106869162B discloses a steam turbine embedded part fixing device and method.
