Detailed description of the invention
Please refer to Fig. 1 and Fig. 2, a kind of pressure dissipation U-shaped recovery anchor cable supporting body, comprise two holders 10 and four dowel bars 20, arrange before and after these two holders 10.Each holder 10 comprises a circular loaded plate 11 and a semicircular fixed head 12, this loaded plate 11 and fixed head 12 are all steel plate, the circular radius of this loaded plate 11 is equal with the semicircle radius of fixed head 12, this fixed head 12 has an arc surface, a string face (face along Axis Extension string) and two end faces arranged dorsad, this loaded plate 11 has the end face arranged dorsad on a face of cylinder and two, the string face of this fixed head 12 is fixed in the front end face of loaded plate 11, and this fixed head 12 is fixed in loaded plate 11 along the radial arrangement of loaded plate 11.
The arcwall face of this fixed head 12 is arranged with the arc other end that extends to arcwall face from arc one end of arcwall face and cross section is the first groove 121 of U-shaped, and this loaded plate 11 surface of revolution is arranged with two radial symmetric and runs through loaded plate 11 both ends of the surface and cross section is the second groove 111 of U-shaped.Wherein: the two-port alignment of these two the second groove 111 respectively with the first grooves 121 of first holder 10, relative first groove 121 of these two the second grooves 111 of second holder 10 is arranged symmetrically with.
These many dowel bars 20 are all vertically fixed between the loaded plate 11 of two holders 10, in concrete structure: this dowel bar 20 front end is fixed in the rear end face that is positioned at the loaded plate 11 of the holder 10 of front side, this dowel bar 20 rear end is fixed in the front end face that is positioned at the loaded plate 11 of the holder 10 of rear side.And the first groove 121 of these two holders 10 aligns, and the fixed head 12 of two holders is arranged vertically.Among the present embodiment, this dowel bar 20 is indented bars, and these four dowel bars 20 are arranged along the axis circumferential array of loaded plate 11.
This loaded plate 11 establishes one to run through loaded plate 11 both ends of the surface and the manhole 112 of dead in line loaded plate 11 axis; The axial location in the string face of this fixed head 12 is recessed always wears the both ends of the surface of fixed head 12 and dead in line fixed head 12 axis and cross section is semicircular 3rd groove 122,3rd groove 122 opening is greater than and surrounds manhole 112 port, and the radius of the 3rd groove 122 is greater than the radius of manhole 112.
Among the present embodiment, this first holder 10 is front, and this second holder 10 is rear.
Dowel bar can stretch into bearing plate rear, the pressure dissipation of supporting body can be transmitted in the longer one section of slurry in bearing plate rear, because dowel bar is to the peptizaiton of pressure-bearing load, greatly reduce the compressive stress of loaded plate to loaded plate near-end injecting cement paste, thus avoid causing the excessive phenomenon even destroyed of distortion because loaded plate near-end slurry pressurized is excessive, and then the construction requirement reduced bearing plate rear injecting cement paste, quality easily ensures, thus guarantee the stable of whole anchor cable quality, guarantee engineering safety.
Among another preferred embodiment: it and a upper preferred embodiment difference are: this second holder 10 is front, and this first holder 10 is rear.
The above, be only the utility model preferred embodiment, therefore the scope that the utility model implements can not be limited according to this, the equivalence namely done according to the utility model the scope of the claims and description change with modify, all should still belong in scope that the utility model contains.
