The invention relates to a construction method of a shallow foundation. The construction method comprises the following steps that earthwork is excavated to the elevation position of the bottom of a beam cushion layer; according to the position of the bearing platform in the drawing, excavation continues to be conducted on the earthwork till the bottom elevation of a bearing platform cushion layer is reached, and a first cushion layer is poured; bearing platform steel bars are bound on the first cushion layer, and steel bars are reserved at the haunched positions of the beams and frame beam columns; a bearing platform formwork is installed on the side face of the bearing platform steel bar, bearing platform concrete is poured, and the bearing platform formwork is dismantled after pouring is completed; brick substitute molds are built between the bottom elevation of the cushion layer of the bearing platform and the reserved steel bars at the haunching positions; frame beam columns are poured to the floor slab surface; a haunched cushion layer is poured to the bottom elevation of the floor slab; and backfilling is conducted, and a second cushion layer is poured. The wood mould and the brick substitute mould are mixed for use, that is, the brick substitute mould is adopted at the haunched position of the beam, and the wood mould is adopted on the bearing platform, so that the construction of the shallow foundation is simpler, the problem of difficulty in supporting the mould at the haunched position under the beam is solved, the labor cost is reduced, the template loss rate is reduced, and the construction progress is accelerated.
Description
technical field [0001] The invention relates to the technical field of shallow foundations, in particular to a construction method for shallow foundations. Background technique [0002] With the rapid development of the modern construction industry, the continuous updating of building construction methods, and the extensive use of new materials, in the current construction, the shallow foundation construction method is the use of brick tire membrane as a formwork or short-bracket formwork construction. The construction of the shallow foundation of the beam is extremely difficult, the concrete grades of the caps, columns and beams are inconsistent, and the concrete pouring is difficult. Contents of the invention [0003] Based on this, it is necessary to provide a shallow foundation construction method to solve the problem of difficult construction of shallow foundations with haunch beams. [0004] A shallow foundation construction method, comprising the following steps: ...
