The present invention relates to the realm of building construction, be mainly used in the open type shield machine in the constructing tunnel.
Technical background
In shield construction,, need to use the shield machine that is fit to driving for different geological conditions.On mixing stratum based on sandy gravel, especially run into erratic boulder content height, sand-pebble layer that the erratic boulder particle diameter is big, if adopt when closing chest formula shield machine driving and will bring many difficulties that are difficult to overcome, increase as required torque, thrust, cutter, cutterhead serious wear, the processing cost of big particle diameter cobble is big, and sedimentation is out of control, duration is delayed, cost increase etc.Sand-pebble layer behind anhydrous or precipitation adopts the open type shield machine of no cutterhead, can effectively solve above-described problem.But in the shield structure interval that needs precipitation to handle, the situation of water pocket, underground water rising may appear still behind the precipitation.If infiltration among a small circle can use suction pump that water is extracted out.If water yield is big, suction pump draining is in time perhaps gushed husky amount when big, can make operating personnel and back method, apparatus have security risk, how to avoid the generation of this type of risk, becomes a difficult point of open type shield-tunneling construction.
Summary of the invention
The utility model provides a kind of open type shield machine to gush husky sealing device with anti-water burst, can solve in the open type shield-tunneling construction security challenge of operating personnel and back method, apparatus when water burst taking place gushing sand effectively.
The present invention is made up of shield machine shell (1), seal diaphragm (2), hermatic door (3), hydraulic cylinder (4), mount pad (5), pin (6), axle head baffle plate (7), soket head cap screw (8), spring washer (9), plain washer (10), gland (11), pilot seal support (12), weather strip (13) and conveying worm (14).Weather strip (13) passes through soket head cap screw (8) with gland (11), spring washer (9) and plain washer (10) are fixed on pilot seal support (12) and go up the chute that composition can seal, hermatic door (3) is complementary with the size of chute, hermatic door (3) places in the chute, hermatic door (3) can slide in chute, weather strip (13) is pressed between hermatic door (3) and the pilot seal support (12) by gland (11), realize the sealing of hermatic door (3) in chute, hermatic door (3) is made up of two fans of symmetry, wherein a fan side has groove, can embed weather strip (13), realize the sealing of two fan hermatic door (3) jointing edges.Hermatic door (3) opening and closing under the effect of hydraulic cylinder (4), hydraulic cylinder (4) symmetric arrangement, hydraulic cylinder (4) is hinged on the mount pad (5) by pin (6) and axle head baffle plate (7) one ends, and the other end is hinged on the hermatic door (3).Conveying worm (14) passes seal diaphragm (2), and the shell of conveying worm (14) is fixed on the seal diaphragm (2).Mount pad (5) and pilot seal support (12) are fixed on the seal diaphragm (2).Seal diaphragm (2) is fixed on the shield machine shell (1).Behind the unearthed gate of closing hermatic door (3) and conveying worm (14), can seal the open type shield machine effectively in the anterior space of seal diaphragm (2), prevent that water burst from gushing sand and entering the shield machine rear portion.
During the open type shield-tunneling construction, operating personnel can opening encapsulation door (3) enter the shield machine front portion and carry out operation, when unexpected generation water burst gushes sand, operating personnel press the unearthed gate that control button cuts out hermatic door (3) and conveying worm (14), thereby seal diaphragm (2) is kept apart the front and rear of shield machine, water burst gushes the front portion that sand can only inject shield machine, and can't arrive the rear portion of shield machine, guarantees the safety of operating personnel and back method, apparatus.
The utility model provides a kind of simple in structure, low cost of manufacture, anti-water burst that security reliability is high to gush husky sealing device, can handle sudden a large amount of water burst timely and effectively and gush husky problem, avoid operating personnel and back method, apparatus generation safety issue, increase the safety of open type shield-tunneling construction.
