Description
Technical field
The present invention relates to leakage of buildings control, especially basement deformation joint and adopt the packing seepage prevention and treatment method, belong to Building technology.
Background technology
Because the influence of external condition and the needs of construction exist shrinkage joint, settlement joint and constuction joint in underground construction, these seams are weak links of percolation-proof.Because the lifting of temperature, the heavy of ground moves, and the rocking of high-rise building top, earthquake etc. all might cause the dilatation of building.The south of the River one band, rainfall is plump, and groundwater table usually is higher than the baseplane of basement.The seepage of underground construction deformation joint is particularly outstanding a kind of of multiple seepage phenomenon, administers also more thorny.The problem that housing basement leaks not only endangers stable formation of building structural safety, also influences its function of use.High speed development along with global building trade, the building scholars compare the dilatation problem of in the past paying close attention to more in the building structure, in recent years, the insider is more to article, the scheme of underground engineering project deformation seam treating seepage, the Material Used kind is also many, opinions vary, but regulation effect is unsatisfactory.That cures lacks, and controls bad manyly, once lacking of radical cure, controls leak repeatly many repeatly, has become a great problem for the treatment of seepage.
Show that after deliberation the basement deformation joint is along with the sedimentation of the distortion of ground, building and variation of temperature and constantly changing.It is bad thereby waterstop joint lap-joint bonding to occur, is the state that comes off or partly come off, and can not form the water proof ring of sealing; Cause the waterstop burial place inaccurate, often squeezed partially by concrete, waterstop twists in concrete, crimping, even is extruded outside the wall.Therefore, waterstop does not have sealing and adapts to the effect of being out of shape.Through investigation statistics, the more settlement joint place that adopts steel framework rubber fastening band waterproof that concentrates on of underground building structural leakage.
As everyone knows, the seepage main cause of deformation joint has three kinds, and the one, water oozes out along the periphery of waterstop; The 2nd, water oozes out along the pore fluid of concrete of waterstop periphery; The 3rd, waterstop is punctured by hard thing, or water to end belt lacing regioselective improper.Because of the foundation settlement inequality, building produces distortion, and waterstop is overstepped the extreme limit by drawing crack, causes percolating water.The problem of the two outstanding reflection is a waterstop periphery concrete vibration leakiness, shrinkage factor is big, even also leave the space, cause the concrete parcel of the waterstop wing not tight, particularly below the waterstop of base plate position and corner, become the passage of percolating water, press water can be along the both wings of waterstop and the gap seepage between the concrete.How can waterstop periphery concrete vibrating is closely knit, this is neither an easy thing, and the topic that neither the present invention will inquire into is only at the improvement with regard to leakage problems that this phenomenon is brought.
The unit in charge of construction that has adopts water glass and cement to tamp when handling percolating water, and what have fills and leads up compacting with the leak stopping spirit, also useful polymer cement mortar or the like.These simple and easy processing methods all belong to rigidity, and tensile strength is low, and the needs of incompatibility malformation soon, infiltration still occurs.Take a broad view of many control expert Lou about underground construction deformation joint improvement method be nothing but chemical grouting, sealing compound shutoff, several water-repellent paint, polymer class waterproofing mortars of filming of waterproofing materials, brushing of pasting which floor high-elongation several processing methods such as wipe one's face all over high-elongations, its theory is a multi-way prevention, but actual work again what are arranged? all be annotated the slurry all right, leak the coming year again.
Summary of the invention
The present invention is directed to the problems referred to above, in order to solve a seepage difficult problem, propose a kind of basement deformation joint seepage improvement method, the promptly soft intestines method of moulding.
Technical scheme of the present invention is: A. is moulded and is moulded the soft sticking material of state near stream by soft, pours into sealing bag and makes the soft intestines packing of moulding; B. coated waterproof adhesive on the wall of deformation joint and waterstop burial place; C. packing is filled up deformation joint, cover elastic layering, press pad, then fixed by nut.
Described this soft sticking material is non-solid but also on-liquid not only, belongs to Binghambody.By index of plasticity I
P〉=10, coefficient of permeability K＜1 * 10
7The clay 20～40% of cm/s, water 30～60%, oil 0～30%, additive 0～2% are formed.
