Abstract
The invention discloses a novel tunnel lining trolley step type plug and a method for reinforcing the plug. The step type plug has a plurality of right-angle surfaces on the concrete surface of the construction joint of the lining end, so that the flowing water path is prolonged, and the waterproof effect is obviously improved; in addition, the plugging wood board does not need to be cut repeatedly, so that the waste of materials can be effectively avoided, and the application prospect is good.
Description
Technical field
The application is more particularly to a kind of new tunnel lining trolley step plug and the reinforcement means of the plug.
Background technology
The reinforcing mode of step plug is divided into two kinds in the prior art：Reinforced on the outside of plank and plank is embedded and reinforced, its
It is poor that waterstop rebar clip fixed effect is buried in middle first method, fixture set-up time length, and waterstop bending is buried in easily causing,
In bury the waterproof effect of waterstop and have a greatly reduced quality；Second method is influenceed by first branch section out break or lining thickness change, envelope
Stifled plank needs frequently to be cut, and the waste to plank is larger, and economic and environment-friendly aspect is poor.
The content of the invention
The present invention eliminates the defects of respective, devised a kind of easy for construction, economical to integrate the advantage of above two method
The step plug of the practical belt of liner containing polyurethane, effectively improves lining construction technique.
The technical scheme is that：A kind of new tunnel lining trolley step plug, including supporting plate, stopper
Plate, closure plank, vertically polyurethane liner belt, reinforcing plank, steel pipe back rib, ring fixation steel pipe, reinforcing bar retainer ring, its
In, the blocking plate according to thickness of tunnel linings and in bury waterstop installation requirement, ring is installed on chassis panel termination in advance,
And be connected with chassis panel termination using adjustable bolt, the closure plank is fixed between steel pipe and blocking plate along section from ring
It is inserted radially into and withstands back-adhering waterstop, closure plank splices closely knit, the vertical reinforcing wood along lining cutting termination ring one by one
Plate is stupefied for being reinforced to closure plank as erecting, and the steel pipe back rib is stupefied to vertically reinforcing as horizontal stroke through reinforcing bar retainer ring
Plank is fixed, and the ring fixes steel pipe and is used for fixed closure plank, and the reinforcing bar retainer ring is welded in blocking plate in advance,
For steel pipe back rib is fixed.
Further, the blocking plate and supporting plate are fixed together by welding, or by blocking plate and supporting plate
It is set to integrative-structure.
Present invention also offers a kind of reinforcement means of above-mentioned step plug, specifically comprise the following steps：Buried in laying
Waterstop and outer patch waterstop → installation polyurethane liner belt → installation closure plank, and simultaneously with the polyurethane liner skin
Band vertically reinforces plank → installation steel pipe back rib with iron wire colligation → installation.
Compared with the prior art, beneficial effects of the present invention are as follows：
There are multiple right-angle surfaces in the step plug, extend flowing water path, waterproof in lining cutting termination construction joint concrete surface
Positive effect is lifted；It need not repeatedly be cut additionally, due to closure plank, can effectively avoid the waste of material, therefore application prospect is good
It is good.
Brief description of the drawings
Below in conjunction with the accompanying drawings and embodiment the invention will be further described：
Fig. 1 is the structural representation of the present invention；
Wherein：1st, supporting plate, 2, back-adhering waterstop, 3, closure plank, 4, polyurethane liner belt, 5, middle buried water stop,
6th, blocking plate, 7, chassis panel, 8, adjustable bolt, 9, vertically reinforce plank, 10, ring fix steel pipe, 11, reinforcing bar fixes
Ring, 12, steel pipe back rib.
Embodiment
Embodiment：It is lining trolley step plug provided by the invention with reference to shown in Fig. 1, the plug includes support
Plate 1, blocking plate 6, closure plank 3, polyurethane liner belt 4, vertical plank 9, steel pipe back rib 12, the ring reinforced fix steel pipe
10th, reinforcing bar retainer ring 11.
In the present embodiment, the blocking plate according to thickness of tunnel linings and in bury waterstop installation requirement, blocking plate carries
Front ring is connected with chassis panel termination using adjustable bolt to being installed on chassis panel termination, in bury waterstop laying position
Put away from chassis panel 15cm, the radially adjustable 5cm of regulating bolt；The closure plank size is 50cm（It is long）×20cm（It is wide）*
5cm（It is thick）, fixed from ring between steel pipe and blocking plate and be inserted radially into along section and withstand splash guard, block plank along lining cutting termination
Ring splices closely knit one by one.Plank can be repeated several times use, and the polyurethane liner belt section is right-angled trapezium, sectional dimension
（Upper bottom 6cm+ bottoms 10cm）× high 8cm, per root long 280cm, weight 22kg/ roots, customized using polyurethane material, hardness 75 can
Bending radius is not more than 200cm.It is closely connected with blocking plate that waterstop is first buried by during installation, then polyurethane liner belt loopful is pasted
Waterstop and firm with iron wire colligation is buried in tight.The advantages of being made using polyurethane material：When it is wear-resisting, durable, it can make for a long time
With and belt damages will not be caused, it is also indeformable by concrete extrusion, can arbitrarily be bent according to section radian；It is second, easily de-
Mould and non-sticky mortar, concrete surface is smooth after the demoulding；Third, it is easy to install, and waterstop can be controlled to be in new and old two lining coagulations
Position and length in soil, waterstop waterproof effect is can effectively ensure that, the vertical plank size of reinforcing is 200cm（It is long）×
20cm（It is wide）*5cm（It is thick）Plank, as it is perpendicular it is stupefied closure plank is reinforced, the steel pipe back rib uses diameter 42mm, wall thickness
3.5mm seamless steel pipe processing and fabricating, it is used as horizontal stroke stupefied through reinforcing bar retainer ring and vertical plank of reinforcing is fixed, steel pipe back rib
Ring spacing 1m arranges that the ring fixes steel pipe and uses diameter 42mm, wall thickness 3.5mm seamless steel pipe processing and fabricating, shifts to an earlier date
Cyclization to be welded along blocking plate termination, plank is blocked for fixed, the reinforcing bar retainer ring uses diameter 22mm round steel welding cyclization,
And blocking plate is welded in advance, for steel pipe back rib is fixed, arranged according to ring spacing 1m.
In the present embodiment, step is reinforced in the installation for additionally providing the chassis step plug, specifically includes following step
Suddenly：Buried in laying and outer patch waterstop → installation polyurethane liner belt → installation blocks plank, and used simultaneously with liner belt
Plank → installation steel pipe back rib is vertically reinforced in iron wire colligation → installation.
Certainly the above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow be familiar with technique
People can understand present disclosure and implement according to this, it is not intended to limit the scope of the present invention.It is all according to this hair
The modification that the Spirit Essence of bright main technical schemes is done, it should all be included within the scope of the present invention.
