Description
Technical field
The present invention relates to tunnel fields, and in particular to just branch two serves as a contrast leave a blank separate structure and its external mold and buffer layer to one kind
Apply method.
Background technique
Full hall frame template can be used when Tunnel Second Lining pours, that is, full hall steel pipe scaffold is set up, then in scaffold
Upper branching standing template；Another is that, that is, using steel manufacture, have certain shapes, some strength using integral mold plate trolley
With the telescoping steel form of rigidity, poured for tunnel concrete secondary lining.Former speed of application is slow, and easily leads to template and fix
It is not in place, apply in general to the tunnel gradual change paragraph or shorter tunnel of non-standard section.It is good that the latter pours section configuration, quality
Height, but template cost is high, and material loss is larger, and every set equipment needs custom-made and generally may be only available for identical cross dimensions
In tunnel.
But both the above formwork erection pours the method for building lining just to prop up or layer structure inner wall is as external mold, when needing to create
When just propping up the detachment void space between (layer structure) and two linings (endothecium structure), both the above template casting method is unable to complete.
Summary of the invention
Two, which are just propped up, in view of the deficiencies of the prior art, the present invention proposes one kind serves as a contrast leave a blank separate structure and its external mold and buffering
Layer applies method, one of two lining of just branch leave a blank separate structure specific technical solution it is as follows: a kind of two lining of just branch is left a blank
Separate structure, it is characterised in that: including just propping up (1), buffer light layer, two lined steel tendons skeletons, two lining external molds, circumferential stress steel
Muscle (3)；
The two linings external mold includes template bearing rod (2) and two linings external mold template (4)；
The two lined steels tendons skeleton, which extends outwardly to be provided with, lengthens lacing wire (5), and the circumferential direction steel bar stress (3) is fixedly arranged on institute
It states and lengthens on lacing wire (5), template bearing rod (2) circumferential direction is installed in lengthening lacing wire (5) outer end, and the circumferential stress
Reinforcing bar (3) and the template bearing rod (2) are longitudinally uniformly distributed along tunnel；
Two lining external mold template (4) is installed on the template bearing rod (2), and the buffer light layer is arranged described
Just between branch (1) and two lining external mold template (4), at least one layer of geotextiles (6) are equipped in described just branch (1) inner surface.
To better implement the present invention, may further be: the buffer light layer is pieced together by buffering pneumatic die cushion (7) and is formed, and
The buffering pneumatic die cushion (7) is made of PE composite material, with a thickness of 1mm, length 2m, be highly 0.5m, width be 0.3m~
0.6m.Inner inflatable amount can be adjusted according to its present position using the buffering pneumatic die cushion, guarantee that just branch and two lining external molds are closely connected and slow
Qi of chong channel ascending adversely pillow can provide fixed function and additonal pressure for external mold, and lining cutting can be made to pour realization Operating Pressure.
Further: two lining external mold template (4) is PVC material.
Further: the circumferential direction steel bar stress (3) is respectively close to the outer end and inner end for lengthening lacing wire (5).
Wherein, for just propping up, two linings leave a blank separate structure external mold and buffer layer applies method: one kind is for just propping up two linings
Separate structure of leaving a blank external mold and buffer layer apply method, it is characterised in that: following steps are used,
Step 1: after the completion of the just branch (1), two layers of geotextiles (6) is laid in first branch (1) inner surface；
Step 2: building the two lined steels tendons skeleton, and the two lined steels tendons skeleton lacing wire extended outwardly be arranged it is described
It lengthens lacing wire (5)；
Step 3: the circumferential steel bar stress (3) is installed in respectively close to the lengthening lacing wire (5) inner end and outer end position
It sets, the template bearing rod (2) is installed in lengthening lacing wire (5) outer end；
Step 4: the buffering pneumatic die cushion (7) is fixedly connected with two lining external mold template (4) by binding or pin；
Step 5: after perforating to two lining external mold template (4), binding is connected on the template bearing rod (2),
And the perforation is used into rubber stoping flowing pulp plug.
The invention has the benefit that two lining external mold templates are connect by template bearing rod with two lined steel tendons skeletons, stablize
Property it is high；For two lining external mold templates on the basis of two lined steel tendons skeletons, positioning accuracy is high；This, which performs method, can guarantee that concrete lining is flat
Compliance and quality, while can realize pressure perfusion, improve concrete construction quality；Applicability is wide, is applicable to different section shape
The tunnel that formula, different length of tunnel and different concrete formations require.
Detailed description of the invention
Fig. 1 is vertical structure schematic diagram of the present invention；
Fig. 2 is the local expansion enlarged drawing of A in Fig. 1.
Specific embodiment
The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawing, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
