Abstract
The invention discloses a kind of method for waterproofing of skyscraper underground pile crown, this method entirely descends the neighbouring basic unit of pile crown first, and underground pile crown does circular arc inner corner trim with basic unit junction；In underground, the neighbouring substrate surface of pile crown pastes basic unit's waterproof roll, and the periphery of underground pile crown, which pastes waterproof roll and extends to basic unit's waterproof roll, forms overlap joint；Adhesively descend waterproof roll at the top of pile crown, gap between top waterproof roll and underground pile crown anchor rib is sealed using cement base, top waterproof roll overlaps with pile crown periphery waterproof roll, and lap-joint is made hoop using waterproof roll and is sheathed on waterproof roll outer ring at the top of pile crown；Basic unit's waterproof roll and pile crown periphery waterproof roll surface laying protective layer, prevent waterproof roll from damaging.This method mode of operation is easy, it is ensured that the integrality of underground pile crown waterproof roll, avoids cracking and hollowing, the waterproof effect of underground pile crown is effectively increased, so as to ensure that the quality of skyscraper.
Description
Technical field
The present invention relates to a kind of method for waterproofing of skyscraper underground pile crown.
Background technology
It is high-rise with the high speed development of skyscraper（Super High）House, business and Large Underground Parking Space are more and more, because
This underground waterproof engineering increasingly becomes the emphasis problem that skyscraper primarily solves, the waterproof of pile crown particularly in underground engineering
Processing, effect of the position for waterproof increasingly highlight.And the water-proofing treatment of underground pile crown is past in current skyscraper
Toward being easier ignored position, and the easy coarse link of operation, therefore how stake prevented using effective method
Infiltration, which occurs, in head position has great dissemination.
Waterproof roll is mainly used for construction wall, roofing and tunnel, highway etc., play resist extraneous rainwater,
A kind of rollable flexible building material product into web-like of lower water seepage, is connected as ne-leakage between engineering foundation and building,
It is first of barrier of whole engineering waterproofing, vital effect is played to whole engineering.Its product mainly has asphalt waterproofing
Coiled material and polymer membranes.
Traditional pile head waterproofing simply pastes one layer of waterproof roll at the top of pile crown surrounding and pile crown, and waterproof roll exists
With pile crown surrounding location for paste easily cracking and hollowing, while pile crown surrounding can not make guarantor in waterproof roll stickup completion rear wall
Sheath, easily cause waterproof roll damaged in next procedure reinforcement construction, such as produced in mass concrete of basement foundation plate
Contraction fissure just occurs at pile crown, then easily causes the situation of bottom plate infiltration, had a strong impact on the quality of skyscraper.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of method for waterproofing of skyscraper underground pile crown, we
Method mode of operation is easy, it is ensured that the integrality of underground pile crown waterproof roll, avoids cracking and hollowing, effectively increases underground pile crown
Waterproof effect, so as to ensure that the quality of skyscraper.
In order to solve the above technical problems, the method for waterproofing of skyscraper underground of the present invention pile crown comprises the following steps：
Step 1: entirely descending the neighbouring basic unit of pile crown using cement mortar, the rough and uneven in surface place of neighbouring basic unit, underground pile are repaired
Head adjacent to basic unit junction with doing circular arc inner corner trim；
Step 2: the neighbouring substrate surface in underground pile crown pastes basic unit's waterproof roll, waterproof volume is pasted on the periphery of underground pile crown
Material and extend to basic unit waterproof roll and form overlap joint, pile crown periphery waterproof roll is located at the top of basic unit's waterproof roll；
Step 3: adhesively descending waterproof roll at the top of pile crown, the gap between top waterproof roll and underground pile crown anchor rib is adopted
Sealed with cement base, waterproof roll overlaps with pile crown periphery waterproof roll at the top of pile crown, and lap-joint uses the wide waterproof rolls of 50mm
Hoop is made and is sheathed on waterproof roll outer ring at the top of pile crown；
Step 4.Basic unit's waterproof roll and pile crown periphery waterproof roll surface laying protective layer, prevent waterproof roll from damaging.
Further, the diameter of the circular arc inner corner trim is more than 50mm.
Further, the lap of splice of pile crown periphery waterproof roll and basic unit's waterproof roll is more than 100mm.
Because the method for waterproofing of skyscraper underground of the present invention pile crown employs above-mentioned technical proposal, i.e. this method is flat first
The neighbouring basic unit of pile crown under site preparation, underground pile crown do circular arc inner corner trim with basic unit junction；The neighbouring substrate surface of pile crown in underground
Basic unit's waterproof roll is pasted, the periphery of underground pile crown, which pastes waterproof roll and extends to basic unit's waterproof roll, forms overlap joint；It is viscous
Underground pile overhead waterproof roll is pasted, the gap between top waterproof roll and underground pile crown anchor rib is sealed using cement base,
Top waterproof roll is overlapped with pile crown periphery waterproof roll, and lap-joint is made hoop and be sheathed at the top of pile crown using waterproof roll to be prevented
Water coiled material outer ring；Basic unit's waterproof roll and pile crown periphery waterproof roll surface laying protective layer, prevent waterproof roll from damaging.We
Method mode of operation is easy, it is ensured that the integrality of underground pile crown waterproof roll, avoids cracking and hollowing, effectively increases underground pile crown
Waterproof effect, so as to ensure that the quality of skyscraper.
Brief description of the drawings
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings：
Fig. 1 is the method for waterproofing schematic diagram of skyscraper underground of the present invention pile crown.
Embodiment
Embodiment is as shown in figure 1, the method for waterproofing of skyscraper underground of the present invention pile crown comprises the following steps：
Step 1: entirely descending the neighbouring basic unit 2 of pile crown 1 using cement mortar, the rough and uneven in surface place of neighbouring basic unit 2, ground are repaired
Lower pile crown 1 adjacent to the junction of basic unit 2 with doing circular arc inner corner trim；
Step 2: in the surface mount basic unit waterproof roll 3 of neighbouring basic unit 2 of underground pile crown 1, the periphery of underground pile crown 1, which is pasted, prevents
Water coiled material 4 and extend to basic unit's waterproof roll 3 and form overlap joint, pile crown periphery waterproof roll 4 is located at the upper of basic unit's waterproof roll 3
Side；
Step 3: adhesively descend the top waterproof roll 5 of pile crown 1, the seam between top waterproof roll 5 and the anchor rib of underground pile crown 1
Gap is sealed using cement base, and waterproof roll 5 overlaps with pile crown periphery waterproof roll 4 at the top of pile crown, and lap-joint is wide anti-using 50mm
Water coiled material is made hoop 6 and is sheathed on the outer ring of waterproof roll 5 at the top of pile crown；
Step 4.Basic unit's waterproof roll 3 and the surface of pile crown periphery waterproof roll 4 laying protective layer 7, prevent waterproof roll from damaging.
Preferably, the diameter of the circular arc inner corner trim is more than 50mm.
Preferably, the lap of splice of pile crown periphery waterproof roll 4 and basic unit's waterproof roll 3 is more than 100mm.
This method technological principle is simple, is easy to field worker to operate, and waterproof effect is good, can effectively ensure that underground pile crown is prevented
The integrality of water coiled material, cracking and hollowing are avoided, so as to ensure that the quality of skyscraper.
