Construction is served as a contrast using the independent prefabricated Tunneling by mining method two in arch, that is, standardizes the arch prefabricated pipe section 8 of batch production,
And only, in tunnel, avris pours the lining of side wall two 7, to solve arch prefabricated pipe section 8, pours the assembly between the lining of side wall two 7 with side
Problem, the invention also discloses above-mentioned tunnel side wall cannelure seams to pour application of the end mould in tunnel vault pipe sheet assembling,
The longitudinal joint end mould 1 is used cooperatively with side wall form 6, and longitudinal joint end mould 1 is used to be covered in the top of 6 end of side wall form, and
It is fitted closely with its upper wall surface, after pouring, longitudinal joint end mould 1 is closely affixed on the top wall surface for pouring and forming the lining of side wall two 7；Side
After 7 solidification of the lining of wall two, end mold device and side wall form 6 are removed, forms mounting groove on the top wall surface of the lining of side wall two 7,
It is mutually equipped with for the end with arch prefabricated pipe section 8, after being equipped with, the lining of side wall two 7 together forms tunnel with arch prefabricated pipe section 8
Road secondary lining；Side wall form 6 is an arc panel, consistent with the radian of tunnel-side, and height is lower than the height in tunnel,
Two sides for being placed in tunnel, side wall of the convex side towards respective side；Positioned at two side walls of two sides corresponding position
It is prefabricated pipe section 8 installation site in arch at tunnel vault between the end of template 6.
As shown in FIG. 10 and 11, the arch prefabricated pipe section for standardizing batch production has stringent size and required precision, together
When precision also poured to matched side wall cannelure seam propose to be strict with.The assembly of arch prefabricated pipe section 8 needs in place
It to serve as a contrast 7 longitudinal slots with side wall two tightly to cooperate, the mounting groove after arch prefabricated pipe section 8 assembles in place is filled with seam waterproof
Gasket 9.
For the intensity for enhancing longitudinal joint end mould 1, at longitudinal joint end, the upper wall surface of mould 1 is arranged at intervals with multiple channel mould web 1b, slot
Mould web 1b is arranged along the cross section of longitudinal joint end mould 1.Bolt company is offered on the channel mould web 1b at 1 both ends of longitudinal joint end mould
Hole 1e and dowel hole 1f are met, to realize being detachably connected for two neighboring longitudinal joint end mould 1.
Since the width of side wall form 6 is up to 12 meters, from the point of view of safety and facilitating construction, longitudinal joint end mould 1
It may be configured as more piece, more piece is successively spliced, and after splicing, the length of longitudinal joint end mould 1 is consistent with the width of side wall form 6.It spells
When connecing, it is connected by the bolt connecting hole 1e opened up on channel mould web 1b with dowel hole 1f.If not considering cost and applying
Convenience during work, theoretically and can be only with a longitudinal joint end mould 1, the length and side wall of the longitudinal joint end mould 1
The width of template 6 is consistent.When longitudinal joint end mould 1 is integral, then two end moulds support guide brackets are arranged in interval on longitudinal joint end mould 1
2 and oil cylinder engaged therewith.When longitudinal joint end mould 1 is multiple, only in the upper each setting one of two in 6 both ends of side wall form
A end mould support guide bracket 2 and oil cylinder engaged therewith.
The long arm end of end mould support guide bracket 2 is provided with the first otic placode 2a, for the ear with the corresponding position on side wall form 6
Plate is hinged, and the long-armed two opposite side wall surfaces in end are provided with support guide bracket limited block 2c, when installation, is located at corresponding end plate and limits
Position block 1d side is provided with the second otic placode 2b on long-armed side wall, hinged with one end of overturning oil cylinder 4.
Precast lining abutment wall in tunnel of the present invention overlap joint cannelure seam pours end mold device in use, in-site installation, specifically such as
Under:
Step 1: the ear that mould support guide bracket 2 will be held to pass through the corresponding position on the otic placode 2a and side wall form 6 being arranged thereon
Plate is hinged, the otic placode 2b being arranged on mould support guide bracket 2 and one end of overturning oil cylinder 4 will be held hinged.
