Description
Technical field
The invention belongs to the waterproof technique field of tunneling and underground engineering, specifically, be used for deforming particularly to one
The middle buried water stop structure of the active-passive integrated sealing of seam.
Background technology
At present, it is main that tunneling and underground engineering typically uses main structure body waterproof, with the thin portion such as construction joint and movement 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 construction joint and movement 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.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is to provide a kind of for movement joint
The middle buried water stop structure of active-passive integrated sealing.
Technical solution of the present invention is as follows: the middle buried water stop structure of a kind of active-passive integrated sealing for movement joint,
There is master tape body, it is characterised in that: the integral middle at master tape body is formed with convex platform and lower convex platform, and upper and lower boss is all along main
The length direction of belt body extends, and forms cavity, be all provided with at the two ends of described master tape body width between convex platform and lower convex platform
Being equipped with side capsule, this side capsule extends along the length direction of master tape body, and side capsule protrudes from the end face of master tape body, on the top of described side capsule
Have the inlet opening with its inner space, the inner chamber of side capsule arranges the most suitable water-swellable body, at two avris capsules
Outside is all fixedly installed metal spacer, and this metal spacer extends along the length direction of master tape body.
It is the most waterproof that the present invention has waterstop master tape body, side capsule and metal spacer, and the water-swellable body in the capsule of side is met
Water expands the multiple tracks measures of preventing water such as passive sealing, uses the actively waterproof and the most waterproof mode combined, and not only applies simple
Feasible, construction quality is relatively easy to control, and by the way of multi-way prevention, water can effectively get lodged in inflow side, slow down and finish
The disadvantage of structure percolating water.
The present invention has a following twice waterproof construction:
First is actively water blockoff, waterstop master tape body, side capsule and metal spacer actively by water blocking in inflow side.
Second is the passive sealing of water-swellable body in the capsule of side, and once the water yield is relatively big, and subsoil water permeates to inside configuration,
By by the inlet opening approaching side capsule inner chamber on the capsule of side, make the water-swellable body water-swellable in the capsule of side, produce powerful expansion
Pressure, by closely connected to side capsule and concrete interface, produce bigger water pressure resistance, reaches passive stagnant water effect.
Water-swellable body is placed in the capsule of side by the present invention, is not only convenient for factory and makes, and product quality is easily guaranteed, and
Water-swellable body is protected by side capsule, and under the capsule effect of contraction of side, easily ensures the bulbs of pressure, improves waterproof effect.
The present invention applies simple possible, and one procedure realizes multi layer waterproof effect, has saved construction cost, water-swellable 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 inflow side, mixed
Xtah Crude Clay structure good endurance.
Master tape body integral middle forms upper and lower boss, in order to position in embedding distortion seam；Between convex platform and lower convex platform
The cavity formed enables boss to deform, stretches, to adapt to the needs of different distortion seam size.
Owing to the concrete of movement joint both sides is to have poured a rear flank to pour opposite side again, the metal spacer outside the capsule of side
Being unlikely to deform in concrete, locating effect is notable, it is possible to make the present invention fixed in concrete.Side capsule protrudes from master tape
The end face of body, while waterproof, also has the effect of location, to prevent the present invention from being pulled from concrete.
In order to simplify structure, it is simple to processing and fabricating, described convex platform and lower convex platform are symmetrically arranged circular arc, described sky
Chamber is circular.
The heart that outline is accumbency of described side capsule cross section, the big rostral of side capsule and the end of master tape body are linked as one
Body, the inward flange of metal spacer is sandwiched fixing by the little rostral of side capsule.The on the one hand side capsule moulding of above structure is simple, material profit
High by rate；On the other hand, side capsule is actively the most waterproof effective, and side capsule is big with metal spacer contact area, fixed,
Will not fall off.
Injecting in the capsule of side for the ease of water-swellable body, the cross section of described water-swellable body is circular.
Described inlet opening is obliquely installed, the big rostral of deflection side, the upper aperture capsule of this inlet opening, and the upper aperture of inlet opening
Peak by proximal balloon top.Above structure, just can be by the approaching side capsule of inlet opening when water level rises to higher position
Chamber, so on the one hand make use of side capsule to carry out the most waterproof as much as possible；On the other hand, water can be prevented effectively from and cover side capsule
High point, waterproof effect is notable.
Being pasted with isolating membrane on the capsule of described side, the inlet opening on the capsule of side is all covered by this isolating membrane.Isolating membrane will outward
Moisture in boundary's air and the water-swellable body isolation in the capsule of side, it is possible to avoid water-swellable body not use front inefficacy.
As preferably, described water-swellable body is made up of the swollen material of slowly water-swellable.
Beneficial effect: present invention achieves waterstop master tape body, side capsule and metal spacer actively water blockoff, the chance in the capsule of side
The passive water blockoff of water expander water-swellable, has reached multiple tracks water blockoff target, and employing is the most waterproof to combine with the most waterproof, multiple tracks
Setting up defences water blockoff, water plugging effect is good；Side capsule end-on water expander is protected and effect of contraction, can improve water plugging effect；The present invention executes
Making simple possible, can save construction cost, construction quality is relatively easy to control, by water blocking outside inflow side, and concrete structure durability
Good.
