Description
Technical field
The present invention relates to a kind of active antiseepage basement shear wall and its construction technology, particularly shear wall upstream face is outer
Shear wall antiseepage drainage system and its construction technology.
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 for carrying out related waterproof layer afterwards is processed, and can carry out basement backfilling of earthwork operation after acceptance(check).This way is
Normal conditions, the life-span of the use function of general waterproof roll are about 5-20 or so, and common buildings basement agent structure sets
The meter life-span is about 40-70, even up to 100 years Important building basement Design of Main Structure life-span.Once waterproof layer is used
Disabler, carrys out waterproof by xoncrete structure itself entirely.Stay 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, and function is used, be all easily caused with 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 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
The higher area of water level, still occurs localized seepage, metope and ground humidity phenomenon.
Basement shear wall antiseepage problem be can be seen that from above-mentioned present situation extremely urgent.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.
Content of the invention
The technical problem to be solved is the shortcoming for above-mentioned prior art, is to provide one kind so as to purpose
Active antiseepage basement shear wall and its construction technology.
The present invention to achieve these goals, is adopted the following technical scheme that：
A kind of active antiseepage basement shear wall, basement are located in foundation ditch, arrange multiple sumps, draining in basement surrounding
Pipe 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 is filled with foundation ditch and in the region on the outside of basement；Backfill and the number of plies of medium coarse sand
For multilayer, and every layer of backfill is interlaced arrangement architecture with medium coarse sand, and drainpipe is located in medium coarse sand, and filter membrane is wrapped up
Drainpipe.
Further, hole is had on the drainpipe.
A kind of construction technology of active antiseepage basement shear wall：
（1）, before basement surrounding backfilling of earthwork, first backfill first element soil and be simultaneously compacted to the position of basement foundation ditch bottom,
Must in the middle of arch camber both sides have gravity flow water delivery the gradient, the gradient be not less than 0.6%, i.e., from base center along to both sides lay the gradient
Not less than 0.6%；And sump is set in basement surrounding, and water pump is disposed about in sump, so as to by ponding from sump
Middle extraction；
（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 makes which smooth,
Used as filter membrane, non-woven geotextile will disconnect laying non-woven geotextile, and leave the length of overlap joint thereon；
（3）, put drainpipe on filter membrane；The drainpipe of perisporium perforate is furnished on filter membrane, and drainpipe two ends are positioned over catchments
In well, drainpipe connects integral, and ensures the sealing of interface；
（4）, filter membrane parcel drainpipe；Drainpipe is wrapped by the filter membrane being laid on the bottom surface of gutter from both sides；
（5）, foundation ditch backfill；After drainpipe laying is finished, the less medium coarse sand of backfill clay content, substrate is backfilled to basement bottom
At plate hight degree；
（6）, backfill second element soil to the position in the middle of basement foundation ditch and be compacted, there is the slope of gravity flow water delivery middle arch camber both sides
Degree, the gradient are not less than 0.6%, i.e., be not less than 0.6% from base center along to the both sides laying gradient；And import surrounding arrange catchment
Well；
（7）, fill out blotter for the second time, spread filter membrane, the same step of way（2）；
（8）, put drainpipe on filter membrane, the same step of way（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 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% from base center along to the both sides laying gradient；And import surrounding setting sump；
（12）, fill out blotter for the third time, spread filter membrane, the same step of way（2）；
（13）, put drainpipe on filter membrane, the same step of way（3）；
（14）, filter membrane parcel drainpipe, the same step of way（4）；
（15）, foundation ditch backfill, the same step of way（5）.
Beneficial effects of the present invention：
The present invention is formed around drainage system in its basement shear wall, allows underground water and surface water to discharge on one's own initiative, so as to have
Effect has guarded against the impact of a large amount of underground water and surface water to basement shear wall, it is ensured that basement shearing is non-leakage, and subtracts
The thickness of few waterproof layer and pass, even if can also play active antiseepage in the case that waterproof layer reaches the life-span or is damaged prevent
Leakage, has reached the effect of dual guarantee.
