Abstract
The utility model relates to a kind of off-load corrosion area tunnel anchorage with antiskid key, a kind of off-load corrosion area tunnel anchorage with antiskid key, including anchor body, pommel room and rear saddle room are provided with the antiskid key of evagination on the downside of anchor body bottom.The utility model preferably resolves the problem of off-load corrosion area tunnel anchorage anchor body need to carry out extensive karst cave treatment, anchor body breakout capacity can be effectively increased, with save engineering material, construct convenient, low cost, short time limit, it is applied widely, mechanical property is good the features such as.
Description
Technical field
It is molten more specifically to a kind of off-load with antiskid key the utility model relates to off-load corrosion area tunnel anchorage
Lose area's tunnel anchorage.
Background technique
Currently, having built a large amount of suspension bridge projects, suspension bridge in great rivers with the fast development of economic construction of China
Anchor system generallys use gravity anchor and bridge anchorage, as a kind of relatively new bridge bearing structure, tunnel anchorage compared with
Gravity anchor has significant economic advantages, by more and more extensive use.Some projects are in karsts developing area region, due to rock mass structure
Concealment, uncertainty and Spatial-Temporal Variability, during the design are difficult to verify solution cavity distribution situation completely, therefore the later period is commonly present need
Anchor body exception processes are lengthened, but lengthens anchor body and brings a series of problems, such as project amount is big, economy is poor, constructional difficulties.
Utility model content
The technical problem to be solved by the present invention is to providing a kind of can effectively improve anchor body withdrawal resistance, and engineering
Measure the off-load corrosion area tunnel anchorage that small, good economy performance, simple structure, construction easily have antiskid key.
The technical scheme adopted by the utility model to solve the technical problem is as follows: it is molten to construct a kind of off-load with antiskid key
Area's tunnel anchorage, including anchor body, pommel room and rear saddle room are lost, the antiskid key of evagination is provided on the downside of anchor body bottom.
According to the above scheme, the antiskid key is made of the impervious armored concrete of C30 microdilatancy polypropylene fibre, described anti-
Feather key pouring molding together with anchor body.
According to the above scheme, chamfering is set between the antiskid key and anchor body.
According to the above scheme, the antiskid key height h is not less than the 1/6 of institute's anchor body height H.
According to the above scheme, the antiskid key length L is 2 times of antiskid key height h.
According to the above scheme, the antiskid key and anchor body is of same size.
The off-load corrosion area tunnel anchorage with antiskid key for implementing the utility model, has the advantages that
Compared to more past corrosion area, need to lengthen anchor body, project amount is big, and economical difference, construction period is long, and lengthens anchor
Know from experience and new geological problem occur, the utility model can increase withdrawal resistance using antiskid key, can evade above-mentioned a series of ask
Topic.The utility model project amount is small, good economy performance, simple structure, construction are convenient, reduces project cost.
Detailed description of the invention
Below in conjunction with accompanying drawings and embodiments, the utility model is described in further detail, in attached drawing:
Fig. 1 is the structural schematic diagram of off-load corrosion area tunnel anchorage of the utility model with antiskid key.
Specific embodiment
For a clearer understanding of the technical features, objectives and effects of the utility model, now control attached drawing is detailed
Illustrate specific embodiment of the present utility model.
As shown in Figure 1, the off-load corrosion area tunnel anchorage with antiskid key of the utility model includes anchor body 1,2 and of pommel room
Saddle room 3 afterwards.
The antiskid key 4 of evagination is provided on the downside of the bottom of anchor body 1, antiskid key 4 is using C30 microdilatancy polypropylene fibre
Impervious armored concrete, when pouring with anchor body 1 together pouring molding.Chamfering is set between antiskid key 4 and anchor body 1, to disappear
Except the concentration of local stress, increase fastness.4 height h of antiskid key is not less than the 1/6 of 1 height H of anchor body.4 length L of antiskid key is set
It is set to 2 times of 4 height h of antiskid key.The width of antiskid key 4 is of same size with anchor body 1.
The embodiments of the present invention are described above in conjunction with attached drawing, but the utility model is not limited to
The specific embodiment stated, the above mentioned embodiment is only schematical, rather than restrictive, this field it is common
Technical staff is not departing from the utility model aims and scope of the claimed protection situation under the enlightenment of the utility model
Under, many forms can be also made, these are belonged within the protection of the utility model.
