Problems solved by technology
[0002] The engineering oil storage tank (intermediate tank group) is located at the engineering site of the catalytic dewaxing / lubricating oil production unit. After the hydraulic test, the bottom of the tank (especially the middle position of the tank bottom) is prone to different degrees of settlement, and there are serious problems. Security risks
If the tank is dismantled and rebuilt, the construction cost is high and the construction period is long, and the reconstruction of a single building may cause long-term shutdown of the entire line, resulting in huge economic losses

The invention relates to an oil storage tank foundation grouting reinforcement treatment method, wherein the tank bottom edge of an oil storage tank is fixed on a ring wall. The oil storage tank foundation grouting reinforcement treatment method includes the following steps that firstly, hole sites are arranged outside the ring wall of the oil storage tank, and a grouting pipe is shot into the soil mass below the tank bottom of the oil storage tank; and secondly, grouting equipment is connected to the initial end of the grouting pipe in the shooting direction for grouting, soil mass voids arefilled, the shooting direction of the grouting pipe faces a center shaft of the oil storage tank, and the pipe wall of the part, shot into the soil mass below the tank bottom, of the grouting pipe isprovided with grout vent holes. According to the scheme, through grouting reinforcement treatment, the springing height of a tank bottom plate basically meets design requirements under the grouting and filling action of backfills in a tank foundation, and meanwhile the safety use requirements are satisfied.
Description
technical field [0001] The invention belongs to the technical field of construction engineering maintenance, and in particular relates to a grouting reinforcement treatment method for an oil storage tank foundation. Background technique [0002] The engineering oil storage tank (intermediate tank group) is located at the engineering site of the catalytic dewaxing / lubricating oil production unit. After the hydraulic test, the bottom of the tank (especially the middle position of the tank bottom) is prone to different degrees of settlement, and there are serious problems. Security risks. If the tank is dismantled and rebuilt, the construction cost will be higher and the construction period will be longer, and the reconstruction of a single building may cause long-term shutdown of the entire line, resulting in huge economic losses. [0003] Therefore, there is a need for an oil storage tank base reinforcement method that does not affect normal production operations and is easy...
