Leakproofness further increases waterproof performance.
Preferably, on the segment ontology positioned at the channel wherein one end end face and segment body peripheral anchor ring up to
Several hanging rings are respectively equipped on few side side.
By using above-mentioned technical proposal, since channel cross-section is larger, in order to facilitate pouring for segment ontology, generally use
Wet vertical moulding process, pours channel segment positioned at vertical direction, in this way, in installation process, by the side of two sides
90 ° of segment ontology overturnings are realized in mutual cooperation between hanging ring, when in segment, ontology is transported to job location, are needed segment
Ontology, which from its channel is located at vertical position and overturns to its channel, to be horizontally situated, at this time by simultaneously in the anchor ring of segment ontology
And exert a force on end face normal thereto, the power acted on the hanging ring of side is lifting force, segment ontology is lifted to and is realized overturning,
The power acted on channel end surface upper lift ring is auxiliary force, so that segment ontology is kept balance during overturning, prevents from colliding with,
To improve speed of application and ensure that this weight of segment is not damaged.
Preferably, the hanging ring is pre-buried is arranged in the intrinsic hanging ring in segment.
By using above-mentioned technical proposal, in carrying out casting process, by the pre-buried setting of hanging ring, so that hanging ring and segment sheet
Connection between body is even closer, avoids during applying pulling force to hanging ring, since this body weight of segment causes greatly very much to save
Separated between Duan Benti and hanging ring, cause the accident there is a situation where.
Preferably, the hanging ring at least three on the channel wherein one end end face, and be located in the channel end surface
The central point of geometric figure of the connected formation of hanging ring be located on channel center's axis.
It by using above-mentioned technical proposal, is limited by the quantity to hanging ring, so that hanging on end face is used alone
It when ring, can guarantee the stability of segment ontology, avoid the shaking in the ontology hoisting process of segment.
Preferably, quantity of the hanging ring on same side positioned at the segment body peripheral anchor ring side be zero or
At least three, the central point and the side center side point of the geometric figure of the connected formation of hanging ring on the side equipped with hanging ring
It is overlapped setting.
By using above-mentioned technical proposal, limited by the quantity to the hanging ring being arranged in circumferential lateral surface, so that
The stability that can guarantee ontology lifting in segment when lift to side upper lift ring, guarantees the safety of hoisting process
Property.
In conclusion the utility model has the following beneficial effects:
