Embodiment Construction
[0044] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:
[0045] The present invention provides a sleeve grouting material mixed with iron filings and fine sand, and a preparation method and a supporting strength detection method. This application uses processed iron filings and fine sand to replace the aggregate in the original sleeve grouting material, which can greatly improve the sleeve after use. The strength of the barrel grouting material is low in cost because the application mainly uses pig iron filings to prepare it, and the prepared barrel grouting material can ensure product reliability through real-time rapid analysis and detection of compressive strength.
[0046] As a specific example of the sleeve grouting material mixed with iron filings and fine sand in the present invention, the sleeve grouting material of the present invention is calculated in parts by weight, including the following compon...
