Description
Technical field
The utility model is related to a kind of ruggedized constructions of embedded prestress anchorage cable, belong to hydraulic and hydroelectric engineering technology neck
Domain.
Background technology
In hydraulic and hydroelectric engineering process of construction, can usually encounter a large amount of, complicated rock mass engineering project structure, as side slope,
Lower cavern, road（Dam）Base, deep basal pit etc..The stability of this part Rock And Soil, it is most important for the safety of construction, because
This is generally required in the case that Rock-soil Mass Structure stability is unsatisfactory for requiring or security and stability deposit is not high by adding
Gu to improve stability.Common reinforcement means mainly has：Retaining structure, anchor cable（Bar）, anchor caverns etc..However, if adding
It cannot accomplish adaptation to local conditions in fixed meter and construction, then can cause because reinforcement technique itself is there are many insufficient or misapplications
Consolidation effect is undesirable, even results in the generation of engineering accident.Presently, how under the conditions of space is limited, reasonably
Reinforcement measure is set, not only can guarantee enough reinforcement edges, but also does not influence arrangement or the function use of other buildings, is urgently
A problem to be solved.
Utility model content
The purpose of the utility model is to provide a kind of embedded prestress anchorage cables simple in structure, easy for construction
Ruggedized construction, can effectively provide anchor force under the conditions of arrangement space is limited, it is ensured that stable structure, while not shadow again
It rings building arrangement and function uses, to overcome the deficiencies in the prior art.
What the technical solution of the utility model was realized in：
A kind of ruggedized construction of the embedded prestress anchorage cable of the utility model, including the anchor cable of reinforcement edge is provided；Anchor cable
The anchor pier for providing support force with early period through anchorage is connect, and anchor plate is lined between anchorage and anchor pier, two have been poured outside anchor pier
Phase concrete；Connection is poured using dabbing between second stage concrete and anchor pier.
In the ruggedized construction of aforementioned embedded prestress anchorage cable, the anchorage is OVM anchors.
In the ruggedized construction of aforementioned embedded prestress anchorage cable, the anchor plate is galvanized steel plain sheet, and thickness is not less than 20mm.
In the ruggedized construction of aforementioned embedded prestress anchorage cable, the anchor cable be high intensity, low-relaxation prestressed steel wire or
Steel strand wires, surface galvanized anticorrosive.
In the ruggedized construction of aforementioned embedded prestress anchorage cable, the anchor pier is truncated rectangular pyramids shaped steel tendon concrete structure, by force
Degree is not less than C30.
By adopting the above-described technical solution, the utility model is compared with prior art, the utility model is simple in structure, applies
Work is convenient, by fist stage concrete anchor pier pressure-bearing, after carrying out anchorage cable stretching construction using anchorage, by second stage concrete with positioned at should
The tensioning component at anchor pier position pours together, and anchor pier is made to melt as entirety with second stage concrete；Not only anchoring effect is played, but also is not influenced
Construction appearance and function use.Anchor cable reinforcement measure can effectively be combined cloth by the utility model with fabric structure
It sets, to save anchor cable arrangement space, while playing respective function again and not interfering.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
In figure：1- second stage concretes, 2- anchorages, 3- anchor plates, 4- anchor cables, 5- anchor piers.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and examples, but not as new to this practicality
Any restrictions of type.
The utility model is constituted according to a kind of reinforcement means of following embedded prestress anchorage cables, and this method is such as
Shown in Fig. 1, reinforced according to the following steps：
Step 1: according to structure arrangement and Design of Reinforcement requirement, anchor cable drilling is carried out first, is targetedly made before drilling
Determine deviation controlling and corrective action；Hole wall cleaning is carried out after pore-forming in time；
Step 2: installation anchor cable；Anchor cable hole should be checked before installation, anchor cable lashing should use rubber cushion isolation, support
Transient mode, it is ensured that anchor cable keeps smooth-going in anchor cable hole；
Step 3: duct grouting；Anchor cable grouting is in the milk using orifice closure, or using blind hole or with plasma resistance plug
Method grouting；
Step 4: anchor pier makes；Armored concrete anchor pier is carried out according to design and code requirement to pour；
Step 5: anchorage cable stretching；Pre- tensioning is carried out by 20% design stretching force before formal tensioning, stretching force should be classified and apply
Add, increases to ultra stretching load step by step；
Step 6: structural concrete pours；Wait for that anchor cable construction is completed, after carrying out dabbing processing to anchor pier outer surface, according to
Structural Design Requirement carries out second stage concrete outside anchor pier and pours.Second stage concrete is reinforced concrete structure, second stage concrete
Interior is configured by reinforcing bar by structural requirement.
According to a kind of ruggedized construction of embedded prestress anchorage cable of the utility model of above method composition, including provide
The anchor cable 4 of reinforcement edge；The anchor pier 5 that anchor cable 4 provides support force through anchorage 2 with early period is connect, and is lined between anchorage 2 and anchor pier 5
Anchor plate 3 has poured second stage concrete 1 outside anchor pier 5；Connection is poured using dabbing between second stage concrete 1 and anchor pier 5.Anchor
Tool 2 is OVM anchors.Anchor plate 3 is galvanized steel plain sheet, and thickness is not less than 20mm.Anchor cable 4 be high intensity, low-relaxation prestressed steel wire or
