Hydraulic pressure movable dam support system of the present invention mainly is made up of dam facing 1, support bar 4 and support bar locking system 6 three parts.Guarantee when dam facing 1 is provided with that basic 3 of dam facing back side 2 and level acutangulate, and the dam facing base is hinged on the support column on the level basis 3.Support bar 4 is arranged at dam facing back side 2 one sides, and its upper end is movably connected in propping up on the ear structure 5 on the dam facing back side 2, and its lower end is slidingly connected on the level basis 3.Support bar locking system 6 mainly is made up of the check device 7 and the hydraulic cylinder 8 that are arranged on the level basis, support bar 4 lower end 3, and hydraulic cylinder extension bar 9 can put in the check device 7 as required, makes support bar 4 lower ends be against on the check device 7 in addition.
As Fig. 2 or shown in Figure 7, check device 7 mainly is made up of perpendicular to symmetrically arranged two wedges 14 of location-plate the location-plate 13 and the location-plate top that are fixedly installed on the level basis 3.Wedge upper surface 18 is irregular transition arc curved-surface structure 15, low two ends height in the middle of its structure.This transition arc curved-surface structure 15 is got relative smaller value away from the end of dam facing one side with the radius of curvature of the transition portion 17 of 16 of mid portions, the stressed support non-return of the whole dam facing when thereby support bar lower union joint 11 is against on the wedge 14, slide from the wedge tail end smoothly for ease of support bar, be down domatic 19 away from the side of dam facing back side 2 at wedge 14.
Technical scheme one of the present invention: arrive shown in Figure 5 as Fig. 1, the mode that adopts hydraulic cylinder extension bar 9 to promote forward, realize the non-return of support bar 4 lower ends and check device 7 and the function of unclamping, be specially: hydraulic cylinder 8 is arranged on the level basis 3 of 7 of dam facing back side 2 and check devices, make hydraulic cylinder extension bar 9 stretch out direction away from dam facing back side 2, hydraulic cylinder extension bar 9 is provided with over against two wedges 14, make the distance of hydraulic cylinder extension bar 9 diameters less than 14 of two wedges, guarantee that hydraulic cylinder extension bar 9 places 14 of two wedges, and the bus of hydraulic cylinder extension bar 9 highest position is higher than wedge upper surface 18, thereby during flood discharge, hydraulic cylinder extension bar 9 is released forward, and support bar lower union joint 11 can be smoothly 9 slides from the hydraulic pressure extension bar.
Technical scheme two of the present invention: as shown in Figure 6 and Figure 7, adopt the upwards mode of jack-up of hydraulic cylinder extension bar 9, realize the non-return of support bar 4 lower ends and check device 7 and the function of unclamping, be specially: hydraulic cylinder 8 is vertically installed in the preformed groove on the level basis 3 under the check device 7, hydraulic cylinder extension bar 9 stretches out 3 surfaces, direction sensing level basis, and hydraulic cylinder extension bar 9 is positioned in the middle of two wedges 14.Hydraulic cylinder extension bar 9 ends are provided with the connector 20 perpendicular to hydraulic cylinder extension bar axis, and the axial distance of connector 20 is less than the distance of 14 of two wedges, and support bar lower union joint 11 is against on the connector 20.Thereby during flood discharge, hydraulic cylinder extension bar 9 is jack-up upwards, and support bar lower union joint 11 can slide from connector 20 smoothly.
Reasonable for the stressing conditions that guarantees the monoblock dam facing, be symmetrical arranged two groups of support bars 4 and two groups of support bar locking systems 6 at dam facing back side 2, thereby share the pressure that upland water causes to dam facing.Correspond to every group of support bar and support bar locking system, the support bar body of rod wherein is a slender rod piece, and its two ends are welded with connector perpendicular to body of rod axis, be respectively upper binding head 10 and lower union joint 11, upper binding head 10 places an ear structure 5 of dam facing back side 2, and lower union joint 11 places on the wedge 14 of check device 7.
