Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments。Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not paying creative work premise, broadly fall into the scope of this utility model protection。
As shown in Fig. 1 ~ 10, a kind of novel umbrella foundation bearing capacity detecting device, including earth anchor 6, column 1 and brace 2, column 1 upper end is connected with brace 2, brace 2 is connected with vertical counter-force pulling seat 3, and the first base 3-1 bottom vertical counter-force pulling seat 3 is arranged in counter-force pressure beam 5, and the second base 6-1 on earth anchor 6 is also disposed in counter-force pressure beam 5, vertical counter-force pulling seat 3 is connected with crossbeam 4, and crossbeam 4 is connected with bottom column 1。
This novel practical adds crossbeam 4 and counter-force pressure beam 5 on the basis of existing cable-stayed type counterforce device, not only makes earth anchor 6 can provide bigger counter-force, and makes device avoid because earth anchor 6 unstable phenomenon is occurred by excessive oblique pulling effect。Additionally, can also according to actual requirement of engineering, at the enterprising windrow weight of crossbeam 4, to provide bigger counter-force, adapt to different testing conditions, simultaneously in whole device, all rod members are all only limited by tension and compression active force, take full advantage of the mechanical characteristic of steel, reduce the quality of whole device, effectively save resource。
Preferably, as shown in Figures 2 and 3, described column 1 includes hollow cylinder 1-1, and hollow cylinder 1-1 top and bottom welding have circular slab 1-2, hollow cylinder 1-1 top and bottom to be respectively welded with four groups of bolts connection key seat 1-3。
The circular slab 1-2 that hollow cylinder 1-1 top and bottom are respectively welded is the active force bearing bottom jack, it addition, for preventing column from rolling when horizontal positioned, it is also possible to it is respectively symmetrically four reinforcing bars of welding in hollow cylinder 1-1 surrounding。
Further, as shown in Figure 4, described brace 2 is included branch sleeve 2-1, branch sleeve 2-1 two ends and is connected with pull bar 2-2 by screw thread, and pull bar 2-2 end is connected key seat 1-3 and is connected with bolt。After so arranging, the length of brace 2 can regulate, it is possible to is effectively ensured the degree of stability of whole device。Brace 2 is divided into four groups, and top is connected by bolt with column 1, and bottom and crossbeam 4 are commonly connected to vertical counter-force pulling seat 3 top, are bolted。
As shown in Figure 8 and Figure 9, counter-force pressure beam 5 is welded by two ends by two U-shaped steel, and space is left in centre, and to facilitate vertical counter-force pulling seat from middle traverse, two ends with reinforcement welding, act primarily as fixation, do not stress respectively。Counter-force pressure beam 5 two ends are connected with earth anchor 6 by screw rod。Earth anchor 6 is buried middle offer vertically pulling-resistant power by manpower or power auger。
In the application, vertical counter-force pulling seat 3 bottom welding the first base 3-1, pressing beam 5 that top active force is delivered to earth anchor 6 by counter-force, vertical counter-force pulling seat 3 top employing two bar bending side by side becomes U-shaped hook to be welded on the steel pipe of bottom, and U-shaped hook and brace 2, crossbeam 4 are bolted。Totally four, crossbeam 4, symmetry is radiated by centre in same level towards periphery around column, and one end is connected with bottom column 1, and the other end is connected with vertical counter-force pulling seat 3 top, bears pressure, is also key point of the present utility model。
Actual application is embodied as step as follows:
(1) true fixed pile, axis, jack position, adopts tape measure to be measured certain distance by center to surrounding symmetry, it is determined that the particular location of vertical counter-force pulling seat 3, and then determines counter-force pressure beam 5 and earth anchor 6 position。
(2) utilize rig to squeeze in soil by earth anchor 6, place vertical counter-force pulling seat 3, dispose counter-force pressure beam 5 to be connected by nut, nut certain thickness backing plate placed below。
(3) being linked together in brace 2 and column 1 top, two people lift and are placed on the jack placed in advance, stand and directly put surely, and then four groups of brace bottoms are connected fixing by two people respectively with vertical counter-force pulling seat top。
(4) being placed on by crossbeam 4 between column 1 and vertical counter-force pulling seat 3, two ends connect respectively through bolt, finally by the pull bar regulated on brace, whole device adjustment is stably firm, complete the installation of whole device。
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model。
