Abstract

The present invention relates to the technical field of civil engineering, in particular to a cylindrical expander for civil engineering, comprising an outer cylinder assembly, an extrusion assembly, a guide frame and legs; the outer cylinder assembly includes a first cylinder body, a first expansion Blade, first upper support block, first lower support block, second cylinder body, second expansion blade, second upper support block, second lower support block, third expansion blade, third upper support block and third lower support block Supporting block; the extruding and expanding assembly includes a central shaft, a fixed supporting piece, a first supporting arm, a moving supporting piece, a second supporting arm, a supporting frame and a fourth expanding blade. Compared with the traditional method of directly inserting the expander into the soil for extrusion, the tubular expander for civil engineering provided by the present invention reduces the initial load on the expander, and can perform expansion faster and more stably The operation not only improves the quality of extrusion operation, but also saves energy consumption, reduces the risk of damage to the extruder, and prolongs the service life of the extruder.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a cylindrical expander for civil engineering. Background technique [0002] Cylindrical expander is a kind of construction equipment commonly used in the field of civil engineering technology. The extrusion operation is to use the expander to implant in the soil with a small aperture, and then use the expander to expand the hole to reach the design aperture construction technology. , has the advantages of convenient construction, no vibration, noise and pollution. The traditional cylindrical expander is directly driven into the soil by mechanical equipment for soil expansion operation, and its positioning ability is weak, which may easily cause damage to the extrusion equipment and reduce the quality of the soil expansion operation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tubular expander for civi...
