Description

Novel built-in fitting of shield segment convenient to installation Technical Field The utility model relates to the technical field of shield segment production, in particular to a novel shield segment embedded part convenient to install. Background The shield segment is a main assembly component for shield construction, is an innermost barrier of a tunnel, bears the functions of resisting soil layer pressure, underground water pressure and some special loads, is a permanent lining structure of the tunnel by a shield method, and has the quality directly related to the integral quality and safety of the tunnel and influences the waterproof performance and durability of the tunnel; The shield segment needs its inside pre-buried internal thread sleeve again when producing for the installation of the support on the following segment, places the internal thread sleeve in the appointed position in the mould when the prefabricated pouring of segment, after the internal thread sleeve is placed, when pouring concrete, leads to the internal thread sleeve to produce the displacement easily, and then leads to follow-up mounted position dislocation. Disclosure of utility model The utility model aims to provide a novel embedded part of a shield segment, which is convenient to install, and aims to solve the problem that the pre-embedded internal thread sleeve is easy to displace and further cause dislocation of subsequent installation positions when the shield segment is poured at present. In order to solve the technical problems, the novel shield segment embedded part convenient to install comprises a fixed frame, a die assembly and an embedded part body, wherein the die assembly comprises a die groove and a bottom plate, the bottom plate can be clamped at the bottom end of the die groove in a sealing mode, the die groove is fixedly arranged at the top end of the fixed frame, a plurality of annular equally distributed bolt rods are rotatably arranged on the bottom plate, the embedded part body is sleeved on the bolt rods in a threaded mode, and a plurality of fixing plates which are longitudinally equally distributed are fixedly arranged on the outer rings of the embedded part body.
