Description
Technical field
The repairing that the utility model the relates to a kind of exterior wall split bolt hole pick-up unit that is filled with water.
Background technology
Along with the development of commercial residential buildings industry, the significant rise of commercial house price, the small proprietor is also more and more higher to the requirement of residential building.Water leakage through exterior wall is one of main common quality defect of traditional construction technology, the exterior wall of reinforced concrete shear wall wherein, its split bolt hole have quantity many, run through interior exterior wall, be difficult for repairing, easily cause the characteristics such as seepage, what become water leakage through exterior wall easily sends out the position.
The utility model content
The problems referred to above that exist for solving prior art, the repairing that the purpose of this utility model the provides a kind of exterior wall split bolt hole pick-up unit that is filled with water, it can solve exterior wall split bolt leakage problem, percolating water just can be solved before hidden examination effectively, avoid exterior wall leakage, construction quality further is guaranteed, and the later period maintenance that reduces construction quality is taken, and has good economic and social benefit.
For solving above purpose, the utility model can be achieved by the following technical programs:
The repairing of a kind of exterior wall split bolt hole of the present utility model pick-up unit that is filled with water, comprise half a bowl-shape plastic tube that is fixed on the steel concrete outer wall outside with sand-cement slurry, partly bowl-shape plastic tube and exterior wall outside forms " bird's nest formula " water container, after strength of cement mortar reaches, in this half bowl-shape plastic tube, be filled with water and carry out the repairing leak detection in exterior wall split bolt hole.
As further feature of the present utility model, the diameter of going to the bottom of described half bowl-shape plastic tube is 30mm, and high 90mm is similar to half bowl.
As further feature of the present utility model, described half bowl-shape plastic tube adopts sand-cement slurry to be fixed between two parties exterior wall outside split bolt hole, and half bowl-shape plastic tube end opening is lower than the split bolt hole, the split bolt hole 70mm that is higher than suitable for reading.
As further feature of the present utility model, the height of water level that is filled with water is higher than split bolt hole 40～70mm.This moment is according to formula hydrostatic force P=ρ * g * h
(ρ is water-mass density 1 * 10
3Kg/m
3, g is acceleration of gravity 9.8N/kg, h is height of water level)
Hydrostatic force P=ρ * g * h
＝1×10
3Kg/m
3×9.8N/kg×(40～70mm)
＝9.8×10
3N/m
3×(40～70mm)
＝392～686N/m
2
＝392～686Pa
Namely being filled with water, hydrostatic force should be 392～686Pa when detecting,
As further feature of the present utility model, it is optimum height that the height of water level that is filled with water is higher than split bolt hole 60mm, and this moment, hydrostatic force was 588Pa.
As further feature of the present utility model, when the described height of water level that is filled with water was higher than split bolt hole 60mm, the time of leak detection was 24 hours.Non-leakage in 24 hours, then exterior wall split bolt hole repairing quality is qualified.In 24 hours, seepage is arranged, then need again to repair, again detect after the repairing.
The utility model through the detection that effectively is filled with water, is avoided exterior wall leakage after can guaranteeing that steel concrete outer wall split bolt cavity is repaired, and finally realizes exterior wall split bolt hole ne-leakage, improves engineering construction quality, reduces later stage quality maintenance.

Embodiment
Below in conjunction with specific embodiment, further set forth embodiment of the present utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Shown in Fig. 1-6, after steel concrete outer wall 1 form removable of the present utility model, through-wall bolt 2 in the taking-up is removed through-wall bolt plastic casing 3 with drill bit, and ash, slag cleaning in the hole totally should be sprinkled water moistening.Mixed 1: 2.5 sand-cement slurry 4, minute three repairings, eye all fills up, and the repairing time was separated by 24 hours at every turn.First is repaired within the walls side 1/3 degree of depth, and second is mended the wall outside 2/3 degree of depth, and wall surface 5-10mm is repaired in the 3rd road.Mix micro-expanding agent in first, the second mending mortar, mix water-proofing agent in the 3rd road mending mortar.Should carry out water seasoning after the repairing.Prepare what a half bowl-shape plastic tube 5, base diameter prolongs 30mm, and high 90mm is similar to half bowl.With sand-cement slurry 7, one and half bowl-shape plastic tubes 5 are fixed on the exterior wall outside, and half bowl-shape plastic tube end opening is lower than the split bolt hole, and three are all adopted sand-cement slurry 7 secure dense, end opening is fixed in split bolt hole 8 end opening 20mm, and half bowl-shape plastic tube 5 exceeds split bolt hole 8 70mm suitable for reading.Make half bowl-shape plastic tube 5 and exterior wall outside form " bird's nest formula " water container.After sand-cement slurry 7 reaches intensity, can add water 6 in " bird's nest formula " water container the inside, when water level is higher than split bolt hole 40～70mm, namely reaches and detect needed hydrostatic force, when this moment, hydrostatic force was 392～686Pa.
According to formula hydrostatic force P=ρ * g * h
(ρ is water-mass density 1 * 10
3Kg/m
3, g is acceleration of gravity 9.8N/kg, h is height of water level)
Hydrostatic force P=ρ * g * h
＝1×10
3Kg/m
3×9.8N/kg×(40～70mm)
＝9.8×10
3N/m
3×(40～70mm)
＝392～686N/m
2
＝392～686Pa
That is, detect the water surface and surpass exterior wall split bolt hole 8 40mm suitable for reading, produce the 392Pa hydrostatic force, when detecting the water surface above exterior wall split bolt hole 70mm, produce the 686Pa hydrostatic force.
Use actual conditions according to exterior wall, because exterior wall can not produce ponding, its percolating water main source is the rainwater along metope, and rainwater penetrates into indoor along the uncompacted slit of repairing, and water pressure is very little.According to simulation test repeatedly, the factors such as synthesis repairing quality condition, exterior wall thickness, the horizontal leak factor of distress in concrete, when the water surface exceeded at the bottom of the split bolt hole 40～70mm, the hydrostatic force 392～686Pa that produces can carry out timely and effectively percolating water and detect.When the water surface exceeds at the bottom of the split bolt hole 60mm, be the optimum detection height of water level, this moment, hydrostatic force was 588Pa as can be known according to above-mentioned formula.Under this hydrostatic force, just can detect the seepage situation in split bolt hole 8 in 24 hours, testing result can reflect exterior wall split bolt hole repair quality fully, if seepage did not occur in 24 hours, can assert that then the split bolt hole repair is up-to-standard.In 24 hours, seepage is arranged, then need again to repair, again detect after the repairing.Because exterior wall split bolt hole number is many, 24 hours detection time, can guarantee the work efficiency that detects.
