Bridge construction supporting foundation construction process

Abstract

The invention relates to a bridge construction supporting foundation construction process which uses a bridge pier shaping device. The bridge pier shaping device comprises a base, a frame unit and a locking unit, wherein the frame unit is arranged at the upper end of the base in a spliced mode, and the locking unit is arranged on the left side of the upper end of the base. The size of a bridge pier poured in the frame is changed by adding adjustment, pouring of bridge piers of different specifications is achieved through the device in the production process, and therefore the device adapts toinstallation and placement of bridge piers under different terrains and spaces; by means of a rotary locking mode, the spliced frame is locked in a framing mode through the lock frame, and meanwhile,by locking the supporting columns on the outer surface of the frame, the problem that the joint is not tight after the spliced frame is used for multiple times is solved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a construction technology of a bridge construction support foundation. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. 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 bo...

AI Technical Summary

Problems solved by technology

[0003] In the process of building bridge piers, it is usually necessary to assemble the frame to cast the bridge piers. In the process of assembling the frame, the following problems are often encountered: 1. According to the size of the bridge, the size of the abutment and the bridge piers are often inconsistent, but the construction Different frames need to be replaced for different piers, which increases the construction cost of the bridge; 2. The joints of the assembled frames are often not tight after repeated use, which makes the built piers protrude too much and are unsightly
