In the present embodiment, the sealant is that multiple sections along tunnel radially lay wood lath successively from top to both sides
3, the one end of the wood lath 3 is fixed on the outer panels 2-1, and the other end is fitted with the preliminary bracing structure 10.
During practice of construction, by outline excavation and the design profile line of institute's construction tunnel have deviation, outer panels 2-1's is outer
Edge can not be arrived in preliminary bracing structure 10, the distance between the outward flange according to outer panels 2-1 and preliminary bracing structure 10
Processing is fitted between wood lath 3, and two neighboring wood lath 3 and is laid, it is ensured that the sealing of chassis steel end mould.
In the present embodiment, the chassis steel end mould is more than with the sealant along the gross thickness of the section radial direction in tunnel to be applied
The thickness of work Tunnel Second Lining.
When actually used, chassis steel end mould is along the disconnected of tunnel along the gross thickness of the section radial direction in tunnel with the sealant
Face diameter to the thickness of wainscot 1-1, the thickness of outer panels 2-1, the groove width of card holding trough and wood lath 3 thickness sum.
During practice of construction, because arc steel form lower edge is installed with the justified margin of the chassis web 9, it is preferred that
It is certain that the arc steel form lower edge lap of splice is that outer panels 2-1 in 230mm, and sealant and steel end mould is fixedly connected with
The lap of splice, therefore to ensure having wood lath 3 to be fitted with preliminary bracing structure 10, chassis steel end mould is with the sealant along tunnel
When the gross thickness of the section radial direction in road is more than the thickness of institute's construction tunnel secondary lining, can ensure to form institute's construction tunnel two
The Sealing formboard of secondary lining cutting, prevents spilling during concreting.
In the present embodiment, along the length direction of the arc steel form between the wainscot 1-1 and the inner arc plate 1-2
Inner reinforced plate 1-3 is disposed with, along the length side of the arc steel form between the outer panels 2-1 and the outer arc plate 2-2
To being disposed with outer gusset 2-3, it is therefore an objective to strengthen the integral rigidity of the arc steel form.
In the present embodiment, the wood lath 3 is fixedly connected with the outer panels 2-1 by angle steel 6.
During practice of construction, one end and the outer panels 2-1 of angle steel 6 are welded to connect, the other end of angle steel 6 and the wood lath 3
It is fixedly connected by the second bolt 8.
In the present embodiment, the width of the card holding trough is not more than the thickness of the middle buried water stop 5, buried sealing in making
Precision with 5 positioning, so as to ensure that the installation quality of middle buried water stop 5, it is ensured that the anti-row of institute's construction tunnel arch wall
Water effect；If thickness of the width of card holding trough more than middle buried water stop 5, in concreting, concrete can enter interior
In interval between arc plate 1-2 and outer arc plate 2-2, it is unfavorable for the form removal in later stage, and cause the waste of concrete.
In the present embodiment, middle buried water stop 5 be preferably in buried rubber fastening band.
In the present embodiment, 1/2 of the length of the card holding trough more than the width of middle buried water stop 5, it is ensured that in it is buried
The accurate positioning of waterstop 5, makes the depth of burying of the middle buried water stop 5 in the middle of construction joint two segment concrete be guaranteed, and prevents
Only Tunnel Second Lining is due to the deviation of the installation site of middle buried water stop 5, the total quality of influence institute construction tunnel.
During practice of construction, the width of the middle buried water stop 5 is 350mm, and the length of the card holding trough is 230mm.
During practice of construction, middle buried water stop 5 is arranged on and exceeds chassis ring template edge along institute's construction tunnel section
200mm and it is be arranged in parallel with chassis ring template.
As shown in Figure 4 is a kind of based on the middle buried water stop positioning Second Lining Construction method of chassis steel end mould, wraps
Include following steps：
Step one, chassis are in place：The rail of trolley traveling is laid according to surveying setting-out result, after steel rail laying is good, is opened
Dynamic chassis motor, makes chassis be located in the position for needing to carry out Second Lining Construction, locks chassis, according to design and construction drawing branch
If the ring template of chassis；
During practice of construction, spacing top iron is both provided with before and after chassis, for the position of spacing chassis, prevented in secondary lining
Cause the movement of chassis steel end mould due to the movement of chassis in block work progress, also result in the change of the position of middle buried water stop 5
It is dynamic.
Step 2, the installation of middle buried water stop and positioning：When middle buried water stop 5 is installed, first from the top position in tunnel
Put and start to install, then be installed separately from the abutment wall in tunnel, the inner arc plate 1-2 is fixed on by the 1/2 of the width of middle buried water stop 5
In the card holding trough formed with the outer arc plate 2-2；
During practice of construction, middle buried water stop 5 passes through solid by bolt between bolt and inner arc plate 1-2 and outer arc plate 2-2
Fixed connection, prevents in concreting, the quick-fried mould of middle buried water stop 5.
The installation of step 3, sealant：After the completion of middle buried water stop 5 is positioned, outward flange and tunnel according to outer panels 2-1
The distance between road preliminary bracing structure 10 size determines the thickness of sealant, and the inward flange of sealant is fixedly connected outside
On plate 2-1, the outward flange of sealant is fitted with Tunnel structure 10, and the ring template and steel end mould of chassis form tunnel
The forming panel of secondary lining in construction；
During practice of construction, arc steel form is in installation process it should be noted that adjusting, being accurately positioned, installation deviation most very much not surpasses
Cross 30mm.
Step 4, casting concrete：Concrete using mould is pumped into, make firm by ramming by symmetrical, laminated pouring, layering；
Step 5, form removal.
During practice of construction, start to unscrew middle buried water stop 5 and inner arc plate 1-2 and the outer arc plate after concreting 4h
Fixed bolt between 2-2, when concrete strength is more than more than 8.0Mpa, removes small plank 3, pull up wainscot 1-1 with it is outer
The bearing pin 4-3 of the setting between panel 2-1.
In the present embodiment, before step one construction, the installation of arc steel form is carried out：By multigroup arc outside tunnel
Steel form along the chassis both sides segmented installation successively from top to chassis, respectively by the inner face of the arc steel form
Plate 1-1 is fixedly connected with inner arc plate 1-2, outer panels 2-1 and outer arc plate the 2-2 connection of outer arcuate steel form, then will be described interior
Arc plate 1-2 is connected with the outer arc plate 2-2, and the edge of chassis web 9 is carried out into mark, by the wainscot of the arc steel form
1-1 is connected on the chassis web 9；It is fixedly connected between the arc steel form of two adjacent sections section.
During practice of construction, the arc-shaped steel model sheetinstallat is made into arc steel form on chassis web before chassis is in place
Space during installation is unrestricted, convenient to install, while being conducive to adjusting the gap of arc formwork and chassis ring template, it is ensured that
Sealing between the two.
In the present embodiment, before step 2 chassis is in place, in the chassis arc steel form and the ring template of the chassis
External coating releasing agent, is easy to form removal.
The above, is only presently preferred embodiments of the present invention, and not the present invention is imposed any restrictions, every according to the present invention
