[0018] The utility model will be further described below in combination with the drawings and specific embodiments:

[0019] Embodiment:

[0020] Refer to Figures 1 to 3The embodiment provides a semi-moon type integral guardrail for bridge pier position, which comprises a hanging bucket passageway 1 and two arc-shaped guardrails 2. The hanging bucket passageway 1 is a long strip-shaped concave bucket component. A plurality of T-shaped supporting rods 3 are arranged on one outer side end surface of the hanging bucket passageway 1. The lower part of the T-shaped supporting rod 3 is connected with the hanging bucket passageway 1, and the middle horizontal rod extends backward above the hanging bucket passageway 1. The lower part of the arc-shaped guardrail 2 is connected with the hanging bucket passageway 1, and the distance between the top of the arc-shaped guardrail 2 and the top of the hanging bucket passageway 1 is not less than 1.2 m. A horizontal cross rod 4 is arranged on the end surface of the arc-shaped guardrail 2. The horizontal cross rod 4 is at the same horizontal height as the middle horizontal rod of the T-shaped supporting rod 3. A pull ring is arranged on the arc-shaped guardrail 2.

[0021] The shape of the cross section of the hanging bucket passageway 1 is a right trapezoid, and the T-shaped supporting rod 3 is arranged on the end side plane of one right angle side.

[0022] The arc-shaped guardrail 2 comprises a pair of vertical rods. A guardrail part in a grid shape is arranged between the vertical rods. When the arc-shaped guardrail 2 stands upright, the projection of the guardrail part on the horizontal plane is an arc. An arc-shaped plate is arranged on the lower side of the guardrail part. The horizontal cross rod 4 is arranged on the end surface of the concave side of the arc-shaped plate.

[0023] The number of the T-shaped supporting rods 3 arranged on the hanging bucket passageway 1 is not less than three, and the T-shaped supporting rods 3 are uniformly arranged on the hanging bucket passageway 1. The horizontal rods of the T-shaped supporting rods 3 located on the two sides of the hanging bucket passageway 1 are longer, and the horizontal rod of the T-shaped supporting rod 3 located in the middle is shorter. A reinforcing horizontal rod is arranged between the two adjacent T-shaped supporting rods 3. The length of the horizontal rod of the T-shaped supporting rod located in the middle is designed to be shorter, considering that the T-shaped supporting rod at the position of the bridge pier is for the bridge support, and the length must be controlled to avoid interference with the support. The T-shaped supporting rod in the embodiment is further provided with a reinforcing rib between the upper horizontal rod and the middle horizontal rod.

[0024] The hanging bucket passageway 1 is provided with two. A plane guardrail 5 is arranged between the two hanging bucket passageways 1. The two arc-shaped guardrails 2 are arranged at the opposite end side positions of the two hanging bucket passageways 1. The hanging bucket passageway is designed to be two mainly considering that the middle groove position of the bridge does not need to be constructed, and the plane guardrail can replace the original middle hanging bucket passageway, which is beneficial to improve the gravity center of the integral guardrail structure, avoid the front side being too heavy, and realize the effect of optimizing the stress.

[0025] The pull ring is arranged on the top and the lower part of the arc-shaped guardrail 2, and the pull ring is also arranged on the T-shaped supporting rod 3 of the hanging bucket passageway 1. The pull ring can be used as a tension point to pull the guardrail and the pre-buried part on the bridge pier tightly in addition to being matched with the crane to install the guardrail.

[0026] The hanging bucket passageway 1 and the arc-shaped guardrail 2 are hingedly connected through a hinge. The rotatable arc-shaped guardrail can be adapted to different kinds of bridge pier structures, thereby improving the application range of the device.

[0027] In use of the utility model device in the embodiment, the device needs to be assembled first to form a whole semilunar member; thereafter, two cranes are used to place the semilunar member to the position of the periphery of the pier through the pull ring on the arc-shaped guardrail on two sides, that is, the two arc-shaped guardrails can correspond to the arc-shaped section of the side of the pier, and after the guardrail is in place, the pull ring and the pre-buried member pre-buried on the pier are connected and pulled tightly through the cable, so that the T-shaped supporting rod and the cross rod can be clamped on the edge of the pier; thus, the installation of the guardrail can be completed.
