Description
Technical field
This utility model belongs to the waterproof technique field of tunneling and underground engineering, specifically, is used for particularly to one
The external labeling type Water stop structure of the active-passive integrated sealing of construction joint.
Background technology
At present, it is main that tunneling and underground engineering typically uses main structure body waterproof, with the thin portion such as movement joint and construction joint structure
Make the waterproof principle attached most importance to.But due to construction and technological level, concrete shrinkage and creep and waterproof material and coagulation soil nature
Can diversity etc., cause that thin portion is waterproof defect occurs, the thin portion such as movement joint and construction joint percolating water becomes current tunnel and underground
The engineering problem that engineering is prominent.Tunneling and underground engineering mostly is reinforced concrete structure, and subsoil water invades main structure body, causes steel
Muscle corrosion, concrete deterioration, Damage Structure durability, affect tunneling and underground engineering normal operation simultaneously, will also result in operation
The increase of expense.And thin portion is waterproof, and that to use the most waterproof be main is more, the most waterproof is auxiliary pattern, once actively waterproof material and
Gap occurs between concrete, groundwater infiltration passage will be become.Therefore strengthen that thin portion is waterproof becomes tunneling and underground engineering circle
Common recognition, the most waterproof have also been obtained attention.
Passive waterproof material mainly has water-swellable water-stop glue and a water-swellable sealing adhesive tape, but its be difficult to accurately to install,
It is vulnerable to damage when casting concrete, and under subsoil water repeatedly alternation of wetting and drying effect, repeatedly breathing easily causes colloid cracking
Or separate with concrete, often result in structural percolating water after using certain time limit.
Utility model content
Because the drawbacks described above of prior art, technical problem to be solved in the utility model is to provide a kind of for executing
The external labeling type Water stop structure of the active-passive integrated sealing of work seam.
Technical solutions of the utility model are as follows: the external labeling type waterstop knot of a kind of active-passive integrated sealing for construction joint
Structure, has master tape body, it is characterised in that: it is provided with the limit convex body raised up, this limit at the two ends of described master tape body width
Convex body extends along the length direction of master tape body, and it is convex that the integral middle at described master tape body end face is formed with the middle part raised up
Capsule, the convex capsule in middle part extends along the length direction of master tape body, and the top of the convex capsule in middle part is provided with opening or has inlet opening, and middle part is convex
The inner chamber of capsule is provided with the most suitable middle part convex capsule water-swellable body, the limit convex body in the convex capsule in described middle part and both sides it
Between be equipped with the convex capsule in side, the convex capsule in this side along master tape body length direction extend, the bottom of the convex capsule in side is linked as with the end face of master tape body
Integrally, the lateral wall of the convex capsule in described side has inlet opening, and the convex capsule in the most suitable side is set in the inner chamber of the convex capsule in side
Water-swellable body.
It is the most waterproof that this utility model has waterstop master tape body, the convex capsule in side and limit convex body, and side convex capsule water-swellable body is met

Outside water effectively being got lodged in main structure body, slow down the disadvantage of structural percolating water.
This utility model has following three road waterproof constructions:
First is actively water blockoff, waterstop master tape body, the convex capsule in side and limit convex body actively by water blocking outside structure.
Second is the convex capsule in side and the side convex capsule passive sealing of water-swellable body, and once subsoil water breaks through first actively water blockoff
Layer, permeates to inside configuration, when water seepage flow capsule convex to side, by Tu Nang inlet opening, side approaching side convex capsule inner chamber, makes the convex capsule in side
Water-swellable body water-swellable, produces the powerful bulbs of pressure, by closely connected to convex for side capsule and concrete interface, produces bigger water resistant
Pressure, reaches passive stagnant water effect.
3rd road is the convex capsule in middle part and the middle part convex capsule passive sealing of water-swellable body, and once subsoil water breakthrough second is passive
Water-blocking layer, permeates to inside configuration, and when water seepage flow capsule convex to middle part, opening or inlet opening by convex capsule top, middle part enter
The convex capsule inner chamber in middle part, makes the convex capsule water-swellable body water-swellable in middle part, produces the powerful bulbs of pressure, by convex for middle part capsule and coagulation
Soil Interface is closely connected, produces bigger water pressure resistance, reaches passive stagnant water effect.
Water-swellable body is placed in the convex capsule of correspondence by this utility model, is not only convenient for factory and makes, and product quality is easy to get
To ensureing, and water-swellable body is protected by convex capsule, and under convex capsule effect of contraction, easily ensures the bulbs of pressure, improves waterproof
Effect.
This utility model applies simple possible, and one procedure realizes multi layer waterproof effect, has saved construction cost, meets water swollen
Swollen body water-swellable does not injure master tape body body, and waterproof effect is easily guaranteed；Use multiple tracks water blockoff directly by water blocking in structure
Outside outline, concrete structure durability is good.
