Description

Technical Field

[0001] The invention relates to the field of cast-in-place box girders, and in particular to a hanging basket suspended casting system and a construction method for large-section and wide-width cast-in-place box girders. Background Art

[0002] With the continuous development of modern bridge engineering technology, large-section wide cast-in-place box girder structures have been widely used in bridge construction. This structural form has the advantages of strong bearing capacity, good stability, and convenient construction, but it also puts forward higher requirements on construction technology. As an advanced bridge construction method, hanging basket suspended pouring construction technology plays an increasingly important role in the construction of large-section wide cast-in-place box girders due to its high efficiency, safety, and flexibility.

[0003] Due to the complex structure of large-section wide cast-in-place box girders, each construction link needs to be precisely controlled during the construction process, which increases the difficulty of construction operations. Especially in the hanging basket suspended pouring construction, it is necessary to ensure the stability and safety of the hanging basket, and at the same time ensure the stability of the formwork support. In addition, the cast box girders need to be maintained in a timely manner, which places high demands on the construction personnel's operating skills and experience.

[0004] Based on the actual requirements of complex construction conditions, high construction quality and tight construction period of engineering projects, an innovative hanging basket suspended casting system and construction method for large-section and wide-span cast-in-place box girders with high construction efficiency, excellent construction quality and low safety risk is of great significance for improving the construction quality of large-section and wide-span cast-in-place box girders. Summary of the invention

[0005] The object of the present invention is to provide a large-section wide-width cast-in-place box girder hanging basket suspended casting system and a construction method to solve the above-mentioned technical problems.

[0006] In order to solve the above technical problems, the present invention provides a construction method of a large-section wide cast-in-place box girder hanging basket suspended casting system, comprising the following steps:

[0007] Step 1: Installation of the traveling device of the hanging basket: Install the track on the top surface of the cast-in-place section of the box beam support, install the traveling devices on both sides of the bottom of the hanging basket, and fix the two symmetrically arranged traveling devices by bolts, set the gear on the side of the traveling device, and then install the auxiliary rolling rod and the eight-shaped inner support in sequence;

[0008] Step 2: Preloading of the hanging basket: an embedded plate is set on the cast-in-place section of the box beam support, a force seat bottom plate with a limit card is installed on the walking bottom plate of the hanging basket, and then the angle adjustment square wood is installed between the limit cards, and the distribution beam with the beam limit plate and the beam with the sleeve are installed on several angle adjustment square woods in turn, so that the angle adjustment square wood and the distribution beam are staggered, and then the reaction frame is installed on the embedded plate, and the preloading jack is placed in advance between the beam with the sleeve and the reaction frame. The reaction frame is hoisted after being made as a whole on the ground, and then the hanging basket preloading construction is carried out;

[0009] Step 3: Install the inner mold of the synchronously moving adjustable width truss: sequentially install the width-adjusting top mold, the width-adjusting front mold, the width-adjusting side mold, the width-adjusting truss, and the bottom mold to form the inner mold of the synchronously moving adjustable width truss. The connection points of adjacent width-adjusting trusses are connected through the rear flange. Then, the angle of the bottom mold is fine-tuned by adjusting the bottom mold angle fine-tuning screw and the rotating card. Finally, concrete is poured into the inner mold of the synchronously moving adjustable width truss to form a demoulded box beam.

[0010] Step 4: Intelligent curing device for suspended cast box beam: After the hanging basket slides once, several nozzles are installed on the ABS curing board and telescopic spray column in advance, a roller base is installed at the bottom of the truss, and then a telescopic spray column is installed on the roller base, and the water pipe is connected to the nozzle of the telescopic spray column. An ABS curing board with pipelines is installed on the hanging basket, and the water pipe and temperature and humidity sensor are simultaneously installed on the ABS curing board. The top of the ABS curing board is fixed to the extended track through a foldable connecting rod;

[0011] Step 5. Synchronous movement: When the hanging basket moves forward, it drives the synchronously moving adjustable width truss inner mold and the outer ABS curing plate to move, and the synchronously moving adjustable width truss inner mold drives the telescopic spray column with a roller base to move forward.

[0012] The beneficial effects of the present invention are:

[0013] 1. The present invention adopts the back-pressure preloading technology of the hanging basket jack, optimizes the jack reaction frame, and converts the original oblique force of the jack into a vertical force by adjusting the angle of the square wood, clarifies the force transmission route of the jack preloading, and improves the construction effect of the preloading.

[0014] 2. A synchronously moving and adjustable width truss inner formwork is adopted. This formwork system can construct box girders within a certain width range, thereby improving the turnover rate of the formwork and thus improving the economic benefits.

[0015] 3. The intelligent maintenance device for suspended cast box girders is adopted to improve the construction effect of hanging basket concrete maintenance and further improve the construction quality of hanging basket suspended cast construction. BRIEF DESCRIPTION OF THE DRAWINGS
