Description
Technical field
The present invention relates to a kind of defects handling methods of construction quality, and in particular to a kind of culvert of reinforced concrete subsiding crack
Seep water Treatment Methods.
Background technique
Highway, railway often build the safety that culvert meets roadbed when across coombe and exclusion roadbed inner side edge ditch water flow
With it is continuous.Reinforced concrete cover plate is contained because lower and of less demanding to foundation stress to the depth of fill requirement of hole top, and construction is just
Benefit is widely used in engineering.
To prevent differential settlement, culvert generally segmented construction sets subsiding crack between segment, fills out in subsiding crack with pitch
Loose hemp fiber or other impermeable materials.In terms of engineering practice, because construction technology influences, construction joint waterproof effect is often not satisfactory, nothing
Method prevents water flow in culvert and penetrates into roadbed, causes filled-up ground to generate differential settlement, or even influence subgrade stability；Or it is current
Infiltration everywhere leads to current difficulty to culvert after the rain, and social influence is severe.But culvert and culvert roadbed have filled completion, nothing
Method carries out water-proofing treatment in culvert lateral surface to determine the stabilization of roadbed and reduce social influence by original design.
Summary of the invention
The technical problem to be solved by the present invention is providing the infiltration restorative procedure of subsiding crack in the new culvert of one kind, it is not necessarily to
Banketing on the outside of culvert roadbed is excavated, does not destroy on the basis of the main force structure of culvert, slot treatment is carried out in culvert
Mode carry out reparation punishment.
The technical scheme is that
A kind of culvert of reinforced concrete subsiding crack infiltration restorative procedure comprising the steps of:
The first, it is cut with cutting machine in former culvert subsiding crack two sides, then uses electric impact drill tick slot, then be aided with artificial refine into ditch
Slot；
The second, jewel hole, installation Grouting Pipe and slip casting at former culvert subsiding crack with electric drill；
Third, cleaning gap and groove, install aqueduct at former culvert subsiding crack, install drainage hole every certain spacing；
4th, filled layer is carried out in the good groove of artificial refine；
5th, with construction waterproof layer after the concrete surface layer carbide of mechanical removal subsiding crack two sides.
The size of groove is width 4-6cm, deep 6-10cm；Filled layer in groove is clogged using Bituminous hemp fiber, is used after filling
Fast hard waterproof mortar smears the surface of tooled joint.
The interval 20-30cm of Grouting Pipe, hole depth 8-12cm, aperture 10-20mm；The perfusion of grouting high-pressure injection pump is water-soluble
Completion is once perfused from culvert bottom toward culvert top when perfusion in the mixed liquor of property polyurethane leak-stopping agent and acetone, and grouting pressure reaches
Stop slip casting after 0.5MPa, after injection slurry solidification in 1 to 2 days, removal slip casting nail blocks injected hole with leak stopping king.
Aqueduct uses the half of pvc pipe of diameter 2cm；Drainage hole uses the pvc pipe of diameter 2cm, and installation number is according to going out
Water selection.
The construction of waterproof layer are as follows: after epoxy resin pastes triplex glass silk cloth, applied again after one bed boundary agent of external coating
It brushes twice of BPS high strength elastic waterproof material and carries out water-proofing treatment；Surface requirements are smooth, closely knit, bubble-free, without infiltration.
A kind of culvert of reinforced concrete subsiding crack reparation structure, including subsiding crack, the cutting of subsiding crack two sides accomplish groove, sink
Drilling installation Grouting Pipe and slip casting at seam are dropped, and interior subsiding crack is laid with aqueduct along groove, opens up drainage hole simultaneously on aqueduct
Drainpipe is installed, clogs filled layer in groove, flute surfaces have waterproof layer.
Filled layer is Bituminous hemp fiber, triplex glass cloth surface brushing interfacial agents that waterproof layer is pasted by epoxy resin and
BPS high intensity coating forms.
Drainage hole is located at the bottom of subsiding crack.
Aqueduct is half of pvc pipe, and open section is towards subsiding crack.
Beneficial effects of the present invention:
The roadbed filled is not destroyed, does not destroy the main body force structure of culvert；Water blockoff is carried out by 1 slip casting of Grouting Pipe；It is logical
It crosses and buries 2 ejectment of aqueduct in former culvert subsiding crack；Filled layer 3 and construction waterproof layer 4 are clogged after expanding seam by subsiding crack, is had
Effect prevents water from exosmosing.
The present invention has effectively handled culvert subsiding crack seepage problem, and anti-seepage effect is obvious, easy to operate, economic and practical.

Specific embodiment
The embodiment of the present invention:
The first, it is cut with cutting machine in former culvert subsiding crack two sides, then uses electric impact drill tick slot, then be aided with artificial refine into ditch
Slot 6；The size of groove 6 is width 5cm, deep 8cm.
The second, jewel hole, installation Grouting Pipe 1 and slip casting at former culvert subsiding crack with electric drill；The interval 25cm of Grouting Pipe 1,
Hole depth is 10cm, aperture 15mm；The mixed liquor of water soluble polyurethane leak-stopping agent and acetone is perfused in grouting high-pressure injection pump, fills
Completion is once perfused from culvert bottom toward culvert top when note, grouting pressure stops slip casting, injection slurry solidification in 1 ~ 2 day after reaching 0.5MPa
Afterwards, removal slip casting nail blocks injected hole with leak stopping king.
Third, cleaning gap and groove 6, aqueduct 2 is installed at former culvert subsiding crack, sets draining every certain spacing
Hole 5；Aqueduct 2 uses the half of pvc pipe of diameter 2cm, and section is open towards subsiding crack；Install diameter 2cm's at drainage hole 5
Pvc pipe, installation number are selected according to water yield, general only to install at one in the bottom of subsiding crack.
4th, filled layer 3 is carried out in the good groove 6 of artificial refine；Filled layer 3 in groove 6 is filled out using Bituminous hemp fiber
Plug smears the surface of tooled joint with fast hard waterproof mortar after filling.
5th, with construction waterproof layer 4 after the concrete surface layer carbide of mechanical removal subsiding crack two sides.The construction of waterproof layer 4
After pasting triplex glass silk cloth for epoxy resin, it is anti-to brush twice of BPS high strength elastic again after one bed boundary agent of external coating
Water material carries out water-proofing treatment；It is required that surfacing, closely knit, bubble-free, without infiltration.
The cargo handling operation of this method is combined using anti-unimpeded, is closed by grouting for water blocking, pipe laying ejectment, construction waterproof layer
Mode carry out infiltration punishment.
