The technical effect of the scheme is as follows: after the supporting plate, the supporting bars and the telescopic pipes are disassembled, the inclination degree of the supporting bars can be conveniently and correspondingly adjusted according to the gradient of the dam, so that the supporting plates can be kept in a horizontal state under the condition of different gradients, and the operation of constructors is facilitated; and the backup pad removes to the assigned position after, grabs the ground piece through sliding and removes to drive and grab ground nail and remove and support tightly with dam foundation surface, and then improve the stability of support bar and backup pad, the backup pad can not produce acutely and rock during constructor's operation.
Furthermore, one end of the supporting bar is provided with a hook. The technical effect of the scheme is as follows: the stay cord cover of being convenient for on the one hand drives the support bar and removes when making things convenient for the hoist engine to receive and release the stay cord, and the one end that on the other hand support bar was equipped with the crotch is the arc, reduces the resistance when support bar removes, and the support bar of being convenient for smoothly moves.
Further, be equipped with logical groove on the support bar, grab ground mechanism and still include spacing unit, spacing unit includes stopper and locking piece, stopper and grab land parcel fixed connection, grab the land parcel and slide and set up in leading to the inslot, and the spacing block card cover is on the support bar, and the stopper can pass through locking piece and support bar fixed connection. The technical effect of the scheme is as follows: carry on spacingly and fixed through grabbing the landmass, be favorable to improving the stability of grabbing the landmass, and then improve the stability of support bar.
Furthermore, the supporting bars are provided with sliding grooves, the sliding blocks are arranged in the sliding grooves in a sliding mode, the height of each cushion block is larger than the depth of each sliding groove, and each cushion block can slide to a position between the limiting block and the bottom of each sliding groove. The technical effect of the scheme is as follows: when the supporting bar needs to be moved, the ground grabbing block is moved to separate the ground grabbing nail from the foundation surface of the dam, the limiting block is supported by the cushion block in the process of moving the supporting bar, the ground grabbing block can be prevented from being moved to reset, and the ground grabbing nail is prevented from contacting with the foundation surface of the dam.
Furthermore, the cross section of the cushion block is convex. The technical effect of the scheme is as follows: when the cushion block does not support the limiting block, the cushion block is prevented from falling from the sliding groove.
Furthermore, a guardrail is arranged on the supporting plate. The technical effect of the scheme is as follows: is beneficial to improving the safety of constructors.
