The tunnel heat preservation door is simple in structure assembly, light in weight, durable and good in heat preservation effect under the condition that passage, smoke exhausting and ventilation are guaranteed completely and provides a good working environment for construction of a tunnel in winter.
Description
Technical field
The utility model relates to the constructing tunnel field, particularly a kind of tunnel insulation door.
Background technology
Constructing tunnel condition in winter cold and stern is relatively harsher, how to guarantee that in the constructing tunnel process vehicle crew is normally current, discharges fume effectively and timely, ventilates, and can realize the insulation to the tunnel again, needs a kind of tunnel insulation device usually.
The utility model content
The purpose of the utility model is: a kind of tunnel insulation door is provided, is guaranteeing that fully high insulating effect is for the tunnel winter construction provides good working environment under the condition of passing through, discharge fume, ventilating.Said tunnel insulation door has characteristics such as simple in structure, in light weight, durable in use, practical.
The tunnel insulation door master door that the utility model provides is characterized in that: the structure of said thermal insulation door comprises, main body frame 1, vertical part 2, gate 3, wicket 4, ventilation opening 5, exhaust opening 6, fixture 8, steel mesh reinforcement, insulation filling materials, the tarpaulin of joining;
Said main body frame 1 is made up of double member, and said double member connects through vertical couplet part 2 welding or flange, and said main body frame 1 bottom adopts anchor bolt or anchor bar to be fixed in the inverted arch backfill 7 through flange;
Said gate 3 is the double door double-decker, is connected with main body frame 1 through Xiao's bolt, forms swivel structure; Said wicket 4 is the single open-door double-decker, is connected with main body frame 1 through Xiao's bolt, forms swivel structure;
Said ventilation opening 5 adopts reinforcing bar to be welded, and is connected with steel mesh reinforcement and fixes, and its diameter is the ventilating bag diameter, i.e. Φ=180cm or Φ=150cm; Said exhaust opening 6 adopts reinforcing bar to be welded, and is connected with steel mesh reinforcement and fixes, and its diameter is Φ=100cm or Φ=120cm; Said steel mesh reinforcement is Φ=8mm reinforcing bar for adopting diameter, and size of mesh opening is 10cm * 10cm, is welded in main body frame 1 outside, and insulation filling materials is played the effect that retaining protects;
Said insulation filling materials adopts compositions such as straw or maize straw, clogs between two-layer steel mesh reinforcement, and the filling compactness should be moderate, and is too not closely knit or loose, has insulation, cushioning effect; Said tarpaulin is fixed on the steel mesh reinforcement closely, plays the modification insulation effect.
The said tunnel insulation door of the utility model also is provided with time door, and said time door is provided with skeleton 01, suspension hook 02, shelter 03; Said suspension hook 02 is fixed in skeleton 01; Said shelter 03 is linked in suspension hook 02; Shelter 03 is that separation becomes two parts to break off with the tunnel center line; Be spaced a distance between said the Men Yuzhu door, gradation is open.
Description of drawings
Fig. 1 is the utility model tunnel insulation door master door sketch map;
Fig. 2 is the utility model tunnel insulation Men Cimen sketch map.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described: be as shown in Figure 1; In the utility model preferred embodiment, be main body frame 1 with double steel pipe frame, 1 of main body frame adopts steel pipe to be welded to connect; 1 liang of lateral surface of main body frame adopts diameter of phi=8mm steel mesh reinforcement welding; Insulation filling materials such as filling straw and sawdust between the reinforced mesh, thermal insulation door is provided with the twice inlet/outlet, is that vehicle pass-through Men Rutu gate 3 adopts double door together; Another road is that walk Men Rutu wicket 4 adopts single open-door, and thermal insulation door all is provided with gravity vent 5 and steam vent 6 on top.
The processing and the installation process of said tunnel insulation door master door: at first the welding assembly main body frame 1, in assembling, the welding process, for guaranteeing the precision of each member, can delimit scantling figure prior to ground, and accurately locatees; In the welding assembly, carry out the horizontal vertical member earlier, carry out fan-shaped component again and install, carry out crossing members at last and install; After treating main body frame 1 assembled, hole inner side main body framework 1 is lifted fixing, top and side adopt anchor bolt and " U " shaped steel muscle to fix; Footing adopts expansion bolt to be fixed in inverted arch and fills 7 end faces; After hole inner side main body framework 1 installs, carry out 1 lifting of hole outside main body framework, and adopt the vertical part 2 that joins to be welded to connect; Behind to be welded the finishing; Also adopt anchor bolt and " U " shaped steel muscle to fix to outside main body frame, gate 3 and wicket 4 direct machine-shaping in ground carry out integral hoisting and install; Steel mesh reinforcement 7 adopt shaping nettings or field machining all can, colligation or be welded in the outside of main body frame 1, size of mesh opening adopts 10cm * 10 cm to be advisable; Ventilation opening 5 adopts reinforcing bar to be welded, and is fixed on the reinforced mesh, is used for the ventilating bag inlet port, and its diameter is ventilating bag diameter 1.8m or 1.5m; Exhaust opening 6 is prone to adopt reinforcing bar to be welded, and is fixed on the reinforced mesh, and its diameter can be confirmed according to tunnel advanced depth, smoke evacuation, exhaust situation; Insulation filling materials can be selected straw or maize straw etc. for use, clogs between two-layer steel mesh reinforcement, and the filling compactness should be moderate, and is too not closely knit or loose, so that play the effect of anti-gas shock insulation the time; Tarpaulin is close to the steel mesh reinforcement outside, plays insulation, decoration function.
Said tunnel insulation Men Cimen is as shown in Figure 2; The installation and processing process is: apart from the about 40m of main door place time door is being set; Prior to suspension hook 02 of every interval 50～100cm welding on the skeleton 01, skeleton 01 adopts expansion bolt to weld fixing to skeleton 01 after in the hole, circularizing state naturally along lining; During suspension shelter 03, be that separation becomes two parts to break off with the tunnel center line.
Between promptly main door of twice thermal insulation door and inferior door, be provided with stove; Homonymy stove spacing is 10m, and thermal insulation door also is 10m apart from stove, and the stove burning smoke is discharged outside the hole through chimney; Note adopting when chimney passes thermal insulation door heat proof material such as asbestos shingle to protect isolation, in case fire.
The shelter 03 of thermal insulation door time door is in open mode to lifting in the work progress, so that the heating installation that heating is provided with transmits inwardly; Guarantee the construction temperature in the tunnel, during vehicle pass-through, make time door be in closed condition earlier; Gate on the open main door treats that vehicle passes through main door; Close main door and open time door again, thereby prevent that cold air from transmitting in the tunnel, the construction walk is accomplished to shut the door after you in the wicket of main door.
The preferred embodiment that the above is merely the utility model is not in order to limit the application range of the utility model; All other do not break away from the equivalence of being accomplished under the essence that the utility model discloses and change or modify, and all should be included in following claims scope.
