Description
Technical field
Municipal Construction Technique of Underground Works field is the utility model is related to, more specifically it is a kind of pre- using gas cell
Stay the structure of injected hole.
Background technology
In order to solve the urban land contradiction in short supply between the Land Demand that expands day by day, urban construction is progressively from ground
Go underground.Construction of underground structure is constructed, inevitably in the presence of substantial amounts of construction joint, movement joint, the presence of these structural joints
Often turn into the main thoroughfare of underground water seepage, underground water seepage has had a strong impact on the utilization benefit and effect of the underground space；
By taking underground subway station as an example, on the one hand these percolating waters cause the wet stain in station ground or hinder station electrical equipment to use, shadow
The normal use of subway station is rung, brings bad social influence；Another aspect seepage easily causes structure erosion, influences station knot
Structure is safe to use.
Conventional way is when concreting at present, Grouting Pipe is reserved in construction joint or deformation joint, after
When phase finds seepage, the passive grouting for water plugging of Grouting Pipe is utilized；But there is larger defect in current this mode, be primarily due to reserve
Injected hole in Grouting Pipe is often just blocked in agent structure concreting by concrete slurry, and the later stage is noted by Grouting Pipe
The leak stopping slurries entered, which may not broken through, to be blocked, and leak stopping slurries can not enter concrete wall gap by hole in Grouting Pipe
In, often spend a large amount of funds to be but unable to reach expected plugging effect.
Existing Application No. 201210253475.2, patent name are《Deformation joint seepage mud jacking is stifled draw method for repairing and mending and its
Slip casting special equipment》Disclose and open up injected hole, inserting Grouting Pipe, the stifled mode repair distortion seam for drawing bar of installation, be a kind of quilt
Dynamic repairing method, applicable elements have more limitation；
Existing Application No. 201210312967.4, patent name are《The repairerment construction method of basement deformation joint seepage》
Disclose and set up water expandable waterstop, external labeling type waterstop and open up drainage groove, the method for diversion to plash carries out ground
The seepage treatment of lower room movement joint, sealing, somewhat expensive are realized by setting up measures of preventing water, and be not suitable for construction joint etc. its
His Leakage Position.
The content of the invention
The purpose of this utility model is to provide a kind of structure that injected hole is reserved using gas cell, and slip casting effect is preferable, uses
Air bag replaces Grouting Pipe, and cost is relatively low, simple to operate.
To achieve these goals, the technical solution of the utility model is：A kind of knot that injected hole is reserved using gas cell
Structure, it is characterised in that：Inflated airbag is fixed at the construction joint of agent structure on the groove of building enclosure；Anti-stick oxidant layer applies
The gasbag outer surface close to agent structure side is overlying on, strong adhesive layer is coated on the air bag appearance away from agent structure side
Face, the air bag away from agent structure side are fixed on the waterproof layer of building enclosure or building enclosure by strong adhesive layer
On；Agent structure concreting is around air bag；When gas is extracted and between air bag and agent structure concrete in air bag
Gap when having water injection, the air bag of coating anti-stick oxidant layer, which is separated with agent structure concrete and shunk, to be gathered in coating by force
The air bag side of adhesive layer, cavity is between agent structure concrete and air bag and in agent structure concrete；Gas
Capsule diameter is equal with slip casting pipe diameter；Air bag is air bag with high intensity, and intensity is more than or equal to 0.2MPa.
In the above-mentioned technical solutions, the groove of building enclosure determines according to that need to reserve slip casting cavity diameter or air bag diameter.
It is easy to fixation balloon.
In concreting, air pressure can support chutable concrete pressure and not produce moderate finite deformation in air bag；Air bag
For flexible air-bag, minimum volume can be contracted to a direction under external force.
Anti-stick oxidant layer is coated, using anti-stick measure, treats agent structure concrete setting, makes air bag easily and agent structure
Concrete departs from, and air bag shrinks to side, just forms slip casting cavity passage；Strong adhesive layer is coated, measure is bonded using strong,
It is easy to air bag to be shunk to the side, avoids air bag from blocking opposite side, enter agent structure coagulation soil cracking beneficial to follow-up leak stopping slurries
Gap.
The utility model has the following advantages that：
(1) air bag has higher-strength, in concreting, in air bag air pressure can support chutable concrete pressure,
And do not produce moderate finite deformation；
(2) air bag side coats strong adhesive layer and is coupled with outside building enclosure, and opposite side coating anti-stick oxidant layer is with mixing
Coagulate native non-binding, air in extracting air bag and outside air bag side hydraulic pressure effect under, air bag can to side shrink extruding, be easy to shape
It is preferable into the cavity that can inject leak stopping slurries, slip casting effect；The injected hole for effectively solving traditional built-in slip casting pipe is easily blocked, noted
Starch the problem of effect difference；
(3) be not provided with Grouting Pipe, but original built-in slip casting pipe it is local it is pre-buried with Grouting Pipe with the inflation of diameter
Air bag, when reserved injected hole is shorter, gas cell surrounding smears adhesive, and air bag is directly taken out；When reserved longer slip casting
During hole, after agent structure concrete setting, balloon occlusion mouth is opened, is extracted out airbag gas using air pump, while by water
Injected along gasbag ektexine, under water injection pressure and interior vacuum double action, air bag is provided with anti-stick oxidant layer side and concrete
Come off, and air bag is provided with strong binding agent side and extruded, form slip casting cavity passage, effectively solve to reserve longer slip casting hole
When, it is difficult to the technical barrier for taking out air bag；
(4) the utility model is also applied for movement joint or leak stopping at the structure of seepage easily occurs in other；
(5) Grouting Pipe is replaced with air bag, cost is relatively low, simple to operate, strong applicability, can bring preferable economic benefit
And social benefit.
