Abstract
The utility model relates to a sleeve type bottom-conveying rear grouting device for a later-inserted pipe. Due to the fact that the construction process of a grouting pile adopted in existing construction has the defects of being limited, unreasonable in firmness, tedious and complex, pressing and grouting are carried out by a steel pipe which is inserted later on cement paste immediately on the situation that pressing and grouting of concrete are accomplished, and the concrete is in a flowing state, the concrete cannot achieve final setting hardening, and cannot constrain the pressure cement paste, and the effect for improving the bearing capacity of a single pile is not obvious. The sleeve type bottom-conveying rear grouting device for the later-inserted pipe comprises a grouting pipe (1), wherein the grouting pipe is installed in a tool type steel sleeve (2), a vibrating tamper (3) and a grouting pipe guiding head (4) are connected with the two ends of the tool type steel sleeve respectively, the other end of the vibrating tamper is connected with a lifting steel wire rope (5), the tool type steel sleeve is provided with a lifting grouting pipe opening (6), and the grouting pipe is provided with a grouting hole (7). The sleeve type bottom-conveying rear grouting device for the later-inserted pipe is applied to construction.
Description
technical field:
the utility model send rear intubate post-grouting device at the bottom of relating to a kind of bushing type.
background technology:
construction market a kind of technique used is < < auger stem center pump-injecting concrete pile-forming after-inserted pipe grouting device > > at present, this installs existent defect, after the steel pipe that inserts be immediately to carry out grouting methol pressing to have filled with under the mobile state of concrete, because concrete reaches final set sclerosis, press water mud is not had to restraint forces, to pile body, the densification completely of the stake end soil body, so to improving bearing capacity of single pile DeGrain.
another < < long auger presses filling stake grouting behind shaft or drift lining processing method and rearmounted Grouting Pipe device > > thereof to have several shortcomings to be: 1, limitation: described in the method claim 1 step 1: this postposition Grouting Pipe device and reinforcing cage link into an integrated entity, Grouting Pipe material requirements must be steel pipe, and slip casting steel pipe must be tied up, be welded on reinforcing cage, the length of current specifications regulation reinforcing cage is that stake is long by 2/3rds, Grouting Pipe just grows 1/3rd than reinforcing cage, increased span (L) value moment of flexure also strengthens thereupon, when lifting, slip casting steel pipe insufficient rigidity causes bending, there is no operability, if be equipped with crane, can increase considerably irrational cost.2, irrational fastness: described in the method right 7,10: taper pocketed thing is drawn and welded in above-mentioned pile grouting pipe and stake side Grouting Pipe and the colligation of spacer bars circle or the reinforcing cage lower end in welding and reinforcing cage garden week in to center of circle bending.Due at the bottom of Grouting Pipe needs dynamic driving to arrive, need enough rigidity and fastnesses to realize, the measure that employing is welded on reinforcing cage solves, also set up pocketed reinforcing bar material reinforcement of weld, solve a problem for stake bottom 1/3rd insufficient rigidity, irrational increased welding material, artificial, equipment, etc. cost.Attached workload is greater than groundwork amount.3, triviality: described in the method claim 5: this device comprises and be placed in pile body ring week at least, two pile grouting pipes, at least one pile side Grouting Pipe are welded on spacer bars circle and reveal all the details on reinforcing bar.Due to the unreasonable reinforcement cost that increased of slip casting penstock installation method, drilling & grouting piling concrete pile can construction diameter generally in 800mm, conventionally adopt a Grouting Pipe just can meet the demands, steel pipe of this invention cannot be located and be laid, so in order to meet smooth Laying injection pipe requirement, designed two slip casting steel pipes.Caused the upper irrationality of design and wasted.4, complexity: described in the method claim 1 step 7: cement paste is to go out from slip casting one way valve, in engineering practice, do not use one-way cock, in practice, practical operation is after the boring of Grouting Pipe bottom, directly with adhesive tape, just wraps and can meet slip casting requirement.
summary of the invention:
the purpose of this utility model is sent rear intubate post-grouting device at the bottom of being to provide a kind of bushing type.
above-mentioned object realizes by following technical scheme:
at the bottom of a kind of bushing type, send rear intubate post-grouting device, its composition comprises: Grouting Pipe, described Grouting Pipe is arranged in tool-type steel sleeve, and described tool-type steel sleeve two ends connect respectively vibrator and Grouting Pipe guide head, and the described vibrator other end connects lifting wire rope; Described tool-type steel sleeve has the slip casting of the hanging mouth of pipe, and described Grouting Pipe has injected hole.
at the bottom of described bushing type, send rear intubate post-grouting device, hang Grouting Pipe wire rope by hanging the slip casting mouth of pipe and connecting described Grouting Pipe on described tool-type steel sleeve.
the beneficial effects of the utility model:
1. the utility model send rear intubate post-grouting device device at the bottom of providing a kind of bushing type, can solve at concrete and flow under state, insert Grouting Pipe the instant cement injection densification soil body, to improving the unconspicuous problem of single pile bearing capacity, in short cast-with-pressure concrete pile during Laying injection pipe, both can adopt manpower also can adopt other auxiliary strength that Grouting Pipe is directly installed, have advantages of that work progress is easy, and that whole device also has cost is low, lay conveniently, manufacturing process is simple, reliable in quality, Grouting Pipe material has multiple choices, with low cost, increase social benefit, be convenient to the advantage of promoting.
the utility model is that Grouting Pipe is enclosed within after sending into design soil layer in tool-type steel sleeve and extracts steel sleeve; it is whole that to send into process direct; the speed of sending into is separately fast; and there is the protection of tool-type steel sleeve Grouting Pipe outside; tool-type steel sleeve can be reused, and operation independent operation does not relate to the reinforcement cost problem of reinforcing cage.
accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present utility model.
the specific embodiment:
embodiment 1:
at the bottom of a kind of bushing type, send rear intubate post-grouting device, its composition comprises: Grouting Pipe 1, described Grouting Pipe is arranged in tool-type steel sleeve 2, and described tool-type steel sleeve two ends connect respectively vibrator 3 and Grouting Pipe guide head 4, and the described vibrator other end connects lifting wire rope 5; Described tool-type steel sleeve has the slip casting of the hanging mouth of pipe 6, and described Grouting Pipe has injected hole 7.
embodiment 2:
at the bottom of bushing type described in embodiment 1, send rear intubate post-grouting device, hang Grouting Pipe wire rope 8 by hanging the slip casting mouth of pipe and connecting described Grouting Pipe on described tool-type steel sleeve.
Claims (2)
1. at the bottom of a bushing type, send rear intubate post-grouting device, its composition comprises: Grouting Pipe, it is characterized in that: described Grouting Pipe is arranged in tool-type steel sleeve, described tool-type steel sleeve two ends connect respectively vibrator and Grouting Pipe guide head, and the described vibrator other end connects lifting wire rope; Described tool-type steel sleeve has the slip casting of the hanging mouth of pipe, and described Grouting Pipe has injected hole.
