Abstract
The invention discloses a rock and soil anchoring structure. The rock and soil anchoring structure comprises an anchor head, an anchor rod body, a free section, an anchoring section and auxiliary anchoring sections. The anchor head is fixed to a retaining structure and connected with one end of the anchor rod body. The other end of the anchor rod body stretches into rock and soil to form the free section and the anchoring section. The auxiliary anchoring sections and the anchoring section intersect. A grouting body connected into a whole is arranged in the anchoring section and the auxiliary anchoring sections. By means of the rock and soil anchoring structure, the auxiliary anchoring sections and the anchoring section intersect, the grouting body connected into the whole is arranged in the anchoring section and the auxiliary anchoring sections, a linear structure of an anchor rod in the prior art is changed, adhesive friction force can be formed in multiple directions, the adhesive friction force between the anchoring section and a surrounding rock and soil medium is enhanced, and the pulling resistance of the rock and soil anchoring device is improved.
Description
Technical field
The present invention relates to a kind of civil engineering facility, particularly a kind of ground anchored structure.
Background technology
Anchorage Technology imbeds in stratum by a kind of tension member, to improve a kind of engineering of ground self-strength and self-stable ability, because this technology alleviates the deadweight of works greatly, save engineering material, and guarantee that the safety of engineering is with firm, there is significant economic benefit and social benefit, therefore be widely used in engineering, Anchorage Technology utilizes anchor pole surrounding formation rock soil classifiction to carry out the pulling force of transferring structure thing, or keep the homeostasis of stratum excavation face, it can provide and act on works to bear the drag of outer lotus, works and stratum can be made to be bound up, form a kind of cooperative complex, can effectively bear pulling force and shearing, anchor pole of the prior art generally includes anchor head, free segment and anchoring section, the bearing capacity of anchor pole mainly relies on shank member particularly anchoring section and cohere frictional force around between rock soil medium, and the anchoring section that prior art adopts is straight line structure, often frictional force is limited, particularly when Impact direction and anchor pole angular separation less, if run into soil layer cohere frictional strength lower time, often be difficult to the requirement meeting design uplift resistance, therefore, need a kind ofly can form the ground anchored structure cohering frictional force in a plurality of directions.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the problems referred to above, provides one to have supplementary anchorage segment structure, can form the ground anchored structure cohering frictional force in a plurality of directions.
To achieve these goals, the technical solution used in the present invention is such: ground anchored structure of the present invention, comprise anchor head, anchor bar body, free segment, anchoring section and supplementary anchorage section, described anchor head is fixed on retaining structure and one end of connection anchor bar body, the described anchor bar body other end stretches in ground and forms free segment and anchoring section, described supplementary anchorage section is intersected crossing with anchoring section, and the inside of described anchoring section and supplementary anchorage section is connect into an overall injecting cement paste.
Further, as a kind of concrete form of structure, supplementary anchorage section of the present invention is positioned at the both sides up and down of anchoring section.
Further, as a kind of concrete form of structure, the quantity of supplementary anchorage section of the present invention is more than 2.
Further, as a kind of concrete form of structure, the end of anchoring section of the present invention is that head body is expanded in end.
Further, as a kind of concrete form of structure, the injecting paste material of injecting cement paste of the present invention is cement mortar.
Compared with prior art, the invention has the advantages that: this ground anchored structure adopts described supplementary anchorage section to intersect crossing with anchoring section, the inside of described anchoring section and supplementary anchorage section is connect into an overall injecting cement paste, change the linear structure of anchor pole in prior art, can be formed in a plurality of directions and cohere frictional force, strengthen anchoring section and cohere frictional force around between rock soil medium, improving the uplift resistance of this ground anchored structure.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
In figure: 1. anchor head; 2. anchor bar body; 3. free segment; 4. anchoring section; 5. supplementary anchorage section; 6. head body is expanded in end; 7. retaining structure.
Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation, and these accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention is described in a schematic way, and therefore it only shows the formation relevant with the present invention.
The preferred embodiment of ground anchored structure of the present invention as shown in Figure 1, comprise anchor head 1, anchor bar body 2, free segment 3, anchoring section 4 and supplementary anchorage section 5, described anchor head 1 is fixed on retaining structure 7 and one end of connection anchor bar body 2, described anchor bar body 2 other end stretches in ground and forms free segment 3 and anchoring section 4, described supplementary anchorage section 5 is intersected crossing with anchoring section 4, the inside of described anchoring section 4 and supplementary anchorage section 5 is connect into an overall injecting cement paste, described supplementary anchorage section 5 is positioned at the both sides up and down of anchoring section 4, the quantity of described supplementary anchorage section 5 is more than 2, the end of described anchoring section 4 is that head body 6 is expanded in end, the injecting paste material of described injecting cement paste is cement mortar.
Ground anchored structure of the present invention adopts described supplementary anchorage section 5 to intersect crossing with anchoring section 4, described supplementary anchorage section 5 can by punching, fill formation, the inside of described anchoring section 4 and supplementary anchorage section 5 is made to be connect into an overall injecting cement paste, change the linear structure of anchor pole in prior art, can be formed in a plurality of directions and cohere frictional force, strengthen anchoring section 4 and cohere frictional force around between rock soil medium, improve the uplift resistance of this ground anchored structure, described supplementary anchorage section 5 is positioned at the both sides up and down of anchoring section 4, make the both sides up and down of anchoring section 4 be subject to holdback force simultaneously, what increase this ground anchored structure entirety coheres frictional force, the quantity of described supplementary anchorage section 5 is more than 2, quantity is more, breakout capacity is stronger.The end of described anchoring section 4 is that head body 6 is expanded in end, the bearing capacity of anchoring section 4 holds intensity by the end of the frictional strength between anchor bar body 2 and the soil body and enlarged footing body and jointly provides, improve the bearing capacity of anchoring section 4, the injecting paste material of described injecting cement paste is cement mortar, it is simple to operate, only need add a certain amount of water at the construction field (site), can use after stirring.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff completely can in the scope not departing from this invention technological thought, carry out various change and amendment, the technical scope of this invention is not limited to the content on manual, must determine its technical scope according to right.
