Description
Technical field
The utility model is related to a kind of active antiseepage basement shear wall, the particularly outer shear wall of shear wall upstream face to prevent
Ooze drainage system.
Background technology
After the completion of basement main structure construction, its surrounding is required to do water-proofing treatment by the shear wall of upstream face, finishes
The protection treatment of related waterproof layer is carried out afterwards, and basement backfilling of earthwork operation can be carried out after acceptance(check).This way is
Normal conditions, the life-span of the use function of general waterproof roll is about 5-20 or so, and common buildings basement agent structure sets
The meter life-span is about 40-70, and the Important building basement Design of Main Structure life-span is even up to 100 years.Once waterproof layer is used
Disabler, carrys out waterproof by concrete structure itself entirely.Stayed in work progress set construction joint position, post-cast strip position and
Meet cold seam position of construction set by construction requirement etc., if waterproof layer loses uses function, be easily caused with upper bit
Infiltration.If facing precipitate heavy rain, the basement of waterproof layer protection is being lost, it is more likely that become a big pool,
Caused economic loss will be difficult to estimate, or even have influence on the safety of owners and use function.At present, in underground
In the waterproof layer design of room, its waterproof layer is generally twice waterproof roll, or even Important building is three to four times waterproof rolls, and this is just
Substantial amounts of CO can be caused2Discharge, does not meet the strategic objective of China's energy-saving and emission-reduction.If meeting Spring In Southern plum rain season, underground
Water level area higher, still occurs localized seepage, metope and ground humidity phenomenon.
It is extremely urgent basement shear wall antiseepage problem to be can be seen that from above-mentioned present situation.By increasing shear wall waterproof layer
Quantity not only result in environmental pollution, and it is also possible to be unsatisfactory for requiring because the life-span of waterproof layer expires.So, development
A kind of both simple and economic basement shear wall water-impervious construction technology seems particularly urgent.
Utility model content
Technical problem to be solved in the utility model is directed to the shortcoming of above-mentioned prior art, so that purpose is to provide
A kind of active antiseepage basement shear wall.
The utility model to achieve these goals, is adopted the following technical scheme that：
A kind of active antiseepage basement shear wall, basement is located in foundation ditch, and multiple sumps are set in basement surrounding,
Drainpipe two ends are positioned in sump, and drainpipe connects integral；
The basement it include basement roof, basement shear wall, basement bottom board；
Backfill and medium coarse sand are filled with region in foundation ditch and on the outside of basement；Backfill and medium coarse sand
The number of plies is multilayer, and every layer of backfill and medium coarse sand are interlaced arrangement architecture, and drainpipe is located in medium coarse sand, filter membrane
Parcel drainpipe.
Further, it is provided with hole on the drainpipe.
Its construction method is as follows：
（1）, before basement surrounding backfilling of earthwork, first backfill first element soil to basement foundation ditch bottom position simultaneously press
Real, it is necessary to which that there is the gradient of gravity flow water delivery middle arch camber both sides, the gradient is not less than 0.6%, i.e., lay slope along to both sides from base center
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
Extracted out in well；
（2）, fill out blotter, spread filter membrane；One layer of blotter is filled out in the element soil bottom surface finished in backfill, and compacting puts down it
It is whole, non-woven geotextile is laid thereon as filter membrane, non-woven geotextile will disconnect, and leave the length of overlap joint；
（3）, drainpipe is put on filter membrane；The drainpipe of perisporium perforate is furnished on filter membrane, drainpipe two ends are positioned over
In sump, drainpipe connects integral, and ensures the sealing of interface；
（4）, filter membrane parcel drainpipe；The filter membrane being laid on the bottom surface of gutter is wrapped drainpipe from both sides；
（5）, foundation ditch backfill；After drainpipe laying is finished, the less medium coarse sand of clay content is backfilled, substrate is backfilled to underground
Room floor level；
（6）, backfill second element soil to the position in the middle of basement foundation ditch and be compacted, there is gravity flow water delivery middle arch camber both sides
The gradient, the gradient be not less than 0.6%, i.e., from base center along to both sides laying the gradient be not less than 0.6%；And import surrounding setting collection
Well；
（7）, fill out blotter for the second time, spread filter membrane, the same step of way（2）；
（8）, drainpipe, the same step of way are put on filter membrane（3）；
（9）, filter membrane parcel drainpipe, the same step of way（4）；
（10）, foundation ditch backfill, the same step of way（5）；
（11）, the 3rd road of backfill element soil and be compacted, it is necessary to there is the gradient of gravity flow water delivery middle arch camber both sides, and the gradient is not less than
0.6%, i.e., it is not less than 0.6% along to the both sides laying gradient from base center；And import surrounding setting sump；
（12）, fill out blotter for the third time, spread filter membrane, the same step of way（2）；
（13）, drainpipe, the same step of way are put on filter membrane（3）；
（14）, filter membrane parcel drainpipe, the same step of way（4）；
（15）, foundation ditch backfill, the same step of way（5）.
The beneficial effects of the utility model：
The utility model is formed around drainage system in its basement shear wall, allows underground water and surface water to arrange on one's own initiative
Go out, so as to effectively guard against the influence of a large amount of underground water and surface water to basement shear wall, it is ensured that basement shearing is not permeable
Leakage, and reduce waterproof layer thickness and pass, even if can also be played in the case where waterproof layer reaches the life-span or is damaged
Active antiseepage leakproof, has reached the effect of dual guarantee.
