Description
Technical field
The present invention relates to a kind of slip casting structure, a kind of basement bottom board infiltration crack slip casting structure and slip casting thereof
Engineering method.
Background technology
Along with the fast development of China's economy, the continuous quickening of urbanization process, construction scale of projects increases day by day, how really
While protecting construction engineering quality, building can be made again permanent, safe use to go down, gradually become governments at all levels and society
The focus of meeting all circles.In numerous engineering constructions, concrete uses face ratio wide, and the crack problem of concrete is simultaneously
Through becoming problem relatively conventional in construction quality；Distress in concrete divides according to local environment can be divided into dry and cracked seam and infiltration substantially
Two kinds of crack.
Not having the crack of open fire in dry and cracked seam i.e. crack, this fracture unit mode ratio is more conventional, and it is typically with chemistry note
The mode of slurry carries out crack treatment.Infiltration crack, owing to there being the existence of water, can not effectively process, particularly basement all the time
The infiltration crack treatment of base plate is always difficult point.
Summary of the invention
Present invention aims to existing can not the effective problem such as process to basement bottom board infiltration crack, it is provided that a kind of ground
Lower room base plate infiltration crack slip casting structure and slip casting construction method thereof.
For achieving the above object, used technical solution is the present invention: a kind of basement bottom board infiltration crack slip casting structure,
Including basement bottom board, on described basement bottom board, through-thickness is distributed infiltration crack, angularly disposed on basement bottom board
Having pod apertures, described pod apertures bottom to intersect with infiltration crack, described infiltration fracture faces is provided with fluid sealant, and infiltration is split
Sew on and be alongst embedded with one or more slurry outlet nozzle.
Described pod apertures and basement bottom board angle of intersection are 45 degree.
Described pod apertures bottom is intersected in the middle part of infiltration crack.
Spacing between described adjacent slurry outlet nozzle is 30cm.
The slip casting construction method of a kind of basement bottom board infiltration crack slip casting structure, comprises the following steps:
Step one, first along being that pod apertures is beaten in 45 degree of directions with basement bottom board angle of intersection, makes this pod apertures and seeps water in crack
Portion crosses；Step 2, then cleaning infiltration crack, bury slurry outlet nozzle underground on infiltration crack the most at a certain distance,
With fluid sealant, infiltration fracture faces is all sealed again；Step 3, after the sealing glue solidifying of water crack seam surface for seep, along water conservancy diversion
Hole starts from infiltration one end, crack toward other end slip casing by pressure, and slurry outlet nozzle is to emit clear water to be followed by emitting underflow, if only burying underground at the beginning
One slurry outlet nozzle, then blocking after this slurry outlet nozzle emerges underflow, if burying multiple slurry outlet nozzle underground, then treating that first slurry outlet nozzle is emerged clearly
During water, close other slurry outlet nozzles, then emerge first slurry outlet nozzle of underflow rear enclosed at first slurry outlet nozzle, and successively to remainder
Slurry outlet nozzle carry out aforesaid operations, slip casing by pressure amount herein by formula below control: average thickness x crack, penetration of fracture x crack is long
Degree.
When the fracture length that seeps water is more than 2m, 1m can be spaced and offer pod apertures, and repeat the above steps one to three again.
Compared with prior art, the invention has the beneficial effects as follows:
By arranging pod apertures water conservancy diversion in the present invention, create water-less environment for infiltration crack slip casting, then use the side of slip casing by pressure
Infiltration crack is processed by formula, can be widely applied in basement bottom board crack such that it is able to effectively process the most a large amount of existence
Basement bottom board infiltration crack in the difficult problem of existence of water.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Fig. 2 is slip casing by pressure floor map in the present invention.
In figure, basement bottom board 1, crack 2 of seeping water, pod apertures 3, slurry outlet nozzle 4.
Detailed description of the invention
Illustrate that the present invention is described in further detail with detailed description of the invention below in conjunction with accompanying drawing.
Seeing Fig. 1 to Fig. 2, a kind of basement bottom board infiltration crack slip casting structure, including basement bottom board 1；At the bottom of described basement
On plate 1, through-thickness is distributed infiltration crack 2.Angularly disposed on basement bottom board 1 have pod apertures 3, described pod apertures 3 bottom
Intersect with infiltration crack 2.Described infiltration crack 2 surface configuration has fluid sealant, infiltration to be alongst embedded with one on crack 2
Individual or multiple slurry outlet nozzles 4.
Seeing Fig. 1 to Fig. 2, described pod apertures 3 is 45 degree with basement bottom board 1 angle of intersection.
Seeing Fig. 1, described pod apertures 3 bottom is intersected in the middle part of infiltration crack 2.Infiltration crack 2 is that a kind of two ends are relatively thin, middle
The crack of drum, pod apertures 3 is just heaved position in the middle part of crack 2 in 45 degree angles intersect with being seeped water under normal circumstances.
Seeing Fig. 2, the spacing between described adjacent slurry outlet nozzle 4 is 30cm.
See Fig. 1 to Fig. 2, the slip casting construction method of a kind of basement bottom board infiltration crack slip casting structure, by arranging pod apertures 3 water conservancy diversion,
Create water-less environment for infiltration crack 2 slip casting, then use the mode of slip casing by pressure that infiltration crack 2 is processed, specifically include
Following steps:
Step one, first along being that pod apertures 3 is beaten in 45 degree of directions with basement bottom board 1 angle of intersection, makes this pod apertures 3 and infiltration crack
Cross in the middle part of in the of 2.
Step 2, then cleaning infiltration crack 2, bury slurry outlet nozzle 4 underground on infiltration crack 2 the most at a certain distance, this
Individual spacing is typically to be about 30cm；With fluid sealant, surface, infiltration crack 2 is all sealed again.
Step 3, after the sealing glue solidifying on 2 surfaces is stitched in water crack for seep, starts from infiltration one end, crack 2 toward the other end along pod apertures 3
Slip casing by pressure, slurry outlet nozzle 4 is to emit clear water to be followed by emitting underflow at the beginning, if only burying a slurry outlet nozzle 4 underground, then treats this slurry outlet nozzle 4
Block after underflow of emerging.If burying multiple slurry outlet nozzle 4 underground, then, when first slurry outlet nozzle 4 emerges clear water, close other slurry outlet nozzles 4,
Then emerge first slurry outlet nozzle 4 of underflow rear enclosed at first slurry outlet nozzle 4, and successively remaining slurry outlet nozzle 4 is carried out above-mentioned behaviour
Make.Slip casing by pressure amount herein is controlled by formula below: penetration of fracture x crack average thickness x fracture length.
Concrete, when crack 2 length that seeps water is more than 2m, 1m can be spaced and offer pod apertures 3, and repeat the above steps one to three again.
See Fig. 1 to Fig. 2, the composite can be widely applied in basement bottom board 1 crack such that it is able to effectively process and deposit in a large number at present
Basement bottom board 1 infiltration crack 2 in there is the difficult problem of water, it is ensured that construction quality.
Above content is to combine concrete preferred implementation further description made for the present invention, it is impossible to assert the present invention
Be embodied as be confined to these explanations.For general technical staff of the technical field of the invention, without departing from this
On the premise of inventive concept, it is also possible to make some simple deduction or replace, said structure all should be considered as belonging to the guarantor of the present invention
Protect scope.
