Embodiment Construction

[0118] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0119] Such as Figure 1~2 As shown, the formwork system of this embodiment includes an inner mold system 1, an outer mold system 2 and an end mold system 3. The inner mold system 1 is located inside the pouring space of the immersed tube for positioning and fixing the inner mold formwork of the immersed tube, and the outer mold system 2 is located The outer side of the tube pouring space is used for positioning and fixing the outer formwork of the immersed tube, and the end form system 3 is located at the longitudinal end of the immersed tube pouring space and is used for positioning and fixing the end formwork of the immersed tube.

[0120] Such as Figure 1~6 As shown, the inner mold system 1 of the present embodiment includes an inner mold template, and the inner mold template includes an inner mold side mold, an inner mold upper...

Abstract

The invention relates to the technical field of immersed tube prefabrication construction, in particular to a dry dock sequential method full-section integral immersed tube prefabrication formwork system. The system comprises an inner mold system, an outer mold system and an end mold system, wherein the inner mold system is located on the inner side of an immersed tube casting space and is connected with the outer mold system located outside the immersed tube casting space into a whole through the end mold system positioned at the longitudinal end part of the immersed tube casting space, the lower end of the inner mold system is provided with an inner mold travelling support device which is used for carrying out longitudinal, transverse and vertical position adjustment on the inner mold system, and the outer mold system is an outer side formwork structure capable of being adjusted in the longitudinal direction, the transverse direction and the vertical position. The immersed tube prefabrication method has the advantages of being accurate in position adjusting, less in main body structure damage and capable of operating all weather, so that the technical problems of sequential prefabrication, adjacent operation, compact space, longitudinal long-distance travel of an ultra-large super-heavy formwork is long, being prone to deviation and the like which occur to a sequential methodare solved.

Description

technical field [0001] The invention relates to the technical field of immersed tube prefabrication construction, in particular to a full-section integral prefabricated immersed tube formwork system by the dry dock sequential method. Background technique [0002] Now there are two commonly used construction techniques for large-scale immersed tube prefabrication at home and abroad. The first type of fixed table formwork factory method prefabricated immersed tubes, that is, the prefabricated pedestal is at a fixed position, and the bound and formed steel bars are pushed and translated into the formwork by special equipment, and then the molds are closed and concrete is poured. Pushing equipment pushes the prefabricated immersed tube forward by one pipe joint, which is a typical project for the prefabrication of immersed tubes for the Hong Kong-Zhuhai-Macao Bridge. The second type of prefabrication of immersed tubes is the side-line dry dock jumping method, that is, a dry doc...
