Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, to the static sounding counterforce device detailed description of the invention containing Reducing screw line earth anchor and afterburning dish, structure, feature and effect thereof of proposing according to the present invention, be described in detail as follows.
See Fig. 1 to Fig. 7, of the present invention containing Reducing screw line earth anchor and the afterburning static sounding counterforce device coiled, comprise earth anchor 2, afterburning dish 9, wherein: earth anchor 2 is contained between frame supporting leg 4, be provided with bottom earth anchor 2 and creep into 1, Reducing screw line blade 3 is connected to and creeps into head (1) top, earth anchor 2 top is provided with thread segment 7, thread segment 7 top is connected with snib 8, earth anchor foundary weight 5 is contained in above the Reducing screw line blade 3 of earth anchor 2, earth anchor foundary weight 5 two ends are placed on frame supporting leg 4, the thread segment 7 of earth anchor 2 is equipped with earth anchor nut 6, earth anchor nut 6 is pressed together on above earth anchor foundary weight 5, earth anchor 2 is supporting afterburning dish 9, and the draw-in groove 10 that afterburning dish 9 is arranged by middle part matches with the snib 8 on earth anchor 2 top.Creep into 1 in turbination.Earth anchor 2 is two covers.Reducing screw line blade 3 is welded on earth anchor 2 in back taper.Earth anchor foundary weight 5 cross section is inverted concave, and its plane side upwards.Snib 8 cross section is square.Draw-in groove 10 is the square groove matched with snib 8 in cross section.
During use, see Fig. 8, first, determine the putting position of static sounding frame according to the position of test point, the region between frame supporting leg 4, after determining the position of two earth anchors 2 separately, frame is removed.In the position of earth anchor 2, before creeping into, first can dig the dark V-type groove of 10 ~ 20cm, so as better ensure earth anchor 2 straight down initially pierce direction.
Second step, according to soil layer 11 proterties, after the earth anchor model that soil layer 11 thickness and the counter-force size needed for static sounding select suitable bar long, earth anchor 2 is positioned over the position needing to creep into, manually by its righting, extremely (Reducing screw line blade 3 is downward straight down, square snib 8 upwards), then after reinforcing dish 9 being withheld with the square snib 8 at earth anchor 2 top by the square draw-in groove 10 of its center, reinforcing dish 9 turns clockwise by artificial reinforcing, earth anchor 2 is rotated down pierce, stop creeping in time being drilled into the lower boundary distance ground 10 ~ 20cm of earth anchor 2 screw top section 7, finally reinforcing dish 9 is separated after taking off with earth anchor 2, reinforcing dish 9 is placed on one side after being crept into by another earth anchor 2 and putting in place by method according to this.
After two earth anchors 2 pierce and put in place, frame supporting leg 4 is made to be placed in the both sides of two earth anchors 2 respectively, then two earth anchor foundary weight 5 are respectively by after the circular hole at its center, through two earth anchor 2 tops of both sides, with the direction perpendicular to frame supporting leg 4, earth anchor foundary weight 5 is placed on (the plane side of earth anchor foundary weight 5 upwards) on frame supporting leg 4.
Subsequently earth anchor nut 6 is rotated by the screw thread of its inside the thread segment 7 being inserted in two earth anchor 2 tops separately respectively, and press above earth anchor foundary weight 5 and fix earth anchor foundary weight 5, and then control rocking of whole frame, and after making the counter-force of earth anchor 2 pass to earth anchor foundary weight 5 by earth anchor nut 6, pass to frame again by earth anchor foundary weight 5.So far, a whole set of counterforce device is in place, and can carry out static sounding test.
Finally, after static sounding has been tested, earth anchor nut 6 is rotated and takes off, and earth anchor foundary weight 5 is taken off from earth anchor 2, then static sounding frame is removed, then use afterburning dish 9 to be rotated counterclockwise and to be taken out by earth anchor 2 in the same way with after snib 8 buckle of earth anchor 2.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, anyly do not depart from technical solution of the present invention content, the any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
