According to the difference of thickness of tunnel linings, the position of longitudinal steel side waterstop is adjusted by thick 2 plate of steel and equal leg angle 3 It puts;The sidewall template 11 short with existing inverted arch of steel plate 2 of this fixture is welded and fixed, and steel plate 2 opens 2.5cm wide 8cm slot holes;Deng Corner angle 3 opens 21cm slot holes and carves the slot of depth 3.5cm, the second bolt and nut that steel plate 2 passes through M20*50 with equal leg angle 3 6 are adjusted, fixed waterstop position;
Steel plate 2 is connect with channel steel 4 by third bolt 8, to ensure the line style of longitudinal steel side waterstop and adjustment steel side The upper-lower position of waterstop;Steel plate 2 clamps longitudinal steel side with channel steel 4, square steel 1 by the first bolts of M20*150 and nut 5 to be stopped Water band;
Steel plate 2 is connect for 4 with channel steel by third bolt 8, to ensure the line style of longitudinal steel side waterstop and adjustment steel The upper-lower position of side waterstop.
Construction technology:Preparation of construction → surveying and locating → installation sealing carrying jig → installation waterstop → adjustable rooting sealing Band → pour inverted arch concrete → dismounting sealing rod fixture.
(1) surveying and locating
The absolute altitude of the longitudinal construction joint of releasing on supporting abutment wall in the early stage is needed before construction, needs to pass through initial stage in installation process Supporting abutment wall control point come control the absolute altitude of longitudinal construction joint and in buried rubber fastening band position.
(2) lining cutting sealing belt construction
Waterstop construction technology process:
Stopper template bores reinforced hole → wear reinforcing bar card → placement waterstop → preset fixture → alignment jig → straight sealing Blocking plate → next ring waterstop positioning is torn open with next link waterstop positioning → concrete perfusion →.
Apply method:Along lining cutting axis every boring~the reinforced hole of φ 12 no more than 0.5m.By manufactured reinforcing bar card, by treating It fills concrete side and passes through stopper template to opposite side, inside sticks into waterstop half, the other half waterstop is flat against on blocking plate. Blocking plate is removed after concrete setting, waterstop is stretched, then bar bending clamping waterstop.
Essentials for Construction Control:
1. check that nearby country rock surface there must not be apparent percolating water to pending construction joint in the range of 1m, if any then taking Necessary gear stifled (splash guard isolation) and ejectment measure.
2. pressing section circumferential direction length interception waterstop, make one whole waterstop of each construction joint, do not take overlap joint as possible, Only allowing there is left and right sides foundation of wall top to reserve connector in addition to length of material reason, overlapping splice length is not less than 30cm, And lap position is arranged on greatly across the following abutment wall position in following or internal rail top.
3. waterstop is symmetrically installed, stretching into the inner and outer dew partial width of mould must be equal, circumferentially sets two φ per 0.5m 6mm bar dowels are clamped, with ensure waterstop in entire work progress position it is correct.In arch wall waterstop must in inverted arch Embedded water stop band is connected, and should on one section of concrete, at waterstop concrete surface quality should reach even width, seam body it is vertical, ring To perforation, filling is closely knit, and appearance is bright and clean.
4. pour into a mould concrete, pay attention to the vibration compacting near waterstop, but waterstop must not be touched, prevent sealing from taking away Position.Foamed plastics positions waterstop in sealing belt construction, it is avoided to be displaced in concreting.Lining cutting demoulds Afterwards, it finds to walk mould phenomenon in construction if checking, until waterstop is made excessively to deviate center, then suitably should cut or fill up portion Divide concrete, rectify a deviation to waterstop.
2nd, inverted arch end point sealing belt construction
Waterstop construction technology process:
Fixed back-adhering waterstop → installation inverted arch lower template → put middle buried water stop → preset sealing carrying jig → Concrete is built in installation inverted arch upper former → waterstop positioning → reinforcing template →.
Apply method:Back-adhering waterstop is placed along inverted arch branch mask, inverted arch template lower part is stopped mounted on back sticking type Water band top, fixes inverted arch lower part template, buried water stop in placement, then install inverted arch upper mould, adjustment waterstop position It postpones and reinforces inverted arch template, blocking plate is removed after concrete setting, waterstop residual concrete is cleaned up.
Essentials for Construction Control:
1. there is apparent percolating water position to inverted arch, necessary gear stifled (splash guard isolation) and ejectment measure need to be taken.2. it presses Section circumferential direction length intercepts waterstop, and inverted arch waterstop does not take overlap joint as possible.3. waterstop is symmetrically installed, it is inner and outer to stretch into mould Revealing partial width must be equal.It must be close on the outside of the template of inverted arch lower part on rear side of back-adhering waterstop bracket groove, inverted arch upper mould Outside must be close on rear side of middle buried water stop bracket groove, with ensure waterstop in entire work progress position it is correct.
4. inverted arch back-adhering waterstop must be connected with back-adhering waterstop in main tunnel lining cutting, middle buried water stop is necessary With at inverted arch fill surface in buried water stop be connected, it is vertical that waterstop exposed surface quality should reach even width, seam body, circumferential Perforation, filling is closely knit, and appearance is bright and clean.
3rd, sealing rod is constructed at inverted arch fill surface
Sealing rod construction technology process:
Making special end head formwork, → preset sealing carrying jig → puts waterstop → fixation waterstop → and pours inverted arch coagulation Soil.
Apply method:Buried water stop built-in groove in being cut in inverted arch locking plug template tunnel center line both sides 5.67m positions.It faces upward After encircleing the inside and outside layer adjustment qualification of reinforcing bar, 50cm welds U-shaped steel muscle along the longitudinal direction, and the butt welding up and down of U-shaped steel muscle is prevented in inverted arch Waterstop offset when filling pours.
Essentials for Construction Control:
It 1. must not be cut off during sealing belt construction, will first should overlap, overlap with buried water stop in upper ring inverted arch junction Length is not less than 30cm, and waterstop overlap joint must be tight, must not there is gap.It extends out, prolongs along preformed groove at inverted arch plug Elongation is not less than 60cm.
Before 2. waterstop is placed, it is qualified first to adjust inverted arch reinforcement location by technical requirement, and ectonexine bar spacing is 35cm, longitudinal pitch 22cm.
3. waterstop is fixed with U-shaped steel muscle, necessary bracing wire when fixed, waterstop center should be with inverted arch fill surface weight It closes.U-shaped steel muscle presses longitudinal pitch 50cm butt welding.
4. waterstop must be installed and carry out concrete placings after fixing, when concrete is constructed using make firm by ramming pump by intermediate concrete flow slowly to Both sides.
Waterstop installs general requirements
1st, back-adhering waterstop must be connected with back-adhering waterstop in inverted arch in arch wall, and must be in same section On;In arch wall middle buried water stop must with buried water stop middle in inverted arch, inverted arch filling surface in buried water stop be connected It connects, and must be on same section.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model Protection domain within.
