Description
Technical field
The program belongs to the template field needing concrete casting in tunnel construction of tunnel, specifically a kind of Tunnel Second Lining formwork jumbo locking plug template, plug node and method for blocking.
Background technology
Adopt in the construction of tunnel of composite lining at drill bursting construction, need the mould coordinating steel formwork jumbo to carry out secondary lining to build.At present, the tunnel of drill bursting construction is adopted mostly to adopt composite lining, the secondary lining that the preliminary bracing be namely made up of bolt-spary supports and form concrete form both at home and abroad.Wherein, secondary lining many employings steel formwork jumbo carries out mould and builds, and in two lining concrete placements, the side at chassis two ends contacts with the concrete be shaped, and do not need shutoff, sky is faced in side in addition, need arrange locking plug template.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 caused uneven, locking plug template cannot make the punching block of sizing.The basic wooden model adopting interim spelling system in current constructing tunnel, hoop fixes narrow batten different in size as locking plug template, and middle buried water stop (bar) then adopts reinforcing bar to fasten in the middle part of lining cutting (hoop layout).
The template system of this structure by the impact of existing construction technology, the wooden assembled formwork of employing due to seam too much, often occur local spillage phenomenon in work progress, cause basal plane coarse, expansion sealing strip waterproof effect is had a greatly reduced quality; And for middle buried water stop, because locking plug template is wooden structures, fixed card slot cannot be reserved, can only position by arranging reinforcing bar card and (adopt the paragraph of plain concrete secondary lining, still need and hoop spacer bars is set), virtually add engineering cost, and complicated construction technique, difficult quality guarantee.That is, waterstop (bar) erection procedure is comparatively complicated on the one hand, constuction joint contact basal plane is comparatively coarse on the one hand, waterproof effect is caused to be deteriorated, constuction joint water leakage defect (according to incompletely statistics, constuction joint water leakage defect has all appearred in the tunnel of domestic 90%) is often there is in operation process.
Summary of the invention
In order to solve buried water stop in prior art (bar), difficult, installation base surface problem of rough is installed, the invention provides a kind of Tunnel Second Lining formwork jumbo steel and wood composite locking plug template, for improving seam quality and waterproof effect, and provide the plug node and method for blocking that use this template.