Propping up ear structure 5 and be mainly two contiguous blocks perpendicular to the setting of dam facing back side, perhaps is the contiguous block of the approximate C font of a cross section, guarantees during design that an ear structure central indentation width is greater than the support bar diameter.In addition, laterally have pilot hole 12 on the ear structure 5, thereby make support bar upper binding head 10 from pilot hole 12, pass, realize the flexible connection of support bar 4 and dam facing back side 2.Consider the stressed further reasonability of support bar, to be arranged on apart from dam facing side 1/8 dam facing transverse width position with the ear structure 5 that post upper flexibly connects, and it is arranged on 2/5-1/3 dam facing height and position place apart from the dam facing top margin, show through force analysis and dynamic analog, an ear structure 5 of post upper is in the layout of dam facing back side 2, and the dam facing stress performance reaches optimum efficiency.
Wedge 14 guarantees that it is perpendicular to horizontal frontal plane when being installed on the locating piece 13, the support bar lower union joint slides and the angle that saves material that satisfies under the situation of accepting is considered more smoothly during in addition from flood discharge, be down domatic 19 and be designed to domaticly down 20 away from dam facing back side 2 positions on level basis 3 at wedge 14 away from the lateral layout of dam facing back side 4, and following domatic 20 on the level basis is arranged at domatic 19 belows under the wedge.
The mode that adopts hydraulic cylinder extension bar 9 to promote forward, during retaining, as shown in Figure 8, utilize the main hydraulic cylinder system that dam facing 1 is raise, the hydraulic cylinder extension bar 9 that guarantees to be arranged on 7 of dam facing back side 2 and check devices in this process is crossed is away from check device 7, thereby utilize the effect of main hydraulic cylinder system, make the lower union joint 11 of support bar lower end place the arc transition curved-surface structure 15 of check device wedge upper surface 18, utilize low characteristics between its two ends senior middle school, play good non-return effect, thereby play the function of supplemental support dam facing.
The mode that adopts hydraulic cylinder extension bar 9 to promote forward, during flood discharge, as shown in Figure 9, utilize the main hydraulic cylinder system to drive dam facing 1 angle that travels forward, the hydraulic cylinder extension bar 9 that this moment control is arranged on 7 of dam facing back side 2 and check devices approaches check device 7, make hydraulic cylinder extension bar 9 place 14 of check device two wedges, and hydraulic cylinder extension bar 9 ends exceed the transition portion 17 in the 18 arc transition curved-surface structures 15 of wedge upper surface, thereby when unclamping the main hydraulic cylinder system, the lower union joint 11 of support bar lower end along under the hydraulic cylinder extension bar 9 of 7 of dam facing back side 2 and check devices and the wedge domatic 19 and the level basis under domatic 20 slide, realize flood discharge.
Adopt hydraulic cylinder extension bar 9 upwards during the mode retaining of jack-up, at first hydraulic cylinder 8 is vertically installed in the preformed groove on the level basis 3 under the check device 7, make hydraulic cylinder extension bar 9 stretch out 3 surfaces, direction sensing level basis, and hydraulic cylinder extension bar 9 is positioned in the middle of two wedges 14, control hydraulic cylinder extension bar 9 contracts to recovery, thereby the support bar lower end is against transition portion 17 positions in the 18 arc transition curved-surface structures 15 of wedge wedge upper surface, realizes retaining.In addition in order to increase hydraulic cylinder extension bar and support bar lower end contact area, be provided with connector 20 perpendicular to hydraulic cylinder extension bar axis in hydraulic cylinder extension bar 9 ends, the axial distance of connector 20 is less than the distance of 14 of two wedges, thereby support bar lower union joint 11 is against on the connector 20.During flood discharge, hydraulic cylinder extension bar 9 is jack-up upwards, and support bar lower union joint 11 can slide from connector 20 smoothly.
