Description
Technical field
The invention belongs to technical field of building construction, are exactly specifically to be related to a kind of pipe-jacking with large diameter stopping device.
Background technology
As urbanization is fast-developing on a large scale, a large amount of underground pipings, underground traffic, hypogee be able to it is constantly newly-built,
Reconstruction and enlarging, have emerged in large numbers a variety of Underground Construction technologies, and wherein push bench process is applicable in that soil body range is wide, soil layer is disturbed with it
The advantages that small, job engineering amount is lacked is widely used.Especially this several years, pipe-jacking technology tended to ripe, push pipe in big or middle city
It constructs and develops to major diameter, great burying, big scale of construction direction.
Often cause jack retraction because of addition top iron or tube coupling in jacking construction, push pipe stops jacking, at this time along axis
Direction bears to retreat frictional resistance force effect between push-bench front end soil body active earth pressure and pipe shaft and the soil body, generates tube coupling and retreats thing
Therefore.Under unfavorable geological condition, when pipe-jacking with large diameter stops jacking, push-bench and tube coupling are reversed and often cause soil layer before pipe
It stays, or even ground large area is caused to settle, seriously affect the safety of ground buildings or structures.
Chinese patent 201410382504.4 discloses a kind of jacking pipe joints stopping device, including rack, is pushed up after being set to
Between jack and the tube coupling for waiting for jacking, the tube coupling both sides for waiting for jacking are respectively equipped with the first connector, and the rack is in institute
It states and waits for that the tube coupling both sides of jacking are respectively equipped with a reaction frame, the reaction frame is equipped with corresponding with the first connector second and connects
Fitting.The technology is cooperated by the second connector on the first connector and reaction frame that tube coupling both sides are arranged, by
Counter force system on reaction frame prevents the retrogressing for retreating push pipe head and tube coupling in channel after jack is retracted from avoiding the earthwork
The generation of cave-in accident, but the device is complicated for operation to be needed to stop other construction operations can just to complete, and affects construction effect
Rate.
