It slips contrary.In this way, when box beam 1 will occur smooth, after traction rope 5 is exceptionally straight just to the reversed tractive force of box beam 1
The smooth trend that box beam 1 can be offset, without being displaced sideways box beam 1.
Embodiment 7
The embodiment of the present invention proposes a kind of pushing tow Anti-slip construction method, comprising: step 001: building predetermined quantity
Pushing tow Temporary Piers 2 and reverse drawing bracket 6, make reverse drawing bracket 6 align with pushing tow Temporary Piers 2, at the top of each pushing tow Temporary Piers 2
Walking jack 3 is installed, guarantees that the pushing tow direction of walking jack 3 is consistent, by mechanical analysis, determines the cunning of box beam 1
Direction is slipped, reverse drawing bracket 6 is arranged in the opposite direction in the smooth direction of the box beam 1；Step 002: before pouring box beam 1,
Pre-embedded bolt is connected at the top of the bar construction of box beam 1, after the completion of box beam 1 is poured, makes pre-embedded bolt from the top of box beam 1
Expose, traction device 4 is connected on pre-embedded bolt, traction device 4 uses hoist engine；It is built simultaneously in the front-end and back-end of box beam 1

The support of walking jack 3 on pier 2, being capable of the smooth transition between adjacent pushing tow Temporary Piers 2；Step 003: by box beam
1 and nose girder 101 be placed on the walking jack 3 at least two pushing tow Temporary Piers 2, by one end of traction rope 5 and elevator
Machine is connected, and the other end is connected with reverse drawing bracket 6, and traction rope 5 uses wirerope；Step 004: pushing tow is being carried out to box beam 1
When, hoist engine is controlled in advance by wirerope and loosens a segment length, then is controlled walking jack 3 and pushed the movement of box beam 1 mutually isometric
The distance of degree, wirerope is opposite at this time tightens, if box beam 1 will occur smooth on walking jack 3, wirerope can be held
Begin to bear the reversal interlocking relay to box beam 1, and be tauted, prevents box beam 1 from occurring smooth, staff can tightening by wirerope
State judges that smooth situation may occur between box beam 1 and walking jack 3.Before pushing box beam 1 every time, all pass through volume
The machine of raising loosens one segment length of wirerope, then pushes box beam 1 to move forward by walking jack, so repeats, until will
Box beam 1 is sent to predetermined position.
In step 003, keep traction rope 5 parallel with the pushing direction of box beam 1 after tightening, such box beam 1 is to stride
The pressure of formula jack 3 would not be pulled the influence of rope 5.
In step 004, length that traction rope 5 loosens every time and walking jack 3 drive every time box beam 1 it is mobile away from
From equal in magnitude, it is smooth can thus to guarantee that box beam 1 will not occur between walking jack 3, while will not occur
Walking jack 3 pushes the situation not in place of box beam 1.
