Abstract
A kind of tunnel trolley timing automatic water spray curtain device, effectively to solve the technical barrier that effective air, face working space temperature in the dust pollution hole in area surface construction are excessive, first lining spray block maintenance efficiency is low.Including the sparge pipe being fixedly installed on tunnel trolley front end face, rear end face and top end face, each sparge pipe extends along the end profile of tunnel trolley, is arranged at intervals three-way connection on sparge pipe, atomizer is set on each three-way connection.The rear end of the sparge pipe is sealed end, and front end is incoming end, and incoming end is linked in sequence autocontrol valve, geomantic omen mixer by pipeline, the external high-pressure air hose of geomantic omen mixer, high-pressure water pipe.
Description
Technical field
Constructing metro tunnel is the utility model is related to, more particularly to a kind of tunnel trolley timing automatic water spray curtain device,
The depositing dust in area surface construction, cooling and the maintenance that structure is cut to tunnel lining can be achieved.
Background technology
In subway tunnel tunneling process, in order to ensure good, safe construction operation environment, it is necessary to monitor in real time in hole
Indices, and it is mingled with dust air in the purification tunnel face surface construction that takes measures, and to face high-temperature operation space
Cool down.It is feasible measure using water mist heavy curtain depositing dust, cooling.
Water mist heavy curtain using constructing tunnel high-pressure blast and high pressure water, you can using between gas medium and liquid medium
Mutual extruding, accelerate or shear action atomize the liquid into be formed high pressure water particulate mist shield tape prevent dust to external diffusion and with
Water particle landing, and hydrone evaporation can be made full use of to absorb amount of heat, droplet rapid vaporization, becomes water vapour, so that
The humidity increase of air, temperature drop, also do with good maintenance just lining concrete using the continuous diffusion of water mist, evaporation.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of tunnel trolley timing automatic water spray curtain device, with
Effectively air, face working space temperature are excessive in dust pollution hole in effective solution area surface construction, first lining spray block is foster
Protect the low technical barrier of efficiency.
Technical solution is as follows used by the utility model solves the technical problem：
A kind of tunnel trolley timing automatic water spray curtain device of the utility model, it is characterized in that：Including being fixedly installed in
Sparge pipe on tunnel trolley front end face, rear end face and top end face, each sparge pipe extend along the end profile of tunnel trolley, water spray
Three-way connection is arranged at intervals on pipe, atomizer is set on each three-way connection；The rear end of the sparge pipe is sealed end, and front end is
Incoming end, incoming end are linked in sequence autocontrol valve, geomantic omen mixer by pipeline, the external high-pressure air hose of geomantic omen mixer,
High-pressure water pipe.
The beneficial effects of the utility model are to install timing automatic water spray curtain device, collection depositing dust, drop beneficial to tunnel trolley
Temperature, conserve multiple function, simple in structure, simple operation；Operation cost is cheap, can automate spray curtain, and effect is bright
It is aobvious, highly practical.
Brief description of the drawings
This specification includes such as next width attached drawing：
Fig. 1 is a kind of elevational schematic view of tunnel trolley timing automatic water spray curtain device of the utility model.
Component name and corresponding mark are shown in figure：Tunnel trolley 10, sparge pipe 20, incoming end 21, sealed end 22,
Three-way connection 23, atomizer 24.
Embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings.
With reference to Fig. 1, a kind of tunnel trolley timing automatic water spray curtain device of the utility model, including it is fixedly installed in tunnel
Sparge pipe 20 on 10 front end face of road trolley, rear end face and top end face, each sparge pipe 20 prolong along the end profile of tunnel trolley 10
Stretch, three-way connection 23 is arranged at intervals on sparge pipe 20, atomizer 24 is set on each three-way connection 23.After the sparge pipe 20
To hold as sealed end 22, front end is incoming end 21, and incoming end 21 is linked in sequence autocontrol valve, geomantic omen mixer by pipeline,
The external high-pressure air hose of geomantic omen mixer, high-pressure water pipe.It can be set in advance between spray time, spray time by autocontrol valve
Every, spray water mist size, realize that high-efficiency automatic works, can imitate effectively empty in the dust pollution hole solved in area surface construction
The technical barrier that gas, face working space temperature are excessive, first lining spray block maintenance efficiency is low.
The sparge pipe 20, three-way connection 23 use atactic copolymerized polypropene material, sparge pipe 20 and three-way connection 23
Sweat soldering.
Some principles of the utility model described above that simply explains through diagrams, are not intended to the utility model being confined to
In shown and described concrete structure and the scope of application, therefore every corresponding modification for being possible to be utilized and equivalent,
Belong to the apllied the scope of the claims of the utility model.
