Embodiment 1
[0041] Such as figure 1 ,Such as figure 2 ,Such as image 3 And as Figure 4 As shown, an assembled reinforcement facility for preventing bridge overturning of the present invention includes a beam body 1, a pier column 2, a steel cap beam 3, a vertical section steel support 4, and a rubber pad 5. The top of the pier column 2 Connected to the beam body 1, the outer wall of the pier column 2 is provided with a steel cover beam 3, the bottom of the pier column 2 is connected with the base, and both sides of the steel cover beam 3 are provided with vertical steel supports 4, the The top end of the vertical section steel support 4 is provided with a rubber block 5, a pressure sensor is arranged inside the rubber block 5, and the rubber block 5 is not connected with the beam 1.
[0042] Working process: During normal operation, the reinforcement facilities and the bridge are only connected by hoop at the top of the pier column, and the reinforcement facilities do not participate in t...
Embodiment 2
[0044] Such as figure 1 ,Such as figure 2 ,Such as image 3 And as Figure 4 As shown, this embodiment is based on embodiment 1. A number of crash barriers are provided on both sides of the beam body 1; the pier column 2 is connected to the beam body 1 through the original bridge support; the steel cover beam 3 and the beam body 1 the same width; the structure of the steel cover beam 3 is a hoop type; the structure of the rubber block 5 is a plate structure; the steel cover beam 3 is composed of a beam top plate 1-1, a number of beam ribs 1-2, and lateral stiffening It consists of a plate 1-3, a beam hoop 1-4 and a beam anchor bolt 1-5. The top of the steel cap beam 3 is provided with a beam top plate 1-1, and the steel cap beam 3 is provided with a beam hoop 1- 4. The beam hoop 1-4 is connected by beam anchors 1-5, the several beam ribs 1-2 are vertically connected in the steel cover beam 3, and the transverse stiffening plates 1-3 are connected transversely Inside the steel...
Embodiment 3
[0046] Such as figure 1 ,Such as figure 2 ,Such as image 3 And as Figure 4 As shown, this embodiment is based on Embodiment 1 and Embodiment 2, and also includes a computer controller, which is electrically connected to a pressure sensor; The device is used to receive the pressure signal collected by the pressure sensor.
[0047] A control method of fabricated reinforcement facilities for preventing bridge overturning based on claim 9, comprising the following steps:
[0048] S1: When the bridge is eccentrically loaded and overturning occurs, the pressure sensor collects the pressure signal of the bridge and transmits it to the computer controller;
[0049] S2: The computer controller receives the pressure signal collected by the pressure sensor, and compares the received pressure signal value with the warning value: if the pressure signal value is less than the warning value, the full bridge can continue to enter the normal operating cycle; such as the pressure signal value Whe...
