Abstract
The utility model discloses a cavern top arch concrete backfilling device, and belongs to top arch concrete backfilling devices for caverns in hydraulic and hydroelectric engineering. The cavern top arch concrete backfilling device comprises a material containing hopper, a concrete tank and a discharge pipe, wherein the material containing hopper, the concrete tank and the discharge pipe are connected in sequence, a gas supply pipe is arranged on the upper portion of the concrete tank, and the gas supply pipe is connected with an air compressor. The cavern top arch concrete backfilling device has the advantages that concrete is pressed to the backfilling portion on a top arch through air pressure generated by the air compressor after being contained in the concrete tank so that the compaction of the concrete can be ensured, the construction process does not need a large number of tubular products for erecting bearing scaffolds, no matched concrete pump is needed, and therefore the operation is easy to conduct, the construction cycle is short, the practicability is high, and cost is saved.
Description
Technical field
The utility model belongs to construction work concrete construction technology field, relates in particular to the crown concrete construction technology field of underground chamber, particularly a kind of cavern's crown concrete backfill apparatus.
Background technology
The crown permanent structure traditional approach of underground construction cavern is concrete lining, for meeting the engineering embedded part, needs is installed, and at crown, usually reserves some holes, after the embedded part installation, then adopts concrete to carry out backfill construction to reserving hole.Preformed hole construction is because engineering quantity is little, adopts traditional arch top concrete lining will use a large amount of tubing to set up load-bearing scaffold, supporting concrete pump etc., and long construction period, and construction cost is high.
Summary of the invention
Problem to be solved in the utility model is exactly that a kind of simple to operate, short construction period, cost-saving concrete backfill equipment are provided for above deficiency.
It comprises bucket, concrete tank and discharge nozzle, and bucket, concrete tank and discharge nozzle are connected successively, on concrete tank top, air supply pipe is set, and air supply pipe connects air compressor machine.
The beneficial effect compared with prior art the utlity model has is:
1,, contain concrete in concrete tank after, the air pressure that utilizes air compressor machine to produce is depressed into crown backfill position by concrete, guarantees concrete density.
2, do not need to use a large amount of tubing to set up the load-bearing scaffold in work progress, do not need supporting concrete pump, simple to operate, short construction period, strong adaptability, cost-saving.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to Fig. 1, the utility model comprises bucket 1, concrete tank 8 and discharge nozzle 10, and bucket 1, concrete tank 8 and discharge nozzle 10 are connected successively, on concrete tank 8 tops, air supply pipe 7 is set, air supply pipe 7 connects air compressor machine, and air supply pipe valve 5 also is installed on air supply pipe 7.
Described bucket 1 and concrete tank 8 welding the first flange 3 suitable for reading, 8 of bucket 1 and concrete tanks arrange between butterfly valve 2, the first flange 3 and butterfly valve 2 and adopt bolt 4 to connect.With bolts between welding the second flange 9, the second flange 9 on concrete tank 8 bottoms and discharge nozzle 10.
Stack 6 is installed on air supply pipe 7, on stack 6, air gauge is installed.
Described discharge nozzle 10 afterbodys arrange flexible pipe 11 to crown backfill position.
While using the utility model, its operating process is:
1, concrete is entered to concrete tank 8 through bucket 1, the charge position is no more than 2/3 of concrete tank volume;
2, close butterfly valve 2;
3, open air compressor machine;
4, the air gauge connected when stack 6 shows that pressure reaches 0.4Mpa when above, opens air supply pipe valve 5;
5, the concrete of concrete tank 8 interior splendid attires enters crown backfill position under the effect of air pressure.
