Bolt hole B is bolted to connection between adjacent well piece；Connection reinforcing bar, vertically-adjacent each segment are equipped with U-shaped groove well on piece
By connection reinforcing bar through constraint slurry anchor connection technology connection.
Wherein, the effect that adjacent well piece is bolted to connection is to ensure that 4 pieces of well pieces can sink simultaneously, without
The effect that the bolt hole B of U-shaped groove well piece corresponding position does not penetrate well piece is to ensure that the water outside open caisson does not enter in open caisson.
Constraint slurry anchor connection technology: the technology is to carry out grouting anchoring after two connection reinforcing bars to be pulled open to certain distance to realize that reinforcing bar can
By the mode of connection.It is simple to constrain slurry anchor connection technique building technology, it is low in cost, it has also become the member reinforcing steel bars such as precast shear wall
One of longitudinally connected major way.
Preferably, waterproof layer is equipped with U-shaped groove well piece and without U-shaped groove well piece stitching portion.
Preferably, it is equipped with blade foot below the well piece of a nethermost segment, opens up groove on the inside of the borehole wall above blade foot.It should
The effect of design be to make to have between bottom concrete and bottom plate and the borehole wall it is better be coupled, to transmit Foundation pressure.
Preferably, the aperture connecting with sewage conduct is opened up without U-shaped groove well on piece.
Preferably, the outside of the U-shaped groove with U-shaped groove well piece is equipped with gas vent and grout hole.After lifting, toward filling
It starches in hole and is in the milk, slurry is flowed out from gas vent, and the slurry to ensure duct is full.
Preferably, the height of each segment is 2~3m.
Preferably, the material of the well piece is armored concrete.
Preferably, the waterproof layer is waterproof roll.
The utility model has the advantages that (1) prefabricated assembled open caisson described in the utility model can significantly shorten the duration that open caisson is built on-site,
Substantially accelerate the construction speed of pipe-jacking project；(2) the prefabricated assembled open caisson assembled in situ is easy, to ambient enviroment when construction
It influences smaller；(3) the prefabricated assembled open caisson entirety good stress performance, structural stability are high；(4) the prefabricated assembled open caisson
Convenient for the production of batch production, normalized design.
