Description

A kind of active antiseepage basement shear wall and its construction technology
Technical field
The present invention relates to the outer of a kind of active antiseepage basement shear wall and its construction technology, especially shear wall upstream face Shear wall antiseepage drainage system and its construction technology.
Background technique
After the completion of basement main structure construction, surrounding is required to do water-proofing treatment by the shear wall of upstream face, finishes The protection processing for carrying out related waterproof layer afterwards, can carry out basement backfilling of earthwork process after acceptance(check).This way is Usual situation, the service life using function of general waterproof roll are about 5-20 or so, and common buildings basement main structure is set Counting the service life is about 40-70, and the Important building basement Design of Main Structure service life is even up to 100 years.Once waterproof layer uses Disabler carrys out waterproof by concrete structure itself entirely.Stayed in work progress the construction joint position set, post-cast strip position and Meet cold seam position of construction set by construction requirement etc., if waterproof layer loses using function, is easily led to upper bit Infiltration.If facing precipitate heavy rain, in the basement for losing waterproof layer protection, it is more likely that become a big pool, Caused economic loss will be difficult to estimate, or even influences the safety of owners and use function.Currently, in underground In the design of room waterproof layer, it is three to four times waterproof rolls that waterproof layer, which is generally twice waterproof roll or even Important building, this is just It will cause a large amount of CO2Discharge, does not meet the strategic objective of China's energy-saving and emission-reduction.If meeting Spring In Southern plum rain season, underground The higher area of water level still will appear localized seepage, metope and ground humidity phenomenon.
It is extremely urgent to can be seen that basement shear wall antiseepage problem from above-mentioned status.By increasing shear wall waterproof layer Quantity not only result in environmental pollution, and it is also possible to the service life because of waterproof layer expire without meeting the requirements.So development A kind of both simple and economic basement shear wall water-impervious construction technology seems especially urgent.
Summary of the invention
The technical problem to be solved by the present invention is to be directed to the above-mentioned prior art, to be designed to provide one kind Active antiseepage basement shear wall and its construction technology.
The present invention to achieve the goals above, adopts the following technical scheme that

Further, hole is provided on the drainpipe.
A kind of construction technology of active antiseepage basement shear wall:
(1), before basement surrounding backfilling of earthwork, position and pressure of first of the element soil to basement foundation ditch bottom are first backfilled It is real, it is necessary to which that there are the hydrophobic gradient of flowing automatically in intermediate arch camber two sides, and the gradient is not less than 0.6%, i.e., are laid with slope from base center along to both sides Degree is not less than 0.6%;And in basement surrounding, sump is set, and be disposed about water pump in sump, so as to by ponding from catchmenting It is extracted out in well;
(2), blotter is filled out, filter membrane is spread;One layer of blotter is filled out on the native surface of element that backfill finishes, compacting keeps it flat It is whole, it is laid with non-woven geotextile on it as filter membrane, non-woven geotextile will disconnect, and there are overlapped length;
(3), drainpipe is put on filter membrane;The drainpipe of peripheral wall aperture is furnished on filter membrane, drainpipe both ends are placed in In sump, drainpipe connects leakproofness that is integral, and guaranteeing interface;
(4), filter membrane wraps up drainpipe;The filter membrane being laid on the bottom surface of gutter is wrapped drainpipe from both sides;
(5), foundation pit backfills;After drainpipe is laid with, the lesser medium coarse sand of clay content is backfilled, substrate is backfilled to underground Room floor level;
(6), for backfill second element soil to the position among basement foundation ditch and compacting, intermediate arch camber two sides have gravity flow hydrophobic The gradient, the gradient be not less than 0.6%, i.e., from base center along to both sides be laid with the gradient be not less than 0.6%;And it catchments in surrounding setting Well;
(7), blotter is filled out for the second time, spreads filter membrane, the same step of way (2);
(8), drainpipe, the same step of way (3) are put on filter membrane;
(9), filter membrane wraps up drainpipe, the same step of way (4);
(10), foundation pit backfills, the same step of way (5);
(11), backfill third road element is native and is compacted, it is necessary to which there are the hydrophobic gradient of flowing automatically in intermediate arch camber two sides, and the gradient is not less than 0.6%, i.e., the gradient is laid with not less than 0.6% from base center along to both sides;And sump is set in surrounding;
(12), blotter is filled out for the third time, spreads filter membrane, the same step of way (2);
(13), drainpipe, the same step of way (3) are put on filter membrane;
(14), filter membrane wraps up drainpipe, the same step of way (4);
(15), foundation pit backfills, the same step of way (5).
Beneficial effects of the present invention:
The present invention is surrounded by drainage system in its basement shear wall, and underground water and surface water is allowed initiatively to be discharged, from And effectively guarded against the influence of a large amount of underground water and surface water to basement shear wall, it ensure that basement shearing is non-leakage, and And the thickness and pass of the waterproof layer of reduction, it can be played even if waterproof layer reaches service life or the in the case where of being damaged actively anti- Leakproof is seeped, has achieved the effect that dual guarantee.
