Description
Technical field
The present invention relates to mass concrete construction technical field of temperature control, and in particular to one kind is about large volume coagulation
The temperature controlled technical method of soil.
Background technique
Concrete occupies an important position in modern construction, especially water resources and hydropower construction engineering.It is mixed in large volume
In solidifying geotechnique's journey, temperature control is of great significance.This is mainly due to thermal cracking, shadow usually occur in construction time concrete
Ring globality, stability, barrier properties and the durability for arriving structure；It is also exactly the stress shape in runtime temperature change to structure
State, which has, significantly cannot be neglected influence.
The major measure taken in mass concrete temperature control at present has: fly ash, pre-buried water pipe cooling, bone
Expect pre-cooling, sequence placing, bury block stone, using low-heat cement plus retarder etc..These methods cause while controlling temperature
Other some problems, such as: make that project amount and engineering difficulty increase, project cost rises.
Summary of the invention
The purpose of the present invention is to overcome the above shortcomings and to provide a kind of technologies about mass concrete temperature control
Method, the temperature rise inside dam body can be effectively reduced in it, to be effectively reduced internal-external temperature difference, it is mixed to prevent or reduce large volume
The generation of solidifying soil thermal cracking, while its project amount is smaller, low in cost.
The purpose of the present invention is what is implemented by following scheme:
A kind of technical method about mass concrete temperature control, including concrete, ice cube, terrine, terrine plug, top are solid
Determine ring, tensile materials, lower part fixing belt, buckle, pin.Terrine is placed in inside concrete, and ice cube is housed inside terrine, terrine by
Top fixed ring, tensile materials, lower part fixing belt, buckle and pin are fixed, and prevent terrine from sending out during concrete vibrating
Raw displacement, terrine install ice cube and seal terrine mouth by terrine plug later.
The outer wall of terrine should be smooth in the technical method of mass concrete temperature control, outer wall it is rounded without
It is rectangular.
The material of terrine plug in the technical method of the mass concrete temperature control should be rubber or cork.
Tensile materials in the technical method of the mass concrete temperature control are equally spaced in fixed ring, and
The quantity of tensile materials is no less than three.
It should be first by top Fixing shrink ring when fixing terrine in the technical method of the mass concrete temperature control
On terrine top, then tensile materials are done well as wearing the clothes to terrine, then pin are inserted into lower part concrete, and with card
The tight lower part fixing belt of buckle, buckle to act like waistband the same.
Pin lower portion outer rim has hangnail in the technical method of the mass concrete temperature control, so that pin is firmly
It is inserted in the concrete of lower part.
Size, number, the temperature of thickness and ice cube of terrine in the technical method of the mass concrete temperature control
Depending on should being calculated by specific project situation.
Terrine in the technical method of mass concrete temperature control can used aloned be also arranged as it is certain
Form, such as: long snakelike, quincunx, square matrix type.
Present invention is characterized in that China is ceramic big country, the preparation of terrine is easy, cheap, and ceramics are led
Hot property is poor, and the higher concrete of temperature and the lower ice cube heat transfer process of temperature can be made to slow down.The specific heat capacity of water is very big, energy
Absorb more heat transfer and itself temperature rise is smaller, ice cube is also to be easy to produce.After terrine equipped with ice cube puts concrete into, the later period
Manual maintenance is not needed, it may be said that be to put things right once and for all.A large amount of manpower and material resources are saved.Since the presence of terrine causes dam body
The hole of inside concrete, the presence of these holes can improve the stress state of surrounding, become after ice melting in hole
Water increases internal humidity, is conducive to inner concrete and sufficiently carries out hydration reaction.Since the specific heat capacity of water is very big, when mixed
Water can hinder temperature to increase when solidifying soil increases temperature；Water can hinder temperature to reduce again when concrete reduces temperature,
To be effectively controlled the temperature of inside concrete, the generation and development of distress in concrete are effectively prevented.
Detailed description of the invention
The present invention will be further explained below with reference to the attached drawings.
Fig. 1 is single terrine and concrete combination main view of the invention.
Terrine square matrix-shaped arrangement top view when Fig. 2 is dam body concrete construction in the present invention.
Fig. 3 is the shape graph for being used to fix terrine device in the present invention.
The label declaration of specific embodiment: 1 concrete, 2 ice cubes, 3 terrines, 4 terrine plugs, 5 top fixed rings, 6 tensions
Material, 7 lower part fixing belts, 8 buckles, 9 pins.
Specific embodiment
To keep the technology of the present invention method more clear, With reference to embodiment and referring to attached drawing, to this hair
Bright further description.It should be noted that these descriptions are merely illustrative, and it is not intended to limit the scope of the invention.
It is of the invention main to avoid unnecessarily obscuring in addition, in the following description, descriptions of well-known structures and technologies are omitted
Mentality of designing.
The present invention will be described further by following embodiment, a technique for it is controlled about mass concrete temperature
Method, including 1 concrete, 2 ice cubes, 3 terrines, 4 terrine plugs, 5 top fixed rings, 6 tensile materials, 7 lower part fixing belts, 8 buckle,
9 pins, wherein terrine is placed in inside concrete, ice cube is housed inside terrine, terrine is by top fixed ring, tensile materials, lower part
