Description
Technical field
The present invention provides the mounting structure for strengthening the sealing of earth pressure balance sensor storehouse and its installation that a kind of shield machine uses
Method, belongs to shield-tunneling construction field.
Background technology
In shield machine construction, it is necessary to control the sedimentation on ground, it is necessary to which the pressure for controlling adjustment ton interior sealing cabin is that dynamic is flat
Weighing apparatus.Earth pressure balance sensor is housed, for detecting soil pressure, easy to monitor and adjust inside native storehouse in shield machine anterior shield
Pressure, to ensure that operating pressure balances outside shield in shield, avoids pressure differential from causing the security incidents such as landslide.To ensure the spirit of sensor
Quick property, design sensor storehouse are used to protecting and installing sensor.
For a long time, the mounting means of soil pressure case 1 is always the mounting means promoted by steel pipe, sees Fig. 1.It is this
Mounting structure is to be installed together sensor frame 2 and sensor overcoat 8, pushes foreboard to from shield wall direction.The installation of this mode
Although also installation sealing, because the steel pipe 3 as sensor storehouse is when with the welding of the anterior shield foreboard 5 of shield body, due to stress influence
Deform, or installation concentricity control is bad, causes sealing ring 6 to wear or in sealing contact bad, influences sealing effect, and then
Influence sensitivity and the service life of sensor.
The content of the invention
The present invention solves above-mentioned technical problem and provides a kind of mounting structure for strengthening earth pressure balance sensor storehouse sealing effect
And its installation method, realize good sealing effect.
The present invention solves the technical solution that technical problem uses：
The mounting structure for strengthening the sealing of earth pressure balance sensor storehouse that a kind of shield machine uses, it includes being arranged on the outside of sensor
Sensor frame and sensor sleeve, be equipped with steel pipe on the outside of sensor frame and sensor sleeve, the sensor frame outside is additionally provided with steel
Plate ring, steel plate ring outside are connected with the welding of anterior shield foreboard, and sealing ring, steel plate ring are equipped with the inside of steel plate ring and at sensor frame cooperation
Be connected with steel-pipe welding, the ring footpath of the steel plate ring is more than the wall thickness of steel pipe, and ensure steel plate ring with before steel pipe and anterior shield
Do not make a difference the deformation that sealing ring seals after plate welding.
Steel pipe holding tank is equipped with the inside of above-mentioned steel plate ring left end, steel tubing portions insertion steel pipe holding tank is interior and welds solid
Even.
Above-mentioned sealing ring interval setting is multiple, and ensures that both ends are at least set respectively at sensor frame and steel plate ring cooperation
One.
The installation method for strengthening the sealing of earth pressure balance sensor storehouse that a kind of shield machine uses, installation method use foregoing power
Profit requires the mounting structure for strengthening the sealing of earth pressure balance sensor storehouse that any shield machines of 1-3 use.
Beneficial effects of the present invention：
1st, installed using structure of the present invention, reduce the deflection of steel pipe, and steel plate wall thickness, welding deformation amount are small, will not cause to add
Work seals facial disfigurement, then sealing ring is not worn in installing, and contact is good, and sealing effect is improved；
2nd, by setting steel pipe holding tank, steel tubing portions insertion steel pipe holding tank is interior and welding is connected can strengthen welding effect；
Even if the 3rd, sealing ring both ends at sensor frame and steel plate ring cooperation at least set one respectively can ensure there is small change
Shape may also ensure sealing effect, and the welding of annular slab both ends may cause it to form arch bending, sealing ring is arranged on end
It can guarantee that sealing.
Brief description of the drawings
Illustrated below in conjunction with attached drawing with embodiment
Fig. 1 is the structure diagram of the prior art；
Fig. 2 is the structure diagram of the present invention.
Embodiment
Referring to the drawings 2, the mounting structure for strengthening the sealing of earth pressure balance sensor storehouse that a kind of shield machine uses, it includes setting
The sensor frame 2 and sensor sleeve 8 in the outside of sensor 1 are put, steel pipe 3, the biography are equipped with the outside of sensor frame and sensor sleeve
Steel plate ring 4 is additionally provided with the outside of sensor frame, is connected with the welding of anterior shield foreboard 5 on the outside of steel plate ring, matches somebody with somebody on the inside of steel plate ring with sensor frame
Sealing ring 6 is equipped with conjunction, steel plate ring is connected with steel-pipe welding, and the ring footpath of the steel plate ring is more than the wall thickness of steel pipe, and protects
Card steel plate ring and the deformation for the sealing ring sealing that do not make a difference after steel pipe and the welding of anterior shield foreboard.
During installation, steel pipe is welded together with an overall diameter for 260 steel plate, after processing at sealing hole, before being reloaded into
The hole for the diameter 260 opened on shield foreboard and welding, then the sensor frame installed is pushed to foreboard by shield wall direction below.Such a peace
Dress mode strengthens sealing effect because welding deformation amount reduces, and reducing influences transducer sensitivity.
Preferably, steel pipe holding tank is equipped with the inside of the steel plate ring left end, steel tubing portions are inserted into steel pipe holding tank simultaneously
Welding is connected.
Preferably, the sealing ring is arranged at intervals multiple, and ensures that both ends are at least at sensor frame and steel plate ring cooperation
One is set respectively.
Protection scope of the present invention is not limited to the above embodiments, it is clear that those skilled in the art can be to this hair
It is bright to carry out various changes and deformation without departing from scope and spirit of the present invention.If these changes and deformation belong to power of the present invention
In the range of profit requirement and its equivalent technologies, then including the intent of the present invention is also changed and deformed comprising these.
