Abstract
The utility model discloses a steel concrete -faced rockfill dam automatic adjustment warp device sets up the truss between dam body and steel facing to the equipartition is connected with a plurality of deformation adjustment devices that have the thrust effect between each fulcrum of truss and steel facing inner wall, and deformation adjustment device outside cover is equipped with the spring, and pressure sensor is installed at the one end or the both ends of spring, controls the thrust increase and decrease of deformation adjustment device through judging the spring pressure increase. The utility model discloses can solve steel concrete -faced rockfill dam local deformation problem fast, through compression spring and pressure sensor's information feedback, can discover and in time adjust the local atress condition as early as possible, solve deformations problems in the micro deformation stage to can prevent the emergence of more large deformation. The adjustment mode is effective rapidly. Keep the designability of dam body inconvenient from whole, the extension dam body life -span.
Description
Technical field
The utility model belongs to hydro project Steel Facing dam and supports regulation technology field, is specifically related to a kind of Steel Facing dam and automatically adjusts deformation device.
Background technology
Steel Facing dam is the face that meets water using Steel Facing as dam body, prevents dam body from being washed away distortion or impaired by water erosion, it is ensured that hydraulic pressure is evenly transmitted to dam body side. Common Steel Facing dam is such as Steel Facing rock fill dam, Steel Facing sand-gravel dam, Steel Facing gravity dam etc. But, due to hydraulic pressure not steadily or the local pressure of Steel Facing can be caused uneven because of dam body local deformaton, thus cause Steel Facing local deformaton phenomenon. If not in time Steel Facing local deformaton being processed, distortion will be accelerated further, finally affect safety of dam body. But, local supporting or the landfill disposal on Steel Facing dam to be accomplished, reach the difficulty making its even object of inner support power very big, and construction period is longer. Steel Facing dam local deformaton problem can not be solved by conventional process mode fast accurate, and easily cause supporting dynamics non-uniform phenomenon at construction process, it is possible to can aggravation Steel Facing distortion further.
Practical novel content
There is, for existing Steel Facing dam, the problem that local pressure is uneven and is out of shape in the utility model, and conventional process mode efficiency is low and the problem of weak effect, it is provided that a kind of Steel Facing dam adjusts deformation device automatically.
For achieving the above object, the utility model adopts following technical scheme: a kind of Steel Facing dam adjusts deformation device automatically, truss is set between dam body and Steel Facing, and uniform between each fulcrum and Steel Facing inwall of truss it is connected with multiple deformation adjustment device with thrust, deformation adjustment device outer sheath is equipped with spring, the one or both ends of spring are provided with pressure transmitter, by judging that spring pressure increase carrys out the thrust increase and decrease of controlling distortion setting device.
Being provided with Controlling System, each pressure transmitter is connected with Controlling System signal input terminus, and Controlling System output terminal drives corresponding each deformation adjustment device.
Described deformation adjustment device is oil jack, or is adjustable bolt, or is electric pushrod.
It is connected with anchor pole between described truss and dam body.
The utility model has following technique effect:
1, the utility model can quick solution Steel Facing dam local deformaton problem, by the information feed back of pressure spring and pressure transmitter, can find as early as possible and adjust local pressure situation in time, problem on deformation be solved in the Light deformation stage, thus the generation of more gross distortion can be prevented. Adjustment mode is effective rapidly. Keep the structure inconvenience of dam body from entirety, extend the dam body life-span.
2, by arranging Controlling System, it is possible to the pressure condition of any position determined by detecting pressure sensor automatically, and corresponding deformation adjustment device is adjusted according to local pressure change, it is achieved automatically adjust object.

Fig. 2 is the Facad structure schematic diagram of Fig. 1;
Fig. 3 is one of partial enlargement structural representation in Fig. 1;
Fig. 4 is two of partial enlargement structural representation in Fig. 1.
In figure, label 1 is dam body, and 2 is Steel Facing, and 3 is steel structure truss, and 4 is deformation adjustment device, and 5 is spring, and 6 is pressure transmitter, and 7 is screw rod, and 8 is nut, and 9 for regulating jack.
Embodiment
Embodiment 1: Steel Facing dam adjusts deformation device automatically see Fig. 1 and Fig. 2, steel structure truss 3 is set between dam body 1 and Steel Facing 2, and uniform between each fulcrum (reinforcing bar intersection) and Steel Facing 2 inwall of steel structure truss 3 is connected with multiple deformation adjustment device 4 with thrust. It is connected with anchor pole between steel structure truss 3 and dam body 1.
See Fig. 3, deformation adjustment device 4 is oil jack, and deformation adjustment device 4 outer sheath is equipped with spring 5, and the one or both ends of spring 5 are provided with pressure transmitter 6, by judging that spring 5 pressure increase carrys out the thrust increase and decrease of controlling distortion setting device 4. Can quick solution Steel Facing dam local deformaton problem, by the information feed back of pressure spring 5 and pressure transmitter 6, it is possible to find as early as possible and adjust local pressure situation in time, by problem on deformation solution in the Light deformation stage, thus the generation of more gross distortion can be prevented. Adjustment mode is effective rapidly. Keep the structure inconvenience of dam body 1 from entirety, extend dam body 1 life-span.
Embodiment 2: on embodiment 1 basis, be provided with Controlling System, each pressure transmitter 6 is connected with Controlling System signal input terminus, and Controlling System output terminal drives corresponding each deformation adjustment device 4. By arranging Controlling System, it is possible to the pressure condition of any position determined by detecting pressure sensor 6 automatically, and adjust corresponding deformation adjustment device 4 according to local pressure change, it is achieved automatically adjust object.
Embodiment 3: on embodiment 1 basis, deformation adjustment device 4 being turned into adjustable bolt, adjustable bolt both sides arrange nut respectively, the screw thread direction of two nuts is contrary, two nuts respectively solid weldings on the fulcrum of Steel Facing 2 and steel structure truss 3. The middle part of adjustable bolt regulates jack, can easily be regulated by insertion driving lever.
Embodiment 4: on embodiment 1 basis, deformation adjustment device 4 is turned into electric pushrod, more easily realize automatically controlled object.
