The allowable deviation of the depth of the foundation pit should be ten 100mm, -50mm. When the deviation between the foundation pit depth and the design pit depth is more than 100mm due to soil quality reasons, it should be handled according to the following regulations: (1) When the deviation is +100mm and -50mm, stone paving and grouting should be used. (2) When the deviation exceeds +300mm of the specified value, the part exceeding +300mm can be tamped with soil or sand or stone. Then use paving stone grouting treatment. 5. The length of the anchor bolts buried in the concrete should be greater than 20 times its diameter, and should be welded firmly with the main reinforcement.
