Description

Tunnel Second Lining is locking plug template, plug node and method for blocking for formwork jumbo
Technical field
This scheme belongs to and in tunnel construction of tunnel, needs the template of concrete casting field, specifically a kind of Tunnel Second Lining locking plug template, plug node and method for blocking for formwork jumbo.
Background technology
In the construction of tunnel of drill bursting construction and employing composite lining, the mould that need to coordinate steel formwork jumbo to carry out secondary lining is built.At present, adopt the tunnel of drill bursting construction mostly to adopt composite lining, the secondary lining that the preliminary bracing being made up of bolt-spary supports and form concrete form both at home and abroad.Wherein, more secondary lining adopts steel formwork jumbo to carry out mould and builds, and in two lining concrete placements, a side at chassis two ends contacts with the concrete being shaped, and does not need shutoff, and an other side is faced sky, and locking plug template need be set.Because the thickness of Tunnel Second Lining changes with Grades of Surrounding Rock, and drilling and blasting method to excavate the country rock basal plane causing uneven, locking plug template cannot be made the punching block of sizing.The basic wooden model that adopts interim spelling system in constructing tunnel at present, the fixing narrow batten different in size of hoop is as locking plug template, and middle buried water stop (bar) adopts reinforcing bar to fasten at lining cutting middle part (hoop layout).
The template system of this structure is subject to the impact of existing construction technology, and the wooden assembled formwork of employing, because seam is too much, often occurs local spillage phenomenon in work progress, cause basal plane coarse, and expansion sealing strip waterproof effect is had a greatly reduced quality; And for middle buried water stop, because locking plug template is wooden structures, cannot reserve fixed card slot, can only position by reinforcing bar card is set and (adopt the paragraph of plain concrete secondary lining, still need hoop spacer bars is set), virtually increase engineering cost, and complicated construction technique, difficult quality guarantee.That is to say, waterstop (bar) erection procedure is comparatively complicated on the one hand, constuction joint contact basal plane is comparatively coarse on the one hand, cause waterproof effect variation, in operation process, often there is constuction joint water leakage defect (according to incompletely statistics, constuction joint water leakage defect has all appearred in domestic 90% tunnel).
Summary of the invention
In order to solve buried water stop in prior art (bar), difficult, installation base surface problem of rough are installed, the invention provides a kind of Tunnel Second Lining formwork jumbo steel and wood composite locking plug template, be used for improving seam quality and waterproof effect, and the plug node and the method for blocking that use this template are provided.
