Abstract
The present invention relates to a construction technology of preventing and controlling seepage water in a building; a plurality of water proof building materials are selected effectively; a proportion is adjusted, and the construction technology is changed so that the a plurality of water proof building materials have performance of water prevention and water stop; the present invention provides a feasible construction method so that the parts of seepage water are adjusted. The present invention is suitable for the leakage of points, lines and surfaces of buildings, and is especially suitable for deformation joints (settlement joints and expansion joints) and construction joints of underground buildings, civil defense engineering, railway subways, railway tunnels and hydraulic engineering, and parts of underground structures passing through various pipelines.
Description
The invention belongs to the repair method of existing building thing, be specially adapted to underground structure deformation joint seepage water regulation.
The underground building is given when design and construction and is stayed some slits, and owing to concrete structure is subjected to some factor affecting generation sedimentation, the flexible crack that produces, the infiltration phenomenon usually occurs.It is stifled that prior art generally adopts cement to mix accelerating admixture, embeds the method leak stopping of ointment joint seal again, its weak effect.Reason is big, the easily generation be full of cracks of cement shrinkage of mixing accelerating admixture, and the multilayer pitch class that embeds owing to contain solvent, along with the volatilization hardening gradually of solvent, has reduced strain capacity, and continues the generation infiltration.Disclose a kind of loss circulation material and method in CN-GK87100498A, it utilizes ferric trichloride and frerrous chloride, with the ferric hydroxide colloid that is insoluble in water that forms behind the cement aquation.It is a kind of colloidal suspension particle, is filled in cement mortar or pore fluid of concrete, has improved the density of structure, has strengthened anti-permeability performance.In concrete structure or plastering waterproof layer, mix the iron chloride waterproof agent, its objective is and improve the structurally waterproof performance, but, spread or the stifled cement mortar that goes up, easily washed away loss, do not reach the purpose of water blockoff by infiltration at the percolating water position.
The objective of the invention is to propose a kind of novel preventing and controlling seepage method, it has special job practices and special third and coagulates the airtight slip casting zone that cement grout and tar polyurethane coating form, and can prevent seepage effectively, and job practices is simple.
Invention is achieved in that a kind of preventing and controlling seepage in buildings job practices; coagulate cement grout by third; airtight and watertight padding; tar polyurethane coating; the plugging watertight layer that cement mortar protective course is formed; wherein third coagulates cement grout and forms an airtight slip casting zone by the Grouting Pipe perfusion; Grouting Pipe is made up of the foaming flexible pipe; Grouting Pipe is imbedded in the groove; interval according to 0.3～1.0 meter is buried underground; dark 10～12 centimetres of groove; its airtight and watertight padding that is embedded in is expanded rubber or polyvinyl chloride band shape adhesive tape; third coagulates cement grout by first; two kinds of liquid of second are according to the constant weight percentage mix; first liquid contains acrylamide 7～16%; methylene-bisacrylamide 0.4-0.8%; triethanolamine 0.5-1%; water accounts for 24-35%, cement 5～10%, and second liquid contains Ammonium Persulfate 98.5 0.5-1%; water accounts for 40-45%; cement accounts for 5-10%, and tar polyurethane is by third; two kinds of liquid of fourth are formed, and third liquid contains polyethers resin 18～30%; toluene di-isocyanate(TDI) 2-10%; dibutyl phthalate accounts for 0.5-3%, and fourth liquid contains coal tar 60～75%, curing compound 1.5-4.5%.
Fig. 1: grouting remediation crack construction process schematic representation
Fig. 2: vertical fracture regulation schematic diagram
Now further narrate by reference to the accompanying drawings the present invention
Referring to Fig. 1: 1 place is with in the infiltration in the needs regulation, puts into Grouting Pipe 2, according to the physical dimension of groove, embedding sealing material 3 will from up to down carry out, and is coated with then two-layer tar polyurethane coating, thick 0.7～the 1.0mm of subbing, total paint thickness are 1.7～2mm.
Referring to Fig. 2: the vertical or annulus 1 of structure, to inject third in the Grouting Pipe 2 and coagulate cement mortar, expanded rubber or polyvinyl chloride band shape adhesive tape, tar polyurethane coating 4, cement mortar protective course 5 are adopted in airtight and watertight padding 3.
This job practices can adopt corresponding structure pattern and regulation method according to different deformation behaviours and water percolating capacity, adopts third to coagulate the multi-level waterproofing materialss of formation such as cement mortar, tar polyurethane.Has easy construction, simple to operate, strong, characteristics such as good water-proof effect to distortion compliance.
Now further narrate construction sequence of the present invention in conjunction with the embodiments and use material:
1, with dark 10-12 centimetre of percolating water position groove, clear up smooth;
2, utilize the quick hardening cement supple-management of will foaming to go in the groove, every about one meter, bury two of Grouting Pipe (annotate, row with) underground, form a slip casting zone, bury underground in proper order and carry out from top to bottom;
3, annotate third and coagulate that cement grout is top-down to carry out, after slurries solidify, be folded down Grouting Pipe, fill and lead up with the quick hardening cement sealing of hole;
4, press physical dimension embedding expanded rubber or polyvinyl chloride adhesive tape in the groove;
5, be coated with the secondary tar polyurethane in its surface, gross thickness is the 1.7-2.0 millimeter, and width is greater than groove width 12-15 centimetre;
6, behind second time coating tar polyurethane, sprinkle dry sand, after 24 hours, smear cement mortar protective course;
Cement grout composition such as table 1 are coagulated in third of employing.
