Description
Technical field
Pattern foundation pit supporting structure, side slope protection, underground engineering advance support technical field are the utility model is related to, more particularly to it is a kind of
Variable cross-section suspension roof support structure.
Background technology
Soil anchor is derived from rock bolting, and the latter is used for underground engineering tunnel excavation supporting very early,
Until later 1950s, De Yuan Bauer companies are just applied to deep foundation pit support first.
One end of soil bolt is coupled with earth-retaining piling wall or engineering structure, and the other end is anchored in soil layer or rock stratum, with
The tilt power of works, buoyancy, bearing down are born, the soil lateral pressure and water pressure of the soil body, it is the anchoring using stratum
Power ensures the safety of structure and deformation requirements.
Due to being limited by construction technology, plant equipment etc., conventional anchor shape is essentially uiform section cylinder, anchor
Bar withdrawal resistance is only provided by the frictional force of induration and the soil body, and it underuses the shearing strength of the soil body, causes anchor pole
Anti-pulling capacity is smaller, and when suspension roof support structure is used particularly in argillic horizon, its effect is not notable.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of larger variable cross-section anchor of anti-pulling capacity
Bar supporting construction.
Variable cross-section suspension roof support structure of the present utility model, including anchor head plate, reinforcing body and induration, the reinforcing body
The anchor head plate is vertically fixed in bottom, and the outside of the reinforcing body is the induration, and the external diameter of the induration bottom is more than
The external diameter on top.
Further, the reinforcing body is steel strand wires.
Further, the anchor head plate is connected including at least two panels anchor head connection sheet, the anchor head connection sheet by rotating shaft.
Further, the induration is the concretionary cement induration of slip casting.
Further, the external diameter of the induration is tapered into by bottom to top.
Further, the longitudinal cross-section of the induration is to be arranged in stair-stepping multi layer consolidation split.
Further, the junction between the multi layer consolidation split is inclined-plane.
By such scheme, the utility model at least has advantages below：
1st, the force-transmission mechanism between anchor pole and soil layer or rock stratum is greatly changed, oneself of the soil body or ground can be made full use of
Weight effect and shearing strength；
2nd, anti-pulling capacity is big compared with conventional anchor by 300%, when coordinate foldable anchor head plate in use, its anti-pulling capacity compared with
Conventional anchor increase 400%；
3rd, suitable soil layer scope is wide, cannot be only used for mountain area rock mass, also acts as permanent supporting construction；
4th, when it applies to City Excavation Engineering supporting, and its rock-bolt length influences periphery new building, reverse remove is applied
The more general anchor pole of work is convenient.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of specification, with preferred embodiment of the present utility model and coordinate accompanying drawing detailed below
Describe in detail bright as after.
Brief description of the drawings
Fig. 1 is the longitudinal sectional view of taper variable cross-section anchor pole in the utility model；
Fig. 2 is the longitudinal sectional view of stairstepping variable cross-section anchor pole in the utility model；
Fig. 3 is the longitudinal sectional view of bevel-type stairstepping variable cross-section anchor pole in the utility model；
Fig. 4 is the structural representation of reaming drill bit in the utility model.
Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not limited to the scope of the utility model.
Embodiment one
Referring to Fig. 1 to Fig. 3, a kind of variable cross-section suspension roof support structure of the preferred embodiment of the utility model one, including anchor head
Anchor head plate is vertically fixed in plate 3, reinforcing body 2 and induration 1, the bottom of reinforcing body, induration be fastened around reinforcing body outside,
And the bottom of induration interfixes with anchor head plate, the external diameter of induration bottom is more than the external diameter on top.
A kind of variable cross-section suspension roof support structure of the present utility model, reinforcing body is steel strand wires；Anchor head plate includes at least two panels
Anchor head connection sheet, anchor head connection sheet are connected by rotating shaft；Induration is the concretionary cement induration of slip casting.
A kind of variable cross-section suspension roof support structure of the present utility model, there can be at least three kinds of embodiments, including such as Fig. 1 institutes
The taper variable cross-section anchor pole shown, the i.e. external diameter of induration are tapered into by bottom to top；Including ladder deformation as shown in Figure 2
The longitudinal cross-section of section anchor pole, i.e. induration is to be arranged in stair-stepping multi layer consolidation split；Including bevel-type rank as shown in Figure 3
Trapezoidal variable cross-section anchor pole, i.e., on the basis of Fig. 2, the junction between multi layer consolidation split is inclined-plane.
Embodiment two
The utility model provides a kind of mounting process of variable cross-section suspension roof support structure, comprises the following steps：
As shown in figure 4, before pore-forming, first the one end of reinforcing body 2 is coupled with foldable anchor head plate 3, the foldable anchor head plate 3
Reaming bit 6 after closing up again with reaming rig is linked；
Rotated by the drilling rod 4 on reaming rig and promote reaming bit 6 to enter underground layer or rock stratum, this process utilizes mud
Retaining wall is carried out, then controls hydraulic pressure transmission rod 5, amplitude modulation is carried out to reaming bit 6, ultimately forms variable cross-section hole；
When reaming bit 6 reaches design attitude, drilling rod is reversely rotated, reaming bit 6 separates with foldable anchor head plate 3,
Now foldable anchor head plate is opened, and then slowly exits reaming bit 6, and startup high-pressure rotary-spray equipment, utilizes nozzle during this
7, rotary jet grouting is carried out to variable cross-section hole, ultimately forms variable cross-section anchor pole.
Described above is only preferred embodiment of the present utility model, is not limited to the utility model, it is noted that
For those skilled in the art, on the premise of the utility model technical principle is not departed from, can also do
Go out some improvement and modification, these improvement and modification also should be regarded as the scope of protection of the utility model.
