Problems solved by technology

At present, many bridge piers will be built in rivers and rivers. They not only need to withstand the pressure of flowing water, but also soak in water for a long time, which often causes many microorganisms and small animals such as algae and snails in the water to adhere to the outside of the bridge piers. A large number of microorganisms and attached The adsorption of small organisms will cause the pier to be corroded and eroded, and a long time will cause the quality of the pier to decline, and even cause safety problems

Embodiment 1

[0040] Such as figure 1 As shown, the protective device provided on the bridge pier provided by the present invention includes a pier column 4 fixedly connected to the bridge deck 5, the lower side of the pier column 4 is provided with a pier platform 3 and a pier body 2 in sequence, and the lower side of the pier body 2 The set foundation 1 is fixedly arranged on the river bed, and the outer side of the pier column 4 is provided with several solar panels 6 electrically connected to the storage battery, and the storage battery is electrically connected to the air pump 7 provided with the controller, and the air pump 7 passes through the pier body 2, the pier abutment 3 and the pipeline provided inside the pier column 4 are airtightly connected with several air injection devices 8 arranged on the outside of the pier body 2 .

[0041] Such as figure 2 As shown, the air injection device 8 specifically includes an air inlet pipe 84 that is airtightly connected to the pipeline ar...

Embodiment 2

[0044] This embodiment is further improved on the basis of the above-mentioned embodiment 1, and other structures are the same, the difference is that: Figure 4 As shown, the outer side of the pier body 2 is provided with several electrodes 9 electrically connected to the storage battery, the electrodes 9 and the gas injection device 8 are arranged at intervals, and the circuits of the electrodes 9 are arranged on the tubes inside the pier body 2, the pier platform 3 and the pier column 4. Waterproof and airtight connections are made inside the road. When the microorganisms and plankton in the river water are near the pier body 2, the control device starts the electrode 9 to continuously discharge. The compressed air ejected from the air outlet of the air nozzle 82 in the air injection device 8 will spray away the electrocuted microorganisms and plankton smoothly, so as to reduce the adhesion and erosion to the pier body 2 .

[0045] Such as Figure 5-7 As shown, in a furthe...

Abstract

The invention belongs to the technical field of road and bridge facilities, and particularly relates to a protection device arranged on a bridge pier and a construction method of the protection device. The protection device arranged on the bridge pier comprises a pier column fixedly connected with a bridge plate, the lower side of the pier column is sequentially provided with a pier platform and apier body, a foundation on the lower side of the pier body is fixedly arranged on the riverbed, the outer side of the pier column is provided with a plurality of solar panels electrically connected with a storage battery, the storage battery is electrically connected with an air pump provided with a controller, the air pump is in airtight connection with a plurality of air jet devices arranged onthe outer side of the pier body through pipelines arranged inside the pier body, the pier platform and pier column, and electrodes and protection plates are arranged between the air jet devices correspondingly. The corrosion of microorganisms and plankton in water to the bridge pier can be reduced, and the service life of the bridge pier is prolonged. Solar energy is used as an energy source, pollution cannot be generated, environmental protection is realized, maintenance is more convenient and easier, and wide application can be realized.

Description

technical field [0001] The invention belongs to the technical field of road and bridge facilities, and in particular relates to a protective device arranged on a bridge pier and a construction method thereof. Background technique [0002] A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; Or the force transmission device installed at the supporting place of the bridge abutment; the auxiliary structures refer to the bridge head board, conical slope protection, bank protection, diversion works, etc. Among them, the role of the pier is to support the vertical force and horizontal force transmitted from the upper structure of its left and right spans through the support. At present, many bridge piers will be built in rivers and rivers. They not only need to ...
