Abstract
The invention discloses a kind of basement bottom board crack restorative procedures, comprising the following steps: a. cleaning；B. it drills；C. mouth is buried；D. slip casting；E. mouth is torn open.The invention has the characteristics that method is simple, easily implement, repairing effect is good, guarantees construction quality.
Description
Technical field
The present invention relates to engineering fields, and in particular to a kind of basement bottom board crack restorative procedure.
Background technique
With the fast development of China's economy, the continuous quickening of urbanization process, Large Underground parking lot, market, people's air defense
Engineering is more and more, and for the basement of large area, soleplate crack will affect whole building quality.
Summary of the invention
Problem that the purpose of the present invention is to overcome the above shortcomings provides a kind of basement bottom board crack restorative procedure.
Present invention technical solution used for the above purpose is: basement bottom board crack restorative procedure, including with
Lower step: a. cleaning: detailed inspection, analysis leakage scenarios determine slip casting hole site and spacing, clean out the area for needing to construct
Domain cuts concrete screed-coat and substrate surface precipitate, it is ensured that surface is clean, soaks；
B. it drills: being drilled using boring bar tool along crack two sides, drilling has to pass through crack, but must not punch structure；
C. it buries mouth: grouting nozzle being installed in the hole being drilled, and is tightened, make around grouting nozzle the tight between drilling, it is water-tight；
D. slip casting: using high-pressure grout injector slip casting, after adjacent holes start pulp, holding pressure 3 ~ stop this hole note after five minutes
Slurry changes the adjacent injected hole of note；
E. tear mouth open: slip casting finishes, and confirmation can be removed after not leaking or knock out exposed grouting nozzle, then cleans out cured
The injection slurry that spill and leakage goes out.
Drilling and fracture interval are 20cm-30cm, spacing of wells 10cm-20cm in step b.
When step d, facade grouting sequence is from bottom to top that since one end, single hole is carried out continuously one by one for plane slip casting.
The invention has the characteristics that method is simple, easily implement, repairing effect is good, guarantees construction quality.
Specific embodiment
The present invention is a kind of basement bottom board crack restorative procedure, comprising the following steps:
A. clear up: detailed inspection, analysis leakage scenarios determine slip casting hole site and spacing, clean out the region for needing to construct,
Cut concrete screed-coat and substrate surface precipitate, it is ensured that surface is clean, soaks；
B. it drilling: being drilled using boring bar tool along crack two sides, drilling has to pass through crack, but must not punch structure,
Drilling is 20cm-30cm, spacing of wells 10cm-20cm with fracture interval；
C. bury mouth: grouting nozzle being installed in the hole being drilled, and is tightened with Special inner hexagon spanner, make around grouting nozzle with drilling
Between tight, it is water-tight；
D. slip casting: using high-pressure grout injector slip casting, and facade grouting sequence is from bottom to top that plane slip casting is since one end, single hole
It is carried out continuously one by one, after adjacent holes start pulp, holding pressure 3 ~ stop this hole slip casting after five minutes changes the adjacent injected hole of note；
E. tear mouth open: slip casting finishes, and confirmation can be removed after not leaking or knock out exposed grouting nozzle, then cleans out cured
The injection slurry that spill and leakage goes out.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art within the technical scope of the present disclosure, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
