Description
Technical field
This utility model relates to high pressure rubber airbag technology field, particularly relates to a kind of inflated type tunneling shield and seals high pressure rubber air bag.
Background technology
Along with carrying out of China's city underground engineering, advanced tunneling shield technology obtains universal and extensively application.In construction of underground tunnel equipment, shield machine is indispensable large-scale heading equipment, shield machine not only volume is big, equipment self-weight is big, and the sophisticated equipment of its outfit is many, operating process is complicated, especially enter hole at shield launching and arrive the construction link appeared, it is desirable to there is higher operation level and strict operating process.More complicated in some subsurface geology condition, such as high water level, weak soil fine sand layer etc., for ensureing equipment and the safety of engineering, the seal construction of the export & import of its shield machine is extremely important, if misoperation or sealing device lost efficacy, easily causes the infiltration on stratum, gushes the accident such as sand, landslide, thus cause export & import failure, cause the major accidents such as property economic loss, construction delay, even casualties.
On the export & import sealing means of shield machine, have multiple method, as use rubber curtain fabric swatch seal, due to sealing plate piecemeal arrange, the gap between plate is many, causes sealing effectiveness poor, and it is loaded down with trivial details to construct, and parts installing engineering amount is big；Also there is employing freezing method that stratum is reinforced, play certain sealing effectiveness, but its energy waste is serious, and long construction period, expenses is big.
Utility model content
The purpose of this utility model is to solve shortcoming present in prior art, and a kind of inflated type tunneling shield proposed seals high pressure rubber air bag.
To achieve these goals, this utility model adopts the technical scheme that
A kind of inflated type tunneling shield seals high pressure rubber air bag, including shield machine shell, the side of described shield machine shell is provided with rubber slab, described rubber slab is provided with high pressure rubber air bag away from the side of shield machine shell, described high pressure rubber air bag is installed in the groove of portal body of wall, it is interspersed with Grouting Pipe in described portal body of wall, the two ends of described rubber slab are provided with adjustable support, the side of described adjustable support offsets with portal body of wall, described adjustable support is provided with pressing plate away from the side of rubber slab, described pressing plate is provided with securing member away from the side of adjustable support, described securing member is connected through adjustable support and pressing plate with rubber slab.
Preferably, one end of described Grouting Pipe is positioned at the top of shield machine shell.
Preferably, the side of described high pressure rubber air bag is provided with aerating device.
Preferably, described securing member uses lock-screw.
In this utility model, this employing inflated type high pressure rubber air bag achieves the sealing of turnover portal and shield machine shell, infiltration is prevented to gush the generation of sand, compared with traditional sealing device, the equipment that this encapsulating method needs is few, install simple to operate, earthwork construction amount is few, preferable sealing effectiveness can be realized, improve efficiency of construction, reduce construction cost, the performance of high pressure rubber air bag product and safety are high, overall plan good reliability, it is greatly reduced the risk probability that construction seepage accident occurs, it is that the one to tradition portal sealing means is improved, gradually it is widely applied in shield machine export & import Seal.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of inflated type tunneling shield that the utility model proposes seals high pressure rubber air bag.
In figure: 1 portal body of wall, 2 Grouting Pipe, 3 high pressure rubber air bags, 4 adjustable supports, 5 securing members, 6 pressing plates, 7 rubber slabs, 8 shield machine shells.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.
With reference to Fig. 1, a kind of inflated type tunneling shield seals high pressure rubber air bag, including shield machine shell 8, the side of shield machine shell 8 is provided with rubber slab 7, rubber slab 7 is provided with high pressure rubber air bag 3 away from the side of shield machine shell 8, the side of high pressure rubber air bag 3 is provided with aerating device, high pressure rubber air bag 3 is installed in the groove of portal body of wall 1, Grouting Pipe 2 it is interspersed with in portal body of wall 1, one end of Grouting Pipe 2 is positioned at the top of shield machine shell 8, the two ends of rubber slab 7 are provided with adjustable support 4, the side of adjustable support 4 offsets with portal body of wall 1, adjustable support 4 is provided with pressing plate 6 away from the side of rubber slab 7, pressing plate 6 is provided with securing member 5 away from the side of adjustable support 4, securing member 5 uses lock-screw, securing member 5 is connected through adjustable support 4 and pressing plate 6 with rubber slab 7.
Embodiment
When there is no groove on portal body of wall; on mounting structure; outside turnover panel uses hinged; to realize the protection to inner side sealing cord plate; high pressure rubber air bag is arranged in inner side, does not carry out the slot grooving of body of wall, and only carries out interim fixing by rubber slab; the sealing brush of inner side realizes striking off shield machine housing appearance foreign material, prevents sharp objects from scratching high pressure rubber air bag.
This utility model shifts to an earlier date outer baffle in hole is installed；Fix the high pressure rubber air bag 3 without gaseity in groove with rubber slab 7, left and right lap position is arranged suitable；Fixing rubber slab 7 is installed, connects securing member；Connect loading line and source of the gas；When cutter head of shield machine arrive portal mouth with air bag delivery position after, regulate the height of outer side shield, make the gap between baffle plate and cutterhead the least；Start two high pressure rubber air bags 3 to be inflated simultaneously, after reaching design work pressure, stop inflation, close valve, record force value；Shield machine moves on, and progressively appears, and during slowly appearing, observes the force value in high pressure rubber air bag 3 at any time, once occur that seepage gas should be inflated in time, should exit when there is excess pressure, it is proposed that uses the relief valve of configuration to carry out high voltage control.
The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; conceive equivalent or change in addition according to the technical solution of the utility model and utility model thereof, all should contain within protection domain of the present utility model.
