Embodiment 1

[0020] see Figure 1~3 , in Embodiment 1 of the present invention, a reinforcement and protection device for a bridge pile foundation includes a fixed ring 1, the fixed ring 1 is fixedly arranged on the foundation, and a fixed rod 13 arranged inside the foundation is installed on the bottom of the fixed ring 1 , the fixed ring 1 is provided with a hinged seat 2 for connecting one end of the support rod 4, the hinged seat 2 is multiple, and arranged in an array; the hinged seat 2 is fixedly arranged on the fixed ring 1, and the supported rod 4 is provided with a collision block 10 and a contact seat 12, the contact seat 12 is used for the collision of the pile foundation, the collision block 10 is set in cooperation with the driving rod 8 installed on the locking ring 5, and the driving rod 8 is rotated to set On the locking ring 5 , the driving rod 8 is provided with an external thread that cooperates with the internal thread on the locking ring 5 , and a hand wheel is provide...

Embodiment 2

[0028] see Figure 1~2 The main difference between this embodiment 2 and embodiment 1 is that the waterproof structure includes a sealing ring 9 and a support rod 4; a sealing ring 9 is provided at the contact surface between the locking ring 5 and the pile foundation, and the sealing ring 9 is set to prevent rainwater from When the pile foundation flows into the foundation, a waterproof board 3 is arranged between the adjacent support rods 4, which prevents surrounding rainwater from penetrating into the foundation and improves the stability of the pile foundation.

[0029] The working principle of the present invention is:

[0030] First fix the fixed ring 1 on the foundation through the fixed rod 13, then adjust the position of the locking ring 5, connect the first part 14 and the second part 15 through the connecting ear 6 and the bolt 7, and fix them on the pile foundation. The handle on the drive rod 8 drives the drive rod 8 to rotate, and the drive rod 8 moves downward...

Abstract

The invention discloses a reinforcement protection device of a bridge pile foundation, and relates to the technical field of bridge construction. The reinforcement protection device of the bridge pilefoundation comprises a fixing ring, a fixing rod arranged on the inner part of the foundation is mounted at the bottom of the fixing ring, and a plurality of hinged seats used for supporting one endof a supporting rod are arranged on the fixing ring in an array mode; the hinged seats are fixedly arranged on the fixing ring, a contradicting block and a contact seat are arranged on the supportingrod, the contact seat is used for contradicting the pile foundation, drive rods mounted on the contradicting block and a locking ring are arranged in a matching mode, the drive rods are rotatably arranged on the locking ring, the supporting rod is fixedly connected to the lower side of the locking ring through an elastic part, and the reinforcement protection device further comprises a waterproofstructure. The reinforcement protection device is convenient to use, and reinforcement is stable.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a reinforcement and protection device for bridge pile foundations. Background technique [0002] The bridge foundation is the lowest part of the bridge structure directly in contact with the foundation, and is an important part of the bridge substructure. The part of the formation that bears the load from the foundation is called the foundation. After the foundation and foundation are subjected to various loads, they will produce stress and deformation. In order to ensure the normal use and safety of the bridge, the foundation and foundation must have sufficient strength and stability, and the deformation should also be within the allowable range. With the development of the economy and transportation, highway bridges are constantly being built. The pile foundation of the highway bridge is the foundation of the entire highway bridge. Serious safety incident. [000...
