Description
Technical field
The invention belongs to no-dig technique underground engineering field, the rectangular top tube top iron for being related to retract is to be used for high efficiency push pipe
The auxiliary construction technology of jacking.
Background technology
Rectangular top pipe as a kind of important trenchless technology be widely used in Urban Underground Passage, subway entrance,
The underground engineering constructions such as pipe gallery field, since its excavation area is small, overall cost is low, construction efficiency is high, rectangular cross section is sharp
With the high advantage of rate, there is vast potential for future development in urban underground engineering construction field.
But since rectangular top pipe jacking construction is that each section of prefabricated tube coupling one saves land jacking forward, on the fixed top in rear end
Into oil cylinder per one stroke of jacking forward after, it is necessary to retract oil cylinder, and bulky rectangular top iron and U-shaped is sling and transferred again with crane
Iron is pushed up, is provided for next section section of jurisdiction and places space.This will occupy a large amount of construction time, reduce jacking construction efficiency, cause
Construction cost increases.
Invention content
The purpose of the present invention is to provide a kind of rectangular top tube top iron construction to retract and application methods；It avoids existing
Rectangular top pipe engineering construction every section tube top into after, repeatedly lifting and lower caving iron will waste a large amount of construction time.
And the top iron construction that can be retracted considers rectangular top iron, U-shaped top iron and jacking oil cylinder to be connected as entirety, whole rollback rectangular top
Iron, U-shaped top iron and jacking oil cylinder, to improve construction efficiency.
To achieve the above object, a kind of rectangular top tube top iron construction to retract is designed, which is characterized in that by iron block 1, square
Shape top iron 2, U-shaped top iron 3, the jacking oil cylinder 4 with spherical hinge and guide rail 10 form, the end face of rectangular top iron 2 and U-shaped top iron 3
It is welded as entirety using several iron blocks 1, the other end of U-shaped top iron 3 is connected as entirety using bolt 8 with jacking oil cylinder 4, realizes
Rectangular top iron 2, U-shaped top iron 3 and 4 three of jacking oil cylinder linkage, are connected as rectangular top iron 2 and U-shaped top iron 3 on ground whole
Body lifts on the guide rail 10 of active well 6；In rollback jacking oil cylinder 4, rectangular top iron 2 and the whole edge of U-shaped top iron 3 is driven to lead
Rail 10 retracts.
Lifting jacking oil cylinder 4 and cylinder rack 5 are placed in 7 front end of rear parados.
Jacking oil cylinder 4 needs rollback oil cylinder vacating space to place next section section of jurisdiction when jacking reaches a stroke forward
9。
Welding position of the iron block 1 on two top iron is each two of top iron both sides welding, welding two above iron is pushed up, if top
Iron weight is little, and rectangular top iron 2 and U-shaped top iron 3 can be used and directly carries out spot welding company within each one week in contact interface outer ring and inner ring
The mode connect.
U-shaped top iron 3 is connect using direct welding manner in active well 6 with jacking oil cylinder 4 or bolt 8 connects, 8 specification of bolt
For Φ 20,4 end of jacking oil cylinder is arranged symmetrically 4 bolts 8 up and down.
The end of jacking oil cylinder 4 is a spherical hinge, ensures that there are certain degree of freedom at this in rollback oil cylinder；With it is U-shaped
It pushes up the jacking oil cylinder 4 that iron 3 connects to ensure to arrange with jacking axis longitudinal direction vertical guide symmetry principle, and is arranged since least significant end；
When rectangular top iron is smaller with U-shaped top iron weight, it respectively can arrange one on jacking axis longitudinal direction vertical guide both sides and be connect with U-shaped top iron
Jacking oil cylinder, when rectangular top iron and U-shaped top iron weight are larger, can jacking axis longitudinal direction vertical guide both sides respectively arrangement two and
The jacking oil cylinder of U-shaped top iron connection.
The rectangular top tube top iron construction application method that can be retracted, lifting jacking oil cylinder 4 and cylinder rack 5 are placed in rear parados 7
Front end.Rectangular top iron 2 and U-shaped top iron 3 are connected as entirety on ground, lifted on the guide rail 10 of active well 6.U-shaped top iron with
Band spherical hinge jacking oil cylinder 4 uses bolt 8 to connect, and jacking cylinder movement drives rectangular top iron 2 and the whole front and back shifting of U-shaped top iron 3
It is dynamic, to realize the rectangular top tube top iron construction that can be retracted.
Underground engineering construction is carried out in city, surrounding traffic and trip will unavoidably be impacted, so underground
Engineering construction is very high to construction period, and the reduction of duration will directly or indirectly reduce the cost of engineering.Existing rectangular top pipe
Engineering construction every section tube top into after, lift by crane rectangular top iron and U-shaped top iron, rollback jacking oil cylinder, for next section tube coupling
Transfer vacating space.Lifting and lower caving iron will waste a large amount of construction time repeatedly, the construction period be increased, to improve
Construction cost.And the top iron construction that can be retracted considers rectangular top iron, U-shaped top iron and jacking oil cylinder to be connected as entirety, reduces every
Secondary lifting and two class top iron the time it takes of decentralization.
Compared with prior art, the present invention mainly there is following advantage：
1. construction efficiency is high.It has saved each lifting and has transferred bulky rectangular top iron and U-shaped top iron the time it takes, to
Improve construction efficiency.
2. simple in structure.Only with simple iron block and the modes such as it is bolted and makes rectangular top iron, U-shaped top iron and jacking
Oil cylinder forms an entirety, so the structure and construction method are simple.
3. cost-effective.The labor and time cost that furred ceiling iron is spent has been reduced, efficiency is improved, to be construction
Unit and society reduce cost.
4. wide adaptability.Suitable for rectangular top pipe jacking construction under all operating modes.
