Abstract
The utility model provides a slope reinforcement structure supported by glass fiber pre-stressed soil nails. The slope reinforcement structure comprises a slope formed by excavating in a soil body, wherein slanted glass fiber pre-stressed soil nails are arranged in the soil body of the slope. When in use, the strength of the soil body of the foundation pit can be greatly increased by applying the glass fiber pre-stressed soil nails of the utility model to the support of the foundation pit; the deformation of the soil body of the slope can be effectively restrained by the stress, thus significantly improving the stability of the foundation pit; moreover, by using the support, to which the glass fiber pre-stressed soil nails are applied, the soil nails are not required to be removed, and the glass fiber pre-stressed soil nails can be easily cut off, thus avoiding the impact on the follow-up operation.
Description
Technical field
The utility model relates to construction engineering technical field, concrete relates to a kind of slope reinforcement structure that adopts the supporting of reinforced plastic glass fibre prestressing force soil nailing.
Background technology
Building underground structure needs excavation pit, but because the slope soil self stability is not enough, need handle the compound side slope that has certain intensity with formation to the excavation slope soil body.Soil nailing is to constitute by technologies such as pore-forming, joint bar, slip castings in the natural soil body.Side slope or the body of wall of having squeezed into soil nailing then become plate brad supporting, form the soil pressure after a similar gravity barricade comes resistance wall, thereby guarantee the stable of excavation face.
Existing soil nailing muscle body is generally reinforcing bar or steel pipe.Have following defective: 1 removes difficulty, can not remove substantially, also takes time and effort even remove.2 cutting performances are poor, damage cutting equipment easily during the cutting of construction back, and the soil body that then adopts reinforcing bar body soil nailing to reinforce can influence the construction of this soil layer later stage underground construction.3 weight are heavier, the actual inconvenience of using.
The utility model content
Technical problem to be solved in the utility model is, overcome problems of the prior art, a kind of slope reinforcement structure that adopts the supporting of reinforced plastic glass fibre prestressing force soil nailing is provided, this kind slope reinforcement structure, both can reach the intensity of reinforcing bar soil nailing, be easy to cutting again, make that the soil body after reinforcing does not influence the construction of engineering on every side.
In order to address the above problem the technical solution of the utility model is such:
A kind of slope reinforcement structure that adopts the supporting of reinforced plastic glass fibre prestressing force soil nailing is included in the side slope that excavation forms in the soil body, is provided with oblique reinforced plastic glass fibre prestressing force soil nailing in the slope soil.
Described reinforced plastic glass fibre prestressing force soil nailing can be the solid hopkinson bar body, also can be hollow rod body.
Described reinforced plastic glass fibre prestressing force soil nailing be the threaded rod structure, an end of threaded rod is provided with pallet, the pallet rear end is provided with a nut.
Described reinforced plastic glass fibre prestressing force soil nailing can apply prestressing force.
Beneficial effect is applied in reinforced plastic glass fibre prestressing force soil nailing described in the utility model supporting in foundation ditch, the slope reinforcement during use, by prestressing force can more effective constraint slope soil distortion, significantly improve the stability of side slope.And the slope reinforcement of employing reinforced plastic glass fibre prestressing force soil nailing, construction finishes and need not extract soil nailing, in other follow-up work progresss, can cut off reinforced plastic glass fibre prestressing force soil nailing easily, and follow-up work is had no effect.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structural representation of reinforced plastic glass fibre prestressing force soil nailing described in the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1
Be reinforced plastic glass fibre prestressing force soil nailing among Fig. 1, comprise a body of rod 1, the body of rod 1 is made for the reinforced plastic glass fibre material, has stronger resistance to tension, has more weak shear resistance simultaneously, squeezes into to be convenient in the soil layer shear to break.
The supporting of described reinforced plastic glass fibre prestressing force soil nailing is mainly used in building foundation pit supporting and the slope reinforcement, promptly is provided with several reinforced plastic glass fibre prestressing force soil nailings around foundation ditch, and the direction of squeezing into of soil nailing is oblique.With the same intensity that can improve soil mass of foundation pit of soil nailing of steel, and, significantly improve the stability of foundation ditch by applying the distortion that prestressing force effectively retrains slope soil.But since its shear resistance a little less than, be convenient to cut off, after the construction, stay in the soil layer, do not influence other construction works.
Described reinforced plastic glass fibre prestressing force soil nailing 1 can be the solid hopkinson bar body, also can be hollow rod body.The diameter and the length of the corresponding body of rod can be determined according to actual conditions.
Reinforced plastic glass fibre prestressing force soil nailing 1 be the threaded rod structure, an end of threaded rod is provided with pallet 2, the pallet rear end is provided with a nut 3.After soil nailing was squeezed into, pallet 2 and nut 3 carried out stretch-draw and lock.Can certainly not want pallet.Cooperate the tension effect as long as can play.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
