The construction method of Novel underground room of the present utility model antiseep attachment structure, including preparation of construction → interim precipitation
Or sealing → repairing cleaning basic unit → crimping steel formability, patch water stop rubber pad → perforating → withhold steel plate, encapsulation process → dress
Sealing slip casting steel mouth → pressure testing ventilation → constant voltage slip casting → inspection seepage → secondary grouting → → incrustation of inspecting for acceptance；Specifically
Step is as follows:
1) preparation of construction
It is familiar with construction drawing, surveys job site, work out construction plan, work out construction technical schemes；Preparation construction material,
Facility, labour force etc.；
2) interim precipitation or sealing
In the case of general water slop failure, water percolating capacity is bigger, and after basement periphery backfills, level of ground water rises, for just
Typically interim sealing or precipitation is carried out by injection E-107 type polyurethane grout material, it is also possible to interim by drain in construction
By open fire carrying-off, repair cleaning basic unit for next step and lay a solid foundation；
3) cleaning basic unit is repaired
Concrete in the 300mm of both sides, gap is repaired by a, it is ensured that flat smooth, and steel plate is withheld rear without microgroove, arrives in gap
In bury no-sundries；
B as in buried deeply or damaged completely, the cleaning degree of depth is 150mm, it is ensured that stitches wide 30～40mm, exceedes width
High grade mortar to be used is repaired to reduce expense, and electric pick too small to width is opened and induced body of wall；
C crosses in gap depths (more than 150mm) and injects E-107 type polyurethane grout material, forms sealing and shape by its foaming
Become certain inspectable space；
Both sides, d gap concrete wall outer surface surpasses rheological characteristic Thief zone epoxy resin by injection S601 type and strengthens, and one
On the other hand concrete is strengthened by aspect, guarantees impervious to reach design standard.
4) crimping steel formability, patch water stop rubber pad
(condition license is available stainless by 400mm width (can be adjusted according to engineering practice) 3mm thickness galvanized steel plain sheet for a
Steel plate is more preferable) crimping becomes the stand-by plate of band V-arrangement, and find range at steel plate two outside steel plate, away from 50mm, beat the Ф 20 of spacing 180mm
Hole；
5mm thickness rubber slab is cut into the wide rubber strip of 100mm by b；
One side and the one side of rubber strip that c withholds at steel plate brush all-purpose adhesive simultaneously, are glued by rubber strip when glue is tack-free
It is attached to brush on the steel plate of all-purpose adhesive, and firmly densification is real；
5) punch in concrete structure
Measured the accurate location of steel plate hole, centered by concrete expansion joint to both sides equidistant unwrapping wire, carry out labelling, punching is deep
Degree is about 130mm, it is ensured that hole is the most accurate；
6) steel plate, encapsulation process are withheld
The steel plate fastener of band V-shaped groove is pressed onto on the expansion joint having openning hole, lengthens expansion bolt with No. 14 and will post rubber blanket
Steel plate fastener fasten solid, when in bolt hole, injecting structure glue prevents pressurization, slurry flows out in hole.Steel plate limit mouth sealant sealing
Sternly, it is ensured that during grouting under pressure, do not reveal slurry；
7) dress sealing slip casting steel mouth, slip casting
By the steel mouth of 40mm length with being welded at the V-shaped groove of galvanized steel plain sheet, connecting slip casting machine steel mouth, first pressure testing is ventilated, after
Carry out slip casting, inject Z102 type movement joint special creep slip casting glue, keep constant voltage slip casting, to constant voltage again during second steel mouth pulp
One minute, Grouting Pipe of backing off, grouting nozzle is blocked up tight with flax silk and plug.Slip casting on each grouting nozzle the most in order, thus
To last steel mouth, constant voltage three minutes；
8) seepage, secondary grouting are checked
Owing to slip casting is to be injected in the cavity between steel plate and concrete wall by Z102 type movement joint special creep slip casting glue,
Pressure is not required to too big, air may be had not empty in local during slip casting, and the creep of serosity and trickling may also be oozed
Leak source, after upon examination it is found that on the steel plate steel mouth nearest away from seepage point secondary grouting.It is full of creep glue in finally guaranteeing cavity,
By the leak stopping at the strong bond of all sites of creep glue and the material such as concrete, steel plate, never solidified the property with creep by it
The purpose of permanent leak stopping can be reached；
9) inspect for acceptance, incrustation
By i.e. checking and accepting completion after the observation ne-leakage of a period of time.With other decoration material such as PVC or aluminum-pinch after completing
Material carries out decoration process to flexible gap.
