Aseismic strengthening structure with underground structure and strengthening method thereof
The invention discloses an aseismic strengthening structure with an underground structure. A seismic reduction layer and a seismic isolation wall are arranged, anchor rods are driven into a base plate and a side plate of the underground structure, and meanwhile a middle column which is most likely to be damaged in the anti-seismic process of the underground structure is subjected to reinforcement treatment. The underground structure is located in the surrounding soil mass, the anchor rods are arranged between the surrounding soil mass and the underground structure for strengthening, one end of each anchor rod stretches into the surrounding soil mass, and the other end of each anchor rod is fixed in the underground structure. The aseismic strengthening structure with the underground structure can be formed in the following steps that first, the seismic reduction layer is arranged, foamed resin is injected into the gaps in the periphery of the side plate and the base plate of the underground structure through drilling high pressure after drilling is conducted, and accordingly the seismic reduction layer is formed; second, the anchor rods are driven into the soil mass through the drilled holes filled with the foamed resin, and high-pressure grouting is conducted towards the insides of the anchor rods; third, the middle column of the underground structure is strengthened, steel angles are pasted at the four corners of the middle column, and the four steel angles are welded into a whole through steel plates; fourth, the seismic isolation wall of a certain depth is arranged at the position a certain distance away from the underground structure.
