Abstract
This utility model is related to a kind of Side Template structure of the ground fissure waterproof construction in subway tunnel.Existing ground fissure water-proofing treatment mode easily produces the problems such as race mould, positioning precision and basal plane flatness deficiency in installation process.This utility model end loops week setting steel plate between tunnel double-lining outer contour and tunnel double-lining inner outline；Steel plate is spliced by more piece veneer ring, and angle steel is welded in veneer end, and angle steel is reserved screw, and adjacent veneer angle steel docks and is bolted；It is provided with adhesive waterproof coil, the seam crossing of adjacent veneer angle steel is provided with fluid sealant in the seam of adjacent angle steel docking.Steel form of the present utility model passes through Bolted angle connection, and encapsulation process is done to angle steel connecting portion, effectively ensure that and shape waterstop, the flatness of U-shaped waterstop installation base surface and installation accuracy, it is to avoid the unused probability first leaking, reducing seepage in later stage deformation process.
Description
Technical field
This utility model belongs to the waterproof technique field of subway engineering and in particular to the ground fissure in a kind of subway tunnel is prevented
The Side Template structure of water-bound.
Background technology
Ground fissure is a kind of zonal disaster geology phenomenon, is top stratum, the soil body in natural cause（Crustal motion,
Effect of water etc.）Or anthropic factor（Draw water, irrigate, excavate）Under effect, produce cracking, and ground formed certain length and
A kind of macroscopic view earth's surface breakoff phenomenon in the crack of width.Common industry and civil buildings typically take measures to keep clear, city ground
Ferrum tunnel is kept away and can not be kept away it is necessary to pass through these hidden ground fissure belts.According to the size of subway tunnel and ground fissure angle of intersection, subway tunnel
Road takes " preventing " to combine with " putting ", and based on structural measure adaptive deformation, and the ground fissure a century deflection according to prediction is pre-
Stay necessary deformation space, in ground fissure impact section, structure is carried out with segmentation, prearrangement of deformation amount seam adapts to the deformation of ground fissure, simultaneously
Take the water-proofing treatment mode of " outsourcing reinforced waterproofing layer+and shape waterstop+U-shaped waterstop " it is ensured that tying at prearrangement of deformation amount seam
Waterproof effect can be kept when structure deforms, but be also easy to produce race mould, positioning precision and basal plane flatness in installation process not
The defects such as foot.
Content of the invention
The purpose of this utility model is the Side Template structure providing the ground fissure waterproof construction in a kind of subway tunnel, it is to avoid
Waterstop causes to run mould, positioning precision and basal plane flatness deficiency in installation process, reduces the probability of later stage seepage, after minimizing
Phase maintenance and inspection quantities and expense.
The technical scheme that this utility model is adopted is：
A kind of Side Template structure of the ground fissure waterproof construction in subway tunnel it is characterised in that：
End loops week setting steel plate between tunnel double-lining outer contour and tunnel double-lining inner outline；
Steel plate is spliced by more piece veneer ring, and angle steel is welded in veneer end, and angle steel is reserved screw, and adjacent veneer docks simultaneously
It is bolted.
Put, outside tunnel double-lining outer contour interior receipts 50mm, tunnel double-lining inner outline, the control that 100mm processes as steel plate
Datum line.
Steel plate is 10mm thickness Q235 steel plate, and veneer outer length controls between 2 ~ 3m.
It is provided with adhesive waterproof coil, the seam crossing of adjacent veneer plate face is provided with sealing in the seam of adjacent angle steel docking
Glue.
This utility model has advantages below：
（1）Steel form and two lined steel muscle are attached fixing, improve and type waterstop installation accuracy, reduce and type
The fixing difficulty of waterstop.
（2）Steel form and two lined steel muscle are attached fixing, and itself has larger rigidity again, can be prevented effectively from and run mould
Produce it is ensured that the width of idio-morphosis seam reaches design requirement.
（3）Steel form passes through Bolted angle connection, and does encapsulation process to angle steel connecting portion, effectively ensure that U-shaped waterstop
The flatness of installation base surface.
（4）Steel form makes and shape and U-shaped waterstop installation accuracy are greatly improved, it is to avoid unused first leak, after reducing
The probability of seepage in phase deformation process.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A-A generalized section in Fig. 1.
Fig. 3 is B-B generalized section in Fig. 2.
In figure, 1- tunnel double-lining outer contour, 2- tunnel double-lining inner outline, 3- steel plate, 4- angle steel, 5- self-adhesion waterproof is rolled up
Material, 6- fluid sealant, 7- bolt.
Specific embodiment
With reference to specific embodiment, this utility model is described in detail.
This utility model using steel plate as template to and shape and U-shaped waterstop be fixed, can be prevented effectively from using wood
What template caused runs the shortcoming of mould, positioning precision difference and basal plane flatness deficiency, makes the waterproof effect at prearrangement of deformation amount seam on ground
It is more effective when crack is deformed.
Using thickness 10mm Q235 steel plate as the Side Template at subway tunnel ground fissure idio-morphosis seam.And shape sealing
After band installation, fixing to outer rim the corner angle end steel formwork carrying out grinding process and the auxiliary adding reinforcing bar is welded
Connect, and adopt spot welding to connect with tunnel double-lining distributing reinforcement.Side Template is divided into some pieces according to the specific size of tunnel cross-section, piecemeal
Between by the way of tying up weldering 63 × 63 × 8mm angle steel, be attached by bolt, angle steel is welded on inside Side Template.Angle steel with
Sealed using adhesive waterproof coil between angle steel, and gap is blocked using fluid sealant, prevented water in concreting process
The gap at joint that mud passes through between Side Template piecemeal flows in movement joint.
The Side Template structure of the ground fissure waterproof construction in a kind of subway tunnel that this utility model is related to, in tunnel double-lining
Ring week setting steel plate 3 between outer contour 1 and tunnel double-lining inner outline 2.50mm, tunnel is received in tunnel double-lining outer contour 1
Put, outside two lining inner outlines 2, the control datum line that 100mm processes as steel plate 3.
Steel plate 3 is spliced by more piece veneer ring, and the angle steel 4 of weldering 63 × 63 × 8mm is tied up in veneer end, and angle steel 4 is reserved 3-5
Individual screw, adjacent veneer docks and passes through bolt 7 and connects.Steel plate 3 is 10mm thickness Q235 steel plate, veneer outer length controls 2 ~
Between 3m.It is provided with adhesive waterproof coil 5, the seam crossing of adjacent veneer plate face is provided with close in the seam of adjacent angle steel 4 docking
Sealing 6, prevents seam crossing leak.
