Dear experts, the tank body that has just been welded shows severe unevenness in its bottom plate; when a person enters the tank, the bottom plate appears to rise and fall like the deck of a ship. According to GB50128, the maximum degree of unevenness allowed is 5 centimeters. The questions are as follows: First, how can this degree of unevenness be measured? This involves negotiations with the construction party – is there any third party that can carry out such measurements? Second, if the degree of unevenness exceeds the specified requirements, how should it be corrected? Thank you
1. Are the design documents complete? 2. Are the construction documents complete? 3. How is the foundation inspected?
Is the welding structure at the bottom of the storage tank lap-type? If it’s a lap joint, unevenness is inevitable
How to measure it? Is there a solution?
