Description
Technical field
The utility model is related to the realm of building construction, more particularly to appts. for transferring ready-mixed concrete.
Background technology
Concrete chute is mainly used for the downward delivering concrete under ground portion structure construction, and conveying speed can be with
Reach average 150m per hour3.Dead weight and the mobility of concrete is utilized in the mode of movement of this concrete, has construction
Conveniently, the advantages of low manufacture cost.
Common concrete chute is chiefly used in the under ground portion structure construction of new building, for example, being completed in excavation of foundation pit
Elephant trunk is set up by way of setting up chute holder afterwards, the gradient can be selected 1:2 (depth is within 20m) or 1:3 (depth exists
Between 20-30m).
However, when stating elephant trunk delivering concrete in use, to avoid causing plugging and improving transfer efficiency, it is desirable that coagulation
The slump of soil is not less than 180mm, to ensure it with enough mobility.When the slump of concrete is less than 180mm, by
It is relatively low in the mobility of concrete, it is easy to cause caking and blocks chute.Therefore, above-mentioned elephant trunk cannot be satisfied slump and be less than
The conveying requirement of the concrete of 180mm.

Very little is 50mm*50mm*5mm.
Above-mentioned appts. for transferring ready-mixed concrete 1 can the directly discharging at lower hopper 12 after concrete tank is marched into the arena, you can edge
It the first elephant trunk 10, first buffering section the 20, second elephant trunk 30, second buffering section 40 and discharge port 60 conveys downwards, in concrete
After floor needed for reaching, manual labor's vehicle or fixed pump is coordinated to complete horizontal feed.By being arranged vertically concrete conveyance dress
1 is set, increases the downward kinetic energy of concrete, reaches downward vertically transport of the lazy flow concrete without additionaling power, simultaneously because
Without setting up holder, the space needed for arrangement appts. for transferring ready-mixed concrete 1, and easy access are saved.
In addition, use above-mentioned appts. for transferring ready-mixed concrete 1 successfully by slump for the lazy flow concrete of 130 ± 20mm from
Ground (absolute altitude is -0.10m) is delivered to 14 layers of underground (absolute altitude is -48.78m), and concrete does not occur segregation phenomenon, can be direct
For floor leveling, leads wall and the techniques such as pour.
The application construction method of above-mentioned appts. for transferring ready-mixed concrete 1 is illustrated below in conjunction with Fig. 1-Fig. 6.
As shown in fig. 6, the application construction method of the appts. for transferring ready-mixed concrete 1 of an embodiment includes the following steps：
Step S600, by lower hopper 12, the first elephant trunk 10, first buffering section the 20, second elephant trunk 30, second buffering section 40,
Discharge port 60 and fixed frame 50 connect, and form appts. for transferring ready-mixed concrete 1.Lower hopper 12, the first elephant trunk 10, first buffering section
20, the second elephant trunk 30, second buffering section 40 and discharge port 60 are in connected state.
Appts. for transferring ready-mixed concrete 1 is arranged vertically on existing structure by step S610 by fixed frame 50.Concrete is defeated
It send device 1 to be arranged using vertical mode, the potential energy of lazy flow concrete and dynamic transformation of energy can be maximally utilised, made
Appts. for transferring ready-mixed concrete 1 transports lazy flow concrete and is possibly realized.In the present embodiment, using expansion bolt by fixed frame 50
It is connect with existing structure.
Step S620 buffers the 20, second elephant trunk of section by concrete from discharging from lower hopper 12 through the first elephant trunk 10, first
30 and second buffer section 40, are most flowed out afterwards through discharge port 60, complete the conveying of concrete.Concrete tank can directly exist after marching into the arena
Discharging at lower hopper 12, you can achieve the effect that transport lazy flow concrete downwards.
The application construction method step of above-mentioned appts. for transferring ready-mixed concrete 1 is simple and convenient to operate, and is suitable for popularization and application.
Each technical characteristic of embodiment described above can be combined arbitrarily, to keep description succinct, not to above-mentioned reality
