Abstract
The invention discloses a kind of concreting methods, the following steps are included: (1) concreting: concrete uses placement layer by layer, every layer pours thickness control in (30~50) cm, concreting from surrounding toward center cloth, and remains that cushion cap periphery concrete height is slightly higher；(2) concrete vibrating: vibrating head is inserted perpendicularly into when vibrating, it is fast insert it is slow dial, depth of vibrating is more than every layer of exposure (5~10) cm, and while vibrating inserts point uniformly；(3) concrete receives slurry plastering: every layer concrete exposure should carry out second plastering in time and at least after vibrating and receive slurry, to eliminate Plastic settlement cracks and because of plastic shrinkage cracks caused by the quick dehydration in surface；(4) concrete curing: curing agent is sprayed in the exposure for the concrete structure for completing to pour and is laid with curing film and maintenance plate.The invention has the advantages that can effectively enhance placing intensity, it is effectively prevent the generation of distress in concrete, and elastic modulus of concrete can be improved.
Description
Technical field
The present invention relates to concreting technical fields, and in particular to a kind of concreting method.
Background technique
Concreting refers to entering concreting into mould the process until plasticizing, coagulation in civil construction project
It is made predetermined body in the materials to mould such as soil, that there are intensity is inadequate for existing concreting, and there are a large amount of gas for solidification process
Bubble cannot exclude, and because internal-external temperature difference will cause internal and surface, dilatancy cracks concrete everywhere, and shock resistance is poor, pours strong
Spend the problems such as low.Thus need a kind of to enhance placing intensity, concrete cracking can be prevented and the coagulation of impact resistance can be improved
Native casting method.
Summary of the invention
The object of the present invention is to provide the enabled enhancing placing intensity of one kind, concrete cracking can be prevented and coagulation can be improved
The concreting method of native impact resistance.
To achieve the above object, present invention employs following technical solutions: a kind of concreting method, including following step
It is rapid:
(1) concreting: concrete uses placement layer by layer, and every layer pours thickness control in (30~50) cm, concreting
When from surrounding toward center cloth, and remain that concrete height in cushion cap periphery is slightly higher；
(2) concrete vibrating: every layer pour after vibrated using vibrating head, vibrating head is inserted perpendicularly into when vibrating, fast to insert
Slow to dial, depth of vibrating is more than every layer of exposure (5~10) cm, and while vibrating inserts point uniformly；
(3) concrete receives slurry plastering: every layer concrete exposure should carry out second plastering receipts in time and at least after vibrating
Slurry, to eliminate Plastic settlement cracks and because of plastic shrinkage cracks caused by the quick dehydration in surface；
(4) concrete curing: curing agent is sprayed in the exposure for the concrete structure for completing to pour and is laid with curing film and maintenance
Plate realizes that the heat preservation to concrete structure is retained double effects, effectively reduces crack generation.
Further, a kind of concreting method above-mentioned, in which: in concreting process, control concrete
Laitance and plastic cracking, it may be assumed that reduce concrete slump as far as possible under the premise of guaranteeing pumpable, especially pour to last
When (30~50) cm concrete, concrete slump should be lower than 20mm.
Further, a kind of concreting method above-mentioned, in which: in concreting process, control concrete
Pour the intermittent phase, it may be assumed that casting of concrete in mass intermittent phase general control is being less than or equal to 7 days, and longest was no more than 10 days, always
Less than 20 DEG C, the intensity of old concrete is more than the 50% of design strength for concrete maximum temperature and surface temperature difference.
Through the implementation of the above technical solution, it the beneficial effects of the present invention are: can effectively enhance placing intensity, effectively prevent
The generation of distress in concrete, and elastic modulus of concrete can be improved.
Specific embodiment
The present invention is further explained in the light of specific embodiments.
A kind of concreting method, comprising the following steps:
(1) concreting: concrete uses placement layer by layer, and every layer pours thickness control in (30~50) cm, concreting
When from surrounding toward center cloth, and remain that concrete height in cushion cap periphery is slightly higher；
In concreting process, concrete laitance and plastic cracking are controlled, it may be assumed that drop as far as possible under the premise of guaranteeing pumpable
The low concrete slump, when especially pouring to last (30~50) cm concrete, concrete slump should be lower than 20mm；
In concreting process, the concreting intermittent phase is controlled, it may be assumed that casting of concrete in mass intermittent phase general control
It is being less than or equal to 7 days, longest was no more than 10 days, and old concrete maximum temperature and surface temperature difference are less than 20 DEG C, old concrete
Intensity be more than design strength 50%；
(2) concrete vibrating: every layer pour after vibrated using vibrating head, vibrating head is inserted perpendicularly into when vibrating, fast to insert
Slow to dial, depth of vibrating is more than every layer of exposure (5~10) cm, and while vibrating inserts point uniformly；
(3) concrete receives slurry plastering: every layer concrete exposure should carry out second plastering receipts in time and at least after vibrating
Slurry, to eliminate Plastic settlement cracks and because of plastic shrinkage cracks caused by the quick dehydration in surface；
(4) concrete curing: curing agent is sprayed in the exposure for the concrete structure for completing to pour and is laid with curing film and maintenance
Plate realizes that the heat preservation to concrete structure is retained double effects, effectively reduces crack generation.
The invention has the advantages that can effectively enhance placing intensity, it is effectively prevent the generation of distress in concrete, and can be improved mixed
Solidifying soil impact resistance.
