Embodiment Construction

[0026] A method for fixing the maintenance fence of the bridge pier support of a highway bridge and the bridge pier, the method comprising the following steps:

[0027] S1: cast-in-place concrete is built as the substructure of pier 1;

[0028] S2: Binding the upper structural reinforcement of pier 1;

[0029] S3: Use the pre-embedded steel plate 2 as the lateral formwork, and set up the formwork on the lower structure of the pier 1;

[0030] S4: installing several studs 3 vertically through the side wall of the embedded steel plate 2;

[0031] S5: Cast-in-place concrete is built as the upper structure of pier 1;

[0032] S6: welding the maintenance fence 4 to the upper part of the outer wall of the embedded steel plate 2;

[0033] S7: Install the guardrail 5 on the inspection fence 4 .

[0034] The pre-embedded steel plate is an integrally formed steel plate.

[0035] The maintenance fence 4 is composed of several fence units connected end to end.

[0036] The pegs 3 ar...

Abstract

The invention relates to a method for fixedly connecting a highway bridge pier support overhauling fence and a pier and aims to solve the problems that the fixedly-connecting / mode of an existing overhauling fence has difficulty in accurately positioning embedded parts and undergoes the easy displacement of the embedded parts. The method for fixedly connecting the highway bridge pier support overhauling fence and the pier comprises the following steps that: S1, cast-in-place concrete is built into a pier lower structure; S2, binding upper structural steel bars of the pier; S3, with an embeddedsteel plate serves as a lateral formwork, erecting a formwork on the lower structure of the pier; S4, installing a plurality of studs on the side wall of the embedded steel plate in a vertically penetrating mode; S5, building cast-in-place concrete into a pier upper structure; S6, welding an overhaul fence to the upper portion of the outer side wall of a pre-buried steel plate; and S7, installinga guardrail on the overhaul fence. The method is convenient to implement, the formwork purchasing cost and the formwork detaching procedure are omitted, the construction cost is reduced, the installed overhaul fence is accurate in positioning, and the stability, safety and durability of the overhaul fence are effectively improved.

Description

technical field [0001] The invention relates to a construction method for bridge engineering, in particular to a method for fixing a bridge pier maintenance fence and a pier of a highway bridge. Background technique [0002] In bridge engineering, after the bridge is completed, it is necessary to carry out daily maintenance work such as inspection and replacement of bridge supports, pad stones and other structures. The maintenance fence is a safe and effective maintenance facility that provides support for operators and maintenance equipment. Safety protection function to ensure the smooth progress of maintenance operations. At present, the fixed connection between the maintenance fence and the bridge pier is usually welded to the embedded parts. [0003] However, practice shows that the existing fixed connection method of the maintenance fence has the following problems: the embedded parts are prone to shift when pouring concrete, and the precise positioning of the embedde...
