Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] The invention provides a steel mold for rectangular tunnel segments, which is used for prefabricating segments and is suitable for rectangular shield construction. The prefabricated segments are transported to the construction site for assembly to form pipe joints in the tunnel. The tunnel segment steel mold of the present invention adopts a locking structure to connect each formwork, so that the connection operation between the formworks is convenient, the mold has good rigidity and strength, and the inner cavity has high precision. The hand hole mold core and the end mold are connected by a connection structure. The concentricity requirements of the connection hole on the end mold and the connection hole on the hand hole mold core are high, so the position of the positioning bolt is fixed. The precision requirements of the nuts of the ...

Abstract

The invention relates to a rectangular tunnel segment steel die. The rectangular tunnel segment steel die comprises a bottom die, side dies and end dies, wherein the bottom die, the side dies and the end dies are in enclosed connection; every two of the bottom die, the side dies and the end dies are connected and fixed through a locking structure; each locking structure comprises a limit sleeve, a first nut embedded in the limit sleeve and a first bolt matched with the first nut, the limit sleeve is fixed on the bottom die, the corresponding end die or the corresponding side die and limits rotation of the first nut, and an elastic stop ring is arranged at the end part of the limit sleeve. Templates are connected through matching of the first bolts and the first nuts, and simplicity and convenience are achieved; each first nut is embedded into the corresponding limit sleeve and is fixed through the corresponding elastic stop ring, if the first nut is damaged during use of the steel die, a new nut can be replaced after the elastic stop ring is dismounted, the operation is convenient, fast, time-saving and labor-saving, and the use of the segment steel die is not influenced.

Description

technical field [0001] The invention relates to the field of templates, in particular to a rectangular tunnel segment steel mold. Background technique [0002] In the construction of the rectangular shield, the construction method of prefabricated segment splicing is adopted, and the rectangle is divided into more than a dozen sub-sections, prefabricated in the factory, and then the sub-sections are transported to the construction site for assembly. Because each sub-section of the rectangle has a different structure, different molds need to be customized to produce the corresponding prefabricated parts, which makes the cost of prefabricated segments higher, and the flexibility of fixed-shape molds is poor. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a tunnel segment steel mold to meet the requirements of the new shield tunnel lining, to produce tunnel prefabricated segments of different sha...
