Description
Technical field
This utility model belongs to reinforcing and the supporting field of soft rock-soil, is specifically related to a kind of soft rock-soil height withdrawal resistance anchoring dress
Put.
Background technology
In the civil engineering such as traffic, water conservancy, the conventional anchor such as grouting rock bolt or grouted anchor bar is to tunnel, side slope
In soft rock-soil reinforce.Anchorage Technology is by one tension member embedment stratum, to improve ground from stiffness of the body
Degree and a kind of engineering of self-stable ability, owing to this technology significantly alleviates the deadweight of works, saves engineering material, and
Guarantee the safety of engineering and consolidate, there is significant economic benefit and social benefit, be therefore 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 keeps stratum
The homeostasis of excavation face, it can provide and act on works to bear the drag of outer lotus, can make works and stratum
It is bound up, forms a kind of cooperative complex so that it is can effectively bear pulling force and shearing.In engineering practice
The bearing capacity of anchor pole rely primarily on shank member particularly anchoring section and around cohere frictional force between rock soil medium.Prior art
The anchoring section used is straight line structure, and often frictional force is limited, particularly at Impact direction with anchor pole angular separation relatively
In the case of little, if run into soil layer cohere frictional strength relatively low time, often be difficult to meet design withdrawal resistance requirement.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, weak for the engineering structure such as tunnel, side slope
The reinforcing of ground and the anchor that supporting provides a kind of high withdrawal resistance, grouting consolidation effect is good, anchorage effect is strong.
The technical solution adopted in the utility model is: a kind of soft rock-soil height withdrawal resistance anchor, including slip casting conical head,
Abnormity grouted anchor bar, cross fastening frame;Described abnormity grouted anchor bar is hollow pipe;Described slip casting conical head one end is solid-cone
Shape head, other end inner hollow is also connected with abnormity grouted anchor bar;Described cross fastening frame is installed on described abnormity grouted anchor bar
One end, middle part is in the form of annular discs.
