Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1-5, a water conservancy construction cofferdam device, including cofferdam structure 1, the cross section of cofferdam structure 1 is the rectangle, and four outside of the rectangle all correspond and set up baffle 2, and install between baffle 2 and the cofferdam structure 1 and turn to the structure, wherein turn to the structure and include fixed block 5, spout 6, slider 7, slide bar 8, spring 9 and connecting rod 10, namely fixed block 5 is fixed with in the side both sides of cofferdam structure 1, spout 6 has all been seted up to the upper and lower both sides of every fixed block 5, and all slidable mounting has slider 7 in the inside of every spout 6, and slidable mounting has slider 8 in the inside of slider 7, the both ends of slider 8 are all fixed in the inside of spout 6, still overlap in the outside of slider 8 simultaneously and be equipped with spring 9, it has connecting rod 10 to articulate at the tip of slider 7, the other end of connecting rod 10 then articulates on baffle 2.

The cofferdam structure 1 has strong water pressure at the inner side and the outer side of the cofferdam in the using process, the water pressure has a pressure vertical to the side surface of the cofferdam structure 1, the cofferdam structure 1 is not beneficial to the normal use of the cofferdam structure 1 in the state for a long time, through the technical scheme, when the baffle 2 at the outer side in the using process of the cofferdam structure 1 also forms a relatively sealed space, the water between the baffle 2 and the cofferdam structure 1 can be pumped away after the installation is finished, the water pressure can act on the side plate at the moment, and then the cofferdam structure 1 at the inner side can be protected, meanwhile, when the baffle 2 is subjected to the pressure vertical to the side plate, the side plate moves in a small range, and simultaneously drives the waterproof pad 3 between the side plates to deform, pressure transmits connecting rod 10, connecting rod 10 slopes gradually under the effect of pressure, promote slider 7 of connecting rod 10 tip gradually and slide outside spout 6 and slide bar 8 in the in-process of slope, the spring 9 of establishing to the cover on the slide bar 8 extrudes in gliding time, from this can know the effect of perpendicular and curb plate's pressure through connecting rod 10, turn into the power of parallel and curb plate and order about spring 9 and compress, and then can convert the pressure that transmits into vertical power, and carry out the partial loss, thereby the size of the vertical force that reducible inboard cofferdam structure 1 received, protect cofferdam structure 1 once more, and then can reduce the damage of pressure to cofferdam structure 1, improve whole cofferdam structure 1's life.

Specifically, cofferdam structure 1 includes guide pile 11, steel-pipe pile 12, backup pad 13 and spacing frame 14, guide pile 11 sets up the corner at cofferdam structure 1, and the guide pile 11 of corner sets up in pairs, and fixed block 5 then fixes on guide pile 11, fixed mounting has backup pad 13 between the guide pile 11 that sets up in pairs, fixed mounting has spacing frame 14 on backup pad 13, install a plurality of steel-pipe piles 12 between the spacing frame 14, simultaneously there is stiffener 15 at the inboard fixed mounting of spacing frame 14, and stiffener 15 slope sets up, a plurality of steel-pipe piles 12 are in the same place through the mode sealing installation of pegging graft.

According to the technical scheme, firstly, the guide piles 11 are driven by the vibration hammer to be fixed, then the supporting plates 13 are fixedly installed between the guide piles 11 in pairs, the limiting frames 14 are fixedly installed on the supporting plates 13, then the steel pipe piles 12 sequentially penetrate through the limiting frames 14 through the vibration hammer to be driven underground, and the reinforcing rods 15 can increase the overall strength of the cofferdam structure 1.

When using, the baffle 2 and the waterproof pad 3 in the outside protect inboard cofferdam structure 1, and pressure can convert it into the power of perpendicular and curb plate through articulated connecting rod 10 that sets up, and order about the slip of the slider 7 of perpendicular setting on slide bar 8, and extrude spring 9, consume the pressure that the transmission came, thereby can effectively reduce the vertical force that inboard cofferdam structure 1 received, reduce the damage to cofferdam structure 1, and then effectively improve cofferdam structure 1's life.