Described clay has admaic earth, yellow clay and silt clay, and sieving, it is stand-by to remove impurity.Water can adopt lake water, well water or tap water.Oil can adopt the oil of industrial waste oil and municipal sewage system abandoned oil or treated regeneration.The liquidity index of clay sealing material is got 0.85＜I
LBetween≤1, make that soft sticking material is long-term to be kept soft and mould and mould state near stream, to adapt to the variation of deformation joint.
Described additive is one or more in surfactant, tackifier and the anticorrisive agent, as neopelex, sodium carboxymethylcellulose CMC and for example, can regulate the physical parameter of these clay materials, as keep the stability of clay sealing material, and reduce fluid loss, adjust viscosity, increase thixotropy, prevent to go mouldy and emanate.
The described soft intestines packing of moulding adopts sealing bag to wrap up soft sticking material to form, and sealing bag generally is 2～5 times of deformation joint with thin-film materials such as fluid-tight plastics, rubber and nylon, the diameter after the sealing bag air blowing.After irritating soft sticking material, seal bag seals.The fill rate of soft sticking material in sealing bag is 60%～75%.Because the sealing and the air impermeability of sealing bag make soft sticking material not run off, not dry up, and can keep soft-plastic state for a long time.When deformation joint was out of shape, the inwall of sealing bag and deformation joint was bonding, and the soft sticking material in the sealing bag is out of shape still whole abrim slit thereupon.
Described waterproof adhesive generally adopts commercially available building adhesive, as epoxy resin adhesive, pitch adhesive, rubber adhesive, also can oneself prepare.Must be noted that waterproof adhesive and sealing bag compatibility during apolegamy.The waterproof adhesive is evenly brushed on concrete surface, packing and the rubber press strip on the inwall of deformation joint and both sides.When packing and packing overlap joint, also need brushing waterproof adhesive.After packing embedding distortion seam and press strip cover, just can make the inwall of sealing bag and deformation joint bonding firmly, connect reliably, seamless zero-clearance is to stop the seepage of water.
Described press strip adopts elastomeric material, and rubber tile commonly used is made, and covers on the openning of deformation joint, and reserves distortion allowance.When deformation joint became big, press strip was stretched, and the soft sticking material in the packing is pressed into deformation joint.When deformation joint diminished, press strip arched upward, and the soft sticking material in the packing is forced out deformation joint, accumulates on the openning of deformation joint.Another effect of press strip is a pressure of resisting percolating water.
The present invention has following advantage:
Because the present invention is by coated waterproof adhesive on the wall of deformation joint and waterstop burial place, it is firm bonding to make the wall of packing and deformation joint have, the bag film that wraps up soft sticking material is close to the wall of deformation joint, overcome the deformation joint wall and be uneven and tiny hole seam, stoped water to ooze out effectively from the wall of deformation joint.
Because the present invention makes the flexible soft intestines packing of moulding and is embedded in the deformation joint adopting the diaphragm seal bag to wrap up soft sticking material, has both guaranteed that soft sticking material does not run off, and can make non-sclerous the never degenerating of soft sticking material again.Thereby can be out of shape along with the variation of deformation joint, stop the seepage of basement deformation joint.It is all right to have solved slip casting, leaks problem the coming year again.
Because the present invention after packing is embedded in deformation joint, presses the rubber-like press strip.Both guaranteed the breathing of packing in deformation joint, and can effectively overcome the pressure of underground water again packing.Packing is not abandoned in deformation joint for a long time.
Because the present invention adopts clay, water, oil, additive to form, keep the soft interior pH value of intestines packing of moulding between 7.5～9.0.Can regulate these soft sticking materials and reduce fluid loss, adjust viscosity, increase thixotropy, segregation prevents to go mouldy.Stable for extended periods of time soft moulded and moulds state near stream, thereby prolonged application life, and regulation effect is remarkable.
Because the present invention draws materials easily, and is cheap, easy construction install simply, and speed is fast, work efficiency height, remarkable in economical benefits.Compare with traditional method and technology, work efficiency improves 1～3 times, and the duration shortens more than 60%, and cost reduces about 50%, and reliability and safety all are greatly improved.Characteristics with mobility height, applied range.
