Problems solved by technology

[0003] After research, it was found that during the construction of the bridge pier body, the newly poured section will have local grout leakage during the construction process, and the maintenance water will flow down the pier body, polluting the poured bridge pier body of the lower section, causing the pier body to be damaged. The appearance quality is poor, which affects the image of the project entity and has a negative impact on the construction unit

Abstract

The invention relates to a bridge pier body anti-pollution system for creeping formwork construction; the system comprises a water collecting tank, a connector water collecting tank, a water collecting tank bracket, a main water pipe and a jacking device, and the water collecting tank bracket is fixed to a creeping formwork bearing tripod vertical rod; the water collecting tank is erected on the water collecting tank bracket, the water collecting tank is erected around the bridge pier body, and a plurality of connecting ports are reserved in the water collecting tank around the bridge pier body; the two ends of the connecting port water collecting tank are respectively erected on the water collecting tanks at the two ends of the connecting port; a water collecting basket for receiving cement paste and maintenance water flowing down from the connecting port is mounted at each connecting port; the bottoms of the water collecting baskets are communicated with branch water pipes which are communicated with a main water pipe, and the main water pipe is connected with a discharge pipe; the jacking device is installed on the water collecting tank bracket and used for tightly pressing the water collecting tank and the connector water collecting tank to be attached to the bridge pier body, and water stop strips are arranged on the attaching faces of the water collecting tank and the bridge pier body and the attaching faces of the connector water collecting tank and the bridge pier body. The system is convenient to install, and cement paste and maintenance water flowing downwards from the pier top can be effectively collected.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a bridge pier anti-pollution system for climbing formwork construction. Background technique [0002] With the rapid development of high-speed railways and expressways, the number of bridges in mountainous areas has increased significantly, and high-pier bridges have become more and more common. The main construction schemes for high-pier girder bridge piers include turning form construction, climbing form construction and slip form construction. Among them, climbing formwork is the abbreviation of climbing formwork, also called jumping formwork. It consists of three parts: climbing formwork, climbing frame (some climbing forms have no climbing frame) and climbing equipment. Like the sliding formwork, it is attached to the vertical structure of the building during the structural construction stage and rises layer by layer with the structural construction. It is an ef...
