The invention discloses shield tunneling sediment improvement agent injection devices, are related to medium conveying apparatus technical field.The present invention includes spray head, spout ring, middle supporting plate, elastic packing plate, pressure ring week, side was fixed with raceway, the nozzle mechanism matched with upper raceway is provided at the top of upper raceway, the bottom of nozzle mechanism has been screwed connection ring, and connection ring is screwed the lower raceway matched with upper raceway.The use that the present invention passes through nozzle mechanism; modifying agent is uniformly ejected in the dregs around nozzle mechanism by spout; and dregs around is stirred and is crushed by cross scraper plate and protection knife; so that modifying agent mixes more evenly with dregs, the problem of avoiding cutterhead mud lining, screw machine package；Spray head ring cap can stop dregs to directly act on spout rubber, and rubber excessive wear is avoided to cause seal failure, or lead to the appearance of rubber seal screen resilience deficiency situation since dregs is more.
Description
Technical field
The invention belongs to medium conveying apparatus technical fields, are injected and are filled with sediment improvement agent more particularly to shield tunneling
It sets.
Background technique
Shield machine is the large scale equipment for carrying out constructing tunnel, and shield machine is the steel component of a cylindrical body, is using shield
When machine is constructed, shield machine cuts the soil body while to being pushed forward along tunnel axis, and shell, that is, shield of shield machine, shield is to shield
The also unlined Tunnel section that structure machine-cut is cut out plays a part of temporary support, and cutting, casting and the lining cutting of shield machine exist
It is carried out under the shielding of shield.
In shield machine with soil pressure balance for construction, it is often necessary to which the soil body injects sediment improvement agent, by shield machine front
Sediment improvement agent is transported to cutterhead by heart swivel joint, after preventing dregs from entering shield machine Tu Cang, cause cutterhead mud lining,
The problem of screw machine wraps up occurs.
But it is found in practice of construction, sediment improvement agent is only transported to by knife by the centre revolving joint of shield machine front
Disk to the soil body inject sediment improvement agent, can not to sediment improvement in place, can still cause cutterhead mud lining, screw machine package ask
Topic occurs；And existing sediment improvement agent spout rubber seal screen resilience is insufficient, and easy to wear in dregs or tearing causes close
Envelope failure, causes sediment improvement agent spout to block.
Summary of the invention
