Precise control construction method for 3D fabrication and installation of embedded part in large deep foundation pit column

Abstract

The invention discloses a precise control construction method for 3D fabrication and installation of an embedded part in a large deep foundation pit column, and relates to the technical field of 3D installation and precise control of embedded parts. The precise control construction method comprises the steps of firstly checking an outer scaffold for safety during installation of the embedded partat the position of a shaft, and ensuring that no potential safety hazards exist; all standby embedded parts must be placed at safety positions in the installation process of embedded part installationpersonnel, and are prevented from falling down from the scaffold to injure persons; workpieces can not be thrown during transfer, and all operators need to wear safety helmets and fasten safety belts; smoking is strictly prohibited on site; during operation of electric welders, wires need to be connected with a leakage protector; during electric welding operation, specially-assigned persons needto be arranged for fire control, and two dry powder fire extinguishers and a pail of water need to be placed at the construction position; and persons working aloft need to take physical examination firstly, and those with hypertension, heart diseases and the like can not work aloft. The precise control construction method for 3D fabrication and installation of the embedded part in the large deepfoundation pit column has the advantage of precise construction, and the deviation problem of the embedded part is solved.

Description

technical field [0001] The invention relates to the technical field of precise control of 3D installation of embedded parts, in particular to a precise control method for 3D production and installation of embedded parts in large deep foundation pit columns. Background technique [0002] The embedded parts are the components pre-installed in the concealed project, which are the structural parts placed during the pouring of the structure. They are used for lap joints when the superstructure is built to facilitate the installation and fixing of the external engineering equipment foundation. Most of the embedded parts are made of metal Manufacture is to leave members made of steel plates and anchor bars in the structure, which are used to connect structural members or non-structural members for fixed purposes, such as connectors for post-process fixation. There are many parts where concrete structures and steel structures are connected , For example: steel bar or cast iron, non-...
