Abstract
The utility model discloses a recoverable FRP stock with enlarged footing moves about freely and quickly to arrange and implement excavation supporting on the foundation ditch is domatic, the FRP stock that has included supprot effect, the foundation ditch bury the enlarged footing piece that pours into the grout into after the drilling and form in domatic underground, the enlarged footing piece bonds has the stock to strengthen the body, and body threaded connection is strengthened to FRP stock and stock, the FRP stock expose outward the domatic outer end of foundation ditch be equipped with with the FRP stock connects into holistic channel -section steel with great ease. The utility model discloses an at the internal enlarged footing piece of burying high -pressure slip casting formation underground in foundation ditch slope to the pre -buried stock enhancement that bonds in the enlarged footing piece is personally experienced sth. Part of the body, with realizing satisfying excavation supporting under the national energy saving and emission reduction requirement prerequisite behind FRP stock and the stock enhancement body threaded connection, has improved the resistance to corrosion of stock, and it is recoverable to strut the end stock, saving construction cost.
Description
Technical field
The utility model relates to construction engineering technical field, especially a kind of recyclable FRP anchor pole with enlarged footing.
Background technology
In order to build a conservation-minded society, country more and more strengthens the requirement of energy-saving and emission-reduction, especially increases the research to environmental protection new material at building field.In existing foundation pit supporting construction, main employing steel concrete is as structural member, under the environment for use of, foundation depth h≤8m thicker at mucky soil, steel concrete exists certain not enough in tensile strength and resistance to corrosion, also the difficult requirement meeting energy-saving and emission-reduction, and FRP is as wherein more ripe fibrous material, has stronger tensile strength, can reinforcing bar be substituted, realize foundation ditch anchoring.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of and meets energy-saving and emission-reduction requirement, realize the recyclable FRP anchor pole with enlarged footing of foundation ditch anchoring and use this anchor pole
The utility model solves the technical scheme that its technical problem adopts: a kind of recyclable FRP anchor pole with enlarged footing, be arranged in the domatic upper enforcement pattern foundation pit supporting structure of foundation ditch in length and breadth, comprise the FRP anchor pole of support action, after being embedded with boring in described foundation ditch is domatic, cement paste is injected and the enlarged footing block of formation, described enlarged footing block is built-in with anchor pole intensive aspect, FRP anchor pole is threaded with anchor pole intensive aspect, and FRP anchor pole exposes outside the domatic outer end of foundation ditch and is provided with the channel-section steel described FRP anchor pole being connected into entirety.
Preferably, the strong rubber knot slurry that described anchor pole intensive aspect adopts magnesium phosphate cementitious materials to prepare solidifies and forms.
Described FRP anchor pole the inner has the screw thread be connected with anchor pole intensive aspect.
The beneficial effects of the utility model are: cement paste injects and the enlarged footing of formation by the utility model by be embedded with boring in the body of foundation ditch slope after, and on enlarged footing block Grouted bolt intensive aspect, pattern foundation pit supporting structure is carried out after being threaded with anchor pole intensive aspect by FRP anchor pole, meet national energy-saving reduce discharging require prerequisite under, improve the resistance to corrosion of anchor pole, it is recyclable that supporting terminates anchor pole, saves construction cost.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is mounting structure schematic diagram of the present utility model.
In figure, 1.FRP anchor pole 2. enlarged footing block 3. anchor pole intensive aspect 4. channel-section steel 5. foundation ditch is domatic
Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of recyclable FRP anchor pole with enlarged footing as shown in Figure 1, be arranged in length and breadth on foundation ditch domatic 5 and implement pattern foundation pit supporting structure, comprise the FRP anchor pole 1 of support action, after being embedded with boring in described foundation ditch domatic 5, cement paste is injected and the enlarged footing block 2 of formation, described enlarged footing block 2 is built-in with anchor pole intensive aspect 3, the strong rubber knot slurry that described anchor pole intensive aspect 3 adopts magnesium phosphate cementitious materials to prepare solidifies and forms, FRP anchor pole 1 inner end has screw thread, FRP anchor pole 1 is threaded with anchor pole intensive aspect 3, the outer end that FRP anchor pole 1 exposes outside foundation ditch domatic 5 is provided with the channel-section steel 4 described FRP anchor pole 1 being connected in length and breadth entirety.
The construction technology step using the above-mentioned recyclable FRP anchor pole with enlarged footing to carry out pattern foundation pit supporting structure is as follows:
A, by construction requirement, the drill bit with the planning function is adopted to follow bar drill shot borehole on foundation ditch domatic 5, foot of hole ream forming, counter bore diameter is 400mm, gets into the anchor layer backed off after random drilling rod of design, to hole in be pressed into cement paste, grouting pressure 2 ~ 4Mpa, water/binder ratio 0.55, makes the slurry of reaming place form enlarged footing block 2, the enlarged footing block 2 diameter 400mm formed, thickness 250mm;
Be pressed into the strong rubber knot slurry prepared by magnesium phosphate cementitious materials in b, drill bit and form anchor pole intensive aspect 3, anchor pole intensive aspect 3 is firmly cementing with enlarged footing block 2;
C, FRP anchor pole 1 diameter is that 80mm, FRP anchor pole 1 tunnels with drilling rod with anchor pole intensive aspect 3, is threaded by FRP anchor pole 1 inner end with anchor pole intensive aspect 3;
The outer end that d, FRP anchor pole 1 exposes outside foundation ditch domatic 5 is that described FRP anchor pole 1 is connected into entirety by the channel-section steel 4 of 14# in length and breadth by specification;
At the end of e, base pit engineering, remove channel-section steel 4, FRP anchor pole 1 is reversely rotated after exiting anchor pole intensive aspect 3 and reclaim.
The utility model is injected by cement paste and the enlarged footing block 2 that formed by burying underground in foundation ditch domatic 5, and on enlarged footing block 2 Grouted bolt intensive aspect 3, pattern foundation pit supporting structure is carried out after being threaded with anchor pole intensive aspect 3 by FRP anchor pole 1, meet national energy-saving reduce discharging require prerequisite under, improve the resistance to corrosion of anchor pole, it is recyclable that supporting terminates anchor pole, saves construction cost.
Above-mentioned embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
