Comprises two sections of symmetrically arranged spray water pipes (1); two sections of symmetrically arranged spray water pipes are fixed on a tension steel wire rope (2) through a fixed steel wire (3), and two ends of the tension steel wire rope (2) are fixed on dam shoulders of two banks; one end of the spray water pipe is provided with a water inlet hole (6), and the other end of the spray water pipe is sealed by a plug (5); a group of uniformly distributed water spraying holes (4) are arranged along the length direction of the spray water pipe. The utility model discloses can make all be in the microclimate environment of large tracts of land spraying in the air of storehouse face top certain limit, the water particle in the air is distributed to the mist cooling system, will absorb the heat in a large amount of surrounding environment at the in-process of vaporization, thereby evaporative cooling reduces ambient temperature, and the air cooling effect is showing around the storehouse face.
Description
Technical field
A kind of Construction of Rolled Concrete Dam storehouse face miniclimate heat sink is the utility model is related to, belongs to Hydraulic and Hydro-Power Engineering
Technical field.
Background technology
The situation of RCCD construction during hot season is frequently encountered in Construction for Hydroelectric Project, it is mixed due to rolling
Solidifying earth dam belongs to mass concrete, and it has a temperature control requirement, and during grinding concrete construction its environment temperature control
It is wherein part and parcel, existing temperature controlled way:First, using the method covered, this method can avoid the sun to hiding
The straight solarization of the following air of cover material, the reduction for contributing to grinding coagulation soil environment temperature interior in short-term, but air has mobility, necessarily
Temperature control effect is very poor after time.Second, in storehouse face using the spraying of mist machine is made, enter the spraying of firm position face using rotary mist machine of making,
Its shortcoming is to make that mist acc power is larger, spread of spray is limited, and is sprayed in its rotary course and only spray to the front of shower nozzle, and shower nozzle is left
Right hand side air is in drying regime, can not accomplish around the face of storehouse constantly in spraying.
Utility model content
The purpose of this utility model is, there is provided a kind of Construction of Rolled Concrete Dam storehouse face miniclimate heat sink.With solution
The problem of certainly rolled concrete cylinder surface environment temperature controls in Civil Engineering hydroelectric project Construction of Rolled Concrete Dam.
The technical solution of the utility model：
A kind of Construction of Rolled Concrete Dam storehouse face miniclimate heat sink, including two sections of symmetrically arranged spraying water pipes；Two
For the symmetrically arranged spraying water pipe of section through fixed fixation with steel wire on stretching wire rope, stretching wire rope both ends are fixed on two sides dam abutment
On；Spraying water pipe one end is inlet opening, and the other end is closed through plug；It is equally distributed provided with one group along spraying water pipe length direction
Hole for water spraying.
Compared with prior art, the utility model can make air in the certain limit of storehouse face top be in large area spraying
In microclimate environment, spray cooling system is dispersed into the water particulate in air, and ring around a large amount of is absorbed during vaporization
Heat in border, so as to reduce ambient temperature, storehouse face surrounding air cooling-down effect is notable for evaporation cooling.In the utility model
Steel wire rope be fixed on main support of the two sides dam abutment as spraying water pipe, overall structure is stable.The coagulation of the certain elevation of dam
It is i.e. removable after dam abutment steel wire rope fixing end is released after the completion of soil pours, adjust convenient, low engineering cost.

Fig. 2 is the utility model application example Construction of Rolled Concrete Dam vertical section schematic diagram；
Fig. 3 is the utility model application example Construction of Rolled Concrete Dam schematic cross section.
In figure mark for：1- spraying water pipes, 2- stretching wires rope, 3- fix steel wire, 4- hole for water sprayings, 5- plugs, 6- water inlets
Hole, 7- concrete, 8- constructions storehouse face, 9- miniclimates heat sink, 10- attractive joints, 11- excavation lines.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples, but not as new to this practicality
Any restrictions of type.
A kind of Construction of Rolled Concrete Dam storehouse face miniclimate heat sink, as shown in Figure 1：Including two sections of symmetrically arranged sprays
Fog pipe 1；Two sections of symmetrically arranged spraying water pipes 1 are fixed on stretching wire rope 2 through fixed steel wire 3, the both ends of stretching wire rope 2
It is fixed on the dam abutment of two sides；The one end of spraying water pipe 1 is inlet opening 6, and the other end is closed through plug 5；Along the length direction of spraying water pipe 1
Provided with one group of equally distributed hole for water spraying 4.
Embodiment
The construction cross section signal of this example RCCD is as shown in Figure 3.Spill broken line in Fig. 3 is excavation line 11,
Fill concrete 7 between spill broken line, concrete are roller compaction constructions in layer, and attractive joint 10 is left in grinding coagulation soil.
For miniclimate heat sink 9 of the present utility model positioned at the top of construction storehouse face 8, the distance A of distance construction storehouse face 8 is 30~50m.Construction
Storehouse face 8 is as roller compaction construction process is constantly elevated, therefore miniclimate heat sink 9 of the present utility model also should be with construction
The rise in storehouse face 8 constantly raises.Fig. 2 is application example Construction of Rolled Concrete Dam vertical section schematic diagram of the present utility model, by
Fig. 2 is visible, during concrete application, can use multiple miniclimate heat sinks 9 of the present utility model according to dam facing width, be adopted in Fig. 2
With three miniclimate heat sinks 9 of the present utility model, the spacing B between each miniclimate heat sink 9 is 6~8m.Greatly
Dam upstream outermost device spread of spray need to cover dam upstream face, and dam downstream outermost device spread of spray need to cover dam
Downstream face.The structural representation of miniclimate heat sink 9 of the present utility model is as shown in figure 1, including two sections of symmetrically arranged sprays
Fog pipe 1；Two sections of symmetrically arranged spraying water pipes 1 are fixed on stretching wire rope 2 through fixed steel wire 3, the both ends of stretching wire rope 2
It is fixed on the dam abutment of two sides；The one end of spraying water pipe 1 is inlet opening 6, and the other end is closed through plug 5；Along the length direction of spraying water pipe 1
Provided with one group of equally distributed hole for water spraying 4.As seen from Figure 1, two sections of spraying water pipes 1 are included in this example, two sections of spraying water pipes 1
