Method for forming no expansion joint in cast-in-place reinforced concrete rectangular structure and expansion deformation ditch structure

The invention relates to a method for arranging no expansion joint on a cast-in-place reinforced concrete rectangular structure and an expansion deformation ditch structure. An expansion deformation ditch is arranged at the position, where a deformation joint needs to be arranged, of the cast-in-place reinforced concrete rectangular structure; when the telescopic deformation groove is used for a wall plate of a rectangular structure, the set depth of the telescopic deformation groove is larger than the thickness of the outer side wall plate, and when the telescopic deformation groove is used for a bottom plate or a top plate, the depth of the telescopic deformation groove is larger than the thickness of the peripheral bottom plate or top plate. The rectangular structure is designed according to a conventional method; continuous construction and interval construction can be carried out at the telescopic deformation ditch, and construction and detection requirements are executed according to the current standar
