Embodiment Construction

[0020] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0021] Such as figure 1 As shown, a method for secondary grouting in the process of equipment foundation construction, the specific steps are:

[0022] a. Conduct a comprehensive check on the construction drawings before construction to ensure that there are no errors in the construction drawings;

[0023] b. When constructing the equipment foundation 3 according to the requirements of the construction drawings, install the outer formwork of the equipment foundation 3 to the top elevation of the secondary grouting;

[0024] c. PVC corner line 2 is installed on the top plate of the outer formwork;

[0025] d. According to the grouting height required by the construction drawings, a groove is left on the inner side of the equipment foundation 3 as the equipment foundation grouting groove 1. The depth of the equipment foundation grouting groove 1 is 30-50mm lo...

Abstract

The invention discloses a method for secondary grouting in an equipment foundation construction process. The method specifically includes the steps that an external formwork of an equipment foundationis installed at the top elevation of secondary grouting; PVC angular lines are installed on a top plate of the external formwork; a groove is formed in the inner side of the equipment foundation to serve as an equipment foundation grouting groove according to the grouting height required by a construction drawing; large-volume concrete water-storage curing is performed through the equipment foundation grouting groove; formwork removal and rough chiseling are performed after the curing period; equipment installation, correction and acceptance check are performed; and after equipment installation passes acceptance check, the equipment foundation grouting groove is cleaned, and secondary grouting is performed to fill and level up to the designed elevation. By means of the method for secondary grouting in the equipment foundation construction process, a secondary grouting formwork installation procedure is omitted, and the appearance technique is improved; and the working efficiency is improved, the number of procedures is reduced during foundation construction, secondary grouting is directly performed in the equipment foundation grouting groove, a formwork erecting procedure of the secondary grouting is omitted, cleaning can be completely performed after equipment is put in place so that secondary grouting operation can be performed, and then time is saved for equipment installation.

Description

technical field [0001] The invention relates to the technical field of secondary grouting construction of equipment foundations in electric power construction, in particular to a method for secondary grouting in the construction process of equipment foundations. Background technique [0002] In the construction of electric power construction projects, most of the equipment foundations need secondary grouting. The conventional method is: first construct the equipment foundations to the bottom level of the grouting layer, and after the equipment is installed and aligned, then clean and support the formwork, and then carry out secondary grouting. grouting. This method has complicated procedures, because the materials of the base concrete and the secondary grouting material are different, the color of the concrete base layer and the grouting layer are inconsistent after the construction is completed, and there are traces of construction joints that are difficult to deal with, th...
