Description
Technical Field
The utility model relates to a shield constructs quick-witted seal technical field, specifically is shield constructs quick-witted inflatable seal protection gasbag.
Background
A shield machine is a tunnel boring machine using a shield method. The shield construction method is a shield (referring to a supporting segment) for constructing (laying) a tunnel while a heading machine is heading, is different from an open construction method, and is a main equipment for current tunnel construction. The basic working principle of the shield tunneling machine is that a cylindrical steel component is pushed forwards along the axis of the tunnel to excavate soil. The casing of the cylinder assembly, the shield, acts as a temporary support for the excavated, not yet lined tunnel section, bearing the pressure of the surrounding soil layers and sometimes also the groundwater pressure and the water that is trapped outside. The operations of digging, dumping, lining and the like are carried out under the shield of the shield.
In the tunnel engineering, the waterproof technology of the shield tunnel is of great importance, but the sealing device in the shield machine plays a vital role. If reliable waterproof and sealing measures are not available, groundwater can invade, once an accident occurs, when dynamic sealing between the middle shield and the front shield is damaged, due to the fact that pressure difference between the inside and the outside of a shell of the shield machine exists in the construction process, groundwater and soil and sand in the gap between the middle shield and the front shield can permeate into the tail shield, the shield machine cannot normally work, and meanwhile great threat is brought to personal safety of workers.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a shield constructs quick-witted inflatable seal protection gasbag in order to solve above-mentioned problem.
The utility model discloses a following technical scheme realizes above-mentioned purpose, and shield constructs quick-witted inflatable seal protection gasbag, including a structure main part, the structure main part is by protection gasbag and the sealing washer of built-up connection with it, be equipped with a plurality of extrusion hole on the protection gasbag, sealing washer is hollow structure, just sealing washer outer wall one side is equipped with the charging connector, the charging connector with sealing washer vulcanizes the connection.
Preferably, a gasket is arranged at the joint of the inflating nozzle and the inflating sealing ring.
Preferably, the wall thickness of the inflatable sealing ring ranges from 0.5mm to 20mm, the width of the protection air bag ranges from 10mm to 100mm, and the thickness ranges from 3mm to 60 mm.
Preferably, a nut is arranged on the inflating nozzle.
Preferably, the protective airbag is a rubber airbag.
Preferably, the extrusion holes are uniformly arranged in the protective airbag.
Preferably, a plurality of air outlet holes are formed in the connecting end of the inflating nozzle and the inflating sealing ring.
The utility model has the advantages that: by arranging the inflatable sealing protection air bag, a reliable waterproof and sealing system is provided for the shield machine, underground water is prevented from invading a tunnel, the stability of an internal structure is improved, and the working performance of the shield machine is improved; the inflatable sealing protection air bag is a rubber air bag and has the characteristics of wear resistance, oil resistance, skid resistance, corrosion resistance and aging resistance; simultaneously, the sealing ring is arranged to be an inflatable sealing ring, the size of the sealing ring can be controlled through inflation and deflation, and the inflatable sealing ring is convenient to mount and dismount.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure: 1. a protective airbag; 2. extruding the hole; 3. an inflatable seal ring; 4. a gasket; 5. a nut; 6. an air charging nozzle.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the shield machine inflatable sealing protective airbag comprises a structural main body, the structural main body is composed of a protective airbag 1 and an inflatable sealing ring 3 connected with the protective airbag in a combined manner, a plurality of extrusion holes 2 are formed in the protective airbag 1, the inflatable sealing ring 3 is of a hollow structure, an inflating nozzle 6 is arranged on one side of the outer wall of the inflatable sealing ring 3, and the inflating nozzle 6 is connected with the inflatable sealing ring 3 in a vulcanization manner.
In addition, a gasket 4 is arranged at the joint of the inflating nozzle 6 and the inflating sealing ring 3; the wall thickness range of the inflatable sealing ring 3 is 0.5mm to 20mm, the width range of the protective air bag 1 is 10mm to 100mm, and the thickness range is 3mm to 60 mm; a nut 5 is arranged on the charging connector 6; the protective air bag 1 is a rubber air bag; the extrusion holes 2 are uniformly arranged in the protective air bag 1; and a plurality of air outlet holes are formed at the connecting end of the inflating nozzle 6 and the inflating sealing ring 3.
It should be noted that the inflatable sealing ring 3 is a hollow structure, and the interior of the hollow structure can be inflated and deflated through the inflating nozzle 6.
The working principle is as follows: when the device is installed, the non-inflated inflatable sealing ring 3 is arranged at a sealing position, then the inflatable sealing ring 3 is inflated through the inflating nozzle 6, and the inflatable sealing ring 3 can expand after being inflated, so that the sealing effect is achieved; when the inflatable sealing ring is disassembled, the gas in the inflatable sealing ring 3 is discharged through the inflating nozzle 6, and the deflated inflatable sealing ring 3 is reduced, so that the disassembly is convenient; once an accident occurs, the protective air bag 1 can play a role in blocking the infiltration of underground water and soil sand, and the life safety of workers is guaranteed.
