Description

Technical Field

[0001] The invention relates to the technical field of box-type transformer installation, and in particular to a casting device for box-type transformer installation construction in soft soil layers. Background Art

[0002] Soft soil refers to the soil layer that is thickened, has high plasticity and low shear strength in terms of soil mechanical properties. Soft soil is mostly caused by long-term water infiltration or soil deformation caused by load. Soft soil is common in river alluvial plains, lakes, swamps, etc., and can also appear in rivers, coasts, dams, etc.

[0003] When building a box-type transformer foundation on a soft soil layer, if there is an interruption in the pouring process, the poured part will sink in the soil layer due to gravity during the interruption, which may cause deformation of the concrete structure under the soil layer and affect the integrity and stability of the structure when pouring again. During the pouring process, large stones passing through the conduit may cause the conduit to be blocked. The blocked conduit needs to be cleaned immediately, which will cause the pouring to be interrupted. Summary of the invention
