Specific embodiment
The embodiment that the present invention will be described in detail with reference to the accompanying drawings and examples.
Fig. 1 is that the continuously adjustable of the mined out side slope high voltage power transmission tower in mountainous region that be used for of the invention resists mined out basic stereoscopic structure to show
It is intended to, Fig. 2 is the vertical section figure of isolated footing 1 in Fig. 1, neatly considers for drawing, in Fig. 1, hydraulic the thousand of elevating mechanism
Jin top 8, hoistable platform 9 and the adjusting nut 10 as locking device do not mark, and in Fig. 2, above structure uses lines simple
Change is shown.
As shown in Figure 1, 2, the present invention is mainly improved in the intermediate region up and down of isolated footing 1 and foundation beam 3,
It is cut into a cuboid groove above isolated footing 1, is added to the hydraulic jack 8 of elevating mechanism, placement rises above it
Platform 9 drops.There are four isolated footings 1, and there are four corresponding base stations 4, and four base stations 4 are connected as an entirety, beam by roof beam structure 2
Frame 2 includes four foundation beams 3, and two adjacent base stations 4 are connected by foundation beam 3.In the construction process, base station 4 and foundation beam 3
It is one-piece casting concrete, is later locking device (36 screw rod 5 of Φ and adjusting nut in the overlapping region of base station 4 and foundation beam 3
10) it drills, the number that drills on each base station 4 is 4, and isolated footing 1, foundation beam 3 and base station 4 are existed by locking device
Vertical direction forms one, while four pile foundation beams 3 are connected with each other " mouth " the font roof beam structure 2 of composition, by isolated footing 1 and base station
4 are fixed together in the horizontal plane, form three-dimensional overall structure.Due to mined out perturbation action and slopes gravimetric tilt component
Influence, slope surface soil easily moves horizontally, external force generated to base station 4, this stereochemical structure be able to maintain four base stations 4 it
Between relative position it is constant (root, which is opened, to be basically unchanged), can resist a degree of slope table horizontal distortion, guarantee pylon on base station 4
Safe handling.
Dipmeter 6 is placed among four foundation beams 3 respectively, dipmeter 6 totally four, dipmeter 6 passes through cable and wireless hair
Emitter 7 connects, and wireless transmitter 7 is sent the data of dipmeter to and distally be used to store, handle and show by connection wireless network
The PC machine of registration evidence prepares a computer program according to the data of inclinometer, parameter and related calculation formula and finds out four independent bases
The differential settlement amount of plinth, and range is divided to settling amount, it can be with alert, for maintenance when being more than preset critical
Electric tower foundation provides emergency repair time table.It is capable of the settling amount of remote real-time monitoring isolated footing using this equipment, is obviously improved
The efficiency that electric tower foundation unstability detects in the mined out side slope in mountain area, saves a large amount of human and material resources.
Due to the complex conditions of mined out side slope, lower part is caving rock stratum and gradually transmits to overlying rock, and on slope, table forms depression
Area causes the uneven subsidence of isolated footing 1.By the differential settlement amount of four isolated footings 1 of real-time monitoring, when PC computer
After issuing warning information, manpower is needed to take timely measure the height of four base stations 4 of scene adjustment.Pass through the processing of PC computer
Data adjust the lifting capacity of corresponding base station 4 with hoistable platform and locking device, to realize in Warning years convenient, efficient
Adjustment correction.Adjust the specific steps of correction：The adjusting nut 10 on the screw rod 5 of each base station 4 is unclamped first, is then passed through
Four base stations 4 are tuned into the same horizontal position by corresponding hydraulic jack 8, are adjusted and then are tightened adjusting nut 10.Adjust it
Afterwards, there are certain gaps between general isolated footing 1 and foundation beam 3, can add wood block filler in centre to mitigate hoistable platform 9
Four base stations 4 are made to remain horizontal, pylon is totally in by adjusting four lifting devices with the pressure on locking device
Stable state can be good at the complex geological condition for adapting to the mined out side slope in mountainous region.
The above is only a preferred embodiment of the present invention, however, it is not to limit the invention.It should be pointed out that for
For those skilled in the technology concerned, without departing from the technical principles of the invention, several improvement can also be made
Type, these modifieds also should be regarded as protection scope of the present invention.