Step 2: by the end of overturning oil cylinder support 5 with side wall formwork jumbo 11 is detachable is fixedly connected, connection position
It sets and boundary condition and 4 model of overturning oil cylinder are overturn according to end mould support guide bracket 2 determines, and by the other end of overturning oil cylinder 4 and overturning
Otic placode on cylinder support 5 is hinged.As shown in Figure 5.
Step 3: longitudinal joint end mould 1 is placed in position by human assistance, that is, it is covered in the top of 6 end of side wall form
Vertical panel 1h and slot template 1a is located at close to tunnel-side side, and the outer end of slot template 1a is closely affixed on tunnel-side.Overturning oil
4 end mould of cylinder support the long-armed of guide bracket 2 is stuck between two end mould limit plate 1d, and the outer surface long-armed guiding fagging 1c is closely pasted
It closes.
Step 4: 2 galianconism of guide bracket is supportted in cylinder body one end welding of demoulding oil jar 3 or the detachable end mould that is fixedly connected on
End, piston rod welding or the detachable upper surface for being fixedly connected on contact plate 1g by demoulding oil jar 3.After connection, indulge
Stitching end mould 1 can slide with the flexible of 3 piston rod of demoulding oil jar along the end mould support long-armed face of guide bracket 2.
When longitudinal joint end mould 1 is in place, step 1: the jacking of demoulding oil jar 3 pushes longitudinal joint end mould 1 to make that mould limit plate 1d is held to reach end
Mould supports guide bracket limited block 2c and limits transition, i.e. end mould limit plate 1d is affixed on the top of end mould support guide bracket limited block 2c；Step 2: turning over
Turn the jacking of oil cylinder 4, promote-side mould supports guide bracket 2 and pours the overturning of section exterior normal direction around the hinged axial direction of otic placode 2a, makes slot template
1a pours face and is bonded completely with 6 top wall surface of side wall form, completes the relative positioning of longitudinal joint end mould 1 and side wall form 6；The
Three steps: the side mode oil cylinder 10 of side wall formwork jumbo 11 jacks affixed side sidewall template 6, and longitudinal joint end mould 1 is complete with side wall form 6
At state positioning is finally poured, after-pouring is positioned.
After 7 solidification of the lining of side wall two, longitudinal joint end mould 1 is demoulded, and side wall seam pours device demoulding original state partial enlarged view
As shown in Figure 6.It is specific as follows:
Step 1: shrinking demoulding oil jar 3, so that slot template 1a and side wall is poured longitudinal groove profile section and demould, avoid machinery
Destruction is formed to two chemise bodies are completed, demoulding oil jar shrinks longitudinal joint end mould and demoulds state partial enlarged view such as Fig. 7 and 8 institute completely
Show.
Step 2: shrinking overturning oil cylinder 4, make longitudinal joint end mould 1, end mould support guide bracket 2 and demoulding oil jar 3 around the hinged of otic placode 2a
Axially pour the overturning of section inter normal direction, it is therefore an objective to avoid turning over the interference of 8 subsequent installation corollary equipment of arch prefabricated pipe section
It is as shown in Figure 7 to turn oil cylinder contraction longitudinal joint end mould rollover states partial enlarged view.
Step 3: contraction edge mould oil cylinder 10, makes side wall form 6 realize complete demoulding, longitudinal joint end mould 1 is with side wall form
Demoulding state partial enlarged view completely is as shown in Figure 9.After demoulding, mounting groove is formed on the top wall surface of the lining of side wall two 7, with
The end of arch prefabricated pipe section 8 is mutually equipped with.As shown in figs. 9-10, end phase when installation, in mounting groove with arch prefabricated pipe section 8
Contact position is placed with seam waterproof gasket 9.
