Verticality control device for slip-form construction of high bridge pier and using method thereof

Abstract

The invention discloses a verticality control device for slip-form construction of a high bridge pier. The device comprises a template truss installed on the high bridge pier and in the shape of a cuboid, four horizontal pipes, two dividing rulers, four laser emitters, and four laser reception areas. The horizontal pipes correspond to each top side of the template truss one by one and arranged on all top sides of the template truss. The two dividing rulers are arranged on a pair of side surfaces of the template truss. Each dividing ruler is provided with two laser emitters. The four laser reception areas are arranged on a support table and correspond to the laser emitters one by one and are used for receiving corresponding lasers emitted by the laser emitters. The verticality control device for slip-form construction of the high bridge pier has following beneficial effects: by controlling positioning in horizontal and vertical directions, measurement and examination of a template during slip-form construction is replaced; horizontal adjustments and vertical positioning can be carried out easily and rapidly to ensure perpendicularity of the high bridge pier; at the same time, perpendicularity of the high bridge pier can be reexamined at any time; and timeliness is obtained.

Problems solved by technology

[0002] With the continuous increase of national mountain highways and railway construction mileage, more and more bridges span complex geological zones during the construction process, and the construction proportion of high bridge piers is also increasing. In order to meet the needs of the construction process, some high bridge piers Sliding form construction is adopted, but the higher the pier is, the more difficult it is to control the verticality, and the frequency of checking the formwork during the process is high, and it is difficult for workers to adjust the formwork during the sliding process, which affects the construction efficiency. less than good protection

[0003] In the construction of reinforced concrete structures nowadays, the form work is labor-intensive and takes up a lot of materials, and the construction period is also long. Therefore, the total cost of a single project depends largely on the form work. For high pier structures, this point It is even more obvious that people try to simplify the formwork project as much as possible. In many cases, it is a correct choice to adopt the sliding form construction technology, but it is difficult to control the verticality of the high pier during the construction process. The verticality is in an unbiased state to ensure the uniform force of the high piers, which is very important to the safety and quality of the bridge

[0004] At present, during the sliding form construction of high bridge piers, most construction sites basically use total stations to control the verticality and elevation to ensure the verticality of high piers, and check the position and elevation on the formwork to ensure accurate positioning, but the actual determination of verticality The most important factors are the frequency of template verification in the process and the timeliness of workers' control during the sliding process. Therefore, the existing problems in the verticality "timeliness" control of the prior art must be solved, and the verticality control operation is very difficult, and the deviation is not easy to control. During the detection process, the verticality cannot be reflected intuitively, and the on-site detection is carried out by technicians, which leads to the detachment of the construction layer from the detection, and the deviation cannot be corrected in time
