Problems solved by technology

The climbing formwork method needs to build a scaffold that matches the height of the pier, which takes up a lot of materials and high construction costs; at the same time, it also has the problem of a long construction period

Embodiment Construction

[0015] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0016] see Figure 1 ~ Figure 3 .

[0017] A construction method for a high bridge pier, comprising the steps of:

[0018] 1) Construction preparation

[0019] Before construction, personnel, machinery and equipment, site and other preparations should be made. After the formwork is manufactured in the factory, it should be inspected and tested to see if it meets the design requirements and numbered. After the formwork is transported to the construction site, a trial assembly is required.

[0020] 2) Binding and installing the steel bars of the first pier

[0021] 3) Assembly of the first pier formwork

[0022] The formwork for the first pier section uses at least two formwork sections, upper and lower, and is lifted by tower cranes and i...

Abstract

The invention discloses a method for constructing a high pier, which comprises the following steps of: 1) constructing a first section of pier through at least two upper and lower templates; 2) after concrete strength in a bottom template is more than or equal to 75 percent of design strength and concrete strength in the uppermost template is more than or equal to 2.5Mpa, detaching the bottom template and turning the bottom template above the uppermost template to serve as a second section of pier for installation, and finishing construction of the second section of pier; and 3) repeating the step 2) until construction of the whole pier is finished. Compared with a sliding formwork method, the method has the advantages that: the molding period is short, the pier is convenient to construct, and the method is convenient to operate; and compared with a creeping formwork method, the method has the advantages that: the molding period is short, a high scaffold is not needed to be erected, a few materials are occupied, and construction cost is low. The method has the advantages of sliding formwork and creeping formwork construction methods, the turnover period of the template is short, the construction period of each section of pier is short and is generally about five days, and the concrete joint of the pier has high quality.

Description

technical field [0001] The invention relates to a construction method of a bridge pier, in particular to a construction method of a high bridge pier. Background technique [0002] The bridge is the main component and key part of the expressway, and the construction of high piers is the most difficult and technically content in bridge construction, which is prone to safety hazards and various safety accidents. How to choose a reasonable construction method and take effective control measures to achieve the quality, progress, cost and safety indicators of high pier construction has become the main topic of industry discussion. [0003] At present, the construction methods of high bridge piers mainly include sliding form method and climbing form method. The sliding form method uses hydraulic jacks to lift the formwork from the top of the formwork, and it is necessary to wait for the pier concrete to reach the set strength. The lifting timing is difficult to grasp, the operatio...
