Abstract
The invention relates to an internal-bonded water-proof technique for externally-bonded waterstop, comprising steps as follows: (1) plugging a previous seam caused by damaged embedded-type waterstop primarily to plug water; (2) chiseling a groove at the leakage place on the inner lateral side of the concrete structure at two sides of an expansion joint; (3) planting anchored reinforcement with the same height at the bottom of the groove, placing the waterstop into the groove, and ensuring that the top end of the anchored reinforcement supports the waterstop; (4) setting a template on the groove surface, two ends of the template being tightly clipped to the inner lateral surface; (5) and pouring slurry materials into the groove, and removing films to an intensity. The invention finishes procedures of bonding, filling, sealing and enhancing at a time, can greatly enhance the tensile strength to ensure a level surface upon completion.
Description
Technical field
The present invention relates to internal-bonded water-proof technique for externally-bonded waterstop.
Background technology
On underground concrete structure design, for preventing, a plurality of shrinkage joint to be set usually improve because of distortion, sedimentation structural damage is influenced than edifice differential settlement and distortion.The big abrasive rubber of good springiness, elongation per unit length or the waterstop of plastic material are adopted in the processing at shrinkage joint mostly, bury in having in the design and two kinds of external labeling types.Bury the middle part, cross section that exactly waterstop is embedded in the concrete structure in described; Described external labeling type is to be applied in underground concrete structure shrinkage joint, the settlement joint outside, and upstream face just is as figure (1).
Handle the shrinkage joint way with waterstop was to adopt chemical grouting in the past mostly, or with bolt press the rubber tile sealing, to structure heavy excavation, method such as embedding waterstop again.These methods facts have proved poor effect, the expense of taking a lot of work material, and the difficulty of processing is also big, and the ratio that give prominence at the position of processing is higher.Press the rubber tile encapsulating method with bolt, can be described as in above-mentioned several processing method reasonable one, see figure (2), the main construction sequence of this method is as follows: at first pervious seam is carried out leak stopping and tentatively water blocking is lived → cut concrete surface, both sides, shrinkage joint and expose space → usefulness between reinforcing bar → angle steel is welded on the reinforcing bar → inner perfusion waterproofing mortar → shutoff angle steel and the concrete structure and be welded in bolt on the angle steel in advance and by the steel plate press strip rubber tile compressed to seal and finish whole operations.There is following problem in the method in practice of construction:
1. the reinforcing bar in the concrete structure not necessarily just satisfies the angle steel welding requirements, also is inconvenient to carry out welding operation, and angle steel should all will one in the company of welding seal integral body up and down underground, and particularly the operation easier at top is very big;
2. the space is difficult to reach real sealing between angle steel and the concrete structure, and this just requires the rigidity of angle steel must be very big, otherwise the angle steel amount of deflection, and factors such as distortion are easy to form constuction joint and seep water, and reaches good effect in that the operation at top is just more difficult;
What 3. the bolt on the angle steel will weld is many and close, and just spacing is little, otherwise rubber tile compresses sealing very much between bolt and the bolt, just strengthen the thickness of steel plate press strip;
4. underground long-term place dampness, ironware easily gets rusty influences application life, and it is higher to handle back protuberate, brings influence to use.
Summary of the invention
The objective of the invention is to address the above problem and provide a kind of and once finish stickup, filling, sealing, strengthen operation, can strengthen tensile strength greatly, the smooth internal-bonded water-proof technique for externally-bonded waterstop in completion rear surface.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
It comprises that (1), the pervious seam that the middle buried water stop that damages is produced carry out preliminary leak stopping, live water blocking; (2) medial surface one end that is positioned at the concrete structure in the both sides, shrinkage joint is cut a hole groove; (3), plant contour anchor bar, waterstop is put into groove, and make fixedly waterstop of anchor bar at bottom portion of groove; (4), template is set, template proximate is at the medial surface of concrete structure at groove surface; (5), in groove, pour into grouting agent, reach stripping after the intensity.
Above-mentioned waterstop comprises the waterstop body, and the waterstop body is provided with a plurality of holes, is provided with lacing wire in the hole.
Above-mentioned to also being provided with steel mesh reinforcement on lacing wire and the anchor bar.
Above-mentioned two ends, hole are provided with protruding circle.
Compared with prior art, the present invention has obtained following technique effect:
1, this present invention can overcome the shortcoming of conventional practice effectively, makes full use of outer profile characteristics of pasting waterstop, pastes on the waterproofing work in it is referred to, and can carry out waterproof construction in the inboard of underground structure; Can reduce destruction and damage to greatest extent to structure concrete wall; The not outstanding wall in position after the construction completion or few outstanding; It is strong to adapt to the dilatation ability; Can resist outside upstream face higher hydraulic pressure; The grouting material can disposablely be finished bonding, filling, sealing, strengthen operation;
2, by also being provided with steel mesh reinforcement establishing on the waterstop to lacing wire with on to lacing wire and anchor bar, can further improve the anti-folding tensile strength of waterstop both sides grouting material, thereby can further improve the waterstop bearing capacity, enlarge the range of application of waterstop;
3, by being provided with protruding circle, can further improve the fastening and sealing effectiveness between lacing wire and the waterstop at the two ends, hole.
