Abstract
The invention discloses an automatic deformation adjusting device for a steel face plate dam. A truss is arranged between a dam body and a steel face plate. A plurality of deformation adjusting device bodies with the thrust function are evenly distributed and connected between all supporting points of the truss and the inner wall of the steel face plate, springs are arranged on the outer sides of the deformation adjusting device bodies in a sleeving manner, pressure sensors are installed at one ends or the two ends of the springs, and the thrust of the deformation adjusting device bodies is controlled to be increased or decreased by judging the pressure of the springs. By means of the automatic deformation adjusting device for the steel face plate dam, the local deformation problem of the steel plate dam can be quickly solved, the local stress situation can be found as early as possible and adjusted in time through information feedback of the pressure springs and the pressure sensors, the deformation problem is solved at the micro-deformation stage, and thus larger deformation can be prevented from occurring. The adjusting manner is quick and effective. The structure of the dam body is maintained unchanged integrally, and the service life of the dam body is prolonged.
Description
Technical field
The invention belongs to hydraulic engineering steel facing dam and support regulation technology field, be specifically related to a kind of steel facing dam and automatically adjust deformation device.
Background technology
Steel facing dam is using steel facing as dam body upstream face, prevents dam body from being washed away distortion or impaired by water erosion, guarantees that hydraulic pressure is evenly transmitted to dam body side.Common steel facing dam is as steel facing loose rock 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 distortion, thus cause steel facing local distortion phenomenon.If processed steel facing local distortion not in time, distortion will be accelerated further, finally affect safety of dam body.But, local supporting or the landfill disposal on steel facing dam be accomplished, reach the difficulty making the even object of its inner support power very large, and construction period is longer.Steel facing dam local distortion problem can not be solved by conventional process mode fast accurate, and easily cause supporting dynamics non-uniform phenomenon at work progress, steel facing distortion may be aggravated further.
Summary of the invention
The present invention is directed to the problem that existing steel facing dam occurs that local pressure is uneven and be out of shape, and conventional process mode efficiency is low and the problem of weak effect, provides a kind of steel facing dam automatically to adjust deformation device.
For achieving the above object, the present invention adopts following technical scheme: a kind of steel facing dam adjusts deformation device automatically, between dam body and steel facing, truss is set, and uniformly between each fulcrum and steel facing inwall of truss be connected with multiple deformation adjustment device with thrust, spring is set with outside deformation adjustment device, the one or both ends of spring are provided with pressure sensor, by judging that spring pressure increase carrys out the thrust increase and decrease of controlling distortion adjusting device.
Be provided with control system, each pressure sensor is connected with control system signal input part, and control system output drives corresponding each deformation adjustment device.
Described deformation adjustment device is hydraulic jack, or is adjustable bolt, or is electric pushrod.
Anchor pole is connected with between described truss and dam body.
The present invention has following technique effect:
1, the present invention can quick solution steel facing dam local distortion problem, by the information feed back of compression spring and pressure sensor, can find as early as possible and adjust local pressure situation in time, problem on deformation being solved in the Light deformation stage, thus the generation of more large deformation can be prevented.Adjustment mode is effective rapidly.Keep the structural inconvenience of dam body from entirety, extend the dam body life-span.
2, by arranging control system, automatically the pressure condition of any position can be determined by detected pressures sensor, and the deformation adjustment device that adjustment is corresponding according to local pressure change, realize automatically adjusting object.

Detailed description of the invention
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 uniformly 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.Anchor pole is connected with between steel structure truss 3 and dam body 1.
See Fig. 3, deformation adjustment device 4 is hydraulic jack, is set with spring 5 outside deformation adjustment device 4, and the one or both ends of spring 5 are provided with pressure sensor 6, by judging that the increase of spring 5 pressure carrys out the thrust increase and decrease of controlling distortion adjusting device 4.Can quick solution steel facing dam local distortion problem, by the information feed back of compression spring 5 and pressure sensor 6, can find as early as possible and adjustment local pressure situation in time, problem on deformation be solved in the Light deformation stage, thus the generation of more large deformation can be prevented.Adjustment mode is effective rapidly.Keep the structural inconvenience of dam body 1 from entirety, extend dam body 1 life-span.
Embodiment 2: on embodiment 1 basis, be provided with control system, each pressure sensor 6 is connected with control system signal input part, and control system output drives corresponding each deformation adjustment device 4.By arranging control system, automatically the pressure condition of any position can be determined by detected pressures sensor 6, and the deformation adjustment device 4 that adjustment is corresponding according to local pressure change, realize automatically adjusting object.
Embodiment 3: on embodiment 1 basis, deformation adjustment device 4 is become adjustable bolt, adjustable bolt both sides arrange nut respectively, the hand of spiral 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 regulate by inserting driving lever.
Embodiment 4: on embodiment 1 basis, deformation adjustment device 4 is become electric pushrod, more easily realize automatically controlled object.
