Description
Technical field
It the utility model is related to the diaphram wall field of engineering technology in foundation pit enclosure structure, and in particular to one kind is provided with
The diaphragm wall I-shaped steel joint of water expandable waterstop.
Background technology
Subway station and basement in high rise building construction needs perform vertical soil-baffling structure, vertical soil-baffling structure form at present
Have drilled pile, diaphram wall, the stake of SMW engineering methods, steel sheet pile, cement mixing wall etc., when foundation ditch is relatively deep, soil response intensity compared with
It is low, when water level is higher, there is structure building on foundation ditch periphery, vertical soil-baffling structure uses diaphram wall mostly.Diaphram wall edge
Foundation ditch periphery divides wall section to apply, and typically first performs a phase diaphram wall section, waits a phase diaphram wall intensity to reach and sets
After counting intensity, then the second stage of diaphram wall section is performed, work is provided between a phase diaphram wall section and the second stage of diaphram wall section
Word steel joint, cross steel plate joint or fore shaft pipe joint etc..
Cross steel plate joint is made up of cross steel plate and slide type joint case, when to the integral rigidity or anti-of diaphram wall
Used when being impregnated with particular/special requirement, its advantage has：1) be provided with steel plate among joint, increase permeable blind ditch, leakage performance compared with
It is good；2) shear behavior is preferable；Its shortcoming has：1) process is more, and construction is complicated, and difficulty is larger；2) brush wall and removing wall section side wall mud
Slurry has certain difficulty；3) anti-bending strength is undesirable；4) steel plate dosage in joint is more, and cost is higher.
When diaphram wall uses I-shaped steel joint, after the second stage of diaphram wall section grooving, it is necessary to I-steel web
Brush wall skin process native clearly is carried out with wing plate.When in theory, using I-shaped steel joint, underground continuous wall connector is not in percolating water
Problem.But in Practical Project, often there is percolating water in underground continuous wall connector, and joint percolating water can cause foundation ditch periphery place
Level of ground water declines and surrounding buildings settlement cracking.So often also need to perform additionally on the outside of underground continuous wall connector
Measures of preventing water (for example, mixing pile, high-pressure rotary jet grouting pile), perform extra measures of preventing water will certainly increase the duration and increase engineering
Cost.If part of the diaphram wall as underground agent structure, it is necessary to permanent durable, the overall ne-leakage of structure.Ground
The wall of lower diaphragm wall each unit groove section can meet design requirement, form the intersegmental attachment structure of the unit groove of diaphram wall
It is diaphram wall system key core link.It is if current using diaphram wall as agent structure exterior wall, it is necessary in joint
Position performs buttress and measures of preventing water, increases construction costs.
Diaphragm wall I-shaped steel joint percolating water is caused to have the reason for following aspect：1) web of I-steel and wing plate wall are local
Mudcake is stained with, the clear mud of brush wall has mass defect；2) continuous wall connector bending resistance is low, the second stage of continuous wall concrete and I-shaped
Steel wall has bonding, and adhesive strength is relatively low, joint both sides pit earthwork excavate and support set up it is inconsistent easily cause I-steel with
Ftractureed between concrete；(3) course of hardening can produce contraction, and gap can be produced between I-steel and concrete.Therefore,
Continuous wall connector seepage is solved, it is necessary to improve from the following aspect：1) the raising clear shale amount of I-shaped steel brush wall, but I-shaped steel brush
The clear mud of wall is carried out under water, can not be checked and be monitored；2) bending resistance improved between steel letters steel and the second stage of continuous concrete is strong
Degree；3) measures of preventing water is taken between I-steel and concrete.
The seam of diaphragm wall I-steel and its both sides concrete is equivalent to the construction joint in underground engineering structure, underground work
Journey waterproof technique specification (GB50108-2008) suggests that cut and cover method Underground Construction seam water proof structure form has：1) water-swellable
Sealing rod；2) external labeling type waterstop；3) buried water stop in；4) waterproof mortar is smeared outside；5) water-repellent paint is applied outside；6) cement base is oozed
Saturating crystalline waterproof coating；7) built-in slip casting pipe.It is one-level for classification of waterproof, 2 kinds should be selected in constructed above.External labeling type
Waterstop, waterproof mortar, the outer water-repellent paint and cement based penetration crystallization type water proofing paint etc. of applying are smeared outside due to continuous wall construction
Skill, diaphragm wall I-steel joint waterproofing is not suitable for it, cross steel plate joint is equivalent to middle buried water stop.
Hydro-expansive rubber has more remarkable characteristic and advantage compared with General Purpose Rubber, and this kind of rubber produces 2-3 after water is met
Dilatancy again, and all irregular surfaces, hole and gap full of seam, while huge contact is produced, it is thorough
Bottom prevents seepage.When seam or construction joint are subjected to displacement, and cause gap beyond the elastic range of material, plain edition rubber water-proof
Material then loses sealing effect, and the material can also be by water swelling come sealing.Leak stopping is used as using hydro-expansive rubber
Hermetic seal material, not only dosage is saved, but also can be eliminated general elastomeric material and be caused elastic fatigue because of excessive compression
The characteristics of, make waterproof effect more reliable.
If the seam of continuous wall connector I-steel and concrete installs water expandable waterstop, water expandable waterstop
Meeting water will be expanded, and 2-3 times of dilatancy is produced after meeting water, and be full of all irregular surfaces, hole and the gap of seam,
Huge contact is produced simultaneously, thoroughly prevents seepage.But the seam of I-steel and the second stage of continuous wall concrete, no
Water expandable waterstop can be installed as stitching open cut Underground Construction, because the second stage of diaphragm wall foundation trench is cut the earth and I-shaped steel brush
Wall can damage water expandable waterstop, and from I-steel insert a phase diaphragm wall foundation trench to the second stage of continuous wall concrete pour when
Between be up to more than 10 days, water expandable waterstop can before casting concrete cross already produce expand, lose expansion water-stop function.
So how to be current technology hardly possible in the seam of diaphragm wall I-steel and second stage concrete installation water expandable waterstop
Point.
