Description
Technical field
The utility model relates to the supporting and protection structure field in rock tunnel engineering field, is specially a kind of detachable firmware that is applicable to the large and rock stratum that quality is soft of brokenness.
Background technology
Increasing along with the development of economic construction and road construction correlation engineering, often need to carry out safety support in case rock-soil layer becomes flexible, comes off to soil layer and rock stratum.And in the supporting and protection structure of rock-soil layer, conventionally need to use support anchor rod this weak rocks soil layer is reinforced and supporting.Cement paste is become to mixture with soft rock-soil jet mixing, and insert dowel formation anchor structure, so that broken rock-soil layer anchoring is become to overall structure, can fully increase the self-supporting ability of weak rocks soil layer, greatly reduce support material cost, and shorten the construction period.
Yet, in some weak rocks soil layers, build underground installation, loose crushing due to rock-soil system, make their strength and stability of self very poor, and traditional anchor type conventionally can only act in dryness rock stratum that some brokennesses are less, the rock-soil layer that large for some brokennesses and quality is soft and is easy to produce slippage, lose anchorage effect.And if adopt some ruggedized constructions to carry out the reinforcing of anchor type, often have and can when construction completes, occur the situation that anchoring body cannot be removed, cause obstacle to the building operations of subsequent job, if remove by force disturbance and the destruction that also easily occurs existing rock-steady structure, thereby applicability bad.
Utility model content
The technical problem that the utility model solves is to provide a kind of detachable anchoring piece, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of detachable anchoring piece, comprise anchor pole, support, backplate and cushion block, wherein, cushion block is positioned at support, backplate is positioned at cushion block bottom, backplate and cushion block are all provided with the through hole of vertical direction in centre position, described support comprises substrate and is inserted into substrate both sides and through two backstays of substrate, and described anchor pole is fixed on support centre position, comprise the body of rod, protective metal shell and maintenance piece, the body of rod passes cushion block and backplate by through hole, protective metal shell and maintenance piece are sleeved on lever front end, described protective metal shell inner side is provided with and has internal thread, and the correspondence position of anchor pole has corresponding with it external screw thread, described maintenance piece top is separated with protective metal shell, and being threaded connection mode with anchor pole fixes.
In the utility model, described backstay front end is provided with cylindricality rubber cushion blocks, and it is spacing so that it is assisted by this rubber cushion blocks, to withstand backing plate.
In the utility model, between described support and cushion block, be provided with reinforcement pad, and strengthening by an annular gasket, providing buffering and decompression between pad and cushion block.
In the utility model, the cross section of described protective metal shell is quadrangle or regular hexagon structure, and has on its outer surface anti-skid design, in order to prevent that skidding occurs when assembling.
In the utility model, the wall thickness of described protective metal shell is 30-50mm; Length is 200 ~ 400mm.
Beneficial effect: the utility model compact conformation, reasonable in design, in assembling work progress, whole boring all fits tightly with anchor pole face, coordinates maintenance piece can reach the fixed object of full anchoring, and any loosening disengaging can not occur; After having constructed, can carry out easily support recovery, during recovery, whole of anchor pole can be pulled out and do not affect its intensity, and can facilitate secondary anchoring.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model preferred embodiment.
Wherein: 1, bolt; 2, stent substrate; 3, strengthen pad; 4, anchor pole; 5, annular gasket; 6, backstay; 7, cushion block; 8, cylindricality rubber cushion blocks; 9, protective metal shell; 10, backplate; 11, maintenance piece; 12, the rock-soil layer of concrete strengthening.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Preferred embodiment referring to a kind of detachable anchoring piece of Fig. 1, in the present embodiment, detachable anchoring piece is as the fixture of the footing of Soft rock layer, its agent structure is a supporting structure, this supporting structure top is stent substrate 2, stent substrate 2 both sides are provided with two backstays 6, backstay 6 tops are through stent substrate 2 fixing by bolt 1, bottom connects cylindricality rubber cushion blocks 8, and in stent substrate 2 centre positions, be fixed with an anchor pole 4, this anchor pole 4 is through strengthening pad 3, annular gasket 5, cushion block 7, and in its underpart, to be provided with a wall thickness be 40mm, length is protective metal shell 9 and a maintenance piece 11 of 400mm.
The detachable anchoring piece of the present embodiment is when assembling, by in the rock-soil layer 12 of the protective metal shell 9 of anchor pole 4 ends and the 11 Transducers Embedded in Concretes reinforcings of maintenance piece, and the upper surface of protective metal shell 9 is exposed, its top is undertaken spacing by backplate 10, by the bolt 1 on two backstay 6 tops of turn, adjust rock-soil layer 12 degree of compaction and the position of concrete strengthening, then keep completing moulding.After moulding, unscrew the bolt 1 on two backstay 6 tops, a moment of torsion is provided on backstay 6, because the cross section of protective metal shell 9 is quadrangle, and have on its outer surface anti-skid design, can anchor pole 4 back-out protective metal shells 9 and maintenance piece 11 be completed to recovery by minimum destructive power, in the rock-soil layer 12 that protective metal shell 9 together with being molded over the rock-soil layer 12 of concrete strengthening and maintenance piece 11 are stayed concrete strengthening, can effectively guarantee the intensity of the rock-soil layer 12 of concrete strengthening on the one hand, simultaneously, the inner threaded surface of protective metal shell 9 is still available, can effectively facilitate the built-in fitting as secondary anchoring piece to use.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and manual, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
