Cement Mill Foundation Hanging Reserved Hole Embedding Method

Abstract

The invention discloses a cement grinding mill foundation suspension type reserved hole embedding method. The problems that existing reserved hole embedding construction is high in cost, large in difficulty, prone to excursion and the like are solved. The embedding method includes the following steps: (1) preparing reserved hole model sets, wherein a foundation at the feeding end of a cement grinding mill and a foundation at the discharging end of the cement grinding mill are each provided with N reserved holes, and the reserved holes are divided into 2 / N reserved model sets, and N is an even number; (2) installing suspension type reserved hole supports outside the foundations; (3) arranging longitudinal central steel wires and transverse central steel wires of reserved hole models at the upper portions of the structural steel supports of the feeding end grinding foundation and the discharging end grinding foundation; (4) setting up a level gage measurement platform used for measuring the elevations of the reserved hole models of the feeding end grinding foundation and the discharging end grinding foundation at the positions of pegs through scaffold steel tubes, and gradually measuring the elevations of the reserved hole model sets when the reserved hole model sets are installed; (5) installing the reserved hole model sets, wherein the reserved hole model sets are installed on the suspension type reserved hole supports; (6) the reserved hole model sets are hoisted and fixed.

Description

technical field [0001] The invention relates to a method for embedding a reserved hole, in particular to a method for embedding a cement mill foundation suspended type reserved hole. Background technique [0002] In the construction of the cement mill foundation, a large number of reserved holes need to be buried. The reserved holes are used to fix the base of the ball mill and are required to be formed with concrete at one time. In order to ensure the installation accuracy of the ball mill, the accuracy requirements for the center distance of the inlet (outlet) material end, the center line of the mill, and the formation of the reserved holes are very high, and must be guaranteed to meet the design requirements. However, in the actual civil construction process, due to the stability of the reserved holes and the pouring of concrete, etc., it is very easy to cause the reserved holes to shift and be forced to repair, which affects the construction quality and construction per...

Problems solved by technology

However, in the actual civil construction process, due to the stability of the reserved holes and the pouring of concrete, etc., it is very easy to cause the reserved holes to shift and be forced to repair, which affects the construction quality and construction period, and increases the construction cost; even After it was put into production, it was found that the sliding shoe bearing of the ball mill was eccentrically worn, which seriously affected normal production
