Abstract

The invention relates to a prefabricated model pile for a model test of a soft soil foundation strengthened by an electroosmosis combined pile. The prefabricated model pile is a prefabricated cylindrical model pile and is made of concrete, built-in steel bars are arranged in the prefabricated model pile, and four pieces of strip-shaped carbon fiber cloths are uniformly attached onto the surface; a mold for the prefabricated model pile consists of a PVC threaded pipe, a PVC threaded pipe cap and a cable tie. In order to prevent the built-in steel bars in the prefabricated model pile from translocation in the concrete pouring process, holes are punched in the PVC threaded pipe cap to fix the steel bars; in order to prevent the situations of difficult demolding of the prefabricated model pile and pile breakage in the demolding process, the mold is manufactured in a manner of splicing the short PVC threaded pipes and the long PVC threaded pipes and can be reused; the strip-shaped carbon fiber cloth for electroosmosis are closely attached onto the prefabricated model pile in the pile manufacturing process, so that secondary processing is avoided, and the time of manufacturing the model pile is saved; in addition, the prefabricated model pile is closer to a real prefabricated pile, so that an indoor model test result is closer to engineering practice.

Description

technical field [0001] The invention relates to the field of model tests for soft soil foundation treatment, in particular to a prefabricated model pile used for model tests of soft soil foundation reinforced by electroosmosis combined piles and a manufacturing method thereof. Background technique [0002] Most of the most densely populated and most economically developed areas in China are concentrated in the coastal and river areas, and most of these areas are soft soil foundations. In order to carry out large-scale development in these developed areas, soft soil foundation treatment must be carried out. Therefore, soft soil foundation treatment has always been a hot research topic. [0003] Electroosmosis consolidation method is considered to be a relatively promising soft soil foundation treatment method. The electroosmotic consolidation method can be used in combination with various soft soil foundation treatment methods such as surcharge preloading method, vacuum pre...
