Description
Technical field
The invention belongs to the waterproof technique fields of tunneling and underground engineering, specifically, more particularly to a kind of for deforming
The middle buried water stop structure of the active-passive integrated sealing of seam.
Background technology
Currently, tunneling and underground engineering generally uses based on main structure body waterproof, with the thin portions structure such as construction joint and deformation joint
Make the principle that waterproof is attached most importance to.But due to construction and technological level, concrete shrinkage and creep and waterproof material and coagulation soil nature
Energy otherness etc., causes thin portion waterproof defect occur, and the thin portions percolating water such as construction joint and deformation joint becomes current tunnel and underground
Engineering engineering problem outstanding.Tunneling and underground engineering is mostly reinforced concrete structure, and underground water invades main structure body, causes steel
Muscle corrosion, concrete deterioration, Damage Structure durability, while tunneling and underground engineering normal operation is influenced, it will also result in operation
The increase of expense.And thin portion waterproof mostly uses based on active waterproof, the pattern supplemented by passive waterproof, once active waterproof material and
Occur gap between concrete, groundwater seepage channel will be become.Therefore reinforcing thin portion waterproof becomes tunneling and underground engineering circle
Common recognition, passive waterproof also paid attention to.
Invention content
In view of the drawbacks described above of the prior art, technical problem to be solved by the invention is to provide one kind being used for deformation joint
Active-passive integrated sealing middle buried water stop structure.
Technical solution of the present invention is as follows：A kind of middle buried water stop structure of active-passive integrated sealing for deformation joint,
With master tape body, it is characterised in that：It is formed with convex platform and lower convex platform in the integral middle of master tape body, upper and lower boss is along master
Length direction with body extends, and forms cavity between convex platform and lower convex platform, is all provided at the both ends of the master tape body width direction
It is equipped with side capsule, which extends along the length direction of master tape body, and side capsule protrudes from the top surface of master tape body, on the top of the side capsule
It is provided with the inlet opening being connected to its inner cavity, compatible water-swellable body therewith is set in the inner cavity of side capsule, in two avris capsules
Outside is fixedly installed metal locating plate, which extends along the length direction of master tape body.
There is the present invention waterstop master tape body, side capsule and metal locating plate active waterproof, the intracapsular water-swellable body in side to meet
Water expands the multiple tracks measures of preventing water such as passive sealing, using active waterproof in such a way that passive waterproof is combined, not only applies simple
Feasible, construction quality is relatively easy to control, and by way of multi-way prevention, and water can effectively be got lodged in inflow side, slow down and finish
The disadvantage of structure percolating water.
The present invention has following twice waterproof construction：
First is active water blockoff, and waterstop master tape body, side capsule and metal locating plate are actively by water blocking in inflow side.
Second is the intracapsular passive sealing of water-swellable body in side, once water is larger, underground water is permeated to inside configuration,
By by the intracapsular chamber of inlet opening approaching side on the capsule of side, makes the water-swellable body water-swellable that side is intracapsular, generate powerful expansion
Pressure, side capsule and concrete interface is closely connected, larger water pressure resistance is generated, passive water-stagnating effect is reached.
Water-swellable body is placed in the capsule of side by the present invention, is not only convenient for factory's making, 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 a procedure realizes multi layer waterproof effect, saved construction cost, water-swellable body
Water-swellable does not injure master tape body ontology, and waterproof effect is easily guaranteed；Using multiple tracks water blockoff directly by water blocking in inflow side, mix
Xtah Crude Clay structure durability is good.
Master tape body integral middle forms upper and lower boss, is positioned in being stitched in order to embedding distortion；Between convex platform and lower convex platform
The cavity of formation enables boss to deform, stretch, to adapt to the needs that different distortion stitches size.
Since the concrete of deformation joint both sides is to pour the other side after having poured side again, the metal locating plate on the outside of the capsule of side
It is unlikely to deform in concrete, locating effect is notable, and the present invention can be made fixed in concrete.Side capsule protrudes from master tape
Also there is positioning in the top surface of body while waterproof, to prevent the present invention from being pulled from concrete.
In order to simplify structure, making easy to process, the convex platform and lower convex platform are symmetrically arranged arc-shaped, the sky
Chamber is circle.
The outer profile of side capsule cross section is the heart of accumbency, and the big rostral of side capsule is linked as one with the end of master tape body
Body, the small rostral of side capsule, which sandwiches the inward flange of metal locating plate, fixes.The capsule moulding of above structure one side side is simple, material profit
With rate height；On the other hand, the effect of side capsule active waterproof is good, and side capsule and metal locating plate contact area are big, fixed,
It will not fall off.
It is injected in the capsule of side for the ease of water-swellable body, the cross section of the water-swellable body is circle.
The inlet opening is obliquely installed, and the big rostral of side capsule, and the upper aperture of inlet opening are biased in the upper aperture of the inlet opening
Peak by proximal balloon top.The above structure, just can be intracapsular by inlet opening approaching side when water level rises to higher position
On the one hand chamber is utilized side capsule and carries out active waterproof as much as possible in this way；On the other hand, water can be effectively avoided to cover side capsule most
High point, waterproof effect are notable.
It is pasted with isolation film on the side capsule, which all covers the inlet opening on the capsule of side.Isolation film will be outer
Moisture in the boundary's air water-swellable body intracapsular with side is isolated, failure before water-swellable body can be avoided to be not used.
Preferably, the water-swellable body is made of the swollen material of slowly water-swellable.
Advantageous effect：The present invention realizes waterstop master tape body, side capsule and metal locating plate active water blockoff, the intracapsular chance in side
The passive water blockoff of water expander water-swellable has reached multiple tracks water blockoff target, is combined with passive waterproof using active waterproof, multiple tracks
It sets up defences water blockoff, water plugging effect is good；Side capsule end-on water expander has protection and effect of contraction, and water plugging effect can be improved；The present invention applies
To make simple possible, construction cost can be saved, construction quality is relatively easy to control, by water blocking in outside inflow side, concrete structure durability
It is good.
