Description
Technical field
The present invention relates to waterproof construction technology field, more particularly to underground pipe gallery waterproof technique.
Background technology
The underground waterproof engineerings such as underground pipe gallery can use a variety of waterproof constructions and construction technology, and have a variety of waterproof materials
It is available, such as rigid waterproofing, flexible water, firm, soft combination waterproof.Wherein flexible water (waterproofing industry general significance in the industry
On waterproof) be roughly divided into coating waterproofing, waterproof coiled material, film and coiled material composite water-proof again.Its water-proof mechanism is in concrete
The waterproof layer of one layer of structural outer cladding, multilayer or MULTILAYER COMPOSITE, makes to block between structure and peripheral water source, isolates, reach anti-
Water purpose.Thus when agent structure and peripheral structure deform, the integrality of waterproof layer itself and with agent structure
Tightness degree is pasted, waterproof effect can be directly affected.
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, it is 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 is overlayed, 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 on waterproof layer during reinforcing bar colligation, does protective layer, and waterproof layer and agent structure are reduced again
Integraty.
Therefore traditional underground waterproof technology, has short slab in bottom parts.Particularly from overall waterproof construction,
Due to eventually becoming the rigid structure material that have cured after the construction of its waterproof material, if as diastrophism, settle, collapse
Reason, waterproof layer follows the sinking of bed course and cracking to depart from concrete structural slab with structural slab, forms channeling water layer, causes waterproof
The global failure of structure；In addition there is seam in the lap-joint due to waterproof roll in construction, the weak link as its waterproof.
Therefore, the drawbacks of there is easy global failure or local seam crossing easy to leak using the underground waterproof engineering of above-mentioned prior art.
