Description
Technical field
The utility model belongs to building field, the device for being related to mine, adding concrete accelerator in Tunnel Engineering, specifically
It is liquid accelerator adding set in a kind of dry pressure spray process that ground, which is said,.
Background technique
Mine, railway tunnel excavation work in for Strengthening Tunnel palisades, prevent rock weathering from falling off and collapse with roof fall
Side, while the safety in order to guarantee constructing tunnel workspace pass through concrete by carrying out whole dry spray supporting to digging laneway
Mode on the metope of tunnel is ejected by reinforcing laneway.
Currently, dry spray supporting is mostly to add concrete ejection supporting using dry powder accelerator.For a long time, dry pressure spray process
Using dry powder accelerator, dry powder accelerator dust is big, especially influences on mine down-hole operating environment very big.In advance by dry powder speed
Solidifying agent is mixed in concrete drier in advance in proportion, since siccative is more during spice, dry powder accelerator during spice
With sandstone cement is full and uniform mixes bad control, the general springback capacity of concrete sprayed to metope is big, causes unnecessary
Waste of material, and because dry powder accelerator dust is big, site environment is influenced greatly, site operation personnel's operating environment is poor, mixes
Expect cumbersome, so that underground driving, production efficiency substantially reduce, and not only dirty but also tired operational procedure can not change.
Utility model content
The utility model to solve the above-mentioned problems, provides liquid accelerator adding set in a kind of dry pressure spray process.
The technology employed by the present utility model is liquid accelerator adding set in a kind of dry pressure spray process, including speed
Container is added in solidifying agent, and the one of accelerator addition container is terminated with air hose connecting tube, and accelerator addition the another of container is terminated with
Accelerator delivery pipe, the top that accelerator adds container add funnel equipped with accelerator, are equipped with ball valve in air hose connecting tube,
Non-return valve is installed in accelerator delivery pipe.
Further, the outlet of non-return valve connects a pipeline, and triple valve, the entrance water receiving of triple valve are equipped in the pipeline
It manages, liquid flow control valve is installed on water pipe.
Preferably, accelerator delivery pipe is located at the lower part of accelerator addition container, and the outlet of triple valve connects spray by pipeline
Penetrate head.
Further, accelerator addition container is located on pedestal.
Further, accelerator addition lower portion is seamless steel pipe, which is provided with control valve.
The utility model has the beneficial effects that the utility model reasonable utilization air hose connecting tube pressure wind realize it is quantitative defeated
Liquid accelerator is sent, is adjusted convenient for adjusting conveying capacity, completely quick substitution dry powder accelerator is more suitable for dry pressure spray process, reduces dry
Powder accelerator spice link reduces material spray dust, improves working environment at coal mines, in addition effectively strengthens concrete and accelerator
Mixing reduces concrete springback amount.The utility model structure is simple, and installation is simple and convenient, and time and labour saving is laborsaving.

Specific embodiment
The utility model is further explained and is illustrated with reference to the accompanying drawing；
As shown, liquid accelerator adding set in a kind of dry pressure spray process, including accelerator add container 1, it is located at
On pedestal, one end of accelerator addition container 1 is given a dinner for a visitor from afar pipe connected pipe 3, another termination accelerator delivery pipe 4, upper termination accelerator
Add funnel.It is seamless steel pipe that accelerator, which adds funnel, is equipped with the ball valve of Dg25 thereon.Wherein, air hose connecting tube is seamless
Steel pipe is also equipped with the ball valve of Dg25 thereon, and accelerator delivery pipe is seamless steel pipe, is equipped with non-return valve in accelerator delivery pipe
6.The outlet of non-return valve connects a pipeline, is equipped with triple valve 8 in the pipeline, the entrance water receiving pipe 7 of triple valve, installs on water pipe 7
There is liquid flow control valve 10.Accelerator delivery pipe 4 is located at the lower part of accelerator addition container, and the outlet of triple valve 8 passes through pipe
Road connects injector head 9.Entire accelerator addition container is located on pedestal.Pedestal 5 is diameter 18mm, the reinforcing bar four of length 500mm with
The bracket being welded, it is diameter 200mm that accelerator, which adds container, and the cylindrical type accumulator tank of high 300mm, capacity is
0.00942m³.Accelerator add container be it is hollow, length includes that air hose connecting tube and accelerator delivery pipe overall length are 500mm.
Embodiment 1
The non-return valve on the ball valve and accelerator delivery pipe in air hose connecting tube is closed first, opens accelerator addition leakage
The ball valve of bucket, adds funnel adding liquid accelerator by accelerator, the ball valve of accelerator addition funnel is closed after addition, then
The ball valve in air hose connecting tube is opened, realizes that quantitative conveying is centainly dense by controlling to adjust the non-return valve in accelerator delivery pipe
The accelerator of degree.
Embodiment 2
The non-return valve on the ball valve and accelerator delivery pipe in air hose connecting tube is closed first, opens accelerator addition leakage
The ball valve of bucket, adds funnel by accelerator and adds dry powder accelerator, the ball valve of accelerator addition funnel is closed after addition, then
The ball valve in air hose connecting tube is opened, the non-return valve adjusted in accelerator delivery pipe is opened, realizes quantitative conveying a certain concentration
Accelerator, required according to the concentration of the accelerator of conveying, if in the case where too dense, opening the stream on triple valve inlet water pipe
A small amount of water is added while conveying accelerator to dilute accelerator in control valve, reaches requirement, uniform from injector head
It sprays.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solutions of the utility model, the technology of the art
