Description
Technical field
This utility model relates to construction technical field of auxiliary equipment, especially a kind of for mud jacking mouth space
By madjack pipe attachment means in limited time.
Background technology
During cast-in-situ box girder construction by stages, when its second stage uses prestressing force adapter air inlet prestressing force to connect,
Generally there is the problem of limited separation between prestressing force adapter and anchor plate, existing way is at anchor plate
Installing short steel pipes and mud jacking flexible pipe between mud jacking mouth and prestressing force adapter, interference is passed through at the two ends of mud jacking flexible pipe
Engagement sleeves is located on anchor plate and prestressing force adapter, and this connected mode is shorter soft with mud jacking due to short steel pipes
Pipe cannot firmly connect, and easily comes off when mud jacking stress, and cannot be timely during closure mud jacking mouth after mud jacking
Taking off mud jacking flexible pipe, the waiting time is long, can not take off mud jacking flexible pipe immediately and carry out mud jacking mouth closure after mud jacking,
Have a strong impact on the squeezing quality watering box beam.
Utility model content
The technical problems to be solved in the utility model is: in order to solve cast-in-situ box girder construction by stages in existing skill
Time due to limited separation between prestressing force adapter and anchor plate, use short steel pipes to coordinate mud jacking flexible pipe to answer in advance
The mode that power connector is connected with anchor plate, when causing mud jacking stress, mud jacking flexible pipe holds caducous problem, existing
Thering is provided a kind of madjack pipe attachment means when mud jacking mouth limited space, this attachment means is not limited by a space,
It is firm to connect, convenient disassembly.
This utility model solves its technical problem and be the technical scheme is that one is subject to for mud jacking mouth space
Madjack pipe attachment means in limited time, this attachment means includes adapter, the first connecting tube and the second connecting tube,
Offer inner chamber in described adapter, the two sides that described adapter is adjacent offers respectively the first connecting hole and
Second connecting hole, described first connecting hole and the second connecting hole all with described inner space, described first connect
Pipe is threadeded with described first connecting hole, and described second connecting tube is threadeded with described second connecting hole.
In this programme, the first connecting tube is connected by adapter with the second connecting tube, and it is adjacent to be arranged on adapter
Two sides on, it is achieved that turning to of access path, effective solve between prestressing force adapter and anchor plate
During limited separation, it is impossible to the problem being reliably connected, the first connecting tube and the second connecting tube all with adapter screw thread
Connect, it is achieved that while easy to loading and unloading, adapter can rotate relative to the first connecting tube, not by anchor plate and
The restriction that between adapter, space is little, due to this attachment means convenient disassembly, therefore after mud jacking terminates, can
Quickly dismantled, then mud jacking mouth is blocked, indirectly improve squeezing quality.
For the ease of controlling whether when mud jacking to carry out mud jacking and the regulation of mud jacking uninterrupted, further, institute
State and be in series with ball valve in the second connecting tube.
For the ease of the convenience of handling, further, between two ends and described second connecting tube of described ball valve
Use threaded.
Preferably, described ball valve is single piece type ball valve.
Preferably, the material of described adapter is steel.
Preferably, the material of described first connecting tube is steel.
Preferably, the material of described first connecting tube is steel.
Preferably, described first connecting tube is vertical with the second connecting tube.
The beneficial effects of the utility model are: the madjack pipe when mud jacking mouth limited space of the present utility model
Attachment means is cleverly by setting up adapter between the first connecting tube and the second connecting tube, it is achieved prestressing force
The turning to of access path between adapter and anchor plate, adapter can relative first connecting tube freely rotatable, no
Limited by space between anchor plate and adapter is little, effectively solve prestressing force adapter and anchor plate it
Between the problem of limited separation, and easy to loading and unloading, simple and practical, equipment can be reused, and shortening is executed
In the work cycle, improve squeezing quality.
