Description
Technical field
The utility model relates to a kind of constructing tunnel template, relates in particular to a kind of tunnel invert backfill construction integrated template.
Background technology
Modern tunnel structure complexity, the duration is short, quality is high, and the innovation of construction technology has been proposed to higher requirement.Constructing tunnel mainly by: excavation, lining cutting, finishing three process form.The principal element that affects tunnel application life and tunnel construction cycle is by excavating and lining cutting two procedures determines.This two procedures is carried out in tunnel narrow space simultaneously, when requiring construction quality, can not interfere with each other, and this has proposed high requirement to construction method and execution control.
Current construction method is: first excavate operation in front, tunnel; Then carry out in the wings lining cutting operation.Excavation operation is selected digging mode and coordinates corresponding lining cutting mode by country rock situation.Each construction operation is alternate, sequentially carries out.The job requirements of each link guarantee plan time that will strictly closely cooperate, controls not excess budget of construction investment.
Tunnel invert and secondary lining concrete form a sealing force structure after excavation completes by tunnel, bear pressure from surrounding rock, prevent tunnel collapse, and its quality has determined the application life in tunnel.Inverted arch fill concrete plays cushioning effect, and its quality influence is to safety and the comfortableness of Vehicle Driving Cycle; Can the attached structure such as ditch and cable channel quality influence tunnel normally use.Thereby quality, the working procedure time, most important to tunnel construction of the attached structures such as inverted arch, inverted arch filling and ditch are also difficult point and the emphasis of current constructing tunnel.
In the modal bench excavation mode of current constructing tunnel as example, in constructing tunnel, inverted arch and inverted arch are filled construction process and are: waterproofing course → reinforcing bar binding is laid in the base treatment → preliminary bracing of preparation of construction → inverted arch excavation, the installation invert form → inverted arch filling concrete → inverted arch demoulding → Central drain is measured setting-out → Central drain formwork erection → inverted arch fill concrete perfusion → maintenance to intensity and met machine-walking → end.The wide approximately 6 meters of scope internal cause gradients in inverted arch middle part are less, available Manual mode, and both sides adopt form concrete.When both sides invert forms be installed installed on steel mesh reinforcement welded reinforcement support bar, less punching block is welded to invert form is installed on support bar; After inverted arch pouring concrete is complete, pull down invert form after cutting off solder joint with burning torch again when the demoulding.Above operation is complete, and with manually carrying out, workload is large, and template installation quality is restive, and every linear meter(lin.m.) need consume 40-50 kilogram of bearing bar, causes larger waste.
For solving an above-mentioned difficult problem, prior art is explored and has been tested and permitted several different methods, but all has so far various defects, is difficult to promote.For example 201310315424.2 disclosed a kind of convertible tunnel overhead arch mould plate trolley and construction methods thereof of hanging, open day is 2013.10.16, it adopts two groups independently on symmetrical travelling car, to install turnover invert form additional, carries out inverted arch and filling operation.On travelling car, be equiped with road wheel, when mobile, is just propping up on concrete surface one end, and the other end is walked on inverted arch filling face.When the demoulding, the rotation of hinge that invert form arranges on dolly, fills construction after departing from lining and exceeding filling face.From said structure and mode of occupation: 1,, because having increased dolly outside template, construction weight is larger.2, dolly template in both sides is absolute construction, when walking, walk respectively, and easy sideslip, thereby all difficulties mobile and in place, if set up guide rail, increase again workload, and dismounting inconvenience, cost is high.3, have one end road wheel to be positioned at and just prop up on concrete surface, after must moving into place before inverted arch steel mesh reinforcement is installed, personnel carry out steel mesh reinforcement installation exercise below invert form, and installing space is narrow and small and dangerous.4, soakaway trench reserved opening is easily stopped up, and inconvenience cleaning.Therefore existing invert form, owing to there are these defects, makes it be difficult to promote.
