Description
Technical field
The utility model is related to Geotechnical Engineering, and the major landslip more particularly on the poor Rock soil Foundation of intensity reinforces work
Journey.
Background technology
Substantial amounts of major landslip is distributed with Southwestern China mountain area, engineering construction is usually taken the mode of passing round and passed through, but with
A large amount of progress of engineering construction, occurs in that many engineering constructions can not pass round the case of major landslip, antiskid can only be taken to arrange
Apply and major landslip is reinforced.Reinforced generally using multiple rows of friction pile, compound antiskid structure, anchor cable currently for major landslip
It is such as the poor ground of soil layer, carbonaceous shale equal strength when foundation condition below the engineering measures such as stake, but landslide sliding surface is poor
During body, because subgrade reaction is poor, traditional friction pile needs to be reinforced using the profound stake in plurality of rows of heavy in section, anchored pile
Because foundation condition is poor, the anchor force that can be provided is smaller and long durability has problem, therefore should not use.In such case
Under, the reinforcing on landslide typically encounters the technical barriers such as huge construction investment, engineering construction cycle length, constructional difficulties, therefore, urgently
A kind of new landslide reinforcement structure is needed to solve problems.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of anchoring type reinforcement structure, to optimize friction pile
Stress performance, strengthen the anti-slide performance of friction pile, and save construction investment.
The utility model solves the technical scheme that its technical problem used：
A kind of anchoring type reinforcement structure of the present utility model, including the friction pile being arranged in slip mass, its feature
It is：The inner side position of slip surface of the friction pile has grappling key, and grappling key top exposes sliding surface；Antiskid stake top is fixed on the outside of anchor cable
Portion, inner side is connected with grappling key；Body backfill is backfilled in the construction retaining wall in grappling key top portion.
The beneficial effects of the utility model are, using the less cantilever segment of grappling key and larger anchoring section, to pass through anchor cable
Effect larger anchoring pulling force can be provided for friction pile, so as to optimize the stress performance of friction pile, enhancing friction pile it is anti-
Sliding ability, and construction investment is saved, structure durability is good, difficulty of construction is small, good economy performance, with wide popularizing application prospect.
Brief description of the drawings
This specification includes such as next width accompanying drawing：
Fig. 1 is a kind of schematic cross-sectional view of anchoring type reinforcement structure of the utility model.
Component name and corresponding mark are shown in figure：Friction pile 1, grappling key 2, anchor cable 3, backfill body 4, sliding surface A.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
Reference picture 1, a kind of anchoring type reinforcement structure of the present utility model, including the friction pile being arranged in slip mass
1, the inner side position of slip surface of the friction pile 1 has grappling key 2, and sliding surface A is exposed at the top of grappling key 2.The outside of anchor cable 3 is fixed on antiskid
The top of stake 1, inner side is connected with grappling key 2.Backfill body 4 is backfilled in the construction retaining wall at the top of grappling key 2.
The utility model resists Thrust of Landslide using anchor pile 1, with the less cantilever segment of grappling key 2 and larger anchoring
Section, larger favourable anchoring pulling force can be provided by the tensioning of anchor cable 3 effect for friction pile 1, thus optimize friction pile 1 by
Power performance, greatly enhances the anti-slide performance of friction pile 1, and largely saves construction investment, while grappling key 2 is used as anchor cable
3 inner side anchor point, solves the technologies such as the anchor force that poor Rock soil Foundation stream line 3 provides is small, long durability is not enough
Problem.The anchor force of grappling key 2 is passed to reinforcing pile 1 using anchor cable 3, anchor cable 3 plays pulling force transmission, and it can be provided most
Big value of thrust is controlled by grappling key 2, and because grappling key 2 has stronger tensile capacity, therefore the value of thrust that anchor cable 3 is provided is larger simultaneously
And it is adjustable.It is hollow with the top retaining wall for backfilling the closure construction grappling key 2 of body 4, it is to avoid to be oozed under surface water.
The structure efficiently solves the landslide reinforcement technical barrier on the poor Rock soil Foundation of subgrade reaction, with construction
Difficulty is small, structure durability is good, good economy performance the features such as, with wide popularizing application prospect.
Reference picture 1, the friction pile 1 is generally located on slip mass leading edge antiskid section, when pouring pile body armored concrete
Reserve anchor cable hole in top.The distance of the grappling key 2 and friction pile is according to anchor cable 3 and the determination of the angle of horizontal direction, angle one
As be 15-30 degree, it highly is 1-3m that sliding surface A is exposed at its top, is embedded to below sliding surface A depth not less than 4m.
The sequence of construction of the structure is：Merogenesis excavates friction pile stake well, and merogenesis carries out stake well and gone along with sb. to guard him, and is recycled to friction pile
Stake bottom elevation → placing reinforced concrete anti-slide pile, anchor cable hole → treat that friction pile intensity reaches design strength is reserved in stake top
After 80%, merogenesis excavates grappling key construction hole, and merogenesis carries out hole wall and gone along with sb. to guard him, and is recycled to grappling key Bottom Altitude → from friction pile
Constructed in the preformed hole of top to grappling key position and anchor cable hole and be put into stretch-draw anchor → colligation grappling key steel reinforcement cage, steel reinforcement cage and anchor
Rope is fixedly connected with → poured grappling key concrete → backfill grappling key top portion backfills body → and treats that anchor cable bond strength reaches design strength
90% after, stretch-draw anchor meet design stretching force simultaneously anchor cable end socket is locked.
Some the of the present utility model principles described above that simply explain through diagrams, are not intended to the utility model being confined to
In shown and described concrete structure and the scope of application, therefore every corresponding modification for being possible to be utilized and equivalent,
Belong to the apllied the scope of the claims of the utility model.
