Sheol is NOT THE GRAVE, as a cursory study shows;
there is too much evidence to put it all here so I'll post one url of so many that will provide what you clack:

Hades is the New Testament equivalent of the Old Testament word Sheol. The Greek and Hebrew words speak of the same place, the present Hell. However, this is problematic because Sheol has been translated "grave" as often as it has "hell" and some have mistakenly taught that Sheol and Hades are only references to the grave rather than Hell. This erroneous teaching leads to the denial of the existence of an immediate or present Hell. The false doctrine of soul-sleep, and other ideas that teach the unconscious state of the dead between death and resurrection, spring from this error.
The common word for "grave" in the Old Testament is
queber. Of the sixty-four times it is used, it is translated "grave" thirty-four times, "sepulcher" twenty-six times, and "burying place" four times. Queber is used five additional times as part of a place name, Kibroth-hattaavah, which means "graves of lust." As we said earlier, Sheol is found sixty-four times, being rendered "grave" thirty-one times, "hell" thirty-one times, and "pit" three times.
A comparison of how Sheol and queber are used reveals eight points of contrast that tell us that they are not the same thing.
1. Sheol is never used in plural form. Queber is used in the plural 29 times.
2. It is never said that the body goes to Sheol. Queber speaks of the body going there 37 times.
3. Sheol is never said to be located on the face of the earth. Queber is mentioned 32 times as being located on the earth.
4. An individual's Sheol is never mentioned. An individual's queber is mentioned 5 times.
5. Man is never said to put anyone into Sheol. Individuals are put into a queber by man (33 times).
6. Man is never said to have dug or fashioned a Sheol. Man is said to have dug, or fashioned, a queber (6 times).
7. Man is never said to have touched Sheol. Man touches, or can touch, a queber (5 times).
8. It is never said that man is able to possess a Sheol. Man is spoken of as being able to possess a queber (7 times). (These eight points of comparison are adapted from "Life and Death" by Caleb J. Baker, Bible Institute Colportage ***'n, 1941).
From the differences between how Sheol and queber are used in Scripture, it is obvious that they are not the same thing. The Greek word Hades in the New Testament would fit into the Sheol column of our chart, strongly indicating that it is the same thing as Sheol. Hades is used eleven times, being rendered Hell ten times and grave once.
ibid:
While we have not exhausted the subject by looking at every passage that Sheol is found in, it is clear from these examples that Sheol is not simply the grave but is located at the center of the earth and is the abode of the souls of the unrighteous dead who are awaiting their resurrection unto condemnation,
Psalm 9:17. It is equally clear that those in Sheol/Hades are not in an unconscious state of existence but are quite aware of what is going on around them. There is memory, recognition, and communication there.
PARADISE
While Paradise is not now a part of Sheol/Hades it will be mentioned here because it was located in Sheol/Hades at one time. Before the death, burial, and resurrection of Jesus Christ everybody who died went to Sheol/Hades, which was at that time divided into at least two compartments. One was a place of torment while the other was a place of blessing, which was referred to as Abraham's Bosom (Lk. 16:22-25).
Christ's soul was in Sheol/Hades between His death and resurrection. The place where Christ's soul went between His death and resurrection is also called paradise (Luke 23:43).
