Embodiment Construction
[0020] The invention adopts the positioning tool to cooperate with the hoisting equipment to install the medium-heavy horizontal equipment of the nuclear power plant.
[0021] Before installing the heavy horizontal equipment in the nuclear power plant, first mark the position of the longitudinal axis and the transverse axis of the base on the base of the heavy horizontal equipment, and mark on the foundation pier used to install the heavy horizontal equipment The positions of the longitudinal axis and the transverse axis of the foundation pier are shown.
[0022] Such as figure 1 As shown, place the pad iron 1 on the foundation pier 2, and level the pad iron 1, and place the two as figure 2 The positioning tool 3 shown is placed and fixed on the foundation pier 2, the two positioning tools 3 are respectively located on both sides of the shim 1 and the elevation of the connecting plate 31 on the positioning tool 3 is lower than that of the shim 1. The two ends of the bottom ...

The invention relates to the field of nuclear power station building. In order to solve the problems of inaccurate installation position, low installation speed, long time consumption, labor waste and material waste during the installation of heavy horizontal equipment in the nuclear power station in the prior art, the invention provides a method for installing the heavy horizontal equipment in the nuclear power station. Pad iron is arranged on a base pier and is leveled, two positioning toolings are arranged at two sides of the pad iron and are fixed on the base pier, and hoisting equipment is used for hoisting the heavy horizontal equipment onto the base pier and placing the heavy horizontal equipment to a position between two baffle plates of the positioning toolings, so the vertical axial line of the base of the heavy horizontal equipment is aligned with the vertical axial line of the base pier, the heavy horizontal equipment is regulated so that the transverse axial line of the base of the heavy horizontal equipment is aligned with the transverse axial line of the base pier, then, the base is placed onto the pad iron and is fixed on the base pier through foundation bolts, the positioning toolings are taken out, in addition, the foundation bolt grouting and the equipment base grouting are carried out, and the installation is completed. The installation method has the advantages that the method is simple, the operation is easy, the installation precision is high, the time and the labor are saved, and the installation efficiency is high.
Description
technical field [0001] The invention relates to the construction field of nuclear power plants, in particular to a method for installing heavy horizontal equipment in nuclear power plants and a positioning tool used during installation. Background technique [0002] In the prior art, when installing heavy-duty horizontal equipment in a nuclear power plant such as the main oil storage tank of a diesel engine, at first, the pad iron is placed on the foundation pier used to install the main oil storage tank of the diesel engine, and the main oil storage tank of the diesel engine is lifted by lifting equipment. The oil tank is hoisted, moved over the foundation pier and placed on the shim. Next, manually adjust the position of the main oil storage tank of the diesel engine with a jack, so that the longitudinal axis and the transverse axis on the base of the main oil storage tank of the diesel engine are respectively aligned with the longitudinal axis and the transverse axis of t...
