In be kept upright and need to set fixed reinforcing bar, increase workman's amount of labour and influence lining construction work efficiency.Waterstop is buried in during construction to fall
Volt causes secondary lining circular construction joint to come to nothing to cause the tunnel disease such as chip off-falling, cracking from now on, cause the safe operation of circuit
Threaten.
Utility model content
The utility model solves the deficiencies in the prior art there is provided a kind of practical end steel formwork of Tunnel Second Lining,
Preventing tunnel-liner ring waterstop will not topple phenomenon, so as to effectively prevent that construction joint of tunnel from coming to nothing the generation of disease.
The technical scheme that the utility model is used is：A kind of practical end steel formwork of Tunnel Second Lining, including L-shaped
Chassis fixed plate, L-shaped portable plate and turning handle, the vertical panel center of the L-type chassis fixed plate are connected with half round buss I, institute
State half round buss I and be symmetrically connected with trapezoidal floor and screw rotating shaft chute board, the vertical plane of the L-shaped portable plate to both sides extension
Plate center is connected with half round buss II, and the both sides of half round buss II are connected with reaping hook flap with screw rotating shaft chute board corresponding position,
The turning handle top is connected by pin rotating shaft with reaping hook flap, and L-shaped portable plate can be overturn by pin rotating shaft, described turn
Handle bottom is connected by screw rotating shaft with the screw rotating shaft chute board in L-shaped chassis fixed plate, and screw rotating shaft can be in screw
It is movable in the slideway of rotating shaft chute board.
It is preferred that, the turning handle top has pin shaft hole I, and bottom has screw shaft hole.
It is preferred that, there is pin shaft hole II corresponding with pin shaft hole I on the reaping hook flap.
It is preferred that, the screw rotating shaft has integrally formed nut, thread section and smooth surface section.
Compared to prior art, the utility model has the advantage that：The end steel formwork can prevent tunnel-liner
Ring waterstop will not topple phenomenon guarantee waterstop construction quality to ensure the quality of tunnel-liner circular construction joint
Will not be come to nothing phenomenon, effectively prevent that construction joint of tunnel from coming to nothing the generation of disease.

Embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of practical end steel formwork of Tunnel Second Lining, structure as shown in Figures 1 to 8, including L-shaped chassis fixed plate
1st, L-shaped portable plate 2 and turning handle 9, the vertical panel center of the L-type chassis fixed plate 2 are connected with half round buss I 3, the semicircle
Sleeve I 3 is symmetrically connected with trapezoidal floor and screw rotating shaft chute board, the vertical panel of the L-shaped portable plate to both sides extension
The heart is connected with half round buss II, and the both sides of half round buss II are connected with reaping hook flap with screw rotating shaft chute board corresponding position, described
Turning handle top is connected by pin rotating shaft with reaping hook flap, and L-shaped portable plate can be overturn by pin rotating shaft, under the turning handle
Portion is connected by screw rotating shaft with the screw rotating shaft chute board in L-shaped chassis fixed plate, and screw rotating shaft can be in screw rotating shaft
It is movable in the slideway of chute board.
In the present embodiment, as shown in Figure 5, Figure 6, the top of turning handle 9 has pin shaft hole I 91, and bottom has
Screw shaft hole 92.
As shown in figure 4, having pin shaft hole II 62 corresponding with pin shaft hole I 91 on the reaping hook flap 6.
The screw rotating shaft 10 has integrally formed nut 101, thread section 102 and smooth surface section 103.
A kind of application method of the practical end steel formwork of Tunnel Second Lining：
The 1st, L row chassis fixed plates are installed two lining chassis ends are fixed it to by bolt according to the requirement of different lining thicknesses
Head.
2nd, after two lining chassis positioning, L-shaped portable plate is overturn, L-shaped portable plate is turned back and clamped by buried water stop in installation
Waterstop, and the wire rods of preprepared φ 8 (depending on length is according to sealing bandwidth) are inserted in two and half round busses respectively.
3rd, closing combination steel end die clearance, reinforcing
Wood lath is processed by gap length, wood lath is fixed using steel pipe and the fixed lumps of wood, it is ensured that end head formwork is sealed.
4th, when concrete strength reaches more than 8.0MPa, small plank is removed, chassis reclaims template and automatically strips concrete
Face.
This steel form can prevent tunnel-liner ring waterstop will not topple phenomenon ensure waterstop construction quality
So as to which the quality for ensureing tunnel-liner circular construction joint will not come to nothing phenomenon, effectively prevent that construction joint of tunnel from coming to nothing disease
Occur.
Above-described embodiment, simply preferred embodiment of the present utility model, not for limiting implementation model of the present utility model
Enclose, therefore all equivalent variations done with content described in the utility model claim, all should be included in the utility model right will
Within the scope of asking.
