Embodiment Construction

[0083] Such as Figure 1 to Figure 13 As shown, a method for safe and rapid construction of high pier in turning mode according to the present invention, the high pier is a hollow high pier with a round end and single-sided slope closure, and the method includes the following steps:

[0084] Step 1. Binding of the steel skeleton of the first pier body:

[0085] Step 101, such as figure 2 As shown, the pre-embedded steel bar 20 of the cap is pre-embedded on the cap 19, and the inner operation frame for connecting the main reinforcement of the steel bar is placed in the pre-embedded steel bar 20 of the cap;

[0086] The operating frame in the pier includes two symmetrically arranged semi-pier operating frames 21, the distance between the two semi-pier operating frames 21 is adjusted according to the actual structural size of the pier body, and the semi-pier operating frame 21 includes a half pier The inner operating platform 22, a plurality of first pillars 23 for supporting ...

Abstract

The invention discloses a safe and rapid construction method for a high pier in an overturning mode, which comprises the steps of: 1. Binding of steel skeletons for the first pier body; 2. Formwork support for the first pier body; 3. Concrete pouring for the first pier body; 1. Formwork removal of the first pier body; 5. Inspection platform construction inside the pier; 6. Steel skeleton binding of the standard pier body; 7. Formwork support for the standard pier body; 8. Concrete pouring of the standard pier body; 9. The formwork of the standard section pier body is removed. The invention binds the main reinforcement of the steel bar and the horizontal stirrup of the steel bar skeleton by setting the operating frame inside the pier and the landing protection frame outside the pier, which can improve the binding efficiency of the steel bar on the pier body and ensure the personal safety of the construction workers; In order to ensure the personal safety of the construction personnel during the body-turning formwork construction, the installation position and construction sequence of the frame and platform should be reasonably set to make the construction faster and more efficient, and realize the turnover utilization of construction equipment, which is conducive to reducing construction costs and improving production efficiency. Promotional use.

Description

technical field [0001] The invention belongs to the technical field of high pier turning formwork construction, and in particular relates to a safe and rapid construction method for high pier turning formwork. Background technique [0002] At present, the pier body with a pier height of less than 70m is considered to adopt the high bridge pier construction method of turning over formwork construction in terms of cost, safety and progress. Generally, combined formwork or large steel formwork is used for formwork turning, and the formwork is installed with the cooperation of tower cranes. It has the advantages of being able to complete the construction of high piers efficiently and quickly, and the formwork can be reused many times, so it has a wide range of uses. However, during the construction of the pier body, there are a series of problems such as inadequate safety protection measures for construction personnel, irregular safety passages, and unsafe operating platforms. ...
