Description
Technical field
The present invention relates 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 present invention is intended to provide a kind of can be commonly used for all kinds of stratum, only high hydraulic pressure, the good push-bench disengaging of slurry sealing effectiveness
Hole sealing device.
The content of the invention
The purpose of the present invention 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 capsule
Body, 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 sealing
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.
