Description
Technical field
It the utility model is related to engineering machinery field, and in particular to a kind of push-bench export ＆ import sealing device.
Background technology
In recent years, push-bench is widely applied in Urban Buried Pipeline Network construction.And in real work, push-bench
Originate and receive process in, an annular gap is often formed between push-bench and the soil body, if dealing with improperly, may be drawn
The problems such as sending out stratum settlement, construction pipe deforming, and then have a strong impact on construction quality, it is therefore desirable to certain stop is taken at hole
Starch seal approach.
In current work progress, it will usually using targeted design water-seal pile and installation watertight rubber cord by the way of come
Solve the above problems, sealing pile driving construction generally requires to expend substantial amounts of human and material resources cost, and each requirement of engineering is for applying
Work environment particular design, without universality.And the water-stagnating effect of sealing cord, maintainability and service life are all undesirable.
The utility model, which aims to provide, a kind of can be commonly used for all kinds of stratum, only high hydraulic pressure, the good push-bench of slurry sealing effectiveness
Export ＆ import sealing device.
Utility model content
The purpose of this utility model is achieved through the following technical solutions：
A kind of push-bench export ＆ import sealing device, including hole ring beam and co-axial sealing steel ring and elastic packing
Utricule, the sealing steel ring is arranged at hole ring beam side, and its internal diameter is not less than hole ring beam；The sealing utricule is located at close
Seal on the inside of steel loop.
Further, the quantity of the sealing utricule is no less than two, and is set on the sealing steel ring between adjacent utricule
There is Grouting Pipe.
Further, it is to be detachably connected or be fastenedly connected between the elastic packing capsule and sealing steel ring.
Further, fixed and supported by flanged plate between the sealing steel ring and hole ring beam.
Further, the elastic packing utricule is provided with fluid charge and discharge mouth and is used for elastic sack body internal fill fluid.
Further, flow control valve is provided with the fluid charge and discharge mouth to be used to control elastic fluid loading.
Brief description of the drawings
Fig. 1 is the structural representation of sealing device when push-bench enters hole.
Fig. 2 is the partial enlarged drawing at A in Fig. 1.
Fig. 3 is that push-bench enters the schematic diagram at A during hole.
Fig. 4 is the structural representation that push-bench is appeared with sealing device.
Embodiment
Embodiment 1：

Hole ring beam 1；The elastic packing utricule 3 is on the inside of sealing steel ring.The elastic packing utricule is provided with fluid charge and discharge mouth
It is used to control elastic fluid loading for being provided with flow control valve to elastic sack body internal fill fluid, at fluid charge and discharge mouth.
Further, the elastic packing utricule 3 includes utricule 31 and utricule 32, and sealing steel ring between the two is provided with
Grouting Pipe 4.
Further, it is to be detachably connected or be fastenedly connected between the elastic packing capsule 3 and sealing steel ring 2.
Further, fixed and supported by flanged plate 5 between the sealing steel ring 2 and hole ring beam 1.
Embodiment 2：
The present embodiment provides a kind of method for originating push-bench using the described device of embodiment 1, comprises the following steps：
First, above-mentioned sealing device is arranged at the collar tie beam of hole；
Second, when passing through sealing device before push-bench enters hole, elastic packing utricule 31 and 32 is not filled with fluid, is shrivelled
State, in case push-bench squeezes bad air bag when moving forward；
3rd, when push-bench will enter hole, fluid is filled into elastic packing utricule 31 and 32, is at full shape
State；
4th, open Grouting Pipe 4 and remain its opening, soil body space is filled with slurries, ensure excavation surface soil
Gushed outside body and underground water；
5th, push-bench remains that elastic packing utricule 31 and 32 is full state during entering hole, keeps Grouting Pipe 4
Opening until push-bench completely into.
Embodiment 3：
The present embodiment provides a kind of push-bench and appeared with sealing device, as shown in figure 4, its general principle and the phase of embodiment 1
Together, difference is that the sealing device is located at the soil body rear end when push-bench is appeared.End is provided with the outside of sealing steel ring simultaneously
Head capping 6, and it is provided with draining valve 7 in termination capping 6.
Embodiment 4：
The present embodiment provides a kind of method that push-bench is received using the described device of embodiment 3.Comprise the following steps：
First, the sealing device is fixed at the collar tie beam of hole；
Second, when push-bench passes through elastic sealing device, elastic packing utricule 3 is not filled with fluid, is shrivelled state, avoids
Shield machine squeezes bad elastic packing utricule 3 when moving forward；
3rd, after push-bench passes through elastic packing utricule 3, fluid in utricule is discharged, Grouting Pipe is opened and remains slurries
Injection, soil body space is filled with slurries, ensure to gush outside the excavation surface soil body and underground water；
4th, open the water in the exclusion sealing device of draining valve 7；
5th, water in sealing device all after emptying, opens sealing device termination capping 6；
6th, when push-bench is appeared, it is full state to remain elastic sack body 3, opens Grouting Pipe and remains slurries
Injection, soil body space is filled with slurries, ensure to gush outside the excavation surface soil body and underground water, until push-bench receives.
