The multifunctional casing fitting is suitable for the fields of water conservancy and hydropower engineering, municipal traffic engineering, construction site engineering and the like.
Description
Technical field
The utility model relates to a kind of Multifunctional cover pipe fitting.Be applicable to the fields such as Hydraulic and Hydro-Power Engineering, municipal traffic engineering and building lot engineering.
Background technology
All buildings that relate to are all to high level, deep layer, large tracts of land, heavy-duty future development, the application quantity of anchor pole in Rock And Soil stabilization works, support engineering also increasing, range of application is more and more extensive, and innovation or the useful improvement of this field of engineering technology and construction technical method had important engineering significance and economic worth.
Present stage anchor rod construction method and operation comparatively loaded down with trivial details, every procedure all need consume plurality of devices cost, time cost and human cost.In the soil bolt construction, for the bad Rock And Soil of engineering geology, easily cave in as in loosening sand and soft layer, holing, cave in is because limited the causing of boring self-stable ability of the bad Rock And Soil of engineering geology, particularly finish but anchor pole is not put in boring, in the uncompleted time of slip casting, cause anchor pole not insert smoothly behind the borehole collapse, to carry out first backfill to the processing in the hole that caves in generally, carry out after the slip casting cure process again pore-forming, waste time and energy, cause economic waste, the quality of rear pore-forming can not guarantee, the mechanical property of position, the hole soil body that collapses also decreases.Can not accurately hold construction precision during construction, free section and anchoring section length can not be accurately by the design load location, and anchor pole inserts by the problems such as sideslip, topping deficiency often occurring.
Summary of the invention
The technical problems to be solved in the utility model is: for the problem of above-mentioned existence, provide a kind of Multifunctional cover pipe fitting simple in structure, easy to make and with low cost, to simplify working procedure, improve the construction construction precision, reducing construction cost.
The technical scheme that the utility model adopts is: a kind of Multifunctional cover pipe fitting, it is characterized in that: described casing fitting is formed by several cylinder unit spliceds, each cylinder unit is provided with three passages vertically, is respectively the anchor pole passage of central authorities and slip casting passage and the exhaust passage that is positioned at anchor pole passage both sides.
Connect by draw-in groove between the adjacent column body unit.
Lowermost end in the exhaust passage arranges the anti-filter film.
The external cylindrical surface of described cylinder unit is marked with scale.
Adopt the job practices of Multifunctional cover pipe fitting injection anchor pole, comprise step:
1, at first determines the anchor pole position, hole at a certain angle to projected depth and clear hole;
2, meanwhile, splice the cylinder unit on ground by described projected depth, and in the anchor pole passage, insert anchor pole, in the slip casting passage, insert the slip casting flexible pipe, the outer end of slip casting flexible pipe connects grouting pump, at the lowermost end of exhaust passage the anti-filter film is installed, and forms casing fitting for subsequent use;
3, inserting step 2 ready casing fittings in boring immediately behind the clear hole;
4, start grouting pump by the slip casting flexible pipe to the boring hole-bottom slurry-injection, the cylinder unit that links to each other is dialled on marginal not slurry limit outward, the unnecessary cylinder unit that simultaneously dismounting exposes;
5, control anchor rod anchored section length by the scale on the cylinder unit external cylindrical surface, after slip casting is finished, after slurry reaches design strength, in the aperture anchor pole is carried out stretch-draw;
6, after stretch-draw is finished, anchor head and ground tackle are installed are fixed;
7, the cylinder unit of still staying in the boring forever keeps as the disrance sleeve of free section.
The beneficial effects of the utility model are: 1) full section retaining wall after the boring, borehole collapse when preventing construction operation.2) the Multifunctional cover pipe fitting is made by standardization, selects the PVC material, on a large scale Prefabrication.3) Multifunctional casing plays the centering effect in work progress, substitutes medium-height trestle.4) can play the buffer action of prestressed anchor free segment and slurry, play simultaneously the effect that prevents the corrosion of free segment anchor pole.5) Multifunctional casing has the usefulness of slip casting passage concurrently.6) Multifunctional casing is marked with scale, can precisely determine free section and anchoring section length during construction.7) disassembled mode connects between Multifunctional casing, can control length according to actual conditions, convenient construction.8) the recyclable recycling of Multifunctional casing under disassembling.9) efficiency of construction is high.

The specific embodiment
As shown in Figure 1 and Figure 2, the present embodiment is a kind of Multifunctional cover pipe fitting, be spliced by several cylinder unit 1, each inside, cylinder unit is provided with three passages vertically, be respectively anchor pole passage 3, slip casting passage 4 and exhaust passage 5, wherein the anchor pole passage 3, are positioned at the centre of casing fitting 1, slip casting passage 4 is positioned at the bottom near cylinder unit 1, and exhaust passage 5 is positioned at the top near cylinder unit 1.As shown in Figure 3, on cylinder unit 1 external cylindrical surface scale 6 is set, connects by draw-in groove 7 between the cylinder unit 1, the length of every cylinder unit 1 can be undertaken according to designing requirement prefabricated by 1 meter or 0.5 meter, also can different sizes be set according to specific requirement.
Adopt the concrete construction method of Multifunctional cover pipe fitting injection anchor pole as follows in the present embodiment:
1, at first through calculating, position, the anchor pole of determining armature boring arrange angle, anchor pole overall length, anchor rod anchored segment length and freedom length, then adopt suitable boring method to be drilled to projected depth in the precalculated position, for example adopt augers, the first-class boring method of Churn drill, and carry out clearly hole;
2, meanwhile, splice cylinder unit 1 on ground by described projected depth, and at anchor pole passage 3 interior insertion anchor poles 2, at slip casting passage 4 interior insertion slip casting flexible pipes 8, the outer end of slip casting flexible pipe connects grouting pump 9, and 5 lowermost end is installed anti-filter film 10 in the exhaust passage, forms casing fitting for subsequent use;
3, immediately the ready Multifunctional cover pipe fitting of above-mentioned steps 2 splicings is inserted in the boring behind the clear hole, prevent long-time borehole collapse, can play follow-up work progress to the retaining wall effect of boring after casing fitting inserts;
4, start grouting pump 9 and carry out hole-bottom slurry-injection by slip casting flexible pipe 8, in the slip casting process, hole base space slip casting is occupied by slurries, and unnecessary air can efflux by exhaust passage 5; Simultaneously according to pulling out continuous (by draw-in groove 7) cylinder unit 1 outside control grouting amount or the grouting pressure marginal not slurry limit, pull out in the process outward, only guarantee to pull out cylinder unit 1 and anchor pole 2 is motionless outward, the unnecessary cylinder unit 1 that expose in the aperture when pulling out outward can be dismantled and recycle;
5, according to the observation of the scale 6 on cylinder unit 1 external cylindrical surface, can precisely finish anchor rod anchored section slip casting, control anchor rod anchored section length; After slip casting is finished, after slurry reaches design strength, in the aperture anchor pole 2 is carried out stretch-draw;
6, after stretch-draw is finished, anchor head and ground tackle are installed are fixed;
7, stay still that remaining cylinder unit 1 forever keeps as the disrance sleeve of anchor pole 2 free segments in the boring, permanent disrance sleeve plays isolation and protects two kinds of effects simultaneously.
