Pile plate type retaining wall with pressure reducing plate

The invention relates to the technical field of buildings, in particular to a pile plate type retaining wall with a pressure reducing plate. The pile plate type retaining wall comprises a plurality of pile column assemblies, a plurality of plate walls, a top beam and the pressure reducing plate; The structure is not affected by geological conditions and foundation bearing capacity, can be suitable for the situation that the retaining wall is proposed to be built and is close to an existing building, and the stratum is mainly a soil layer with low bearing capacity, such as filled soil, and can further be used as an underground courtyard outer wall. A plurality of bottom piles are connected and fixed together through the top beam, and the stability of the bottom piles is improved. The pressure reducing plate can be arranged at the top beam or above the top beam according to the actual terrain, on the one hand, the pressure reduction plate can reduce horizontal deformation of the top of the plate wall, on the ot
