Abstract
The utility model discloses a kind of water sealing structure for push pipe starting well hole, it is characterized in that, including the armored concrete sealing door opening being fixed on the starting well borehole wall, the outer face of described armored concrete sealing door opening is connected with ring-shaped rubber plate, the inner headed face of described ring-shaped rubber plate is sealed on pipeline periphery, described armored concrete sealing door opening and described ring-shaped rubber plate are arranged concentrically with starting well hole, and the diameter of described armored concrete sealing door opening is more than starting well hole diameter.This utility model can effectively prevent subsoil water and silt from pouring in starting well, it is ensured that pipeline jacking direction soil stabilization, does not caves in, it is ensured that construction safety；Can construct at multiple work surfaces as required, speed of application is fast simultaneously；Size, flexibility and reliability can be adjusted according to jacking pipe diameter；Technique is simple, it is simple to processing and make, construction cost is low.
Description
Technical field
This utility model relates to a kind of water sealing structure, particularly relates to a kind of water sealing structure for push pipe starting well hole.
Background technology
During push pipe, necessarily having gap between pipeline and hole, closing must be carried out in gap, such as bad sealing,
The outer subsoil water of well and silt will flow in active well from this gap, affect operation in well, even cause the hole soil body to collapse
Collapse, have an accident.At present, hole sealing generally uses packing.But packing sealing cost is high, processing and fabricating is complicated, adds
Between man-hour long, construction benefit and economic benefit are poor.
Utility model content
This utility model provide for solving technical problem present in known technology a kind of for push pipe starting well hole only
Water-bound, this water sealing structure simple in construction, easy to make, low cost.
This utility model is adopted the technical scheme that by solving technical problem present in known technology: a kind of be used for push pipe
The water sealing structure at starting well hole, including the armored concrete sealing door opening being fixed on the starting well borehole wall, at described reinforcing bar
Being connected with ring-shaped rubber plate on the outer face of concrete sealing door opening, the inner headed face of described ring-shaped rubber plate is sealed in outside pipeline
On disc, described armored concrete sealing door opening and described ring-shaped rubber plate are arranged concentrically with starting well hole, described reinforcing bar
The diameter of concrete sealing door opening is more than starting well hole diameter.
Described ring-shaped rubber plate uses screw bolt and nut to be fixed on described armored concrete sealing door opening, described bolt embedment
On described armored concrete sealing door opening, between described nut and described ring-shaped rubber plate, it is provided with keeper plate of steel.
The internal diameter 10cm less than outer diameter tube of described ring-shaped rubber plate.
A diameter of outer diameter tube of described armored concrete sealing door opening adds 8～10cm.
This utility model has the advantage that with good effect: uses and fixes armored concrete sealing door opening on the borehole wall,
Affixed ring-shaped rubber plate on the outer face of door opening, uses the gap between ring-shaped rubber plate closed conduct and hole, it is possible to have
Effect prevents subsoil water and silt from pouring in starting well, it is ensured that pipeline jacking direction soil stabilization, does not caves in, it is ensured that construction safety；
Can construct at multiple work surfaces as required, speed of application is fast simultaneously；Size can be adjusted, flexibly according to jacking pipe diameter
Reliably；Technique is simple, it is simple to processing and make, construction cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, armored concrete sealing door opening, 2, bolt, 3, nut, 4, ring-shaped rubber plate, 5, steel pressure
Plate.
Detailed description of the invention
For summary of the invention of the present utility model, feature and effect can be further appreciated that, hereby enumerate following example, and coordinate
Accompanying drawing describes in detail as follows:
Referring to Fig. 1, a kind of water sealing structure for push pipe starting well hole, including the reinforcing bar being fixed on the starting well borehole wall
Concrete sealing door opening 1, is connected with ring-shaped rubber plate 4 on the outer face of described armored concrete sealing door opening 1, described
The inner headed face of ring-shaped rubber plate 4 is sealed on pipeline periphery, described armored concrete sealing door opening 1 and described annular rubber
Offset plate 4 is arranged concentrically with starting well hole, and the diameter of described armored concrete sealing door opening 1 is more than starting well hole diameter.
In the present embodiment, described ring-shaped rubber plate 4 uses bolt 2 and nut 3 to be fixed in described armored concrete sealing
On door opening 1, described bolt 2 is embedded on described armored concrete sealing door opening 1, in described nut 3 and described annular
Keeper plate of steel 5 it is provided with between rubber slab 4.The internal diameter 10cm less than outer diameter tube of described ring-shaped rubber plate 4.Described reinforcing bar mixes
A diameter of outer diameter tube of solidifying soil sealing door opening 1 adds 8～10cm.
Although preferred embodiment of the present utility model being described above in conjunction with accompanying drawing, but this utility model not office
Being limited to above-mentioned detailed description of the invention, above-mentioned detailed description of the invention is only schematically, is not restrictive, this
The those of ordinary skill in field, under enlightenment of the present utility model, is being protected without departing from this utility model objective and claim
Under the ambit protected, it is also possible to make a lot of form, within these belong to protection domain of the present utility model.
