Pouring mold and pouring method for gypsum shield segment model

Abstract

The invention provides a pouring mold and a pouring method for a gypsum shield segment model. The pouring mold comprises an upper cover plate, a lower cover plate, an inner mold body, an outer mold body and cover plate fixing bolts, wherein the upper cover plate and the lower cover plate are arranged in parallel up and down; the inner mold body and the outer mold body are both vertically fixed between the upper cover plate and the lower cover plate, the inner mold body is sleeved with the outer mold body, the inner mold body and the outer mold body are arranged in a spaced mode, and a gypsum pouring area is formed between the inner mold body and the outer mold body; and the upper cover plate and the lower cover plate are fixedly connected together through the cover plate fixing bolts. According to the pouring mold, the inner mold body and the outer mold body are arranged between the upper cover plate and the lower cover plate, the gypsum pouring area is formed between the inner mold body and the outer mold body, and the upper cover plate and the lower cover plate are fixed through the cover plate fixing bolts, so that molding of the gypsum shield segment model is ensured, refined simulation of a gypsum shield segment is realized, and the mechanical behavior characteristics of the segment are fully researched; and the structure is fine, operation is feasible, the test result can be real and reliable, adjustment can be carried out according to actual design, and effective guidance can be provided for actual engineering construction.

Description

technical field [0001] The invention belongs to the technical field of tunnel engineering structure moulds, in particular to a gypsum shield segment model pouring mold and a pouring method. Background technique [0002] In recent years, with the rapid development of urban rail transit systems, a large number of urban subway tunnels are facing the challenge of complex geological conditions. More attention needs to be paid to research on tunnel structures to ensure the safety of subway operations in the later stage. Due to the characteristics of low risk, short construction period and low cost, subway shield tunnels are becoming more and more popular. In order to study the influence of complex geological conditions on subway shield tunnels and understand the mechanical behavior characteristics related to the structure, indoor scale model test research is often required in the early stage of construction; due to the easy selection of gypsum materials and the convenience of mode...
