Description
Technical field
The invention belongs to geotechnical engineering fields, are related to a kind of suspension roof support structure and its construction method that can be recycled completely,
Suitable for Soft Rock Area.
Background technology
Anchorage technology is because of its economic security, construction is fast, the advantages such as small are disturbed to country rock, as in China's anchoring engineering
One of most common technological means.Anchor pole is suitable for the anchoring of all kinds of underground engineerings and all kinds of side slopes etc..Anchor pole is divided into permanently
Property and two provisional classes.Permanent anchor pole is generally more demanding to anchor-holding force of anchor bolt.For temporary work, if still used
Permanent anchor pole will certainly cause the wasting of resources;Meanwhile if in city, a large amount of anchor poles are embedded in underground, are applied to subsequent
Work, the excavation of foundation pit in adjacent plot, subway work, city long-term plan are likely to have an impact.In view of the above-mentioned problems, it can return
Half davit comes into being.
Existing recoverable anchor rod can be divided into three categories rotary type according to the principle of recycling, tear anchor type open, hale failure type three
Class.The making of rotary type recoverable anchor rod is simpler, and recycling is more convenient, and recycling pulling force is smaller, and bearing capacity is higher, but its cost mistake
Height, post processing is complicated, is not easy to recycle, and easily fails.Although tearing anchor type recoverable anchor rod stress stage stabilization open, pulling force is recycled
It is small but very high to equipment requirement during its recycling.It may make anchor when it is higher to hale failure type recoverable anchor rod bearing capacity, but recycling
Bar is damaged, and higher to equipment requirement during recycling, does not apply to the application in small space.Moreover, recyclable anchor of the prior art
Also there are following defect and deficiencies for bar:(1) installation is complicated, and traditional installation tool is difficult to realize installation, it is necessary to be equipped with dedicated
Installation machinery;(2) special equipment is needed when some recoverable anchor rods recycle, the rate of recovery is low;(3) it is of the prior art recyclable
Recycling in anchor pole and non-fully meaning, still has partial component to residue in Rock And Soil after recycling;(4) it is of the prior art to return
The half davit overwhelming majority still needs to slip casting maintenance, consumes long in time limit.
The content of the invention
To solve the above problems, the present invention provides a kind of suspension roof support structure and its construction method that can be recycled completely, knot

Plate and cover board are by pre-manufactured hole with bar dowel split.
Driving cog is arranged in parallel with card slot.
Center mutual central symmetry of two loading plates on gear, center mutual center pair of two convex clips on bottom plate
Claim.
(cover board and bottom plate be subject to Rock And Soil due to being frictionally secured to ground by the rotation of anchor pole drive transmission shaft by the present invention
In body) make mutual centrosymmetric card slot in the opposite direction or the movement of opposite direction, realize mutually centrosymmetric carrying
The expansion and gathering of plate, while effectively prevent loading plate and completely disengaged with bottom plate.
The anchor pole and prefabricated end socket are connected by bolt or be welded and fixed.
It is preferred that the lower end of the main shaft of transmission shaft is equipped with screw thread, welded nut prevents transmission shaft from being separated with bottom plate on screw thread.
Further, for convenience of the expansion and gathering of loading plate, convex clip width is the 80%~90% of card slot width, thickness
To carry 1.2~1.3 times of plate thickness.
Further, to meet the thickness that the requirement of bearing capacity can suitably thicken cover board, loading plate and bottom plate, thickness of slab is carried
Bottom plate convex clip thickness accordingly increases or adds one or a few cover board in cover board and plate outer side or lengthen connection after degree increases
The bar dowel of bottom plate and cover board is simultaneously respectively connected with an anchor pole stretching out cover board one end.
The present invention also provides a kind of construction methods for the suspension roof support structure that can be recycled completely, comprise the following steps:
A. drill
Anchor hole is drilled through, prefabricated end socket width (width when loading plate collapses) is slightly larger than according to design requirement anchor hole diameter,
Expansion processing is done in anchor hole bottom, and the diameter after expansion is not less than width of the prefabricated end socket after loading plate is fully deployed, and anchor hole is applied
