Problems solved by technology

[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, but at the same time, it also has the disadvantage of being easily damaged when the load of the extruder is too large or it is used for a long time

Abstract

The present invention relates to the technical field of civil engineering, in particular to a cylindrical expander for civil engineering, including an outer cylinder assembly and an extrusion assembly; the outer cylinder assembly includes a first cylinder body, a first expansion blade, a first upper support block, the first lower support block, the second shell, the second expansion blade, the second upper support block, the second lower support block, the third expansion blade, the third upper support block and the third lower support block; The expansion assembly includes a central shaft, a fixed support, a first support arm, a moving support, a second support arm, a support frame and a fourth expansion 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, but at the same time, it also has the disadvantage of being easily damaged when the load of the extruder is too large or it is used for a long time. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tubular expander for civil engineering that can avoid damage to the expander due to excessive load or long service time. [0004] In order to solve t...
