Abstract

The invention belongs to the technical field of tunnel construction, and particularly to a tunnel inverted arch combined integrated template and a method for concreting construction. The invention solve the problems in the prior art that small steel dies and wood dies are respectively used for tunnel inverted arch construction for many times, labor consumption and time consumption are waste and the efficiency of construction is low. A tunnel inverted arch combined integrated template comprises an inverted arch and filling combined fixing end template, an inverted arch side arc template and a center ditch template. An inverted arch template and a filling template are machined in one body, the center ditch template is formed through one time, an excavator is used for hoisting during construction, and workers cooperate with the excavator to mount in place at one time, the time for assembling / disassembling templates by workers can be effectively shortened, and the efficiency of the construction can be raised.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a tunnel inverted arch combined integral formwork and a pouring construction method. Background technique [0002] With the rapid development of high-speed railway construction and the frequent occurrence of tunnel safety accidents, the requirements for tunnel safety steps are becoming more and more stringent, and the requirements for construction speed and quality of inverted arch closure after tunnel excavation are also getting higher and higher. The traditional combination of small steel formwork and wooden formwork is used to construct tunnel inverts in blocks and times, which is not only labor-intensive and time-consuming, but also the installation and removal of the inversion and filling end formwork, and the segmental assembly of the center ditch formwork are performed many times during the construction. , Dismantling, many procedures, slow construc...
