Abstract
The invention discloses a yielding type backing plate device which comprises first channel steel and second channel steel; the first channel steel is reversely buckled on the second channel steel tightly to form into a cavity; a spring is arranged inside the cavity; two ends of the spring are respectively arranged on two groove faces of the first channel steel and the second channel steel; a footing of the first channel steel and a groove face of the second steel are not contacted with each other; and the groove faces of the first channel steel and the second channel steel are provided with round holes. The yielding type backing plate device has the advantages of being simple in structure and convenient to use, enabling a supported rock and soil layer to generate certain deformation, achieving combination that firstly yielding is firstly performed and supporting is then performed without matching of other installation programs, being capable of well handling the problems of large deformation and high stress of a rock and soil layer support with large stress and enabling the same type rock and soil layer to be stable and reliable due to the facts that the yielding type backing plate is formed by the two channel steel which are assembled in a reverse buckling mode and the high strength spring which is arranged between the two channel steel and the yielding type backing plate is tightly locked on an anchor rod (cable) when construction is performed.
Description
Technical field
The invention belongs to engineering construction and application, particularly the roadway bolt used of a kind of mine or the allowed die mould pallet device of anchor cable.
Background technology
Country rock refer to the rock mass around the tunnel of excavating, be the stable influential rock mass to tunnel itself strictly; Anchor pole is surface, the corresponding tunnel of an end, the corresponding roadway surrounding rock deep layer of other end rock mass, and integral body is in the Metallic rod in the rock-soil layer, and the prestress wire of anchor cable to be integral body pass rock-soil layer slide surface.Backing plate is for anchor pole (rope) applies the metal sheet that prestressing force and surface, tunnel are close to, and has circular hole to pass through for anchor (bar) rope above.
At present, in roadway and geotechnical engineering prestressed anchor (bar) the rope supporting construction, be after anchor (bar) rope is goed deep into rock-soil layer inside, overlapped the end on the protruding dew of anchor (bar) rope and rock-soil layer surface with backing plate, after utilize lockset that anchor pole (rope) is applied certain prestressing force.This method compliance in the less rock-soil layer of ground pressure is strong, along with the development of present geotechnical engineering to farther direction, high strength, deformable anchor (bar) rope pallet device are urgently by demand, in the big rock-soil layer of geostatic stress, the rock-soil layer distortion is big, and pressure is big.Carry out the supporting of anchor (bar) rope if only simply apply prestressing force, certainly lead to very big stress when the rock-soil layer distortion surpasses controlled range so, when the prestressing force that applies on anchor (bar) rope is consumed totally, anchor (bar) rope just might be broken by powerful stress, after anchor (bar) rope was broken, its supporting had also just lost meaning.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of allowed die mould simple in structure, esy to use, safe and reliable pallet device.
The technical scheme that the present invention addresses the above problem is: a kind of die mould pallet device that allows, comprise first channel-section steel and second channel-section steel, the tight left-hand thread of described first channel-section steel is on second channel-section steel and form a cavity, is provided with spring in the cavity, and the two ends of spring lay respectively on the groove face of two channel-section steels.
The footing of described first channel-section steel does not contact mutually with the groove face of second channel-section steel.
Have circular port on the groove face of described first channel-section steel and second channel-section steel.
Described first channel-section steel and second channel-section steel are C font channel-section steel.
Beneficial effect of the present invention is: the present invention makes up two channel-section steel left-hand threads, and between two channel-section steels, fold up high-strength spring, so not only simple in structure, easy to use, and in practical work process, can allow rock-soil layer to produce certain controllable deforming, rely on prestressing force and anchor cable self intensity to carry out supporting again after allowing it discharge certain stress earlier.Like this, allow rock-soil layer discharge earlier to carry out positive supporting again behind a part of stress and can well tackle large deformation, the heavily stressed problem that the big rock-soil layer supporting of geostatic stress faces, make that this type of rock-soil layer is reliable and stable.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is construction schematic diagram of the present invention.
Among the figure: 1, first channel-section steel, 2, second channel-section steel, 3, spring, 4, lockset, 5, anchor pole (rope).
The specific embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
As shown in Figure 1, the present invention includes first channel-section steel 1 and second channel-section steel 2, described first channel-section steel, 1 tight left-hand thread is on second channel-section steel 2 and form a cavity, be provided with spring 3 in the cavity, the two ends of spring 3 lay respectively on the groove face of two channel-section steels, the footing of described first channel-section steel 1 does not contact mutually with the groove face of second channel-section steel 2, and described first channel-section steel 1 and second channel-section steel 2 are C font channel-section steel.
As shown in Figure 2, have circular port at the groove face of first channel-section steel 1 and 2 two channel-section steels of second channel-section steel, anchor pole (rope) 5 passes from circular port, and with lockset 4 anchor pole (rope) 5 is locked on first channel-section steel 1.
Implementation process of the present invention is as follows: boring earlier, after guaranteeing that drilling quality is good, anchoring agent powder stick is put into the hole, anchor pole (rope) 5 is with progressively deeply boring thereafter, determine that powder stick arrives at the boring bottom, by anchoring drilling machine power powder stick is stirred, firm to guarantee the anchored end anchoring, load onto first channel-section steel 1, second channel-section steel 2 and the spring 3 that assembles in advance in anchor (bar) rope 5 protruding dew parts, with lockset 4 certain prestressing force is locked and applied to anchor pole (rope) 5 with anchoring drilling machine at last.The present invention has overcome that rock-soil layer can not produce the deficiency that controllable deforming discharges certain stress in anchor pole (rope) 5 supportings in the past, not only simple in structure, easy to use, and can allow the supporting rock-soil layer produce certain deformation, realize allowing earlier and press the back supporting to combine, need not other erection procedures cooperates, like this, allow rock-soil layer discharge earlier to carry out positive supporting again behind a part of stress and can well tackle large deformation, the heavily stressed problem that the big rock-soil layer supporting of geostatic stress faces, make that this type of rock-soil layer is reliable and stable.
