Description
Technical field
The utility model is related to waterproof construction technology field, more particularly to subway, underground piping, tunnel, underground pipe gallery,
The water-proof technology of underground projects such as lower garage, underground antiaircraft facility.
Background technology
Underground waterproof engineering can use a variety of waterproof constructions and construction technology, and have that a variety of waterproof materials are available,
Such as rigid waterproofing, flexible water, firm, soft combination waterproof.Wherein flexible water (waterproof of waterproofing industry in the industry in general sense)
Coating waterproofing, waterproof coiled material, film and coiled material composite water-proof are roughly divided into again.Its water-proof mechanism is wrapped outside concrete structure
One layer, the waterproof layer of multilayer or MULTILAYER COMPOSITE are covered, makes to block between structure and peripheral water source, isolate, reach waterproof purpose.Thus
When agent structure and peripheral structure deform, the integrality of waterproof layer itself and close journey is pasted with agent structure
Degree, can directly affect waterproof effect.
Compare the waterproof measure of main flow at present, be that so-called skin-type waterproof is formed outside concrete structure.It is such as wet
Spread self-adhesive coiled material, pre-installed and inverted adhered, uncured compound with coiled material, etc..But with regard to current present situation, wall face and top plate accomplish skin-type
Waterproof is easier to accomplish, waterproof layer is easier with regard to that can accomplish to combine closely with structural slab.But for the bottom plate of underground engineering
But it is difficult to accomplish.Reason is that the waterproof layer of bottom plate is bonded with concrete cushion mostly, and is bonded with concrete structure,
Full encirclement truly, skin-type waterproof can not be formed.After structural slab construction, if the water and soil migration under bottom plate, or
Person's other factors cause concrete cushion to sink or ftracture, then waterproof layer can be damaged, due to waterproof layer and structural slab
It is that physics overlays, it is easy to which the sinking and cracking for following bed course depart from concrete structural slab, form channeling water layer.Deposited in structural slab
Seepage occurs in the case of defect.Even using relatively good pre-installed and inverted adhered technique is combined, difficulty of construction is also larger, does not do
Protective layer directly easily injures waterproof layer in reinforcing bar colligation on waterproof layer, does protective layer, reduces waterproof layer and agent structure again
Integraty.
Therefore traditional underground waterproof technology, has short slab in bottom parts.Particularly from the waterproof construction of entirety,
The rigid structure material that have cured is eventually become after being constructed due to its waterproof material, if as diastrophism, settles, collapse
Reason, waterproof layer follow the sinking of bed course and cracking to depart from concrete structural slab, form channeling water layer, cause waterproof with structural slab
The global failure of structure；In addition there is seam in the lap-joint due to waterproof roll in construction, turn into the weak link of its waterproof.
Therefore, the drawbacks of easy global failure or local seam crossing easy to leak being present using the underground waterproof engineering of above-mentioned prior art.
