Abstract
The utility model relates to a sleeve pipe moisture injection process type steel sleeve pipe which comprises a pipe body, wherein at least two locking mechanisms used for supporting engineering piles are distributed on the inner wall at the tail end of the pipe body, one end of a steel wire rope penetrates through all the locking mechanisms to form a circle, the other end is connected with a traction device, and the locking mechanisms are separated from the pipe body and support the engineering piles under the driving of the steel wire rope. By adding the locking mechanisms, the steel wire rope can completely fasten all engineering piles, so that all piles can be extracted out at one time. The sleeve pipe moisture injection process type steel sleeve pipe satisfied the technological requirement of pile extraction and has simple structure, good generality, convenience for use and safety and reliability.
Description
Technical field
The utility model relates to a kind of sleeve water gas jet method steel sleeve device for modifying, can effectively pull out Prefabricated Reinforced Concrete Square Pile.
Background technology
Sleeve water gas jet method is a kind of construction technology that Prefabricated Reinforced Concrete Square Pile is pulled out, and it is to utilize the sleeve pipe process under the effect of vibrating hammer, squeezes into pile peripheral earth, destroys the frictional force of stake and surrounding soil, uses a kind of method of loop wheel machine pile pulling again.
The operating principle of steel sleeve water vapor injection method construction equipment is as shown in Figure 1: this method be utilize-individual with to pull out stake isometric or slightly be shorter than the steel pipe sleeve pipe 2 of pulling out stake; Around steel pipe sleeve pipe 2, offer some spilling water holes, arrange 1 group of water under high pressure, airway and shower nozzle respectively in the outside and the inboard of steel pipe sleeve pipe 2 simultaneously.When steel sleeve pipe 2 under hydraulic electric vibrating hammer 1 effect; Steel sleeve pipe 2 is covering the required engineering piles of pulling out 3 and is slowly squeezing in the soil; The high pressure nozzle of the 1 group of water in steel sleeve pipe 2 ends, gas unification is with the soil body scour out mud between engineering piles 3 and the steel sleeve pipe 2, by the stake end of flowing out, being sink to until steel sleeve pipe 2 engineering piles 3 that need pull out in the spillway hole around steel sleeve pipe 2 walls; Propose steel sleeve pipe 2, then utilize crane gear to pull out required 1 of the engineering piles of pulling out and accomplish the pile pulling operation.
Yet, in the process of pile pulling often because steel sleeve pipe 2 when soil is cut in sinking, collides the pile body of engineering piles 3 broken pile takes place easily.In case the generation broken pile just can not once be extracted putting in order pile.
Summary of the invention
The purpose of the utility model provides a kind of sleeve structure that is used for sleeve water gas jet method that can broken pile be pulled out fully.
In order to achieve the above object; The technical scheme of the utility model has provided a kind of sleeve water gas jet method steel sleeve; Comprise body, it is characterized in that: on the inwall of body end, be distributed with at least two, form ring-type after an end of wire rope passes all retaining mechanisms in order to prop up the retaining mechanism of engineering piles; The other end connects draw-gear, and retaining mechanism breaks away from body and props up engineering piles under the drive of wire rope.
Preferably, said retaining mechanism is a round steel, an end of round steel and said body spot welding, and the other end is in order to prop up said engineering piles.
Preferably, said draw-gear is a crawler crane.
The utility model makes that through increasing retaining mechanism wire rope can be with the complete fastening of engineering piles, thereby can whole stake once be extracted.The utility model has satisfied the pile pulling technological requirement, and simple in structure, versatility good, esy to use, safe and reliable.
Description of drawings
Fig. 1 is the fundamental diagram of steel sleeve water vapor injection method construction equipment;
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
The specific embodiment
For making the utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
A kind of sleeve water gas jet method steel sleeve as shown in Figure 2, that the utility model provides comprises body 4; On the inwall of body 4 ends, be uniformly distributed with four round steel 6; One end of round steel 6 and body 4 spot welding, the other end is in order to prop up four faces of engineering piles 3 respectively, and an end of wire rope 5 passes all round steel 6 backs and forms ring-type; The other end connects crawler crane, and round steel 6 breaks away from body 4 and props up engineering piles 3 under the drive of wire rope 5.
During work, wire rope 5 one ends are strained by crawler crane, and the other end is aimed at engineering piles 3 along body 4 and is inserted in, and wire rope 5 keeps sinking with speed with body 4, notes keeping the tensioned state of wire rope 5 in the sinking process, in case wire rope 5 landing in the sinking process.Deliver to the above 0.2m in stake top of engineering piles 3 when wire rope 5 after; Crawler crane suitably loosens wire rope 5, and after finding out the instrument in main frame that wire rope 5 falls to the following 1m in stake top of engineering piles 3, crawler crane tightens up wire rope 5; Because round steel 6 and body 4 spot welding; Wire rope 5 can be broken the spot welding position, and engineering piles 3 is tied tight, can begin pile pulling.
When adopting the pile pulling of steel sleeve water vapor injection method, generally can cause about old stake sinking 1-2m, cause the wire rope 5 can't the old stake of hitch,, can effectively wire rope 5 covers be fastened old stake, average pile pulling every day 3-4 root according to above-mentioned flow process.
