Description
Technical field
The invention belongs to the technical fields of basement drainage system, and in particular to a kind of basement post-pouring zone underdrain terrace is applied
Work method.
Background technique
Buildings waterproof plays a significant role guarantee building normal usage function and structure service life, concerning the common people people
Raw and social harmony.Construction waterproofing engineering technical quality steps up at present, has considerably reduced engineering leakage water rate, but ground
Lower room engineering leakage is still common quality defect common in engineering.
With the development and utilization of the underground space, more and more houses are designed using integral basement, integral basement control
The method of system sedimentation is setting post-cast strip, and the setting of a large amount of post-cast strips becomes the multiple position of basement bottom board leakage, and
Once occur leakage maintaining cost it is high, calculated according to engineering practice, every meter only maintenance cost up to 1000 yuan.For two, three, four
The underground engineering of grade waterproofing grade provides that body structure surface can according to " underground waterproof engineering inspection of quality specification " GB50208-2011
There is a small amount of wet stain, but a small amount of wet stain bring terrace yin tide seriously affects the use function of basement after engineering delivery, and because of ground
Face has been constructed completion, and bring maintenance cost is very big.
Summary of the invention
Goal of the invention: present invention aims at in view of the deficiencies of the prior art, providing a kind of basement post-pouring zone underdrain
Level ground construction method, the present invention is on the basis of ne-leakage point before carrying out post empiricism, guaranteeing that terrace pours, after basement
Band coiled material drain bar underdrain method for constructing terrace is poured, there is good moisture-proof impervious effect, is further reduced basement bottom board infiltration
Leak hidden danger.
Technical solution: a kind of basement post-pouring zone underdrain method for constructing terrace of the present invention includes the following steps:
(1) preparation of construction: firstly, the trend in gutter and the position of post-cast strip are determined according to construction drawing design requirement, in conjunction with
The layout drawing of post-cast strip underdrain is drawn in gutter and the position of sump, and underdrain must not intersect with gutter and be directly communicated to catchment
Well；Then, base cleaning carried out to ground as required, do ash cake floating screed, install gutter construction, and leakage scenarios arranged
Examination is received；Finally, selecting bump height for the coiled material drain bar of≤12mm, according to drain bar before the construction of post-cast strip underdrain
Specification is cut into width >=300mm lath by modulus；
(2) snap the line indicates that underdrain moves towards: according to the post-cast strip underdrain layout drawing of drafting, in the pop-up control of post empiricism seam two sides
Line, or unilateral control line determine different underdrain system trends according to catch pit position, and underdrain system must not move towards
It is connect with original design gutter；
(3) it is laid with drain bar: the drain bar salient point cut being laid with down along control line, drain bar connection uses the overlap joint of snapping
Mode, the lap width of drain bar are at least two rows of salient point snappings；
(4) it pours fine-stone concrete: pouring fine-stone concrete on the drain bar laid, struck off using floating rule, make to fill in drain bar salient point
Full fine-stone concrete, surface carry out hair pulling treatment；After the completion of pouring, shape under the concrete fulcrum and drain bar collective effect that are formed in salient point
At underdrain and guarantee the compression strength of terrace, while reducing destruction when pouring terrace to underdrain, is convenient for finished product protection；
(5) it two side sealing of drain bar: is laid with the gap of microlith concrete plug two sides, drain bar two sides respectively in drain bar underdrain two sides
Fine-stone concrete heap it is sloping and drain bar side is blocked it is closely knit, it is same with the concrete fulcrum that pours salient point in order to simplify working procedure
When construct；
(6) terrace is poured and is conserved: floor construction is carried out afterwards for 24 hours after the completion of construction, to thin on drain bar before floor construction
Stone concrete carries out watering or covering curing；It is many to the curing time of the fine-stone concrete on drain bar if not pouring terrace in time
In 7 days.
Preferably, in the step (4), pour fine-stone concrete with a thickness of 10mm.
Preferably, in the step (1), thickness >=0.7mm of drain bar.
The utility model has the advantages that (1) it is of the invention method it is simple, utilize the salient point and drain bar collective effect of anti-paving coiled material drain bar
It forming underdrain and guarantees the compression strength of terrace, the construction technology in the present invention is simple, and worker operation is convenient, and speed of application is fast,
And can construct simultaneously with base cleaning and gutter, on the duration of a project without influence, fast, the easy to operate, cost with speed of application
Low, the advantages that serious forgiveness is high；
(2) fine-stone concrete is perfused in the present invention in the salient point of drain bar in advance, guarantees terrace intensity, does not influence the construction matter of terrace
Amount, has the function of that anti-row combines using the underdrain of this method, effectively reduces basement bottom plate rear pouring tape hidden leakage defect, subtract
Few later period maintenance cost, improves owner's satisfaction, has preferable economic benefit and social benefit；
(3) material of the invention is environment friendly and pollution-free, on environment without influence；It reduces later period terrace to do over again, economize on resources.
