Abstract
A kind of bentonite adhesive for external wall waterproof layer protection board, forms bentonite slurry, wherein bentonite accounting is 6%~9%, and tackifier accounting is 0.03%~0.1%, and remaining is water by bentonite, water, tackifier by physical mixed configuration.The construction for carrying out pipe gallery fish tail and waterproof layer using the bentonite adhesive can simplify work progress, reduction construction cost, the phenomenon for avoiding during backfilling of earthwork tear waterproof roll and because adhesive consumption is indefinite use inferior materials and turn out substandard goods caused by sag of protecting coating and the phenomenon done over again.
Description
Technical field
It is more particularly to a kind of anti-for exterior wall the invention belongs to the technical field of Urban Underground structure side wall waterproofing work
The bentonite adhesive and its construction method of water layer protection plate.
Background technology
Traditional outer wall of underground structure macromolecular compounded waterproof material and its polystyrol plastic foam plate (or design requirement
Other materials) often consolidated using cement adhesive mortar or other binder materials and by gluing mode between protective layer
It is fixed.Polystyrol plastic foam plate is typically carried out during work progress in plate face and edge position in conventional art
Brushing adhesive, must try to achieve adhesive makes protective layer be firmly bonded with waterproof roll.This mode has the disadvantage that：1st, exist
During earthwork back-filling in layers, backfill can be settled, and drive protective layer to be moved to bottom, when amount of movement is excessive, meeting
Tear waterproof roll in turn results in underground agent structure and directly contact descends water, so as to cause agent structure infiltration, leak.2nd, water
Cement mortar or other binder materials dispensings are complicated, and construction cost is higher.3rd, in the later stage as the easy aging of the immersion of underground water is lost
Go effect.4th, due to smearing adhesive backers using artificial, it is possible that jerry situation, consumption is on the low side, so as to cause
The phenomenon of sag of protecting coating.
The content of the invention
It is an object of the invention to provide a kind of bentonite adhesive and its construction method for external wall waterproof layer protection board,
It can simplify work progress, reduction construction cost using the bentonite adhesive and its construction method, avoid in backfilling of earthwork process
The phenomenon of middle tear waterproof roll and because adhesive consumption is indefinite use inferior materials and turn out substandard goods caused by sag of protecting coating and the phenomenon done over again.
As above conceive, the technical scheme is that：A kind of bentonite adhesive for external wall waterproof layer protection board, its
It is characterised by：Bentonite slurry is formed by physical mixed configuration by bentonite, water, tackifier, wherein bentonite accounting is 6%
~9%, tackifier accounting is 0.03%~0.1%, and remaining is water.
The construction method of the above-mentioned bentonite adhesive for external wall waterproof layer protection board, comprises the following steps：
1. it is segmented and is required according to underground structure agent structure, complete agent structure, agent structure is in S6 grade waterproofs
On concrete layer after brushing polymer water mud, laying water-proof coiled material；
2. the bentonite slurry configured is smeared along the bonding interface and surrounding of polystyrol plastic foam plate；
3. it is in 45° angle to be kept with sawtooth trowel with plate face, presses polystyrol plastic foam plate and will be many on sawtooth trowel
Remaining bentonite slurry is reclaimed, and plate face is left the gully of some bentonite slurries；
4. polystyrol plastic foam plate is flattened on waterproof roll in place immediately；
5. polystyrol plastic foam plate is constructed from bottom to top, horizontal direction transverse direction paving, in rotation angle position, polyphenyl second
Alkene plastic foamboard answers vertical interlaced to connect；
6. the process for carrying out backfill.
Above-mentioned tackifier use pyrophosphate graft modification sodium carboxymethylcellulose CP.
The proportion requirement of above-mentioned bentonite adhesive reaches the 1.1~1.2 of mud balance.
The present invention has the advantage that and good effect：
1st, cohesive force is provided using bentonite adhesive sectional of the present invention, is polystyrene foam modeling in preliminary stage
Lateral bond power is provided between flitch protective layer and macromolecular compounded waterproof material, the vertical displacement of protective layer is not influenceed.When return
After the completion of banketing, during the late stages of developmet, with the progressively forfeiture moisture of bentonite slurry, adhesive loses cohesive force, when being backfilled to
During ground, underground water is soaked after whole pipe gallery, and bentonite slurry can retrieve moisture supplement, make its water proof anti-seepage work(
It can be played, improve pipe gallery waterproof effect.
2nd, construction technology is simple, and construction cost is low.
Brief description of the drawings
Fig. 1 is pipe gallery external wall waterproof structural representation after optimization.
In figure：1-backfill；2-polystyrol plastic foam plate；3-bentonite slurry；4-macromolecule composite water-proof
Coiled material；5-polymer water mud；6-S6 grades water-proof concrete layer.
Embodiment
A kind of bentonite adhesive for external wall waterproof layer protection board, passes through physical mixed by bentonite, water, tackifier
Configuration is formed, and the tackifier are pyrophosphate graft modification sodium carboxymethylcellulose CP.Wherein bentonite slurry preparation process
In, bentonite accounting 6%~9%, while requiring to reach mud balance more than 1.1~1.2.Then added in bentonite slurry
Tackifier CP amounts are advisable for 0.03%~0.1%.The viscosity for adding bentonite slurry after tackifier CP increases sharply, and is that system is assigned
Give excellent rheological property.
The construction of pipe gallery fish tail and waterproof layer is pasted using the above-mentioned bentonite adhesive for external wall waterproof layer protection board
Method is：
1st, required to complete agent structure according to the segmentation of underground structure agent structure, agent structure is mixed in S6 grades waterproof
Brushing polymer water mud 5 on solidifying soil layer 6, then lays macromolecular compounded waterproof material 4.
2nd, the bonding interface and surrounding using stainless steel trowel, round brush or other instruments along polystyrol plastic foam plate 2
Smear the bentonite slurry 3 configured, it is desirable to strictly smeared by full coat requirement.
3rd, it is in 45° angle to be kept with sawtooth trowel with plate face, presses polystyrol plastic foam plate 2 and will be many on sawtooth trowel
Remaining bentonite slurry 3 is reclaimed, and plate face is left the gully of some bentonite slurries 3.
4th, polystyrol plastic foam plate 2 is flattened on waterproof roll immediately and slided in place., should be soft, equal during stickup
Even extruding, and ensure flatness at any time using instrument.
5th, polystyrol plastic foam plate 2 is constructed from bottom to top, horizontal direction transverse direction paving, is often arranged plate and is answered the plate of the fissure of displacement 1/2
Long, in rotation angle position, polystyrol plastic foam plate 2 answers vertical interlaced to connect, it is ensured that what polystyrol plastic foam plate 2 was installed
Perpendicularity.
6th, the process for carrying out backfill 1.
