Description
Technical field
The present invention relates to a kind of transportation system and construction method, particularly relate to transportation system and the construction method utilized during a kind of reverse construction.
Background technology
In recent years, along with city old shopping centre is transformed, increasing deep-foundation pit engineering occurs in the bustling location that surrounding enviroment are complicated, foundation pit construction is caused to be frequently subjected to extraneous factor impact, such as periphery high level basis, subway etc., for ensureing surrounding building in work progress, the stablizing of structure and limited by the field, contrary sequence method is widely used in the middle of engineering support form.
In reverse construction, when upper strata xoncrete structure is closed, it is impossible to use Large-scale Hoisting equipment, tradition lifting disassembled for transport system to waste time and energy.
Summary of the invention
In order to overcome the deficiency of above-mentioned situation, present invention aim at providing heavy component transportation system after a kind of contrary sequence method dismounting.Including fixing guide rail, described fixing guide rail connects chain block by pulley, and described pulley is also associated with traction apparatus.
Described fixing guide rail is H profile steel, and described pulley is connected to the lower flange of H profile steel.
Described traction apparatus is hoist engine.
Described pulley and chain block are multiple and are arranged in below fixing guide rail.
Described traction apparatus connects the pulley nearest away from described traction apparatus.
A kind of construction method, comprises the steps:
Step one: decline preparation: first set up support on reinforced concrete floor, group hoist it is fixedly installed on support, then perforate on the reinforced concrete floor under group's hoist, the lower end hook portion of group's hoist connects lifting rope and enters lower layer space through reinforced concrete floor, and lifting rope lower end takes interim fixation to connect heavy component.
Step 2: entire lowering: after heavy component dismounting, operating group's hoist, each suspension centre calabash remains a constant speed declines, and often declines 100mm, can arrange level monitoring point on hoist lifting hook and adjust each suspension centre level, and whether inspection entire lowering balances in time.
Step 3: change calabash and connect: after heavy component entire lowering to fixed pan, remove the interim fixation of group's hoist, reconnecting the chain block in heavy component transportation system after the contrary sequence method described in right 1 to 5 is dismantled, post-tensioning moves chain block, makes heavy component unsettled.
Step 4: transport: use traction apparatus to pull pulley, by fixing guide rail, heavy component is transported to material hoisting port.
The invention has the beneficial effects as follows: this system and construction method can not have the inside configuration of hanging device, transport heavy component, save trouble and labor.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only some embodiments of the present invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is transportation system structure schematic diagram of the present invention；
Fig. 2 is the schematic diagram readily appreciating step one and step 2 in construction method of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Refer to Fig. 1, a kind of induction system, inside have fixing guide rail 1, described fixing guide rail 1 to be preferably the H type shaped steel of welding, use Q345B level.Described fixing guide rail 1 is fixed on superstructure beam by lifting rope.The lower flange of described H type shaped steel is snapped with pulley 1, preferably several pulley 2, and each pulley 2 connects 1 chain block 3, and the hook end of chain block 3 connects heavy component 5 by lifting rope.This system also includes traction apparatus 4, preferably a hoist engine.Hoist engine, according to practice of construction needs, can connect multiple pulley by serving, it is preferred that according to nearby principle, hoist engine is connected apart from its nearest pulley by serving.
A kind of construction method, comprises the steps:
Step one: decline preparation: first set up support 7 on reinforced concrete floor 6, group hoist 8 it is fixedly installed on support 7, then perforate on the reinforced concrete floor 6 under group's hoist 8, the lower end hook portion of group's hoist 8 connects lifting rope and enters lower layer space through reinforced concrete floor 6, lifting rope lower end takes interim fixation to connect heavy component 5, connect into entirety, it is to avoid heavy component 5 sliding comes off.Described support 7 includes the support support that be connected fixing with reinforced concrete floor 6 and is placed in the crossbeam supported on support.
Step 2: entire lowering: after heavy component 5 dismounting, operating group's hoist 8, each suspension centre calabash 8 remains a constant speed declines, and often declines 100mm, can arrange level monitoring point on calabash 8 suspension hook and adjust each suspension centre level, and whether inspection entire lowering balances in time.Entire lowering, security protection is the difficult point that scheme is implemented.Whole step-down operation process, personnel are positioned at reinforced concrete floor 6 top, it can be ensured that operator safety.
Step 3: change calabash and connect: after heavy component entire lowering to fixed pan, remove the interim fixation of group's hoist 8, reconnect the chain block 3 in heavy component transportation system after the contrary sequence method described in right 1 to 5 is dismantled, post-tensioning moves chain block 3, make heavy component 5 unsettled, it is ensured that gravity balance system stability.
Step 4: transport: use traction apparatus 4 to pull pulley 2, drags pulley 2 and moves on fixing guide rail 1, thus band movable pulley 2, chain block 3 and heavy component 5 to material hoisting port, unload heavy component 5.
The invention has the beneficial effects as follows: this system can not have the inside configuration of hanging device, transport heavy component, save trouble and labor.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
