Abstract
The invention discloses a semi-mechanized steel strand laying method for a circular silo. The method comprises following steps: S1, refitting and reinforcing a slip-form platform frame; S2, installing winches; S3, installing cylinder wall steel strand fixing frames and performing alignment; S4, making steel wire ropes on the winches pre-pass through the steel strand fixing frames; S5, connecting the steel strands and the steel wire ropes; S6, retracting the steel wire ropes through the winches, manually making the steel strands be in place through a fine tuning manner, disconnecting the steel wire ropes and the steel strands, and fastening the steel strands and the steel strand fixing frames through fastening wires. By employing the laying method, the steel strands can be laid in a semi-mechanized manner through the winches, problems that the labor intensity of steel strand laying workers is large and the laying progress is slow during the slip-form construction are solved, the selected devices are economical and reasonable, the construction cost is reduced, and the operation time is saved.
Description
Technical field
The present invention relates to steel strand and lay field, specifically relate to a kind of semi-mechanization steel strand laying method for round silo.
Background technology
At present, steel strand construction generally adopts artificial laying in the industry, and when steel strand are laid, front needs a people to adjust steel strand and wears direction, and rear personnel hold steel strand pushed forward with hand-tight.This construction method not only labor intensive, for 30m diameter silo, per tour steel strand are laid at least needs 12 workmans not stop operation; And be difficult to when large silo of constructing, steel strand are arranged intensive ensure that steel strand laying progress meets the construction speed of barrel, often occur to lay because of steel strand to occur the situations such as the work holdup not in time.And adopt semimechanized laying laying method, the labour intensity of operating personnel can be greatly reduced, improve the laying efficiency of steel strand; And utilize semi-automatic steel strand laying apparatus, decrease operating personnel, reduce the load of slip form platform during silo construction, improve the safety of slip form platform, the risk that reduction accident greatly occurs.
Summary of the invention
For the technical problem existed in prior art, the object of the present invention is to provide a kind of semi-mechanization steel strand laying method for round silo.
To achieve these goals, the technical solution adopted in the present invention is: a kind of semi-mechanization steel strand laying method for round silo, comprises the following steps:
S1, slip form platform support body are reequiped:
In the some steel strand tip position near barrel place, selected hoist engine installation site, carries out repacking to the slip form platform support body of installation site and reinforces;
S2, hoist engine are installed:
Slip form platform support body after repacking is reinforced installs hoist engine, and the stability of hoist engine must meet the dilatory work of follow-up steel strand;
S3, barrel steel strand fixed mount are installed, centering:
First steel strand on the estimation need the track laid to install some steel strand fixed mounts, and utilize steel strand fixed mount to replace the vertical distributing bar of part barrel;
Wearing in advance of S4, steel wire rope of windlass:
By the steel strand fixed mount of the cable wire end on hoist engine through round silo, until steel strand tip position;
The connection of S5, steel strand and wire rope:
Utilize steel cable clamp, by parallel with steel strand termination for cable wire end connection, the rubber pad that buckle and steel strand contact position pad prevent steel strand in pulling to be damaged;
S6, regain wire rope with hoist engine, artificial fine setting is in place to steel strand, unties the connection between wire rope and steel strand, steel strand and steel strand fixed mount tied silk is tightened.
Beneficial effect of the present invention shows:
The laying method that the present invention proposes utilizes hoist engine to achieve the object of semi-mechanization laying steel strand, solve the steel strand when slding form operation and lay the problem that operating personnel consumes greatly, progress is slow, the device economical rationality of selecting, reduces construction cost, has saved operation holding time.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of step S4.
Fig. 2 is the schematic diagram of step S5.
Detailed description of the invention
For further describing the present invention, below in conjunction with embodiment, it is described further.
For a semi-mechanization steel strand laying method for round silo, comprise the following steps:
S1, slip form platform support body 1 are reequiped:
In some steel strand 2 tip position near barrel place, selected hoist engine 3 installation site, carries out repacking to the slip form platform support body 1 of installation site and reinforces.
S2, hoist engine 3 are installed:
Slip form platform support body 1 after repacking is reinforced installs hoist engine 3, and the stability of hoist engine 3 must meet the dilatory work of follow-up steel strand 2.
S3, barrel steel strand fixed mount 4 are installed, centering:
First steel strand 2 on the estimation need the track laid to install some steel strand fixed mounts 4, and utilize steel strand fixed mount 4 to replace the vertical distributing bar of part barrel.
Wearing in advance of S4, hoist engine 3 wire rope 5:
As Fig. 1, by the steel strand fixed mount 4 of wire rope 5 fag end on hoist engine 3 through round silo, until steel strand 2 tip position.
The connection of S5, steel strand 2 and wire rope 5:
As Fig. 2, utilize steel cable clamp 6, by wire rope 5 fag end and the parallel connection in steel strand 2 termination, the rubber pad 7 that buckle 6 and steel strand 2 contact position pad prevent steel strand in pulling to be damaged.
S6, regain wire rope 5 with hoist engine 3, artificial fine setting is in place to steel strand 2, unties the connection between wire rope 5 and steel strand 2, steel strand 2 and steel strand fixed mount 4 is tightened by tied silk.
The present invention proposes a kind of semi-mechanization steel strand laying method for round silo, principle of the present invention is exactly that former should utilization is laid steel strand personnel thrust in the wings and changed into hoist engine 3 and tighten up wire rope 5 in front and the pulling force that brings steel strand 2; Hoist engine 3 should slowly tighten up; When tightening up, steel strand 2 are other establishes operating personnel to guard, and prevents steel strand 2 from causing damage with steel strand fixed mount 4 is stuck, and after steel strand 2 are in place, personnel remove steel strand 2 and the connection of wire rope 5 immediately, steel strand 2 and steel strand fixed mount 4 are tightened by tied silk.
Above content is only to design example of the present invention and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the design of invention or surmount this scope as defined in the claims, protection scope of the present invention all should be belonged to.
